Taking a few slow, deep breaths significantly reduces children's physiological arousal in everyday settings, research shows. It's one of the first things parents and teachers tell a child who gets upset : "Take a deep breath." But research into the effect of deep breathing on the body's stress response has overwhelmingly ignored young children—and studies done with adults typically take place in
Saldanha Bay harbor on the west coast of South Africa has long been an important point for global shipping routes. It was also the port of entry for an unwanted stow-away: the Mediterranean mussel. The species first appeared in South Africa in the late 1980s, and has spread along the west and south coasts. It has displaced native species, increased the areas covered by mussel beds, and damaged inf
Schools aren't just where kids go to learn reading, math, science and history. The social skills they learn—like how to build and maintain relationships with peers—are also critical. This is particularly true as schools grapple with the aftereffects of school closures due to the COVID-19 pandemic.
Caves are overlooked but essential parts of the natural world. Many animals use caves for shelter and for raising their young—bats among them. Caves are often home to multiple bat species. Bats may also use different caves for specific reasons; some travel to particular selected caves, known as maternity caves, just to have their pups. This means that large populations of bats rely on a small numb
The rhizosphere is the narrow region where plant roots and the soil interact vigorously and intensive microbial metabolism occurs. The properties of rhizosphere soil are usually different from that of non-rhizosphere soil. This is called rhizosphere effects (REs).

Solid-solution organic crystals have been brought into the quest for superior photon upconversion materials, which transform presently wasted long-wavelength light into more useful shorter wavelength light. Scientists revisited a materials approach previously deemed lackluster — using a molecule originally developed for organic LEDs — achieving outstanding performance and efficiency. Their findi
To achieve global goals for biodiversity conservation, national level implementation must be significantly improved. National policy instruments need to precisely define effective actions and the actors responsible for implementation. Accountability needs to be ensured through systematic monitoring of progress. These recommendations are at the core of a 3-step framework proposed by an internationa
Cost-slashing innovations are underway in the electric power sector and could give electricity the lead over fossil-based combustion fuels in the world's energy supply by mid-century. When combined with a global carbon price, these developments can catalyse emission reductions to reach the Paris climate targets, while reducing the need for controversial negative emissions, a new study finds.
Using computer simulations, chemists have discovered how nuclear bodies called nucleoli interact with chromosomes in the nucleus, and how those interactions help the nucleoli exist as stable droplets within the nucleus.
Bacteria from the digestive system seem to have the potential to cause damage to pancreatic cells, increasing the risk of malignant tumors. Now for the first time, live bacteria from cystic pancreatic lesions that are precursors to pancreatic cancer, have been analyzed by researchers. The study can lead to prophylactic interventions using local antibiotics.
Scientists have documented the discovery of two new species of fossilized armored worms in Australia — Lepidocoleus caliburnus and Lepidocoleus shurikenus — dating from about 400 million years ago. Then, using the micro-CT imaging capabilities of the MU X-ray Microanalysis Core facility, the researchers were able to develop first-of-its-kind digital 3D-models of the species' individual armor pla

A new study has identified serpentinite — a green rock that looks a bit like snakeskin and holds fluids in its mineral structures — as a key driver of the oxygen recycling process, which helped create and maintain the sustaining atmosphere for life on Earth.
I have read articles on people activating their amygdala over a picture of someone of another skin color. Know a little bit of neuroscience but not enough. What determines the amygdala (or insular) to be activated? submitted by /u/30whyamihere [link] [comments]
In the 1960's, five teenagers boarded a rubber raft and set out a mile out to sea to skin dive. The five teenagers never came back home. Early the next morning, one of the teenagers, Brian McCleary, was found sleeping on a beach. As soon as he woke up in a naval hospital, he told everyone that he witnessed, in great detail, a fictional character, 'sea serpent' or 'Cecil the seasick sea serpent' f
Scientists from the United States and Europe announced plans Tuesday to create the biggest map of underground fungal networks, arguing they are an important but overlooked piece in the puzzle of how to tackle climate change.
Australians who are frequently involved in religion and who identify as religious are less likely to acknowledge domestic violence is an issue within their faith community, despite acknowledging it as a national issue, a new study has found.
Monsoons are continental weather events produced when intense summer sunlight heats land more than ocean. But new supercomputer simulations show that North America's only monsoon works differently. The North American monsoon, which drenches western Mexico and the American Southwest each summer, is generated when the jet stream collides with the Sierra Madre mountains, which diverts it southward an
A new decision-making framework designed by an international team of fisheries researchers can help fisheries bolster their ability to adapt to a warming world. The tool is meant to take a lot of the guesswork out of finding resilience in a time of climate change.
New research has demonstrated the significant role that an irregular body clock plays in driving inflammation in the body's immune cells, with implications for the most serious and prevalent diseases in humans.
Nature, Published online: 30 November 2021; doi:10.1038/d41586-021-03535-x Collaborators are locked in a high-stakes dispute over which researchers should be named as inventors on a key vaccine patent application.
The ADHD is strong in me and there are a number of things I'd like to learn/improve on daily. But how do I know I'm not spreading my brain too thin and wasting time? If I do a piano lesson and then a chess lesson and then a read a non-fiction book – is my brain going to get 'exhausted' and forgot/ not retain stuff from earlier in the day? Does the brain act like muscles after the gym where it nee
Want to participate in science? At the UNLV Music Lab (Principal Investigator: Erin Hannon) we study how different people respond to music, language, and the many sounds in the world. We are currently recruiting for a research study in which we will ask you questions about which sounds you like and dislike, your musical experiences and habits, and your general auditory experiences, and you will d
Researchers have created benchmarks for 100 everyday household tasks for robot assistants, creating a path for more useful agents. Robots that do everything from helping people get dressed in the morning to washing (and putting away) the dishes have been a dream for as long people have uttered the words "artificial intelligence." But, in a field where the state of the art currently rests far shor
The Chesapeake Bay Program and its partners, including the University of Michigan, released information today on the state of the 2021 Chesapeake Bay "dead zone." While last year's dead zone was the second smallest observed since 1985, this year's assessment paints a more complex picture of the bay's health.
English learners in New Jersey public schools, already facing inadequate supports and a lack of attention, missed out on critical services during the COVID-19 pandemic, according to a new report that a Rutgers faculty member helped edit.
The recent rise of anti-Asian attacks across the U.S. has galvanized the community to build newfound alliances and resilience, with advocates working to increase reporting of hate incidents and developing strategies to fight anti-Asian racism, according to a new RAND Corporation report.
About 1000 days after the Mars InSight mission deployed SEIS, the first seismometer on the red planet, researchers are analyzing new seismic data and reporting on instrument responses, using these data to plan for future planetary seismographs.
Normally, dendritic size is established prior to adolescence and then remains relatively constant into adulthood due to a homeostatic balance between growth and retraction pathways. However, schizophrenia is characterized by accelerated reductions of cerebral cortex gray matter volume and onset of clinical symptoms during adolescence, with reductions in layer 3…
Increasing habitat fragmentation leads to wild populations becoming small, isolated, and threatened by inbreeding depression. However, small populations may be able to purge recessive deleterious alleles as they become expressed in homozygotes, thus reducing inbreeding depression and increasing population viability. We used whole-genome sequences from 57 tigers to estimate individual…
Antigen-specific peripheral tolerance is crucial to prevent the development of organ-specific autoimmunity. However, its function decoupled from thymic tolerance remains unclear. We used desmoglein 3 (Dsg3), a pemphigus antigen expressed in keratinocytes, to analyze peripheral tolerance under physiological antigen-expression conditions. Dsg3-deficient thymi were transplanted into athymic mice to c
A basic principle of perception is that as objects increase in distance from an observer, they also become logarithmically compressed in perception (i.e., not differentiated from one another), making them hard to distinguish. Could this basic principle apply to perhaps our most meaningful mental representation: our own sense of self?…
The fragility index is a clinically meaningful metric based on modifying patient outcomes that is increasingly used to interpret the robustness of clinical trial results. The fragility index relies on a concept that explores alternative realizations of the same clinical trial by modifying patient measurements. In this article, we propose…
Auditory transduction is mediated by chordotonal (Cho) neurons in Drosophila larvae, but the molecular identity of the mechanotransduction (MET) channel is elusive. Here, we established a whole-cell recording system of Cho neurons and showed that two transient receptor potential vanilloid (TRPV) channels, Nanchung (NAN) and Inactive (IAV), are essential for…
Double-network gels are a class of tough soft materials comprising two elastic networks with contrasting structures. The formation of a large internal damage zone ahead of the crack tip by the rupturing of the brittle network accounts for the large crack resistance of the materials. Understanding what determines the damage…
Refining a theorem of Zarhin, we prove that, given a g-dimensional abelian variety X and an endomorphism u of X, there exists a matrix A∈M2g(ℤ) such that each Tate module TℓX has a ℤℓ-basis on which the action of u is given by A, and similarly for the covariant Dieudonné…
Despite having similar structures, each member of the heteromeric amino acid transporter (HAT) family shows exquisite preference for the exchange of certain amino acids. Substrate specificity determines the physiological function of each HAT and their role in human diseases. However, HAT transport preference for some amino acids over others is…
In natural environments, bacteria are frequently subject to conditions of nutrient scarcity, upon which they cease to grow (1). Nongrowing bacterial cells are faced with a multitude of stresses, including nutrient depletion, alterations in cellular pH, and protein damage. While such cells mount a general stress response that renders them…
The world of cryptocurrency has its own memes and slang. Its members are a dedicated community willing to endure the uncertainty and risk of the cryptocurrency investing roller coaster. Like sports fanatics, these HODL-ing risk takers like to demonstrate their passion for blockchain technology with hats, shirts, and various tchotchkes. As the holiday season arrives, we've assembled a list of cryp
Wide disagreement remains among U.S. experts who study gun policy issues, with differing opinions about how much individual policies may reduce gun violence and other harms caused by firearms, according to a new RAND Corporation report.
"Put down your phone" is a common parental phrase, the modern-day equivalent of "turn off the TV." That's because parents have long thought that staring at a screen for too long will have a detrimental effect.
When mice rest, individual neurons fire in seconds-long, coordinated cascades, triggering activity across the brain, according to new research. Previously, this was thought to be a relatively random process — single neurons firing spontaneously at random times without external stimulation.
Researchers discovered that antihistamines are associated with improved responses to immunotherapy. Their work revealed a role for the histamine receptor in suppressing T cell activation to block anti-tumor immune responses.
To push confocal imaging to an unprecedented level of performance, scientists have invented a 'kitchen sink' confocal platform that borrows solutions from other high-powered imaging systems, adds a unifying thread of 'Deep Learning' artificial intelligence algorithms, and successfully improves the confocal's volumetric resolution by more than 10-fold while simultaneously reducing phototoxicity.
A new study has found that cognitive behavioral therapy (CBT-I) prevented major depression, decreasing the likelihood of depression by over 50% as compared to sleep education therapy in adults over the age of 60 with insomnia.
This is a re-post from Yale Climate Connections by Samantha Harrington When John Boelts sows acres of cotton seed on his farm in Yuma, Arizona, he does so knowing that the fields will be free of an invasive pest called pink bollworm. For nearly a century, the small pink striped caterpillars terrorized cotton fields in the U.S. The adult bollworm, a gray moth, laid its eggs on cotton bolls, and th
A new study finds significant diversity among gorilla gut microbiomes, suggesting that what constitutes a "healthy" microbiome can vary between individuals. The findings move researchers closer to developing tools that can use the microbiome to diagnose potential health challenges for gorillas in human care. The gut microbiome refers to the ecosystem of microbial organisms that exist in the gastr
A new study finds that pesticides directly affect bee health and the effects from past exposure can carry over to future generations. The study, published in the journal Proceedings of the National Academy of Sciences , suggests that bees may require multiple generations to recover from even a single application. Bees play a critical role in agricultural ecosystems, providing pollination for many
Car tailpipes spew out molecules of ammonia, a harmful air pollutant that can lead to thousands of premature deaths every year. New research shows that vehicles may produce a lot more of these emissions than federal and state regulators have believed.
Converting newly emptied office spaces into podcast studios poses noise challenges not previously realized before hybrid offices began. Experts recommend considering location, nearby noise sources, and ways to absorb sound to make a studio effective.
Varaktig viktminskning tycks i sig skydda mot cancer, men med bra glukoskontroll blir antalet cancerfall radikalt färre. Det visar en studie från Göteborgs universitet. Att fetma är en riskfaktor för både diabetes typ 2 och flera typer av cancer är ett känt faktum. Likaså att avsiktlig viktminskning, genom exempelvis fetmakirurgi, ofta leder till att personen blir fri från diabetessymtom och uppn
Demand response (DR) programs incentivize electric grid users to consume less power during peak hours, relieving grid load and reducing CO2 emissions. However, its potential as a practical approach remains unverified. Now, scientists propose an AI-based approach to estimate the DR potential per household based on real-world user behavior, demonstrating that DR programs are beneficial for customers
Play is important for the development of complex social, emotional, physical, and cognitive skills. Play provides young individuals with a safe space to practice new behaviors without grave repercussions. While most animals engage in play, only humans engage in rule-based games. Which kinds of games people play — competitive or cooperative — may depend on their cultural background. In a new stud
A number of factors during the pandemic made it less likely that infants received their recommended vaccinations in the first months of their lives, a new study reveals. The factors include negative impacts from the pandemic during pregnancy, health care experiences, and reports of discrimination. The study serves as an indicator that a focus on vulnerable pregnant women, especially during a publ
The moon has no core dynamo magnetic field, but spacecraft detect numerous strong localized magnetic fields in the crust of the moon. Many of these magnetic anomalies are antipodal to large impact basins.
For the first time, researchers established that young fathers who have a firstborn son rather than a daughter are convicted of fewer crimes in subsequent years, and crucially that this reduction also leads to a drop in criminal convictions among peers living in the same neighborhood.
To find the right battery molecules, researchers have turned to the power of artificial intelligence to search through a vast chemical space of over a million molecules and optimize for several properties.
