Measuring marine biodiversity with "environmental DNA"—an application of gene sequencing to environmental biology—should permit rapid assessment of changes in marine life. That makes environmental DNA (eDNA) a critical tool for managing our response to climate change. But eDNA only works well if key implementation steps are followed, according to a new study of the Los Angeles and Long Beach...

There's a popular saying that people who ignore history are doomed to repeat it. It turns out that there's another reason not to ignore history, according to new research from Michigan State University published in the journal Ecology.

A paper published in Environmental Pollution, authored by Saint Louis University (SLU) scientists, shows that human proximity is the best indicator of microplastics being found in the Meramec River in Missouri.

Over 300 million people in Sub-Saharan Africa (SSA) depend on maize for nearly 30% of their caloric intake, and the popularity of maize is expected to continue its upward trend (IITA). As the demand for maize increases, so does the need for sustainable and safe production, yet numerous biotic and abiotic stressors threaten this staple crop in SSA.

Changing weather patterns have profound impacts on agricultural production around the world. Higher temperatures, severe drought, and other weather events may decrease output in some regions, but effects are often volatile and unpredictable. Yet many countries rely on agricultural and food trade to help alleviate the consequences of local, weather-induced production shifts, a new paper from the...

An estimated 80 percent of the world's cargo is transported via ship-borne containers—a method that has soared in use in the decades after World War II. The efficient, cost-effective method of packaging and moving goods across the world's oceans boomed with the globalization of trade, experiencing a near 20-fold increase in container tonnage in the past 40 years. An estimated 100 million tons...

Researchers have developed a high-performance, on-chip femtosecond pulse source using a time lens.

Researchers have revamped an anti-cancer drug to better target cancer cells and leave healthy tissues unharmed.

Researchers have discovered new waves with picometer-scale spatial variations of electromagnetic fields which can propagate in semiconductors like silicon.

Ecologists have shown that efforts to restore prairies can have vastly different outcomes in terms of their biodiversity and functionality when the only variable is the year a prairie is planted.

Scientists shows that human proximity is the best indicator of microplastics being found in the Meramec River in Missouri.

Environmental DNA left behind by ocean animals can be measured to inventory the marine life in a particular area.

People with neurologic diseases like headache, dementia, multiple sclerosis (MS) and Parkinson's disease may experience worsening symptoms due to climate change, according to a scoping review of research. The review also found that stroke may become more prevalent due to climate change.

People who have a COVID-19 infection are more likely to develop seizures or epilepsy within the next six months than people who have an influenza infection, according to a new study.

A study yields clues to why certain parts of the brain are particularly vulnerable to Alzheimer's damage. It comes down to the gene APOE, the greatest genetic risk factor for Alzheimer's disease. The parts of the brain where APOE is most active are the areas that sustain the most damage, they found.

Femtosecond pulsed lasers—which emit light in ultrafast bursts lasting a millionth of a billionth of a second—are powerful tools used in a range of applications from medicine and manufacturing, to sensing and precision measurements of space and time. Today, these lasers are typically expensive table-top systems, which limits their use in applications that have size and power consumption...

The number of U.S. adult handgun owners carrying a loaded handgun on their person doubled from 2015 to 2019, according to new research led by the University of Washington.

The Winchcombe meteorite, a rare carbonaceous meteorite which crashed onto a driveway in Gloucestershire in 2021, has been found to contain extra-terrestrial water and organic compounds that reveal insights into the origin of Earth's oceans.

Researchers at Purdue University have discovered new waves with picometer-scale spatial variations of electromagnetic fields that can propagate in semiconductors like silicon. The research team, led by Dr. Zubin Jacob, Elmore Associate Professor of Electrical and Computer Engineering and Department of Physics and Astronomy, published their findings in Physical Review Applied in a paper titled...

A new study led by Swansea University has shown how the flight of birds can offer a meteorological insight into fine scale environmental conditions.

A tide of plastic debris from all over the world has washed up on Ascension Island, says researchers.

Researchers at Forschungszentrum Jülich and the Berlin Institute of Health at Berlin's Charité Hospital have developed a novel method for determining the number of subunits within protein complexes. The method is a further development of "super-resolution" single molecule localization microscopy (SMLM), whose developers were awarded the Nobel Prize in Chemistry in 2014. The new technique allows...
