Plutonium isotope anomalies discovered in Southern Hemisphere glaciers
The results of the newest investigations carried out by scientists from the Institute of Nuclear Physics PAN shed new light on the processes of accumulation of plutonium isotopes on glaciers of the Southern Hemisphere. Analyses of samples of cryoconi.....»»
Enzymes evolved mix-and-match characteristics to shape nitrogen metabolism diversity across the planet
To boost crops more efficiently in the future, the evolutionary past may hold key insights. The way that plants process nutrients has a rich back story—they rely on enzymes that have been evolving for billions of years. However, these enzymes are o.....»»
Tidal streams of interstellar objects may flow through the Milky Way like braided rivers
We know that interstellar objects occasionally visit our solar system. So far, we have only discovered two interstellar objects (ISOs), but that's mainly because we can only distinguish them from solar system bodies by their orbital motion, and that.....»»
New model find molecular interactions key to creating order in active systems
Non-reciprocal interactions can increase the order in an active system. This is the finding of a study by scientists from the department of Living Matter Physics at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS)......»»
New insights into the evolution and paleoecology of mosasaurs
Mosasaurs are extinct marine lizards, spectacular examples of which were first discovered in 1766 near Maastricht in the Netherlands, fueling the rise of the field of vertebrate paleontology. Paleontologist Michael Polcyn presented the most comprehen.....»»
Neuronal adaptations shed light on anglerfish hunting behavior
Characterized by their unique adaptations to extreme environments, anglerfish are known for using lures to attract prey. Researchers at Nagoya University in Japan have discovered in frogfish (a subgroup of anglerfish) a specialized motor neuron popul.....»»
Helicopter parenting in fish: Damselfish protect young by eating parasites
Researchers have discovered a rare example of "great fish parenting" with a common coral reef species found to actively protect their young by eating parasites......»»
Fast, rewritable computing with DNA origami registers
DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are fast.....»»
Warm Saturn-sized exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet orbiting a distant star. The newfound alien world, designated TOI-4994 b, is warm and slightly smaller than Saturn. The findi.....»»

Method enhances solubility of pea protein for use in food and beverages
Research conducted at the State University of Campinas (UNICAMP) in São Paulo state, Brazil, shows that heat treatment of pea protein and addition of guarana extract result in a compound with significant potential to be used as an ingredient of plan.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
