A study showed that -- within an appropriate framework -- gait recognition could be a viable technique for protecting individuals and their data from potential crime.

Referred to as 'China's Venice of the Stone Age', the Liangzhu excavation site in eastern China is considered one of the most significant testimonies of early Chinese advanced civilization. More than 5000 years ago, the city already had an elaborate water management system. Until now, it has been controversial what led to the sudden collapse. Massive flooding triggered by anomalously intense monsoon rains caused the collapse, as geologists and climate researchers have now shown.

Researchers have developed a method for incorporating security in the physical nature of the wireless transmission signal for 5G and future networks.

Researchers have now reconstructed how the Indian summer monsoon responded to meltwater pulses into the North Atlantic at the end of the penultimate cold period.

The largest survey of pollinator abundance in Wales has found that woodland and hedgerow creation can play a crucial role in action to reverse declines in insects that are essential for crop yield and other wildlife.

Climate scientists identify abrupt transitions in climate records that may have been caused by the climate system crossing a tipping point. They devised a statistical method to determine whether these transitions are simply noise or evidence of a more significant change. Their method is less error-prone than previous methods, since it doesn't rely on human determination. It also allows comparing different records consistently and can identify important events that may have been overlooked in older studies.

Researchers have used a nanoantenna to focus light onto a single semiconductor nanobox. This approach will enhance the utility of quantum repeater technology currently under development for advanced communication and data storage. Such technology is essential to overcoming the limitations of classical computer information for securely sharing information over long distances.

Computer scientists have discovered an inexpensive way for tech companies to implement a rigorous form of personal data privacy when using or sharing large databases for machine learning.

Scientists have built a plant that can produce carbon-neutral liquid fuels from sunlight and air. The next goal will be to take this technology to industrial scale and achieve competitiveness. Researchers now describe how this novel solar reactor functions and outline a policy framework that would provide incentives to expand the production of 'solar kerosene'.

To counter hacking, researchers have developed a new system based on the concept of 'zero-knowledge proofs', the security of which is based on the physical principle of relativity: information cannot travel faster than the speed of light. Thus, one of the fundamental principles of modern physics allows for secure data transfer.

Heat from a comet exploding just above the ground fused the sandy soil into patches of glass stretching 75 kilometers, a new study found.

Precambrian cratons -- some of Earth's oldest rocks -- were uninhabitable for microbes for much of their existence, with the longest period of habitability not much beyond a billion years, and many only for the past 50 million to 300 million years, according to a paper correlating Earth's deep biosphere with geologic history.

Scientists have used down-scaled laboratory models to show how sand dunes move through a landscape, revealing the conditions that determine whether they will pass through hurdles in their path -- like pipelines or walls -- or get stopped in their tracks.

Water is a scarce commodity in many countries worldwide, but new cost-effective technology pioneered by researchers in Australia, Egypt and Saudi Arabia could ensure sustainable water supplies for decades to come.

Climate 'tipping points' can be better understood and predicted using climate change data taken from the ancient past, new research shows.

Physicists have described in theoretical terms how to develop codes that cannot be broken by quantum computers -- computing devices of the future. These codes rely on distributing single photons that share a quantum character solely among the parties that wish to communicate.

Plants need water to grow. So if there's water, shouldn't there be more plants? New research shows it's a lot more complicated than that.

SUTD has set out to apply concepts from quantum Parrondo's paradox in search of a working protocol for semiclassical encryption.

Hot desert sex has resulted in major genetic differences between male and female jojoba plants -- one of only 6 percent of plants that require a male and female plant to reproduce. New research suggests male and female jojoba plants have diverged so much, that the jojoba plant has more novel sex genes than any other known living organism. The discovery may help researchers develop a DNA test to identify male and female jojoba plants, which cannot be distinguished from each other as seedlings - and shed light on how plants adapt to environmental stress.

The landscape at Lava Beds National Monument in northern California is typically home to sage and junipers, with unique lava caves twisting underneath the surface. But in the summers of 2020 and 2021, wildfires tore through the region, burning thousands of acres and leaving the surface charred.
