Swimming without brains and muscles

Bacteria and other unicellular organisms developed sophisticated ways to actively navigate their way, despite being comparably simple structures. To reveal these mechanisms, researchers used oil droplets as a model for biological microswimmers. Biologists investigated the navigation strategies of microswimmers in several studies: how they navigate against the current in narrow channels, how they...

Communication makes hunting easier for chimpanzees

Similar to humans, chimpanzees use communication to coordinate their cooperative behavior -- such as during hunting. When chimpanzees produce a specific vocalization, known as the 'hunting bark', they recruit more group members to the hunt and capture their prey more effectively, researchers have now shown.

Space travel: Bone aging in fast forward

Long periods in space damage bone structure irreparably in some cases and can make parts of the human skeleton age prematurely by up to 10 years, according to new research. Adapted training programs in conjunction with medication could provide better protection for astronauts on future space missions. The research findings also have implications for treating rheumatic conditions in clinical...

Technique for the isolation of volatile food compounds optimized

A research team has succeeded in automating an established method for the gentle, artifact-avoiding isolation of volatile food ingredients. As the team's current comparative study now shows, automated solvent-assisted flavor evaporation (aSAFE) offers significant advantages over the manual process. It achieves higher yields on average and reduces the risk of contamination by nonvolatile...

A paper battery with water switch

A team of researchers has developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics -- such as smart labels for tracking objects, environmental sensors and medical diagnostic devices -- and minimize their environmental impact.

It doesn't matter much which fiber you choose -- just get more fiber!

The benefit of dietary fiber isn't just the easier pooping that advertisers tout. Fermentable fiber is an essential source of nutrients that your gut microbes and cells of the intestines need to stay healthy. Study participants who had been eating the least amount of fiber before being fed three different kinds of fiber supplement showed the greatest benefit from supplements, regardless of which...

Taking your time makes a difference

Researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.

Putting a positive spin on the Buckyball C60

Researchers have identified highly ionized species of the famous soccer ball-shaped 'Buckminsterfullerene' C60 molecule as plausible carriers of at least some of the most prominent and enigmatic Unidentified Infrared Emission (UIE) bands that have challenged astronomers since they were first discovered and studied over 30 years ago.

New bioremediation material to clean up 'forever chemicals'

A novel bioremediation technology for cleaning up per- and polyfluoroalkyl substances, or PFAS, chemical pollutants that threaten human health and ecosystem sustainability, has been developed. The material has potential for commercial application for disposing of PFAS, also known as 'forever chemicals.'

Listening to the people results in a more sustainable future energy system

By taking into account the demographics and preferences of US racial groups, clarified through a nationally representative survey of 3,000 US residents, researchers have created a 'desirable' electricity generation mix for 2050 that includes 50% more energy from renewables than current projections. Combining such bottom-up input with top-down energy system goals set by policymakers could help meet...
