In the deepest region of the Earth's mantle, just above the core, much of the material consists of crystals of magnesium oxide. In larger rocky exoplanets called super-Earths, the higher pressures in the lower mantle may drive magnesium oxide to transform into a new high-pressure crystal structu...
A Times journalist and animal lover spent a day at a Royal Canin facility to understand how pet food giants are studying the taste buds of dogs and cats.
A mother bat has one crucial challenge: find her own babies among hundreds of other bats in the colony. Making sure she cares for and nurses only her own offspring is important to ensuring their survival. Among Japanese house bats, mothers keep track of their pups using the babies' isolation ca...
They can even pick out their offspring’s distress cries amongst thousands of bats. The post Bat mothers’ hearts beat faster when they hear their pups appeared first on Popular Science .
Forty years after the Chornobyl disaster, tiny radioactive particles still linger in the soil, carrying a dangerous legacy. Using powerful X-rays, scientists discovered that some of these particles have remained surprisingly stable, trapping radioactive substances inside instead of releasing the...

Have you ever left a polling place feeling that your mark on the ballot didn't quite say what you wanted it to? Perhaps you liked two candidates but had to drop one, or backed the one who might actually win over the one you preferred.
A massive analysis of 2,884 exploding stars has uncovered new evidence that dark energy, the mysterious force accelerating the universe’s expansion, may change over time. The findings challenge a cornerstone of modern cosmology and could reshape our understanding of how the universe works.
About six years ago, hearing researcher Dr. Kelly Miles had a stroke just a week after having a baby.
Cambridge researchers have created a groundbreaking $10 optical sensor that delivers the precision of laboratory equipment in a device small enough for wearable technology. It identified foods, plastics, and medicines with 100% accuracy in tests and demonstrated the ability to monitor blood gluc...
In author and computer engineer Liu Cixin’s science fiction hit The Three-Body Problem, three suns throw a doomed world into chaos. Chinese astronomers say they have found a real three-star system that is far better behaved. Using FAST, the world’s biggest single-dish radio telescope in southwe...
A technique for detecting potentially harmful metals in regenerated cellulose food packaging is discussed in the International Journal of Environment and Pollution. The new tool can be used for safety assessments of materials increasingly used as alternatives to conventional plastics.
Private companies are getting better at launching more mass into space with larger rockets. But there is still a major constraint on the size of objects we can get into orbit—fairing size. This places physical constraints on the overall shape of what we can launch and severely limits the sizes ...
Circular RNAs (circRNAs) are loop-shaped molecules that can influence gene regulation through interactions with microRNAs (miRNAs). This matters because circRNAs can exist as different full-length isoforms, and their back-splice junction (BSJ) connects the two ends of the RNA. Treating a circul...
Previous accounts of the scientific relationship between communist China and the Soviet Union have depicted it as one of subordination, with the Russians exporting knowledge to the Chinese or scavenging from their bodies of knowledge. A new article in Isis, however, posits that the relationship ...
Hydrogen peroxide (H₂O₂) is a versatile chemical feedstock whose industrial production relies predominantly on an energy-intensive process with a substantial environmental footprint. One alternative is to produce it using a catalyst activated by light. In an international research project invol...
New research suggests that replacing polyethylene (PE) packaging with paper, glass, aluminum or steel often does not reduce environmental impacts across a product's life cycle.
If you wanted a Nobel Prize, you would do well to study neutrinos. To date, the Nobel Prize in Physics has been awarded five times to research related to neutrino detection and discovery. This year, Francis Halzen earned the Nobel "for decisive contributions to the IceCube Neutrino Observatory ...

A new design methodology for school playgrounds is demonstrating how children can still enjoy their playtime while being protected from the harmful effects of the sun.
The assurance from the National Energy System Operator comes amid concern from its engineers about their ability to ensure adequate supply.
This summer’s heat was the continent’s deadliest by far this century, according to new peer-reviewed estimates.
Researchers have observed a molecule in the first instants after it has absorbed light and tracked the coordinated motion of electrons and nuclei with a temporal resolution of three femtoseconds. This is the result achieved by an international research group led by the Politecnico di Milano, whi...
From photos and videos to documents, vast amounts of data are stored on hard drives in large data centers. These devices use tiny magnetic regions whose orientation determines the information stored. But how could data be stored even faster in the future?
