Hydrogen is the most abundant element in the universe and it plays important roles in the structure, dynamics, and evolution of the planets. Hydrogen is transported into deep mantle regions as a hydrous mineral via the subduction of oceanic plates. To better understand the global hydrogen circulation in the Earth's mantle, a number of high-pressure experiments were conducted on the stability of hydrous phases under lower mantle conditions.
For the first time, researchers have been able to record, frame-by-frame, how an electron interacts with certain atomic vibrations in a solid. The technique captures a process that commonly causes electrical resistance in materials while, in others, can cause the exact opposite--the absence of resistance, or superconductivity.
SASKATOON - Chemicals commonly used in smartphone, television, and computer displays were found to be potentially toxic and present in nearly half of dozens of samples of household dust collected by a team of toxicologists led by the University of Saskatchewan (USask).
The international research team, led by USask environmental toxicologist John Giesy, is sounding the alarm about liquid crystal monomers--the chemical building blocks of everything from flat screen TVs to solar panels--and the potential threat they pose to humans and the environment.
CHAPEL HILL, NC - December 11, 2019 - The UNC School of Medicine has awarded the 20th Perl-UNC Neuroscience Prize to Lily Jan, PhD, and Yuh-Nung Jan, PhD, both at UC San Francisco, for the "discovery and functional characterization of potassium channels."
The husband-and-wife team will visit Chapel Hill March 26, 2020 to receive the prize - a $20,000 award - and give a lecture on their work at 3 p.m. in room G202 of the Medical Biomolecular Research Building (MBRB).
CHICAGO--December 10, 2019-- Patients who do not disclose use of other medications are at higher risk of adverse drug interactions and addiction, according to new research in The Journal of the American Osteopathic Association.
A new article outlines common drug-drug interactions that alter how the body metabolizes certain opioids, causing decreased efficacy that ultimately can lead to misuse and overdose. The authors estimate that around 30 percent of patients experience such interactions; however, very few are detected and reported.
Can two layers of the "king of the wonder materials," i.e. graphene, be linked and converted to the thinnest diamond-like material, the "king of the crystals"? Researchers of the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS, South Korea) have reported in Nature Nanotechnology the first experimental observation of a chemically induced conversion of large-area bilayer graphene to the thinnest possible diamond-like material, under moderate pressure and temperature conditions.
Proteins are the building blocks of life and play a key role in all biological processes. Understanding how they interact with their environment is therefore vital to developing effective therapeutics and the foundation for designing artificial cells.
Some of the most important, and difficult, conversations in healthcare are the ones that happen amid serious and life-threatening illnesses. Discussions of the treatment options and prognoses in these settings are a delicate balance for doctors and nurses who are dealing with people at their most vulnerable point and may not fully understand what the future holds.
RIVERSIDE, Calif. -- A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium.
The calculations take scientists a step closer to realizing a gamma-ray laser, which may have applications in medical imaging, spacecraft propulsion, and cancer treatment.
SAN DIEGO, December 6, 2019 -- Schools of fish can scatter sound waves, which has impacts on fish farming. Fisheries acoustics have been studied for over 40 years to assess biomass and optimize aquaculture applications.
The talk "Mesoscopic wave physics in a dense fish school" will be presented Dec. 6 at the 178th Meeting of the Acoustical Society of America as part of a session on general topics in physical acoustics. The convention will be held at the Hotel del Coronado in San Diego.
RIVERSIDE, Calif. -- Physicists at University of California, Riverside, have designed an experiment to explain the concept of magnetic resonance. The project was carried out by undergraduate students in collaboration with local high school teachers.
SAN FRANCISCO (December 5, 2019) - In 2019, researchers at the California Academy of Sciences added 71 new plant and animal species to our family tree, enriching our understanding of Earth's complex web of life and strengthening our ability to make informed conservation decisions.
Physicians who treat patients with triple negative breast cancer have two new ways to predict which patients may benefit most from the well-established post-surgery treatment known as AC chemotherapy, short for adjuvant doxorubicin and cyclophosphamide.
A recent study by a team of scientists in Korea reveals new findings about how various systems involved in cellular surveillance interact. This research is the first to identify a "cross-talk" molecule between these systems. Because these pathways are involved in fighting toxic cellular or foreign substances, the study has various potential applications in antiviral development, gene therapy, and agriculture.
In 2017, the Heising-Simons Foundation -- a family foundation that works in climate and clean energy, science, education, and human rights -- established the 51 Pegasi b Fellowship to support early-career astronomers engaged in planetary research. Just over a year later, the Foundation announced that it would overhaul the selection process for the program because, out of 12 fellowships awarded in the program's first two years, only two -- one each year -- went to female scientists.
