Tracking fossil fuel emissions with carbon-14

Researchers from NOAA and the University of Colorado have devised a breakthrough method for estimating national emissions of carbon dioxide from fossil fuels using ambient air samples and a well-known isotope of carbon that ...

The human factor limits hope of climate fixes

Engineering the climate can help lower temperatures and reduce climate change impacts. New research shows that when accounting for human behavior, climate engineering leads to significant economic and social risks. In a first-of-its-kind ...

A remote control for neurons

A team led by researchers at Carnegie Mellon University has created a new technology that enhances scientists' ability to communicate with neural cells using light. Tzahi Cohen-Karni, associate professor of biomedical engineering ...

Loss of land-based vertebrates is accelerating, study finds

In 2015, Stanford biologist Paul Ehrlich coauthored a study declaring the world's sixth mass extinction was underway. Five years later, Ehrlich and colleagues at other institutions have a grim update: the extinction rate ...

FloChiP, a new tool optimizing gene-regulation studies

In the cell, proteins often interact directly with DNA to regulate and influence the expression of genes. For this to happen, proteins need to travel into the cell's nucleus where the DNA is tightly twisted and packed as ...

A new view on how tissues flow in the embryo

As embryos develop, tissues flow and reorganize dramatically on timescales as brief as minutes. This reorganization includes epithelial tissues that cover outer surfaces and inner linings of organs and blood vessels. As the ...

Next frontier in bacterial engineering

From bacteria-made insulin that obviates the use of animal pancreases to a better understanding of infectious diseases and improved treatments, genetic engineering of bacteria has redefined modern medicine. Yet, serious limitations ...

Cellular players get their moment in the limelight

In order to understand our biology, researchers need to investigate not only what cells are doing, but also more specifically what is happening inside of cells at the level of organelles, the specialized structures that perform ...
