Brown fat is that magical tissue that you would want more of. Unlike white fat, which stores calories, brown fat burns energy and scientists hope it may hold the key to new obesity treatments. But it has long been unclear whether people with ample brown fat truly enjoy better health. For one thing, it has been hard to even identify such individuals since brown fat is hidden deep inside the body.

Now, a new study in Nature Medicine offers strong evidence: among over 52000 participants, those who had detectable were less likely than their peers to suffer cardiac and metabolic conditions ranging from type 2 diabetes to , which is the leading cause of death in the United States.

The study, by far the largest of its kind in humans, confirms and expands the health benefits of brown fat suggested by previous studies. “For the first time, it reveals a link to lower risk of certain conditions,” says Paul Cohen, the Albert Resnick, M.D., Assistant Professor and senior attending physician at The Rockefeller University Hospital. “These findings make us more confident about the potential of targeting brown fat for therapeutic benefit.”

The enormous impact of the recent COVID-19 pandemic, together with other diseases or chronic health risks, has significantly prompted the development and application of bioelectronics and medical devices for real-time monitoring and diagnosing health status. Among all these devices, smart contact lenses attract extensive interests due to their capability of directly monitoring physiological and ambient information. Smart contact lenses equipped with high sensitivity sensors would open the possibility of a non-invasive method to continuously detect biomarkers in tears. They could also be equipped with application-specific integrated circuit chips to further enrich their functionality to obtain, process and transmit physiological properties, manage illnesses and health risks, and finally promote health and wellbeing. Despite significant efforts, previous demonstrations still need multistep integration processes with limited detection sensitivity and mechanical biocompatibility.

Recently, researchers from the University of Surrey, National Physical Laboratory (NPL), Harvard University, University of Science and Technology of China, Zhejiang University Ningbo Research Institute, etc. have developed a multifunctional ultrathin contact sensor system. The sensor systems contain a photodetector for receiving optical information, imaging and vision assistance, a temperature sensor for diagnosing potential corneal disease, and a glucose sensor for monitoring glucose level directly from the tear fluid.

Dr. Yunlong Zhao, Lecturer in Energy Storage and Bioelectronics at the Advanced Technology Institute (ATI), University of Surrey and Senior Research Scientist at the UK National Physical Laboratory (NPL), who led this research stated, “These results provide not only a novel and easy-to-make method for manufacturing advanced smart contact lenses but also a novel insight of designing other multifunctional electronics for Internet of Things, , etc.” Dr. Zhao added, “our ultrathin transistors-based serpentine mesh sensor system and fabrication strategy allow for further incorporation of other functional components, such as electrode array for electrophysiology, antennas for wireless communication, and the power modules, e.g. thin-film batteries and enzymatic biofuel cell for future in vivo exploration and practical application. Our research team at ATI, University of Surrey and NPL are currently working on these fields.”

When taken orally or intravenously, medications typically travel throughout the body, producing unwanted side effects. MIT scientists are working on an alternative, that delivers both light and a light-activated drug directly to the target area.

So-called “photoswitchable” drugs contain light-sensitive molecules that essentially switch the drug on when exposed to a flash of light. This means that a pharmaceutical could remain inactive when moving through the bloodstream or digestive tract, only becoming active once it reached the place it was needed. As a result, few if any side effects would occur.

That said, how could a flash of light be delivered precisely to the target area, right when the drug was present at that location? Well, that’s where a device developed by the MIT researchers comes into play.

Scientists have developed a machine-learning method that crunches massive amounts of data to help determine which existing medications could improve outcomes in diseases for which they are not prescribed.

The intent of this work is to speed up repurposing, which is not a new concept—think Botox injections, first approved to treat crossed eyes and now a migraine treatment and top cosmetic strategy to reduce the appearance of wrinkles.

But getting to those new uses typically involves a mix of serendipity and time-consuming and expensive randomized to ensure that a drug deemed effective for one disorder will be useful as a treatment for something else.

Proteins are essential to cells, carrying out complex tasks and catalyzing chemical reactions. Scientists and engineers have long sought to harness this power by designing artificial proteins that can perform new tasks, like treat disease, capture carbon or harvest energy, but many of the processes designed to create such proteins are slow and complex, with a high failure rate.

In a breakthrough that could have implications across the healthcare, agriculture, and energy sectors, a team lead by researchers in the Pritzker School of Molecular Engineering at the University of Chicago has developed an artificial intelligence-led process that uses big data to design new proteins.

By developing machine-learning models that can review protein information culled from genome databases, the researchers found relatively simple design rules for building artificial proteins. When the team constructed these artificial proteins in the lab, they found that they performed chemical processes so well that they rivaled those found in nature.

The world is far from perfect, and 2020 did throw the proverbial spanner is the works, but the improvements we have made are not to be ignored!!

We are winning…

I will review the lesser shared news the world is not as bad as you might have been led to believe, even if it is not yet perfect.

We think our approach — which is backed up by several techniques, including single-cell RNA-sequencing analysis — is a significant step toward bringing SSC therapy into the clinic, Miles Wilkinson, an obstetrics, gynecology, and reproductive sciences researcher at the University of California, San Diego School of Medicine, said in a press release.

SSCs can generate more stem cells and as many as 1, 000 sperm every couple of seconds — but until this new study, published Monday in the journal PNAS, scientists were unable to differentiate and isolate SSCs from other, similar cells in the testicles.

Next, our main goal is to learn how to maintain and expand human SSCs longer so they might be clinically useful, Wilkinson said in the release.
