Superhighways The Mayans were incredibly advanced — that's nothing new. But gauging the extent of their civilization has always proved tricky, since so much of it lies hidden by the impenetrably dense rainforests of Guatemala. But now, using light detection and ranging (LiDAR), scientists have revealed a network of nearly 800 Maya settlements and a sprawling web of interconnected "superhighways."

When love is in the air, what's happening in the brain? For many years, biologists would answer, "Oxytocin!"

But lately, neuroscientists have been revising their thinking about oxytocin. Experime

The virus that causes COVID-19, called SARS-CoV-2, uses its spike protein in order to stick to and infect our cells. The final step for the virus to enter our cells is for part of its spike protein to act like a twist tie, forcing the host cell's outer membrane to fuse with the virus.

During the Cold War, NATO had nightmares of hundreds of thousands of Moscow's troops pouring across international borders and igniting a major ground war with a democracy in Europe. Western governments feared that such a move by the Kremlin would lead to escalation—first to a world war and perhaps even to a nuclear conflict. That was then; this is now. Russia's invasion of Ukraine is nearly a yea

It took almost 75 years for researchers to record the first footage of the remains of the Titanic, buried over 2 miles beneath the surface of the Atlantic Ocean. It then took them nearly 40 years more to release the footage in its fuller form. This week, the Woods Hole Oceanographic Institution (WHOI) released 80 minutes of untrimmed footage from its first filmed voyage to the sunken ship. Capture

Less than 50 percent of F-22 Raptors are available and ready for service. The recent hyper-focus on the Chinese "spy balloon" that drifted over the US earlier this month has everyone gazing skyward. While they were looking, the US Air Force spotted a few more suspicious objects, including one that it and Canadian forces shot down over Yukon last week. Despite the rush to declare alien contact, th

At Its Core Dark energy, hypothesized to permeate the universe and affect it at the grandest scale, has remained deeply mysterious — down to basic details like where it resides. Now, new research makes a bold claim: it may be hiding out in black holes. The prevailing theory maintained by physicists is that dark energy is distributed evenly across the cosmos and is responsible for the accelerating

The basic story of Fox News and the 2020 election is well understood. Fox's relatively small news operation covered the vote count accurately; this coverage infuriated President Donald Trump, the MAGA base, and Fox's opinion stars; some viewers temporarily flipped to further-right outlets, such as Newsmax; and Fox panicked. But thanks to Dominion Voting Systems, which is pursuing a $1.6 billion d

Unless you're a fan of comic-book series (and Netflix film) The Old Guard, you may never have heard of the Scythians before now, but chances are you've seen some aspect of their influence, down through the long years of human history. They are believed to originate from ancient Iran around 900 B.C., spreading from Central Asia into what is now Ukraine and parts of Russia. They were a formidable fo

Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales. A recent study quantified the lipid content in Fraser River Chinook salmon — the southern resident's preferred meal — and found that spring-run Chinook salmon, the earliest to arrive to the Salish Sea are lipid-rich and energy dense; a critical factor for the killer whales

Shake It Off With Microsoft's new Bing AI and other artificial intelligence software becoming the biggest news story of 2023 thus far, it's easy to forget that AI chatbots have been around for a long time — and that Microsoft's old one, Tay, is the literal blueprint for out-of-control algorithms . It was March 2016, back when Donald Trump's presidency still seemed impossible and the concept of a

The Visible and Infrared Imaging Radiometer Suite (VIIRS) on the recently launched NOAA-21 satellite started collecting Earth science data from its day-night band (DNB) and its thermal emissive bands (TEB) on Feb. 9, 2023. This comes three months after the satellite launched from Vandenberg Space Force Base on Nov. 10, 2022.

After completing the first sample depot on another world, the rover continues its hunt for Mars rocks worthy of study on Earth.

To study how stars and planets are born we have to look at star cradles hidden in cool clouds of dust. Far-infrared telescopes are able to pierce through those clouds. Conventionally, niobium nitride bolometers are used as the detectors, despite their low operating temperature of 4 Kelvin (-269° Celsius).

Global warming is affecting vineyards and the taste of wines.

Very soon, we need to become fossil free, not only in the energy sector, but in industry as well. Hydrocarbons or other raw chemicals can be produced in principle using renewable energy and abundant molecules such as water and carbon dioxide with the help of electrocatalytically active materials. But at the moment, those catalyst materials either consist of expensive and rare materials or lack eff

Archaeological work ahead of a rehabilitation project at a Gettysburg battlefield revealed an unexploded artillery shell from the Civil War.

Global warming is affecting vineyards and the taste of wines.

Scientists have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting — even after 8 months back on Earth.

New observations have brought to light that stars can form through the dynamic interaction of gas within interstellar gas clouds. This process unfolds faster than previously assumed, research within the FEEDBACK programme on board the flying observatory SOFIA revealed.

EPFL researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with applications in 6G communications and beyond.

Climate change and the projected savannization of the Brazilian Amazon threaten most land-based mammals that live there, new research shows. "We're losing Amazon forest as we speak." Threatened animals include jaguars, ocelots, anteaters, and capybara, but also animals that use both forest and savanna habitats, such as pumas and giant armadillos. The study in the journal Animal Conservation also

Yesterday, Senator John Fetterman, the Pennsylvania Democrat who suffered a stroke at the near-peak of his political campaign last May, announced that he was checking into Walter Reed National Military Medical Center to treat a case of obdurate depression. The discussion since then (at least in the mainstream press, and among his Democratic colleagues) has focused, rightly, on what a sea change t

Scientists found that 2-oxo-imidazole-containing dipeptides (2-oxo-IDPs) exhibit very high antioxidant activity. Furthermore, they established a method to selectively and sensitively detect very small amounts of 2-oxo-IDPs and revealed for the first time that several types of 2-oxo-IDPs are contained in meat, including beef, pork, and chicken.

New research shows that the feathers of seabirds such as the Wandering Albatross can provide clues about their long-distance foraging, which could help protect these species from further decline.

56 million years ago, the Earth experienced one of the largest and most rapid climate warming events in its history: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming. This episode saw global temperatures rise by 5-8°C. It was marked by an increase in the seasonality of rainfalls, which led to the movement of large quantities of clay into the ocean,

Ice cores are a unique climate archive. Thanks to a new method, greenhouse gas concentrations in 1.5 million year old ice can be measured even more accurately.

Changing the structure of a dietary fiber commonly found in a range of food products has been found to promote healthy gut bacteria and reduce gas formation, a finding that could help people with intolerances to fiber and irritable bowel conditions.

Metabolic engineering is a field of plant biotechnology that seeks to genetically modify plant metabolic pathways to generate plant varieties with improved health benefits. Recently, scientists engineered potato and tomato plants to express the plant pigment betalain — found only in Caryophyllales and higher fungi. They found that while betalain-tomatoes conferred anti-inflammatory effects agains

I am sitting here envisioning a world where students all have their own private GPT model experience that knows them and teaches them a set curriculum. It's like a private teacher for every student. It knows how they learn, and how to test their understanding. At the same time, learning metrics can be gathered as part of the learning experience directly as opposed to standardized testing.

Tutorial here Code here OpenAI's Chat-GPT has gotten a lot of attention recently, imo for a lot of the right reasons (and some of the wrong reasons, but that's another topic). When I started thinking about how it could integrate with robotics, I couldn't stop thinking of C-3PO – a robot who was excellent at speaking like a human (and humanoids from other planets), even if he was not always right.

By 'clear' or 'clear-ish' I mean we can see definition with the naked eye. So something like the image of Pluto circa 2010 at the very least. The recent black hole image is amazingly detailed. What I don't mean is having seven pixels with two shades of color between them. An example of what I am anticipating would be if we took an image of Mars, we could see a white dot then the rest is red. Anal

Abstract Topologically protected magnon surface states are highly desirable as an ideal platform to engineer low-dissipation spintronics devices. However, theoretical prediction of topological magnons in strongly correlated materials proves to be challenging because the ab initio density functional theory calculations fail to reliably predict magnetic interactions in correlated materials. Here, w

Abstract We report multifunctional tendon-mimetic hydrogels constructed from anisotropic assembly of aramid nanofiber composites. The stiff nanofibers and soft polyvinyl alcohol in these anisotropic composite hydrogels (ACHs) mimic the structural interplay between aligned collagen fibers and proteoglycans in tendons. The ACHs exhibit a high modulus of ~1.1 GPa, strength of ~72 MPa, fracture tough

Abstract Remote measurement of vital sign parameters like heartbeat and respiration rate represents a compelling challenge in monitoring an individual's health in a noninvasive way. This could be achieved by large field-of-view, easy-to-integrate unobtrusive sensors, such as large-area thin-film photodiodes. At long distances, however, discriminating weak light signals from background disturbance

Abstract At presynaptic active zones (AZs), conserved scaffold protein architectures control synaptic vesicle (SV) release by defining the nanoscale distribution and density of voltage-gated Ca 2+ channels (VGCCs). While AZs can potentiate SV release in the minutes range, we lack an understanding of how AZ scaffold components and VGCCs engage into potentiation. We here establish dynamic, intravit

Abstract High harmonic generation (HHG) from solid-state crystals in strong laser fields has been understood by the band structure of the solids, which is based on the periodic boundary condition (PBC) due to translational invariance. For the systems with PBC due to rotational invariance, an analogous Bloch theorem can be applied. Considering a ring-type cluster of cyclo[18]carbon as an example,

Abstract Alternative polyadenylation (APA) creates distinct transcripts from the same gene by cleaving the pre-mRNA at poly(A) sites that can lie within the 3′ untranslated region (3′UTR), introns, or exons. Most studies focus on APA within the 3′UTR; however, here, we show that CPSF6 insufficiency alters protein levels and causes a developmental syndrome by deregulating APA throughout the transc

Abstract Humans work together in groups to tackle shared problems and contribute to local club goods that benefit other group members. Whereas benefits from club goods remain group bound, groups are often nested in overarching collectives that face shared problems like pandemics or climate change. Such challenges require individuals to cooperate across group boundaries, raising the question how c

Abstract White matter tracts form the structural basis of large-scale brain networks. We applied brain-wide tractography to diffusion images from 30,810 adults (U.K. Biobank) and found significant heritability for 90 node-level and 851 edge-level network connectivity measures. Multivariate genome-wide association analyses identified 325 genetic loci, of which 80% had not been previously associate

Abstract To harvest and reuse low-temperature waste heat, we propose and realize an emergent concept—barocaloric thermal batteries based on the large inverse barocaloric effect of ammonium thiocyanate (NH 4 SCN). Thermal charging is initialized upon pressurization through an order-to-disorder phase transition, and the discharging of 43 J g −1 takes place at depressurization, which is 11 times mor

Abstract The loss of discrete morphological traits, the most common evolutionary transition, is typically driven by changes in developmental gene expression. Mutations accumulating in regulatory elements of these genes can disrupt DNA binding sites for transcription factors patterning their spatial expression, or delete entire enhancers. Regulatory elements, however, may be silenced through chang

Abstract Graphene quantum dots (GQDs) are nanosized graphene derivatives with unique photoluminescence (PL) properties that have advantages in optoelectronic applications due to their stable blue light emission. However, aggregation-caused quenching (ACQ) of GQDs limits the practical applications on light-emitting diodes. Here, we suppress the ACQ phenomena of GQDs by reducing the size and conver

Abstract Spindle positioning within the oocyte must be tightly regulated. In mice, the spindle is predominantly assembled at the oocyte center before its migration toward the cortex to achieve the highly asymmetric division, a characteristic of female meiosis. The significance of the initial central positioning of the spindle is largely unknown. We show that initial spindle positioning at the ooc

Abstract Little is known about three-dimensional (3D) genome organization in skeletal muscle stem cells [also called satellite cells (SCs)]. Here, we comprehensively map the 3D genome topology reorganization during mouse SC lineage progression. Specifically, rewiring at the compartment level is most pronounced when SCs become activated.

The 2015–2018 summer droughts have been exceptional in large parts of Western and Central Europe over the last 400 years, in terms of the magnitude of drought conditions. This indicates an influence of human-made global warming. However, multi-year droughts have occurred frequently in the 17th and 18th century, although not as severe.

Mars is infamous for its intense dust storms, some of which kick up enough dust to be seen by telescopes on Earth. When dust particles rub against each other, as they do in Martian dust storms, they can become electrified. New research shows that one particularly efficient way to move chlorine from the ground to the air on Mars is by way of reactions set off by electrical discharge generated in du

There are a couple of recent stories that remind me that perhaps the most powerful thing in the world is political will. Often politicians and motivational speakers will say something along the lines of, "We can do anything, if we put our minds to it." While this sounds like feel-good pablum, I think there is some truth to it (with a bunch of caveats regarding "anything"). We (collectively) have

Republicans and Democrats, at odds over so much, share a common dilemma in the 2024 election: Donald Trump. One party still loves Trump but fears him as its nominee. The other party fears Trump's return to office but might welcome his renomination. Even though more than half the country says it wants to move on from Trump, we can't escape his influence on the race. The problem for Republicans is
