There's a belief that says exposing people -- especially babies and young children -- to different kinds of germs early in life can keep them from developing illnesses like asthma, allergies, and other diseases that affect the immune system. The theory, called the “hygiene hypothesis,” is that o... Read More
Whether inhabiting soil, fresh water, or marine ecosystems, bacteria are constantly facing the threat of numerous and effective predators such as protists, nematodes, or phages. To defend against such predation, bacteria have evolved a number of strategies, including getting larger in size, movi... Read More
A new biological treatment could help dairy cattle stave off uterine diseases and eventually may help improve food safety for humans, a University of Florida study shows.
Kwang Cheol Jeong, an assistant professor in animal sciences and UF’s Emerging Pathogens Institute, examined cattle uterin... Read More
Scientists regularly tap into biological systems to find solutions for human problems. Although they work with plants and viruses in the lab, bacteria have many advantages as a starting point. When programmed in certain ways, bacteria can store data, clean dangerous waste, produce film-like imag... Read More
The risk of dengue fever beginning to spread in Europe is imminent. According to researchers from Umeå University, this is no longer just an issue for the scientific community but also for politicians and policy makers, who need to be prepared and develop preventive measures.
With a changing ... Read More
The delightful word 'oocyan' refers to the trait of blue-green eggshell color that occurs in native chickens of Chile (Mapuche fowl) and some of their descendants in North America and Europe, as well as certain Asian chicken breeds (e.g. Dongxiang, Lushi).
Oocyan is an autosomal dominant trai... Read More
Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University are revealing how they do it, and perhaps opening ways to imitate them.

Methicillin-resistant S. aureus (MRSA) constitutes approximately 50% of clinical S. aureus isolates and is most commonly the result of production of a mutated pencillin-binding protein, PBP2a, which is able to carry out essential cell wall synthesis functions while maintaining a low-affinity for...

Perhaps you’ve punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could revolutionize healthcare in developing countries … and turn al... Read More
The study found that many models provided only cursory reference to the uncertainties of the information and data, or the parameters used
Research by scientists at the University of Liverpool has found that greater consideration of the limitations and uncertainties in infectious disease model... Read More
Viruses are the most abundant biological entities on the planet with approximately 1030 in the world’s oceans at any time. As such, they play a central role in global nutrient cycling. Despite their ecological importance, little is known about how viruses interact with their hosts due to the dif... Read More
Most of us are familiar with taking our daily probiotic supplement in the conventional way, either in capsule or powder form. It is however becoming increasingly apparent that people are discovering some weird and wonderful ways to use their probiotics, and here nutritional therapist Jo Saunders... Read More
A new biosensor quickly detects salmonella in food and can be easily customized to detect other types of bacteria—or even different strains for the same bacterium.
The process appears to easily outperform tests that are now standard in the food industry, according to researchers at Rice Unive... Read More
By tracing the evolutionary origin of a drug-like protein ring found in sunflowers, Australian and US scientists have discovered a diverse, 18-million-year-old group of buried proteins in daisy seeds.
Researchers at The University of Western Australia, working with academics from The Universi... Read More
From the discovery of the first Neanderthal skull in a Belgian cave in 1826, a bone of contention among Homo sapiens has been the extent of our relationship to Homo neanderthalis, who disappeared from the fossil record ~30,000 years ago. Like scrappy cousins we'd rather not claim, we've attempte... Read More
