Why we need to take concussion and chronic traumatic encephalopathy more seriously
Concussion in sport continues to make headlines, whether it be class actions, young men flocking to the highly violent “RunIt” activity or debate about whether Australian rules football should remove the “bump” once and for all.
Foreign medical residents fill critical positions at US hospitals, but are running into visa issues
Some hospitals in the U.S. are without essential staff because international doctors who were set to start their medical training this week were delayed by the Trump administration’s travel and visa restrictions.
How dairy might disrupt your sleep and dreams
Ebenezer Scrooge tried to wave away the ghost of Jacob Marley by blaming the apparition on “an undigested bit of beef … a crumb of cheese.” Charles Dickens might have been writing fiction, but the idea that late-night dairy can warp dreams has now gained scientific support.
How AI is helping researchers to demystify gut bacteria
Gut bacteria are known to be a key factor in many health-related concerns. However, the number and variety of them is vast, as are the ways in which they interact with the body’s chemistry and each other.
Missing beneficial bacteria in infant guts linked to rising asthma and allergy cases
Nearly one in four infants lacks enough healthy gut bacteria essential for training their immune systems, putting them at greater risk of developing non-communicable diseases (NCDs) such as allergies, asthma, and eczema by age 2.
Cerebral cortex synapses transmit signals more reliably than those in rear brain regions
Researchers at Leipzig University’s Carl Ludwig Institute have discovered that in the cerebral cortex, synaptic signal transmission between brain cells functions very reliably even at low concentrations of calcium ions—unlike in the rear region of the brain.
Tracing dormant cancer cells: Chemotherapy spurs awakening, but senolytic drugs may prevent relapse
Breast cancer often relapses in distant organs even when complete regression of primary tumors is achieved after initial treatment. Dormant and persistent disseminated tumor cells (DTCs) have been observed in animals with non-metastatic disease, which cannot be targeted by systemic chemotherapy.
‘Chaotic and deeply frightening’: Once a global gold standard, US government health guidance is falling apart

Intelligent wound dressing controls inflammation
Chronic wounds are a major medical challenge, burdening health care systems with billions of dollars in costs every year. Pioneer Fellow Börte Emiroglu is developing a new product: a selective, sponge-like hydrogel that reduces inflammatory signals and actively promotes healing.
