Some Ways Deep Sea Creatures Survive in Deep Water
Some deep-sea creatures like snailfish can survive in extreme depths by producing a chemical called TMAO that shields proteins from breaking down under intense pressure. They also have smaller, more flexible bones and cartilage to help them remain buoyant in the high-pressure environment. Most organisms cannot survive over 27,000 feet deep where the water pressure is over 800 times greater than atmospheric pressure and would crush gas bladders.

New Species of Beetle Discovered in Poland
Nature enthusiast Valerie Varnuska is a resident of Westbury, NY. Given her interest in nature, Valerie Varnuska enjoys learning about several related subjects, including paleontology.
When scanning fossilized coprolite of a dinosaur relative that lived during the Triassic period in modern-day Poland, paleontologists discovered a new species of ancient beetle. This beetle was found using synchrotron microtomography, a method that is similar to how amber insects are scanned.
Synchrotron microtomography uses 3D technology that shows a high level of resolution and contrast so internal structures in fossils are more easily identified. Thanks to this detailed technology, the researchers saw the insect’s body, something that likely would have gone unnoticed using other scanning options.
Named Triamyxa coprolithica, the new beetle is a semiaquatic specimen that belongs to the suborder Myxophaga in the daily Triamyxidae. It most likely lived in humid environments and was eaten by Silesaurus opolensis. Since Silesaurus opolensis was omnivorous, it’s unlikely that the beetle was its main source of food. Rather, it’s believed that it was simply part of its diet.
Mushrooms - Nature’s Overlooked Heroes
A resident of the Westbury, NY, area, Valerie Varnuska maintains a wide range of interests. Passionate about the arts and nature, Valerie Varnuska loves spending time outdoors and enjoying the natural wonders.
Mushrooms are one of nature’s most commonly overlooked benefactors. These organisms are extremely diverse and hold several different roles in natural functions. However, they cannot synthesize their own food from sunlight like plants can. This is because mushrooms lack chlorophyll. Instead, they derive their energy from other sources, like decaying organic matter.
Species that get energy by breaking down organic matter are known as saprophytes. Most species that grow on rotting wood or lawns are saprophytes. These types of mushrooms get their energy from decomposition, digesting the decaying organic matter that is around them while simultaneously feeding themselves and returning important nutrients to the soil.
There are also symbiotic mushrooms that grow on the forest floor near the roots of trees. The mushrooms and trees exchange nutrients via mycorrhiza and provide one another with nutrients that they cannot extract or synthesize on their own. Generally, the trees provide symbiotic mushrooms with sugar compounds, while the mushrooms share water and minerals extracted from the soil.
It’s important to note that some mushrooms are parasitic. In most cases, these species are microscopic, but they will either attack a healthy host or hasten the death of an unhealthy one.
Homo Erectus Fossil Unearthed in South Africa
A Westbury, NY-based nature enthusiast, Valerie Varnuska enjoys a variety of outdoor activities. Valerie Varnuska is also fascinated by the idea of connecting the present with the past. She keeps up with the latest news and advancements in paleontology.
Paleontology studies the history of life on earth as based on fossils. Recently, fossil remains were unearthed 40 kilometers north of Johannesburg in South Africa. Further arrangements of the fragments revealed one of the earliest known skulls of one of the earliest humans to walk the planet, the Homo erectus. Carbon dating of the fossil revealed an age of two million years old. The skull belongs to a child aged between 2 and 3 years at the time of death.
Today, Homo erectus fossils are rarely seen and exist only in puzzling fragments. Juvenile skulls are more susceptible to damage over time, which makes these types of discoveries remarkably rare. It is also more challenging to procure sufficient fragments to piece together into an intact skull.
The location in which the Homo erectus skull was found established a knowledge base that suggests a relationship between Homo erectus and other types of humans in South Africa. The findings were published in the International Journal of Science.
Analysis of Tyrannosaurus Rex Fossil Model Changed Scientists Belief
Based in Westbury, NY, Valerie Varnuska is a nature lover and enjoys exploring the natural world. Valerie Varnuska is also interested in astronomy and paleontology. Paleontology involves the study of the evolution of life on earth via the use of fossils.
Fossils of Tyrannosaurus rex revealed that the extinct apex predators possessed extremely strong bites, which earned T. rex a long-standing position as one of the world's most dangerous predators in history. According to scientists, T. rex had an optimum bite force of 12,000 pounds, which would be a powerful amount of force even for their large skull. In the past, scientists wondered how the predator managed to exert that amount of force without breaking its skull. They assumed that the T. rex’s Skull might have similar flexibility with the skulls of modern birds and reptiles, which would have manipulated the shape of the jaw when it crunches its teeth.
In 2019, the result of a study conducted at the University of Missouri suggested that T. Rex's jaw was actually stiff and fused in contrast to previous belief. In the study, scientists analyzed how the jaws of two modern relatives of T. rex worked when the predators chewed. The study concludes that the jaws of T. Rex were probably tightly fused, making the skull significantly rigid and indestructible by the tremendous force of its bite.
Three Trees That Offer Medicinal Benefits

Shrinking Stars Cause the Largest Explosions
Situated in the area of Westbury, NY, Valerie Varnuska is a nature enthusiast. During her free time, Valerie Varnuska enjoys relaxing in natural settings such as the beach. She is also fond of studying astronomy.
Supernovas cause some of the biggest explosions, with each blast showering extreme brightness and setting off random motions of gases in the darkness of space. While supernovas are caused by various events, a well-understood explanation for many observed supernovae in astronomy is a dying star.
Stars, including the sun, are nuclear power reactors in space that fuse atoms of core matter and convert them into energy (heat and light). At the centers of massive stars, heat generates pressure which counteracts the effects of gravity and stops stars from collapsing. Extreme gravity tries to squeeze the stars into the tiniest possible bits, while outward pressure prevents this. When a star burns up all its nuclear fuel, which will eventually occur at some point in time, it cools off, and pressures drop, resulting in inevitable squeezing by gravity.
These collapses occur at rapid speeds, triggering large shock waves. Shock waves cause the outer parts of the star to explode into an expanding cloud of hot gases. However, at the star's core, gravity would have squeezed matter into the densest known objects in the universe known as black holes. Black holes are only created when the exploding star is at least 10 times the size of our sun.
Cayman Island Green and Loggerhead Sea Turtle Populations Recovering
Westbury, New York area resident Valerie Varnuska enjoys diverse personal interests, including cooking and performing arts. Valerie Varnuska spends time walking outdoors and learning about nature.
ScienceDaily recently reported on a nature-related research study completed by the Cayman Islands Department of Environment and the University of Exeter on sea turtle populations in the Cayman Islands. The study, which took place from 1998 to 2019, showed that loggerhead and green turtle populations, which were nearing extinction at the start of the research initiative, are now growing.
The number of loggerhead and green turtles on the islands has increased due to captive breeding programs and strategies that help protect the turtles. For example, illegal turtle hunting was reduced due to conservation officers patrolling nesting beaches, and restrictions were implemented to prevent the activities of a turtle fishery.
Loggerhead and green turtle populations are still lower than normal compared to historical records indicating the number of animals in the islands. Prior to the early 1800s, the Cayman Islands were home to the largest number of nesting sea turtles in the world.
Simple Tips for Observing the Moon with a Telescope
Valerie Varnuska from Westbury, New York enjoys nature and watching the night sky to learn astronomy. The document provides tips for using a telescope to observe the moon, including reducing light entering the telescope, using a lunar map to identify features, and viewing the moon when it is half-illuminated shortly after the first quarter phase.
The Ecological Recovery of the Former Island of Rats
Based in the Westbury, NY area, Valerie Varnuska appreciates the environment around her and enjoys spending time outside doing activities such as walking and stargazing. A science enthusiast, Valerie Varnuska likes to learn about nature in the Westbury, NY, area, and around the globe.
Nature has a powerful ability to restore itself to natural ecological balance under the right conditions, as was proven on the former Island of Rats. Located in the Aleutian archipelago of Alaska, the island was once called the Island of Rats due to its high population of rats. The rodents were unintentionally introduced to the area by shipwrecks and occupancy during World War II.
The rats thrived and seriously disturbed the natural ecological balance of the island by threatening native species. For example, they fed on shorebirds and their offspring, resulting in an increase in the population of herbivorous seashore invertebrates, which were the food source of the birds.
In 2008, a conservation effort carried out by Island Conservation, the US Fish and Wildlife Service, and The Nature Conservancy eradicated the rats. Today, the island, now called Hawadax Island, has shown remarkable recovery. Its native species have re-established their populations and the island’s food chain has returned to a normal state.
Phytoncides May Be Key to the Health Benefits of Nature
Westbury, New York area’s Valerie Varnuska pursues a number of outdoor hobbies. Valerie Varnuska appreciates the mental and physical benefits of spending time in nature.
The health benefits of spending time in nature are well-documented, although the reasons behind the benefits are less clear. According to research from Qing Li, a physician at Japan’s Nippon Medical School Hospital and the president of the Japanese Society of Forest Medicine, at least some of the benefits of spending time in nature can be attributed to phytoncides, which are released from trees and plants into the air.
These antibacterial and antimicrobial substances help fight disease and protect plants from harmful organisms. When people spend time in nature, we inhale phytoncides.
In several studies, phytoncides have shown to improve health, boost immune function, reduce stress hormone levels, and increase the production of anti-cancer proteins. Moreover, exposure to phytoncides helped subjects relax and experience improved moods.
Tips for Beginning Stargazers
Valerie Varnuska enjoys stargazing as a hobby from her home in Westbury, NY. The document provides tips for improving the stargazing experience, including using a star chart to identify constellations, networking with other stargazers to share observations, and being consistent with a stargazing schedule to develop knowledge of the night sky over time.
A Unique Bone Structure Supported Large Dinosaur Frames
Valerie Varnuska is a longtime resident of the Westbury, New York, area who regularly explores natural destinations in the local region. Attracted to diverse disciplines in the sciences, Valerie Varnuska considers paleontology one of her major areas of interest.
A recent Southern Methodist University research project involving paleontologists, as well as biomedical and mechanical engineers, uncovered the way in which dinosaur skeletons were able to supported larger loads than mammals.
Given their massive size, the largest dinosaurs experienced major gravitational loads on their skeletons. One unique aspect of dinosaurs was the composition of their trabecula, a spongy bone. In contrast to birds and mammals, the trabecular bone did not increase in thickness as dinosaur species evolved larger. Instead, the spongy bone’s density increased.
This represented a weight-saving adaptation that accommodated the massive skeletal structures of large species such as hadrosaurs. CT scans combined with engineering failure theories have explained this phenomenon, and a greater understanding of trabecular architecture mechanics has provided insights into lightweight and dense structure design.
Study - Ocean Biodiversity Remained Constant through Millions of Years
Hiking affords Valerie Varnuska of Westbury, New York, the time to interact and appreciate nature. Her fascination with nature makes Valerie Varnuska curious about the scientific discipline studied by paleontologists.
A recent paleontological study challenged the belief that marine biodiversity has “continuously changed” over the past 200 million years. A research team from the University of Birmingham’s School of Geography, Earth, and Environmental Sciences used fossil data from the past two centuries to conclude that marine biodiversity has remained constant throughout the past 540 million years.
Previous studies of marine animal diversity have emphasized estimates of how global diversity has changed over time. In the University of Birmingham study, the research focused on regional spaces with fossil records of known times and places.
By comparison, geographic regions of similar sizes showed that marine animal diversity has changed over time and space. This localized approach also allowed researchers to look at the influence of other environmental factors.
Three Ways of Connecting With Nature When Indoors
Valerie Varnuska, a resident of Westbury, NY, firmly believes that connecting with nature fosters good health and wellness. When she can, Valerie Varnuska frequently spends time outdoors hiking..
While being outdoors reduces muscle tension, improves focus, and lowers heart rate, there are certain situations when getting outside is not an option. Fortunately, whether you’re home-bound due to weather, sickness, or any other reason, you can still connect with nature in the following ways:
Look at nature scenes
It may not seem like it, but looking at nature scenes does wonders for decreasing stress levels and boosting compassion, according to a study in the International Journal of Environmental Research and Public Health. This is likely due to the fact that viewing pictures of nature activates the parasympathetic nervous system, thus helping the body calm down.
Grow an indoor garden
There are plenty of plants that you can successfully grow indoors, from succulents to sweet potatoes. If you find yourself unable to enjoy nature outdoors, you can easily bring nature indoors by creating a terrarium or small garden at home. Having these plants in your home increases your attention and reduces both anxiety and stress.
Listen to nature sounds
Similar to looking at scenes of nature, listening to sounds from nature also has a relaxing effect on people. In fact, nature sounds reduce people’s stress, muscle tension, and heart rates more than listening to silence or classical music. Further, these benefits were seen after only about six minutes of listening to nature sounds.
Paleontology as a Profession
Valerie Varnuska lives in Westbury, New York and enjoys visiting the American Museum of Natural History in New York City, her favorite museum. Paleontologists play a key role in creating exhibits for the museum by studying fossils to understand evolution and the history of life on Earth. Those in this profession can specialize in areas like microfossils, plants, or human fossils and typically work as researchers or professors, publishing their findings.
How to Connect with Nature and Become More of a Conservationist
Valerie Varnuska enjoys the arts and nature. She spends her leisure time enjoying scenic areas around Westbury, NY. To connect with nature and become a conservationist, one can take a family hike on a local trail or visit a nature preserve to learn about the plants and wildlife. As you spend more time outdoors, you may feel motivated to join a conservation group or help with local conservation efforts through social media.
World’s Smallest Monkey Fossil Discovered in Peru
A team of researchers in Peru uncovered the 18-million-year-old tooth fossil of Parvimico materdei, one of the smallest monkey species to have existed. From this single tooth fossil, scientists were able to determine that this ancient monkey species likely weighed less than the modern pygmy marmoset and had a diet consisting primarily of fruit and insects. The discovery helps shed light on the evolution of monkey species in South America.

It may not seem like it, but looking at nature scenes does wonders for decreasing stress levels and boosting compassion, according to a study in the International Journal of Environmental Research and Public Health. This is likely due to the fact that viewing pictures of nature activates the parasympathetic nervous system, thus helping the body calm down.
Grow an indoor garden
There are plenty of plants that you can successfully grow indoors, from succulents to sweet potatoes. If you find yourself unable to enjoy nature outdoors, you can easily bring nature indoors by creating a terrarium or small garden at home. Having these plants in your home increases your attention and reduces both anxiety and stress.
Listen to nature sounds
Similar to looking at scenes of nature, listening to sounds from nature also has a relaxing effect on people. In fact, nature sounds reduce people’s stress, muscle tension, and heart rates more than listening to silence or classical music. Further, these benefits were seen after only about six minutes of listening to nature sounds.
Paleontology as a Profession
Valerie Varnuska lives in Westbury, New York and enjoys visiting the American Museum of Natural History in New York City, her favorite museum. Paleontologists play a key role in creating exhibits for the museum by studying fossils to understand evolution and the history of life on Earth. Those in this profession can specialize in areas like microfossils, plants, or human fossils and typically work as researchers or professors, publishing their findings.
How to Connect with Nature and Become More of a Conservationist
Valerie Varnuska enjoys the arts and nature. She spends her leisure time enjoying scenic areas around Westbury, NY. To connect with nature and become a conservationist, one can take a family hike on a local trail or visit a nature preserve to learn about the plants and wildlife. As you spend more time outdoors, you may feel motivated to join a conservation group or help with local conservation efforts through social media.
World’s Smallest Monkey Fossil Discovered in Peru
A team of researchers in Peru uncovered the 18-million-year-old tooth fossil of Parvimico materdei, one of the smallest monkey species to have existed. From this single tooth fossil, scientists were able to determine that this ancient monkey species likely weighed less than the modern pygmy marmoset and had a diet consisting primarily of fruit and insects. The discovery helps shed light on the evolution of monkey species in South America.

This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.
