While we’re not yet close to replicating the complexity and the intricacy of the human brain with anything artificial, scientists are making progress with certain dedicated devices – like a newly developed programmable resistor. Resistors can be used to make up analog neural networks in artificial intelligence systems, based on a structure designed to mimic

The world’s biggest ice sheet could cause “several meters” of sea-level rise over centuries if the global temperature rises more than 2 °C, according to a British study published Wednesday. Researchers at Durham University concluded that if global greenhouse emissions remain high, the melting East Antarctica Ice Sheet (EAIS) could cause nearly half a meter

In a fascinating discovery, western lowland gorillas (Gorilla gorilla gorilla) at Zoo Atlanta have been caught summoning their keepers using a strange cough-sneeze hybrid. Only two other species have displayed this ability to create new vocalizations to attract our attention: zoo-housed chimpanzees and orangutans. Now, we can add gorillas to that list. Below, 24-year-old female

Within 24 hours of accessing the first stage of Australia’s newest supercomputing system, researchers have processed a series of radio telescope observations, including a highly detailed image of a supernova remnant. The very high data rates and the enormous data volumes from new-generation radio telescopes such as ASKAP (Australian Square Kilometre Array Pathfinder) need highly

Is there a “fourth phase of water”? From time to time you might see people talking up the health benefits of so-called hexagonal water, or structured water, or exclusion-zone (EZ) water. A few weeks ago Kourtney Kardashian’s Poosh website was spruiking a US$2,500 “structured water filter”. Last weekend even Australia’s Sydney Morning Herald got in

Bacterial colonies would rather perform “evolutionary suicide“ than put up with cheater strains that leech off the colony without giving anything back.  That’s the finding made by a team of researchers who modeled how a colony responds to freeloading bacteria that consume more than their fair share. Bacteria often work together as a colony to survive, producing resources that

Mysterious large pieces of wreckage were discovered across Southeast Asia over the weekend, and evidence is growing that they came from a Chinese rocket booster that fell to Earth uncontrolled. The booster of China’s 25-ton Long March 5B rocket pushed a new segment of the country’s space station into orbit in late July. Then, instead of pushing itself

A bizarre seafloor creature covered with luminous orange, spaghetti-like tentacles recently made its internet debut in newly released video footage. The unusual pom-pom-shaped creature is actually a type of segmented marine worm known as a polychaete, and it belongs to an appropriately named group: spaghetti worms.  Researchers from the Monterey Bay Aquarium Research Institute (MBARI)

As antibiotic-resistant bacteria become increasingly challenging to defeat, consulting those who’ve been in battle with our ancient foe long before us just makes a whole lot of sense.  Viruses called bacteriophages have been clashing with bacteria since long before we even existed. So researchers from the University of California, San Diego, took a closer look

Physicists have just caught light acting the part of ‘glue’ between atoms, in a kind of loosely bonded molecule. “We have succeeded for the first time in polarizing several atoms together in a controlled way, creating a measurable attractive force between them,” says University of Innsbruck physicist Matthias Sonnleitner. Atoms connect to form molecules in a

The discovery of multiple exoplanets that appear to be shrinking appears to resolve a ‘missing link’ in planetary evolution. Four mini-Neptunes in close proximity to their stars have been found leaking their atmospheres at a rate consistent with eventual total loss. This suggests that these worlds will eventually shrink into terrestrial, roughly Earth-sized planets –
