The early stages of embryonic development contain many of life’s mysteries. Unlocking these mysteries can help us better understand early development and birth defects, and help develop new regenerative medicine treatments.

Researchers based at the Australian Regenerative Medicine Institute (ARMI) at Monash University have characterised a critical time in mammalian embryonic development using powerful and innovative imaging techniques, with their work published in Nature Communications.

Every year, hundreds of thousands of people in West Africa become infected with Lassa virus, which can cause Lassa fever and lead to severe illness, long-term side effects or death. There are currently no widely approved treatments or vaccines for the disease. Now, scientists at Scripps Research have determined the structure of the critical protein complex that lets Lassa virus infect human cells.

New research from Oregon Health & Science University is helping explain why at least five people have become HIV-free after receiving a stem cell transplant. The study’s insights may bring scientists closer to developing what they hope will become a widespread cure for the virus that causes AIDS, which has infected about 38 million people worldwide.

Antiretroviral cocktails can make human immunodeficiency virus, or HIV, undetectable and untransmittable, but both the virus and its treatment can also accelerate aging of bone and muscle.

Now Medical College of Georgia scientists are looking at drugs already being studied in clinical trials for cancer to help put the brakes on these classic indicators of aging that can lead to falls, fractures and early frailty.

A major challenge in human genetics is understanding which parts of the genome drive specific traits or contribute to disease risk. This challenge is even greater for genetic variants found in the 98% of the genome that does not encode proteins.

A new approach developed by researchers at New York University and the New York Genome Center combines genetic association studies, gene editing, and single-cell sequencing to address these challenges and discover causal variants and genetic mechanisms for blood cell traits.

Bacteria naturally adapt to various environmental stimuli and as they mutate, these changes can make them resistant to drugs that would kill or slow their growth.

In a recent article published in PLoS Genetics, UCF College of Medicine microbiologist Salvador Almagro-Moreno uncovers the evolutionary origins of antimicrobial resistance (AMR) in bacteria. His studies on the bacterium that causes cholera, Vibrio cholerae, provide insight into deciphering what conditions must occur for infectious agents to become resistant.

When you need a bit of motivation, it often has to come from within. New research suggests cancer-fighting immune cells have found a way to do just that.

Scientists at University of California San Diego have discovered a property of T cells that could inspire new anti-tumor therapeutics. Through a previously undescribed form of cell auto-signaling, T cells were shown to activate themselves in peripheral tissues, fueling their ability to attack tumors.

Sweat is more than just a sign of a good workout. It holds vital information about our health, providing clues to dehydration, fatigue, blood sugar levels and even serious conditions such as cystic fibrosis, diabetes and heart failure. Researchers at the University of Hawaiʻi at Mānoa College of Engineering have taken a giant leap forward in sweat analysis with an innovative 3D-printed wearable sweat sensor called the “sweatainer.”
