Research captures how human sperm swim in 3D

Using a high-speed camera capable of recording over 8,000 frames in one second, and a microscope stage with a piezoelectric device to move the sample up and down at an incredibly high rate, they were able to scan the sperm swimming freely in 3D. "Human sperm roll as they

'AeroNabs' promise powerful, inhalable protection against COVID-19

Led by UCSF graduate student Michael Schoof, a team of researchers engineered a completely synthetic, production-ready molecule that straitjackets the crucial SARS-CoV-2 machinery that allows the virus to infect our cells. As reported in a new paper, now available on the preprint server bioRxiv, experiments using live virus show that

Inexpensive, accessible device provides visual proof that masks block droplets: Study demonstrates a simple way to test facial covering materials for effectiveness

But he needed to know whether the virus-blocking claims mask suppliers made were true, to assure he wasn't providing ineffective masks that spread viruses along with false security.

COVID-19 lockdown caused 50 percent global reduction in human-linked Earth vibrations

This quiet period, likely caused by the total global effect of social distancing measures, closure of services and industry, and drops in tourism and travel, is the longest and most pronounced quiet period of seismic noise in recorded history. The new research, led by the Royal Observatory of Belgium and

Plato was right: Earth is made, on average, of cubes: The ancient Greek philosopher was on to something, researchers found

Science has steadily moved beyond Plato's conjectures, looking instead to the atom as the building block of the universe.Yet Plato seems to have been onto something, researchers have found.

Researchers convert female mosquitoes to nonbiting males with implications for mosquito control

Male mosquitoes do not bite and are unable to transmit pathogens to humans.Female mosquitoes, on the other hand, are able to bite.

'Little brain' or cerebellum not so little after all

Sometimes referred to by its Latin translation as the '"little brain"', the cerebellum is located close to the brainstem and sits under the cortex in the hindbrain.

Study sheds light on the evolution of the earliest dinosaurs

In 2017, however, this classical view of dinosaur evolution was thrown into question with evidence that perhaps the lizard-hipped dinosaurs evolved first -- a finding that dramatically rearranged the first major branches of the dinosaur family tree. Now an MIT geochronologist, along with paleontologists from Argentina and Brazil, has found

New blood test shows great promise in the diagnosis of Alzheimer's disease

For many years, the diagnosis of Alzheimer's has been based on the characterization of amyloid plaques and tau tangles in the brain, typically after a person dies.

Vikings had smallpox and may have helped spread the world's deadliest virus

Smallpox spread from person to person via infectious droplets, killed around a third of sufferers and left another third permanently scarred or blind.

Centenarian study suggests living environment may be key to longevity

Published in the International Journal of Environmental Research and Public Health and based on Washington State mortality data, the research team's findings suggest that Washingtonians who live in highly walkable, mixed-age communities may be more likely to live to their 100th birthday. They also found socioeconomic status to be correlated,

The Entropic Brain: The Neuroscience of Psychedelic States

In recent years there has been an explosion in the number of experiments on psychedelics, with hundreds of brain scans done on tripping participants—all in the name of science.

Using A Smart Phone Can Cause Structural Differences In Your Brain

A new study recently published by German researchers from Heidelberg University show differences in brain structure between people with 'smart phone addition' compared to people without it.

Reproducibility in cognitive hearing research: Theoretical considerations and their practical application in multi-lab studies

In this article, we consider the issue of reproducibility within the field of cognitive hearing science.
