Bacteria

Researchers have found that common gut bacteria prevent sensitization to peanut allergens ...

As someone who almost shuffled off this mortal coil after downing a satay, I'm always hopeful when potential breakthroughs for the treatment of food allergies arise. The latest cause for hope, which could one day let food allergy sufferers order in restaurants without worrying about potentially life-threatening ingredients hidden within, comes from scientists at the University of Chicago Medicine, who have found that a common gut bacteria protects against food allergies in mice.  Read More

A new antibacterial gel has been shown to penetrate and kill off certain kinds of superbug...

Drug-resistant bacteria, or so-called superbugs, pose a very real threat to public health. The over prescription and consumption of antibiotics has contributed to a resilient new breed of germs that could see minor infections once again evolve into life-threatening conditions. The latest development in the fight against this threat comes from scientists at Queens University in Belfast, who have produced an antibacterial gel capable of breaking through a protective casing and killing off certain types of drug-resistant bacteria.  Read More

A modified version of C. noyvi bacteria has been found to produce an anti-tumor response t...

Bacteria found in soil called Clostridium novyi (C. novyi) is known to cause tissue-damaging infections. But researchers from John Hopkins Kimmel Cancer Center have developed a modified version that triggers an anti-tumor response in rats, dogs and humans. The breakthrough could complement existing methods to provide better targeted treatment of cancerous growths.  Read More

Tokia University researchers have developed a nanosheet material that clings to irregular ...

Even with advances in gels and dressings, burns remain a difficult injury to treat. This applies particularly to parts of the body where the skin bends around bones and joints, creating surfaces unfavorable to most types of bandaging. But researchers from Japan's Tokai University have developed a new ultra-thin material that clings to those trickier locations, serving to ward off infectious bacteria.  Read More

Researchers have modified a strain of E. coli to produce a lipid compound called NAPE in t...

Researchers at Vanderbilt University in Nashville, Tennessee have raised hopes for the possibility of developing of a probiotic to treat obesity and other chronic diseases. The team inhibited weight gain, insulin resistance and various other negative health effects of a high-fat diet in mice by modifying bacteria to produce a therapeutic compound in the gut.  Read More

Jeremy Nussbaumer with the DrinkPure filter

It's no secret that hundreds of millions of people around the world have little or no access to drinkable water. While a number of projects are aimed at getting filtration systems to those people, many of those systems require electricity, contain costly materials such as silver, or treat the water at a slow rate. The low-cost DrinkPure filter, by contrast, is simply screwed onto the top of an existing bottle, and can purify approximately one liter (34 fl oz) of water per minute.  Read More

Waste like this should meet all of a UK grocery store's electrical needs (Photo: Shutterst...

It's an unfortunate fact that every day around the world, supermarkets throw out tons of food that has spoiled before it could be purchased. While it would be best if that spoilage could be avoided in the first place, British grocery chain Sainsbury's is taking what might be the next-best approach – it's about to start using that unsellable food to power one of its stores.  Read More

A research team from McMaster University, the University of British Columbia and Cardiff University has discovered a fungus in the soil of the Canadian province of Nova Scotia that may offer hope in an increasingly fraught battle against drug-resistant bacteria.  Read More

Researchers have discovered a way to lower the defenses of antibiotic-resistant bacteria, ...

The discovery of antibiotics is one of the most important breakthroughs of the 20th century. But their effectiveness and low cost has led to their overuse, resulting in the worrying rise of antibiotic-resistant bacteria, or so-called superbugs. Researchers at the University of East Anglia (UAE) in England have now uncovered an Achille's heel in the bacterial cell defenses that could mean that bacteria wouldn't develop drug-resistance in the first place.  Read More

NASA astronaut Rick Mastracchio prepares to test the ultraviolet light decontamination har...

The International Space Station (ISS) is perhaps the most artificial environment that human beings have ever taken up residence in. It’s not the sort of place where you’d want a lab accident, because you can’t run out the door and wait in the carpark for the air to clear, so NASA uses gloveboxes to keep the crew and equipment separate from dangerous contaminants. To increase this level of safety and expand the number experiments the station can carry out, the space agency is fitting one of the larger gloveboxes with an Ultraviolet Germicidal Irradiation (UVGI) system to to prevent potentially dangerous microorganisms from escaping.  Read More
