This week's collection of papers discuss a variety of topics and keep us all intrigued where fitness, nutrition and sports science is headed. Check out the highlights below:
The Paleozoic diet: Why animals eat what they eat
In what likely is the first study on the evolution of dietary preferences across the animal kingdom, researchers report several unexpected discoveries, including that the first animal likely was a carnivore and that humans, along with other omnivores, belong to a rare breed.

Wearable sensors detect what's in your sweat
New easy-to-make sensors can provide real-time measurements of sweat rate and electrolytes and metabolites in perspiration
A team of scientists is developing wearable skin sensors that can detect what's in your sweat. In a new article, the team describes a sensor design that can be rapidly manufactured using a 'roll-to-roll' processing technique that essentially prints the sensors onto a sheet of plastic like words on a newspaper. The sensors can provide real-time measurements of sweat rate, and electrolytes and metabolites in sweat.

Football scores a health hat-trick for 55- to 70-year-old women with prediabetes
A new study shows that football is a surprisingly efficient type of physical training for female prediabetes patients, with impressive effects on cardiovascular health after 16 weeks of training for 55- to 70-year old women with no prior football experience.

Why brown fat is good for people's health
Study may help lead to drugs aimed at diabetes and obesity
Scientists have discovered how brown fat, also known as brown adipose tissue, may help protect against obesity and diabetes. Their study adds to our knowledge about the role of brown fat in human health and could lead to new medications for treating obesity and type 2 diabetes.

Certain metabolites linked to stem cell function in the intestine
Molecules called ketone bodies may improve stem cells' ability to regenerate new intestinal tissue
Researchers have found that high levels of ketone bodies, molecules produced by the breakdown of fat, help the intestine to maintain a functional stem cell pool, which are crucial for intestinal regeneration.

Junk food intake in children reduced by health education that addresses emotional issues
Teacher training followed by classroom education with information, activities, and emotional support improves lifestyles in teachers and students, according to new research. The study suggests that knowledge alone is insufficient to change behavior.

Remodeling unhealthful gut microbiomes to fight disease
You are what you eat -- right down to the microbiome living in your gut. Today, scientists will report the development of molecules that can change, or remodel, unhealthful gut microbiomes in mice into more healthful ones. The research could also someday be applied to other conditions related to diet.

Exercise is good for the aging brain
Researchers find a single bout of exercise boosts cognition, memory performance in some older people
Researchers have found that a single bout of exercise benefits some older people's brains. In experiments in which participants aged 60 to 80 exercised once and multiple times, the researchers found some individuals showed improved cognitive functions and working memory.
