In a new study Indiana University researchers observed episodic memory in rats to a degree never documented before, suggesting that rats can serve as a model for complex cognitive processes often considered exclusively human. Unlike semantic memory, which involves isolated
A new three-way bond-breaking and making mechanism makes the synthesis of five-membered rings easier than before.
Organic chemistry is packed with rules about structure and reactivity, especially when it comes to making and breaking chemical bonds. The rules governing how these bonds, which hold atoms together in molecules, form and the shapes they give molecules are often thought to be
Skoltech researchers and their colleagues from Ludwig Maximilian University of Munich, Germany, Nanjing University of China, and the National Institute for Materials Science of Japan have developed a method for depositing organic molecules on a two-dimensional semiconductor in
Ancient pine trees growing in the Iberian mountains of eastern Spain have quietly recorded more than five centuries of Mediterranean weather. Now, by reading the annual growth rings preserved in their wood, scientists have uncovered a striking message: today's storms and
Predicting the duration of a Central Pacific El Niño event has long frustrated climate scientists and forecasters. Now, a new study reveals that Central Pacific El Niños follow two fundamentally different life cycles—and the difference is determined months before they peak.
Graphene has drawn attention as a scientific curiosity owing to its record conductivities, strength and thermal properties. But now, it's starting to make its way into a number of real-world applications, from batteries to concrete, sensors and material composites. Its market
It's Saturday! This week, in an eminently practical analysis of the Boltzmann brain conjecture, physicists put constraints on the idea that memories could arise from random fluctuations in entropy rather than reflecting the actual past of the universe—news you can use!
Radio images captured this “cosmic volcano” being reborn at the heart of the galaxy J1007+3540
As deepfakes blur the line between truth and fiction, we’ll need a new class of forensic experts to determine what’s real, what’s fake and what can be proved in court
Americans stripped supermarket shelves Friday ahead of potentially "catastrophic" winter weather that threatened at least 160 million people across the country with transportation chaos, blackouts and life-threatening cold.
Editor in Chief Nancy Shute discusses how scientists are beginning to study animals’ emotions and personalities — from joy to individual temperament.
In one day, 433 people won the Philippine lottery jackpot. What were the chances?
Smartphone weather apps that summarize their forecasts with eye-popping numbers and bright icons may be handy during mild weather, but meteorologists say it's better to listen to human expertise during multi-faceted, dangerous winter storms like the one blowing through the U.S.
From a social sciences perspective, people with radical, extremist, or fundamentalist attitudes are similar in some respects: In most cases, they are younger and less educated men who feel that they are not taken seriously enough. This is one of the key findings of a research
Scientists are finding new ways to replace expensive, scarce platinum catalysts with something far more abundant: tungsten carbide. By carefully controlling how tungsten carbide’s atoms are arranged at extremely high temperatures, researchers discovered a specific form that can
A groundbreaking new radio image reveals the Milky Way in more detail than ever before, using low-frequency radio “colors” to map the galaxy’s hidden structures. The image is sharper, deeper, and wider than anything previously released, uncovering both star-forming regions and
Astronomers have spotted a rare, rule-breaking quasar in the early Universe that appears to be growing its central black hole at an astonishing pace. Observations show the black hole is devouring matter far faster than theory says it should—about 13 times the usual “speed
In the same week that New South Wales experienced four shark attacks, Victorian beachgoers were warned about stinging jellyfish.
Giant kangaroos that lived during the Ice Age may not have been as slow and grounded as once believed. A new study finds their leg bones and tendons were likely strong enough to support hopping, despite their massive size. Rather than traveling this way all the time, these
Chemotherapy’s gut damage turns out to have a surprising upside. By changing nutrient availability in the intestine, it alters gut bacteria and increases levels of a microbial molecule that travels to the bone marrow. This signal reshapes immune cell production, strengthening
An animal ecologist researching large marine animals such as whales and dolphins, Assistant Professor Iwata Takashi of the Graduate School of Maritime Sciences has performed surveys in oceans across the world. By using a method known as "biologging," which involves attaching
When we assign work or chores in social units like our workplaces and households, feelings of unfairness are inevitable. While we hope to keep things fair, this can sometimes be difficult to achieve, and we often find ourselves caught in terrible dilemmas.
With western states deadlocked in negotiations over how to cut water use along the Colorado River, the Trump administration has called in the governors of seven states to Washington to try to hash out a consensus.

Researchers have identified a new physicochemical principle governing liquid–liquid phase separation in polymer solutions. Their research demonstrates that during the separation of a polymer mixture into two fluid phases, coexisting ions are unequally distributed between the
A drug that kills cancer cells by puncturing them comes with an additional benefit: tests in mice suggest it reduces the growth of pain-sensing nerves around tumours
An international research team led by Prof. Dr. Sedat Nizamoğlu from the Department of Electrical and Electronics Engineering at Koç University has developed a next-generation, safe, and wireless stimulation technology for retinal degenerative diseases that cause vision loss.
