Gut bacteria discovery could lead to probiotic therapy for food allergies

By - August 31, 2014 1 Picture
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.

Antibacterial gel uses natural proteins to kill off hospital superbugs

By - August 19, 2014 1 Picture
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.

Nanosheet burn dressing clings to uneven skin

By - August 12, 2014 1 Picture
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

DrinkPure water filter shows promise for worldwide use

By - July 25, 2014 3 Pictures
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

Sainsbury’s supermarket to be powered entirely by its own food waste

By - July 23, 2014 1 Picture
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.

Achilles' heel to lower defenses of antibiotic-resistant bacteria found

By - June 20, 2014 1 Picture
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.

Decontamination system turns space station into life science laboratory

By - June 16, 2014 2 Pictures
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.
