A team of biology researchers from Universität der Bundeswehr, Technische Universität München and the University of Cassino and Southern Lazio, has found that people exhale more aerosols when engaging in endurance exercise than they do when engaging in resistance exercise. The study is published in the Proceedings of the National Academy of Sciences.

As the global pandemic has progressed, scientists across the globe have studied various aspects of the SARS-CoV-2 virus spread. One such area of study has been comparison of types of activities that are more or less conducive to transmission of the virus.

In this new study, the researchers looked at exercise options and their related risk. Going to gyms to exercise is a popular way to keep in shape. But doing so can put people at risk from both airborne and surface viral and bacterial infections.

When a person experiences a happy or sad mood, which brain cells are active?

To answer that question, scientists need to understand how individual brain cells contribute to a larger network of brain activity and what role each cell plays in shaping behavior and overall health. Until now, it’s been difficult to get a clear view of how brain cells in living animals behave over extended periods of time.

But Jia Liu’s group at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has developed an electronic implant that collected detailed information about brain activity from a single cell of interest for more than a year. Their findings, based on research in mice, are reported in Nature Neuroscience.

Psyllium fiber protects against ulcerative colitis and suppresses inflammation by activating the bile acid nuclear receptor, a mechanism that was previously unrecognized, according to a new study by researchers in the Institute for Biomedical Sciences at Georgia State University.

The findings published in the journal Cellular and Molecular Gastroenterology and Hepatology (CMGH) reveal that psyllium, which is semi-soluble and derived from Plantago seeds, inhibits inflammation that can lead to colitis in mice by increasing serum bile acids, resulting in the activation of the farnesoid X receptor (FXR), a bile acid nuclear receptor.

Fiber-rich foods promote intestinal and metabolic health, but the extent of protection varies for each fiber type and the mechanisms that offer this protection are poorly defined. It has been unclear whether dietary fiber can benefit severe forms of intestinal inflammation, such as Crohn’s disease and ulcerative colitis, which are collectively known as inflammatory bowel disease (IBD) and affect 3 million adults in the United States.

Whether it is steamed idli, Gujarati snack, panki; Parsi’s patra ni machchi, Assam’s bhapot diya maach or the elaborate Onam Sandhya from Kerala, the humble banana leaf has found its way into many cuisines.

It is also very versatile as food can be steamed, grilled and deep-fried. It can also be used as a serving plate and packaging material.

While banana leaves have been an integral part of the desi food and traditions, did you know there are health benefits to it as well?

Step one for uploading your brain after the singularity… keep it cognitively functional until then.

It’s been estimated that one in three cases of dementia is preventable. You can’t do anything right now to stop or reverse the underlying mechanisms of Alzheimer’s disease, but you can do something about hypertension and vascular disease risk factors.

Scientists at the University of Massachusetts Amherst recently announced the invention of a nanowire, 10,000 times thinner than a human hair, which can be cheaply grown by common bacteria and can be tuned to “smell” a vast array of chemical tracers—including those given off by people afflicted with different medical conditions, such as asthma and kidney disease.

Thousands of these specially tuned wires, each sniffing out a different chemical, can be layered onto tiny, wearable sensors, allowing health-care providers an unprecedented tool for monitoring potential health complications. Since these wires are grown by bacteria, they are organic, biodegradable and far greener than any inorganic nanowire.

To make these breakthroughs, which were detailed in the journal Biosensors and Bioelectrics, senior authors Derek Lovley, Distinguished Professor of Microbiology at UMass Amherst, and Jun Yao, professor of electrical and computer engineering in the College of Engineering at UMass Amherst, needed to look no farther than their own noses.

New textiles developed at Aalto University change shape when they heat up, giving designers a wide range of new options. In addition to offering adjustable esthetics, responsive smart fabrics could also help monitor people’s health, improve thermal insulation, and provide new tools for managing room acoustics and interior design.

The new fabrics weave together old technology and a new approach. Liquid crystalline elastomers (LCEs) were developed in the 1980s. LCEs are a smart material that can respond to heat, light, or other stimuli, and they’ve been used as thin films in soft robotics. Although LCEs have been made into fibers, so far they haven’t been made into textiles.
