by Piter Kehoma Boll One of the most iconic representations of praying mantids is that of a female eating the male after (or during) sex, an unpleasant scenario that starts with a beheading before the poor male even finishes his … Continue reading →... Read more »

I'd like to briefly draw your attention to the results - systematic review and meta-analysis results - published by Joseph Firth and colleagues  observing that "certain vitamin and mineral supplements may reduce psychiatric symptoms in some people with schizophrenia" and specifically that certain B vitamins might be something to consider.Such results come from a research team who are making significant waves in the field of meta-analyses and systematic reviews for all manner of different [imp........

Previous studies show that BHD syndrome causes spontaneous pneumothorax (SP) in 24-38% of patients, with a recurrence rate of up to 75% (Toro et al., 2007; Toro et al., 2008; Houweling et al., 2011). A common preventative strategy used following an initial SP in patients with BHD is pleurodesis, however, its efficacy in preventing recurrent episodes is not well known. Due to the pressure changes during air travel, cystic air spaces expand and compress in the thorax possibly leading to cyst ruptu........ Read more »

"Desk-bound workers should ‘walk EIGHT miles a day’ to slash risk of heart attacks or stroke" went one headline talking about the findings reported by William Tigbe and colleagues . Drawing on data from over 110 postal workers - "(55 office-workers, 5 women, and 56 walking/delivery-workers, 10 women)" - who wore "activPAL physical activity monitors for seven days", researchers observed some potentially important trends.Alongside wearing their activity monitors, participants were also asse........

In a curious case report, Indian psychiatrists Lekhansh Shukla and colleagues describe a young man who said he regularly got high by being bitten by a snake.
The 21-year old patient sought treatment for his heavy drug abuse, which included heroin and marijuna. He also reported a less conventional habit: he visited a local snake charmer, where he was bitten on the lips by a "cobra" in order to get high:
He reported that his peers and the snake charmer informed him that he would have drows... Read more »

In a recent study, researchers provide a new theory for the reason we walk the Earth
A new provocative study suggests it was the power of the eyes and not the limbs that first led our ancient aquatic ancestors to make the momentous leap from water to land. According to it, crocodile-like animals first saw easy meals on land and consequently evolved limbs that enabled them to get there, ... Read more »

Do online pet obituaries reveal how we truly feel about our pets?Guest post by Jane Gething-Lewis (Hartpury College).“You were such a selfless and giving boy. Dad loves you with all his heart.”A heartfelt online tribute to a dearly departed loved one – but this loved one had four legs, a tail and was called Cosmo. Over the top? Not necessarily. Research suggests that many people feel the loss of a beloved pet as keenly as the loss of a child.The bond people have with each other has long be........ Read more »

Radiotherapy is a highly efficient treatment for many cancers including breast cancer. Intraoperative radiotherapy (IORT), a relatively new type of radiation therapy, has proven successful as a curative treatment for early cancer stages. However, in spite of great improvements in dose delivery and imaging technology, unwanted exposure of healthy tissue to radiation cannot be fully avoided. The resulting late-onset toxicity due to the exposure of health tissue currently limits the usefulness of r........ Read more »

Older drivers are over-represented in motor-vehicle driving accidents.The lowest rate of fatal vehicle crashes per 100 million miles driven is found in drivers between the ages of 30-69 years of age.Fatal vehicle driving rates per miles driven is 4 to 5 times higher in drivers over 80 years of age.
