Researchers have devised an ingenious method of using acoustics to conceal and simulate objects.

Previous fires may hold the key to predicting and reducing the severity of future wildfires in the western United States as fire activity continues to increase, according to researchers.

Scientists reveal new approaches to manipulating light absorption in optical resonators by different types of optical losses.

The effects of monsoon rainfall on food insecurity in Nepal vary by earthquake exposure, with regions that experienced both heavy earthquake shaking and abundant rainfall more likely to have an inadequate supply of nutritious food, according to new research.

A team of researchers is using a novel technique to comb through the data and to reconstruct major branches in the linguistic tree.

A decades-long study of introduced voles on the Norwegian islands of Svalbard is helping to answer a longstanding puzzle of Arctic ecology -- what drives the well-established population cycles of small Arctic mammals, such as voles and lemmings. These plant-eating rodents are among the most populous Arctic mammals. The results suggest the importance of predators as a primary factor driving the...

A new study into cognitive control promises to be the first of many aimed at understanding its origins in the brain and its variations between people and among groups.

CD8+ T cells -- known as "killer" T cells -- are the assassins of the immune system. Once they are primed, they seek out and destroy other cells that are infected with virus or cells that are cancerous. Priming involves dendritic cells -- sentinels of the immune system. In an influenza infection in the lungs, for example, lung-migratory dendritic cells capture a piece of the viral antigen, and...

A new silicon chip can decode any error-correcting code through the use of a novel algorithm known as Guessing Random Additive Noise Decoding (GRAND).

Researchers claim that previous calculations of ICT's share of global greenhouse emissions, estimated at 1.8-2.8%, likely fall short of the sector's real climate impact as they only show a partial picture. The researchers point out that some of these prior estimates do not account for the full life-cycle and supply chain of ICT products and infrastructure -- such as: the energy expended in...

Researchers find that machine-learning algorithms can identify effective behavioral, educational, and psychological interventions more accurately than professionals can.

Humans acknowledge that personality goes a long way, at least for our species. But scientists have been more hesitant to ascribe personality to other animals. A study has now documented personality in golden-mantled ground squirrels, which are common across the western U.S. and Canada.

A new conducted in both mice and a small group of patients with advanced cancers has shown that so-called 'cold' tumors that are nearly devoid of immune cells -- and therefore unresponsive to immunotherapy -- can be turned 'hot' with extremely low doses of radiation and the rational use of existing therapies.

School-aged children who spend more time in front of screens are only slightly more likely to have attention disorders, disturbed sleep or lower grades and are no more likely to suffer from depression and anxiety. Meanwhile, they tend to have more close friends.

Large carnivore populations are expanding across Europe and experts are calling for increased support for communities to encourage harmonious relationships with their new neighbors.

The increasing use of photoinitiators, especially in medical settings, has raised concerns about their adverse effects on human health. Now, scientists have shown that three photoinitiators -- 1-HCHPK, MBB, and MTMP -- show estrogen-like activity in mice and increase the growth of breast cancer tumors in these animals. Their results warn against the use of such chemicals in medical instruments...

An international team of researchers developed the largest and most detailed simulation of the Universe to date and has made it freely available on the cloud to everyone. This simulation, named Uchuu, will help astronomers to interpret results from Big Data galaxy surveys.

Scientists report a vampire fish attached to the body of an Amazonian thorny catfish. Very unusually, the candirus were attached close to the lateral bone plates, rather than the gills, where they are normally found. Since the hosts were not badly harmed, and the candirus apparently derived no food benefit, scientists believe this association is commensalistic rather than parasitic.

Researchers have imaged the atoms at the surface of the light-absorbing layer in a new type of next-generation solar cells, made from a crystal material called metal-halide perovskite. Their findings have solved a long-standing mystery in the field of solar power technology, showing how power-boosting and stability-enhancing chlorine is incorporated into the perovskite material.

Scientists have identified metabolic compounds within the blood that are associated with dementia. The study revealed that the levels of 33 metabolites differed in patients with dementia, compared to elderly people with no existing health conditions. Their findings could one day aid diagnosis and treatment of dementia.

Differences between gut flora and genes from konzo-prone regions of the Democratic Republic of Congo (DRC) may affect the release of cyanide after poorly processed cassava is consumed, according to a study with 180 children. Cassava is a food security crop for over half a billion people in the developing world. Children living in high-risk konzo areas have high glucosidase (linamarase) microbes...

Using CRISPR, scientists have created a new technology for controlling mosquitoes. The precision-guided sterile insect technique alters genes linked to male fertility and female flight in Aedes aegypti, the species responsible for spreading diseases including dengue fever, chikungunya and Zika.

An international research team with participation of the Paul Scherrer Institute PSI has revealed a secret about a marine animal's shell: The researchers have deciphered why the protective cover of the brachiopod Discinisca tenuis becomes extremely soft in water and gets hard again in the air. The study appears today in the journal Nature Communications.

Simply by adding sugar, researchers have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.
