Virtually all wind turbines, which produce more than 5 percent of the world's electricity, are controlled as if they were individual, free-standing units. In fact, the vast majority are part of larger wind farm installations involving dozens or even hundreds of turbines, whose wakes can affect each other.

More than two decades of devastating drought worsened by man-made climate change mean California must harvest, recycle and desalinate much more water, the state's governor said Thursday.

Topology and entanglement are two powerful principles for characterizing the structure of complex quantum states. In a new paper in the journal Physical Review X, researchers from the University of Pennsylvania establish a relationship between the two.

Over-the-counter pain relievers, physical therapy, steroid injections—some people have tried it all and are still dealing with knee pain.

Genome editing can cure diseases, boost food production and open vast new fields of scientific discovery. But to realize its full potential, scientists need to precisely describe the details of their genome editing attempts to one another and the wider world.

With California enduring historic drought amplified by global warming, Gov. Gavin Newsom on Thursday released a new plan to adapt to the state's hotter, drier future by capturing and storing more water, recycling more wastewater and desalinating seawater and salty groundwater.

Millions of barrels of oil are produced daily from shale reservoirs, yet a significant amount remains untouched, trapped in molecular-sized pores on a nanoscale. Current reservoir models can't predict oil behavior or recovery at this scale, so companies can't accurately estimate production amounts for financial investors.

The arbuscular mycorrhizal symbiosis (AMS) is one of the most ancient and broadly occurring mutualistic associations between plants and arbuscular mycorrhizal fungi (AMF). This intimate relationship improves plant mineral nutrient acquisition, which potentially enhances crop yield. In addition, AMS can increase plant tolerance to biotic and abiotic stresses. AMS also contributes to many ecosystem functions, improving soil aggregation, lowering fertilizer requirements, and reducing nutrient losses.

A Northwestern University astrophysics team is aiming for the stars—well, a dead star, that is.

Bacteria use a variety of defense strategies to fight off viral infection, and some of these systems have led to groundbreaking technologies, such as CRISPR-based gene-editing. Scientists predict there are many more antiviral weapons yet to be found in the microbial world.

North Carolina State University researchers have demonstrated that a synthetic polymer can remove certain dyes from water, and that the polymer can be recovered and reused. The findings offer a new potential method for cleaning wastewater after use by textiles, cosmetics or other industries.

An ongoing debate among scientists, on why chimpanzees and other nonhuman primates cannot speak or sing like humans, has focused mainly on evolutionary changes in human brain development. Attention has now expanded to anatomical changes of the voice box that may have played a role in our capacity to produce complex sounds.

While Netflix is increasingly in the spotlight for its battle to retain subscribers, a QUT researcher says the streaming giant should not be compared to others and the notion of 'streaming wars' is out-dated.

From the 13th to the 16th of March 2021, an extremely strong dust storm struck Mongolia and northern China successively, causing 590 herdsmen to disappear and 16 people to die in Mongolia. When the dust storm reached central Inner Mongolia in the early morning of 15 March, the gust speed reached up to 40 m s−1, which is equivalent to the intensity of a grade 12 typhoon. When it arrived in the Beijing–Tianjin–Hebei region on the morning of 15 March, visibility decreased sharply and the concentration... Читать дальше...

Analyzing data from NASA's Hubble Space Telescope and several other observatories, astronomers have concluded that the bright red supergiant star Betelgeuse quite literally blew its top in 2019, losing a substantial part of its visible surface and producing a gigantic Surface Mass Ejection (SME). This is something never before seen in a normal star's behavior.

Idaho National Laboratory is perhaps best known for innovative research that helps shape the clean energy economies of today and tomorrow—and for good reason. But while much of the laboratory's work is focused on building a sustainable future, INL is also doing its part to preserve the past.

Knowledge about the spread of tick-borne diseases is extremely limited and notoriously difficult to acquire. A new study from the University of Copenhagen demonstrates that internet searches just might be the way to keep an eye on ticks and other effects of climate change.

A research team comprised of Woo Dae Jang, Gi Bae Kim, and Distinguished Professor Sang Yup Lee of the Department of Chemical and Biomolecular Engineering at KAIST reported an interactive metabolic map of bio-based chemicals. Their research paper "An interactive metabolic map of bio-based chemicals" was published online in Trends in Biotechnology on August 10, 2022.

Increasingly, global food production is being threatened by the effects of climate change. As floods, droughts, and extreme heat waves become more common, crops need to be able to adapt faster than ever.

Wood is infinitely useful. Critically important for our changing climate, trees store carbon. When trees are harvested for wood products like lumber, some of that carbon continues to be stored. Even after a wood product is discarded, it keeps storing carbon.

Insects are the world's smallest flying migrants, but they can maintain perfectly straight flight paths even in unfavorable wind conditions, according to a new study from the Max Planck Institute of Animal Behavior (MPI-AB) and the University of Konstanz. Researchers radio tracked migrating hawkmoths for up to 80 kilometers—the longest distance that any insect has been continuously monitored in the wild. By closely following individuals during migration, the world-first study unlocks a century-old... Читать дальше...

Chemist Jixin Chen looked at the rapid spread of COVID-19 early in the pandemic and saw a novel opportunity for his kinetics lab, where they study the rates of reactions.

North Carolina State University researchers released findings from an analysis of 284 different studies on the challenges and best practices for teaching K-12 classes online—an effort launched during the COVID-19 pandemic to help teachers and administrators as they transitioned rapidly to online instruction.

Wildfire has ravaged the Western United States throughout the last decade. Over three million acres have already burned across the country this year. As fires spark earlier and extend further into autumn each year, turning from "fire seasons" to "fire years," the National Interagency Fire Center reports that many Western U.S. regions show above-average fire potential.

Blue marlin (one of the largest fish) and sailfish (one of the fastest fish) provide some of the most prized fights in the sportfishing world, making catching them with rod and reel one of those "once in a lifetime" experiences. Their distinctive elongated front-end bill gives them a built-in sword-like weapon for hunting, and thus the moniker "billfish".
