Webb Telescope offers first glimpse of an exoplanet’s interior

2024-05-20

A surprisingly low amount of methane and a super-sized core hide within the cotton candy–like planet WASP-107 b. The revelations, based on data obtained by the James Webb Space Telescope, mark the first measurements of an exoplanet’s core mass and will likely underpin future studies of planetary atmospheres and interiors, a key aspect in the search for habitable worlds beyond our solar system. “Looking into the interior of a planet hundreds of light-years away sounds almost impossible, but when you know the mass, radius, atmospheric composition, and hotness of its interior, you’ve got ...

Alkyl-aromatic hybrid micelles formed from emergent umbrella-shaped molecules

2024-05-20

Micelles assemble in water from amphiphilic molecules, composed of hydrophilic and hydrophobic frameworks. They can be found all around us, for example in soaps, detergents, and shampoos. Their main application is the water-solubilization of insoluble molecules through encapsulation into hydrophobic cavities. These cavities are conventionally composed of linear alkyl-chains, providing good interactions with alkyl-based guests, yet poor interactions with aromatic compounds. In addition, the rather weak intermolecular alkyl-alkyl type ...

First study from the African Ancestry Neuroscience Research Initiative identifies key genes in the brain that account for higher rates of some brain disorders in Black Americans

2024-05-20

BALTIMORE, Md. (May 20, 2024) – Scientists seeking to counter the neglect of African Americans in neuroscience research have found evidence that genetic ancestry is responsible for the increased prevalence of certain neurological disorders, such as Alzheimer’s disease and stroke, and decreased prevalence of others, including Parkinson’s disease, in Black Americans, according to new research published May 20 as the June cover story in the journal Nature Neuroscience. In contrast, the scientists from the Lieber Institute for Brain Development did not find evidence that genetic ancestry is responsible for differences in the ...

NIH awards Coast-to-Coast Consortium $5.6 million for All of Us Research Program

2024-05-20

Researchers at the University of California San Diego have been awarded a $5.6 million grant through the Coast-to-Coast Consortium (C2C) to further their pioneering efforts with the National Institutes of Health's (NIH) All of Us Research Program. The award is designated to facilitate participant engagement, enrollment, data collection, and retention. C2C will build on the foundation set by the UCSD-led California Precision Medicine Consortium (CAPMC), established in 2018, which enrolled more than 65,500 participants to the program. This award follows the program's ...

Ben-Gurion University scientist hunts for drug candidate to treat brain tumors

2024-05-20

BEER-SHEVA, Israel, May 20, 2024 – When you disable the brakes on a race car, it quickly crashes. Dr. Barak Rotblat wants to do something similar to brain cancer cells. He wants to disable their ability to survive glucose starvation. In fact, he wants to speed the tumor cells up, so they just as quickly die out. It is a novel approach to brain cancer based on a decade of research in his lab. He and his students' and co-lead researcher Gabriel Leprivier of the Institute of Neuropathology at University Hospital Düsseldorf ...

New Health Blueprint maps healthier future for rural, underserved Southwest Virginia

2024-05-20

A sweeping new Health Blueprint for Southwest Virginia highlights the grave health challenges that grip the rural region but also proposes solutions to help residents live longer, healthier lives. The Blueprint was assembled by the University of Virginia College at Wise’s Healthy Appalachia Institute, the Southwest Virginia Health Authority, UVA Health’s Center for Telehealth and a coalition of residents and regional healthcare providers. The document identifies priority health concerns for the three health districts in the southwestern corner of Virginia: Lenowisco, Cumberland Plateau and Mount Rogers. These are areas ...

Survival benefit associated with participation in clinical trials of anticancer drugs

2024-05-20

About The Study: Many studies suggest a survival benefit for cancer trial participants. However, these benefits were not detected in studies using designs addressing important sources of bias and confounding. Pooled results of high-quality studies are not consistent with a beneficial effect of trial participation on its own. Quote from corresponding author Jonathan Kimmelman, Ph.D.: “Many physicians, policymakers, patient advocates, and research sponsors believe patients have better outcomes when they participate in trials, even if they are in the comparator arm. Educational ...

Expanding on the fundamental principles of liquid movement

2024-05-20

Fukuoka, Japan—From the rain drops rolling down your window, to the fluid running across a COVID rapid test, we cannot go a day without observing the world of fluid dynamics. Naturally, how liquids traverse across, and through, surfaces are a heavily researched subject, where new discoveries can have profound effects in the fields of energy conversion technology, electronics cooling, biosensors, and micro-/nano-fabrications. Now, using mathematical modeling and experimentation, researchers from Kyushu University’s Faculty of Engineering have expanded on a fundamental principle in fluid dynamics. Their new findings may ...

Chemical Insights Research Institute partners with Duke University and the East-West Center to examine dust and ash from devastating Hawai’ian wildfires

2024-05-20

ATLANTA - Chemical Insights Research Institute (CIRI) of UL Research Institutes applies cutting edge technologies to evaluate the toxicity of burn-impacted land areas affected by the August 2023 Lahaina wildfires. Created with CIRI research partners from Duke University and the East-West Center (EWC) in Hawai’i, the study known as Lahaina Environmental Assessment Project (LEAP), will collect and analyze residual dust, soil and ash samples from properties affected by the fires. These residues, including fine dust, ...

NCCN publishes new resource for patients with intestinal cancer type most have never heard of before diagnosis

2024-05-20

PLYMOUTH MEETING, PA [May 20, 2024] — The National Comprehensive Cancer Network® (NCCN®) today announced publication of new NCCN Guidelines for Patients®: Small Bowel Adenocarcinoma. This free resource for people facing cancer and caregivers is focused on a rare cancer type that typically occurs in the small intestine, where routine screening is impossible, even for high-risk individuals. The small amount of patient information that exists for this cancer type tends to combine it with other cancers of the small intestine (such as sarcomas, neuroendocrine tumors, or lymphomas) despite very different treatment approaches and results. The NCCN Guidelines for Patients: ...
