Depression is a serious medical condition that plagues modern society. Several theories have been proposed to explain the physiological basis of depression, of which the “neurogenic hypothesis of depression” has garnered much attention.
Back in 2,014 the World Health Organization (WHO) warned that within a decade, antibiotic-resistant bacteria could make routine surgery, organ transplantation, and cancer treatment life-threateningly risky — and spell the end of modern medicine as we know it.
Antibiotics are a cornerstone of modern medicine, used to treat infections and to protect vulnerable patients undergoing surgery or chemotherapy. The world desperately needs new antibiotics, and Covid-19 has only exacerbated the problem.

PHILADELPHIA – Treating obese mice with the cytokine known as TSLP led to significant abdominal fat and weight loss compared to controls, according to new research published Thursday in Science from researchers in the Perelman School of Medicine at the University of Pennsylvania. Unexpectedly, the fat loss was not associated with decreased food intake or faster metabolism. Instead, the researchers discovered that TSLP stimulated the immune system to release lipids through the skin’s oil-producing sebaceous glands.
“This was a completely unforeseen finding, but we’ve demonstrated that fat loss can be achieved by secreting calories from the skin in the form of energy-rich sebum,” said principal investigator Taku Kambayashi, MD, PhD, an associate professor of Pathology and Laboratory Medicine at Penn, who led the study with fourth-year medical student Ruth Choa, PhD. “We believe that we are the first group to show a non-hormonal way to induce this process, highlighting an unexpected role for the body’s immune system.”
The animal model findings, Kambayashi said, support the possibility that increasing sebum production via the immune system could be a strategy for treating obesity in people.

Bacteria may get a bad reputation in general, yet it’s actually generally healthy and serves an important role in many habitats, including human bodies. From supporting life on Earth to being employed in industrial and medicinal processes, bacteria have their figurative fingers in many pots — some varieties of bacteria can even filter tainted water and make it safe for human consumption.
A team of researchers from the Indian Institute of Technology, Banaras Hindu University (IIT-BHU) has found a bacteria that can do just that — Named “microbacterium paraoxydans strain VSVM IIT (BHU)” by the scientists, it can separate toxic hexavalent chromium from water in an effective and eco-friendly manner, according to a research published in the Journal of Environmental Chemical Engineering.
Hexavalent chromium is a heavy metal ion that is used in electroplating, welding, and chromate painting, among other things. It’s said to be responsible for health problems in humans like cancers, kidney and liver malfunctioning, and infertility. When compared to current approaches, the scientists believe that this bacterial strain, which can tolerate high amounts of hexavalent chromium, is particularly successful at eliminating the harmful substance from wastewater.
Advocates of the fat-but-fit approach to obesity treatment argue that improving fitness, even in the absence of weight loss, can help reduce the risk of cardiovascular disease and mortality.
New research suggests that improving fitness is at least as effective as weight loss for staving off obesity-related cardiovascular disease and mortality risks.
