New drug-formulation method may lead to smaller pills

Posted: 07 Jun 2021 05:22 PM PDT

Chemical engineers have devised a simpler process for incorporating hydrophobic drugs into tablets or other drug formulations, using nanoemulsions. With this method, it may be possible to make many pills smaller and easier to swallow.

A breakthrough in the physics of blood clotting

Posted: 07 Jun 2021 05:22 PM PDT

Understanding the physics of clot contraction could potentially lead to new ways to treat bleeding problems and clotting problems.

Stabilizing gassy electrolytes could make ultra-low temperature batteries safer

Posted: 07 Jun 2021 05:22 PM PDT

A new technology could dramatically improve the safety and performance of lithium-ion batteries that operate with gas electrolytes at ultra-low temperatures. By keeping electrolytes from vaporizing, the technology can prevent pressure buildup inside the battery that leads to swelling and explosions.

Innovative batteries put flying cars on the horizon

Posted: 07 Jun 2021 01:12 PM PDT

Jet packs, robot maids and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing (eVTOL) vehicles and designing and testing potential battery power sources.

Physicists report definitive evidence how auroras are created

Posted: 07 Jun 2021 01:11 PM PDT

Physicistsreport definitive evidence of how auroras are created. In experiments, the physicists demonstrated the physical mechanisms for the acceleration of electrons by Alfven waves under conditions corresponding to Earth's auroral magnetosphere.

The origin of the first structures formed in galaxies like the Milky Way identified

Posted: 07 Jun 2021 01:10 PM PDT

An international team of scientists has used the Gran Telescopio Canarias (GTC) to study a representative sample of galaxies, both disc and spheroidal, in a deep sky zone in the constellation of the Great Bear to characterize the properties of the stellar populations of galactic bulges.

Lighting up ultrafast magnetism in a metal oxide

Posted: 07 Jun 2021 01:10 PM PDT

Understanding how magnetic correlations change over short timescales is the first step in being able to control magnetism for applications.

A quantum step to a heat switch with no moving parts

Posted: 07 Jun 2021 01:10 PM PDT

Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy -- and in the process identified a promising material for future devices that could turn heat on and off with the application of a magnetic 'switch.'

Lead halide perovskites -- a horse of a different color

Posted: 07 Jun 2021 01:10 PM PDT

Researchers have developed a novel spectroscopic technique for the study of charge carrier dynamics in lead halide perovskites.

Axions could be the fossil of the universe researchers have been waiting for

Posted: 07 Jun 2021 08:02 AM PDT

No one knows what happened in the universe for its first 400,000 years, but a new paper suggests discovering the hypothetical particle axion could shed light on the early history of the universe. What's more, current dark matter experiments may have already detected it in its data.

How coronavirus aerosols travel through our lungs

Posted: 07 Jun 2021 08:02 AM PDT

When we inhale isolated coronavirus particles, more than 65 percent reach the deepest region of our lungs, new research has discovered, and more of these aerosols reach the right lung than the left.

Applying mathematics takes 'friendship paradox' beyond averages

Posted: 07 Jun 2021 05:46 AM PDT

In network science, the famous 'friendship paradox' describes why your friends are (on average) more popular, richer, and more attractive than you are. But a slightly more nuanced picture emerges when we apply mathematics to real-world data.

How a Vietnamese raw pork snack could help us keep food fresh, naturally

Posted: 07 Jun 2021 05:46 AM PDT

Nem Chua is eaten raw but doesn't cause food poisoning when prepared correctly. Food scientists went to explore why - and discovered a powerful new bacteria-killer. A new study reveals the ideal growth conditions to potentially make the bacteriocin at industrial scales.

Controlling insulin production with a smartwatch

Posted: 07 Jun 2021 05:46 AM PDT

Researchers have developed a gene switch that can be operated with the green LED light emitted by commercial smartwatches. This revolutionary approach could be used to treat diabetes in the future.
