Researchers at Yale and elsewhere previously identified a host of genetic risk factors that help explain why some veterans are especially susceptible to the debilitating symptoms of post-traumatic stress disorder (PTSD).
Nanoparticles are valuable and useful in many products, but according to a new study, they can also damage our cells. Researchers are concerned about the effect of lifelong exposure to the human organism.
New research shows SARS-CoV-2 promotes pain relief when it infects cells through a common protein receptor, neuropilin-1. The finding gives scientists a novel target for non-opioid pain therapeutics, while also offering an explanation for the unrelenting spread of COVID-19.
Through the use of two advanced audio recording technologies, a collaboration of Monterey Bay researchers has found that blue whales switch from nighttime to daytime singing when they are starting to migrate.
A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain -- which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer's Disease -- that could be targeted for new therapies. The study was published today in Science.
A new database analysis of approximately 80,000 patients shows that people with Parkinson's disease (PD) have a 30% higher death rate from COVID-19 than people without the neurodegenerative condition. The new analysis of patient data in the TriNetX COVID-19 research network conducted by University of Iowa researchers and published in Movement Disorders suggests that Parkinson's disease is an...
A new, accurate screening tool for clinical skin products has been developed which uses flatworms rather than rabbits
Physical Review X recently reported on a new optical resonator from the Technion - Israel Institute of Technology that is unprecedented in resonance enhancement. Developed by graduate student Jacob Kher-Alden under the supervision of Professor Tal Carmon, the Technion-born resonator has record-breaking capabilities in resonance enhancement.
A class of compounds used for malaria treatment also kill the intestinal parasite Cryptosporidium, a leading cause of diarrheal disease and death in children that has no cure, a multi-institution collaboration of researchers found in a new study.
Sitting atop power transformers are bushing systems that play a critical role in supplying communities with electricity. However, these objects are also susceptible to breaking during earthquakes. Once damaged, bushings can cause widespread outages and burden a state with expensive repairs.
Research has shown that the exceptional circumstances brought about by the novel coronavirus have affected the nightmares people have. The Sleep and Mind research group at the University of Helsinki employed artificial intelligence to investigate people's dreams.
Researchers at the University of Tennessee Health Science Center working with colleagues at MD Anderson Cancer Center in Houston have found that some antibodies to SARS-CoV-2, the virus that causes COVID-19, are more protective than others, when it comes to reinfection.
Four out of five people experiencing the recent loss of smell and/or taste tested positive for COVID-19 antibodies--and of those who tested positive, 40 percent did not have cough or fever, reports a new study in PLOS Medicine by Prof. Rachel Batterham at University College London and colleagues.
he songs that crickets and katydids sing at night to attract mates can help in monitoring and mapping their populations, according to Penn State researchers, whose study of Orthoptera species in central Pennsylvania also shed light on these insects' habitat preferences.
Benign breast diseases, which are non-cancerous disorders of the breast, such as lumps, are known to increase the chances of subsequent breast cancer. Now a team of Spanish researchers have found that the way BBD is detected as part of a national screening programme is an indication of which are more likely to become cancerous. The research is presented at the 12th European Breast Cancer...
A group of researchers at the University of Ottawa has been looking for ways to improve enzyme design methodologies. They developed a novel computational procedure for enzyme design that is more accurate than previous methods because it allows to approximate the intrinsic flexibility of the protein scaffold used as a template for design.
Automated analysis of breast cancer patients' routine scans can predict which women have a greater than one in four risk of going on to develop cardiovascular disease, according to research presented at the 12th European Breast Cancer Conference.
Researchers at Gladstone Institutes, in collaboration with scientists at UC San Francisco (UCSF) and the Technical University of Munich (TUM), have mapped out the networks of genes that help differentiate regulatory T cells from other T cells. Their findings could lead to immune therapies that strengthen or weaken the function of regulatory T cells.
Repeating a study conducted in 1914, scientists from the University of Plymouth have shown that species may be able to evolve and adapt to rapid climate change.
Army-funded research developed a new microwave radiation sensor with 100,000 times higher sensitivity than currently available commercial sensors. Researchers said better detection of microwave radiation will enable improved thermal imaging, electronic warfare, radio communications and radar.
A study in mice conducted by the UAB shows that social isolation worsens the effects of Alzheimer's disease, with hyperactivity levels reaching up to twice as much as in the pathology itself, and confirms an increase in the asymmetric atrophy of the hippocampus, a brain area central to memory. The study was published in a special edition of Frontiers in Psychiatry entitled Death and Mourning...
Spinal cord injury often leads to permanent functional impairment. In a new study published in the journal Science researchers at Karolinska Institutet in Sweden show that it is possible to stimulate stem cells in the mouse spinal cord to form large amounts of new oligodendrocytes, cells that are essential to the ability of neurons to transmit signals, and thus to help repair the spinal cord after...
In unraveling how a single cell develops into a complex organism, one vexing question has remained for developmental biology: How do robust patterns form in the body? An answer has now been found for the zebrafish neural tube. In this paradigm of patterned tissues, the varying stickiness of cells combined with gradients of signaling molecules is responsible for generating a robust pattern. This is...
A study revealed little effort has been made to improve older adult representation in clinical trials of new cancer drugs, even when the treatment is aimed at a disease that disproportionately affects this age group. "There is currently no incentive to establish real-world effectiveness among older adults. Older adults need a seat at the table," said Dr. Mina Sedrak, lead author, adding 2 in 5...
A mindfulness-based stress reduction course was found to benefit patients with chronic pain and depression, leading to significant improvement in participant perceptions of pain, mood and functional capacity, according to a study in The Journal of the American Osteopathic Association. Most of the study respondents (89%) reported the program helped them find ways to better cope with their pain...
