A team of geochemists has found new evidence that Earth has been consistently churning out crust since its formation 4.5 billion years ago and that some crust is made of ancient, resurfaced chunks.
Will practice alone get you first chair in band? (Sharon McCutcheon/Unsplash/) In 1993, Swedish psychologist K. Anders Ericsson set out to find the secret to turning a typical teen into a violin virtuoso. His answer? Practice: 10,000 hours of it. The figure, a simple average of a few prodigies’ regimens, stuck; journalist and author Malcolm Gladwell even dubbed it “the magic number of greatness”

An international research team has developed a noninvasive technology platform for gene delivery into breast cancer cells. The technique combines ultrasound with tumor-targeted microbubbles.
In a new study of axion motion, researchers propose a scenario known as "kinetic misalignment" that greatly strengthens the case for axion/dark matter equivalence. The novel concept answers key questions related to the origins of dark matter and provides new avenues for ongoing detection efforts.
Progression of kidney disease in type 1 diabetes is correlated with increased amounts of uric acid. A drug that reduces uric acid levels was tested in a multi-institution randomized clinical trial. Though the study did not show the desired clinical benefit, it did provide a very clear answer to an important scientific question.
Dust storms from Africa's Saharan Desert traveling across the Atlantic Ocean are nothing new, but the current dust storm has been quite expansive and NASA satellites have provided a look at the massive June plume. NASA-NOAA's Suomi NPP satellite showed the blanket of dust had moved over the Gulf of Mexico and extended into Central America and over part of the eastern Pacific Ocean.
In the largest study of its kind, an association has been found in living patients exposed to repetitive head impacts and difficulties with cognitive functioning and depression years or decades later.

In biology, phylogenetic trees represent the evolutionary history and diversification of species — the "family tree" of Life. Phylogenetic trees not only describe the evolution of a group of organisms but can also be constructed from the organisms within a particular environment or ecosystem, such as the human microbiome. In this way, they can describe how this ecosystem evolved and what its fu
Researchers have identified a novel protein complex that regulates Aurora B localization to ensure that chromosomes are correctly separated during cell division. The complex, NWC, is made up of three proteins: NOL11, WDR43, and Cirhin. In the absence of NWC, Aurora B did not accumulate at centromeres, and chromosome movement and alignment were impaired. Together, these results show that NWC is req
People in what is now Washington State were smoking Rhus glabra, a plant commonly known as smooth sumac, more than 1,400 years ago. The discovery marks the first-time scientists have identified residue from a non-tobacco plant in an archeological pipe.
Scientists have published an extensive review of spin-gapless semiconductors (SGSs), a new class of 'zero bandgap' materials which have fully spin polarised electrons and holes, and first proposed in 2008. The study tightens the search for materials that would allow for ultra-fast, ultra-low energy 'spintronic' electronics with no wasted dissipation of energy from electrical conduction.
UNIGE scientists developed a neuro-computer model which helps explain how the brain identifies syllables in natural speech. The model uses the equivalent of neuronal oscillations produced by brain activity to process the continuous sound flow of connected speech. The model functions according to a theory known as predictive coding, whereby the brain optimizes perception by constantly trying to pre
At Stanford, he created the world’s first successful sleep clinic and taught a popular class on sleep and dreams. (If he caught students dozing, he’d wake them with a water gun.)
The previous and current editors in chief of a psychology journal have apologized for publishing an article about which one of them writes, “in retrospect I can certainly see that their article does feed into racist narratives.” Earlier this month, we reported that the authors of “Declines in Religiosity Predict Increases in Violent Crime—but Not … Continue reading

Before the arrival of European colonizers, the Amazonian Indigenous peoples cultivated their food – cassava, corn, pineapple, peppers and squash, among other things. The food of the ancient civilizations of the Amazon also largely consisted of the fruits of palm and Brazilian nut trees. The protection and management of trees across generations have affected the diversity of the rainforest right up

Indium nitride is a promising material for use in electronics, but difficult to manufacture. Scientists have now developed a new molecule that can be used to create high-quality indium nitride, making it possible to use it in, for example, high-frequency electronics.
The thin, slippery layer of cartilage between the bones in the knee is magical stuff: strong enough to withstand a person's weight, but soft and supple enough to cushion the joint against impact, over decades of repeat use. That combination of soft-yet-strong has been hard to reproduce in the lab. But now, researchers say they've created an experimental gel that's the first to match the strength a
A team used a simple process to implant atoms precisely into the top layers of ultra-thin crystals, yielding two-sided structures with different chemical compositions. The resulting materials, known as Janus structures after the two-faced Roman god, may prove useful in developing energy and information technologies.
Traffic density is the most important factor for much the air pollutant nitrogen dioxide (NO2). However, weather also has an influence, according to a new study, which evaluated the influence of weather conditions on nitrogen dioxide concentrations in Saxony 2015 to 2018. It was shown that wind speed and the height of the lowest air layer are the most important factors that determine how much poll

A s companies and organizations of all sorts have scrambled to institute a zero-tolerance policy on racism over the past few weeks, some of them have turned out to be more interested in signaling their good intentions than punishing actual culprits. This emphasis on appearing rather than being virtuous has already resulted in the mistreatment of innocent people—not all of them public figures or w
Many observers breathed a sigh of relief when Bill Barr was confirmed as attorney general. Here was a respected professional who had served in the post once before in an honorable administration. Now, just a year and a half later, what a disappointment he has proved. The man cannot be trusted. Think of the intentionally misleading account he gave of the Mueller report, at a time when the public a
Sincerity is the key to every great Will Ferrell comedy. His classics, such as Anchorman: The Legend of Ron Burgundy and Talladega Nights: The Ballad of Ricky Bobby , are surreal satires of American arrogance. But they work because the title characters are earnest creations—buffoons invested with the genuine belief that what they’re doing is special. That makes Ferrell an ideal match for a movie

The statues are falling. On Monument Avenue in Richmond, Virginia, Confederate President Jefferson Davis has been yanked off his pedestal . In Philadelphia, the former mayor and virulent racist Frank Rizzo was transferred to a storage facility. Across the Atlantic, a crowd of protesters grabbed Edward Colston, a 17th-century slave trader, and dumped him into Bristol Harbor. Yet there is another r
Here’s a helpful phrase from history: “emergencies of over-patriotism.” That’s from the New-York Tribune in 1909, from one of the many newspaper accounts from the turn of the century lamenting the DIY fireworks launched by the masses every Independence Day. American industrialization and immigration had created an urban working class in need of ways to blow off steam, and pyrotechnics provided an
Scientists are currently pushing on an ethical boundary. Will out of body gestation ever replace the experience of human birth? The lamb is sleeping. It lies on its side, eyes shut, ears folded back and twitching. It swallows, wriggles and shuffles its gangly legs. Its crooked half-smile makes it look content, as if dreaming about gambolling in a grassy field. But this lamb is too tiny to venture
“We have the greatest testing program anywhere in the world,” US President Donald Trump told reporters on June 23. “We test better than anybody in the world. Our tests are the best in the world, and we have the most of them. By having more tests, we find more cases.” Trump went on to say the US had done 25 million tests—far more than the couple of million that “even large countries” had done elsw
