A lipid switch that blocks anthrax from entering cells

Every cell carefully builds and positions thousands of proteins that allow it to sense and respond to its surroundings. Even small changes to these proteins often determine whether they work properly or are destroyed before they ever reach the cell surface. One such protein is

New report shows nation's population growth is slowing

An estimated 370 million people will live in the United States in 2050, with more than 40% living in the South, according to national and 50-state population projections recently released by the University of Virginia's Weldon Cooper Center for Public Service.

A way to read quantum bits faster and with less hardware

Quantum computers process information in a fundamentally different way from conventional computers, using quantum bits, or qubits, that can exist in multiple states at once. This could allow them to tackle problems beyond the reach of today's machines, from simulating new

Tabby's star may be orbited by a planetary-mass companion

By analyzing data from NASA's Transiting Exoplanet Survey Satellite (TESS) and conducting new radial velocity measurements, U.K. and French astronomers have found evidence that the mysterious Tabby's star may be orbited by an object about nine times more massive than Jupiter.

Martian space suits will need to be 40% lighter

Long before a human ever sets foot on the Red Planet, we already know how harsh the environment is. Once a human finally does, the only things protecting them from that environment will be the infrastructure we've built there and the spacesuit that keeps them in a protective

JWST could spot volcanic 'exo-Ios' around super-Jupiters

Jupiter's moon Io is the most volcanically active planetary body in the solar system, boasting hundreds of active volcanoes that spew molten lava into space. This activity results from a process called tidal heating, in which Jupiter's massive gravity constantly stretches and

Misfolded insulin may be quietly driving diabetes

Researchers found that insulin-producing cells depend on a team of helper proteins to keep insulin production on track. When one key partner was missing, damaged proteins built up and the cells made less insulin. Strengthening this system could offer a new way to protect the

NASA science soars during August total solar eclipse

Each time the moon covers the sun during a total solar eclipse—darkening daytime skies and briefly revealing the sun's ethereal outer atmosphere, the corona—it presents new opportunities to better understand our star and its influence on Earth.

Twisted laser light can tell mirror-image molecules apart

Scientists have created twisted laser beams that interact differently with right-handed and left-handed molecules, revealing their identity through the fragments they produce. The approach could provide a faster, simpler, and more sensitive way to analyze important molecules

Q&A: What influences teens' career expectations?

Adolescents in both the United States and the United Kingdom have become increasingly ambitious about their future careers over the past two decades, according to a new study by researchers at Penn State. The team also found that family socioeconomic background plays a
