Interesting topics came up in the past two weeks in fitness, nutrition and sports science, some around the always actual topic of obesity, the role of vitamin K in older age, risks of drinking alcohol even in small amounts and one for the geeks about the smalles motor ever developed.
Here are the highlights
60 minutes of endurance training is enough to shift body clock in mice
New research shows that just one 60 minutes bout of exercise shifted the muscle clocks of mice by around an hour in either direction. If this research is replicated in humans, it makes a case for prescribing exercise for night-shift workers and for treating diseases like heart disease, both of which can result in disrupted clocks throughout the body.

The smallest motor in the world
A research team has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical motion and quantum tunneling -- and has revealed puzzling phenomena to researchers in the quantum realm.

Even 'low-risk' drinking can be harmful
It's not just heavy drinking that's a problem -- even consuming alcohol within weekly low-risk drinking guidelines can result in hospitalization and death, according to a new study.

Vegetarians tend to be slimmer and less extroverted than meat eaters, study finds
The less animal products someone consumes, the lower his body mass index on average and the less he tends to be extroverted. A connection with depressive moods as other studies had found could not be confirmed.

Multi-ethnic study suggests vitamin K may offer protective health benefits in older age
Older adults with low vitamin K had higher death risk over 13 years compared to those with adequate vitamin K levels
A new, multi-ethnic study found adults aged 54-76 with low circulating vitamin K levels were more likely to die within 13 years compared to those with adequate levels, suggesting vitamin K may offer protective health benefits as we age.

New approach to turning on the heat in energy-burning fat cells
Researchers have discovered a new set of signals that cells send and receive to prompt one type of fat cell to convert fat into heat. The signaling pathway, discovered in mice, has potential implications for activating this same type of thermogenic fat in humans.

'Fat burning' molecule has implications for treatment of obesity
Scientists have recently identified a small mitochondrial uncoupler, named BAM15, that decreases the body fat mass of mice without affecting food intake and muscle mass or increasing body temperature.
