Scientists use Doppler to peer inside cells

Doppler radar improves lives by peeking inside air masses to predict the weather. A team is using similar technology to look inside living cells, introducing a method to detect pathogens and treat infections in ways that scientists never have before.

Nuclear physicists on hunt for squeezed protons

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights into the particles that build our universe. Now, researchers hunting for these squeezed protons have come up empty-handed, suggesting there's more to the phenomenon than...

A tangled food web

Born in food web ecology, the concept of trophic levels -- the hierarchy of who eats who in the natural world -- is an elegant way to understand how biomass and energy move through a natural system. It's only natural that the idea found its way into the realm of aquaculture, where marine and freshwater farmers try to maximize their product with efficient inputs.

Rare bee found after 100 years

A widespread field search for a rare Australian native bee not recorded for almost a century has found it's been there all along - but is probably under increasing pressure to survive.

64 human genomes as new reference for global genetic diversity

20 years after the successful completion of the Human Genome Project', an international research group has now sequenced 64 human genomes at high resolution. This reference data includes individuals from around the world, better capturing the genetic diversity of the human species. Among other applications, the work enables population-specific studies on genetic predispositions to human diseases...

New signaling pathway in neurons

A new signaling pathway has been identified that can prevent the overproduction of certain RNA-protein complexes in neurons. These complexes play an important role in neurodegenerative diseases.

Post-wildfire landslides becoming more frequent in southern California

Southern California can now expect to see post-wildfire landslides occurring almost every year, with major events expected roughly every ten years, a new study finds. The results show Californians are now facing a double whammy of increased wildfire and landslide risk caused by climate change-induced shifts in the state's wet and dry seasons, according to researchers who mapped landslide...

Comet makes a pit stop near Jupiter's asteroids

After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.

Understanding the evolution of SARS and COVID-19 type viruses

As COVID-19 sweeps the world, related viruses quietly circulate among wild animals. A new study shows how SARS-CoV-2, the virus that causes COVID-19, and SARS-CoV-1, which caused the 2003 SARS outbreak, are related to each other. The work helps scientists better understand the evolution of these viruses, how they acquired the ability to infect humans and which other viruses may be poised for human...

Benefits of team building exercises jeopardized if not truly voluntary

Zoom dress up parties, tug-of-war, 'trust falls' and escape rooms - team building exercises have become the go-to tool for managers trying to increase team rapport and productivity, but unfortunately many employees resent compulsory bonding and often regard these exercises as the bane of their workplace existence.  A paper published by Sydney researchers has found participants have mixed feelings...

Openly available toolkit to help lab-based coronavirus research

During the SARS-CoV-2 outbreak, laboratories worldwide have pivoted from their usual research to working to identify new COVID-19 drug and vaccine candidates. This experimental work requires access to clinical isolates and systems that allow genetic manipulation of SARS-CoV-2. A new paper reports an openly available SARS-CoV-2 laboratory research toolkit aimed at increasing availability of these...
