Fossils of footprints over 160 million years old have helped palaeontologists at the University of Leicester to narrow down when pterosaurs adapted to live on the ground. These awe-inspiring flying reptiles of the Mesozoic era are often imagined soaring over the heads of dinosaurs. But new research shows that some of these ancient creatures were just as comfortable walking on the ground. In a groundbreaking new study published today in Current Biology (1 May), scientists at the University of Leicester have ...

Study data reveal how a specific sequence of cancer therapies can improve outcomes for patients with hard-to-treat lymphomas Relapsed/refractory (R/R) mature T and natural killer (NK)-cell lymphomas (TNKL) are aggressive blood cancers often resistant to frontline therapies. A team of Mass General Brigham researchers found that patients with these lymphomas had improved survival rates when treated with small molecule inhibitors as second-line therapy, followed by epigenetic modifiers as third-line therapy. Results of the study are published in the British Journal of Haematology. “Our robust ...

A team of researchers from the Keck School of Medicine of USC has developed an advanced tool for analyzing chimeric antigen receptor (CAR) T cells, including how they evolve during manufacturing and which ones are most effective at killing cancer. Using the platform, which leverages a laser-based technology known as spectral flow cytometry, researchers have already found one key insight: CAR T cells are better equipped to fight cancer after a shorter five-day expansion process than at the 10-day mark. The study was just published in the 25th anniversary special issue of Molecular Therapy, the flagship journal of the American Society of Gene & Cell Therapy. CAR ...

Fukuoka, Japan—The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death. Controlled death of cells, or programmed cell death, is also necessary for the proper development and function of the body. It has also been a focus of researchers developing treatments for cancer by finding ways to activate the cell death of cancer cells themselves. Ferroptosis is a recently discovered form of programmed cell death and has been a promising target for the ...

COLUMBUS, Ohio – A new study shows how damaging it can be for college students in introductory STEM classes to compare how hard they work to the extent of effort put in by their peers.   Researchers studied students in an introductory chemistry class, one of the STEM (Science, Technology, Engineering and Mathematics) fields. They found that those who thought they had to work harder than others in class were less likely to believe they had the ability to succeed in science.   This focus on comparative effort was bad for both men and women in the class. But women showed positive effects of thinking they tried hard in the class ...

For years, estrogens were known as the reproductive hormones produced by the ovaries, but recent discoveries reveal that these hormones are also synthesized in the brain through an enzyme called aromatase. This brain-specific version of estrogen is called neuroestrogen, and while its presence has been known, its precise function remained unclear—until now. Researchers from Fujita Health University reveal a groundbreaking discovery suggesting the direct role of neuroestrogen in appetite regulation. “It is well known that MC4R (melanocortin-4 receptor) is an important receptor in the brain that regulates food intake,” explains lead author Takanori Hayashi, Associate Professor ...

Could it be possible to diagnose Parkinson's disease with the help of a simple retinal exam? The idea should be seriously considered, according to a study published in the May issue of Neurobiology of Disease by researchers from Université Laval who discovered that the retina of people with Parkinson's disease responds differently to light stimuli than that of healthy people. Parkinson's disease is usually diagnosed when a person consults a doctor because of motor problems such as tremors. “By then, the disease has been present for several ...

Scientists have for the first time provided insight into how bomb residue transfers to the hands of suspects, which could lead to stronger evidence in court. The study, which was led by a team from King’s College London and published today in the journal Science & Justice, investigated how explosive materials commonly found in pipe bombs and improvised explosive devices (IEDs) transferred to the palms and fingers of individuals who handled them. The researchers learned that the amount that was handled and the unique characteristics of the handler were important determining factors. Surprisingly, ...

Parenting in the hospital is stressful. Moms and dads naturally focus on their ill child, sometimes to the neglect of their own mental health.
