A team of researchers from the University of Rochester and the Israeli-based Interdisciplinary Center Herzliya examined the effects of playing hard to get, a mating strategy that is likely to instill a certain degree of uncertainty. In a new study they show that making the chase harder increases a potential mate's desirability.
On The Run Many moons, including our own, gradually creep farther and farther out into space. And while these celestial escapes occur at nearly imperceptibly-slow paces, NASA researchers just found out that Saturn’s moon Titan is escaping at 100 times the pace they had previously thought — a discovery that could force astronomers to make a sharp adjustment to their understanding of our solar syst
Researchers at the University of Missouri and the University of Essex in the United Kingdom found boys' poor reading skills in adolescence, combined with the social attitudes about women attending college, can help explain why fewer men than women enroll in higher education or other types of post-high school education.
A new medium that mimics the conditions of the human body opens the door for testing antibiotics against infections other than what they are typically used for.
The first 1,000 COVID-19 patients treated at a NYC medical center had more kidney complications than other patient groups, two peaks in time from symptom onset to intubation.
By Earthly standards, Saturn's moon Titan is a strange place. Larger than the planet Mercury, Titan is swaddled in a thick atmosphere (it is the only moon in the solar system to have one) and covered in rivers and seas of liquid hydrocarbons like methane and ethane. Beneath these is a thick crust of water ice, and beneath that may be a liquid water ocean that could potentially harbor life.

When stars explode as supernovas, they produce shock waves in the plasma surrounding them. So powerful are these shock waves, they can act as particle accelerators that blast streams of particles, called cosmic rays, out into the universe at nearly the speed of light. Yet how exactly they do that has remained something of a mystery.
Marine scientists from around the world spent the last four years reviewing numerous studies and other data on the possible environmental effects of marine renewable energy (MRE) devices and found that the potential impact to marine life is likely small or undetectable.
It's not often in nuclear physics that you can clearly get both sides of the story, but a recent experiment allowed researchers to do just that. They compared very similar nuclei to each other to get a clearer view of how the components of nuclei are arranged and found that there's still more to learn about the heart of matter. The research, carried out at the Department of Energy's Thomas Jeffers

At a protest in Queens, I asked a police officer why he wasn’t wearing a mask. “Corona’s over,” he replied. As Black Lives Matter protests against police violence and systematic racism erupted across the country, an unfortunate trend has emerged: while police often show up heavily armed and wearing riot gear , they seldom wear medical masks or other face coverings to prevent COVID-19 from spreadi
Color awareness has long been a puzzle for researchers in neuroscience and psychology, who debate over how much color observers really perceive. A study from Dartmouth in collaboration with Amherst College finds that people are aware of surprisingly limited color in their peripheral vision; much of our sense of a colorful visual world is likely constructed by our brain. The findings are published
Dating archaeological objects precisely is difficult, even when using techniques such as radiocarbon dating.

By effectively measuring these "cosmic pants," the researchers
A hallmark of the strong force at the Large Hadron Collider (LHC) is the dramatic production of collimated jets of particles when quarks and gluons scatter at high energies. Particle physicists have studied jets for decades to learn about the structure of quantum chromodynamics—or QCD, the theory of the strong interaction—across a wide range of energy scales.
