Settling a decades-long debate about whether small Tyrannosaurus rex specimens represent a separate genus or rather just "kids" of their kind, a new examination of thinly sliced bones from two specimens at the Burpee Museum of Natural History in Illinois suggests the latter. The specimens were juveniles that had not yet experienced a major growth spurt before they died, the authors say.
The simultaneous use of antibodies based on two differing mechanisms of action leads to a more effective destruction of tumors. This has been demonstrated by a study in animal models by medical oncologists and scientists at the University of Basel that has been published in the scientific journal PNAS. Patients who do not respond to current immunotherapy options could benefit most from this new treatment.
A team of scientists from the Research Center "Fundamental Problems of Thermophysics and Mechanics" of the Samara Polytech is engaged in the construction of new mathematical models and the search for methods for their study in relation to a wide range of locally nonequilibrium transport processes in various physical systems. An innovative approach developed not so long ago is based on a modern version of third-generation thermodynamics.
COLUMBUS, Ohio - New research reported in the New England Journal of Medicine by the Centers for Disease Control and Prevention (CDC) in collaboration with The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) strengthens prior findings on the link between vitamin E acetate and EVALI (E-cigarette or vaping product use-associated lung injury).
NASA's Terra satellite passed over the Southern Pacific Ocean on Dec. 30 and found that Tropical Storm Sarai continued to move further away from Fiji and toward Tonga.
On Dec. 30, 2019, the Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite provided a visible image of Sarai that showed the storm had flaring convection and strongest thunderstorms around the low-level center. The storm also appeared elongated indicating it was weakening.
New Rochelle, NY, December 30, 2019--The delivery of ultrashort pulses of electrical energy represents a promising nonthermal, nonscarring method of inducing regulated cell death in common skin lesions. This and other novel approaches to applying electrical impulses to treat disease are published in Practical Applications of Bioelectric Stimulation, a special issue of Bioelectricity, a peer-reviewed journal from Mary Ann Liebert, Inc.
Two-dimensional solar materials may offer a way to extract more energy from sunlight. By tuning the structure of a 2D perovskite solar material, researchers from KAUST and the Georgia Institute of Technology have shown they can prolong the lifetime of highly energetic hot carriers generated by light striking the material. The approach could offer a way to capture solar energy more efficiently.
NASA analyzed the cloud top temperatures in Tropical Storm Sarai using infrared light to determine the strength of the storm. Sarai has triggered warnings for Fiji and Tonga in the Southern Pacific Ocean,
On Dec. 27, there are regional warnings in effect for Fiji and Tonga. In Fiji, there is a storm warning is in force for Vatulele and Kadavu. A gale warning is in force for Vanua Levu, Taveuni, Yasawa and the Mamanuca Group, Kadavu, Lomaiviti Group, Viti Levu and nearby smaller islands. Tonga is on tropical cyclone alert
PITTSBURGH, December 27, 2019 - Teenage boys who witness their peers abusing women and girls are much more likely to bully and fight with others, as well as behave abusively toward their dates, compared to teenage boys who don't witness such behaviors, according to an analysis led by the University of Pittsburgh School of Medicine and UPMC Children's Hospital of Pittsburgh.
During the past years, artificial intelligence (AI) -- the capability of a machine to mimic human behavior -- has become a key player in high-techs like drug development projects. AI tools help scientists to uncover the secret behind the big biological data using optimized computational algorithms. AI methods such as deep neural network improves decision making in biological and chemical applications i.e., prediction of disease-associated proteins, discovery of novel biomarkers and de novo design of small molecule drug leads.
A group of researchers from the Skoltech Center for Computational and Data-Intensive Science and Engineering (CDISE) took 4th place in the international MRI-based adolescent intelligence prediction competition. For the first time ever, the Skoltech scientists used ensemble methods based on deep learning 3D networks to deal with this challenging prediction task. The results of their study were published in the journal Adolescent Brain Cognitive Development Neurocognitive Prediction.
NASA-NOAA's Suomi NPP satellite provided a visible image of Phanfone as it continues moving through the South China Sea. Visible imagery showed that the storm is less organized and elongated as the storm weakened from a typhoon to a tropical storm.
Macular degeneration (AMD) causes blindness in millions of people in the Western world. It is the most common cause of severe vision loss in the Western world among those aged 50 and over, and its prevalence increases with age. Though there is no cure for AMD, significant recent advancements in artificial retina implants may lead to effective treatment.
Scientists from Far Eastern Federal University (FEFU) teamed up with colleagues from Institute of Chemistry (FEB RAS), Institute for Single Crystals (Ukraine), and Shanghai Institute of Ceramics (Chinese Academy of Sciences) to develop Y2O3?MgO nanocomposite ceramics with uniform distribution of two phases, microhardness over 11 GPa, and average grain size of 250 nm. It capable of transmitting over 70% of IR-range with wavelength up to 6,000 nm. A related article was published in Ceramics International.
Researchers in the Cellular and Molecular Synaptic Function Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) have elucidated the roles of cytoskeletal proteins at the giant presynaptic terminal, called the calyx of Held, visualized in rat brainstem slices. Initial findings were made by a graduate school student Lashmi Pyriya for her PhD thesis work under technical instructions by Dr Kohgaku Eguchi (now in IST Austria) and Dr Laurent Guillaud.
