Scientists unveil the functional landscape of essential genes
Researchers harness new pooled, image-based screening method to probe the functions of over 5,000 essential genes in human cells.
Nanosensors target enzymes to monitor and study cancer
By analyzing enzyme activity at the organism, tissue, and cellular scales, new sensors could provide new tools to clinicians and cancer researchers.
A “door” into the mitochondrial membrane
Study finds the protein MTCH2 is responsible for shuttling various other proteins into the membrane of mitochondria. The finding could have implications for cancer treatments and MTCH2-linked conditions.
With fractured genomes, Alzheimer’s neurons call for help
Study indicates ailing neurons may instigate an inflammatory response from the brain’s microglia immune cells.
Neurodegenerative disease can progress in newly identified patterns
A machine-learning method finds patterns of health decline in ALS, informing future clinical trial designs and mechanism discovery. The technique also extends to Alzheimer’s and Parkinson’s.
Biologists glean insight into repetitive protein sequences
A computational analysis reveals that many repetitive sequences are shared across proteins and are similar in species from bacteria to humans.
Using machine learning to identify undiagnosable cancers
A new model that maps developmental pathways to tumor cells may unlock the identity of cancers of unknown primary.
When cells’ tiny differences have far-reaching implications
Alex Shalek’s technologies for single-cell RNA profiling can help dissect the cellular bases of complex diseases around the globe.
New model helps identify mutations that drive cancer
The system rapidly scans the genome of cancer cells, could help researchers find targets for new drugs.
New CRISPR-based map ties every human gene to its function
Jonathan Weissman and collaborators used their single-cell sequencing tool Perturb-seq on every expressed gene in the human genome, linking each to its job in the cell.
Tracing a cancer’s family tree to its roots reveals how tumors grow
Family trees of lung cancer cells reveal how cancer evolves from its earliest stages to an aggressive form capable of spreading throughout the body.
Using plant biology to address climate change
A Climate Grand Challenges flagship project aims to reduce agriculture-driven emissions while making food crop plants heartier and more nutritious.
Structures considered key to gene expression are surprisingly fleeting
Study finds genome loops don’t last long in cells; theories of how loops control gene expression may need to be revised.
How molecular biology could reduce global food insecurity
Mary Gehring is using her background in plant epigenetics to grow climate-resilient crops.
Yukiko Yamashita, unraveler of stem cells’ secrets
