A new study from the University of Georgia suggests people posting in Reddit’s r/selfharm community are likely seeking support for negative emotions. While sharing traumatic events online can be cathartic, the researchers caution that subreddits can’t provide the same type of mental health help and support face-to-face interactions and professional help can. “We don’t know the accuracy of the information that’s being shared in these communities about nonsuicidal self-injury,” ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before the appearance of the first animals. A team from the University of Geneva (UNIGE) has observed that this species forms multicellular structures that bear striking similarities to animal embryos. These observations suggest that the genetic programmes responsible for embryonic development were already present before the emergence of animal life, ...

OXFORD, Miss. – For parents of children with disabilities, finding time to focus on themselves may be difficult. However, a new study finds that the right coping strategies and resilience can significantly help manage the challenges of raising children with special needs.  That is the key finding from research published in the International Journal of Developmental Disabilities that studied families with neurodevelopmentally disabled children in Ghana to see what helps parents cultivate healthy, happy lives for themselves and their children.   “Our main interest ...

A study published in Nature by researchers at Baylor College of Medicine changes the way we understand memory. Until now, memories have been explained by the activity of brain cells called neurons that respond to learning events and control memory recall. The Baylor team expanded this theory by showing that non-neuronal cell types in the brain called astrocytes – star-shaped cells – also store memories and work in concert with groups of neurons called engrams to regulate storage and retrieval of memories. “The prevailing idea is that the formation and recall of memories only involves neuronal engrams that are activated by certain ...

UPTON, N.Y. — Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC) — a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory — to reveal subtle details about the shapes of atomic nuclei. The method, described in a paper just published in Nature, is complementary to lower energy techniques for determining nuclear structure. It will add depth to scientists’ understanding of the nuclei that make up the ...

Researchers at the University of Liverpool have developed AI-driven mobile robots that can carry out chemical synthesis research with axtraordinairy efficiency.

Mount Sinai researchers have discovered for the first time a neural mechanism for memory integration that stretches across both time and personal experience. These findings, reported in Nature, demonstrate how memories stored in neural ensembles in the brain are constantly being updated and reorganized with salient information, and represent an important step in deciphering how our memories stay current with the most recently available information. This discovery could have important implications for better understanding adaptive memory processes ...

The atoms of amorphous solids like glass have no ordered structure; they arrange themselves randomly, like scattered grains of sand on a beach. Normally, making materials amorphous — a process known as amorphization — requires considerable amounts of energy. The most common technique is the melt-quench process, which involves heating a material until it liquifies, then rapidly cooling it so the atoms don’t have time to order themselves in a crystal lattice.  Now, researchers ...

Ghent, 7 November 2024 – Scientists have uncovered how certain E. coli bacteria in the gut promote colon cancer by binding to intestinal cells and releasing a DNA-damaging toxin. The study, published in Nature, sheds light on a new approach to potentially reduce cancer risk. The study was performed by the teams of Prof. Lars Vereecke (VIB-UGent Center for Inflammation Research) and Prof. Han Remaut (VIB-VUB Center for Structural Biology). Bacteria and colon cancer Colon cancer ranks as the third most prevalent and deadliest type of cancer. Alarmingly, its incidence is rising, particularly ...

Neuroscientists have discovered brain cells that form multiple coordinate systems to tell us “where we are” in a sequence of behaviours. These cells can play out different sequences of actions, just like a music box can be configured to play different sequences of tones. The findings help us understand the algorithms used by the brain to flexibly generate complex behaviours, such as planning and reasoning, and might be useful in understanding how such processes go wrong in psychiatric ...

Some patients being treated with immune checkpoint inhibitors, a type of cancer immunotherapy, develop a dangerous form of heart inflammation called myocarditis. Researchers led by physicians and scientists at the Broad Institute of MIT and Harvard and Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham healthcare system, have now uncovered the immune basis of this inflammation. The team identified changes in specific types of immune and stromal cells in the heart that underlie myocarditis and pinpointed factors in the blood that may indicate ...

Families purchased more school lunches and breakfasts the year after the federal government toughened nutritional standards for school meals. A new University of California, Davis, study suggests that families turned to school lunches after the Obama administration initiative was in effect to save time and money and take advantage of more nutritious options. Researchers looked at the purchasing habits of nearly 8,000 U.S. households over two years — one year before and after the change in standards. The results have important implications for policymakers and researchers, but also food manufacturers and retailers, researchers said. The study, ...

A recent prospective cross-sectional study in Thailand demonstrates that multitarget stool DNA testing is highly sensitive and specific for detecting colorectal cancer (CRC) among Thai individuals. Researchers believe that this testing method could serve as a viable non-invasive alternative to colonoscopy, especially in settings where colonoscopy is less accessible or less accepted by patients. This study was conducted by BGI Genomics in 2023, in collaboration with Professor Varut Lohsiriwat’s team from the Faculty of Medicine, Siriraj Hospital, Mahidol University, Thailand. ...

Exhaled breath contains chemical clues to what’s going on inside the body, including diseases like lung cancer. And devising ways to sense these compounds could help doctors provide early diagnoses — and improve patients’ prospects. In a study in ACS Sensors, researchers report developing ultrasensitive, nanoscale sensors that in small-scale tests distinguished a key change in the chemistry of the breath of people with lung cancer. November is Lung Cancer Awareness Month. People breathe out many gases, such as water vapor and carbon dioxide, as well as other airborne compounds. Researchers ...

The team compared and analyzed the perioperative outcomes of 110 cases of robotic thymectomy using the single-port robotic system and conventional video-assisted thoracic surgery(VATS) thymectomy from November 2018 to May 2024. The results showed that all robotic thymectomy performed were successfully ...

One out of 100 people will experience a psychotic episode in their lifetime, and these usually appear in late adolescence or early adulthood. A Canada-US team consisting of Sylvain Bouix, from École de technologie supérieure (ÉTS), Martha E. Shenton and Ofer Pasternak, from the Brigham and Women’s Hospital (Harvard University), and René Kahn, from Mount Sinai Hospital (New York) has just received US $33 million in funding—the equivalent of CAD 45 million—over five years from the National Institute of Mental Health ...

PULLMAN, Wash. – An epidemiological study found that 56% of a large breeding colony of Caspian terns died from a 2023 outbreak of highly pathogenic avian influenza at Rat Island in Washington state. Since then, no birds have successfully bred on the island, raising concerns that the outbreak may have had a significant impact on an already declining Pacific-coast population. As part of the study, a team including Washington Department of Fish and Wildlife (WDFW) as well as Washington State University researchers also documented that the avian flu virus H5N1was transmitted to harbor seals for the first time in the northeastern ...

Why do mice have tails? The answer to this is not as simple as you might think. New research from the Okinawa Institute of Science and Technology (OIST) has shown that there’s more to the humble mouse tail than previously assumed. Using a novel experimental setup involving a tilting platform, high-speed videography and mathematical modelling, scientists have demonstrated how mice swing their tails like a whip to maintain balance – and these findings can help us better understand balance issues in humans, paving the way for spotting and treating neurodegenerative diseases like multiple ...

CHAMPAIGN, Ill. — Materials scientists can now use insight from a very common mineral and well-established earthquake and avalanche statistics to quantify how hostile environmental interactions may impact the degradation and failure of materials used for advanced solar panels, geological carbon sequestration and infrastructure such as buildings, roads and bridges. The new study, led by the University of Illinois Urbana-Champaign in collaboration with Sandia National Laboratories and Bucknell University, shows that the amount ...

Vitamin D during pregnancy boosts children’s bone health even at age seven Children whose mothers took extra vitamin D during pregnancy continue to have stronger bones at age seven, according to new research led by the University of Southampton and University Hospital Southampton (UHS). Bone density scans revealed that children born to mothers who were given vitamin D supplements during pregnancy have greater bone mineral density in mid-childhood. Their bones contain more calcium and other minerals, making them stronger and less likely to break. Researchers say the findings, published in The American Journal of Clinical Nutrition,   reinforce the importance of ...

The CRISPR molecular scissors have the potential to revolutionize the treatment of genetic diseases. This is because they can be used to correct specific defective sections of the genome. Unfortunately, however, there is a catch: under certain conditions, the repair can lead to new genetic defects – as in the case of chronic granulomatous disease. This was reported by a team of basic researchers and physicians from the clinical research program ImmuGene at the University of Zurich (UZH). Chronic granulomatous disease is ...
