Photoperiod is a major environmental cue that determines the floral transition from vegetative to reproductive development in flowering plants. Arabidopsis thaliana responds to photoperiodic signals mainly through a central regulator CONSTANS (CO). Although it has been suggested that phosphorylation of CO contributes to its role in photoperiodic control of flowering, how this is regulated so far
The emergence of the vortex beam with orbital angular momentum (OAM) has provided intriguing possibilities to induce optical transitions beyond the framework of the electric dipole interaction. The uniqueness stems from the OAM transfer from light to material, as demonstrated in electronic transitions in atomic systems. In this study, we report on the OAM transfer to electrons in solid-state syst
The genetics underlying heterosis, the difference in performance of crosses compared with midparents, is hypothesized to vary with relatedness between parents. We established a unique germplasm comprising three hybrid wheat sets differing in the degree of divergence between parents and devised a genetic distance measure giving weight to heterotic loci. Heterosis increased steadily with heterotic
Most cycads engage in brood-site pollination mutualisms, yet the mechanism by which the Cycadales entice pollination services from diverse insect mutualists remains unknown. Here, we characterize a push-pull pollination mechanism between a New World cycad and its weevil pollinators that mirrors the mechanism between a distantly related Old World cycad and its thrips pollinators. The behavioral co
Three-dimensional (3D) structures at the nanometer length scale play a crucial role in modern devices, but their fabrication using traditional top-down approaches is complex and expensive. Analogous to atomic lattices, block copolymers (BCPs) spontaneously form a rich variety of 3D nanostructures and have the potential to substantially simplify 3D nanofabrication. Here, we show that the 3D superl
Africa hosts the greatest human genetic diversity globally, but legacies of ancient population interactions and dispersals across the continent remain understudied. Here, we report genome-wide data from 20 ancient sub-Saharan African individuals, including the first reported ancient DNA from the DRC, Uganda, and Botswana. These data demonstrate the contraction of diverse, once contiguous hunter-g
Solutions to poverty and ecosystem degradation are often framed as conflicting. We ask whether Indonesia’s national anti-poverty program, which transfers cash to hundreds of thousands of poor households, reduced deforestation as a side benefit. Although the program has no direct link to conservation, we estimate that it reduced tree cover loss in villages by 30% (95% confidence interval, 10 to 50
Recent Antarctic surface climate change has been characterized by greater warming trends in West Antarctica than in East Antarctica. Although this asymmetric feature is well recognized, its origin remains poorly understood.

When a sessile droplet containing a solute in a volatile solvent evaporates, flow in the droplet can transport and assemble solute particles into complex patterns. Transport in evaporating sessile droplets has largely been examined in solvents that undergo complete evaporation. Here, we demonstrate that flow in evaporating aqueous sessile droplets containing type I collagen—a self-assembling poly
Archaeologists contend that it was our aptitude for symbolic, technological, and social behaviors that was central to Homo sapiens rapidly expanding across the majority of Earth’s continents during the Late Pleistocene. This expansion included movement into extreme environments and appears to have resulted in the displacement of numerous archaic human populations across the Old World. Tropical ra
Bone is built from collagen fibrils and biomineral nanoparticles. In humans, they are organized in lamellar twisting patterns on the microscale. It has been a central tenet that the biomineral nanoparticles are co-aligned with the bone nanostructure. Here, we reconstruct the three-dimensional orientation in human lamellar bone of both the nanoscale features and the biomineral crystal lattice from
The stimulator of interferon (IFN) genes (STING) pathway constitutes a highly important part of immune responses against various cancers and infections. Consequently, administration of STING agonists such as cyclic GMP-AMP (cGAMP) has been identified as a promising approach to target these diseases. In cancer cells, STING signaling is frequently impaired by epigenetic silencing of STING; hence, c
Although growth factors (GFs) are key molecules for regenerative medicine, their use has been limited by issues associated with suboptimal delivery systems and incomplete understanding of their signaling dynamics.

GABAergic interneurons are proposed to be critical for early activity and synapse formation by directly exciting, rather than inhibiting, neurons in developing hippocampus and neocortex. However, the role of GABAergic neurons in the generation of neonatal network activity has not been tested in vivo, and recent studies have challenged the excitatory nature of early GABA. By locally manipulating i
CD8 + T cells become functionally impaired or "exhausted" in chronic infections, accompanied by unwanted body weight reduction and muscle mass loss.

Yet studies only focus on treating patients with depression. Why are these l
Striking images of some five billion brain cell connections have been created by scientists, mapping a lifetime's changes across the brain in minute detail.
Which forces and mechanisms determine the height of mountains? A group of researchers has now found a surprising answer: It is not erosion and weathering of rocks that determine the upper limit of mountain massifs, but rather an equilibrium of forces in the Earth's crust. This finding is fundamentally new and important for the earth sciences.
A new study takes a closer look at the benefits of volunteering to the health and well-being of volunteers, both validating and refuting findings from previous research. The results verify that adults over 50 who volunteer for at least 100 hours a year (about two hours per week) have a substantially reduced risk of mortality and developing physical limitations, higher levels of subsequent physical
How we account for sand is important for understanding how reefs, atolls and coastal regions will cope with the effects of climate change. Scientists have discovered models for measuring sand were giving incorrect information and have developed more accurate engineering models.
Rent Freeze Thanks to a newly-passed resolution, Ithaca, New York could become the first U.S. city to cancel rent during the coronavirus pandemic. The resolution, which still requires state approval, would not only erase rent debt accrued over the last three months but also cancel rent payments for both tenants and small businesses going forward, Fast Company reports . If enacted, it would make I
A free app called Social Rhythms could help users understand their own sleep rhythms and shed light on how their biological clock is responding to lockdowns, researchers say. It can also give tips about how to shift their potentially disrupted rhythms to a more appropriate time. Almost overnight, the sleep and wake patterns of nearly four billion people may have changed because of COVID-19-spurre
Forskare föreslår ny strategi för utveckling av läkemedel och vaccin för att få ut mer av forskningen och samtidigt minska lidandet för försöksdjuren. Det handlar om att maximera den kunskap som varje försöksdjur bidrar med, snarare än att minimera antalet försöksdjur per experiment. Att utveckla läkemedel och behandlingsmetoder via djurförsök är en omfattande och viktig verksamhet. Förutom etisk
Leaked documents dated to earlier this week, obtained from the U.S. Centers for Disease Control and Prevention by Yahoo News , warn that new coronavirus cases are spiking again as Americans relax their social distancing practices. Even Dr. Anthony Fauci, the White House’s top infectious disease expert and a national figurehead against the virus, lamented this week that the outbreak has become his
According to a new survey from a popular dating website, 84 percent of people currently looking for a relationship through dating apps won't even consider dating someone with opposite political views. Additionally, 67 percent of the dating site's users have admitted to previously ending a relationship due to opposing political views. Licensed marriage therapist Dr. Gary Brown says that there is m
Need to store more? (Neal E. Johnson via Unsplash/) There was a time not long ago when almost any solid state drive would cost you an arm and a leg. That’s no longer the case. In fact, the standard for fast storage drives are now affordable even in sturdy and compact portable form. These portable drives can allow you to both reduce load times on your favorite games while easily bringing them with
Micrometeoroids that delivered stardust to asteroid 4 Vesta also carried water, researchers report. The formation of our solar system was a messy affair. Most of the material that existed before its formation—material formed around other, long-dead stars—was vaporized, then recondensed into new materials. But some grains of that material from before the sun’s birth still persist. These “stardust”
Deepfakes have struck a nerve with the public and researchers alike. There is something uniquely disturbing about these AI-generated images of people appearing to say or do something they didn’t. With tools for making deepfakes now widely available and relatively easy to use, many also worry that they will be used to spread dangerous misinformation. Politicians can have other people’s words put

Researchers have discovered a new set of signals that cells send and receive to prompt one type of fat cell to convert fat into heat. The signaling pathway, discovered in mice, has potential implications for activating this same type of thermogenic fat in humans.
The Trump campaign is busy fighting the battle for hearts and minds this week. Not voters’ hearts and minds—at the moment, the president’s reelection campaign is losing those left and right, with many recent polls showing his position slipping against the presumptive Democratic candidate, Joe Biden. Instead, the Trump reelection team is busy trying to soothe the president’s own troubled mind, and
Digital Dollar The U.S. federal government just awarded a grant to the blockchain startup Key Retroactivity Network Consensus (KRNC) to study the feasibility of integrating cryptocurrency into the economy. That doesn’t mean that the U.S. is going to pivot to a digital blockchain dollar, CoinDesk reports . Rather, the National Science Foundation funded KRNC because it’s interested in exploring new
Nearly 13 kilometers per year: that is the rate at which the wintering area of Bewick's swans has shifted east over the past 50 years.

The coronavirus pandemic has disrupted the education of at least 1.5 billion school students. That's more than 90% of the world's children. Although many schools in the west, along with private schools in the developing world, have continued some school activities online, more than 50% of learners worldwide do not have a household computer. The absence of face-to-face learning and opportunities fo
With the COVID-19 pandemic causing disruptions in the food supply chain, it's more important than ever to reduce food waste, says a University of Missouri Extension food safety specialist.
Researchers have developed a way to guide human stem cells into becoming important precursor cells that give rise to the placenta. Despite past efforts to understand pregnancy—both healthy and high-risk—the human placenta remains something of a mystery. Tissue samples are nearly impossible to obtain until after birth, making it difficult to study the placenta’s role in pregnancy complications. Th
Increase of greenhouse gas concentrations in the atmosphere generally tends to increase rainfall over India. Up to the year 2000, however, it appeared that the natural variability had been able to override this effect, resulting in the overall decrease. In addition to anthropogenic climate change, rainfall changes in recent decades are also influenced by natural sea surface temperature oscillation
Scientists at RCSI University of Medicine and Health Sciences have developed a new biomaterial that has the potential to accelerate bone regeneration by promoting an immune response that encourages repair and lowers the risk of inflammation.

A new Sino-German scientific collaboration investigating nitrogen in the soils of China's melting permafrost aims to get to the bottom of why emissions of nitrous oxide — an often overlooked greenhouse gas — are greater than they are supposed to be.
There has been an important fall in the total concentrations and evolution of the metal fraction towards their more innocuous forms, so the environmental risk is much reduced. The samples were taken in the same locations and by the same research group twenty years later. Sediments were analysed from six locations on the River Guadiamar and its main tributaries, from the area of the Aznalcóllar min
A new study from Lund University in Sweden shows that female birds benefit more from extra food in the winter. If females receive additional food, they do not need to reduce their body temperature as much as they would have otherwise, and the chances of surviving cold nights increase.
Researchers in the Medical University of South Carolina Clemson Bioengineering program report in Nature Biomedical Engineering that they have developed human cardiac organoids that model what happens in a heart attack in a microtissue less than 1 millimeter in diameter. This is the first model that accurately recapitulates the complex tissue dysfunction after a heart attack with multiple human cel
Advances in transportation technology—e-scooters and bike share, Lyft & Uber, and autonomous vehicles—are beginning to have profound impacts on cities. New mobility is changing not only how we travel, but also urban form and development itself. In the near future, we can expect differences in what public transit looks like, the layout of cities, and the places we spend our time. In turn, these cha
Children in social care have poorer mental health and perform worse in school than other children. But they have trust in the school staff and perform better after individual assessment at school. These are findings in a doctoral thesis from Linköping University.
During the early weeks of coronavirus in the UK, there was an obsessive focus on supermarkets and how they were handling the pandemic. It was as if traditional retail markets and small shops didn't exist. Many markets and traders, however, continued to provide essential goods and services during the lockdown, sometimes responding quicker and in more creative ways than larger stores.
During the height of the coronavirus pandemic, we became accustomed to face-masked shoppers, social distancing and one-way aisles at the grocery store. But most shocking was the scene at the supermarket meat case.
Insects that feed only on plants have a number of challenges to overcome. But they also have some active helpers to assist them with the supply of important nutrients. So-called symbiotic microorganisms make essential amino acids, vitamins, and enzymes available and in this way supplement and enrich the limited diet of their host insects. Reed beetles with their semi-aquatic lifestyle also have su
Do plants attacked by herbivores produce substances that are most effective against attackers in a targeted manner, or are herbivore-induced changes in a plant metabolism random, which could thwart the performance of herbivores?
Tropospheric ozone is produced via the photochemical reaction of volatile organic compounds, carbon monoxide, and nitrogen oxides in the presence of sunlight. Over the past 20 years, serious ozone pollution has been found in the most highly populated and industrialized city clusters in China, such as the Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta, and Sichuan Basin regions.

A survey conducted at the University of Basel and the Psychiatric Hospital of the University of Basel has investigated how sleep has changed during the Covid-19 lockdown. The 435 individuals surveyed — most of whom were women — reported sleeping longer while sleep quality deteriorated. The results of the study were published in the scientific journal Current Biology.
Researchers at the Finnish Institute for Health and Welfare (THL) have evaluated the impact of decriminalization policy in different settings. The new study reviews reports, peer-review articles, and critical response papers on the topic.
A new modeling study evaluating unfolding COVID-19 epidemics among different income countries reports that, in lower income countries, even if risk is reduced because populations are younger, this benefit is largely negated by limited health system capacity and closer inter-generational contact.
In a time of a documented decline of community and social connections, a large number of people who have needed assistance during the COVID-19 pandemic have found that help through community organizations, the government and their family, friends and neighbors, according to a newly released poll from the University of Rhode Island's Social Science Institute for Research, Education, and Policy.
Organizations led by more greedy CEOs—that is, CEOs that are driven by the pursuit of excessive or extraordinary material wealth—before the global financial crisis of 2008 suffered more severe consequences of that systemic shock. That is one of the main conclusions by a team of organization scientists from Antwerp and Tilburg based on a recent study that will be published in the Journal of Managem
The trajectory of the Covid-19 pandemic is continuing to shift away from major urban clusters in Europe and North America. As cases and hospitalizations subside in the northeastern U.S. and other hard-hit areas, they are climbing in some states, especially in the South and Southwest.
Today, stars fill the night sky. But when the universe was in its infancy, it contained no stars at all. And an international team of scientists is closer than ever to detecting, measuring and studying a signal from this era that has been traveling through the cosmos ever since that starless era ended some 13 billion years ago.
Looking deep into the universe, the NASA/ESA Hubble Space Telescope catches a passing glimpse of the numerous arm-like structures that sweep around this barred spiral galaxy, known as NGC 2608. Appearing as a slightly stretched, smaller version of our Milky Way, the peppered blue and red spiral arms are anchored together by the prominent horizontal central bar of the galaxy.
Anglers often lament how hard it can be to land a fish for dinner, but the tougher job usually falls to fisheries managers, who have set sustainable catch limits for the fishes we love to harvest.
Each installment of The Friendship Files features a conversation between The Atlantic ’s Julie Beck and two or more friends, exploring the history and significance of their relationship. This week she talks with two women in the U.K. who became best friends when they were pregnant, and with their daughters, who are best friends, too.

The PS5 ditches the straight lines for curved edges. (Sony/) Video game console releases don’t work like typical gadget announcements—they happen in slow motion. We heard the first details about Sony’s new PlayStation 5 more than a year ago, but this week we finally got our first look at the hardware, as well as a bunch of new games for the system. The case is a departure from the PS4’s current d
Invasive Eurasian water milfoil is flourishing in Wisconsin's lakes, sometimes outcompeting native plants and creating floating mats that cause problems for people, boats and property values. But new research shows that the benefits of using one type of historical lake-wide herbicide treatment may be outweighed by the costs to native aquatic plants.

University of Tsukuba and RIKEN researchers identified cells in the brain that can induce a hibernation-like state in mice or rats, species that do not naturally hibernate. In this state, oxygen consumption, body temperature, heart rate, and respiration were all lowered, and animals spontaneously recovered without any tissue damage. Inducing this state in humans could have several medical benefits
Blood vessels are the body's transportation system, carrying oxygen and nutrients to cells and whisking away waste. A research team led by a scientist at Tokyo University of Agriculture and Technology (TUAT) in Japan has discovered a mechanism by which the growth of these vessels' inner liner is stimulated, which may lead to therapeutics that could cut vessels off from tumors or help rebuild vesse

Every second of every day, countless biochemical reactions take place in our bodies' cells. The organization of this complex system is the result of billions of years of evolution, fine-tuning our functions since the first primordial organisms.
It’s not surprising that the fruit fly larva in the laboratory of Jimena Berni crawls across its large plate of agar in search of food. “A Drosophila larva is either eating or not eating, and if it’s not eating, it wants to eat,” she said. The surprise is that this larva can search for food at all. Owing to a suite of genetic tricks performed by Berni, it has no functional brain. In fact, the sys
Since the discovery of the double helix form of DNA and the hypothesis of DNA mutation induced by proton transfer more than 50 years ago, it has been recognized that proton transfer is crucial to many chemical and biological processes.

So let’s do a non-coronavirus post for the weekend. Over the years, I’ve sporadically reported on the (rather contentious) field of aging and its biochemical implications. Many readers will recall the results of the past few years that claim that infusion of young-animal plasma into aged animals seems to have many beneficial effects. Of course, this field is well stocked with controversy. Not eve
For thousands of years, the massive pelvis lay undisturbed at the bottom of the watery black pit. Approximately four feet across and weighing an estimated 80 pounds, it had once belonged to a giant ground sloth, an elephant-sized animal that roamed the ancient Americas alongside the saber-tooth cat and the woolly mammoth.
For decades, anthropologists have attempted to solve the mystery of what hominins—early ancestors of humans—ate to survive. The answer to this question can be found etched into the bones and teeth of hominins, but the conclusion is not always obvious.
State and federal executive orders have deemed seasonal and migrant farmworkers "essential." Yet, few protections have been granted to this population, which may be at higher risk of exposure to coronavirus, according to a policy brief by researchers at the University of Michigan School of Public Health.
