A link between evolution over short time frames (microevolution) and long time frames (macroevolution) that could open new approaches to understanding some of biology's deepest questions is proposed by Dr Owen Gilbert of the Department of Integrative Biology at the University of Texas at Austin (USA) in a new paper, published in the open-access, peer-reviewed journal
VANCOUVER, Wash. - The recovery of beavers may have beneficial consequences for amphibians because beaver dams can create the unique habitats that amphibians need.
That finding was reported by four WSU Vancouver scientists in a paper published in the journal Freshwater Biology. The research took place in the Gifford Pinchot National Forest of the Cascade Range, where the researchers identified 49 study sites either with or without beaver dams. The researchers found the beaver-dammed sites were 2.7 times higher in amphibian species richness than the undammed sites.
PHILADELPHIA-- A subcutaneous injection of the immune-boosting drug teclistamab was found to be safe and elicit responses in a majority of patients with relapsed or refractory multiple myeloma, according to findings from a multi-institutional phase I study being presented by Alfred L. Garfall, MD, an assistant professor of Medicine in the division of Hematology-Oncology in the Perelman School of Medicine at the University of Pennsylvania, at the annual American Society of Hematology & Exposition Meeting on Dec. 5 (abstract #180).
Spin-filtering could be the key to faster, more energy-efficient switching in future spintronic technology, allowing the detection of spin by electrical rather than magnetic means.
A UNSW paper published last month demonstrates spin detection using a spin filter to separate spin orientation according to their energies.
Ultra-fast, ultra-low energy 'spintronic' devices are an exciting, beyond-CMOS technology.
DETECTING SPIN VIA ELECTRICAL MEANS IN FUTURE SPINTRONICS
The future of mobility is electric cars, trucks and airplanes. But there is no way a single battery design can power that future. Even your cell phone and laptop batteries have different requirements and different designs. The batteries we will need over the next few decades will have to be tailored to their specific uses.
Philadelphia, December 4, 2020 - Researchers from a consortium of hospitals including Children's Hospital of Philadelphia (CHOP) have identified factors that make children with diabetic ketoacidosis more likely to experience acute kidney injury. Analyzing data from a large, multicenter clinical trial, the researchers also found that children who experience acute kidney injury are more likely to also experience subtle cognitive impairment and demonstrate lower IQ scores, suggesting a pattern of multiple organ injury. The findings were published online today in JAMA Network Open.
A new system for measuring solar performance over the long term in scalable photovoltaic systems, developed by Arizona State University researchers, represents a breakthrough in the cost and longevity of interconnected power delivery.
A new study by the UC Davis MIND Institute finds a connection between gestational age and attention deficit/hyperactivity disorder (ADHD) symptoms in children with Down syndrome. The research, published in Scientific Reports, focused on children born at 35 weeks gestation or older. It found that earlier gestational age was linked to increased ADHD symptoms later in childhood. Gestational age is the length of time a fetus has developed since the beginning, or gestation, of a pregnancy.
Heart disease is the main cause of death in developed countries. There is evidence that shows that factors related to lifestyle, such as diet, have an influence on developing these kinds of diseases. But, do they have any effect on patients who are already ill?
The group of so-called metal halide perovskites as materials has revolutionized the field of photovoltaics in recent years. Generally speaking, metal halide perovskites are crystalline materials that follow the structure ABX3, with varying composition. Here, A, B, and X can represent a combination of different organic and inorganic ions. These materials have a number of properties that are ideal for use in solar cells and could help to make optoelectronic devices such as lasers, light-emitting diodes (LEDs), or photodetectors much more efficient.
Scientists have recently revealed, both theoretically and experimentally, that germanium atoms can arrange themselves into a 2D "bitriangular" lattice on zirconium diboride thin films grown on germanium single crystals to form a "flat band material" with an embedded "kagome" lattice. The result provides experimental support to a theoretical prediction of flat bands emerging from trivial atomic geometry and indicates the possibility of their existence in many more materials.
Indolizines are a group of substances with biological and optical properties. A team of chemists from RUDN University developed a new approach to the synthesis of indolizines using pyridinium salts and enamiones. The new substances turned out to be able to emit light in the green range which can be useful for medical applications. The results of the study were published in the Molecules journal.
OAK BROOK, Ill. (December 4, 2020) - Breast cancer screening with digital breast tomosynthesis (DBT) offers significant advantages over digital mammography, including improved cancer detection and lower false negative rates, according to a study published in Radiology.
Astronomers have caught a rare look at a rapidly fading shroud of gas around an aging star. Archival data from NASA's Hubble Space Telescope reveal that the nebula Hen 3-1357, nicknamed the Stingray nebula, has faded precipitously over just the past two decades. Witnessing such a swift rate of change in a planetary nebula is exceeding rare, say researchers.
A new machine learning approach offers important insights into catalysis, a fundamental process that makes it possible to reduce the emission of toxic exhaust gases or produce essential materials like fabric.
