Results of a study show convergent genetic adaptation under hypoxia (lack of oxygen) between populations living at high-altitude in the Himalayan region such as Tibetans and Sherpas, and the development of oxygen-starved cancer cells. The study was directed by Rodrigo Toledo, Head of the Vall d’Hebron Institute of Oncology’s (VHIO) Biomarkers and Clonal Dynamics Group and published in the journal Cancer Discovery.

Kenya’s government urged vigilance on Wednesday as it tackles a cholera outbreak that has killed at least five people, a health ministry official said.

There’s a mysterious connection between our skin and our guts, specifically when it comes to food allergies. For reasons scientists don’t fully understand, chronic skin conditions such as eczema are linked to food allergies; while the national prevalence of childhood food allergies is only around 8%, that prevalence rises to 30% in children with eczema. Researchers have discovered that in some cases, eczema can precede food allergies.

Plain radiographs (X-ray), computed tomography (CT) scans and magnetic resonance imaging (MRI) are commonly used in the evaluation of lower back pain. While MRI use has increased most over the past decades (more than 300% from 1994-2005), its use in low back pain (LBP) management can be associated with added costs and increased surgical interventions.

Eighty-five percent of diagnosed cases of lung cancer are non-small cell lung cancer (NSCLC). In this group, 5% of patients show molecular alterations in the ALK gene involved in cell multiplication. The use of inhibitors against this oncogene—one of the most effective strategies against this type of cancer—has benefited many patients. But, is it possible to know if the treatment will be effective in all those affected?

A simpler method of analyzing blood samples for Alzheimer’s disease has been tested in a large multicenter study led by Lund University in Sweden. “This is a major step in bringing simple blood tests for Alzheimer’s disease into the health care system globally,” say the researchers behind the study.

After nine years of painstaking work, an international team of researchers on Wednesday published a precise map of the vision centers of a mouse brain, revealing the exquisite structures and functional systems of mammalian perception.

From a tiny sample of tissue no larger than a grain of sand, scientists have come within reach of a goal once thought unattainable: building a complete functional wiring diagram of a portion of the brain.

New research led by a St. Michael’s Hospital clinician-scientist and published in the New England Journal of Medicine suggests that a therapy called Tolebrutinib could reduce disability progression in people with non-relapsing progressive multiple sclerosis (MS)—a subtype of MS that doesn’t respond well to current disease-modifying therapies.

Texas surpassed 500 measles cases Tuesday, just days after a third person died from a measles-related illness.
