Swapping out red meat for certain plant-based meat alternatives can improve some cardiovascular risk factors, according to a new study by researchers at Stanford Medicine.
The small study was funded by an unrestricted gift from Beyond Meat, which makes plant-based meat alternatives, and used products from the company in comparing the health effects of meat with plant-based alternatives. Beyond Meat was not involved in designing or conducting the study and did not participate in data analysis.
"Memory is the first thing to go."
Everyone has heard it, and decades of research studies seem to confirm it: While it may not always be the first sign of aging, some faculties, including memory, do get worse as people age.
It may not be that straightforward.
A research team led by Daniel Lietha has just published in The EMBO Journal the mechanistic details of the activation of the Focal Adhesion Kinase (FAK) on lipid membranes. Lietha started this research during his work at the Spanish National Cancer Research Centre (CNIO) and has culminated it in his current institution, the Centro de Investigaciones Biológicas Margarita Salas (CIB-CSIC).

Organocatalysts consisting of organic compounds without metal elements are receiving much attention as next generation catalysts in the hope of reducing environmental burden and coping with exhaustion/rising prices of rare metals. However, it is difficult for an organocatalyst to control radical reactions involving a single electron with high reactivity. Thus, reaction processes mediated by organocatalysts are rather limited. This hinders the development and application of organic synthesis by the use of organocatalysts.
Results from a recent clinical trial indicate that for older adults with advanced cancer, initiating aspirin may increase their risk of disease progression and early death.
The study, which was conducted by a binational team led by researchers at Massachusetts General Hospital (MGH), the Berman Center in Minnesota, and Monash University in Australia, is published in the Journal of the National Cancer Institute.
Classical phase transitions are governed by temperature. One of the most familiar examples is the phase transitions of water from solid to liquid to gas. However, other parameters govern phase transitions when temperatures approach absolute zero, including pressure, the magnetic field, and doping, which introduce disorder into the molecular structure of a material.
Thousands of chemical processes used by the energy industry and for other applications rely on the high speed of catalytic reactions, but molecules frequently are hindered by molecular traffic jams that slow them down. Now an entirely new class of porous catalysts has been invented, using unique fins to speed up the chemistry by allowing molecules to skip the lines that limit the reaction.
This discovery was published in Nature Materials, the leading journal of materials science.
A new UC Davis Health study found that common gastrointestinal (GI) symptoms such as diarrhea, constipation and bloating are linked to troubling sleep problems, self-harm and physical complaints in preschool children. According to the study, published Aug.
Scientists from the University of Sheffield have used mathematical modelling to understand why flocks of long-tailed tits segregate themselves into different parts of the landscape.
The team tracked the birds around Sheffield's Rivelin Valley which eventually produced a pattern across the landscape, using maths helped the team to reveal the behaviours causing these patterns.
Denver--(Embargoed for 7 a.m. EST August 8, 2020)--Patients with non-small cell lung cancer (NSCLC) carrying anaplastic lymphoma kinase (ALK) gene alterations who received ensartinib experienced substantially longer progression-free survival than a matched group of patients who received crizotinib, according to a presentation at the International Association for the Study of Lung Cancer World Conference on Lung Cancer Virtual Presidential Symposium.
In research published in Science Advances, a group led by scientists from the RIKEN Center for Emergent Matter Science (CEMS) have used a principle, "magneto-rotation coupling," to suppress the transmission of sound waves on the surface of a film in one direction while allowing them to travel in the other. This could lead to the development of "acoustic rectifiers"--devices that allow waves to propagate preferentially in one direction, with potential applications in communications technology.
The ongoing COVID-19 pandemic is shining a bright spotlight on vaccine development. As numerous vaccines race through clinical trials, physicians and researchers continue to work on developing new vaccine technologies to generate the most effective vaccines with the fewest side effects.
A new proof-of-concept study by researchers at the University of Chicago and Duke University demonstrates the potential for one such platform, using self-assembling peptide nanofibers tagged with antigens to prime the immune system against a potential invasion.
Helium is the second most abundant element in the universe after hydrogen. But scientists aren't sure just how much there actually is in the Sun's atmosphere, where it is hard to measure. Knowing the amount of helium in the solar atmosphere is important to understanding the origin and acceleration of the solar wind - the constant stream of charged particles from the Sun.
A detailed study of roaming reactions - where atoms of compounds split off and orbit other atoms to form unexpected new compounds - could enable scientists to make much more accurate predictions about molecules in the atmosphere, including models of climate change, urban pollution and ozone depletion.
In a paper published today in the journal Science, a team of researchers from UNSW Sydney, University of Sydney, Emory University and Cornell University showed in unprecedented detail exactly what happens during roaming reactions of chemical compounds.
A study led by researchers at Florida Atlantic University's Harbor Branch Oceanographic Institute examined toxins in tissue concentrations and pathology data from 83 stranded dolphins and whales along the southeastern coast of the United States from 2012 to 2018. Researchers examined 11 different animal species to test for 17 different substances in animals found on the shores in North Carolina and Florida.
