When the eye jumps from one point to another, the image of our surroundings rapidly passes across the retina and triggers a wave of neuronal activity. In order not to be overwhelmed by the sensory impressions produced by our own movements, the brain suppresses processing of the stimuli as this happens.

Artificial intelligence (AI) is already being used in health care. AI can look for patterns in medical images to help diagnose disease. It can help predict who in a hospital ward might deteriorate. It can rapidly summarize medical research papers to help doctors stay up-to-date with the latest evidence.

A new study, published in Cell Reports, reports a novel mechanism behind dysregulated neuronal activity, a key pathology of amyotrophic lateral sclerosis (ALS). Researchers at King’s College London found that molecular, structural, and functional changes in the axon initial segment (AIS) drive abnormal neuronal excitability. This is the first study to pinpoint the role of AIS, a specialized region of motor neurons, in ALS pathology.

EXPELLED Matero MP MILES Sampa, the purported president of the Patriotic Front and his secretary general Morgan Ngona have been dragged to the Lusaka Magistrate Court for forgery and perjury.

Loss of neurons in in the retina due to trauma or disease leads to vision impairment or blindness, a process which is irreversible in humans. Interestingly, some animals like fish have the built-in ability to regenerate retinal neurons by turning another retinal cell type called “Muller glia” into neurons.

Skin-to-skin contact between parent and infant during the first hours after a very premature birth helps develop the child’s social skills. This is according to a new study published in JAMA Network Open by researchers from Karolinska Institutet and others. The study also shows that fathers may play a more important role than previous research has shown.

In a study with 22 pairs of identical twins, Stanford Medicine researchers and their colleagues have found that a vegan diet improves cardiovascular health in as little as eight weeks.

A new analysis of the brain activity of people with post-traumatic stress disorder (PTSD) is the first to reveal that traumatic memories are represented in the brain in an entirely different way than sad autobiographical memories.

To mark the occasion of World AIDS Day, Dr. Madeleine Durand and Andrés Finzi are working to reduce chronic inflammation and the risk of comorbidities in people living with HIV.

Climate change is making the fight against malaria even harder, with the campaign already struggling to make up ground lost during the COVID-19 pandemic, the World Health Organization warned Thursday.
