WASHINGTON, September 15, 2020 -- Four-hundred fifty light-years from Earth, a young star is glowing at the center of a system of concentric rings made from gas and dust, and it is producing planets, one for each gap in the ring.
Its discovery has shaken solar system origin theories to their core. Mayer Humi, a scientist from the Worcester Polytechnic Institute, believes it provides an apt study target for theories about protoplanetary rings around stars. The research is published in the Journal of Mathematical Physics, by AIP Publishing.
Durham, NC - Human pluripotent stem cells (hPSCs) hold promise in the field of regenerative medicine for how they give rise to every other cell type in the body and for their ability to propagate indefinitely. Their potential, however, is hampered by the body's tendency to reject any "allogeneic" cells or tissue, which means that the cells come from a donor other than the patient.
San Diego, CA - The COVID-19 pandemic has created a number of challenges, including that many are spending more time at home than ever before. This is a significant problem for those with neighbors who smoke. Smoking continues to be a problem in multi-unit housing, and while stay-at-home orders have helped to reduce transmission of COVID-19, they have also increased exposure to secondhand smoke from neighbors.
The growing demands for ultrahigh energy density batteries used in electronic devices, electrical vehicles, and large-scale energy storage have inspired wide search on novel electrode materials, especially high-capacity cathode materials for Li-ion batteries (LIBs). The traditional design paradigm for the transition-metal oxide (TMO) based cathodes, e.g., LiCoO2, LiMn2O4, LiFePO4 are to use TM as the sole source of electrochemical activity, and their theoretical capacity is limited by the number of electrons that TM can exchange per unit mass.
The photon jet effect was discovered in the early 2000s. The jet is an electromagnetic wave focused at the surface of a quartz glass microsphere, which is at lens focus. This jet has a unique transverse dimension, which is less than the diffraction limit. This feature of the photon jet drew the attention of scientists. As a result, in 2011, a nanoscope based on the effect of a photonic jet was developed. It pushed the envelope of traditional optical microscopes limitation with a maximum resolution of 200 nanometers and made possible to observe up to 50 nanometers.
The Wnt signalling pathway has been studied for decades, still it holds surprises in store. Bon-Kyoung Koo, group leader at IMBA - Institute of Molecular Biotechnology of the Austrian Academy of Sciences and Tadasuke Tsukiyama at the Hokkaido University have now uncovered a new and unexpected role for a key component of the Wnt pathway, Casein Kinase-1, in regulating the pathway at the plasma membrane.
Rupert Seidl (Professor of Ecosystem Dynamics and Forest Management in Mountain Landscapes at TUM) and his colleague Cornelius Senf (lead author of the study) for the first time produced a high-resolution map of all openings in the canopy of European forests. They have analyzed more than 30,000 satellite images and identified more than 36 million areas where large trees have given way to open spaces of young trees. This corresponds to a loss of the canopy in 17 percent of the European forests in 30 years.
A new study has shown HGV drivers drive much more safely when there are cameras in their cabs monitoring their behaviour.
Computer scientists and driving psychologists from the University of Nottingham analysed data collected before and after the installation of unobtrusive cameras in the cabs of Heavy Good Vehicles (HGV) and found there is a significant reduction of risky driving behaviours with camera monitoring, and that this is even more effective when coupled with coaching. Their findings have been published in Accident Analysis and Prevention Journal.
The Northwest Sub-basin (NWSB) is an indispensable and essential part of the South China Sea (SCS) since it is one of three sub-basins of the SCS. In this paper, researchers used 11 OBSs' data along the profile OBS2006-2 (Fig. 1) by means of the latest data converting programs, elaborated the velocity structures of extinct spreading ridge by the employ of forward/inverse modeling software (RayInvr and Tomo2d), and then clarified the formation mechanism of the Double-peak seamount in the NWSB.
Strata completeness refers to "the fraction of time intervals of some specified length (t) that have been preserved". Since the 1780s, it has been widely accepted that most stratigraphic sections are riddled with gaps and are discontinuous over a range of temporal scales.
Quantum technology holds great promise: Just a few years from now, quantum computers are expected to revolutionize database searches, AI systems, and computational simulations. Today already, quantum cryptography can guarantee absolutely secure data transfer, albeit with limitations. The greatest possible compatibility with our current silicon-based electronics will be a key advantage.
"Our study is very significant for understanding how organisms, in this case the common swift, can migrate from one part of the world to another, where access to food is much better at a given time", says Susanne Åkesson, professor at Lund University and principal investigator of the study.
A recent study found strong associations between the financial holdings of legislators in the U.S. House of Representatives and how those lawmakers voted on key financial legislation. The study suggests that many lawmakers voted in ways that benefited their personal finances, regardless of whether those votes were consistent with their espoused politics.
Researchers at CRANN and the School of Physics at Trinity College Dublin have discovered that a new material can act as a super-fast magnetic switch. When struck by successive ultra-short laser pulses it exhibits "toggle switching" that could increase the capacity of the global fibre optic cable network by an order of magnitude.

New research provides a global analysis of the footprint of storm surges, providing a first step toward helping decision-makers coordinate flood management and emergency response plans across borders.
When Category 4 Hurricane Laura made landfall, the biggest cause of alarm was a projected "un-survivable" 20-foot storm surge. A storm surge is the sudden rise in sea level generated by a storm that can produce powerful currents, flood roads and destroy infrastructure.
