As he discussed how the pallid sturgeon has responded to differing conditions along the Missouri River, the mind of soft-spoken fish ecologist Mark Pegg drifted to a Def Leppard lyric inspired by Neil Young.
"What is the old song? 'It's better to burn out than to fade away?' In this case, I'm not sure that's true," said Pegg, a professor with the University of Nebraska-Lincoln's School of Natural Resources.
Lithium-ion batteries (LIBs) are a common type of rechargeable batteries. Their versatile nature and numerous applications in all sorts of electronic devices--from mobile phones to cars--makes them seem too good to be true. And perhaps they are: recently, there has been an increase in the number of fire-related incidents associated with LIBs, especially during charging, causing serious concerns over their safety. Scientists now know that these incidents can be due to the use of a broken or unauthorized charger.
Integrating first-of-its-kind washable hydrogel electrodes with a pulse sensor, researchers from the University of Massachusetts Amherst have developed smart eyewear to track eye movement and cardiac data for physiological and psychological studies. The eyewear--known as Chesma and presented August 20 in the journal Matter--provides accurate measurements in an everyday environment without compromising users' comfort.
A trend of higher lung cancer incidence rates in young Black people versus young white people in the United States has flipped, with the Black/white gap disappearing in men and reversing in women. The changing trends coincide with steeper declines in smoking in Black Americans, according to a new study, which appears in JNCI Cancer Spectrum.
LOS ANGELES (Aug. 20, 2020) - Robotic surgery for patients with early stage, oropharyngeal squamous cell cancer is associated with improved health outcomes, including better long-term survival, according to a Cedars-Sinai study published Thursday in JAMA Oncology. Oropharyngeal cancer occurs in the back of the throat and includes the base of the tongue and tonsils.
A team of researchers from the University of Hawai'i (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST) identified a global tendency for future sea levels to become more variable as oceans warm this century due to increasing greenhouse gas emissions. Sea level variability alters tidal cycles and enhances the risks of coastal flooding and erosion beyond changes associated with sea level rise.
AMHERST, Mass. - From the team that invented physiology-sensing pajamas at the University of Massachusetts Amherst, now comes a new, lightweight eye mask that can unobtrusively capture pulse, eye movement and sleep signals, for example, when worn in an everyday environment.
LOUISVILLE, Ky. - Fatty acid binding proteins (FABPs) serve as a type of chaperone, coordinating the transport of fatty acids and other molecules between cells. Bing Li, Ph.D., associate professor in the Department of Microbiology and Immunology at the University of Louisville and a leading researcher in understanding the role of FABPs, has created a "SnapShot" of the functions of these proteins published in the journal Cell, a highly regarded scientific journal covering cell biology.
Lipids are very essential components in composing living systems and are important for cell signaling and nutrient transport. Meanwhile, lipids have been widely used as carriers in many anticancer drugs development because of their capability in increasing solubilization and improving pharmacokinetics of drugs. Based on this, lipid-oligonucleotides (LONs), the new molecular materials have been designed and have shown outstanding properties in different molecular designs for applications from bioanalysis and biosensing to biomedical technologies.
Noise sensitivity, fear of novel situations and, for example, fear of slippery surfaces and heights are common behavioural problems among dogs. According to a behavioural survey of nearly 14,000 dogs conducted at the University of Helsinki, these non-social fears are associated with factors related to the dogs' living environment, lifestyle and breed.
Dogs that were engaged in activities the most and were actively trained were found to be the least fearful.
The Sun is a magnetized star. Its magnetic field is essentially three dimensional and it occupies all layers of the solar atmosphere. However, routine measurements of the solar magnetic field have only been achieved at the photospheric level, or the solar surface.
Lacking precise knowledge about the magnetic field in the outermost solar atmosphere, the corona, has impeded our understanding of the solar magnetism and many phenomena in the solar atmosphere.
The results of a study conducted by scientists at the University of Turku, Åbo Akademi University, and University of Bristol, show that people who tend to react negatively to rules and recommendations have lower trust in medical doctors and a more negative attitude towards vaccines, or reject vaccines for themselves or their children.
Hydrogels are a class of soft materials resembling native soft tissues, which consist of cross-linked 3D networks formed by covalent bonds or physical interactions. Due to the high water content and viscoelastic nature, hydrogels are well suitable to encapsulate cells and bioactive factors, and therefore extensively investigated for applications in drug delivery and tissue engineering.
Researchers identify master regulator genes of asthma, provide new path forward in the study of asthma and the development of novel therapies.
Bottom Line: Identification of these master regulator genes provides a new path forward in the study of asthma and the development of novel therapies and treatments.
New Haven, Conn. -- A new technique developed by a Yale-led research team improves blood flow in surgically made blood vessels used in dialysis, enables them to last longer, and results in fewer complications than the standard technique.
The findings, based on work with hundreds of patients and supported by animal studies, appear in the August 19 edition of Science Translational Medicine.
