Our immune system copes with a multitude of threats using a mix-and-match system to create millions of different antibodies.
Sulfur signals in the Antarctic snow have revealed the importance of overlooked atmospheric chemistry for understanding climate, past and future.
Embryonic stem cells can develop into a multitude of cells types. Researchers would like to understand how to channel that development into the specific types of mature cells that make up the organs and other structures of living organisms.
An elusive state of matter called superconductivity could be realized in stacks of sheetlike crystals just a few atoms thick, a trio of physicists has determined.
Taking a moment to pause and relax can help if you find yourself in a tight spot. This strategy can work for molecules as well as people, it turns out. Researchers at UC San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax.
It's no surprise that official tallies of the inhabitants of a city miss many residents. Not everyone wishes to be counted, particularly not those who lack legal permission to be there, and censuses are infrequent, if they happen at all.
Professor Kiran Kedlaya has won a Guggenheim Fellowship, to further his work in number theory, one of the most classical branches of mathematics.
It's the faintest light, yet it carries information from the beginning of time. A telescope trained on the Antarctic sky has picked up swirling patterns of light believed to be the imprint of the violent expansion of the universe a trillionth of a trillionth of a trillionth of a second after it burst…
Cosmologists have detected curling patterns in the faint glow of the universe's oldest light that appear to be traces left by cosmic inflation, an exponential expansion of the universe thought to have occurred fractions of a second after the Big Bang, they announced today.
Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be “tuned” to particular frequencies and amplitudes by varying the number of layers of crystal,…
