In high school and college, your coach told you to avoid alcohol. And for good reason; alcohol saps muscle strength and it's lingering lethargic effects aren't welcome either.

The lack of muscle strength really becomes evident when studying long-time alcoholics but it is also evidence in patients with mitochondrial disease.  A new study on mitochondria that are unable to self-repair may mean a new way to diagnose mitochondrial disease, and a new drug target. 


A systematic review in the Journal of Nutrition has associated iron supplements with improved exercise performance of women in child-bearing years.

Lead researcher, Dr Sant-Rayn Pasricha from the University of Melbourne School of Population and Global Health and colleagues concluded that iron supplementation improved women’s exercise performance, in terms of both the highest level they could achieve at 100% exertion (maximal capacity) and their exercise efficiency at a submaximal exertion. Women who were given iron were able to perform a given exercise using a lower heart rate and at a higher efficiency.


NJIT Associate Professor of Mathematical Sciences Bruce Bukiet has released his annual Major League Baseball projections and he doesn't say see good things for the Pittsburgh Pirates - the official baseball team of Science 2.0 - but at least his favorite team, the Mets, are going to stink too.

Well, in the world of Bayes projections anyway. They still have to play the games. 

Bukiet's model, published in Operations Research, can be used to project the number of games a team should be expected to win, the optimal batting order for a set of 9 batters, and how trading players will likely influence a team's number of wins.


Golfers would rather they not hit a rock with their titanium alloy golf clubs anyway, but now they have a more compelling reason than the cost of buying a new one; they can create sparks that are more than 3,000 degrees Fahrenheit which can ignite dry foliage.

So if you really want to golf during the drought, you now have one more thing to overthink while playing. 

In a Fire and Materials, the authors say Orange County, California, fire investigators asked U.C. Irvine to determine whether such clubs could have caused blazes at Shady Canyon Golf Course in Irvine and Arroyo Trabuco Golf Club in Mission Viejo a few years ago.


It used to be that you might see someone walking with some difficulty and they might say 'old football injury'. 

That happens less and less, as long as they didn't have a long career as an offensive lineman. The anterior cruciate ligament is one of four that connect the thigh bone to the shin bone. Over-stretching or tearing of this ACL, partially or completely, used to be quite common - and career-ending.


Ulnar collateral ligament (UCLR) reconstruction, a common injury for pitchers in Major League Baseball, is often called "Tommy John Surgery" after the New York Yankees pitcher who made it famous, In 1974, Dr. Frank Jobe made medical history when he replaced the pitcher's torn medial collateral ligament with a tendon from John's forearm and he went on to pitch for 14 more years and added 164 more victories - after an injury that had been career-ending in the past.

Results out today show that pitchers win more games following Tommy John Surgery but another paper disagrees. The scholars at Henry Ford Hospital say the performance decline is notabled and that they the largest cohort of professional pitchers to date to examine the issue.


Ulnar collateral ligament (UCLR) reconstruction, commonly called "Tommy John Surgery" after the New York Yankees pitcher who made it famous, is a procedure performed on Major League Baseball pitchers after they get a damaged or torn ulnar collateral ligament, a common elbow injury.  In 1974, Dr. Frank Jobe made medical history when he replaced the pitcher's torn medial collateral ligament with a tendon from John's forearm.

John then pitched for 14 more years and added 164 more victories - after an injury that had been career-ending in the past.


When women enter menopause, estrogen levels drop and that is linked to increased risk of cardiovascular disease, but research from  University of Copenhagen’s Centre for Team Sport and Health finds that interval-based team sport can make up for this estrogen loss.

Estrogen, the primary female sex hormone, is an important guardian of the female vascular system. Thus, s oestrogen levels fall during menopause, the risks of increased blood pressure and development of cardiovascular disease increases.  Team sports improve the condition of women, reduces blood pressure and thus protects the cardiovascular system.  


In soccer, a team is most vulnerable to being scored on right after they score. Pundits and psychologists attribute that to overconfidence. Yet in the 2014 Super Bowl, the Seattle Seahawks dominated early and the Denver Broncos looked increasingly disorganized. Pundits and psychologists attribute that to momentum.

Momentum or overconfidence are often applied in hindsight to individual games but what about during winning streaks? Is what analysts term momentum a kind of competitive inertia, where a team in a state of winning tends to keep winning? 

No, say economists writing in Economics Letters, after examining varsity college hockey teams winning and losing records. Momentum advantages don't exist.


Older football veterans contend that modern equipment, and its ability to protect players from injury, ironically lead to more of it. Rugby players agree. 

They may be right. A new study finds that modern football helmets do little to protect against hits to the side of the head and the rotational force that is often a dangerous source of brain injury and encephalopathy.
