Swimming without brains and muscles
- ScienceDaily
- 22/7/29 23:32
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
- ScienceDaily
- 22/7/29 23:32
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
- ScienceDaily
- 22/7/29 23:32
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
- ScienceDaily
- 22/7/29 23:32
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
- ScienceDaily
- 22/7/29 23:32
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.
A stable gut helps elite athletes perform better
- ScienceDaily
- 22/7/29 23:32
New research has found that microbial instability in the gut could hinder the performance of elite endurance athletes, and that short-term, high-protein diets are associated with this type of imbalance.
New DNA repair-kit successfully fixes hereditary disease in patient-derived cells
- ScienceDaily
- 22/7/29 23:32
Genetic mutations which cause a debilitating hereditary kidney disease affecting children and young adults have been fixed in patient-derived kidney cells using a potentially game-changing DNA repair-kit.
Plant-based 'meat' 'healthier and more sustainable than animal products'
- ScienceDaily
- 22/7/29 23:32
A new review focuses on the health and environmental benefits of plant-based products, as well as consumer attitudes.
It doesn't matter much which fiber you choose -- just get more fiber!
- ScienceDaily
- 22/7/29 23:32
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...
Advanced imaging reveals mired migration of neurons in Rett syndrome lab models
- ScienceDaily
- 22/7/29 23:31
Using organoids to model early development, researchers used an emerging microscopy technology to see that new neurons struggled to reach their developmental destination.
Pinpointing consciousness in animal brain using mouse 'brain map'
- ScienceDaily
- 22/7/29 23:31
Science may be one step closer to understanding where consciousness resides in the brain. A new study shows the importance of certain types of neural connections in identifying consciousness.
New breath-driven concept set to transform access to hand prosthetics
- ScienceDaily
- 22/7/29 23:31
The new air-powered hand provides a lightweight, low-maintenance and easy-to-use body-powered prosthetic option particularly well suited for children and those in low and middle-income countries.
Interplay of ancestry and sexual dimorphism significantly affect growth patterns in frontal sinuses, researchers find
- ScienceDaily
- 22/7/29 23:31
Researchers have found the development of the frontal sinus was affected more by sexual dimorphism than the ancestry of the individual and that it was the interplay between those two factors that produced the most significant variation.
Taking your time makes a difference

Cells in the gut send secret messages to the immune system. Thanks to new research, we can finally get a look at what they're saying.
Putting a positive spin on the Buckyball C60
- ScienceDaily
- 22/7/29 16:24
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.
