Researchers suggest novel way to generate a light source made from entangled photons

Credit: Pixabay/CC0 Public Domain Entanglement is a strange phenomenon in quantum physics where two particles are inherently connected to each other no matter the distance between them. When one is measured, the other measurement is instantly a given. Researchers from Purdue University have proposed a novel, unconventional approach to generate a special light source made … Read more

New approach more than doubles stem cell editing efficiency, researchers report

A Penn State student measures modified RNA concentration with a spectrophotometer. The researchers found that modified RNA improves the efficiency of CRISPR-Cas9 delivery. Credit: Kate Myers/Penn State A Penn State-led team of interdisciplinary researchers has developed techniques to improve the efficiency of CRISPR-Cas9, the genome editing technique that earned the Nobel Prize in 2020. While … Read more

Researchers identify a potential path against inherited neurological disease

Researchers at the Icahn School of Medicine at Mount Sinai and NCATS identified compounds that reversed the effects of several neurodegenerative diseases called lysosomal storage disorders (LSDs) in patient cells and mice. LSDs are characterized by genetic defects that prevent the cell’s lysosomes from breaking down and recycling fats, sugars and proteins, which can accumulate … Read more

Researchers quantify the amount of energy that plants use to lift water on a global scale

A stand of quaking aspens pump water up to their canopies in southwestern Colorado. Credit: Leander Anderegg Every day, about one quadrillion gallons of water are silently pumped from the ground to the treetops. Earth’s plant life accomplishes this staggering feat using only sunlight. It takes energy to lift all this liquid, but just how … Read more

Researchers working to reduce space junk threat, impact

New research points to increasing pollution in the upper atmosphere due to reentering satellites, rocket bodies and other incoming spaceflight flotsam. That troublesome trend is leading researchers to come up with mitigation proposals, one of which would use fabrication concepts to reduce the size of space debris pieces that make it to Earth. The Aerospace … Read more
