Osmotic power plants harvest energy from the difference in pressure or salinity between salt and freshwater using a semi-permeable membrane. One of the major challenges for this kind of renewable energy, however, has been developing effective and durable membranes. Now, new research demonstrates a durable and effective membrane that could significantly improve osmotic energy collection. None By n
Life as we know it requires phosphorus, and lots of it. But phosphorus is scarce. A new study reports that certain types of carbonate-rich lakes, which could have formed on early Earth, have the right chemistry to keep phosphorous levels high and available to organisms.
The sea encircling Antarctica mixes water from all the ocean basins. This circulating pattern influences the exchange of carbon dioxide (CO2) between the ocean and the atmosphere. A study by an international research team, led by Dr. Torben Struve from the University of Oldenburg, Germany, indicates that the complex equilibrium of water masses reacts sensitively to wind conditions over the Souther
It's pretty easy to stay tipsy, as long as you're mindful (Alasdair Elmes/) The holidays are upon us and just as we surround ourselves with loved ones, we'll probably find ourselves likewise surrounded by a sea of booze. Whether that's rum-spiked cider, pricey wines, or fancy cocktails we'd normally never have time to make, the holiday atmosphere and delectable offerings can certainly make it tem
Direct-to-consumer hormone-based 'fertility testing' for women is viewed by consumers as both an alternative, empowering tool for family planning, and a confusing and misleading one, according to the results of a new study from Penn Medicine.
The theoretical notion of a 'quantum heat engine' has been around for several decades. It was first introduced around sixty years ago by Scovil and Schulz-DuBois, two physicists at Bell Labs who drew an analogy between three-level masers and thermal machines.
It's Friday, December 27. In today's issue: Memorable shows; memorable films; memorable TV moments (yes, a Game of Thrones scene made the cut). The year is coming to a close, and you know what that means: It's time for best-of-the-year lists. We're spending the remaining days of 2019 rounding up some of our editors' and writers' favorite things to watch, read, and listen to from this past year. T
Researchers across the globe are already working on ways to destroy or at least redirect any killer asteroids before they slam into the Earth. But what if scientists discover that Earth is threatened by an entire asteroid shower? Or that some other cosmic phenomenon, such as nearby star going supernova, is on track to destroy the planet? In those instances, our survival might depend not on stoppi
Neurosexism, past and present Science has been used as a tool of women's oppression at least since Darwin formulated his theory of natural selection. In addition to On the Origin of Species , Darwin wrote a volume entitled The Descent of Man, and Selection in Relation to Sex , a book that attempted to explain observable differences between men and women in evolutionary terms. According to Darwin,
The spread of new electronic pills with built-in sensors creates both ethical and legal challenges, researchers warn. The new electronic pills can collect data, for example, on the state of the stomach and intestines, and this creates new opportunities for diagnosing diseases. The pills can also be used to monitor medication (e.g., in patients with mental disorders). Pills with built-in sensors a
The American coot is a somewhat drab water bird with gray and black feathers and a white beak, common in wetlands throughout North America. Coot chicks, however, sport outrageously bright orange and red feathers, skin, and beaks. A new study explains how the bright coloring of coot chicks fits in with the reproductive strategy of their less colorful parents.

Computational modeling is offering clues about how some tree roots, like those of pines and junipers, may respond to drought in light of a warming world. The new research addresses a classic question in the field: When conditions are dry for long periods of time, do trees grow new roots to tap water sources to survive or rely on established roots that already go deep? The answer, at least for som
A population of neurons in the brain's frontal lobe contains stable short-term memory information despite dynamically-changing neural activity, researchers report.

There may be a way to know when cancer-prone cells will turn into full-blown cancer, researchers report. It may become possible for biomarkers in blood to reveal whether mutated cells have turned a corner toward forming tumors, and how long the process—depending on the type of cancer—is likely to take. That could give patients a sense of the risk they face before they become ill. The researchers
To extract nectar from flowers dancing in the wind, moths depend on precise, millisecond timing between their brain and muscles, researchers report. Researchers captured and analyzed nearly all of the brain signals sent to the wing muscles of hawk moths ( Manduca sexta ), which feed on such nectar, to show that precise timing within rapid sequences of neural signal spikes is essential to controll

One of the wonders of cell biology is its symmetry. Mammalian cells have one nucleus and one cell membrane, and most humans have 23 pairs of chromosomes. Trillions of mammalian cells achieve this uniformity—but some consistently break this mold to fulfill unique functions.

New research reveals the counterintuitive tweaks to the chemistry of a solar cell material that have boosted its power output. A solar energy material that's remarkably durable and affordable is also regrettably unusable if it barely generates electricity, so many researchers had abandoned emerging organic solar technologies.

The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate.

On Monday, Chinese state-run news agency Xinhua reported that He Jiankui, the researcher responsible for creating the world's first gene-edited babies, had been sentenced to three years in prison on the charge of illegally practicing medicine. Given that China condemned He's research almost immediately after he announced the births of the twin babies, it's not particularly surprising to hear that

Two-dimensional solar materials may offer a way to extract more energy from sunlight. By tuning the structure of a 2-D perovskite solar material, researchers from KAUST and the Georgia Institute of Technology have shown they can prolong the lifetime of highly energetic hot carriers generated by light striking the material. The approach could offer a way to capture solar energy more efficiently.

Until recently, Stemphylium leaf blight has been considered a minor foliar disease as it has not done much damage in New York since the early 1990s. However, onion growers in New York have recently seen an increase in the dieback of their crops, and scientists at Cornell University were surprised to discover that SLB was the cause.
As the world warms, a new study is helping scientists understand how coniferous forests may respond to drought.
