Researchers at the University of Michigan have illuminated a complete sensory pathway showing how the skin communicates the temperature of its surroundings to the brain. This discovery, believed to be the first of its kind, reveals that cool temperatures get their own pathway, indicating that evolution has created different circuits for hot and cold temperatures. This creates an elegant solution for ensuring precise thermal perception and appropriate behavioral responses to environmental changes, said Bo Duan, senior author of the new study. "The skin is the body's ...

The largest genetic analysis of stuttering has demonstrated a clear genetic basis for the speech disorder, highlighting neurological pathways of risk. The study, published July 28 in the journal Nature Genetics, used data representing more than 1 million individuals who had their DNA analyzed by the company 23andMe Inc.  The findings point to 57 distinct genomic loci associated with stuttering and suggest a shared genetic architecture of stuttering with autism, depression and musicality. The results provide a foundation for additional research that could lead to earlier identification or therapeutic advances in stuttering. More broadly, improving understanding of the causes ...

Researchers at the University of Birmingham have developed a powerful new method to detect harmful blue-green algae in freshwater lakes. Their method, which involves advanced mass spectrometry technology, can identify toxin producing blue-green algae before they become damaging in recreational waters and pose threat to public health. Blue-green algae (scientifically named as cyanobacteria) are micro-organisms commonly found in ponds, lakes, and oceans worldwide. In optimum growth conditions, they can form huge “blooms” that appear like green slime covering the surface of the water. Although these blooms are extremely ...

Scientists at the University of California, Davis, used artificial intelligence to help plants recognize a wider range of bacterial threats — which may lead to new ways to protect crops like tomatoes and potatoes from devastating diseases. The study was published in Nature Plants.  Plants, like animals, have immune systems. Part of their defense toolkit includes immune receptors, which give them the ability to detect bacteria and defend against it. One of those receptors, called FLS2, helps plants recognize flagellin — a protein in the tiny tails bacteria use to swim. But bacteria are sneaky and constantly ...

Toronto, Canada – A new study of 3,500 Canadians aged 55 and older revealed a strong association between early childhood adversities and depression. Experiencing physical abuse in childhood was linked to a threefold increase in the likelihood of lifetime depression, while exposure to sexual abuse or parental domestic violence more than doubled the risk. The University of Toronto research was published recently in Archives of Gerontology and Geriatrics Plus. “Our findings shine a light on how trauma in the earliest years can echo through decades, shaping patterns of mental health and well-being,” says the first author, Megha Goel, a doctoral student at the University ...

Immersing in virtual reality (VR) nature scenes helped relieve symptoms that are often seen in people living with long-term pain, with those who felt more present experiencing the strongest effects. A new study led by the University of Exeter, published in the journal Pain, tested the impact of immersive 360-degree nature films delivered using VR compared with 2D video images in reducing experience of pain, finding VR almost twice as effective.   Long-term (chronic) pain typically lasts more than three months and is particularly difficult to treat. The researchers simulated this type of pain in healthy participants, ...

Ministry of Health, and the University of British Columbia (UBC) Digital Emergency Medicine Unit has worked together to build and grow a network of virtual services to support patients, physicians, and health care providers in rural communities. Initiated in March 2020, the RTVS network is publicly funded and designed to ...

People with dementia are diagnosed an average of 3.5 years after symptoms are first noticed, or even longer (4.1 years) for those with early-onset dementia, finds a new study led by UCL researchers. The study, published in the International Journal of Geriatric Psychiatry, is the first systematic review and meta-analysis of global evidence examining time to diagnosis in dementia. The researchers reviewed data from 13 previously published studies which took place in Europe, US, Australia and China, reporting data on 30,257 participants. The research team was investigating the average interval between ...

MADISON — When a multimillion-dollar extraterrestrial vehicle gets stuck in soft sand or gravel — as did the Mars rover Spirit in 2009 — Earth-based engineers take over like a virtual tow truck, issuing a series of commands that move its wheels or reverse its course in a delicate, time-consuming effort to free it and continue its exploratory mission.  While Spirit remained permanently stuck, in the future, better terrain testing right here on terra firma could help ...

In the United States, immigration status has long created hierarchies within our society, where some can participate fully in public life, while others are excluded. These divisions have serious consequences for our communities, including when it comes to public health. A research project led by the University of California, Santa Cruz recently uncovered a particularly alarming example of this effect by looking back on excess deaths in California throughout the course of the COVID-19 pandemic.  Alicia ...

A new material developed by researchers from University of Toronto Engineering could offer a safer alternative to the non-stick chemicals commonly used in cookware and other applications.  The new substance repels both water and grease about as well as standard non-stick coatings — but it contains much lower amounts of per- and polyfluoroalkyl substances (PFAS), a family of chemicals that have raised environmental and health concerns.  “The research community has been trying to develop safer alternatives to PFAS for a long time,” says Professor Kevin ...

Most people envision vibration on a large scale, like the buzz of a cell phone notification or the oscillation of an electric toothbrush. But scientists think about vibration on a smaller scale—atomic, even.  In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois at Urbana-Champaign have used advanced imaging technology to directly observe a previously hidden branch of vibrational physics in 2D materials. Their findings, published in Science, confirm the existence of a previously unseen class ...

The Large Hadron Collider (LHC) is tough on electronics. Situated inside a 17-mile-long tunnel that runs in a circle under the border between Switzerland and France, this massive scientific instrument accelerates particles close to the speed of light before smashing them together. The collisions yield tiny maelstroms of particles and energy that hint at answers to fundamental questions about the building blocks of matter. Those collisions produce an enormous amount of data — and enough radiation to scramble the bits and logic inside almost any piece ...

The global scuba diving tourism industry generates up to around 20 billion USD per year, finds a study publishing July 25 in the Cell Press journal Cell Reports Sustainability. This revenue helps boost local economies by employing local people and supports marine conservation initiatives both by raising funds and increasing public awareness.  “Scuba diving is not a fringe hobby,” says lead study author Anna Schuhbauer of the University of British Columbia. “It is a multibillion-dollar pillar of the economy that can channel tourists’ dollars straight into coastal communities and ocean protection.”  Recent studies ...

Imagine your immune cells could be modified to attack any kind of cancer. T cell receptor (TCR) therapy has the potential to one day become a universal cancer treatment. But there are risks. Similarities between cancerous and healthy cells can affect the body’s immune response, causing T cells to attack unintended targets. TCR therapy needs laser focus to prevent friendly fire. New and curiously named AI developed at Cold Spring Harbor Laboratory (CSHL) could provide just that. How does it work, and why do we need AI for the job? In biology, cells announce their state by displaying peptides on their surface. These ...
