Astronomers discover a luminous nuclear transient
Using NASA's Swift spacecraft, an international team of astronomers has discovered a luminous and slowly-evolving nuclear transient event. The origin of the newly detected transient, designated Swift J221951-484240, is yet to be determined. The findi.....»»
Strictly no dancing: Researchers discover "new molecular design rules"
Since the discovery of quantum mechanics more than a hundred years ago, it has been known that electrons in molecules can be coupled to the motion of the atoms that make up the molecules. Often referred to as molecular vibrations, the motion of atoms.....»»
Researchers discover new function of oncoproteins
Researchers at the University of Würzburg have discovered a new function of the oncoprotein MYCN: It not only helps cancer cells to grow stronger, but also makes them more resistant to drugs. The study is published in Molecular Cell......»»
Astronomers explore globular cluster NGC 2419
Using the Indian Astronomical Observatory (IAO) and ESA's Gaia satellite, astronomers have explored a galactic globular cluster known as NGC 2419. Results of the study, published April 29 on the preprint server arXiv, shed more light on the propertie.....»»
Researchers discover three ingots made of Roman lead in Northern Córdoba
Three ingots from the site of Los Escoriales de Doña Rama (Belmez) and dating from the Roman era demonstrate the importance of lead production and exportation in northern Córdoba. Measuring some 45 centimeters long and weighing between 24 and 32 ki.....»»
Proton-lithium interactions model lays the foundation for unlocking the secrets of stellar reactions
The reactions between protons and lithium isotopes, especially lithium-6, are pivotal for several domains ranging from nuclear energy applications to astrophysics. The detailed understanding of these interactions aids in improving models for neutron.....»»
How NASA"s Roman mission will hunt for primordial black holes
Astronomers have discovered black holes ranging from a few times the sun's mass to tens of billions. Now a group of scientists has predicted that NASA's Nancy Grace Roman Space Telescope could find a class of "featherweight" black holes that has so f.....»»
Hackers discover how to reprogram NES Tetris from within the game
New method could help high-score chasers trying to avoid game-ending crashes. Enlarge / I can see the code that controls the Tetri-verse! (credit: Aurich Lawson) Earlier this year, we shared the story of how a classic NE.....»»
Researchers discover spontaneous liquefaction of solid metal–liquid metal interfaces in colloidal binary alloys
The boundary between solid metal and liquid metal can be much less "solid" than we ever suspected. RMIT researchers have discovered that the liquid-solid boundary can fluctuate back and forth, with metallic atoms near the surface breaking free from t.....»»
Attosecond core-level spectroscopy reveals real-time molecular dynamics
Chemical reactions are complex mechanisms. Many different dynamic processes are involved, affecting both the electrons and the nucleus of the present atoms. Very often, the strongly coupled electron and nuclear dynamics induce radiation-less relaxati.....»»
Collaboration identifies rare nuclear decay in long-lived potassium isotope
Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This isotope usually decays to calcium-40, but about 10%.....»»
Astronomers observe elusive stellar light surrounding ancient quasars
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues to how the very first black.....»»
Radio astronomers bypass disturbing Earth"s atmosphere with new calibration technique
An international team of researchers led by astronomers from Leiden University (Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Eart.....»»
Male or female? Scientists discover the genetic mechanism that determines sex development in butterflies
Scientists of the Biology Centre, Czech Academy of Sciences, in collaboration with University of Liverpool have found the genetic mechanism that determines whether individuals of the butterfly species Bicyclus anynana become male or female......»»

Astronomers inspect population of young stellar objects in open cluster NGC 346
Using the James Webb Space Telescope (JWST), an international team of astronomers has explored young stellar objects (YSOs) in an open cluster known as NGC 346. The study, published April 24 on the preprint server arXiv, yields crucial information ab.....»»
New Nevada experiments aim to improve monitoring of nuclear explosions
On an October morning in 2023, a chemical explosion detonated in a tunnel under the Nevada desert was the launch of the next set of experiments by the National Nuclear Security Administration, with the goal to improve detection of low-yield nuclear e.....»»
