Physicists discover “astonishing” property of light that defies expectations
Scientists have uncovered a surprising hidden ability of light that allows it to develop spinning, twisting behavior as it travels through empty space, without special lenses, mirrors, or materials. Researchers discovered that light’s internal geometry can naturally produce left-

Judging strangers' preferences may actually be easier when they're less like our own
Researchers already know that humans have a tendency to use egocentric anchoring—a cognitive bias in which people use their own preferences, beliefs and perspectives as a mental starting point (or anchor) to understand or predict what another person thinks, feels or prefers. This

Light and ultrasound reveal renewable routes to compounds for pharmaceutical research
Sustainable packaging is only the beginning. What a medicine is made from—and how its ingredients are produced—matters just as much. Yet the synthesis of compounds for pharmaceutical research can still depend on fossil feedstocks, high temperatures, strong oxidants and metals tha

World-record intensity in attosecond hard-X-ray pulses could unlock closer study of electrons in atoms and molecules
Researchers used the European XFEL to create X-ray flashes that were not only extremely short but also reached record intensity for this type of pulse. The researchers focused the X-rays to an area roughly 100,000 times smaller than the cross section of a typical human hair. This
