Airplane wings, wind turbine blades, and other large parts are typically created using bulk polymerization in composite manufacturing facilities. They are heated and cured in enormous autoclaves and heated molds as big as the finished part. Frontal polymerization is a new out-of-autoclave method for composite manufacturing that doesn't require a large facility investment. Researchers at the University of Illinois Urbana-Champaign conducted a study pitting one process against the other to discover the pros and cons of each.
NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of Typhoon Hagupit in the Northwestern Pacific Ocean that showed the development of an eye as it quickly intensified. Imagery also showed a thick band of thunderstorms that resembled a giant tail, spiraling into the powerful storm.
Tropical Depression 03W formed northeast of Luzon, Philippines on August 1 and was renamed Hagupit when it strengthened to a tropical storm on Aug. 2. By Aug. 3, Hagupit had quickly intensified into a typhoon.
NASA's Aqua satellite obtained visible and water vapor imagery as Tropical Storm Isaias continued moving along the east coast of Florida. On Aug. 3, Warnings and Watches stretched from Florida to Maine.

As the population grows, and the global standard of living improves, humanity's appetite for seafood is increasing. In 2020 seafood consumption reached an all-time high, with an average of 20kg consumed annually by every person on the planet.
Up to now most of this was caught in the world's freshwaters and oceans. But things are changing, and today half of all seafood consumed comes from farmed sources, called aquaculture. The sector is expected to double by 2050 to supply the increasing global demand.
Biomolecular motors in cells generate unidirectional motion, consuming chemical energy gained by, for example, hydrolysis of ATP. Elucidation of the operation principle of such molecular motors, which are nature-made nanomachines composed of proteins, has attracted much attention. Single-molecule imaging, which can directly capture the motion of molecular motors, is a promising technique toward understanding the operation principle of molecular motors.
Generations of political support for sugar cultivation have helped India become the second-largest producer of sugar worldwide. Now, the country’s commitment to renewable energy could create additional benefits, like conserving natural resources and providing better nutrition to the poor.
The study, of 640 10 to 14-year-olds in India, was designed in a way that meant it was impossible to tell who had and had not kept their promise - suggesting it is not just the fear of social retaliation that makes people stick to their word.
The team of researchers included two newly appointed members of the School of Psychology at the University of Plymouth, and the study is published in the Journal of Behavioral Decision Making.
Philadelphia, August 3, 2020 - In a new study, investigators report that patients undergoing atrial fibrillation (AF) ablation, who are physically fit before the procedure, have a much higher chance of benefiting from the procedure and remaining in normal sinus rhythm. Less fit patients are rehospitalized more often, continue to use antiarrhythmic therapies longer, and have higher death rates than fitter patients.
The fields of condensed matter physics and material science are intimately linked because new physics is often discovered in materials with special arrangements of atoms. Crystals, which have repeating units of atoms in space, can have special patterns which result in exotic physical properties. Particularly exciting are materials which host multiple types of exotic properties because they give scientists the opportunity to study how those properties interact with and influence each other.
Skoltech scientists have shown that quantum enhanced machine learning can be used on quantum (as opposed to classical) data, overcoming a significant slowdown common to these applications and opening a "fertile ground to develop computational insights into quantum systems". The paper was published in the journal Physical Review A.
Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties. The team created an 11-dimensional quantum state and used it to share a secret amongst 10 parties. By using quantum tricks, the secret can only be unlocked if the parties trust one another.
A new study shows that moist heat treatment of N95 masks eliminates severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and bacteria, which would allow reuse of these scarce resources. The study is published in CMAJ (Canadian Medical Association Journal).
The researchers found that moist heat treatment (60 min, 70°C, 50% relative humidity) did not damage the mask's structure or affect function.
Philadelphia, July 31, 2020--Continuous glucose monitoring (CGM) tracks glucose levels of people with type I or type II diabetes through a device that monitors levels throughout the day. These devices improve control of blood sugar levels by alerting patients when their levels go too high or low, but patients need to use the technology consistently to derive a benefit. Previous studies have shown that youth are less likely than adults to use CGM consistently, so there is a need to identify factors that lead to long-term CGM use in youth.
Tyrosine kinases are protein enzymes that have many functions within cells, including cell signaling, growth, and division. Sometimes these enzymes can be overactive, which helps cancer cells survive and multiply. A tyrosine kinase inhibitor (TKI) is a medication given to certain acute myeloid leukemia (AML) patients to block the actions of overactive tyrosine kinases, with the ultimate goal of stopping or slowing cancer cell growth.
Epilepsy is a wide-spread neurological disorder that affects around 50 million people worldwide. It is characterized by recurrent epileptic seizures, which are sudden bursts of electrical activity in the brain. There are many different types of seizures, and a person with epilepsy can experience more than one type.
