Summary: A new study aims to investigate the interaction between the digestive and nervous systems, or the gut-brain axis, to discover more about the links between digestive health and neurodegenerative diseases.

How do the gut and the brain interact, and can this even trigger disease?
The oral and skin care brand has already undertaken two other experiments on the space station.
Colgate-Palmolive Company and NASA have entered into a partnership to explore innovative solutions to advance oral health, personal care and skin health for astronauts and even populations on earth, according to a press release by the self-care company published on Wednesday.
The deal will see former astronaut Dr. Cady Coleman join the team as an advisor for the experiments conducted.
An analysis of 22 large-scale gene expression datasets pointed to exercise and activity in general as the most effective theoretical treatment for reversing gene expressions typical of Alzheimer’s disease. Fluoxetine, a well-known antidepressant, also showed effect, particularly when combined with exercise. Curcumin showed positive effects as well. The study was published in Scientific Reports.
Alzheimer’s disease is a complex neurodegenerative disorder that affects multiple brain regions. It is the most common disease that causes dementia and is very difficult to treat. In the course of the disease, abnormal collections of proteins called tau accumulate inside neurons.
Another type of protein clumps together to form so-called amyloid plaques that collect between neurons and disrupt cell functions. These and other changes harm the functioning of the brain across different regions and lead to dysfunction and death of brain cells.
Cambridge scientists have created a comprehensive tool for predicting an individual’s risk of developing prostate cancer, which they say could help ensure that those men at greatest risk will receive the appropriate testing while reducing unnecessary—and potentially invasive—testing for those at very low risk.
CanRisk-Prostate, developed by researchers at the University of Cambridge and The Institute of Cancer Research, London, will be incorporated into the group’s CanRisk web tool, which has now recorded almost 1.2 million risk predictions. The free tool is already used by health care professionals worldwide to help predict the risk of developing breast and ovarian cancers.
Prostate cancer is the most common type of cancer in men. According to Cancer Research UK, more than 52,000 men are diagnosed with the disease each year and there are more than 12,000 deaths. Over three-quarters (78%) of men diagnosed with prostate cancer survive for over ten years, but this proportion has barely changed over the past decade in the U.K.
The experiment is a collaboration between the University of Cambridge and Université Libre de Bruxelles – partner institutions of the European Commission’s Graphene Flagship – along with the Mohammed bin Rashid Space Centre (MBRSC) in the United Arab Emirates, York University in Canada, and the European Space Agency (ESA).
Regolith is composed of extremely sharp, tiny and sticky grains and, since the Apollo missions, it has been one of the biggest challenges lunar missions have had to overcome. Regolith can cause mechanical and electrostatic damage to equipment and is therefore also hazardous for astronauts. It clogs spacesuits’ joints, obscures visors, erodes spacesuits and protective layers, and is a potential health hazard.
Cambridge researchers have produced special graphene composites that are meant to reduce regolith adhesion. The graphene samples will be monitored via an optical camera, which will record footage throughout the mission. Researchers from Université Libre de Bruxelles (ULB) will gather information during the mission and suggest adjustments to the path and orientation of the rover. Data and images obtained will be used to study the effects of the moon environment and the regolith abrasive stresses on the samples.
Earth has been hit by an intense, unusual blast of light that could change our understanding of the universe, scientists have said.
Late last year, scientists spotted a 50-second-long blast of energy coming towards Earth, known as a gamma-ray burst or GRB, which are the most powerful explosions in the universe. Immediately, researchers started looking for the afterglow that such blasts leave behind, with that visible light being useful to find where the blast has come from.
For millennia, humans have been harnessing #microbes to produce everything from breads, to cheeses, to alcohol. Now these tiny organisms have produced another powerful revolution — the gene editing tool CRISPR. Rodolphe Barrangou, Ph.D., was working at the food company Danisco, where he was trying to produce yogurt lines resistant to contamination. In a series of groundbreaking experiments, he helped uncover what CRISPR was, how it worked, and why it could be so transformative.
Good Morning, 2033 — A Sci-Fi Short Film.
What will your average morning look like in 2033? And who hacked us?
While studying how bio-inspired materials might inform the design of next-generation computers, scientists at the Department of Energy’s Oak Ridge National Laboratory achieved a first-of-its-kind result that could have big implications for both edge computing and human health.
Results published in Proceedings of the National Academy of Sciences show that an artificial cell membrane is capable of long-term potentiation, or LTP, a hallmark of biological learning and memory. This is the first evidence that a cell membrane alone—without proteins or other biomolecules embedded within it—is capable of LTP that persists for many hours. It is also the first identified nanoscale structure in which memory can be encoded.
“When facilities were shut down as a result of COVID, this led us to pivot away from our usual membrane research,” said John Katsaras, a biophysicist in ORNL’s Neutron Sciences Directorate specializing in neutron scattering and the study of biological membranes at ORNL.

How soon will we be seeing robots walking about the street? How soon will robots join medical staff in hospitals and aid real people in life or death situations? How soon will robots replace health staff? The World Health Organization (WHO) estimates that we will see a global shortfall of 12 million health workers by 2025.
From lifting patients and delivering lab samples, to cleaning and providing companionship, care robots can help with a range of tasks across a hospital or care setting. With nurses spending up to a third of their shift on menial tasks such as collecting equipment, the expectation is that care robots will be able to take ownership of these more mundane jobs, letting health staff focus on more important tasks.
