MIT researchers have developed an automated chemical synthesis machine that can take over many tedious aspects of chemical experimentation, freeing chemists to spend time on the more analytical and creative aspects of their work.
Finally providing insights into the spin behavior of sun-like stars outside our solar system, researchers now report that, much like the sun, some other solar-type stars spin faster at their equators than at their poles.
The three stages of mammalian backbone evolution are far clearer now, thanks to work by a team of researchers that examined fossilized backbones of primitive mammal ancestors and applied novel statistical analyses.
The exponential growth in overall mortality from unintentional drug overdoses in recent decades is a composite of multiple underlying sub-epidemics of different drug types, each with its own unique set of social and geographic characteristics, reports a new study.
By identifying specific biomarkers preserved alongside fossils of oval-shaped life forms from the Ediacaran Period, fossils from which are typically considered one of the greatest mysteries in paleontology, researchers say the ovular organism is not a fungus or protist, as some have thought, but an early animal.
Searching for a more direct connection between the gut and the brain, Duke researchers were shocked to see that distance spanned by a single synapse, relaying the signal in less than 100 milliseconds, less than the blink of an eye. The finding in the journal Science has profound implications for the understanding of appetite and appetite suppressants, most of which target slow-acting hormones rath
A new study is challenging the long-held belief that specialization in mammal backbones date back to the earliest land animals. Evidence suggests that the spine gained regions during mammal evolution, with the first — located in close proximity to the shoulders and front legs — appearing some 250 million years ago, just as dramatic changes began to appear in the forelimbs of animals known as non
Dolphins swim, horses gallop, and humans walk on two legs — mammals are able to move in lots of different ways. That's because we have unique backbones. And scientists exploring how mammals' backbones evolved have discovered that the key to our complex spines lies in mammals' flexible shoulders.
"We used our data-driven tools to derive significant insight into how the process works that allows us to design the correct additives to get the desired outcomes," Sigman said. The results allow chemists to control which stereochemical product comes out of the reaction, simply by selecting the right ligand. It's more than just a laboratory convenience, though. The study also reveals much more abo
Death rates from drug overdoses in the US have been on an exponential growth curve that began at least 15 years before the mid-1990s surge in opioid prescribing, suggesting that overdose death rates may continue along this same historical growth trajectory for years to come. These findings suggest that, to be successful, prevention efforts must extend beyond control of specific drugs to address de
A non-pathogenic fungus can expand in the intestines of antibiotic-treated mice and enhance the severity of allergic airways disease, according to a study published Sept. 20 in the open-access journal PLOS Pathogens by David Underhill of Cedars-Sinai Medical Center, and colleagues. The findings suggest that alterations in gut microbiota induced by intestinal fungi might be a previously unrecognize
In 2014, a dengue outbreak unexpectedly occurred in Tokyo. What does that mean for the 2020 summer Olympics and Paralympics being held in the city? Researchers report this week in PLOS Neglected Tropical Diseases that new controls and frameworks are recommended to detect dengue and other infectious diseases and help prevent their spread during the summer games.
Oval-shaped Dickinsonia lifeform existed at least 20m years before the 'Cambrian explosion' of animal life A fossilised lifeform that existed 558m years ago has been identified as the oldest known animal, according to new research. The findings confirm that animals existed at least 20m years before the so-called Cambrian explosion of animal life, which took place about 540m years ago and saw the
Better understanding of the dynamics of the current U.S. overdose epidemic may aid in the development of more effective prevention and control strategies. We analyzed records of 599,255 deaths from 1979 through 2016 from the National Vital Statistics System in which accidental drug poisoning was identified as the main cause of death. By examining all available data on accidental poisoning deaths
The differentially rotating outer layers of stars are thought to play a role in driving their magnetic activity, but the underlying mechanisms that generate and sustain differential rotation are poorly understood. We report the measurement using asteroseismology of latitudinal differential rotation in the convection zones of 40 Sun-like stars. For the most significant detections, the stars' equat
Phosphorothioate nucleotides have emerged as powerful pharmacological substitutes of their native phosphodiester analogs with important translational applications in antisense oligonucleotide (ASO) therapeutics and cyclic dinucleotide (CDN) synthesis. Stereocontrolled installation of this chiral motif has long been hampered by the systemic use of phosphorus(III) [P(III)]–based reagent systems as
Fast, high-fidelity measurement is a key ingredient for quantum error correction. Conventional approaches to the measurement of superconducting qubits, involving linear amplification of a microwave probe tone followed by heterodyne detection at room temperature, do not scale well to large system sizes. We introduce an approach to measurement based on a microwave photon counter demonstrating raw s
Here we report an anomalous porous molecular crystal built of C–H···N-bonded double-layered roof-floor components and wall components of a segregatively interdigitated architecture. This complicated porous structure consists of only one type of fully aromatic multijoint molecule carrying three identical dipyridylphenyl wedges. Despite its high symmetry, this molecule accomplishes difficult tasks
The enigmatic Ediacara biota (571 million to 541 million years ago) represents the first macroscopic complex organisms in the geological record and may hold the key to our understanding of the origin of animals. Ediacaran macrofossils are as "strange as life on another planet" and have evaded taxonomic classification, with interpretations ranging from marine animals or giant single-celled protist
A unique characteristic of mammals is a vertebral column with anatomically distinct regions, but when and how this trait evolved remains unknown. We reconstructed vertebral regions and their morphological disparity in the extinct forerunners of mammals, the nonmammalian synapsids, to elucidate the evolution of mammalian axial differentiation. Mapping patterns of regionalization and disparity (het
Synthetic protein-level circuits could enable engineering of powerful new cellular behaviors. Rational protein circuit design would be facilitated by a composable protein-protein regulation system in which individual protein components can regulate one another to create a variety of different circuit architectures. In this study, we show that engineered viral proteases can function as composable
The RNA-guided endonuclease Cas9 cleaves its target DNA and is a powerful genome-editing tool. However, the widely used Streptococcus pyogenes Cas9 enzyme (SpCas9) requires an NGG protospacer adjacent motif (PAM) for target recognition, thereby restricting the targetable genomic loci. Here, we report a rationally engineered SpCas9 variant (SpCas9-NG) that can recognize relaxed NG PAMs. The crysta
Hoffmann et al . (Reports, 23 February 2018, p. 912) report the discovery of parietal art older than 64,800 years and attributed to Neanderthals, at least 25 millennia before the oldest parietal art ever found. Instead, critical evaluation of their geochronological data seems to provide stronger support for an age of 47,000 years, which is much more consistent with the archaeological background i
Antagonistic interactions are abundant in microbial communities and contribute not only to the composition and relative proportions of their members but also to the longer-term stability of a community. This Review will largely focus on bacterial antagonism mediated by ribosomally synthesized peptides and proteins produced by members of host-associated microbial communities. We discuss recent fin
The periodic stripes and spots that often adorn animals' coats have been largely viewed as self-organizing patterns, forming through dynamics such as Turing's reaction-diffusion within the developing skin. Whether preexisting positional information also contributes to the periodicity and orientation of these patterns has, however, remained unclear. We used natural variation in colored stripes of
The brain is thought to sense gut stimuli only via the passive release of hormones. This is because no connection has been described between the vagus and the putative gut epithelial sensor cell—the enteroendocrine cell. However, these electrically excitable cells contain several features of epithelial transducers. Using a mouse model, we found that enteroendocrine cells synapse with vagal neuron
Perovskite solar cells (PSCs) have witnessed rapidly rising power conversion efficiencies, together with advances in stability and upscaling. Despite these advances, their limited stability and need to prove upscaling remain crucial hurdles on the path to commercialization. We summarize recent advances toward commercially viable PSCs and discuss challenges that remain. We expound the development
Biological processes that require orderly progression, such as growth and differentiation, proceed via regulatory checkpoints where the cell waits for signals before continuing to the next state. Implementing such control would allow genetic engineers to divide complex tasks into stages. We present genetic circuits that encode sequential logic to instruct Escherichia coli to proceed through a lin
Chemical synthesis generally requires labor-intensive, sometimes tedious trial-and-error optimization of reaction conditions. Here, we describe a plug-and-play, continuous-flow chemical synthesis system that mitigates this challenge with an integrated combination of hardware, software, and analytics. The system software controls the user-selected reagents and unit operations (reactors and separat
Spatiotemporal instabilities are widespread phenomena resulting from complexity and nonlinearity. In broad-area edge-emitting semiconductor lasers, the nonlinear interactions of multiple spatial modes with the active medium can result in filamentation and spatiotemporal chaos. These instabilities degrade the laser performance and are extremely challenging to control. We demonstrate a powerful app
Sun-like stars rotate up to two and a half times faster at the equator than at higher latitudes, a finding by researchers at NYU Abu Dhabi that challenges current science on how stars rotate.
Designing a new chemical synthesis can be a laborious process with a fair amount of drudgery involved—mixing chemicals, measuring temperatures, analyzing the results, then starting over again if it doesn't work out.
Scientists from The Australian National University (ANU) and overseas have discovered molecules of fat in an ancient fossil to reveal the earliest confirmed animal in the geological record that lived on Earth 558 million years ago.
Stereochemistry is a science of reflection. Two chemical molecules with the same composition and structure, but with one as the mirror image of the other, can produce wildly varying effects. Controlling which molecule emerges from a given reaction is a critical, but sometimes poorly understood, process.
Around 558 million years ago, a strange … something dies on the floor of an ancient ocean. Its body, if you could call it that, is a two-inch-long oval with symmetric ribs running from its midline to its fringes. It is quickly buried in sediment, and gradually turns into a fossil. While it sits in place, petrifying, waiting, the world around it changes. The Earth's landmasses merge into a single
Active infections kill 4,000 people a day worldwide, more than AIDS does. But the notion that a quarter of the global population harbors silent tuberculosis is "a fundamental misunderstanding."

More than a quarter of providers were unable to say whether their state had expanded Medicaid, the national survey found. The survey also sought to assess the healthcare providers' views on the effects of the ACA.
Scientists says our survival depends on biodiversity. A natural climate strategy we often forget. Seeing our place among the Earth's living creatures. When we talk about the loss of habitat for animals, it's usually discussed in altruistic terms. Those who love animals are eager to fix it, while others feel it's our planet to do with what we will. It turns out that there may be a 100 percent self
Bill Gates, Mark Zuckerberg, and Ellen DeGeneres all dropped out of college, yet they became leaders in their fields. Their secret? Self-directed learning. Self-directed learning can help people expand their knowledge, gain new skills, and improve upon their liberal education. Following habits like Benjamin Franklin's five-hour rule, the 80/20 rule, and SMART goals can help self-directed learners
How do we know if we're looking at three apples or four? Researchers were able to demonstrate that some brain cells fire mainly for quantities of three, others for quantities of four and others for other quantities. A similar effect can be observed for digits: In humans, the neurons activated in response to a '2' are for instance not the same as the neurons activated for a '5'.

Modern X-ray imaging uses scintillator mate
In the modern world, people cooperate with other people including strangers all the time. We give blood, tip providers of various services, and donate to charity even though there is seemingly nothing in it for us. Now, researchers who've studied Hadza hunter-gatherer people in Tanzania over a six-year period have new and surprising insight into why people work together.
What prevents our cells being damaged due to overexposure to iron ions is a protein called lactoferrin, known for its ability to bind tightly to such ions. Researchers used a combined experimental and molecular dynamics simulation to study the changes in the structure of lactoferrin as it binds to iron ions.
Hookworms exploit a live fast/die young strategy in their South American fur seal pup hosts. As a result, they often kill their host, rather than finding a happy equilibrium. Scientists are concerned that this type of hookworm infection could eventually pose a risk to critically endangered populations of fur seals.
Astronomers report the first detection of matter falling into a black hole at 30% of the speed of light, located in the center of the billion-light year distant galaxy PG211+143. The team used data from the European Space Agency's X-ray observatory XMM-Newton to observe the black hole.
Although depression is one of the leading psychiatric disorders, its cause remains unclear. A recent study found that those affected by depressive disorder have a larger hypothalamus compared to their healthy counterparts. This could explain why many sufferers show increased levels of the stress hormone cortisol and are very often afflicted with periods of tension.
Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility.
In a move with the power to shake up the music industry, Spotify said Thursday that it will allow select artists to upload songs directly without record labels or distributors.
Over the past several years, CRISPR-Cas9 has moved beyond the lab bench and into the public zeitgeist. This gene-editing tool CRISPR-Cas9 holds promise for correcting defects inside individual cells and potentially healing or preventing many human ailments. But the Cas9 system alters DNA, not RNA, and some experts believe that being able to modify RNA ultimately may prove just as useful.
Consumers' credit cards are declined surprisingly often in legitimate transactions. One cause is that fraud-detecting technologies used by a consumer's bank have incorrectly flagged the sale as suspicious. Now MIT researchers have employed a new machine-learning technique to drastically reduce these false positives, saving banks money and easing customer frustration.
Scientists from the Salk Institute are reporting for the first time the detailed molecular structure of CRISPR-Cas13d, a promising enzyme for emerging RNA-editing technology. They were able to visualize the enzyme thanks to cryo-electron microscopy (cryo-EM), a cutting-edge technology that enables researchers to capture the structure of complex molecules in unprecedented detail.
The mood-altering drug MDMA — which promotes positive, friendly social interactions in humans by inhibiting serotonin uptake in nerve cells — has a similar behavioral effect in an octopus species, scientists reported today. This indicates that serotonin has been functioning as a regulator of social behavior for at least 500 million years, when the human and octopus lineages evolutionarily diverg
A rapid genetic test developed by Newcastle researchers has identified the first four patients with inherited mutations in a new disease gene, a building block of complex I called NDUFA6.
Hookworms exploit a live fast/die young strategy in their South American fur seal pup hosts, report Morris Animal Foundation-funded researchers at the University of Georgia.

A species of seed-feeding fly is critically damaging the seed production of multiple orchid species, as revealed by a group of Japanese researchers. If the damage caused by this fly is occurring long-term and across Japan, these already-endangered orchid species could become unable to reproduce using seeds, and their dwindling numbers will take a large hit.
Why do humans cooperate? For six years, researchers from the University of Pennsylvania have worked to answer this great puzzle, focusing on the Hadza, a nomadic hunter-gatherer population in Tanzania. New findings suggest that cooperation is flexible, not fixed.
A decade-long effort led by Stanford University School of Medicine scientists has been rewarded with the identification of the human skeletal stem cell.
Stanford scientists have measured the human 'exposome,' or the particulates, chemicals and microbes that individually swaddle us all, in unprecedented detail.
Today's kiwifruit, a member of the Chinese gooseberry family, contains about as much vitamin C as an orange. This extra boost in vitamin C production is the result of the kiwifruit's ancestors' spontaneously duplicating their DNA in two separate evolutionary events approximately 50-57 million and 18-20 million years ago, as reported September 20 in the journal iScience.
Human skeletal stem cells that become bone, cartilage, or stroma cells have been isolated from fetal and adult bones. This is the first time that skeletal stem cells, which had been observed in rodent models, have been identified in humans. The researchers were also able to derive the skeletal stem cells from human induced pluripotent stem cells, opening up new therapeutic possibilities. The disco
When people take MDMA, the drug popularly known as ecstasy, a rush of serotonin, dopamine, and oxytocin produces feelings of emotional closeness and euphoria, making people more interested than normal in connecting with other people.

Science It's time to stop pinning our hopes on pseudoscience. Americans love to take, deliver, and judge the results of polygraph tests. Too bad they're mostly worthless.
Scientists have challenged the theory of "love at first sight" after discovering that they can boost the reproductive success of zebrafish by pairing them by personality, rather than appearance.
The oil industry should pay more attention to human and organizational aspects in order to fundamentally improve safety. The industry does not learn enough from oil spills because learning is a conflict of interests: "Parties try to protect or promote their interest and try – consciously or subconsciously – to exclude each other from the learning process." This conclusion is the result of an inves
You may have seen it: the Nike ad in which tennis star Serena Williams ignores the judgements of others and chooses her own path. These and similar ads use storylines that have seemingly little to do with the brand itself in order to attract people to that brand.

The findings shed more light on how neurons differentiate into particular subtypes, with potential implications for the treatment of conditions such as Parkin
'Dry-hopping' beer enhances flavor but sometimes has undesirable side effects, such as an unexpectedly high alcohol content and high pressures. Now, new research explains the biochemical basis of these unintended consequences, which could help brewers create better 'hoppy' beverages.
Scientists have demonstrated a promising technique for measuring and mapping your exposome—the flecks of animate and inanimate stuff that surround you at all times.
When Gül Dölen first gave ecstasy to octopuses , she didn't know what to expect. Dölen is a neuroscientist at the Johns Hopkins School of Medicine who studies how the cells and chemicals in animal brains influence animals' social lives. Ecstasy, also known as MDMA, interests her because it's known to make people feel more sociable , more interested in others, and less defensive. The same effects
Earlier this week, Tucker Carlson did the thing Tucker Carlson is consummately good at doing: He got angry on national television. The Fox News host's performance, this time around, concerned the allegations of sexual assault Christine Blasey Ford has made against the Supreme Court nominee Brett Kavanaugh; Carlson, echoing an idea that has become a common one in the heated national debate that ha
"New U.S.-China Tariffs Raise Fears of an Economic Cold War," proclaimed a Washington Post headline. The New York Times alleged that the United States and China were already "on the cusp" of such a "new Cold War." Driving this hysteria was the Trump administration's Monday announcement unveiling tariffs on an additional $200 billion of Chinese imports, followed nearly immediately by a Chinese pro
Trendy workout clothes may advertise that special silver nanoparticles embedded in the fabric will cut the sweaty odor that builds up from repeated gym visits. It turns out there's some truth to these claims.
The first step in conducting online propaganda efforts and misinformation campaigns is almost always a fake social media profile. Phony profiles for nonexistent people worm their way into the social networks of real people, where they can spread their falsehoods. But neither social media companies nor technological innovations offer reliable ways to identify and remove social media profiles that d
In the realm of evolutionary biology and survival of the fittest, cooperation is a risky business. Yet humans do it on a scope and a scale unmatched by any group in the animal world.
Survey the shelves of most supermarkets and you'll no doubt be confronted with row upon row of food designed to appeal to children. Be it chicken nuggets or turkey twizzlers – many foods now bear little resemblance to their original ingredients – "junk foods" now line the supermarket shelves to appeal to young consumers.
A species of seed-feeding fly is critically damaging the seed production of multiple orchid species, as revealed by a group of Japanese researchers. If the damage caused by this fly is occurring long-term and across Japan, these already-endangered orchid species could become unable to reproduce using seeds, and their dwindling numbers will take a large hit.
Today's kiwifruit, a member of the Chinese gooseberry family, contains about as much vitamin C as an orange. This extra boost in vitamin C production is the result of the kiwifruit's ancestors' spontaneously duplicating their DNA in two separate evolutionary events approximately 50-57 million and 18-20 million years ago, as reported September 20 in the journal iScience.
We are all exposed to a vast and dynamic cloud of microbes, chemicals and particulates that, if visible, might make us look something like Pig-Pen from Peanuts.
By studying the genome of a kind of octopus not known for its friendliness toward its peers, then testing its behavioral reaction to a popular mood-altering drug called MDMA or "ecstasy," scientists say they have found preliminary evidence of an evolutionary link between the social behaviors of the sea creature and humans, species separated by 500 million years on the evolutionary tree.
Dozens of farmers and lawmakers stormed out of a meeting Thursday with France's new environment minister after he confirmed that two more bears would soon be released into the Pyrenees mountains.

The discovery of a microorganism that gives a candy-pink lagoon in central Spain its startling colour is providing new evidence for how life could survive on a high-salt diet on Mars or Europa. The Laguna de Peña Hueca, part of the Lake Tirez system in La Mancha, has very high concentrations of salt and sulphur and is a good analogue for chloride deposits found in the Southern highlands of Mars an
Birds have long inspired humans to create their own ways to fly. We know that soaring bird species that migrate long distances use thermal updrafts to stay in the air without using up energy flapping their wings. And glider pilots similarly use thermals currents and other areas of rising air in order to remain airborne for longer.
For ferrets, sex is a prolonged affair. In total, the act of mating might last up to three hours. Fortunately for the males of the species, they are packing a secret weapon to help them through this daunting task. Some modern mammals (including ferrets, mice, dogs and even apes) have a bone inside their penis, called the baculum.
A recent study from North Carolina State University finds that the tool most often used to assess the efficiency of nonprofit organizations isn't just inaccurate – it can actually be negatively correlated with efficiency.
About one person out of 500 has a heart condition known as hypertrophic cardiomyopathy (HCM). This condition causes thickening of the heart muscle and results in defects in the heart's electrical system. Under conditions of environmental stress such as exercise, HCM can result in sudden death. In other cases, patients may go undiagnosed, with their heart function declining gradually over decades.
A recent study finds that the tool most often used to assess the efficiency of nonprofit organizations isn't just inaccurate — it is negatively correlated with efficiency.

This much we know: There's a wide and stubborn gender gap, both in terms of pay and leadership opportunities . What we still can't figure out are the causes. Some argue that inflexible workplaces are to blame. Others point to sexist cultural norms and even outright discrimination . While the truth is probably a combination of all these factors, and more, another theory has gained ground in recent
The change can be baffling to many parents: Their young girls are masters of the universe, full of gutsy fire. But as puberty sets in, their confidence nose-dives, and those same daughters can transform into unrecognizably timid, cautious, risk-averse versions of their former self. Over the course of writing our latest book , we spoke with hundreds of tween and teen girls who detailed a striking

Quantum dots are nanometer-sized boxes that have attracted much scientific interest for use in nanotechnology because their properties obey quantum mechanics and are requisites to developing advanced electronic and photonic devices. Quantum dots that self-assemble during their formation are particularly attractive as tunable light emitters in nanoelectronic devices and for studying quantum physics
Molecular motors convert energy into unidirectional mechanical motion. Most biomolecular motors in cells use adenosine triphosphate (ATP) as a chemical energy source. Recently, however, Serratia marcescens chitinase A (SmChiA) has been rediscovered as a molecular motor working in extracellular environments without using ATP. Similar to a monorail car (Fig. 1), SmChiA has cleft-like polysaccharide
A class of supported Pd@NiO-x core@shell catalysts have been constructed for direct H2O2 generation. The optimized Pd@NiO-3/TiO2 exhibited high activity, superior selectivity, low degradation activity and excellent stability. The unique, cavity-contained interface structure can suppress the overbinding between Pd-core and (O-O)*, which is effective to prevent H2O formation and guarantees high sele

Recent months have seen a series of dramatic steps by the Trump administration with respect to the Israeli-Palestinian conflict: moving the U.S. embassy to Jerusalem, defunding the agency responsible for Palestinian refugees, cutting West Bank aid, shutting down the PLO mission in Washington, and persistently promising to present its own peace plan. The flurry of activity comes even as the prospe
Anita Hill's testimony in Congress triggered the first "Year of the Woman" in 1992, after she accused the Republican Supreme Court nominee Clarence Thomas of sexually harassing her. But that wave of enthusiasm and outrage mostly elected white women. The new allegation of sexual assault against Brett Kavanaugh, another Republican Supreme Court nominee, comes from a white woman. But in a rapidly di
Every four years, the American Society for Civil Engineers issues grades for the nation's infrastructure. In the most recent evaluation , released in 2017, America's overall infrastructure score was a D+, the same as in 2013. Although seven systems, including hazardous waste and levees, received modestly better grades than in the previous assessment, transit and solid waste, among others, did wor
In a mostly meaningless game in late July, the New York Mets went down 19–0 against the Washington Nationals in the fifth inning. The game devolved into a circus. Mets broadcasters gave up announcing and instead started reminiscing about the team's 1969 World Series victory and reading aloud from the media guide. Then, in the ninth inning, with the bull pen low on fresh arms, the veteran infielde
CNRS and EHESS researchers analyzed nearly 60 million political tweets posted during the 2017 presidential election in France.

About one person out of 500 has a heart condition known as hypertrophic cardiomyopathy (HCM). This condition causes thickening of the heart muscle and results in defects in the heart's electrical system. Under conditions of environmental stress such as exercise, HCM can result in sudden death. In other cases, patients may go undiagnosed, with their heart function declining gradually over decades.
A few minutes of high-intensity interval or sprinting exercise may be as effective as much longer exercise sessions in spurring beneficial improvements in mitochondrial function, according to new research.

At the start of 2018, NASA had two active rovers on Mars. Now, it has one—and it's having some issues. Earlier this summer, the Opportunity rover stopped communicating with Earth after a massive dust storm swept the planet and prevented sunlight from reaching its solar panels. The storm has mostly cleared, but NASA hasn't heard from the rover since June, and engineers are listening daily for any
