Disputes over fairness can create conflict. Families squabble over inheritances, societies polarize around the question of how to distribute wealth fairly, and nations become mired in territorial quarrels.
In dark skies around the world there unfolds a nightly battle between bats and the nocturnal insects upon which they feast. You'd have thought bats, equipped as they are with echolocation, in which they navigate using sound, would have no trouble gobbling up the apparently clueless insects you see banging against your windows after dusk.
3D printing is revolutionizing manufacturing by wasting much less material and energy than that by conventional machining and production line assembly. Now, researchers from Japan have made a discovery that will help companies reliably make even highly complex 3D-printed products.
The Antarctic ice sheet is the largest mass of ice in the world, holding around 60% of the world's fresh water. If it all melted, global average sea levels would rise by 58 meters. But scientists are grappling with exactly how global warming will affect this great ice sheet.
An internal Facebook report found that the social media platform's algorithms—the rules its computers follow in deciding the content that you see—enabled disinformation campaigns based in Eastern Europe to reach nearly half of all Americans in the run-up to the 2020 presidential election, according to a report in Technology Review.

Researchers present a unique optical amplifier that is expected to revolutionize both space and fiber communication. The new amplifier offers high performance, is compact enough to integrate into a chip just millimeters in size, and -- crucially -- does not generate excess noise.
A study of semi-captive Asian elephants in Myanmar has found that calves benefit from having older sisters more than older brothers.
Researchers have found a way to make what is called reservoir computing work between 33 and a million times faster, with significantly fewer computing resources and less data input needed.
Researchers have created an artificial intelligence tool that reduces the time and effort required to discover truly new materials, and has already led to the discovery of four new materials.
Scientists have developed processed red meat that includes added natural substitutes which reduces the carcinogenic compound nitrite added to preserve meats. The range of sausages and hams had a mixture of plants and fruits added to them which included rosemary, green tea, and resveratrol -- an extract taken from Japanese Knotweed.
Self-amplifying mRNA jab aims to trigger immune response towards virus’s spike and non-spike proteinsCoronavirus – latest updatesSee all our coronavirus coverageThe first trials have begun of a Covid booster jab that it is hoped will offer good protection against a wide range of variants, researchers have revealed.Covid jabs currently used in the UK trigger an immune response towards the...
In Germany, flying insects have declined by 76% in 26 years. In the UK, common butterfly populations have fallen by 46% since 1976. We should be alarmed by this insect apocalypseInsects have been around for more than 400m years, their ancestors crawling from the oceans to colonise the land long before dinosaurs appeared. They have been enormously successful, evolving into a staggering diversity of...
Researchers at the University of Liverpool have shown how SARS-CoV-2 viral proteases attack the host cell, and how this can be targeted to stop virus replication in cell culture using existing drugs.
A relatively new type of computing that mimics the way the human brain works was already transforming how scientists could tackle some of the most difficult information processing problems.
Researchers at the University of Liverpool have created a collaborative artificial intelligence tool that reduces the time and effort required to discover truly new materials.
The food and drink industry is warning of supermarket shortages because of a lack of CO2.
A wildfire broke out in a Greek seaside town northeast of Athens on Monday, burning through brush and pine trees and causing precautionary evacuations, firefighters said.
NASA on Monday announced it would land an ice-seeking rover on a region of the Moon's south pole called the Nobile Crater in 2023.
Hundreds of firefighters were battling to protect several groves of giant sequoias in the United States on Monday, warning the enormous ancient trees were at risk from out-of-control blazes.
In the bay of Vlora on central Albania's coast, crystal clear waters sparkle in the sun but under the surface, it is a desert.
