During pregnancy, the appropriate allocation of nutrients between the mother and the fetus is dominated by maternal–fetal interactions, which is primarily governed by the placenta. The syncytiotrophoblast (STB) lining at the outer surface of the placental villi is directly bathed in maternal blood and controls feto–maternal exchange. The STB is…
Artemisinin-resistant malaria parasites have emerged and have been spreading, posing a significant public health challenge. Antimalarial drugs with novel mechanisms of action are therefore urgently needed. In this report, we exploit a “selective starvation” strategy by inhibiting Plasmodium falciparum hexose transporter 1 (PfHT1), the sole hexose transporter in P. falciparum,…
Understanding the underlying mechanisms of COVID-19 progression and the impact of various pharmaceutical interventions is crucial for the clinical management of the disease.

Self-control of one's thoughts, feelings and behaviors is one of the personality traits that makes a child ready for school. And, it turns out, ready for life as well. A large study tracking 1,000 people from birth through age 45 has determined that people who had higher levels of self-control as children were aging more slowly than their peers at age 45. Their bodies and brains were healthier and
Experts explain how surgical microscopes are modified into slightly different optical configurations and equipped with specific imaging modalities and platforms for different surgical applications.
The transition from the Medieval Warm Period to the Little Ice Age was apparently accompanied by severe droughts between 1302 and 1307 in Europe. Researchers write that the 1302-07 weather patterns display similarities to the 2018 weather anomaly, in which continental Europe experienced exceptional heat and drought.
One sweaty, huffing, exercising person emits as many chemicals from their body as up to five sedentary people, according to a new study. And notably, those human emissions, including amino acids from sweat or acetone from breath, chemically combine with bleach cleaners to form new airborne chemicals with unknown impacts to indoor air quality.
Walk toward the White House during the final days of the Trump presidency, and you’ll get an unmistakable feel of a government under siege. Buildings near Pennsylvania Avenue are boarded up in anticipation of street violence. Monuments are choked with fencing. A tall metal barricade has been erected at Lafayette Square, just north of the White House, and is covered top to bottom with signs—welcom
In garden ponds and in oceans, in desert soil and in industrial water-cooling towers , matters of life and death are playing out unseen by the human eye. Here, giant viruses prey on single-celled hosts such as amoebas or algae. This microscopic bloodbath can happen on such a large scale that massive algae blooms visible on the ocean surface turn white, as dead algae fade to reveal their colorless
Providing supplemental oxygen to mothers during childbirth doesn’t benefit the baby, an analysis of 16 previous trials shows. Babies who suffer oxygen deficiencies during birth are at risk of brain damage that can lead to developmental delays, cerebral palsy, and even death. To prevent this, most women in labor undergo continuous monitoring of the baby’s heart rate and receive supplemental oxygen
Researchers demonstrate the first transparent solar cell. Their innovative technique rests on a specific part of the solar cell: the heterojunction, made up of thin films of materials responsible for absorbing light. By combining the unique properties of titanium dioxide and nickel oxide semiconductors, the researchers were able to generate an efficient, transparent solar cell.
A small portion of scientific papers are retracted for research that is in error or fraudulent. But those papers can continue to be cited by other scientists in their work, potentially passing along the misinformation from the retracted articles.
To stop biodiversity loss, Canada recently committed to protecting 30% of its land and sea by 2030. But making conservation decisions about where to locate new protected areas is complicated. It depends on data both about biodiversity and about a range of benefits (e.g. freshwater, climate regulation, recreation) that people get from nature. Despite the size of the country, new mapping suggests th
As they age, people with diabetes are more likely to develop Alzheimer's disease and other cognitive disorders than are people without diabetes.

Two studies show that Danes aren't quite as good as Chinese at discerning bitter tastes. The research suggests that this is related to anatomical differences upon the tongues of Danish and Chinese people.
Brain metastases can only develop if cancer cells exit the capillaries and enter into the brain tissue. To facilitate this step, cancer cells influence blood clotting, as scientists have now been able to show in mice. The cancer cells actively promote the formation of clots, which helps them to arrest in the brain capillaries and then penetrate through the vessel wall. Drugs that inhibit thrombin

Pathogenic germline mutations in PIGV lead to glycosylphosphatidylinositol biosynthesis deficiency (GPIBD). Individuals with pathogenic biallelic mutations in genes of the glycosylphosphatidylinositol (GPI)-anchor pathway exhibit cognitive impairments, motor delay, and often epilepsy. Thus far, the pathophysiology underlying the disease remains unclear, and suitable rodent models that mirror all s
Brown fat may protect against a range of diseases, researchers report. Unlike white fat, which stores calories, brown fat burns energy and scientists hope it may hold the key to new obesity treatments. But it has long been unclear whether people with ample brown fat truly enjoy better health. For one thing, it has been hard to even identify such individuals since it’s hidden deep inside the body.

Macrodomains are proteins that recognize and hydrolyze ADP ribose (ADPR) modifications of intracellular proteins. Macrodomains are implicated in viral genome replication and interference with host cell immune responses. They are important to the infectious cycle of Coronaviridae and Togaviridae viruses. We describe crystal structures of the conserved macrodomain from the…
Exaggerated airway hyperresponsiveness and inflammation are hallmarks of asthma, and lipopolysaccharide (LPS) exposure is linked to the severity of the disease and steroid resistance. To investigate the mechanisms underlying asthma exacerbation, we established a mouse model of LPS-induced steroid-resistant exacerbation on the background of house dust mite (HDM)-induced asthma to…
The recent observation of superconductivity in Nd0.8Sr0.2NiO2 has raised fundamental questions about the hierarchy of the underlying electronic structure. Calculations suggest that this system falls in the Mott–Hubbard regime, rather than the charge-transfer configuration of other nickel oxides and the superconducting cuprates. Here, we use state-of-the-art, locally resolved electron energy-loss..
Self-splicing proteins, called inteins, are present in many human pathogens, including the emerging fungal threats Cryptococcus neoformans (Cne) and Cryptococcus gattii (Cga), the causative agents of cryptococcosis. Inhibition of protein splicing in Cryptococcus sp. interferes with activity of the only intein-containing protein, Prp8, an essential intron splicing factor. Here, we…
Studies examining the long-term health consequences of residential displacement following large-scale disasters remain sparse.

This apparatus spans the inner and outer bacterial membranes and includes a helical needle protruding into the extracellular space. Thus far observed only in EPEC and…
Biodiversity is declining worldwide. Because species interact with one another and with their environment, losses of particular organisms alter the function of ecosystems. Our understanding of the global rates and specific causes of functional decline remains limited, however. Species losses also reduce the cumulative amount of extant evolutionary history (“phylogenetic…
The ability to control one’s own emotions, thoughts, and behaviors in early life predicts a range of positive outcomes in later life, including longevity. Does it also predict how well people age? We studied the association between self-control and midlife aging in a population-representative cohort of children followed from birth…
Exon splicing triggered by unpredicted genetic mutation can cause translational variations in neurodegenerative disorders. In this study, we discover Alzheimer’s disease (AD)-specific single-nucleotide variants (SNVs) and abnormal exon splicing of phospholipase c gamma-1 (PLCγ1) gene, using genome-wide association study (GWAS) and a deep learning-based exon splicing prediction tool. GWAS revealed.
Polarization of optical fields is a crucial degree of freedom in the all-optical analogue of electromagnetically induced transparency (EIT). However, the physical origins of EIT and polarization-induced phenomena have not been well distinguished, which can lead to confusion in associated applications such as slow light and optical/quantum storage. Here we…
Kallikrein (PKa), generated by activation of its precursor prekallikrein (PK), plays a role in the contact activation phase of coagulation and functions in the kallikrein-kinin system to generate bradykinin. The general dogma has been that the contribution of PKa to the coagulation cascade is dependent on its action on FXII….
We demonstrate, by direct, single-cell imaging kinetic measurements, that endogenous autofluorescence in HeLa cells is sensitive to the application of external magnetic fields of 25 mT and less. We provide spectroscopic and mechanistic evidence that our findings can be explained in terms of magnetic field effects on photoinduced electron transfer…
Despite the omnipresence of colloidal suspensions, little is known about the influence of colloid shape on phase transformations, especially in nonequilibrium. To date, real-space imaging results at high concentrations have been limited to systems composed of spherical colloids.

Hepatitis delta virus (HDV) is an unusual RNA agent that replicates using host machinery but exploits hepatitis B virus (HBV) to mobilize its spread within and between hosts. In doing so, HDV enhances the virulence of HBV. How this seemingly improbable hyperparasitic lifestyle emerged is unknown, but it underpins the…
The CA (capsid) domain of immature HIV-1 Gag and the adjacent spacer peptide 1 (SP1) play a key role in viral assembly by forming a lattice of CA hexamers, which adapts to viral envelope curvature by incorporating small lattice defects and a large gap at the site of budding. This…
Physiological functioning and homeostasis of the brain rely on finely tuned synaptic transmission, which involves nanoscale alignment between presynaptic neurotransmitter-release machinery and postsynaptic receptors. However, the molecular identity and physiological significance of transsynaptic nanoalignment remain incompletely understood. Here, we report that epilepsy gene products, a secreted p
Sometimes, it’s easy for a computer to predict the future. Simple phenomena, such as how sap flows down a tree trunk, are straightforward and can be captured in a few lines of code using what mathematicians call linear differential equations. But in nonlinear systems, interactions can affect themselves: When air streams past a jet’s wings, the air flow alters molecular interactions, which alter t

Stealth A-12 jets were never meant to be seen, then one went missing in the Nevada desert. (US Air Force/) “Oxcart” was an odd nickname for the plane that killed pilot Walter Ray. Oxcarts are slow, cumbersome, and old. Ray’s A-12 jet, meanwhile, was fast, almost invisible, and novel. Among the US’s first attempts at stealth aircraft, it could travel as quickly as a rifle bullet, and fly at altitu
Man who shot to fame after his first jab says process second time round was ‘very efficient’ Coronavirus – latest updates See all our coronavirus coverage When Martin Kenyon went to receive his first coronavirus vaccination, his pithy responses after being accosted by a TV crew outside Guy’s hospital in London secured him “national treasure” status.

Is this way too over-optimistic and road signs etc. act as a failsafe if the network goes out etc. by being "hard copy" of data in a more permanent printed form? submitted by /u/SubaruToyotaFan1986 [link] [comments]
Considering that we become so advanced with interstellar travel that humans reproduce in the trillions throughout the universe, is it plausible to make it until the death of the universe? (Unless we discover a way to jump to another universe?) submitted by /u/Hot_Improvement_3598 [link] [comments]
I'm always thinking about the future of meat, as a meat lover. I'm also an animal lover too and don't want cattle to suffer. I think that when we achieve a viable way to culture meat, there is no reason for us to have bad meat or cheap cuts. Furthermore, I will finally taste premium beef like wagyu, or the best sushi meat not available in my country. Meat will be tastier, cheaper and healthier, s
The Human Genome Project was great; now can we study how to live together? All current political systems seem to have been discussed in depth – in the 2000 year old writings of the ancient world. I think we need our best and brightest to help figure out how ~7 billion of us can prosper together. I think that this area of study is essential and woefully undervalued. submitted by /u/Nearby-Onion359
By late November, Wyoming saw more than 1,000 new Covid-19 cases on multiple days — and the state’s 130 public health workers quickly became overwhelmed and unable to make any calls to the close contacts of those infected. But some county and tribal contact tracing teams continue to provide a vital resource.
Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-20366-y Residual stress in crystalline polymers can lead to material failure, but currently methods which can quantify residual stress in such materials are lacking. Here, by using fluorescent-type mechanochromophores, the authors develop a method to visualize and quantify low degrees of stress that arises from micro
Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-20381-z Structural and functional analysis of mitochondria from the human parasite Toxoplasma gondii reveals that its ATP synthase assembles into cyclic hexamers, arranged together in a form of pentagonal pyramids required for maintenance of cristae morphology in Apicomplexa.
Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-20359-x The human AAA+protein p97 plays an important role in cellular protein homeostasis.

Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-19366-9 Sex differences in fasting glucose and insulin have been identified, but the genetic loci underlying these differences have not. Here, the authors perform a meta-analysis of genome-wide association studies to detect sex-specific and sex-dimorphic loci associated with fasting glucose and insulin.
Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-20380-0 Green synthesis of graphite is a great challenge in the absence of the graphitization of amorphous carbon at high temperatures. Here, the authors report a green approach of synthesizing graphite from carbon dioxide at low temperature in seconds timescale.
Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-20406-7 Grasslands, and the livestock that live there, are dynamic sources and sinks of greenhouse gases, but what controls these fluxes remains poorly characterized. Here the authors show that on the global level, grasslands are climate neutral owing to the cancelling effects of managed vs. natural systems.
Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-20326-6 The use of short wavelength light in photolysis applications in chemistry and biology is limited by photolytic reaction yields, photodamage and photobleaching.

Nature Communications, Published online: 05 January 2021; doi:10.1038/s41467-020-20444-1 Using a single catalyst to mimic the two-step photosynthesis for CO2 conversion remains a challenge. Here, the authors report a simple Bi catalyst that can act as an electron-proton-transfer mediator to spatially and temporally separate H2O splitting and CO2 reduction reactions in CO2-to-CO conversion process
Grasslands are managed worldwide to support livestock production, while remaining natural or semi-natural ones provide critical services that contribute to the wellbeing of both people and the planet. Human activities are however causing grasslands to become a source of greenhouse gas emissions rather than a carbon sink. A new study uncovered how grasslands used by humans have changed our climate

Idag finns omkring 13 400 kärnvapen i världen. För att bidra till kärnvapennedrustning har regeringen bett Uppsala universitet att starta ett nytt kunskapscenter under år 2021.
The ‘carbon dividend’ is so elegant that it seems too good to be true. Governments should make it a post-pandemic priority Over the past year – when societies around the world have had to grapple with their greatest challenge in decades – climate change hasn’t been at the top of the agenda. But that doesn’t mean it’s gone away. Far from it – in fact, we just experienced the hottest September in 1
The Kambo fad: people are applying frog poison to burns created on their skin, making them vomit repeatedly and feel terrible. They think this torture has health benefits. There's no evidence that it does anything but poison them. Could anything be more ridiculous? The post first appeared on Science-Based Medicine .

We speak again to victims of the virus on the slow process of recovery, and the many setbacks they have endured since catching the disease As weeks have turned to months, and months roll into a year, the shadow cast by Covid-19 continues to lengthen – not least for many of those who have survived the disease. Earlier this year, some of those who caught the virus early in the pandemic told the Gua
From finally seeing the back of Donald Trump to being in a football stadium – the new year is full of promise You probably found a few things to enjoy about last year: you rediscovered your bicycle, perhaps, or your family, or even both, and learned to love trees. And don’t forget the clapping. Plus some brilliant scientists figured out how to make a safe and effective vaccine for a brand new vir
After Britain first went into lockdown to arrest the spread of the coronavirus last year, one had to contend with a number of mitigating factors when assessing the government’s performance. Yes, the country then suffered the worst death toll in Europe, and the worst economic slump, but Boris Johnson had “ followed the science ,” delaying a lockdown on the advice of his government’s medical and sc

A new study out of the University of Chicago Medicine following young adult drinkers for 10 years has found that individuals who reported the highest sensitivity to alcohol's pleasurable and rewarding effects at the start of the trial were more likely to develop an alcohol use disorder (AUD) over the course of the study.
The history of humanity is intimately entwined with the cosmos. The stars have influenced religion, art, mathematics and science – we appear naturally drawn to look up in wonder. Now, with modern technology, our view of the cosmos is changing. It is in reachable distance of our spacecrafts and satellites, and yet because of light pollution we see less and less of it here on Earth. Joined by the a
