Exposing liars by distraction

It is well documented that lying during interviews takes up more cognitive energy than telling the truth. A new study found that investigators who used this finding to their advantage by asking a suspect to carry out an additional, secondary, task while being questioned were more likely to expose lie tellers. The extra brain power needed to concentrate on a secondary task (other than lying) was...
What makes some creatures more afraid of change than others?
Humans are undoubtedly altering the natural environment. But how wild animals respond to these changes is complex and unclear. In a new study published today, scientists have discovered significant differences in how the brain works in two distinct personality types: those who act fearless and those who seem afraid of new things. Being fearless can help wildlife, specifically birds, find new food...
Computational sleuthing confirms first 3D quantum spin liquid
Computational detective work by U.S. and German physicists has confirmed that cerium zirconium pyrochlore is a 3D quantum spin liquid.
Study points to ways of involving visually impaired people in environmental disaster prevention
According to the latest report of the Intergovernmental Panel on Climate Change (IPCC), almost half the world's population—about 3.3 billion to 3.6 billion people—live in contexts that are highly vulnerable to the impact of climate change. Social inequality greatly increases this vulnerability.
Exploring how deficits can be avoided at major sporting events
The World Cycling Championships in Bergen in 2017 had budgeted slightly more than €16.5 million in both revenues and costs. They missed the mark on both counts, and the event incurred a € 5.8 million deficit.
Wildlife: What makes some animals more afraid of change than others?

Humans are undoubtedly altering the natural environment. But how wild animals respond to these changes is complex and unclear. Scientists have now discovered significant differences in how the brain works in two distinct personality types: those who act fearless and those who seem afraid of new things. Being fearless can help wildlife, specifically birds, find new food sources, explore new nesting...
There are reasons girls don't study physics, and they don't include not liking math
"From my own knowledge of these things, physics is not something that girls tend to fancy. They don't want to do it … There's a lot of hard math in there that I think that they would rather not do," Katharine Birbalsingh, chair of the U.K. government's Social Mobility Commission and a secondary school head teacher, told the Commons Science and Technology Committee on April 27 2022.
The role of changing dietary habits in mitigating global warming
When we think of tools to achieve climate goals such as limiting the average temperature increase to 1.5 degrees above that of the pre-industrial age, most of us visualize wind turbines, solar panels and electric cars. Even the climate policy models currently in use, the so-called Integrated Assessment Models (IAMs), which aim to borrow and combine insights from climate science, engineering, and...
How microplastics in the air are polluting the most remote places on Earth
Microplastics are being transported to some of the most remote places on Earth by the wind, according to new research involving the University of East Anglia. A new study published today in Nature Reviews Earth & Environment shows how wind transports these particles great distances, and much faster than water can.
Study provides new insights into steelmaking off-gas treatment
Both catalytic combustion (CC) and chemical looping combustion (CLC) are promising technologies for energy saving and emission reduction of CO2 in treatment of steelmaking off-gas (CO).
Sinhcaf-dependent histone deacetylation essential for primordial germ cell specification
Primordial germ cells (PGCs) are the first germ-cell population established during development. The survival of species is dependent upon PGCs in sexually reproducing organisms because they are the founder cells for the germline.
Scientists show reduced heavy metal toxicity in goldfish using hard water
When industrial effluents containing high levels of heavy metals are discharged into fish bodies, they pose a serious threat to aquatic ecosystems. One such heavy metal, zinc, is required by organisms in miniscule amounts, but if it accumulates in higher concentrations, zinc can trigger oxidative stress in the fish body. This causes metabolic, physiological, and cellular damage, including protein...
New bill aims to limit frenzy of well drilling on California farms
In farming areas across Calfornia's Central Valley, a well-drilling frenzy has accelerated over the last year as growers turn to pumping more groundwater during the drought, even as falling water levels leave hundreds of nearby homes with dry wells.
New report highlights issues surrounding the future of the care economy.
As society continues to emerge from COVID-19 into a recovery economy, questions about the future of care also emerge. In Canada, the pandemic revealed existing problems with the care economy such as the poor conditions in long-term care homes and the dearth of affordable and high-quality early childhood education as well as the low pay and poor working care workers face on a daily basis.
Photosynthesis unaffected by increasing carbon dioxide channels in plant membranes
Modifying photosynthesis has increasingly been a research target to improve crop yields to feed a growing global population in the face of climate change and other environmental factors. In a recent study, published in the Journal of Experimental Botany, a team from the Australian National University (ANU) investigated the effects of increasing the number of carbon dioxide channels in plant...
Researchers use light for thermomagnetic recording on silicon waveguide
Researchers have demonstrated, for the first time, light-induced thermomagnetic recording in a magnetic thin-film on silicon waveguides. The new writing technique is poised to enable miniature high-performance magneto-optical memories that don't require bulky optics or mechanical rotation.
Study finds cells take out the trash before they divide
MIT researchers have discovered that before cells start to divide, they do a little cleanup, tossing out molecules that they appear not to need anymore.
Bali-like temperatures in Wyoming? Fossils reveal tropically hot North America 95 million years ago
A new University of Michigan study that used fossil oyster shells as paleothermometers found the shallow sea that covered much of western North America 95 million years ago was as warm as today's tropics.
Engineers develop fast and accurate COVID-19 sensor
Engineers at Johns Hopkins University, supported in part by the U.S. National Science Foundation, have developed a COVID-19 sensor that addresses the limitations of the two most widely used types of COVID-19 tests: PCR tests that require sample preparation, and the less accurate rapid antigen tests.

Researchers have discovered that before cells start to divide, they toss waste products. Using a new method they developed for measuring the dry mass of cells, the researchers found cells suddenly lose mass as they enter cell division.
Scientists advance renewable hydrogen production method

Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to a recent analysis. Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and for other industrial applications.
