Errors in soil moisture data cost scientists hours of wasted time sifting through datasets trying to figure out what is real and what is installation error. We’ve spent the past 20 years focusing on the accuracy of the sensor itself. With the TEROS 12, we’ve not only improved our sensor, we’ve also turned our attention to broader issues that are likely to confound soil moisture data—things like sensor-to-sensor variability, volume of influence, air gaps, and preferential flow. Learn about: TEROS 12 data consistency and response to wetting fronts How the new calibration procedure works to minimize sensor-to-sensor variability How the installation tool reduces air gaps and site disturbance while improving consistency What to expect during an installation

Soil Moisture 202: Choosing the Right Water Potential Sensor
by Leo Rivera, METER Research Scientist
Water potential is the most fundamental and essential measurement in soil physics because it describes the force that drives water movement. Making good water potential measurements is largely a function of choosing the right instrument and using it skillfully. In an ideal world, there would be one instrument that simply and accurately measured water potential over its entire range from wet to dry. In the real world, there is an assortment of instruments, each with its unique personality. Each has its quirks, advantages, and disadvantages. Each has a well-defined usable range.
Which sensor is right for you?
In this 20-minute webinar, METER research scientist Leo Rivera discusses how to choose the right field water potential sensor for your application.
Learn:
• Why you should measure water potential
• Which part of the water potential range each sensor measures
• The technology behind each method: tensiometers, granular matric sensors, heat dissipation sensors, thermocouple psychrometers, and capacitance sensors.
• The pros and cons of each method
• Which sensors are best for certain applications
Soil Moisture: Why Water Content Can’t Tell You Everything You Need to Know
Water content can leave you in the dark
Everybody measures soil water content because it’s easy. But if you’re only measuring water content, you may be blind to what your plants are really experiencing.
Soil moisture is more complex than estimating how much water is used by vegetation and how much needs to be replaced. If you’re thinking about it that way, you’re only seeing half the picture. You’re assuming you know what the right level of water should be—and that’s extremely difficult using only a water content sensor.
Get it right every time
Water content is only one side of a critical two-sided coin. To understand when to water or plant water stress, you need to measure both water content and water potential. In this 30-minute webinar, METER soil physicist, Dr. Colin Campbell, discusses how and why scientists combine both types of sensors for more accurate insights. Discover:
- Why the “right water level” is different for every soil type
- Why soil surveys aren’t sufficient to type your soil for full and refill points
- Why you can’t know what a water content “percentage” means to growing plants
- How assumptions made when only measuring water content can reduce crop yield and quality
- Water potential fundamentals
- How water potential sensors measure “plant comfort” like a thermometer
- Why water potential is the only accurate way to measure drought stress
- Why visual cues happen too late to prevent plant-water problems
- Case studies that show why both water content and water potential are necessary to understand the condition of soil water in your experiment or crop
Soil Moisture 302: Hydraulic Conductivity
Which instrument is right for you?
Soil hydraulic conductivity is the ability of a soil to transmit water in saturated, nearly saturated, or unsaturated conditions. But measuring hydraulic conductivity can be confusing. Which measurement is right for your application: saturated or unsaturated hydraulic conductivity? And which instrument should you use?
Make the right choice
In Soil Moisture 302, Leo Rivera, Research Scientist at METER, teaches which situations require saturated or unsaturated hydraulic conductivity and the pros and cons of common methods used to measure both parameters. Find out:
• When to measure saturated hydraulic conductivity
• When to measure unsaturated hydraulic conductivity
• Instruments that measure each parameter
• The technology behind each instrument
• Advantages vs. disadvantages of each method
Soil Moisture 101: Need-to-know Basics
Many researchers measure evapotranspiration and precipitation to understand the fate of water—how much is deposited and how much is used and leaving the system. But if you only measure withdrawals and deposits, you’re missing out on water that is (or is not) available in the soil moisture savings account. Soil moisture is a powerful tool you can use to predict how much water is available to plants, if water will move, and where it’s going to go next. Understanding soil moisture is more than just measuring the amount of water in soil. Learn the basic principles you need to know before you choose how to measure it.
Presented by: Chris Chambers, METER Environment
Hydraulic Conductivity: How Many Measurements Do You Need?
Two researchers show easier methods conform to standards
If you’re measuring saturated hydraulic conductivity with a double ring infiltrometer, you’re lucky if you can get two tests done in a day. For most inspectors, researchers, and geotechs—that’s just not feasible. Historically, double ring methods were the standard, however the industry is now more accepting of faster single ring methods with the caveat that enough locations are tested. But how many locations are enough?
Triple the tests you run in a day
Drs. Andrea Welker and Kristin Sample-Lord, researchers at Villanova University, are changing the way infiltration measurements are captured while keeping the standards of measurement high. They ran many infiltration tests with three types of infiltrometers with a variety of sizes and soil types. In this 30-minute webinar, they’ll discuss what they found to be the acceptable statistical mean for a single rain garden. Plus, they’ll reveal the pros and cons of each infiltrometer type and which ones were the most practical to use. Learn:
- What types of sites were tested
- How the spot measurements compared with infiltration rates over the whole rain garden
- Pros and cons of each infiltrometer and how they compared for practicality and ease of use
- What is an acceptable number of measurements for an accurate assessment
Soil Moisture 102: Water Content Methods–Demystified
In this 20-minute webinar, Dr. Colin Campbell demystifies the differences between soil water content measurement methods. He explores the scientific measurement theory and the pros and cons of each method. He also explains which technology might apply to different types of field research, and why modern sensing is about more than just the sensor.
Learn:
• Measurement theory behind the gravimetric method, capacitance, time-domain reflectometry (TDR), time-domain transmission (TDT), frequency-domain reflectometry (FDR), resistance sensors, and more
• Which technology applies to different field situations
• What factors matter when choosing a sensor type
• Why some methods are not research-grade
• How modern sensing is about more than just the sensor
• How to determine a good price-to-performance ratio for your unique application
Soil Moisture 201: Moisture Release Curves
Are you interested in the water stored in the soil? Do you care more about water available for primary productivity? Are you studying water and solute movement in soils? Do you aim to optimize water use of crops? Are you modeling soil hydrology?
After this webinar you will:
• You will have a better understanding of the importance of water potential
• How you can utilize soil moisture release curves for irrigation planning
• What additional information lives within the soil moisture release curve
• What factors affect field capacity

Brian Leib, Managed Depletion Irrigation
How to maximize yields with the least amount of water
Replacing crop water use to a full point or field capacity is a common approach to irrigation scheduling. At least, that’s true in arid climates. But what if there’s a repeat chance of rain?
Uncertainty of rainfall amount and timing can impact how we approach irrigation water management. In humid regions, bringing the soil to full field capacity often means lost yield potential.
Brian Leib, Ph.D., from the University of Tennessee presents this webinar presentation to discuss a new approach to managing irrigation. He’ll share past studies and results using different irrigation treatments in soybean and cotton crops.
Learn how to:
• Manage for rainfall in humid regions
• Avoid issues with runoff to low, poorly drained areas
• Promote reproductive growth and root development
• Adapt principles from arid climates
Predictable Yields Using Remote and Field Monitoring
What happens when you take satellite products and add soil water potential data?
New data sources offer tools for growers to optimize production in the field. But the task of implementing them is often difficult. Research work is underway and offers a guide on how data from soil and space can work together to make the job of irrigation scheduling easier.
In this presentation, METER’s Dr. Colin Campbell explains the formula for prescribing irrigation events that will get you the yields you want.

How to improve irrigation scheduling using soil moisture
By: Dr. Gaylon S. Campbell
Every irrigator wishes for tools that answer the fundamental questions: when do I turn the water on and when do I turn the water off? The challenge is figuring out the right ones and implementing them effectively. New sensor technology and cloud computing offer new opportunities to growers, but it is often unclear how to put these into practice.
In this 30-minute webinar, Dr. Gaylon Campbell will cover the different methods for irrigation water management and the pros and cons of each. Best practices for soil moisture monitoring and costs of improper irrigation scheduling will also be discussed.
Learn:
• Why we schedule irrigation
• Different methods used by growers to decide when to irrigate
• Steps for scheduling irrigation using soil moisture
• Results from good management and the consequences of mistakes
Irrigation Management: Plant-Water Relations and Atmospheric Demand

Irrigation of Controlled Environment Crops for Increased Quality and Yield
Part 1: Substrates and Water
Stop guessing. Start measuring.
When you irrigate in a greenhouse or growth chamber, you need to get the most out of your substrate so you can maximize the yield and quality of your product. But if you’re lifting a pot to gauge how much water is in the substrate, it’s going to be difficult—if not impossible—to achieve your goals. To complicate matters, soil substrates and potting mixes are some of the most challenging media in which to get the water exactly right.
Without accurate measurements or the right measurements, you’ll be blind to what your plants are really experiencing. And that’s a problem, because irrigating incorrectly will reduce yield, derail the quality of your product, deprive the roots of oxygen, and increase risk of disease.
Supercharge yield, quality—and profit
At METER, we know how to irrigate substrates. We’ve been measuring soil moisture for over 40 years. Join Dr. Gaylon Campbell, founder, soil physicist, and one of the world’s foremost authorities on soil, plant, and atmospheric measurements, for a series of irrigation webinars designed to help you correctly control your crop environment to achieve maximum results. In this 30-minute webinar, learn:
Why substrates hold water differently than normal soil
How the properties of different substrates and potting mixes compare
Why it’s difficult if not impossible to irrigate correctly without accurately measuring the amount of water in the substrate

- How the ATMOS 41 microenvironment monitor combined with the ZL6 logger and ZENTRA Cloud give easy access to crop ET data
- How v can be controlled by manipulating plant water potential using appropriate irrigation strategies
- Why combining monitoring soil water potential with deficit irrigation based on ET estimates provide an efficient and precise method for controlled water stress management
- And more…Evapotranspiration: Pitfalls to Avoid and Why It’s Easier Than You Think
Mistakes that kill your estimates
Measuring evapotranspiration (ET) to understand water loss from a native or a managed ecosystem is easier than it looks, but you have to know what you’re doing. If you can’t spend the time or money on a full eddy-covariance system, you’ll have to be satisfied with making some assumptions using equations such as Penman-Monteith.
Like any model, the accuracy of the output depends on the quality of the inputs, but do you know what measurements are critical for success? Plus, as your instrumentation gets more inaccurate, the errors get larger. If you’re not careful, you can end up with no idea what’s happening to the water in your system.
Get the right number every time
You don’t have to be a meteorologist or need incredibly expensive equipment to measure ET effectively. In this 30-minute webinar, Campbell Scientific application scientist Dr. Dirk Baker and METER research scientist Dr. Colin Campbell team up to explain:
- The fundamentals of energy balance modeling to get ET
- Assumptions that can simplify sensor requirements
- What you must measure to get adequate ET estimates
- Assumptions and common pitfalls
- How accurate your equipment should be for good estimates
- Causes and implications of uncertainty
Improve Your Plant Study: 3 Types of Environmental Data You May Be Missing
What data are you missing?
As a plant researcher, you need to effectively assess crop performance, whether it’s yield or disease resistance. But if you’re only measuring weather data, you might be missing key performance indicators in your variety trials. Understanding the full picture of the environment will make it easier to select the right varieties to advance—and avoid wasting resources on advancing bad selections.
To accurately assess plant stress tolerance, you must first characterize all environmental stressors. For example, drought studies are notoriously difficult to replicate because of high weather variability. Precipitation data is not enough to assess drought. You need a tool to quantify drought at the soil level.
Get better, more accurate conclusions
It’s important for your environmental data to accurately represent the environment of your site. That means not only capturing the right parameters but choosing the right tools to capture them. In this 30-minute webinar, application expert Holly Lane discusses how to improve your current data and what data you may not be collecting that will optimize and improve the quality of your plant study. Find out:
- How to know if you’re asking the right questions
- Are you using the right atmospheric measurements? And are you measuring weather in the right location?
- Which type of soil moisture data is right for the goals of your research or variety trial
- How to improve your drought study, why precipitation data is not enough, and why you don’t need to be a soil scientist to leverage soil data
- How to use soil water potential
- How accurate your equipment should be for good estimates
- Key concepts to keep in mind when designing a plant study in the field
- What ancillary data you should be collecting to achieve your goals

Water Potential 101: What It Is. Why You Need It. How To Use It.
Soil is no longer a black box. Advances in sensor technology and software now make it easy to understand what’s happening in your soil, but don’t get stuck thinking only measuring soil water content will tell you what you need to know. Water content is only one side of a critical two-sided coin. To understand when to water, plant-water stress, or how to characterize drought, you also need to measure water potential.
Better data. Better answers.
Soil water potential is a crucial measurement for optimizing yield and stewarding the environment because it’s a direct indicator of availability of water for biological processes. If you’re not measuring it, you’re likely getting the wrong answer to your soil moisture questions. Water potential can also help you predict if soil water will move, and where it’s going to go. Join METER soil physicist, Dr. Doug Cobos, as he teaches the basics of this critical measurement. Learn:

Irrigation of Controlled Environment Crops for Increased Quality and Yield
Part 1: Substrates and Water
Stop guessing. Start measuring.
When you irrigate in a greenhouse or growth chamber, you need to get the most out of your substrate so you can maximize the yield and quality of your product. But if you’re lifting a pot to gauge how much water is in the substrate, it’s going to be difficult—if not impossible—to achieve your goals. To complicate matters, soil substrates and potting mixes are some of the most challenging media in which to get the water exactly right.
Without accurate measurements or the right measurements, you’ll be blind to what your plants are really experiencing. And that’s a problem, because irrigating incorrectly will reduce yield, derail the quality of your product, deprive the roots of oxygen, and increase risk of disease.
Supercharge yield, quality—and profit
At METER, we know how to irrigate substrates. We’ve been measuring soil moisture for over 40 years. Join Dr. Gaylon Campbell, founder, soil physicist, and one of the world’s foremost authorities on soil, plant, and atmospheric measurements, for a series of irrigation webinars designed to help you correctly control your crop environment to achieve maximum results. In this 30-minute webinar, learn:
Why substrates hold water differently than normal soil
How the properties of different substrates and potting mixes compare
Why it’s difficult if not impossible to irrigate correctly without accurately measuring the amount of water in the substrate
The fundamentals of measuring soil moisture: specifically water content and electrical conductivity
How measuring soil moisture helps you get the most out of the substrate you choose, so you can improve your product

- And more…Evapotranspiration: Pitfalls to Avoid and Why It’s Easier Than You Think
Mistakes that kill your estimates
Measuring evapotranspiration (ET) to understand water loss from a native or a managed ecosystem is easier than it looks, but you have to know what you’re doing. If you can’t spend the time or money on a full eddy-covariance system, you’ll have to be satisfied with making some assumptions using equations such as Penman-Monteith.
Like any model, the accuracy of the output depends on the quality of the inputs, but do you know what measurements are critical for success? Plus, as your instrumentation gets more inaccurate, the errors get larger. If you’re not careful, you can end up with no idea what’s happening to the water in your system.
Get the right number every time
You don’t have to be a meteorologist or need incredibly expensive equipment to measure ET effectively. In this 30-minute webinar, Campbell Scientific application scientist Dr. Dirk Baker and METER research scientist Dr. Colin Campbell team up to explain:
- The fundamentals of energy balance modeling to get ET
- Assumptions that can simplify sensor requirements
- What you must measure to get adequate ET estimates
- Assumptions and common pitfalls
- How accurate your equipment should be for good estimates
- Causes and implications of uncertainty
Improve Your Plant Study: 3 Types of Environmental Data You May Be Missing
What data are you missing?
As a plant researcher, you need to effectively assess crop performance, whether it’s yield or disease resistance. But if you’re only measuring weather data, you might be missing key performance indicators in your variety trials. Understanding the full picture of the environment will make it easier to select the right varieties to advance—and avoid wasting resources on advancing bad selections.
To accurately assess plant stress tolerance, you must first characterize all environmental stressors. For example, drought studies are notoriously difficult to replicate because of high weather variability. Precipitation data is not enough to assess drought. You need a tool to quantify drought at the soil level.
Get better, more accurate conclusions
It’s important for your environmental data to accurately represent the environment of your site. That means not only capturing the right parameters but choosing the right tools to capture them. In this 30-minute webinar, application expert Holly Lane discusses how to improve your current data and what data you may not be collecting that will optimize and improve the quality of your plant study. Find out:
- How to know if you’re asking the right questions
- Are you using the right atmospheric measurements? And are you measuring weather in the right location?
- Which type of soil moisture data is right for the goals of your research or variety trial
- How to improve your drought study, why precipitation data is not enough, and why you don’t need to be a soil scientist to leverage soil data
- How to use soil water potential
- How accurate your equipment should be for good estimates
- Key concepts to keep in mind when designing a plant study in the field
- What ancillary data you should be collecting to achieve your goals

Water Potential 101: What It Is. Why You Need It. How To Use It.
Soil is no longer a black box. Advances in sensor technology and software now make it easy to understand what’s happening in your soil, but don’t get stuck thinking only measuring soil water content will tell you what you need to know. Water content is only one side of a critical two-sided coin. To understand when to water, plant-water stress, or how to characterize drought, you also need to measure water potential.
Better data. Better answers.
Soil water potential is a crucial measurement for optimizing yield and stewarding the environment because it’s a direct indicator of availability of water for biological processes. If you’re not measuring it, you’re likely getting the wrong answer to your soil moisture questions. Water potential can also help you predict if soil water will move, and where it’s going to go. Join METER soil physicist, Dr. Doug Cobos, as he teaches the basics of this critical measurement. Learn:
- What is water potential?
- Why water potential isn’t as confusing as it’s made out to be
- Common misconceptions about soil water content and water potential
- Why water potential is important to you

Solutions to Address Osmosis and the Blistering of Liquid-Applied Waterproofi...RDH Building Science
Waterproofing membranes are widely used in the building industry as a barrier for water entry into a building enclosure. Over the past two decades, waterproofing system failure due to osmotic blistering has occurred in some protected membrane/inverted roofing assemblies. Not all waterproofing membrane assemblies are at risk for this process and the authors have developed a test protocol to establish the relative risk level of waterproofing membranes to osmosis. Using this protocol, the osmotic flow rate of SBS, hot rubberized asphalt, PMMA, EPDM, TPO, HDPE, polyurea, asphalt emulsion, asphalt-modified polyurethane, and various other 2-component cold applied membranes was measured to determine a threshold osmotic flow rate for low risk waterproofing membrane systems.
In this research, a wide range of osmotic flow rates were obtained for the various membrane types. Most asphalt-modified polyurethane membranes consistently exhibit osmotic flow rates significantly higher than the low-risk threshold of ~0.0 g/m²/day (typically 1.4 to over 20 g/m²/day) after data corrections, which results in osmotic blistering and premature membrane failures. Some polyurea and asphalt emulsion membranes have flow rates above 2.0 g/m²/day with unknown long-term performance, while most other membranes that were tested have flow rates around 0.0 g/m²/day after data corrections from control samples. To reduce the potential for osmotic blistering over concrete, it is recommended that waterproofing membranes used in inverted roofing assemblies should have an osmotic flow rate near 0.0 g/m²/day when tested using the methodology herein, an inverted wet cup vapour permeance less than that of the substrate (i.e. <0.1 US Perms on a concrete substrate), and minimal long-term water absorption.

Soil moisture is commonly defined as the amount of water contained in a unit volume of soil. The retention of moisture,
or water, in the soil and the attendant runoff from naturally occurring rainfall, snow melt, or irrigation are fundamental
processes upon which all civilization depends for food production, potable water, and navigable streams and
waterways.

Irrigation of Controlled Environment Crops—Part 4: Balancing Light, Water, an...METER Group, Inc. USA
Are you unwittingly compromising your plants?
In a controlled environment many variables affect production. But if any one of those variables gets out of balance, it can undermine your whole operation. For example, if you apply enough nutrients for high production but only enough light for low production, you’ll increase costs and limit yield. To get the most out of your crop, you’ll need to measure and balance environmental inputs correctly to get the most efficient use out of them. If you’re not measuring the right variables, fixing problems that keep you from your goals will be a shot in the dark, because you won’t know what the real problem is.
Amplify your production and efficiency
In part 4 of our popular controlled-environment webinar series, world-renowned soil physicist, Dr. Gaylon Campbell, teaches what is required to ensure all environmental variables remain balanced for the highest possible efficiency and production. Discover:

Rev up your productivity
If you’re crop steering to optimize quality and productivity, understanding nutrient concentration is critical to stressing your plants correctly. If nutrient concentrations get too low, you won’t get the production you’re paying for with the rest of your infrastructure. If the concentrations are too high—you’ll risk killing your plants.
Measure. Don’t guess.
You can’t quantify nutrient concentration just by looking at your plants or tasting the fruit. The only way to know the nutrient concentration is to measure it. Crop steering can only be done if you know the electrical conductivity (EC) of the nutrient solution in the growth substrate. In this 30-minute webinar, world-renowned soil physics expert, Dr. Gaylon Campbell discusses how to measure EC and osmotic stress to optimize crop steering for maximum yield. He’ll cover:
- Environmental control of growth and development in plants
- Electrical conductivity as a measure of nutrient concentration in the growth medium

Richard's aventures in two entangled wonderlands
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

RNA INTERFERENCE: UNRAVELING GENETIC SILENCING
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
