The field of polymer membrane design is primarily based on empirical observation, which limits discovery of new materials optimized for separating a given gas pair. Instead of relying on exhaustive experimental investigations, we trained a machine learning (ML) algorithm, using a topological, path-based hash of the polymer repeating unit. We used a limited set of experimental gas permeability dat
Mercury (Hg) biomagnification in aquatic food webs is a global concern; yet, the ways species traits and interactions mediate these fluxes remain poorly understood. Few pathways dominated Hg flux in the Colorado River despite large spatial differences in food web complexity, and fluxes were mediated by one functional trait, predation resistance. New Zealand mudsnails are predator resistant and a
Existing long α-helix mimicking necessitates the retention of most natural amino acid residues to maintain their biological activity. Here, we report the exploration of helical sulfono–AApeptides with entire unnatural backbones for their ability to structurally and functionally mimic glucagon-like peptide 1 (GLP-1). Our findings suggest that efficient construction of novel GLP-1 receptor (GLP-1R
Directly quantifying a spatially varying stress in soft materials is currently a great challenge. We propose a method to do that by detecting a change in visible light absorption. We incorporate a spiropyran (SP) force–activated mechanophore cross-linker in multiple-network elastomers. The random nature of the network structure of the polymer causes a progressive activation of the SP force probe
The causative agent of Legionnaires disease, Legionella pneumophila , translocates the phosphocholine transferase AnkX during infection and thereby posttranslationally modifies the small guanosine triphosphatase (GTPase) Rab1 with a phosphocholine moiety at S76 using cytidine diphosphate (CDP)–choline as a cosubstrate. The molecular basis for Rab1 binding and enzymatic modification have remained
Anti–programmed cell death 1 ligand 1 (PD-L1) therapy is extraordinarily effective in select patients with cancer. However, insufficient lymphocytic infiltration, weak T cell–induced inflammation, and immunosuppressive cell accumulation in the tumor microenvironment (TME) may greatly diminish the efficacy. Here, we report development of the FX@HP nanocomplex composed of fluorinated polymerized CX
CO gas molecule not only could selectively kill cancer cells but also exhibits limited anticancer efficacy because of the lack of active tumor-targeted accumulation capability. In this work, a multistage assembly/disassembly strategy is developed to construct a new intelligent nanomedicine by encapsulating a mitochondria-targeted and intramitochondrial microenvironment–responsive prodrug (FeCO-TP
Mounting evidence suggests that the gut microbiota contribute to colorectal cancer (CRC) tumorigenesis, in which the symbiotic Fusobacterium nucleatum ( Fn ) selectively increases immunosuppressive myeloid-derived suppressor cells (MDSCs) to hamper the host's anticancer immune response. Here, a specifically Fn -binding M13 phage was screened by phage display technology. Then, silver nanoparticles
Extrachromosomal circular DNAs (eccDNAs) are somatically mosaic and contribute to intercellular heterogeneity in normal and tumor cells. Because short eccDNAs are poorly chromatinized, we hypothesized that they are sequenced by tagmentation in ATAC-seq experiments without any enrichment of circular DNA. Indeed, ATAC-seq identified thousands of eccDNAs in cell lines that were validated by inverse
Chronic wounds in diabetes undergo a lifetime risk of developing into diabetic foot ulcers. Oxygen is crucial to wound healing by regulating cell proliferation, migration, and neovascularization. However, current oxygen therapies, including hyperbaric oxygen (HBO) and topical gaseous oxygen (TGO), mainly employ gaseous oxygen delivery, which is much less effective in penetrating the skin. Here, w

A new study led by Adam Schreiner-McGraw, a postdoctoral hydrology researcher at the University of California, Riverside, modeled shrub encroachment on a sloping landscape and reached a startling conclusion: Shrub encroachment on slopes can increase the amount of water that goes into groundwater storage. The effect of shrubs is so powerful that it even counterbalances the lower annual rainfall amo
When researchers from the University of Colorado Anschutz Medical Campus, Aurora, used a combination of two specific blood-clotting tests, they found critically ill patients infected with Coronavirus Disease 2019 (COVID-19) who were at high risk for developing renal failure, venous blood clots, and other complications associated with blood clots, such as stroke.
Until now, electron spins and orbitals were thought to go hand in hand in a class of materials that's the cornerstone of modern information technology; you couldn't quickly change one without changing the other. But a study at the Department of Energy's SLAC National Accelerator Laboratory shows that a pulse of laser light can dramatically change the spin state of one important class of materials
The study now published in Nature Cell Biology reveals more information on the capacity of plants, identified as 'epigenetic memory,' which allows recording important information to, for example, remember prolonged cold in the winter to ensure they flower at the right time during the spring.
Scientists from the CNRS and the ENS-PSL in France and Monash University in Australia have shown that the brain suppresses information from the outside world, such as the sound of a conversation, during the sleep phase linked to dreaming. This ability could be one of the protective mechanisms of dreams. The study was carried out in collaboration with the Centre du Sommeil et de la Vigilance, Hôtel
In the absence of a COVID-19 vaccine, social distancing measures may need to remain in place until mid-2021, according to a new study. A cautious, measured approach to relaxing COVID-19 restrictions will protect the most vulnerable members of society and support the health service, experts say. Researchers used a detailed mathematical model calibrated against data on the age distribution of cases
DIY A team of engineers and nuclear physicists has an unusual plan to revolutionize the nuclear energy industry: they want to 3D print a functional reactor in their lab.

London has seen steeper decline in R rate but north has slower fall in infections, and estimates vary Coronavirus – latest updates See all our coronavirus coverage Transmission rates of Covid-19 remain dangerously close to levels that could bring a second wave, even before the easing of some restrictions this week, as the focus shifts to transmission rates in the north of England. The latest offi
One of the big (and so far unanswered) questions about the coronavirus epidemic is what kind of immunity people have after becoming infected. This is important for the idea of "re-infection" (is it even possible?) and of course for vaccine development. We're getting more and more information in this area, though, and this new paper is a good example. A team from the La Jolla Institute for Immunol
If history is any indication, the economic fallout and increased political demands caused by the coronavirus could pressure government leaders into building a new safety net for lower income groups, new research suggests. "However, the political possibilities that emerge from the current crisis will likely be colored by real world beliefs and prejudices about who is worthy of economic support and
An interdisciplinary, international team of scientists has reconstructed the paleoecology the Paleo-Agulhas Plain, a now-drowned landscape on the southern tip of Africa that was high and dry during glacial phases of the last 2 million years and may have been instrumental in shaping the evolution of early modern humans.
Modern media isn't necessarily harming our memory systems though it is impacting what we remember. We used to retain reams of valuable information; now we're more likely to memorize URLs and passwords. The process of deep learning is being sacrificed to our addiction to novelty. You'll likely have to be Gen X (or older) to understand this question: do you remember your childhood phone number? Edu
Far from being a mental drain, parenthood seems to rewire gray matter for improved empathy and emotional regulation. A recent study published in Nature Scientific Reports found that couples who co-parent together display similar brain activity, suggesting they become greatly attuned to each other. These findings suggest time spent parenting together improves care, coordination, and empathy. When
Video by Jackson Tisi In November 2012, Leon Ford was pulled over by two Pittsburgh police officers. It was a routine traffic stop—at least, it was supposed to be, until one of the officers, who is white, mistook Ford , who is black, for a wanted gang member. Ford was able to confirm his identity with a license, insurance, and registration papers. Nonetheless, one of the officers jumped into Ford
The writer Robin Sloan's speculative short story "The Conspiracy Museum," part of The Atlantic 's new Shadowland project, is set at the grand opening of a Smithsonian institution—one dedicated to the human tendency to conjecture (wildly, and sometimes dangerously) about invisible social forces. Sloan's story not only recognizes the prominence of this kind of thinking in the history of organized s

A team of researchers from the University of California and CNRS-Sorbonne Université has identified four species of deep-sea worms that until now have been referred to as Elvis worms. In their paper published in the journal ZooKeys, the group describes the worms, how they were named, and some odd behavior they managed to capture on video.
Of the roughly 4,300 exoplanets confirmed to date, about ten percent of them are classified as "hot Jupiters." These are planets with masses between about 0.4 and 12 Jupiter-masses and orbital periods less than about 110 days (implying that they orbit close to their star—usually much closer than Mercury is to the Sun—and have hot surface temperatures). A "hot Neptune" has a smaller mass, closer to
The oxidation of Earth's early atmosphere and ocean played an important role in the evolution of life.

The first finished "Loyal Wingman" prototype. (Boeing /) The US military's most futuristic and problematic fighter jet is the F-35, a very expensive aircraft that costs the Air Force around $82 million a pop. Exorbitant price tags like that, and other considerations, are spurring aircraft makers and air forces to think about ways to augment the fighter jets they have—planes flown by people—with s
Trying to hack fitness is a multi-million-dollar industry; we've all seen at least one ad featuring a purported miracle product that claims it can make people lose weight and look great—without even trying. From low-effort exercise machines to strange-ingredient diets to fat-burning belts and bands, there's no shortage of attempts to make it easy to be fit. A gene therapy trial performed on mice

Recently, researchers at the Shanghai Astronomical Observatory have presented a new model that for the first time simultaneously explains the origins of both the Fermi bubbles and the Galactic center biconical X-ray structure, which was discovered in 2003.
Researchers from Tokyo Medical and Dental University (TMDU) identified a new phosphorylation site of Ulk1 as a novel regulating mechanism of alternative autophagy. By inducing DNA damage in MEFs using etoposide, the researchers found that Ulk1 became phosphorylated at the serine 746 site by RIPK3 in alternative autophagy, but not canonical autophagy (see Figure). These findings could help to under
Researchers from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences developed a noninvasive ultrasound neuromodulation technique, which could potentially modulate neuronal excitability without any harm in the brain.
Researchers keen to work out why some people are suffering from 'long tail' form of the virus Coronavirus – latest updates See all our coronavirus coverage In mid-March Paul Garner developed what he thought was a "bit of a cough". A professor of infectious diseases, Garner was discussing the new coronavirus with David Nabarro, the UK's special envoy on the pandemic. At the end of the Zoom call, N
Most experts warn that lifting coronavirus lockdown orders too soon could lead to a resurgence of cases unless there is a robust program to test, trace, and isolate infected people. But there are political and economic questions, too — and in the absence of such testing, the public is getting restless.

Entanglement is at the heart of quantum technologies that promise large advances in computing, communications and sensing, for example, detecting gravitational waves.
The December 2004 trans-oceanic tsunami, generated by the 9.2 Sumatra-Andaman earthquake, changed the way people look at the sea and was a true turning point in tsunami science. The greatest impact of the tsunami was felt in Indonesia, Sri Lanka, India, and Thailand where more than 200,000 people lost their lives.
It's chow time. (Amazon/) When you're rushing through coffee, collecting dry cleaning to drop off, and answering emails at the same time, sometimes you forget (or almost forget) to feed your dog before leaving the house. That's one scenario in which a pet feeder comes in handy. Another? When you want to take a weekend trip but can't find a cat sitter. Give yourself (and your best friend) a bit of
A pair of gigantic gamma-ray bubbles centered on the core of the Milky Way galaxy were discovered by the Fermi Gamma-ray Space Telescope 10 years ago. But how these so-called "Fermi bubbles" arose was a mystery.
Researchers have long known that all of the millions of malaria parasites within an infected person's body move through their cell cycle at the same time. They multiply in sync inside red blood cells, then burst out in unison every few days. But how the parasites keep time was unclear. Now, a study finds that malaria has its own internal clock that causes thousands of genes to ramp up and down at
The Hyper-Angular Rainbow Polarimeter (HARP) CubeSat achieved "first light" on April 16. The tiny satellite sent back its very first image over Europe with bright splashes of colors defining clouds and aerosols, which are tiny particles in the atmosphere. HARP's measurements help us better understand how clouds and aerosols impact weather, climate and air quality.

For the past 70 years, the best indicator of life expectancy for a patient with glioblastoma — the most common and the most aggressive brain cancer — has been age at diagnosis. Now, an international team of scientists has experimentally validated a predictor that is not only more accurate but also more clinically relevant: a pattern of co-occurring changes in DNA abundance levels, or copy number
The Washington Post's depiction of autism has shifted over the years from a focus on 'cause and cure' toward one of acceptance and accommodation, say the authors of a study that examined 315 articles published from 2007 to 2017.
A new study documents a robust antiviral immune response to SARS-CoV-2 in a group of 20 adults who had recovered from COVID-19. The findings show that the body's immune system is able to recognize SARS-CoV-2 in many ways, dispelling fears that the virus may elude ongoing efforts to create an effective vaccine.

Taking antidepressants during pregnancy does not appear to increase the child's risk of autism, according to a new meta-analysis. The review in the American Journal of Psychiatry examines 14 studies, many of which identified a connection between antidepressant use during pregnancy and autism. However, that research failed to account for ascertainment bias, which occurs when one group of patients
The prevalence of asymptomatic cases—people infected with the virus who can spread it to others but don't feel sick—is one of the most challenging aspects of the coronavirus pandemic, researchers say. In Iceland, where a broad testing effort resulted in 5% of the country's population getting tested for COVID-19, a lab study suggested that as many as 50% of people who have the disease show no symp
When German and US soccer kick off this summer, there will be no crowds. That might squelch the home-field advantage—and the emotion that drives players.
There are many examples of mathematical breakthroughs achieved in prison. Maybe the most famous is from the French mathematician Andre Weil, who came up with his hugely influential conjectures while in a military prison in Rouen, France. Another mathematical giant, Srinivasan Ramanujan, started off with no formal training in mathematics and produced most of his revolutionary results in complete is

Researchers at Luleå University of Technology have developed a method to study how muscle cells in the blood vessels of the lung permanently contract because of long-term oxygen deficiency. This phenomenon leads to increased pressure in the vessels of the lung and the strain on the heart increases. The effect is evident in lung diseases such as chronic obstructive pulmonary disease (COPD) and the
Personer med en speciell genvariant behöver äta mer socker för att känna söt smak, och de får också mer karies i tänderna. Det visar en ny avhandling vid Umeå universitet. Avhandlingen visar också att även personer som inte har den vanligaste kariesbakterien i munnen kan drabbas. – En slutsats är att man skulle kunna använda smaktest eller gentest för att identifiera personer som är i riskgrupp o

När mjölkkor utfodras med mycket spannmål och bönor som komplement till vallfoder äter de mer potentiella livsmedel än vad de producerar i form av mjölk. Men om man ersätter spannmål och bönor med biprodukter, såsom betfiber, drank, rapsmjöl och kli, så producerar korna mycket mer livsmedel än vad de äter. Människor och lantbrukets djur konkurrerar om de proteinfoder som jorden kan producera. Joh
