Genomic test could help stop destructive Asian spongy moth in its tracks‎

Invasive species cost Canada billions of dollars each year. Now, a team led by UBC researchers has developed a new genomic test that can trace the Asian spongy moth—one of the biggest threats to North America's forests—back to its source, giving officials a better chance of stopping infestations before they spread. The findings are published in the journal BMC Genomics.

Why Americans think they won't benefit from Social Security‎

Social Security's trust funds are projected to run out by 2035, but that doesn't mean retirees will be left with nothing. New research from the Cornell SC Johnson College of Business reveals that most Americans misinterpret what happens when the funds reach zero, and the way information is presented plays a significant role in this confusion.

'Gray-box' AI reveals why catalysts work while speeding discovery‎

Self-driving laboratories (SDLs) powered by artificial intelligence (AI) are rapidly accelerating materials discovery, but can they also explain their results? Researchers from the Theory Department of the Fritz Haber Institute, in collaboration with BASF, and BasCat—UniCat BASF JointLab, show that they can.

New NMR method allows the observation of chalcogen bonds‎

Toward the right side of the periodic table below oxygen, are the chalcogens, or "ore-forming" elements. The chalcogens that occur naturally, including sulfur, selenium and tellurium, are all somehow involved in biological processes. Molecules containing sulfur, like the antioxidant glutathione, play a central role in redox regulation, the balance between oxidation and reduction that is essential for maintaining cellular health.

Catalina Island study highlights open-coast seagrass restoration success‎

New research led by scientists at UC San Diego's Scripps Institution of Oceanography is shining a spotlight on one of the ocean's most overlooked habitats: seagrass. Led by Scripps Oceanography Ph.D. candidate Rilee Sanders, the study documented the first successful restoration of open-coast seagrass (common eelgrass). The findings offer promising insight into the feasibility of restoring high-value coastal habitats in the future. The work is published in the journal Estuaries and Coasts.

When shrubs disappear: Exploring long-lasting effects of drought in southwest China‎

Droughts are becoming both more frequent and more intense in many parts of the world. Savannas, which cover nearly 20% of Earth's land surface and play a key role in carbon, water and energy cycles, can therefore be severely affected when an exceptionally dry period strikes. Previous research has shown how savannas respond during drought. However, less is known about what happens afterward.

We are flushing paracetamol down the toilet and into our water supply: Here's how it could be removed‎

Many people use drugs, including paracetamol, on a regular basis to treat headaches. But only part of each drug is taken into the bloodstream, while the rest is released into the wastewater through our urine when we go to the toilet.

Electronics of the future: Ultra-efficient graphene switch developed at nanometer scale‎

A team of researchers from Tel Aviv University, in collaboration with colleagues from Japan, has taken an important step toward the next generation of electronics. The scientists achieved highly precise control of the internal structure of graphene—an exceptionally thin and strong material—using a minute, nearly negligible amount of energy.

600-year-old pinot noir grape found in medieval French toilet‎

A 600-year-old grape seed discovered in the toilets of a medieval French hospital is genetically identical to the grapes still being used to make pinot noir wine, scientists said Tuesday.

Why cooperative workplaces boost your sense of freedom‎

Jack Welch, the legendary General Electric CEO, was infamous for firing the bottom 10% of his workforce every year, without exception. The company's market cap rose substantially during Welch's tenure, but his "rank and yank" ritual was divisive. If you knew your job was always on the line, the logic went, you would push harder and generate results. Yet what did this approach do to the employees who had to constantly compete with each other to keep their jobs?
