How recurrent fluorescence helps organic molecules survive extreme interstellar conditions

How recurrent fluorescence helps organic molecules survive extreme interstellar conditions

The James Webb Space Telescope (JWST) has unlocked the depths of interstellar space with unprecedented clarity, offering humanity a high-resolution window into the cosmos. Harnessing this newfound capability, an international team of researchers set out to investigate how polycyclic aromatic hydrocarbons (PAHs)—organic molecules and key players in cosmic chemistry—survive the harsh conditions of space and uncover the mechanism behind their resilience.

A new problem that only quantum computing can solve

A new problem that only quantum computing can solve

As quantum computing develops, scientists are working to identify tasks for which quantum computers have a clear advantage over classical computers. So far, researchers have only pinpointed a handful of these problems, but in a new paper published in Physical Review Letters, scientists at Los Alamos National Laboratory have added one more problem to this very short list.

Unprecedented dataset of molecular simulations to train AI models released

Unprecedented dataset of molecular simulations to train AI models released

A collaborative effort between Meta, Lawrence Berkeley National Laboratory and Los Alamos National Laboratory leverages Los Alamos' expertise in building tools for molecular screening capabilities. The release of "Open Molecules 2025", an unprecedented dataset of molecular simulations, can accelerate opportunities for machine learning to transform research in fields such as biology, materials science and energy technologies.

Ultrafast spin-exchange in quantum dots enhances solar energy and photochemical efficiency

Ultrafast spin-exchange in quantum dots enhances solar energy and photochemical efficiency

Quantum dots are microscopic semiconductor crystals developed in the lab that share many properties with atoms, including the ability to absorb or emit light, a technology that Los Alamos researchers have spent nearly three decades evolving. Through carrier multiplication, in which a single absorbed photon generates two electron-hole pairs, called excitons, quantum dots have the unique ability to convert photons more efficiently to energy.

The Saimaa ringed seal is a species of its own, study says

The Saimaa ringed seal is a species of its own, study says

A study published in the Proceedings of the National Academy of Sciences reveals that the Saimaa ringed seal is evolutionarily more differentiated than previously known. In fact, the study suggests that, instead of a subspecies, the Saimaa ringed seal should be acknowledged as a species of its own.

Cellular coordinate system reveals secrets of active matter

Cellular coordinate system reveals secrets of active matter

All humans who have ever lived were once each an individual cell, which then divided countless times to produce a body made up of about 10 trillion cells. These cells have busy lives, executing all kinds of dynamic movement: contracting every time we flex a muscle, migrating toward the site of an injury, and rhythmically beating for decades on end.

Cancer cells use cholesterol armor to survive heat shock treatment, study discovers

Cancer cells use cholesterol armor to survive heat shock treatment, study discovers

Since the time of the ancient Greek physician Hippocrates, cancer has been recognized as being sensitive to heat. Today, this principle forms the basis of hyperthermia treatment—a promising cancer therapy that uses controlled heat to kill tumor cells while sparing healthy ones.

New simulations show how much colder European winters would get if AMOC collapses

New simulations show how much colder European winters would get if AMOC collapses

A pair of meteorologists in the Netherlands has used new simulations to show just how cold many of Europe's cities could get if the Atlantic Meridional Overturning Circulation (AMOC) were to collapse due to global warming. In their study, published in the journal Geophysical Research Letters, René van Westen and Michiel Baatsen developed a climate model based on a range of ocean temperature changes that could arise due to global warming.
