Every egg cell and sperm cell depends on meiosis, a tightly choreographed process in which chromosomes find their partners, exchange genetic material and then divide. When meiosis goes awry in humans, the consequences can ...
They can turn up in a nonstick frying pan, a waterproof jacket, a takeout food wrapper or the foam used to fight fires. Known as "forever chemicals," these substances are ubiquitous in modern society, prized for their extreme ...
Microgreens are nutritional powerhouses. A team of plant scientists at Penn State conducting research on multiple aspects of microgreens recently published three studies reporting progress on multiple fronts, including iron ...
Ten years ago, in 2016, a metal detectorist came upon a hoard of gold. It had been buried in the dirt for around 1,800 years and consisted of around 396 grams (14 ounces) of gold rings. The detectorist handed in his finds ...
DNA is not randomly distributed within the nucleus but is packaged with proteins into chromatin, which is precisely folded into complex three-dimensional structures. However, scientists have not fully understood how this ...
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 ...
A seven-minute virtual reality (VR) intervention can help students feel calmer, less anxious and better able to cope with academic pressure, according to new research from City St George's. The findings, published in Scientific ...
Over the past 30 years, Swiss barn owls have become more reddish-brown and more heavily spotted. By analyzing the genomes of more than 3,000 birds, scientists at the University of Lausanne identified the genetic variants ...
Some supermassive black holes rapidly consume surrounding matter while simultaneously firing powerful streams of plasma into space at nearly the speed of light. However, this creates a physical puzzle: rapid feeding is expected ...
Earthquakes and the seismic waves they generate provide some of the best clues to Earth's interior. To extend that success to other worlds, scientists placed seismometers on the Apollo missions to the moon and on the Viking ...
