One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new study. As a result, the North Atlantic could be flooded with freshwater which would weaken the global ocean circulation. Read more ›

New findings indicate that while the rate of marathon runners who suffer cardiac arrests remained unchanged, their chance for survival is twice what it was in the past. Now, far fewer marathon runners who suffer cardiac arrest are dying of it. Read more ›

Be it sensors, cameras, or displays: Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, multi-functional solutions. Researchers have now developed an optical component that enables highly efficient light control at steep angles of incidence, overcoming previous limitations. Read more ›

Investigators have uncovered how resistance to chemotherapies may occur in some cancers. Researchers focused on a pathway that harnesses reactive oxygen species (ROS) to kill cancer cells. The study found that mutations to VPS35, a key player in this pathway, can prevent chemotherapy-induced cell death. These results could help pinpoint treatment-resistant tumors. Read more ›

A new study found that over half of US adults experienced some form of discrimination, and individuals with high exposure to discrimination have more than five times the chances of screening positive for depression, and five times the chances of screening positive for anxiety. Compared to adults who do not experience discrimination, adults who do experience this mistreatment have nearly nine times the odds of screening positive for both depression... Read more ›

Cold water immersion for seven days significantly improves cellular resilience and autophagic function, helping cells manage stress better. This adaptation could enhance health and longevity, potentially preventing diseases and slowing aging at a cellular level. Read more ›

Novel artificial neurons learn independently and are more strongly modeled on their biological counterparts. A team of researchers has programmed these infomorphic neurons and constructed artificial neural networks from them. The special feature is that the individual artificial neurons learn in a self-organized way and draw the necessary information from their immediate environment in the network. Read more ›

Weasels are often difficult to capture on camera, making it hard for conservationists to track their population numbers. This study aimed to determine the best material to use as bait for camera traps when studying the weasels. Researchers found that red meat worked better than other options, especially when supplemented with scent oils. Read more ›

Roughly one out of three women ages 14-49 in the United States develop a vaginal bacterial imbalance known as bacterial vaginosis (BV) during their lifetime. BV is characterized by unpleasant odors, and potentially painful side effects, as well as the risk of associated health issues later in life. More than half of the patients who seek medical care do not respond to the first-line treatment, the antibiotic metronidazole, leading to... Read more ›

Clothes that can mimic the feeling of being touched, touch displays that provide haptic feedback to users, or even ultralight loudspeakers. These are just some of the devices made possible using thin silicone films that can be precisely controlled so that they vibrate, flex, press or pull exactly as desired. And all done simply by applying an electrical voltage. Read more ›

Leveraging the power of AI and machine learning technologies, researchers developed a more effective model for predicting how patients with muscle-invasive bladder cancer will respond to chemotherapy. The model harnesses whole-slide tumor imaging data and gene expression analyses in a way that outperforms previous models using a single data type. Read more ›

Scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more efficiently the tasks are completed. Armed with this information, physicians may soon be able to develop more precise treatment strategies for neurological and psychiatric disorders. Read more ›

Why do some plants thrive in specific regions but not in others? A study explores the factors shaping plant distributions and how these patterns have changed over millions of years. Analyzing nearly 270,000 seed plant species worldwide, the research highlights the roles of environmental conditions and dispersal barriers in influencing global plant diversity. Read more ›

Researchers show that the immune system can recognize and control the latent stage of the parasite Toxoplasma gondii, a finding that can inform the study of latency in other infections of the nervous system. Read more ›

Researchers have created a way to see your family tree as a movie rather than a still portrait by tracing where your ancestors moved across the globe over time. The statistical method can also be used to model disease spread and studying how animals move through geographic regions. Read more ›

New research strongly suggests that Kawasaki disease is caused by a single respiratory virus that is yet to be identified. Findings contradict the theory that many different pathogens or toxins could cause this disease that can lead to serious cardiac complications in young children. Read more ›
