Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

5 Public speaking tips from TED - Visualized summarySpeakerHub
From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world.
With over one billion views in a year, it’s no wonder that so many speakers are looking to TED for ideas on how to share their message more effectively.
The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage.
Whether you are gearing up to get on a TED stage yourself, or just want to master the skills that so many of their speakers possess, these tips and quotes from Chris Anderson, the TED Talks Curator, will encourage you to make the most impactful impression on your audience.

2.Anatomy (Cell.pptx)
1. What is a cell?
1. A cell is the smallest unit of life. Cells are often called the "building blocks
of life". The study of cells is called cell biology, cellular biology, or
cytology. Cells consist of cytoplasm enclosed within a membrane, which
contains many biomolecules such as proteins and nucleic acids.
2. In biology, cell is the basic membrane-bound unit that contains the
fundamental molecules of life and of which all living things are composed.
... These cells cooperate with other specialized cells and become the
building blocks of large multicellular organisms, such as humans and other
animals
3. The smallest structural and functional unit of an organism, which is
typically microscopic and consists of cytoplasm and a nucleus enclosed in a
membrane.
2. पेशी म्हणजे काय?
• पेशी हे सजीव प्राणयाांचे एक मुलभूत व सांरचनात्मक एकक आहे.
पेशीच्या आधारे सवव जीवनक्रिया घडून येतात.
• Cell is the smallest basic and organized unit of a living organism.
• १६६५- रॉबर्व हुक या इांग्रज शास्त्रज्ञाने सूक्ष्मदशवकाच्या खाली
वनस्त्पती पेशी ननरीक्षण क
े ले असता त्याला त्याचा आकार एका
मधमाशीच्या पोळ्या सारखा आढळला.
• १८३१- रॉबर्व ब्राऊन याने पेशीत क
ें द्रकाचे अस्स्त्तत्व माांडले
• १८३९- एम. जे. शेल्डन आणण थिओडोर याांनी सवव सजीव
पेशीांपासून बनलेले असतात आणण पेशी हा सजीवाांचा पायाभूत
घर्क आहे हा ससदधाांत माांडला.
• १८८५- आर. ववरशॉ याांनी पेशीांचा जन्म पूवी अस्स्त्तत्वात
असलेल्या पेशीांमधुनच होतो हा ससदधाांत माांडला.
3. Types of cells
• There are two types of cells:
• Plant cell
• Animal cell
8. 1. Cell Membrane:
The cell membrane is the outer coating of the cell and contains the cytoplasm,
substances within it and the organelle. It is a double-layered membrane composed
of proteins and lipids. The lipid molecules on the outer and inner part (lipid
bilayer) allow it to selectively transport substances in and out of the cell.
2. Endoplasmic Reticulum:
The endoplasmic reticulum (ER) is a membranous structure that contains a
network of tubules and vesicles. Its structure is such that substances can move
through it and be kept in isolation from the rest of the cell until the manufacturing
processes conducted within are completed. There are two types of endoplasmic
reticulum – rough (granular) and smooth (agranular).
A) The rough endoplasmic reticulum (RER / granular ER) contains a combination of proteins
and enzymes. These parts of the endoplasmic reticulum contain a number of ribosomes giving
it a rough appearance. Its function is to synthesize new proteins.
B) The smooth endoplasmic reticulum (SER / agranular ER) does not have any attached
ribosomes. Its function is to synthesize different types of lipids (fats). The smooth ER also
plays a role in carbohydrate and drug metabolism.
3. Golgi Apparatus:
The Golgi apparatus is a stacked collection of flat vesicles. It is closely associated with the
endoplasmic reticulum in that substances produced in the ER are transported as vesicles and
fuses with the Golgi apparatus. In this way, the products from the ER are stored in the Golgi
apparatus and converted into different substances that are necessary for the cell’s various
functions.

21. पेिींसंदिाात काही महत्वाचे मुद्दे
• सवा सजीव हे एक क्रकं वा जास्त पेिीं पासून बनलेले आहेत.
• पेिी प्रचर्नांपासून बनलेल्या आहेत.
• अनेक पेिी शमळून उती / पेिीसमूह बनवतात. त्यापासून अवयव तयार
होतात.
• पवपवध प्रकारच्या पेिी असतात आणि त्यांचे काया ठरलेले असते.
• काही पेिी संपूिा िरीरात हालचाल करतात (रतत पेिी) तर काही स्नायू,
हाडे यांना धरून असतात.
• पेिी मृत पाविे आणि त्यांच्या जागी नवीन पेिी जागा घेिे ही प्रक्रक्रया
ननयशमत चालते.
• त्वचेच्या पेिींची झीज लवकर होते आणि ते मृत पावतात. परंतु त्यांची
पुनननाशमाती अनतिय लवकर होते.
• सवाात मोठी पेिी ही चेता पेिी आहे.( motor neuron) 4.5 ft.
• लाल रतत पेिी या संपूिा िरीरात रतत प्रवाद्रहत करण्याचे काया करतात
आणि त्यांची ननशमाती हाडांच्या मगज मध्ये (bone marrow) होत असते.
• िरीरात पवपवध पेिी जरी असल्या तरी त्यांचे घटक सारखेच असतात.

22. Cell division (पेशी ववभाजन)
• Cell division is the process by which a cell, called the parent cell, divides into two
cells, called daughter cells. When the cell divides, everything inside it divides
also. The nucleus and the chromosomes divide, and the mitochondria divide
also.
• या प्रक्रियेमध्ये प्रमुख/ पालक पेशीचे दोन समान पेशीांमध्ये ववभाजन होते.

• Cell division is the basis for all forms of organismal reproduction. To reproduce in
order to replicate or replace dead cells.
• पेशी ववभाजन हे सवव प्रकारच्या सजीवाांच्या पुनरुत्पादनचा आधार आहे. मृत
पेशीांच्या जागी नवीन पेशी ननमावण होऊन कायव सुरळीत चालणयासाठी पेशी
ववभाजन होत असते.
• Single cells organisms divide to reproduce. Cell division in multicellular
organisms produces specialized reproductive cells such as egg and sperm.
• In order a cell to divide, the genome must also divide. So in all types of cell
division in all organisms DNA replication precedes cell division.
• पेशी ववभाजन होणयासाठी सवव प्रकारच्या पेशीांमध्ये आधी गुणसूराांचे गुणाांकन होते
मग ववभाजन होते. यादरम्यान दोन स्त्वतांर क

• Cell division can be grouped into sexual and asexual division.
• पेशी ववभाजन लैंथगक तसेच/ क्रकां वा अलैंथगक पदधतीने होते.
23. Types of cell division in animal cell
• There are two types of cell division: mitosis and meiosis. Most of the time when
people refer to “cell division,” they mean mitosis, the process of making new body
cells. Meiosis is the type of cell division that creates egg and sperm cells.
24. Mitosis and meiosis has some phases in common. Prophase,
Metaphase ,Anaphase and Telophase are four main phases.
25. Stages of the cell cycle
• To divide, a cell must complete several important tasks: it must
grow, copy its genetic material (DNA), and physically split into two
daughter cells. Cells perform these tasks in an organized,
predictable series of steps that make up the cell cycle. The cell cycle
is a cycle, rather than a linear pathway, because at the end of each
go-round, the two daughter cells can start the exact same process
over again from the beginning.
• In eukaryotic cells, or cells with a nucleus, the stages of the cell
cycle are divided into two major phases: interphase and the mitotic
(M) phase.
• During interphase, the cell grows and makes a copy of its DNA.
• During the mitotic (M) phase, the cell separates its DNA into two
sets and divides its cytoplasm, forming two new cells.
