Brain scans reveal how the human brain compensates when one hemisphere is removed

Researchers studying six adults who had one of their brain hemispheres removed during childhood to reduce epileptic seizures found that the remaining half of the brain formed unusually strong connections between different functional brain networks, which potentially help the body to function as if the brain were intact. The case study, which investigates brain function in these individuals with hemispherectomy, […]

Ischemia trial validates current practice standards

The Society for Cardiovascular Angiography & Interventions (SCAI) congratulates the investigators of the ISCHEMIA trial on their very important late-breaking research presented today at the American Heart Association 2019 Scientific Sessions. The results of the ISCHEMIA trial are consistent with earlier studies showing medical therapies are essential to keep people safe and help improve quality-of-life, with or without early intervention.

The ways astronauts prep for spaceflight could benefit cancer patients, say researchers

During spaceflight, astronauts experience similar physical stress as cancer patients undergoing treatments such as chemotherapy, immunotherapy, and targeted therapy. In a commentary published November 14 in the journal Cell, researchers suggest that by mimicking a NASA astronaut’s schedule of exercising before, during, and after a mission, cancer patients could reduce the long-term impact their treatments often have on their bodies.

Antibiotic-resistant infections could destroy our way of life, report says

Humanity’s defences against infection are wearing thinner by the day, and the microbes responsible are getting stronger. One in four infections is already resistant to antibiotics and other known forms of treatment, and 5,400 Canadians died last year from infections that until recently had been treatable. That’s according to a comprehensive peer-reviewed report presented by the Council of Canadian Academies […]

Late talkers twice as likely to have severe, frequent temper tantrums

Toddler speech delays and temper tantrums have long been assumed to go hand in hand, but no large-scale research had successfully backed up that assumption with data.  Until now.  A new, 2,000-participant study from Northwestern University found that toddlers with fewer spoken words have more frequent and severe temper tantrums than their peers with typical language skills.  It is the […]

The pathway to Parkinson’s takes a surprising twist

In neurodegenerative conditions like Parkinson’s disease, a specific group of neurons start to die one by one, causing movement problems and other symptoms. Scientists have long focused on finding out why these neurons die. Now it turns out, they might not even be dead. Researchers at The Rockefeller University found that affected neurons in Parkinson’s disease can shut down without […]

First case of dengue spread by sex confirmed in Spain

Spanish health authorities confirmed Friday a case of a man spreading dengue through sex, a world first for a virus which until recently was thought to be transmitted only by mosquitos. The case concerns a 41-year-old man from Madrid who contracted dengue after having sex with his male partner who picked up the virus from a mosquito bite during a […]
