Scientists part of team that points to strong connection between climate change, plastics pollution

At the root of global climate change and the worldwide plastics problem are two related carbon-based fuels -- oil and natural gas. Not only are the two among the key drivers of climate change, they are instrumental in the manufacturing of plastics. As storms intensify and become more frequent, the movement of trash from land to our oceans and, and vice versa, is only going to get worse.

Bat study reveals secrets of the social brain

Neuroscientists used wireless devices to record the neural activity of freely interacting Egyptian fruit bats, providing researchers with the first glimpse into how the brains of social mammals process complex group interactions.

Shape-shifting materials with infinite possibilities

Researchers have developed a shape-shifting material that can take and hold any possible shape, paving the way for a new type of multifunctional material that could be used in a range of applications, from robotics and biotechnology to architecture.

On the hunt for hypernuclei: The WASA detector at GSI/FAIR

With the WASA detector, a very special instrument is currently being set up at GSI/FAIR. Together with the fragment separator FRS, it will be used to produce and study so-called hypernuclei during the upcoming experiment period of FAIR Phase 0 in 2022. For this purpose, the assembly, which weighs several tons, is being transferred to the facility in a complex installation procedure.

How pearls achieve nanoscale precision

In research that could inform future high-performance nanomaterials, a study has uncovered how mollusks build ultradurable structures with a level of symmetry that outstrips everything else in the natural world, with the exception of individual atoms.

Modeling cellular migration

A new model sheds light on the function of a protein that is a major player in cancer growth, and their results could one day help researchers determine better ways to stop the spread of cancer.

Novel peroxide-based material emits fluorescence in response to stress

A new organic peroxide molecule, BMPF releases fluorescence under mechanical stress and could be incorporated into polymer networks for mechanofunctional design. BMPF-linked polymers are also stable at relatively high temperatures and could pave the way for highly selective and efficient small-molecule-releasing systems with applications in imaging and drug delivery.

Breaking trade-off problem that limits thermoelectric conversion efficiency of waste heat

Scientists demonstrate that breaking the trade-off problem between thermopower and conductivity improves thermoelectric performance. They suggest introducing lattice strain into Mott insulator oxide LaTiO3 converts the electronic state to metal, and increases both thermopower and conductivity to induce a 100-fold increase in power factor, which in turn enables the conversion of waste heat to...

Astronomers provide 'field guide' to exoplanets known as hot Jupiters

By combining Hubble Space Telescope observations with theoretical models, a team of astronomers has gained insights into the chemical and physical makeup of a variety of exoplanets known as hot Jupiters. The findings provide a new and improved 'field guide' for this group of planets and inform ideas about planet formation in general.

New photonic chip for isolating light may be key to miniaturizing quantum devices

Light plays a critical role in enabling 21st century quantum information applications. Limited by size, engineers need to miniaturize quantum devices, which requires re-thinking certain components for harnessing light. Researchers have designed a simple, compact photonic circuit that uses sound waves to rein in light. The team's measurements show that their approach to isolation currently...

Two beams are better than one

History's greatest couples rely on communication to make them so strong their power cannot be denied. But that's not just true for people, it's also true for lasers. According to new research from the USC Viterbi School of Engineering, adding two lasers together as a sort of optical 'it couple' promises to make wireless communications faster and more secure than ever before.

It's not all-right: Problems when your body doesn't recognize your own left-handed RNA

By generating a specific mutation in lab mice, researchers determined that a protein domain in an enzyme called adenosine deaminase 1 p150 is necessary for binding and editing certain RNA molecules. Mutant mice showed inhibited growth after birth, as well as abnormally developed organs. Interestingly, their brains showed characteristics similar to encephalopathy seen in humans suffering from...

Researchers target tumors with intracellular precision

A non-toxic, bacteria-based system can detect when it is inside a cancer cell and then release its payload of therapeutic drugs directly into the cell. The work could lead to effective, targeted therapies for currently untreatable cancers, such as liver or metastatic breast cancer.

How staphylococci protect themselves against antibiotics

The skin bacterium Staphylococcus aureus often develops antibiotic resistance. It can then cause infections that are difficult to treat. Researchers have now uncovered an ingenious way in which a certain strain of Staphylococcus aureus protects itself against the important antibiotic vancomycin.
