A new study sheds light on how trade, and centrality in the global wheat trade network, affect food security. The study shows that many countries depend on trade to fulfill their food needs. Further, the global wheat trade is concentrated in a handful of countries whereby disruption in only a...
Novel, sensitive, and robust single-cell RNA sequencing technique outperforms competition
Single-cell RNA sequencing (scRNA-seq) is one of the most important methods to study biological function in cells, but it is limited by potential inaccuracies in the data it generates. Now, a research team has developed a new method called terminator-assisted solid-phase complementary DNA amplification and sequencing (TAS-Seq), which overcomes these...
Ancient microbes may help us find extraterrestrial life forms
Using light-capturing proteins in living microbes, scientists helped reconstruct what life was like for some of Earth's earliest organisms. These efforts could help us one day recognize signs of life on other planets.
Thin-film photovoltaic technology combines efficiency and versatility
Stacking solar cells increases their efficiency. Researchers have now produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent -- the highest value achieved thus far with this technology. Moreover, this combination of materials is light and versatile, making it possible to envision the use of these tandem...
Biofinder advances detection of extraterrestrial life
An innovative scientific instrument, the Compact Color Biofinder may change the game in the search for signs of extraterrestrial life.
NASA Data Supercharges Forecasting in Bangladesh
Bangladesh has a long history of deadly and costly storms.
3D printing of ‘organic electronics’
A research group has explored the potential production of micro-scale organic electronics for use in bioelectronics via multiphoton 3-D printers.
Changed gene expression after heart surgery extends cardiomyocyte regeneration
While lower vertebrates can repair their adult hearts after a heart attack, mammals -- including humans -- cannot. The ability to regenerate dead muscle tissue in mammalian hearts disappears just a few days after birth because the heart muscle cells, called cardiomyocytes, exit the cell cycle. In 2020, researchers reported...
With roommates, it’s all about chemistry, molecularly speaking
Researchers describe how the microbiomes of people and the homes they live in interact and change each other.
NASA, Partners Offer Global View of Environmental Changes
Continuing the collaboration that produced the COVID-19 Earth Observing Dashboard in 2020, NASA and its international partners in Europe and Japan have combined the collective scientific power of their Earth-observing satellite data in expanding the online resource to document a broad array of planet-wide changes in the environment and human...
