Using machine learning to better understand how water behaves

Water has puzzled scientists for decades. For the last 30 years or so, they have theorized that when cooled down to a very low temperature like -100C, water might be able to separate into two liquid phases of different densities. Like oil and water, these phases don’t mix and may…

Study examines bacteria living in and on mosquitoes

Avoiding mosquitoes to protect against bites is always a good idea. But a new North Carolina State University study shows that the bacteria-ridden exteriors of mosquitoes may be another reason to arm yourself with a swatter. The first-of-its-kind study, published in PLOS ONE, examined both the exterior surface and interior…

High School program linked to lower substance use, better health behaviors

New UCLA-led research finds that a college preparatory program for youth experiencing educational inequities that operates in about 13% of U.S public high schools has a positive effect on students’ social networks, psycho-social outcomes, and health behaviors. The findings, published Dec. 16 in the peer-reviewed journal Pediatrics, suggests that the…

Wearable skin patch monitors hemoglobin in deep tissues: A photoacoustic sensor could help clinicians diagnose tumors, organ malfunction and more

A team of engineers at the University of California San Diego has developed an electronic patch that can monitor biomolecules in deep tissues, including hemoglobin. This gives medical professionals unprecedented access to crucial information that could help spot life-threatening conditions such as malignant tumors, organ dysfunction, cerebral or gut hemorrhages…

Immune surprise: Recently evolved alarm molecule drives inflammation

Scientists from Trinity College Dublin have made an important breakthrough in understanding how inflammation is regulated. They have just discovered that a key immune alarm protein previously believed to calm down the immune response actually does the opposite. Their work has numerous potential impacts, especially in the context of understanding…

Scientists discover what was on the menu of the first dinosaurs

The earliest dinosaurs included carnivorous, omnivorous and herbivorous species, according to a team of University of Bristol palaeobiologists. By looking at the tooth shapes of the earliest dinosaurs and simulating their tooth function with computational modelling, experts were able to compare them to living reptiles and their diets. Their findings,…

Researchers have identified the origins of serious illness in children

The origins of the serious cancer-like disease LCH have been identified by researchers from Karolinska Institutet in collaboration with Karolinska University Hospital. The findings presented in Science Immunology may lead to new, targeted treatments. Langerhans’ Cell Histiocytosis (LCH) is a serious type of cancer-like disease that mainly affects children and…

Ancient grammatical puzzle solved after 2,500 years

A grammatical problem which has defeated Sanskrit scholars since the 5th Century BC has finally been solved by an Indian PhD student at the University of Cambridge. Rishi Rajpopat made the breakthrough by decoding a rule taught by “the father of linguistics” Pāṇini. The discovery makes it possible to ‘derive’…

A deep red, cranberry-tinted lipstick that’s also antimicrobial

Lipstick can be a confidence booster, enhance a costume and keep lips from chapping. But sharing a tube with a friend or family member can also spread infections. To develop a version with antimicrobial properties, researchers reporting in ACS Applied Materials & Interfaces have added cranberry extract to the formulation.…

New DNA analysis provides accurate tuberculosis genome

Researchers have developed a novel genome assembly tool that could spur the development of new treatments for tuberculosis and other bacterial infections. The new tool, which has created an improved genome map of one tuberculosis strain, should do likewise for other strains and other types of bacteria, according to researchers…

Drug combination for stage IV melanoma shows success in trial

A new multidrug treatment for patients with stage IV melanoma has proven effective after a three-year clinical trial at the University of Colorado Cancer Center. The study, which was designed and led by CU Cancer Center members, was aimed at overcoming the immune suppression that occurs in some patients with…
