While everybody agrees that our blue planet is rich in water, this observation is at odd, first, with the exploration of other rocky planets, genuinely lacking surface water, and second, with the idea of a giant impact between the proto-Earth and a planetary embryo the size of Mars that created the Moon. Such a catastrophic event should have vaporized any pre-existing water, leaving behind a dry Earth.
One of the major objectives in biology is to understand the factors and mechanisms that have led to the diversification of species on earth. Plant-feeding insects are the most diversified group of organisms on earth, and they account for more than 40% of all insects. There have been numerous studies into the diversification patterns and driving forces looking at host plants, however, interactions with other organisms had yet to be accounted for.
"Hair surface engineering: modification of fibrous materials of biological origin using functional ceramic nano containers", a project headed by Rawil Fakhrullin, is supported by the Russian Science Foundation.
WASHINGTON, D.C., April 10 - Agricultural Research Service (ARS) scientists and their colleagues have discovered a gene that can be used to develop varieties of wheat that will be more resistant to Fusarium Head Blight (FHB), a disease that is a major threat both overseas and to the nation's $10 billion annual wheat crop.
PHILADELPHIA--A prospective "PARP inhibitor" drug that has struggled to show effectiveness in clinical trials against cancers can be structurally modified to greatly increase its power to kill tumor cells, researchers from Penn Medicine report this week in Science.
The team also showed that PARP inhibitor compounds can be "tuned" in the opposite way so that they inhibit PARP-1 enzymes without killing cells, thus potentially making this class of drugs more useful for treating heart disease and other non-cancer conditions where inhibiting PARP-1 is the goal.
Imagine the advances to predictive modeling if you could infer something about how light amplifies colors in a bird's plumage from the way seismic waves propagate through mountain systems.
That's a bit of hyperbole that nevertheless suggests the "beautiful" utility of new mathematical formulas devised by Princeton Professor of Chemistry Salvatore Torquato and sixth-year graduate student Jaeuk Kim of the Department of Physics as they advance our understanding of how different types of waves behave inside materials.
CHICAGO (April 9, 2020): Within a month of the University of California San Francisco (UCSF) Health treating its first patient with coronavirus disease 2019 (COVID-19) on Feb. 3, UCSF surgeons began formulating a plan to respond to the pandemic and help manage the health care system's available resources.
TROY, N.Y. -- An instrument currently aboard the International Space Station could grow E. coli bacteria in space, opening a new path to bio-manufacturing drugs during long term space flights. Research published today in Nature Microgravity used an Earth-bound simulator of the space station instrument to grow E. coli, demonstrating that it can be nurtured with methods that promise to be more suitable for space travel than existing alternatives.
Screening DNA of Parkinson's patients in the Christine Van Broeckhoven laboratory (VIB-UAntwerpen Center for Molecular Neurology) identified a new risk gene for Parkinson's disease. Mutations in ATP10B resulted in loss of ATP10B protein. The function of the ATP10B gene was revealed by the Peter Vangheluwe lab (KU Leuven, Laboratory of Cellular Transport Systems). They identified ATP10B as a transporter for glucosylceramide, a lipid that plays a central role in Parkinson's disease. Disease mutations disturb this function.
Action real-time strategy video games such as World of Warcraft, Age of Empires, and Total War are played by millions. These games, which can be won through strategic planning, selective attention, sensorimotor skills, and teamwork place considerable demands on the brain.
Dr. Hyoungchul Kim's research team, from the Center for Energy Materials Research at the Korea Institute of Science and Technology (KIST, Acting President Yoon, Seok-jin), have successfully developed a sulfide-based *superionic conductor that can be used to a high-performance solid electrolyte in all-solid-state batteries. This new material delivers the Li-ion conductivity of 10.2 mS/cm at room temperature and is comparable to that of liquid electrolytes used for typical Li-ion batteries.
Analyses of four fossilized molars newly excavated along the left bank of the Yuruá River in the Peruvian Amazon suggest another primate lineage distinct from the Platyrrhini - until now considered to be the only primate group ever to inhabit the New World - also occupied the New World for a brief period of time. The teeth strongly resemble those of Parapithecidae, a now-extinct family of higher-order primates that resided in Northern Africa around the Eocene (56 to 33.9 million years ago) and Oligocene period (33.9 million to 23 million years ago).
Strong winds blow high in the atmosphere of the brown dwarf 2MASS J1047+21, according to a new study, which presents a simple method to deduce the windspeed in other brown dwarf atmospheres, too. By monitoring the brown dwarf's infrared and radio emissions, the researchers were able to derive the distant world's powerful winds - which whip eastward at an average of 660 meters per second, or roughly 2,400 kilometers per hour. The results demonstrate a technique that could be used to characterize atmospheres of exoplanets.
