Nanodiamonds are 2–8 nm carbon nanoparticles, which can be easily functionalized with various chemical groups like carboxylic groups or drugs. Previous research has shown that actively dividing cells are more likely to absorb nanodiamonds and that epithelial cells treated with carboxylic nanodiamonds lose the ability to migrate across...

Biological computing machines, such as micro and nano-implants that can collect important information inside the human body, are transforming medicine. Yet, networking them for communication has proven challenging. Now, a global team, including EPFL researchers, has developed a protocol that enables a molecular network with multiple...

Antimicrobial resistance (AMR) directly causes an estimated 1.3 million deaths around the globe annually. A leading cause of AMR is the misuse and overuse of antibiotics, which has allowed microbes to mutate over time and develop insensitivity to the drugs designed to kill them, making infections harder to treat and increasing the risk of disease...

Bacteria that can convert nitrogen gas to ammonia could not only provide nutrients that plants need, but also help regenerate soil and protect plants from pests. However, these bacteria are sensitive to heat and humidity, so it's difficult to scale up their manufacture and ship them to farms. To overcome that obstacle, MIT chemical engineers...

An airborne fraction of soil, or dust, contains biological and chemical "signatures" that act as a fingerprint to a specific location. Australian forensic science experts, led by Flinders University, have highlighted the usefulness of the latest technology by testing a series of field sites in South Australia for their unique chemical and...

A team led by scientists at Rensselaer Polytechnic Institute has 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important role in skin healing and function. The research, published in the journal Science Advances, has...

As the aging population around the world grows, metabolic diseases like osteoporosis are becoming more prevalent and placing a greater burden on health care systems. Rising to this challenge, a research team led by Prof. Wong Ka-hing, Director of the Research Institute for Future Food and Professor of the Department of Food Science and Nutrition...

Researchers at Tampere University have been involved in an international study to develop new tools for the light-activated control of cells. These tools are especially welcome for understanding processes where a fast initial signal leads to long-term changes in cell or tissue function. The modular Lego brick-like structure makes the tools widely...

Rather than the evocative plants and animals of the Galapagos Islands that Darwin studied in forming his theory of evolution, Postdoctoral Scholar Joshua Borin and Associate Professor Justin Meyer of UC San Diego's School of Biological Sciences are documenting rapid evolutionary processes in simple laboratory flasks. Borin and Meyer set bacteria...

Ordinarily, when treating chronic wounds, caregivers go to great lengths to keep them free of bacteria. An experimental new dressing, however, actually introduces bacteria to help such wounds heal. When a diabetic skin ulcer or other chronic wound becomes infected, colonies of the problematic bacteria within it form a layer of mucus known as a...
