Single photon reveals the secrets of a single molecule
Scientists have reconstructed the infrared spectrum of a single molecular ion by detecting the effect of a single absorbed photon on a neighbouring calcium ion.

CERN finds particle that eluded physicists for years
The LHCb experiment at CERN has confirmed for the first time the existence of the Ξcc⁺ baryon, a particle made up of two heavy charm quarks and one down quark. Physicists had predicted its existence years ago, but an earlier possible detection was never confirmed. The new signal exceeded seven standard deviations.

Glowing bacteria tested as tiny lamps for hydrogen production
Scientists have tested whether glowing bacteria could act as tiny lamps inside reactors producing hydrogen - but their light proved almost 43 times too weak.

New material glows orange when hit by sound, friction or impact
A new material developed by Polish physicists can be made to glow orange simply by striking, rubbing or hitting it with ultrasound. Physicists from the University of Gdańsk attribute the effect to the release of charges trapped in crystal defects.

Scientists create tiny molecular motors powered by ordinary daylight
Scientists have developed a new family of molecular machines that can convert the energy of ordinary sunlight into unidirectional rotational motion with exceptional efficiency.

Scientists measure temperatures 268C below zero using light as a thermometer
Scientists have measured temperatures as low as 4.9 kelvins — about 268 degrees Celsius below zero — by tracking the motion of hydrogen molecules with light instead of using a conventional thermometer.

More pressure can make your espresso flow slower, Polish physicists find
Press a button, a few seconds of whirring, and your morning espresso is ready. But does more pressure always mean a faster flow? Polish physicists have found that, instead of simply speeding up the brew, higher pressure can compress the coffee grounds and act like a tighter cork.

Scientists develop 'smart' material that glows under friction, heat and ultrasound
An international team of scientists, including researchers from Poland, has developed a new material that emits light when exposed to friction, impact, heat and even ultrasound.

AI can't replace mathematical thinking, Polish study warns
Artificial intelligence and advanced mathematical software can solve increasingly complex equations, but engineers who rely on them without understanding the mathematics behind the answers risk making poor or even unsafe decisions, according to new research from Poland.
