The ESCAPE mission will study the evolution of exoplanet atmospheres
The habitable zone concept is useful for understanding which worlds might, possibly, maybe, be habitable. It highlights exoplanets at the right distances from their stars for liquid water to potentially exist on their surfaces. But that alone can't determine habitability.

Archaeology has evolved: Four eras of understanding Africa's past
What is the past? It may seem a simple question to answer, but it is more complex than we might think at first. As science, politics, technologies and ways of thinking change, so does our understanding of what went before.

Beauty by contrast: How hair color and background color influence skin appearance
Skin appearance plays an important role in the perception of age, health and attractiveness. Of course, skin appearance is affected by actual skin condition, but previous research has also found that it is affected by adjacent surfaces (e.g., eyebrows, eyes and lips).

Genetic neighborhoods distinguish harmful poultry bacteria from harmless strains
When it comes to identifying harmful bacteria, it helps to look at the company their genes keep. Researchers with the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas Division of Agriculture, used a machine-learning approach to study not just which genes a bacterium has, but also where those genes sit next to each other. That "genetic neighborhood" helped researchers distinguish disease-causing strains of Enterococcus cecorum, a poultry pathogen, from nonpathogenic strains.

AI-assisted grant proposals may win more often—while narrowing research ideas
A new study from Northwestern's Kellogg School of Management found that research proposals showing stronger signs of AI-assisted writing were four percentage points more likely to receive funding from the National Institutes of Health (NIH).

Real-time X-ray data analysis with DONUT accelerates materials science
What if scientists could get a taste of discovery as soon as their experiment finishes? Thanks to a new machine learning tool called DONUT, researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory are transforming how experiments are run at the Advanced Photon Source (APS), a DOE Office of Science user facility.
