Researchers from Skoltech have found a way to help computer vision algorithms process satellite images of the Earth more accurately even with very limited data for training. This will make various remote sensing tasks easier for machines and ultimately the people who use their data. The paper outlining the new results was published in the journal Remote Sensing.
Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they've found one. In a pair of papers, researchers at the University of Maryland's (UMD) Quantum Materials Center (QMC) and colleagues have shown that uranium ditelluride (or UTe2 for short) displays many of the hallmarks of a topological superconductor--a material that may unlock new ways to build quantum computers and other futuristic devices.
WINSTON-SALEM, NC, July 15, 2021 - Answering a charge from the National Science Board, the RegenMed Development Organization (ReMDO), through its RegeneratOR Workforce Development Initiative, has released the results of a national survey of regenerative medicine biomanufacturing knowledge, skills, and abilities needed for successful employment in the regenerative medicine field.
A screening tool used to evaluate the need for endometrial cancer biopsies in women frequently misses the signs of this cancer in Black women, according to a new study released today in JAMA Oncology.
Dr. Kemi Doll, the lead researcher, and a gynecologic oncologist with the University of Washington School of Medicine, says that the results of the study suggest that the current non-invasive option of transvaginal ultrasound, or TVUS, to determine the appropriateness of a biopsy is not sufficiently accurate or racially equitable with regards to Black women.
Hiroshi Tanimoto, Director of the Earth System Division at the National Institute for Environmental Studies (NIES), Japan, and Astrid Müller together with their international research team, have developed a new method to evaluate satellite observations of XCO2 over open ocean areas, which are currently inaccessible through established validation network sites. In the new approach, a reference CO2 dataset is formulated by combining cargo ship and passenger aircraft observations which were conducted in cooperation with operators of the private sector.
(Background)
A team of researchers from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Liège and the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy have developed a microswimmer that appears to defy the laws of fluid dynamics: their model, consisting of two beads that are connected by a linear spring, is propelled by completely symmetrical oscillations. The Scallop theorem states that this cannot be achieved in fluid microsystems. The findings have now been published in the academic journal Physical Review Letters.
University of Utah paleontologists David Peterman and Kathleen Ritterbush know that it's one thing to use math and physics to understand how ancient marine creatures moved through the water. It's another thing to actually put replicas of those creatures into the water and see for themselves. They're among the scientists who are, through a range of methods including digital models and 3-D printed replicas, "de-fossilizing" animals of the past to learn how they lived.
If you didn't have a brain, could you still figure out where you were and navigate your surroundings? Thanks to new research on slime molds, the answer may be "yes." Scientists from the Wyss Institute at Harvard University and the Allen Discovery Center at Tufts University have discovered that a brainless slime mold called Physarum polycephalum uses its body to sense mechanical cues in its surrounding environment, and performs computations similar to what we call "thinking" to decide in which direction to grow based on that information.
"The solar energy-to-electricity conversion of perovskite solar cells is unbelievably high, around 25%, which is now approaching the performance of the best silicon solar cells," says Professor László Forró at EPFL's School of Basic Sciences. "But their central element is lead, which is a poison; if the solar panel fails, it can wash out into the soil, get into the food chain, and cause serious diseases."
Equatorial Asia, which includes Indonesia, Malaysia, Papua New Guinea, and surrounding areas, experienced devastating biomass burning in 2015 due to the severe drought condition induced by the extreme El Niño and a positive anomaly of the Indian Ocean dipole. This biomass burning emitted a significant amount of carbon, mainly in the form of carbon dioxide (CO2), into the atmosphere.
When a CEO steps down or is dismissed, the attention of the board is on how to choose the right executive to succeed that CEO. However, Bocconi University professor Dovev Lavie claims that managing the process of introducing the new CEO and choking the negative sentiment that can arise among stakeholders in a moment of uncertainty could be a more critical task, especially when the new CEO comes from outside the firm.
BOSTON - New research in humans and mice identifies a particular signaling molecule that can help modify inflammation and the immune system to protect against Alzheimer's disease. The work, which was led by investigators at Massachusetts General Hospital (MGH), is published in Nature.
New York, NY--July 14, 2021-- A previously unknown kind of human brain cell appears to help people center themselves in their personal maps of the world, according to a new study from neuroscientists at Columbia Engineering. This discovery sheds light on the cellular mechanisms underlying navigation and memory in humans, as well as what parts of the brain might get disrupted during the kinds of memory impairments common in neurodegenerative diseases such as Alzheimer's.
A football is not a quantum particle. There are crucial differences between the things we know from everyday life and tiny quantum objects. Quantum phenomena are usually very fragile. To study them, one normally uses only a small number of particles, well shielded from the environment, at the lowest possible temperatures.
