How to enhance or suppress memories
Erasing memories concept. Credit: © Andrea Danti / Adobe Stock What if scientists could manipulate your brain so that a traumatic memory lost its emotional power over your psyche? Steve Ramirez, a Boston University neuroscientist fascinated by memory, believes that a small structure in the brain could hold the keys to future therapeutic techniques for…
Oldest meteorite collection on Earth found in one of the driest places
Meteor illustration (stock image). Credit: © Vadimsadovski / Adobe Stock Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding enough meteorites scattered on the planet's surface can be challenging, especially if you are interested in reconstructing how frequently they land. Now, researchers have uncovered a…

Chimpanzee (stock image). Credit: © Uryadnikov Sergey / Adobe Stock An international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig and the University of Osnabrück, Germany, have observed wild chimpanzees in the Loango National Park, Gabon, eating tortoises. They describe the first observations of this potentially cultural behavior where chimpanzees…
A family of comets reopens the debate about the origin of Earth’s water
Illustration of comet over Earth (stock image). Credit: © Paul Fleet / Adobe Stock Where did the Earth's water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their water differs from that in our oceans. Now, however, an international team, bringing together CNRS researchers at…

A binational team of researchers led by the University of California, Davis, has conducted the first comprehensive study…
How corn’s ancient ancestor rejects crossbreeding
Corn varieties (stock image). Credit: © cpnjuansanchez / Adobe Stock Determining how one species becomes distinct from another has been a subject of fascination dating back to Charles Darwin. New research led by Carnegie's Matthew Evans and published in Nature Communications elucidates the mechanism that keeps maize distinct from its ancient ancestor grass, teosinte. Speciation…
Simple test can tell if you’re stressed out
Stress concept. Credit: © boygostockphoto / Adobe Stock Stress is often called "the silent killer" because of its stealthy and mysterious effects on everything from heart disease to mental health. Now researchers at the University of Cincinnati have developed a new test that can easily and simply measure common stress hormones using sweat, blood, urine…
Phase transitions: The math behind the music
Sound word cloud. Credit: © CrazyCloud / Adobe Stock Next time you listen to a favorite tune or wonder at the beauty of a natural sound, you might also end up pondering the math behind the music. You will, anyway, if you spend any time talking with Jesse Berezovsky, an associate professor of physics at…
Geometry of an electron determined for the first time
Quantum computing concept (stock image). Credit: © metamorworks / Adobe Stock Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved…
Temperature alters developing nervous system in frogs, study shows
African clawed frog (stock image). Credit: © Brandy McKnight / Adobe Stock Can the environment affect how the spinal cord develops specialized circuitry, or is that process hardwired, following prescribed genetic instructions turned on early in the embryo? A UC Davis study that compared the effects of cold and warm temperatures on the development of…

Marmot family. Credit: © Astrid Gast / Adobe Stock What effects does climate change have on the genetic diversity of living organisms? In a study led by Charité -- Universitätsmedizin Berlin, an international team of researchers studied the genome of the alpine marmot, an ice-age remnant that now lives in large numbers in the high…
Egyptian fruit bats trade food for sex
Egyptian fruit bat (stock image). Credit: © seregraff / Adobe Stock Female Egyptian fruit bats living in captivity will consistently take food right from the mouths of their male peers. Now the Tel Aviv University team that made that discovery is back with new evidence to explain why the males put up with it. As…
If you could learn every disease your child could possibly develop in life, would...
Genetic screening word cloud. Credit: © ibreakstock / Adobe Stock Newborn screening is required in the U.S. and differs slightly depending on which state you live in. For the most part, it's done before a newborn baby leaves the hospital and includes a blood test that screens for 30-50 serious health problems that usually arise…

New leaf shapes for thale cress
Arabidopsis thaliana (stock image). Credit: © lenswideopen / Adobe Stock Anyone who looks at their bowl of salad or at their garden can see how different the shapes of leaves can be. Spinach leaves, for example, have smooth edges and are comparatively simple in form, while parsley leaves are deeply notched and complex, apparently composed…
Meteor magnets in outer space: Finding elusive giant planets
Jupiter. Credit: © allexxandarx / Adobe Stock Astronomers believe planets like Jupiter shield us from space objects that would otherwise slam into Earth. Now they're closer to learning whether giant planets act as guardians of solar systems elsewhere in the galaxy. A UCR-led team has discovered two Jupiter-sized planets about 150 light years away from…
