Plants convert light into a form of energy that they can use—a molecule called adenosine triphosphate (ATP)—through photosynthesis. This is a complex process that also produces sugar, which the plant can use for energy later, and oxygen. Some bacteria that live in the light-exposed layers of water sources can also convert light to ATP, but the process they use is simpler and less efficient...
Pollution of the soil and water with multiple heavy metals is a common problem. However, most studies on the effects of heavy metals on bacteria living in these environments have only focused on one metal at a time. In a recent study, researchers found that exposing bacteria to a mixture of metals caused their metabolism to change. The researchers did not observe this change when bacteria grew...
Are people who earn more money happier in daily life? Though it seems like a straightforward question, research had previously returned contradictory findings, leaving uncertainty about its answer.
New Curtin research has found the spike proteins of SARS-CoV-2, a strain of coronaviruses that caused the COVID-19 pandemic, become trapped when they come into contact with silicon, gold and copper, and that electric fields can be used to destroy the spike proteins, likely killing the virus.
Researchers have developed an algorithm that uses computer vision techniques to accurately measure trees almost five times faster than traditional, manual methods.
Rice, a major food crop, is cultivated on nearly 162 million hectares of land worldwide. One of the most commonly used methods to quantify rice production is rice plant counting. This technique is used to estimate yield, diagnose growth, and assess losses in paddy fields. Most rice counting processes across the world are still carried out manually. However, this is extremely tedious, laborious,...
A team of researchers at NYU Abu Dhabi has developed a single-step, organic solvent-free, hydrothermal process to convert polyethylene-based plastic bags and polypropylene-based surgical masks into carbon dots.
Most people value honesty while also recognizing that it is sometimes beneficial to be dishonest. This tension leads individuals to engage in behaviors that stretch the boundaries of honest behavior, such as strategically avoiding information, dodging questions, and making misleading statements. In a new article, researchers reviewed work from a range of disciplines to develop a framework that...
Genetic variations, such as mutations, recombinations, or transpositions occur naturally in cultured microorganisms and are often considered nonneutral mutations.
Scientists have uncovered a chemical compound that holds potential as a therapeutical for various autoimmune diseases, and they've used it to treat mice.
Reconciling previously contradictory results, researchers find that for most people, there's a steady link between higher happiness and more money. The exception is people who are financially well-off but unhappy; for them, more money does not help.
The Big Bang may have not been alone. The appearance of all the particles and radiation in the universe may have been joined by another Big Bang that flooded our universe with dark matter particles. And we may be able to detect it.
Our universe may feature large, macroscopic clumps of dark matter known as q-balls. These q-balls would be absolutely invisible, but they may reveal their presence through tiny magnifications of starlight.
A model for predicting the levels of oxygen in water, developed by West Virginia University researcher Omar Abdul-Aziz, gives citizen scientists nationwide a tool for taking action on stream pollution.
Researchers developed an educational game that uses augmented reality and tangible interaction to teach STEM to young students. They recently revealed their research findings on the usage and efficiency of the game to promote the learning of chemistry and improve children's perception towards the subject.
India's drastic COVID-19 lockdowns had a silver lining. With polluting industries and vehicular movement halted, urban dwellers were treated to bright, blue skies and views of snow-clad Himalayan peaks, long obscured by thick smog.
Over the last decade, parents have become increasingly aware of the importance of a child's physical and mental development in their early years. As a result, there has been a significant rise in parents' demand for evidence-based knowledge of child-rearing.
A Rutgers-led team of scientists studying virus-host interactions of a globally abundant, armor-plated marine algae, Emiliania huxleyi, has found that the circular, chalk plates the algae produce can act as catalysts for viral infection, which has vast consequences for trillions of microscopic oceanic creatures and the global carbon cycle.
Tropical storm Freddy returned to Madagascar in what meteorologists described on Monday as a "rare" loop trajectory, killing four people, including two children as it hit for the second time in as many weeks.
Protecting life in the vast expanse of ocean beyond national jurisdictions finally has an international roadmap after UN states agreed a landmark high seas treaty at the weekend.
Researchers in Japan have developed a new method for purifying cholesterol-modified DNA nanostructures that could be used to functionalize molecular robot bodies (lipid vesicles). The study was a collaboration between Yusuke Sato of Kyushu Institute of Technology and Shin-ichiro M. Nomura of the Tohoku University, and the work was published in ChemBioChem.
Conifers are generally better than broadleaved trees at purifying air from pollutants. But deciduous tree may be better at capturing particle-bound pollution. A new study led by the University of Gothenburg shows that the best trees for air purification depend on the type of pollutant involved.
The environment is in crisis. Young people are calling for environmental action and requesting more education about the environment and the climate emergency. They are also looking at what they can do to tackle climate change.
Habitat destruction, pesticide use, and other human impacts are often blamed for the well-documented decline of insects in recent decades. But even in forests where few humans tread, some bees and butterflies are declining, researchers have found. Over the past 15 years, populations of bees shrank 62.5% and those of butterflies dropped 57.6% in a forest in the U.S....

Warmer and drier climate conditions in western U.S. forests are making it less likely that trees can regenerate after wildfires, according to new research published in the Proceedings of the National Academy of Sciences.
The DNA sequence of a gene in wheat responsible for resisting a devastating virus has been discovered, providing vital clues for managing more resistant crops and maintaining a healthy food supply.
Infrared spectroscopy is a noninvasive tool used to identify unknown samples and known chemical substances. It is based on how different molecules interact with infrared light. You may have seen this tool at airports, where they screen for illicit drugs. The technique has many applications: liquid biopsy, environmental gas monitoring, contaminant detection, forensic analyses, exoplanet searches,...
My colleague, mentor and friend Heidy Mader, who has died aged 61 of cancer, was an outstanding experimental scientist. She applied lessons learned in developing the Wispa chocolate bar as a research physicist at Cadbury to lead a revolution in understanding the flow of lava and magma as a professor at Bristol University.Heidy was born in Cosford, Shropshire, to Renate (nee Pitz) and Eric Mader....
The Rosetta Stone is not known for its content, but as a lexicon of Egyptian hieroglyphics. The decree inscribed on the stone, however, discusses a violent revolt—largely lost to history—that shaped the trajectory of western civilization.
The first global study to investigate how gender equality may be associated with life expectancy has found that both women and men live longer as it improves.

CTE is a progressive neurodegenerative disease frequently found in contact sports athletes. However, many former contact sports athletes suffer from thinking problems and impulsive behavior in the absence of CTE, or with very mild CTE. This new study suggests that a separate type of brain damage, which can appear earlier than CTE, may underlie some of these symptoms.
New methodology and tools provide an opportunity to watch in unprecedented detail as a phage attacks a bacterium.
Adding to the growing body of evidence on sleep disturbances and cognitive impairment, new research finds significant links between three measures of sleep disturbance and the risk for developing dementia over a 10-year period. The results associate sleep-initiation insomnia (trouble falling asleep within 30 minutes) and sleep medication use with higher risk for developing dementia. The...
Hair analysis could be the key to understanding adolescent drug usage, as a new study uncovers almost double the number of children were found to be using substances than those who admitted to in a US survey.
A new study shows what it will take for the plastics industry to become completely sustainable: lots of recycling combined with the use of CO2 from the air and biomass. It is also the image of plastics that need to change.
Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study.
