How we mark our ballot can affect how we feel about voting. Here's why
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.
Nearly 3,000 exploding stars challenge our understanding of the Universe
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.
Beyond hearing: Sensing when conversation becomes difficult
About six years ago, hearing researcher Dr. Kelly Miles had a stroke just a week after having a baby.
Cambridge scientists create a $10 chip that could put a medical lab on your wrist
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...
Chinese astronomers find real 3-body system. It is not what Liu Cixin thinks
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...
New test measures potentially harmful metals in cellulose food packaging
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.
Autonomous triangular modules could build tomorrow's mega-observatories
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 ...
Researchers develop AI tool to map microRNA binding sites on circular RNAs
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...
Acupuncture and mutual exchange in Chinese and Soviet science
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 ...
Light-activated catalyst makes sustainable production of hydrogen peroxide more efficient
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...
Material substitution can increase the potential environmental impact of packaging systems
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.
What is a neutrino anyway? A look at the science behind this year's Nobel Prize in Physics
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 ...

Revamped playground design could protect children around the world from dangers of the sun
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.
Grid operator says lights will stay on this winter after concerns
The assurance from the National Energy System Operator comes amid concern from its engineers about their ability to ensure adequate supply.
Heat Waves Killed an Estimated 50,000 in European Cities, a Likely Record
This summer’s heat was the continent’s deadliest by far this century, according to new peer-reviewed estimates.
Ultrafast light pulses track molecular motion with three-femtosecond resolution
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...
Shrinking iron films strengthens laser-driven demagnetization
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?
Researcher tackles impact of a CMO's life events on businesses' bottom line
When a major company's CEO goes through a messy divorce or is arrested for drunk driving, investors often get nervous, worried that the executive's personal struggles will dent their returns. But most people hardly notice when a chief marketing officer has similar personal problems.
Global database provides a fuller picture of the elements that make up plant life
What, exactly, is a plant made of? Scientists have a good understanding of the essential nutrients plants need to grow. But what plants need and what they contain are not necessarily the same.
I’m buying this heated blanket for 40% off at Amazon and resisting the urge to turn on my heat before November
Bedsure’s Amazon sale has heated throws, sherpa blankets, and wearable blankets that cost much less to run than a space heater. The post I’m buying this heated blanket for 40% off at Amazon and resisting the urge to turn on my heat before November appeared first on Popular Science .
Supramolecular assembly opens a new route to building quantum materials
A joint research team fabricated a two-dimensional structure that exhibits properties of both the honeycomb and Kagome lattices using organic molecules. They discovered that edge states specific to topological materials (states that exist only at the edges and are distinct from those in the inte...
How farming helped cause two medieval tsunamis in an Italian lake—and why the danger has returned
On Jan. 3, 1117, a strong earthquake shook northern Italy. A manuscript of the 12th century, kept today in the Vatican Library, recorded what came next: "The lakes also rose so much that very few of those living in the villages nearby escaped this danger.
