Deadly superbugs may be spreading, evolving quietly among the healthy
20th January 2017 | Animal Life, Humans

For years, researchers have been tracking a particularly nasty family of superbugs called CREs, or carbapenem-resistant Enterobacteriaceae, which can thwart antibiotics in our last lines of defense. Researchers have watched in horror as clinical isolates gathered new molecular weaponry, spread through medical facilities across the globe, and started causing more and more life-threatening infections.

UV light can aid hospitals’ fight to wipe out drug-resistant superbugs
20th January 2017 | | Animal Life, Humans, Tech

A new tool — a type of ultraviolet light called UVC — could aid hospitals in the ongoing battle to keep drug-resistant bacteria from lingering in patient rooms and causing new infections.

Noise pollution from fracking may harm human health
20th January 2017 | Earth, Humans

Fracking creates noise at levels high enough to harm the health of people living nearby, according to the first peer-reviewed study to analyze the potential public health impacts of ambient noise related to fracking.

Caffeine may counter age-related inflammation
20th January 2017 | Humans

A chronic inflammatory process that occurs in some, but not all, older people may trigger cardiovascular problems, a new Stanford study shows. Part of the solution might be found in a cup of coffee.

Science Says This Weird Virus Could Make You Fat
20th January 2017 | | Humans

It’s January, the month of new diets and gym memberships. In the spirit of starting off a brand new year, there’s no reason not to eat healthier and move around more. But if your aim is just to lose pounds, you might be on the wrong track. In her new book, The Secret Life of Fat, biochemist Sylvia Tara reveals what many dieters have suspected for a long time: There’s more to losing weight than just eating less and exercise.

High-sugar diet programs a short lifespan in flies
20th January 2017 | | Animal Life, Humans

Flies with a history of eating a high sugar diet live shorter lives, even after their diet improves. This is because the unhealthy diet drives long-term reprogramming of gene expression, according to a team of researchers.

Have Scientists Found a Way to Actually Reduce the Effects of Aging?
19th January 2017 | | Humans, Tech

There are some 200 different types of cells in the body, but they can all be traced back to stem cells. Before they differentiated into heart, liver, blood, immune cells, and more, they were called pluripotent, meaning they could become anything.

Yoga is the key to relieving long-term back pain, new study suggests
19th January 2017 | | Humans

With its catalogue of headstands and one-legged contortions, it might be thought yoga was best left only to those in peak physical condition.

Acupuncture may alleviate babies’ excessive crying (infantile colic)
19th January 2017 | | Humans

Acupuncture may be an effective treatment option for babies with infantile colic — those who cry for more than three hours a day on three or more days of the week — reveals research.

Revenge really is sweet: study shows the mood-enhancing effect of retaliation
19th January 2017 | Humans

When we feel ostracised, we’re more likely to behave aggressively. Previous research suggests that vengeance on those who we think have wronged us can be driven by a sense of justice, and may activate neural reward centres. But being ostracised can also lead to generalised aggression, even lashing out at unrelated people, so there seems to be more going on.

Weekend workouts can benefit health as much as a week of exercise, say researchers
19th January 2017 | | Humans

People who cram all their exercise into one or two sessions at the weekend benefit nearly as much as those who work out more frequently, researchers say.

A study of more than 60,000 adults in England and Scotland found that “weekend warriors” lowered their risk of death by a similar margin to those who spread the same amount of exercise over the whole week.

Eat hot peppers for a longer life? Study
18th January 2017 | | Humans

Like spicy food? If so, you might live longer, say researchers at the Larner College of Medicine at the University of Vermont, who found that consumption of hot red chili peppers is associated with a 13 percent reduction in total mortality — primarily in deaths due to heart disease or stroke — in a large prospective study.

Humanity May Have Reached its Maximum Lifespan
18th January 2017 | Humans

Global life expectancy has now reached an average that’s regularly in the 80s in Japan and Canada —and in the United States it’s reached a high of 78 years.

Have we reached the end of the line when it comes to living longer and healthier lives? Is there a point at which diminishing returns just mean any gains in lifespan are bound to be insignificant and temporary?

Scientists Could Identify a Person’s Age by Looking at These Cells in Their Brain
18th January 2017 | Humans, Tech

By examining the brains of 480 people that died between the ages of 16 and 106, researchers have learned that glial cells experience bigger changes than neurons during aging.

This information could lead to better treatment options for neurological disorders, such as dementia and Alzheimer’s, or even ways to combat aging altogether.

A Nevada woman dies of a superbug resistant to every available antibiotic in the US
16th January 2017 | | Humans

If it sometimes seems like the idea of antibiotic resistance, though unsettling, is more theoretical than real, please read on.

Public health officials from Nevada are reporting on a case of a woman who died in Reno in September from an incurable infection. Testing showed the superbug that had spread throughout her system could fend off 26 different antibiotics.

‘Puppy talk’ – why do we use it and do dogs respond?
16th January 2017 | | Animal Life, Humans

Scientists have decoded “dog-directed speech” for the first time, and they say puppies respond to it.

Puppies reacted positively and wanted to play when researchers in France played them a tape of phrases like, “Who’s a good boy?”

Sorry, Steak Lovers: Red Meat Linked to Gut Condition
15th January 2017 | | Animal Life, Humans

Men who regularly eat red meat have a higher risk of developing an inflammatory bowel condition called diverticulitis than men who don’t have much red meat in their diet, a new study finds.
