A group of scientists, including several at Harvard, have dived deeper into the mammalian brain than ever before by categorizing and mapping at the molecular level all of its thousands of different cell types.

In a first-of-its-kind study published in Nature, researchers in the lab of Edward Chang, MD, at the University of California, San Francisco (UCSF) recorded activity from hundreds of individual neurons while participants listened to spoken sentences, giving us an unprecedented view into how the brain analyzes the sounds in words.

In a new study by researchers at the Yale School of Public Health, two “forever chemicals” spurred cancer cells in the lab to migrate to new positions, an indication that the chemicals could contribute to cancer metastasis in living organisms. The research is published in the journal Environmental Science & Technology.

A large international research collaboration, led by an academic from Royal Holloway, University of London, found that blood groups could help predict the risk of venous strokes associated with the Oxford-AstraZeneca COVID-19 vaccine.

Fibrosis is associated with various chronic and life-threatening conditions, including pulmonary fibrosis, liver cirrhosis, kidney disease, and cardiovascular diseases, among others. These conditions collectively contribute to a substantial portion of mortality in developed countries, making fibrotic diseases a critical health problem requiring attention, research, and innovative approaches for diagnosis and treatment.

Sensory cells and neurons in the ear communicate by secreting neurotransmitters in response to sound stimuli. Scientists of the University Medical Center Göttingen, the Cluster of Excellence Multiscale Bioimaging, and the Max Planck Institute for Multidisciplinary Sciences describe new details of this process that regulates the release of neurotransmitters and thus controls the transmission of sound stimuli. The results of this work were published in the Proceedings of the National Academy of Sciences.

A study led by David Berry and Alessandra Riva from the Center for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna has significantly advanced our understanding of prebiotics in nutrition and gut health.

Resistance to therapies is one of the obstacles to overcome in cancer treatments. Understanding the mechanisms of this resistance is essential to design strategies that favor tumor cell death. A study led by the Protein Kinases and Cancer group of the Vall d’Hebron Research Institute (VHIR), the Department of Biochemistry and Molecular Biology and the Institute of Neurosciences of the Universitat Autònoma de Barcelona (UAB) has deciphered a new mechanism to sensitize cancer cells to a specific therapy that so far has not been effective because of tumor resistance.

BATUKE Imenda, the UPND secretary general has strongly condemned the rogue behaviour of the Zambia Police for attacking Kasonde Mwenda, the Economic Freedom Fighters (EFF) president whose media briefing in Kitwe was disrupted on grounds that he did not get police permit for his interaction with the media.

A clinical trial reported in 2021 and conducted by a team of researchers from Washington University School of Medicine in St. Louis and the International Center for Diarrhoeal Disease Research in Dhaka, Bangladesh, showed that a newly designed therapeutic food aimed at repairing malnourished children’s underdeveloped gut microbiomes was superior to a widely used standard therapeutic food.
