Synthetic “micro lungs” could take COVID-19 research to the next level

Scientists have developed stem-cell technology to mass-produce tissue cultures resembling our breathing organs. These tissues offer a powerful model in which to study how SARS-CoV-2 wreaks havoc in the lungs and to screen for new drugs.

The blood may hold clues to some of COVID-19’s most mysterious symptoms

COVID-19 causes a host of diverse complications, from lung inflammation to blood clots, heart failure, and brain fog. A team of scientists believes these attributes may have a single culprit—and that findings from research on Alzheimer’s disease might give them a leg up in finding it.
Gene expression atlas

New atlas reveals the journey of human cells throughout development

The largest map of gene expression in over 4 million human cells charts the dynamic path to forming different organs.

Awards and Honors

Rockefeller's Charles M. Rice honored with Nobel Prize for research that contributed to a cure for hepatitis C

Rice will receive the 2020 Nobel Prize in Physiology or Medicine for research that led to a cure for hepatitis C, a viral disease affecting 170 million people worldwide. His lab worked on the virus for three decades and became the first to produce a version of it that could be grown and studied i...

How mechanical forces nudge tumors toward malignancy

Researchers studying two forms of skin cancer identified a long-overlooked factor determining why some tumors are more likely to metastasize than others: the physical properties of the tissue in which the cancer originates. The findings might set the stage for new ways to monitor and treat the di...

Transparent fish reveal the subtle, cellular dance in which sensory organs take shape

How do primitive cells “know” where to go during development? Scientists studying the fish equivalent of inner-ear hair cells have shown that biochemical and mechanical cues work together to orchestrate a highly complex arrangement.
BRCA2 mutation

Unique mutation reveals a new role for well-known DNA-repair gene

The discovery of a rare mutation in BRCA2, commonly known as the breast cancer gene, has shed new light on how cells safeguard their genetic material.

How skin cells embark on a swift yet elaborate death

Scientists have identified the mechanism that allows skin cells to sense changes in their environment, and very quickly respond to reinforce the skin's outermost layer. The findings provide insight into how errors in this process might lead to skin conditions like psoriasis.

Researchers discover a new mechanism in childhood kidney cancer

A problem in reader proteins that identify which gene is up for expression may cause normal cells to turn malignant during development.

Neurodegenerative diseases may be caused by molecular transportation failures inside neurons

Protein clumps are routinely found in the brains of patients with neurodegenerative diseases. Now researchers find a link between this buildup and the intracellular movement of proteasomes, molecular machines tasked with degrading protein waste inside cells.
