One in three young athletes who undergo ACL surgery experiences re-injury, according to research presented today at the American Orthopaedic Society for Sports Medicine’s Specialty Day. The study examined the long term success of surgery for patients aged 18 years and younger. —> Read More
How best to treat and recover from complicated hip injuries is a growing field in orthopaedic medicine. While diagnostic hip injections are commonly performed for patients with labral tear to confirm the pain etiology, research presented today at the American Orthopaedic Society for Sports Medicine’s Specialty Day suggests that pain relief from this diagnostic injection may not predict better outcomes following arthroscopic hip surgery. —> Read More

An individual’s meniscus (cushion in the knee) is one of the most important ligaments in the leg providing stability, load bearing and preservation of the knee joint. It is also one of the most easily injured areas and difficult to fully heal. Researchers presenting their study at today’s Specialty Day meeting of the American Orthopaedic Society for Sports Medicine utilized MRI data to determine the potential for biologic healing following a meniscus tear. —> Read More
Early surgery may not be the best treatment option for patients with Type V AC joint injuries, according to new research from Tripler Army Medical Center. The study, presented today at the American Orthopaedic Society for Sports Medicine’s Specialty Day, showed military personnel returned to duty faster when surgery was not performed. —> Read More
A day on Saturn lasts 10 hours 32 minutes 45 seconds (+/- 46 seconds), says a group of astronomers led by Dr Ravit Helled of Tel Aviv University, Israel. To measure the rotation period of Saturn – the sixth planet from the Sun, Dr Helled and his colleagues from the Weizmann Institute of Science in [...] —> Read More

We know that humans are wired to fall in love, but are we also built to break up?
Love is what evolutionary psychologists call a human universal — a fundamental human experience that appears across all cultures. According to a new study, the experience of falling out of love and moving on to a new partner may be just as universal.
A recent review of evolutionary psychology literature, conducted by researchers at Saint Louis University, Florida State University and the University of Cincinnati, suggests that humans are built to experience the pain of a breakup and then move on to a new partner, and that our brains actually facilitate the severing of romantic ties.
The researchers explain that the ability to endure heartbreak and ultimately enter a new relationship may have offered an evolutionary advantage.
“In our evolutionary past, selection pressures may have been such that individuals who could successfully jettison a mate and find a new one, when the situation called for it, would have been better able to solve the evolutionary imperative of reproduction — in other words, they sent more of their genes on to the next generation,” Dr. Brian Boutwell, an epidemiologist at Saint Louis University and the study’s lead author, told The Huffington Post.
Boutwell and his colleagues looked at the process of falling out of love and ending a relationship (what they call “primary mate ejection”) and the process of entering a new relationship (“secondary mate ejection”). Drawing on research showing that the brain circuitry involved in romantic love is also implicated in addictive behaviors, they hypothesized that falling out of love and moving on is a process akin to overcoming a drug addiction. And of course, those who are able to do so successfully have better survival and reproductive odds.

Southeastern Indiana is battling an HIV outbreak. The new cases are mostly linked to injection drug use and have reignited a debate over needle exchanges, which are currently illegal in the state.
Researchers have finally determined the length of a day on the ringed planet (gas shrouds any landmarks, so it was tough). Precision matters: A faster spin influences the speed of surface winds.
