Scientists solve long-standing mystery by a whisker
Neuroscientists have experimented on mice to identify the brain region that functions beyond sensory encoding and motor encoding, potentially opening up new directions to studying the cellular and circuit mechanisms of sensory-motor transformations. The researchers report a cortical region traditionally defined as whisker motor cortex in mice is most directly related to the transformation process.
It's elemental: Ultra-trace detector tests gold purity
Unless radon gas is discovered in a home inspection, most people remain blissfully unaware that rocks like granite, metal ores, and some soils contain naturally occurring sources of radiation. In most cases, low levels of radiation are not a health concern. But some scientists and engineers are concerned about even trace levels of radiation, which can wreak havoc on sensitive equipment. The semico
Arctic warming and diminishing sea ice are influencing the atmosphere
Researchers have resolved for the first time, how the environment affects the formation of nanoparticles in the Arctic. The results give additional insight into the future of melting sea ice and the Arctic atmosphere. Until recent studies, the molecular processes of particle formation in the high Arctic remained a mystery.
Synthesizing valuable chemicals from contaminated soil
Scientists have developed a process to produce commodity chemicals in a much less hazardous way than was previously possible. The researchers report that they have been able to utilize electrolysis, i.e., the application of an electric current, to obtain chemicals known as dichloro and dibromo compounds, which can then be used to synthesize commodity chemicals.
Using science to explore a 60-year-old Russian mystery
Researchers have conducted an original scientific study that puts forth a plausible explanation for the mysterious 1959 death of nine hikers in the Ural Mountains in the former Soviet Union. The tragic Dyatlov Pass Incident, as it came to be called, has spawned a number of theories, from murderous Yeti to secret military experiments.

What we see shapes what we hear
People often move their hands up and down to 'highlight' what they are saying. Are such 'beat gestures' important for communication? Researchers created words with an ambiguous stress pattern and asked listeners what they heard (DIScount or disCOUNT?). The beat gestures people saw influenced what they heard, showing that listeners quickly integrate verbal and visual information during speech recog
Scholars reveal the changing nature of U.S. cities
New findings buck the historical view that most cities in the United States developed in similar ways. Using a century's worth of urban spatial data, researchers found a long history of urban size (how big a place is) "decoupling" from urban form (the shape and structure of a city), leading to cities not all evolving the same — or even close.
Immune system sets 'tripwire' to protect against viruses
A new study has revealed insights on the intricate, adaptive mechanisms of a protective system employed by the cells of mammalian immune systems. These defenses have evolved to set a type of tripwire that produces an immune response against attack from viruses.
Human activity caused the long-term growth of greenhouse gas methane
Decadal growth rate of methane in the atmosphere varied dramatically over the past 30 yeas with three distinct periods of slowed (1988-1998), quasi-stationary (1999-2006) and renewed (2007-2016) phases. An inverse analysis with atmospheric chemistry transport modeling explained these variations consistently. While emissions from oil and gas exploitation and natural climate events caused the slowed
Genetic analysis of symptoms yields new insights into PTSD
A new study uncovers intriguing genetic similarities between PTSD and other mental health disorders such as anxiety, bipolar disorder, and schizophrenia. The findings also suggest that existing drugs commonly used for other disorders might be modified to help treat individual symptoms of multiple disorders.
Size matters: How the size of a male's weapons affects its anti-predator tactics
When males have to fight for reproductive rights, having larger weapons such as horns gives them an edge. However, this can also limit their mobility, making them more vulnerable to predators. In a recent study, scientists demonstrated that males of a species adopt different anti-predator tactics — tonic immobility or escape — based on the size of their weapons, opening doors to a better underst

What do you think will be the dominant way of life of the future? Life form based on silicon, carbon or fusion of the two?
So, I watch in awe the advances in artificial intelligence. At this rate, I would not be surprised if machines reached general artificial intelligence before 2100. Knowing that machines never get tired or bored, and they are super fast processing information and doing work (just ask a human and a computer to write a word 1000 times , or see how learning algorithms reach a superhuman level in some
The Utopia Mirage: Universal Basic Income, Socialism, and the Future of the Global Economy.
Introduction I see a great deal of talk on this subreddit about Universal Basic Income (UBI). I'll admit to not hating the idea, since I believe that if implemented correctly it could do a great deal of good. However, after reading the comments under this post , and reading the article that the post is about, I can't help but want to speak my mind on the matter. I admire the author of the article
Saturday Night Live Is Over It
Saturday Night Live returned last night after a six-week hiatus, ready to tackle a turbulent period that included the insurrection at the Capitol, the inauguration of Joe Biden, and the second impeachment of Donald Trump—the kind of chaotic political fodder that's been a mainstay of the show for the past four years. I tuned in with a tinge of dread, expecting perhaps a dramatic send-off for Alec
Using zirconium as an additive in super-strong composite materials
Ceramic matrix composites (CMCs) are incredibly strong materials used in jet engines, gas turbines, and cutting tools for nickel superalloys. Aluminum oxide (Al2O3) is hard and chemically inert, and tungsten carbide (WC) is used as a superhard material, but past efforts to create an Al2O3-WC CMC yielded unsatisfactory results. Recently, a study by Japanese scientists shows that adding zirconium at

His appeal for us to find a means of perpetuating some memory of those who died, who we
Mars had up to 20 separate ice ages, discover scientists
Researchers find that Mars had from six to 20 distinct ice ages over 300 to 800 million years. The scientists analyzed data and high-resolution photos from Mars to reach their conclusions. The study has implications for understanding the planetary history of the Red Planet. Geologists unraveled the mysteries of Martian glaciers, concluding that the planet had up to 20 separate ice ages. The groun
Scientists discover a new pathway essential for blood formation
Scientists have discovered how a protein called Tip60 plays a vital role in the renewal of blood cells in the body. Without it, the stem cells that make new blood suffer catastrophic damage. This discovery could lead to better treatments for life-threatening blood-related diseases like leukemia.
How the brain is programmed for computer programming?
Expert computer programmers show higher proficiency in certain behavioral and attention skills than their novice peers. To identify the responsible brain regions, scientists used fMRI to analyze the brain activities of 30 programmers of different skill level, finding that seven regions of the frontal, parietal and temporal cortices in expert programmers' brains are fine-tuned for programming. The

Gendered division of labor shaped human spatial behavior
Research based on the daily movements of people living in a contemporary hunter-gatherer society provides new evidence for links between the gendered division of labor in human societies over the past 2.5 million years and differences in the way men and women think about space.
In Brazil, many smaller dams disrupt fish more than large hydropower projects
A new article quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.
Technology could upend DNA sequencing for diagnosing certain DNA mutations
Doctors are increasingly using genetic signatures to diagnose diseases and determine the best course of care, but using DNA sequencing and other techniques to detect genomic rearrangements remains costly or limited in capabilities. However, an innovative breakthrough promises to diagnose DNA rearrangement mutations at a fraction of the cost with improved accuracy.
Climate Adaptation Summit 2021
The first ever Climate Adaptation Summit (#adaptationsummit) that I have heard about took place last week, on January 25-26. I think such a summit was a step in the right direction. It was adapted to the Covid-19 situation and therefore an online virtual summit streamed on YouTube . I watched a few of the streamed sessions, and it struck me that climate change adaptation seems to be a fairly new
New 'Liquid' AI Learns Continuously From Its Experience of the World
For all its comparisons to the human brain, AI still isn't much like us. Maybe that's alright. In the animal kingdom, brains come in all shapes and sizes. So, in a new machine learning approach, engineers did away with the human brain and all its beautiful complexity—turning instead to the brain of a lowly worm for inspiration. Turns out, simplicity has its benefits. The resulting neural network
The Other Tiger
Jorge Luis Borges was a poet, but he was also a dreamer of wild fiction, a thoughtful essayist, and—in all of his works—a philosopher. He was always pulling at the threads of perspective and reality, questioning his own point of view. In "," he marvels at the power of the creature in his mind's eye, envisioned with such detail that he writes about the bony structure / that quivers under the glowi
Is it possible to change a chicken's sex before it hatches?
Billions of unwanted male chicks are slaughtered by the farming industry. Now a startup claims to have found a surprising solution to the problem The eggs we eat have a hidden cost. About 7bn male chicks are killed worldwide every year to produce them. Farmers need to replenish their supply of egg-laying hens but, by nature, half the chicks that hatch are male and growing them for meat is unecono
The Colleges That Took the Pandemic Seriously
U ntil vaccines against COVID-19 are available to all, the public will need two things: a reason for hope and a vision of how to live more safely and productively in the meantime. For both, Americans can look to the examples set by a number of colleges and universities—a surprising turn, perhaps, given the widespread anxieties that these institutions' reopening in the fall created. Since last sum

Resources for an RL Researcher
Hi all, I'm currently a PhD student in reinforcement learning where I focus on computational methods for agents to learn sequential decision making problems (think: a robot learning how to pick up blocks) and am interested in how to get them to transfer the skills they learn in 1 environment to another. Naturally, how humans or animals are able to do this type of transfer seamlessly is of interes
Is it possible to get hired as a programmer/data analyst in a lab after undergrad? What skills should I build?
"Wet" neuroscience labs (e.g. those employing techniques from biochemistry) will probably not hire an undergrad for this sort of position since a Master's/PhD is usually where students learn the skills used in those labs But I'm a compsci undergrad and I already know a fair amount of neuroimaging and computational tools (python, stats+machine learning, FSL, fMRIprep). These seem like pretty in-de
