How Short Bursts of Activity Can Get You Fit

If you think you don't have time to exercise, there's good news: Short bouts of activity — as brief as a few minutes each — may still have health benefits, as long as they add up to 30 minutes a day total, recent research suggests. Traditionally, experts have recommended that people exercise for at least 10 minutes at a time, at a moderate pace. Since people have trouble remembering very short activities, it was hard to study whether smaller amounts of exercise could improve your health, said Brad Cardinal, a kinesiology professor at Oregon State University.

Income Inequality: Is There a Grooming Gap?

The researchers found that overall, men and women who were considered more attractive earned more money than their less-attractive counterparts, according to the study, published online last month in the journal Research in Social Stratification and Mobility. For women, those who were well-groomed women actually had higher incomes than poorly groomed women, regardless of their "natural" level of attractiveness, the researchers found.

'Poop Transplant' Changes Play Out Over Several Months, Study Finds

Patients who undergo a "poop transplant" to treat severe diarrhea often see their symptoms get better within days, but their gut bacteria continue to undergo dramatic changes for at least three months afterward, a new study finds. Researchers analyzed the gut bacteria of eight patients who had Clostridium difficile, a difficult-to-treat bacterial infection that can be life-threatening. After several earlier treatments for their infection didn't work, all of the patients underwent a procedure called fecal microbiota transplantation (FMT), in which fecal matter from a healthy donor is delivered into a patient's colon, in order to restore a better balance of bacteria within the gut.

Why Processed Foods May Promote Gut Inflammation

Certain food additives may interfere with your gut bacteria, causing changes that boost inflammation in the intestines and potentially promote the development of some chronic diseases, a new study suggests. In the study, researchers looked at ingredients called emulsifiers, which are added to many processed foods, including ice cream and peanut butter, to improve those foods' texture and extend their shelf life. The scientists added two emulsifiers called carboxymethylcellulose (CMC) and polysorbate-80 (P80), to a simulation of normal gut contents.

5,000-Year-Old Chinese Beer Recipe Had Secret Ingredient

Barley might have been the "secret ingredient" in a 5,000-year-old beer recipe that has been reconstructed from residues on prehistoric pots from China, according to new archaeological research. Scientists conducted tests on ancient pottery jars and funnels found at the Mijiaya archaeological site in China's Shaanxi province.

Ugliest to Most Rock 'n' Roll: Top Newfound Species Named

With such a large number of species discovered each year, the SUNY College of Environmental Science and Forestry (ESF) has put together a list of the "Top 10 New Species," celebrating species named in the previous year, since 2008. In the absence of a global species registry, the annual list is a reflection the Earth’s diverse species population, said Quentin Wheeler, ESF president and founder of the school's International Institute for Species Exploration (IISE). "We want to bring attention to the biodiversity crisis," Wheeler told Live Science.

Insoles That Buzz Your Feet Could Improve Balance

Insoles that electrically stimulate the feet with random vibrations that are too gentle to feel can affect a person's stride, and may boost stability, offering a potential new way to decrease the risk of falls and injury from balance loss, a new study finds. Study participants undergoing strenuous activity while wearing such insoles adjusted their strides in a way that typically improves balance, the research found. The insoles work using a process called "stochastic resonance" (SR), a method for amplifying a weak signal by adding "white noise" across a spectrum of frequencies.

Shark Bay Bloodbath: 70 Sharks Devour a Humpback Whale

On May 20, tourists on an Australian cruise witnessed an incredible but gruesome sight: approximately 70 tiger sharks tearing apart the carcass of a humpback whale in Shark Bay. The tour company, Eco Abrolhos, encountered the bloody scene during the fourth day of a 14-day cruise, as the group traveled near Steep Point, Dirk Hartog Island, according to a post on the company's Facebook page.
