A small chemical change — shifting the position of two hydrogen atoms — makes the difference between mice that are healthy or that have insulin resistance and fatty liver, major risk factors for diabetes and heart disease. Making the change prevented the onset of these symptoms in mice fed a high-fat diet and reversed these prediabetes obese mice. Published in Science, the finding pinpoints a 'd
A strain of the common cold virus has been found to potentially target, infect and destroy cancer cells in patients with bladder cancer, a new study in the medical journal Clinical Cancer Research reports. No trace of the cancer was found in one patient following treatment with the virus.
A study of high school and college football players suggests that biomarkers in the blood may have potential use in identifying which players are more likely to need a longer recovery time after concussion.
In a new study, researchers show that a paradigm on a global temperature drop that started around 15 million years ago cannot be upheld. With the help of a computer model they explain the Earth's cooling with an increased 'reactivity' of the land surface that has led to a decrease in CO2 in the atmosphere, reducing the Earth's natural green house effect.
An optimized version of the CRISPR-Cas9 gene-editing system prevents hearing loss with no detectable off-target effects in so-called Beethoven mice, which carry a mutation that causes profound hearing loss in humans and mice alike. Results offer proof of principle for using the same gene-editing technique for other inherited human genetic diseases.
A particularly aggressive, metastasizing form of cancer, HER2-positive breast cancer, may be treated with nanoscopic particles "imprinted" with specific binding sites for the receptor molecule HER2. The selective binding of the nanoparticles to HER2 significantly inhibits multiplication of the tumor cells.
In a world first, scientists have found a new way to direct stem cells to heart tissue. The findings could radically improve the treatment for cardiovascular disease, which causes more than a quarter of all deaths in the UK (1).
Irrigation dropped maximum temperatures by one to three degrees Fahrenheit on average while increasing minimum temperatures up to four degrees compared to unirrigated farms or forests, new research shows. In all, irrigated farms experienced a three- to seven-degree smaller range in daily temperatures compared to other land uses. These effects persisted throughout the year.

Around 0.9 billion hectares of land worldwide would be suitable for reforestation, which could ultimately capture two thirds of human-made carbon emissions. The Crowther Lab of ETH Zurich has published a study in the journal Science that shows this would be the most effective method to combat climate change.
The record-breaking belt of brown algae stretches from West Africa to the Gulf of Mexico — and it's likely here to stay, says a team led by the USF College of Marine Science
Scientists have used satellite observations to identify the largest bloom of macroalgae in the world, the Great Atlantic Sargassum Belt — a heavy mass of brown algae stretching from West Africa to the Gulf of Mexico.
In the first study to quantify how many trees the Earth can support, where, and how much carbon they could store, researchers report that Earth could support enough additional trees to cut carbon levels in the atmosphere by nearly 25% — levels not seen for almost a century.
Researchers have discovered a biochemical oxygen sensing system conserved across biological kingdoms, which allows both plant and animal cells to sense and respond appropriately to changes in oxygen levels — an ability central to the survival of most forms of life.

Restoration of the Earth's forests is the world's most effective solution to climate change available today and has the potential to capture two thirds of man-made carbon emissions, finds landmark research by the Crowther Lab, published today in the journal Science.
In 2018, as seaweed piled up on beaches throughout the Caribbean, it began to rot. Already stinking and sulfurous, the thick layers began to attract insects and repel tourists. The seaweed—a type of brown algae called sargassum—had grown in the ocean and washed ashore in unprecedented quantities. It prevented fishers from getting into the water, and entangled their nets and propellers. It entangl
Becoming a gang member is often assumed to imply few long-term life opportunities beyond dying or being imprisoned. In most of the world, however, this only concerns a minority of gang members, with the majority tending to "mature out" out of their gang, and becoming (more or less) upstanding members of society.
The world could support nearly 1 billion hectares of extra forest, covering the size of the United States and giving us 20 more years to tackle climate change
Many mainstays in our lives—phones, personal music libraries and movies—began as pay-as-you-go services. But subscription services are starting to rule, from iTunes shifting to Apple Music, and "all-you-can-watch" subscriptions to the Netflix catalogue.

CRISPR-Cas nucleases are powerful tools for manipulating nucleic acids; however, targeted insertion of DNA remains a challenge, as it requires host cell repair machinery. Here we characterize a CRISPR-associated transposase from cyanobacteria Scytonema hofmanni (ShCAST) that consists of Tn7-like transposase subunits and the type V-K CRISPR effector (Cas12k). ShCAST catalyzes RNA-guided DNA transp
The COPII-cargo adaptor complex Lst1-Sec23 selectively sorts proteins into vesicles that bud from the endoplasmic reticulum (ER) and traffic to the Golgi. Improperly folded proteins are prevented from exiting the ER and are degraded. ER-phagy is an autophagic degradation pathway that uses ER-resident receptors. Working in yeast, we found an unexpected role for Lst1-Sec23 in ER-phagy that was inde
Conformational dynamics are essential for proteins to function. We adapted time-resolved serial crystallography developed at x-ray lasers to visualize protein motions using synchrotrons. We recorded the structural changes in the light-driven proton-pump bacteriorhodopsin over 200 milliseconds in time. The snapshot from the first 5 milliseconds after photoactivation shows structural changes associ
Organisms must respond to hypoxia to preserve oxygen homeostasis. We identify a thiol oxidase, previously assigned as cysteamine (2-aminoethanethiol) dioxygenase (ADO), as a low oxygen affinity (high- K m O 2 ) amino-terminal cysteine dioxygenase that transduces the oxygen-regulated stability of proteins by the N-degron pathway in human cells. ADO catalyzes the conversion of amino-terminal cystei
Civic honesty is essential to social capital and economic development but is often in conflict with material self-interest. We examine the trade-off between honesty and self-interest using field experiments in 355 cities spanning 40 countries around the globe. In these experiments, we turned in more than 17,000 lost wallets containing varying amounts of money at public and private institutions an
Lightweight magnesium alloys are attractive as structural materials for improving energy efficiency in applications such as weight reduction of transportation vehicles. One major obstacle for widespread applications is the limited ductility of magnesium, which has been attributed to dislocations failing to accommodate plastic strain. We demonstrate, using in situ transmission electron microscope
The restoration of trees remains among the most effective strategies for climate change mitigation. We mapped the global potential tree coverage to show that 4.4 billion hectares of canopy cover could exist under the current climate. Excluding existing trees and agricultural and urban areas, we found that there is room for an extra 0.9 billion hectares of canopy cover, which could store 205 gigat
The electronic character of photoexcited molecules can abruptly change at avoided crossings and conical intersections. Here, we report direct mapping of the coupled interplay between electrons and nuclei in a prototype molecule, iodine monobromide (IBr), by using attosecond transient absorption spectroscopy. A few-femtosecond visible pulse resonantly excites the , Y(0 + ), and Z(0 + ) states of I
Pelagic Sargassum is abundant in the Sargasso Sea, but a recurrent great Atlantic Sargassum belt (GASB) has been observed in satellite imagery since 2011, often extending from West Africa to the Gulf of Mexico. In June 2018, the 8850-kilometer GASB contained >20 million metric tons of Sargassum biomass. The spatial distribution of the GASB is mostly driven by ocean circulation. The bloom of 2011
Recent developments have enabled the practical realization of optical elements in which the polarization of light may vary spatially. We present an extension of Fourier optics—matrix Fourier optics—for understanding these devices and apply it to the design and realization of metasurface gratings implementing arbitrary, parallel polarization analysis. We show how these gratings enable a compact, f
Multiple cytosolic innate sensors form large signalosomes after activation, but this assembly needs to be tightly regulated to avoid accumulation of misfolded aggregates. We found that the eIF2α kinase heme-regulated inhibitor (HRI) controls NOD1 signalosome folding and activation through a process requiring eukaryotic initiation factor 2α (eIF2α), the transcription factor ATF4, and the heat shoc
The N-terminal residue influences protein stability through N-degron pathways. We used stability profiling of the human N-terminome to uncover multiple additional features of N-degron pathways. In addition to uncovering extended specificities of UBR E3 ligases, we characterized two related Cullin-RING E3 ligase complexes, Cul2 ZYG11B and Cul2 ZER1 , that act redundantly to target N-terminal glyci
Neural circuits emerge through the interplay of genetic programming and activity-dependent processes. During the development of the mouse olfactory map, axons segregate into distinct glomeruli in an olfactory receptor (OR)–dependent manner. ORs generate a combinatorial code of axon-sorting molecules whose expression is regulated by neural activity. However, it remains unclear how neural activity
How food production first entered eastern Africa ~5000 years ago and the extent to which people moved with livestock is unclear. We present genome-wide data from 41 individuals associated with Later Stone Age, Pastoral Neolithic (PN), and Iron Age contexts in what are now Kenya and Tanzania to examine the genetic impacts of the spreads of herding and farming. Our results support a multiphase mode
One hectare of ocean in which fishing is not allowed (a marine protected area) produces at least five times the amount of fish as an equivalent unprotected hectare, according to new research published today.
Have you ever seen a fairy? They exist, and may very well be in your garden. But you would need a high-powered microscope to spot the dainty creatures.
If you could ask British insects about the habitats they prefer, they'd probably tell you that you can't improve on grassland that's rich with wildflowers. For farmers, though, grassland is said to be "improved" if it has been treated with fertiliser and sown with fast growing grasses.
Our two great American holidays are, of course, Thanksgiving and the Fourth of July. They're particularly American: Independence Day, for obvious reasons.

There are some that are fortunately defunct: hours-long orations by stuffed-shirt politicians. There are some innovations that one hopes do not become traditions: 60-ton tanks rolling through Washington, D.C., most notably. And there is one that has faded with time, yet is worth prese
John Adams predicted in a 1776 letter that the nation would mark the anniversary of its independence as "the most memorable Epocha in the History of America," hosting a great anniversary festival that ought to be "solemnized" forever after with "Pomp and Parade … Shews, Games, Sports, Guns, Bells, Bonfires and Illuminations from one End of this Continent to the other." That was prescient. This ye
On June 29, a video appeared showing masked activists wearing black clothing—the garb commonly associated with "antifa," the self-described anti-fascist movement—assaulting the conservative journalist Andy Ngo in Portland, Oregon. As if in unison, conservative publications published articles accusing the "left," "liberal journalists," and "reporters" of condoning the attack. That's a disturbing c
MOMBASA, Kenya—In 2007, the Bill & Melinda Gates Foundation said it was committed to eradicating malaria across the globe. By then, it was late to the game. That year, Chinese scientists working with a Chinese philanthropist and his company, New South, had already begun eradicating malaria from the small African nation of Comoros. Now they're setting their sights on a more ambitious location: Ken

In times of crisis, we often 'build a wall' that separates the part of our lives that feels out of control from the parts that are more in control. This is healthy and can help us maintain perspective. Nations, too, build walls during times of crisis. But those walls can't be designed to isolate ourselves from others; rather, they need to delineate what is working and what isn't. Upheaval: Turnin
There is so much we do not know about what occurred 200 years ago, let alone 1000 or further back, but obviously there was no internet, no multi-terabyte hard drives. I wonder what historians in 4019 will know about what occurred in our lifetime or even care to know. Obviously the significance of an event and its impact has a large role in the way we remember, but now so much seemingly useless an

Many bacteria contain cytoplasmic chemoreceptors that lack sensor domains. Here, we demonstrate that such cytoplasmic receptors found in 8 different bacterial and archaeal phyla genetically couple to metalloproteins related to β-lactamases and nitric oxide reductases. We show that this oxygen-binding di-iron protein (ODP) acts as a sensor for chemotactic responses…
Ligand–receptor binding and unbinding are fundamental biomolecular processes and particularly essential to drug efficacy. Environmental water fluctuations, however, impact the corresponding thermodynamics and kinetics and thereby challenge theoretical descriptions. Here, we devise a holistic, implicit-solvent, multimethod approach to predict the (un)binding kinetics for a generic ligand–pocket mod
The progressive accumulation, aggregation, and spread of α-synuclein (αSN) are common hallmarks of Parkinson's disease (PD) pathology.

Loud noises can be scary for pups (Deposit Photos/) The Fourth of July can be a miserable day for dogs. The fireworks make scaredy-cats out of many canines. That's because dogs, like humans, are hardwired to be afraid of sudden, loud noises. It is what keeps them safe. Some dogs, though, take that fear to the extreme with panting, howling, pacing, whining, hiding, trembling, and even self-injury

Nature Communications, Published online: 03 July 2019; doi:10.1038/s41467-019-10755-3 The inactive X (Xi)-specific S1/S2 chromosome compartments are merged by SMCHD1, but how the S1/S2 structure is constructed is unclear. The authors find that PRC1 drives the formation of S1/S2s and that the stepwise folding process of the Xi facilitates Xist RNA spreading between Xi compartments.
Nature Communications, Published online: 03 July 2019; doi:10.1038/s41467-019-10795-9 Depression and transient ischaemic attacks are tightly regulated but the neural circuits underlying depression-modulated ischaemic injury are not known. Here, the authors show that the locus coeruleus-CA1 pathway is involved in depression-associated ischaemia susceptibility.
In Bohemian Rhapsody (2018), the movie about the British band Queen, the scene that sticks in my mind depicts the Live Aid concert in London in 1985. Queen belt out their best-loved songs and the crowd is singing along, swaying, clapping and stamping its feet. I could empathise a potent sense of togetherness in the audience, a feeling of cohesion between thousands of fans, coming not only from a
Save The Date In November, Chinese scientist He Jiankui shocked the world when he announced that he had brought CRISPR-edited human babies into the world. But the Chinese government has kept quiet in the face of news that a third CRISPR birth is expected soon, according to MIT Technology Review . In January, Stanford bioethicist William Hurlbut announced that He had gene-hacked a third embryo and
In their study, published in Cell, the researchers demonstrated that specific groups of neurons, known as neuronal ensembles, have a causal role in behavior. The researchers used new optical and analytical tools to identify cortical ensembles in mice while they performed a visual task. They also used high-resolution optogenetics to simultaneously target selected neurons with single-cell precision,
Researchers have discovered two distinct subtypes of pancreatic neuroendocrine tumors – known as pNETs – that have dramatically different risks of recurrence following surgical treatment [or surgery]. The finding could yield predictive tests, ease anxiety in patients whose tumors are found to be unlikely to recur, while focusing vigilant follow-up monitoring on patients with pNETs having a higher
This is… absolutely never a good plan. (Deposit Photos/) The travel world seems to be divided into those who try to bring the smallest, lightest bag possible, even for months at a time ("one-bagging") and those who act with reckless abandon and bring more than they could ever need. I've tried both ends of the spectrum and they both have their flaws; the ideal situation is to pack exactly what y
Researchers look at the role of diet in the ability of the ancient Maya to withstand periods of severe climatic stress. They found that an increase in the elite Maya's preference for a maize-based diet may have made the population more vulnerable to drought, contributing to its societal collapse.
The Sex Talk Henry T. Greely is the director of Stanford University's Center for Law and the Biosciences, as well as its Program in Neuroscience and Society. Clearly, the guy knows a thing or two about technology and the role it plays in people's lives — and he's now predicting that technological advances will one day make sex for reproduction a thing of the past. "My strongest prediction is in t
Nature, Published online: 04 July 2019; doi:10.1038/d41586-019-02081-xBones found in the Philistine city of Ashkelon and dating to the twelfth century bc hint at European heritage.
A type of white blood cell that has been especially susceptible to being deceived by pancreatic cancer cells into not attacking them can be 're-programmed' via a specially designed molecule that activates a protein found on their surfaces. The finding, which are the cover story of the July 3, 2019 issue of the Science Translational Medicine. Despite being the 3rd leading cause of cancer deaths, on
At high enough levels, Retinol Binding Protein 3 (or RBP3) prevents the development of diabetic retinopathy. If introduced early enough in the development of the disease, RBP3 was shown to reverse the effects of the complication in rodent models of diabetes.
Agitoxin-2 (AgTx2) from scorpion venom is a potent blocker of K+ channels. Here, we observed the binding dynamics of AgTx2 to the KcsA channel using high-speed atomic force microscopy. From the images obtained, single-molecule kinetic analyses revealed that the affinity of the channel for AgTx2 increased during persistent binding and decreased during persistent dissociation. We propose a four-stat
