Effect of odor on helpfulness in rats
- ScienceDaily
- 20/11/25 22:44
Despite their reputation, rats are surprisingly sociable and regularly help each other out. Researchers have shown that a rat just has to smell another rat that is engaged in helpful behavior to increase their own helpfulness. This is the first study to show that just the smell of a cooperating rat is enough to trigger a helpful response.

- 20/11/25 21:48
Researchers have discovered how Rubisco holoenzymes assemble to form the fluid-like matrix of the algal pyrenoid, an organelle that mediates the incorporation of carbon dioxide into sugars.
Specific bacterium in the gut linked to irritable bowel syndrome (IBS)
- ScienceDaily
- 20/11/25 19:51
Researchers have detected a connection between Brachyspira, a genus of bacteria in the intestines, and IBS -- especially the form that causes diarrhea. Although the discovery needs confirmation in larger studies, there is hope that it might lead to new remedies for many people with irritable bowel syndrome.
Quantum nanodiamonds may help detect disease earlier

For the first time, the international team was able to directly observe neutrinos from this cycle (CNO neutrinos).
New study explains important cause of fatal influenza
- ScienceDaily
- 20/11/25 18:23
It is largely unknown why influenza infections lead to an increased risk of bacterial pneumonia. Researchers have now described important findings leading to so-called superinfections, which claim many lives around the world every year.
A microscope for everyone: Researchers develop open-source optical toolbox
- ScienceDaily
- 20/11/25 18:23
Researchers have developed an optical toolbox to build microscopes for a few hundred euros that deliver high-resolution images comparable to commercial microscopes that cost up to a thousand times more. The 3D printed open-source modular system can be combined in the way the research question requires -- from the observation of living organisms in the incubator to a toolbox for education.
Novel haplotype-led approach to increase the precision of wheat breeding

Wheat researchers are pioneering a new technique that promises to improve gene discovery for the globally important crop.
Researchers uncover the unique way stem cells protect their chromosome ends
- ScienceDaily
- 20/11/25 18:23
Telomeres are specialized structures at the end of chromosomes which protect our DNA and ensure healthy division of cells. According to a new study, the mechanisms of telomere protection are surprisingly unique in stem cells.
Ice sheets on the move: How north and south poles connect
- ScienceDaily
- 20/11/25 17:44
Over the past 40,000 years, ice sheets thousands of kilometers apart have influenced one another through sea level changes, according to new research. New modelling of ice sheet changes during the most recent glacial cycle demonstrates, for the first time, that during this period, changes in the Antarctic ice sheet were driven by the melting ice sheets in the Northern Hemisphere.
New insights on health effects of long-duration space flight
- ScienceDaily
- 20/11/25 17:44
Among the new findings, the research team found that chronic oxidative stress during spaceflight contributed to the telomere elongation they observed. They also found that astronauts had shorter telomeres after spaceflight than they did before.
Space travel can adversely impact energy production in a cell
- ScienceDaily
- 20/11/25 17:44
Studies of both mice and humans who have traveled into space reveal that critical parts of a cell's energy production machinery, the mitochondria, can be made dysfunctional due to changes in gravity, radiation exposure and other factors. These findings are part of an extensive research effort across many scientific disciplines to look at the health effects of travel into space.
