Dog puppies spontaneously match human actions, while kittens and wolf pups don't
According to a new study published in Scientific Reports puppies—but not kittens and wolf pups—tend to spontaneously imitate human actions, even when they are not rewarded with food (or toys). The researchers of the Department of Ethology at Eötvös Loránd University (ELTE), Budapest, investigated whether young puppies, kittens and wolf pups have different tendencies to observe and imitate what a p

It is a popular notion that aside from large celestial objects like planets, stars and asteroids, outer space is empty. In fact, galaxies are filled with something called the interstellar medium (ISM)—that is, the gas and dust that permeate the space in between those large objects. Importantly, under the right conditions, it is from the ISM that new stars are formed.

Better understanding of craniofacial birth defects opens new roads for regenerative medicine
Craniofacial birth defects, including cleft lip and palate, are among the most common human congenital malformations. These craniofacial anomalies occur because of defects in neural crest cells, whose role is to give rise to the complex craniofacial region by generating multiple cell types, including bone, cartilage and the peripheral nervous system.

An extension of the memristive system: From tunable conductance to reconfigurable photoresponse
In traditional vision systems, the optical information is captured by a frame-based digital camera, and then the digital signal is processed afterwards using machine-learning algorithms. In this scenario, a large amount of data (mostly redundant) has to be transferred from a standalone sensing elements to the processing units, which leads to high latency and power consumption.

European summer droughts since 2015 most severe in centuries, but multi-year droughts also happened in the past
The 2015–2018 summer droughts have been exceptional in large parts of Western and Central Europe over the last 400 years, in terms of the magnitude of drought conditions. This indicates an influence of man-made global warming. However, multi-year droughts have occurred frequently in the 17th and 18th century, although not as severe.

Future observations will help determine what is responsible for the shape and motion of the Tadpole.

Who Poisoned Pablo Neruda?
Repressive regimes tend to be unimaginative. They persecute and censor their opponents, herd them into concentration camps, torture and execute them in ways that rarely vary from country to country, era to era.

Judging Parents Online Is a National Sport
To be a parent on the internet is to be constantly accused of false advertising.

How to Beat Trump in a Debate
Donald Trump is probably unaware that he's an avid practitioner of a debating method known among philosophers and rhetoricians as the Gish Gallop.

Trump owes much of his political success to this tactic—and to the fact that so few people know how to beat it. Although his 2024 c

Like the neurons firing in human brains, bacteria use electricity to communicate and respond to environmental cues. Now, researchers have discovered a way to control this electrical signalling in bacteria, to better understand resistance to antibiotics.
New technique maps large-scale impacts of fire-induced permafrost thaw in Alaska
Researchers have developed a machine learning-based ensemble approach to quantify fire-induced thaw settlement across the entire Tanana Flats in Alaska, which encompasses more than 3 million acres. They linked airborne repeat lidar data to time-series Landsat products (satellite images) to delineate thaw settlement patterns across six large fires that have occurred since 2000. The six fires result
Social isolation triggers astrocyte-mediated deficits in learning and memory
In animal models, social isolation triggers memory and learning deficits that are mediated by hyperactivity of the most abundant brain cell, the astrocyte. Importantly, inhibiting this hyperactivity reversed the cognitive deficits associated with social deprivation.

Ginger Compound Puts
Ginger has a reputation for stimulating the immune system. New results now support this thesis. In laboratory tests, small amounts of a pungent ginger constituent put white blood cells on heightened alert. The study also shows that this process involves a type of receptor that plays a role in the perception of painful heat stimuli and the sensation of spiciness in food.

With La Niña Poised to Leave the Stage, is El Niño Now Waiting in the Wings?
If the mom and pup Galápagos sea lions in the photo above seem content, it could be that we're simply projecting human emotions onto them.

Giant meat-eating dinosaur footprint is largest found in Yorkshire
An almost meter-long footprint made by a giant, meat-eating theropod dinosaur from the Jurassic Period represents the largest of its kind ever found in Yorkshire. Curiously, the unusual footprint appears to capture the moment that the dinosaur rested or crouched down some 166 million years ago.
Novel method to accurately measure key marker of biological aging
Telomeres—the caps at the ends of chromosomes that protect our genetic materials from the brunt of cellular wear and tear—are known to shorten and fray over time. Lifestyle, diet and stress can exacerbate this process, leading to early loss of telomere protection and increasing the chances of early aging and diseases, such as cancer and heart disease.

Simple test predicts if a steroid shot will ease neck pain
A quick clinical test can predict which people with neck pain are more likely to benefit from epidural steroid injections, researchers report. These injections deliver drugs directly around the spinal nerves to stop nerve inflammation and reduce pain. The uncomfortable injections are a common treatment for neck pain, but can cost hundreds of dollars each, carry risks, and help only a minority of
Climate change disrupts core habitats of marine species, finds modeling study

Insects are vanishing worldwide—now it's making it harder to grow food
Over the past 20 years a steady trickle of scientific papers has reported that there are fewer insects than there used to be.

Some studies were based on sightings by amateur entomologists, while others involved scientists counting the number of bugs splattered on car windshields. Some collected f
Insect bite marks show first fossil evidence for plants' leaves folding up at night
Plants can move in ways that might surprise you. Some of them even show "sleep movements," folding or raising their leaves each night before opening them again the next day. Now, researchers reporting in the journal Current Biology on February 15 offer the first convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years

Four classes of planetary systems
Astronomers have long been aware that planetary systems are not necessarily structured like our solar system. Researchers have now shown that there are in fact four types of planetary systems.
Kangaroo fecal microbes could reduce methane from cows
Baby kangaroo feces might help provide an unlikely solution to the environmental problem of cow-produced methane. A microbial culture developed from the kangaroo feces inhibited methane production in a cow stomach simulator. After researchers added the baby kangaroo culture and a known methane inhibitor to the simulated stomach, it produced acetic acid instead of methane. Unlike methane, which cat
Rats trade initial rewards for long-term learning opportunities
Scientists have provided evidence for the cognitive control of learning in rats, showing they can estimate the long-term value of learning and adapt their decision-making strategy to take advantage of learning opportunities.
On-demand male contraceptive shows promise in preclinical study
An experimental contraceptive drug temporarily stops sperm in their tracks and prevents pregnancies in preclinical models. The study demonstrates that an on-demand male contraceptive is possible.
Barns sportande har blivit allt mer tävlingsinriktat
Idrottsföreningar har gått från folkrörelse till en angelägenhet för engagerade föräldrar. Men många barn- och ungdomar tappar sugen för idrott när träningen både tar upp tid och blivit mer tävlingsinriktad. Inlägget dök först upp på forskning.se .
Love and the Brain: How Attached Are We to Attachment Styles?
Are you "anxious," "avoidant" or "disorganized?" So-called attachment styles have taken the Internet by storm. But it turns out there's a lot more to unpack than people think.
