Bees are pollinators of many plants, but their diversity and density is declining. A team investigated their foraging behavior in agricultural landscapes. They found that honey bees prefer strawberry fields, even if flowering next to oilseed rape fields. Only when oilseed rape was in full bloom were fewer honey bees in the strawberries. Wild bees, on the other hand, consistently chose the strawber

One of the causes of breast cancer may be inflammation triggered by harmful bacteria suggest researchers. Scientists advise consuming natural yogurt, which contains beneficial bacteria which dampens inflammation and which is similar to the bacteria found in breastfeeding mothers. Their suggestion is that this bacteria is protective because breast feeding reduces the risk of breast cancer. The cons
Little organs within cells called lysosomes digest unwanted material. And like stomachs, they must be acidic to do so. If they aren't, cells stop growing. Researchers wanted to know why.
West Nile virus (WNV) inhibits autophagy — an essential system that digests or removes cellular constituents such as proteins — to induce the aggregation of proteins in infected cells, triggering cell death and brain inflammation (encephalitis), according to researchers.

A construction team is racing to build a new, 1,000-bed hospital in the next six days. As a virus spreads through one of the world's largest cities, no one is allowed to leave. When the count of the dead in Wuhan, China, reached 15 yesterday, government officials declared a quarantine. Trains and public transit came to a halt, and air travel was canceled. Residents were urged to stay at home, and
"Jumping genes"—bits of DNA that can move from one spot in the genome to another—are well-known for increasing genetic diversity over the long course of evolution. Now, new research at Washington University School of Medicine in St. Louis indicates that such genes, also called transposable elements, play another, more surprising role: stabilizing the 3-D folding patterns of the DNA molecule inside

The most common groups of soil protists behave exactly like Pac-Man: moving through the soil matrix, gobbling up bacteria according to a new article in Science Advances.
'This research is of interest to anyone who cares about political communications, and the results have clear implications for political campaign professionals,' said Haenschen. 'When you're choosing a candidate's visual identity, you need to consider how people perceive that font.'
Satellite Explosion AT&T-owned satellite TV company DirecTV has asked the Federal Communications Commission (FCC) for permission to "conduct emergency operations" to move a satellite that may be about to blow up, Space News reports . The fear is that a battery malfunction might cause the Boeing-built satellite to explode. An explosion in an already-busy orbit chock full of other satellites could
As of Friday, eight more Chinese cities have been placed on a travel lockdown — bringing the total to 12 — in an attempt to quarantine the coronavirus that appeared in Wuhan last month. As a result, public transportation has been suspended in towns that contain over half the population of China's Hubei Province, according to The New York Times . Now 35 million Hubei Province residents are effecti
Individuals with a history of early life adversity (ELA) are disproportionately prone to opioid addiction. A new UCI-led study reveals why. Published in Molecular Psychiatry, the study titled, "On the early life origins of vulnerability to opioid addiction," examines how early adversities interact with factors such as increased access to opioids to directly influence brain development and function

It's time to turn away from the World Economic Forum and its mass-polluting 'affiliates'. We need new, radical solutions • Payal Parekh is an international climate activist This week, among the private chalets and deep snow of Davos, the world's leading politicians and businesspeople have been spending their time at the World Economic Forum (WEF), and they've been talking about the climate crisis.
A new study suggests that significant early childhood exposure to traffic-related air pollution (TRAP) is associated with structural changes in the brain at the age of 12.
Halide perovskites have garnered attention because they're highly efficient at capturing energy in solar cells and efficient emitters in diodes. But researchers failed at making perovskite LEDs that emit blue light. UC Berkeley chemists succeeeded, but X-ray studies of the LED's structure show that it's very sensitive to temperature, humidity and chemical environment. Hence environmental and chemi
New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical fiber networks.
Community collaboration and high-resolution maps are key to effective flood risk management, according to a new study.

"The impacts of flooding continue to escalate in the US and around the
Living off Australia and New Guinea are at least nine species of walking sharks. Using fins as legs, they prowl coral reefs at low tide. The sharks are small, don't be frightened. None Natural selection takes time. According to the fossil record, sharks, for example, have been essentially the same for hundreds of millions of years. But something's up lately, and by "lately" we mean the last nine
University of California, Berkeley, scientists have created a blue light-emitting diode (LED) from a trendy new semiconductor material, halide perovskite, overcoming a major barrier to employing these cheap, easy-to-make materials in electronic devices.
New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical fiber networks. The team have demonstrated that multiple quantum patterns of twisted light can be transmitted across a conventional fiber link that, paradoxically, supports only o
Water issuing from an ordinary faucet tells a complex tale of its journey through a pipe. At high velocities, the faucet's gushing stream is turbulent: chaotic, disorderly—like the crash of ocean waves.
Tight control on the selectivity of nanoparticles' interaction with biological systems is paramount for the development of targeted therapies. However, the large number of tunable parameters makes it difficult to identify optimal design "sweet spots" without guiding principles. Here, we combine superselectivity theory with soft matter physics into a unified theoretical framework and we prove its
We develop a Bayesian hierarchical model to identify communities of time series. Fitting the model provides an end-to-end community detection algorithm that does not extract information as a sequence of point estimates but propagates uncertainties from the raw data to the community labels. Our approach naturally supports multiscale community detection and the selection of an optimal scale using m
Turbulent flows are not only everywhere, but every turbulent flow is the same at small scales. The extraordinary simplification engendered by this "small-scale universality" is a hallmark of turbulence theory. However, on the basis of the restrictive assumptions invoked by A. N. Kolmogorov to demonstrate this universality, it is widely thought that only idealized turbulent flows conform to this f
The environmental and chemical limits of life are two of the most central questions in astrobiology. Our understanding of life's boundaries has implications on the efficacy of biosignature identification in exoplanet atmospheres and in the solar system. The lipid bilayer membrane is one of the central prerequisites for life as we know it. Previous studies based on molecular dynamics simulations h
Plasmids are key vehicles of horizontal gene transfer (HGT), mobilizing antibiotic resistance, virulence, and other traits among bacterial populations. The environmental and genetic forces that drive plasmid transfer are poorly understood, however, due to the lack of definitive quantification coupled with genomic analysis. Here, we integrate conjugative phenotype with plasmid genotype to provide
Although many polymers exhibit excellent dielectric performance including high energy density with high efficiency at room temperature, their electric and dielectric performance deteriorates at high temperatures (~150°C). Here, we show that nanofillers at very low volume content in a high-temperature (high–glass transition temperature) semicrystalline dipolar polymer, poly(arylene ether urea), ca
Patch plays an important role in clinical medicine for its broad applications in tissue repair and regeneration. Here, inspired by the diverse adhesion, anti-adhesion, and responsive structural color phenomena in biological interfaces, we present a hybrid hydrogel film with an adhesive polydopamine (PDA) layer and an anti-adhesive poly(ethylene glycol) diacrylate (PEGDA) layer in an inverse opal
Protists are ubiquitous in soil, where they are key contributors to nutrient cycling and energy transfer. However, protists have received far less attention than other components of the soil microbiome. We used amplicon sequencing of soils from 180 locations across six continents to investigate the ecological preferences of protists and their functional contributions to belowground systems. We co
The global quantum network requires the distribution of entangled states over long distances, with substantial advances already demonstrated using polarization. While Hilbert spaces with higher dimensionality, e.g., spatial modes of light, allow higher information capacity per photon, such spatial mode entanglement transport requires custom multimode fiber and is limited by decoherence-induced mo
Achieving perovskite-based high–color purity blue-emitting light-emitting diodes (LEDs) is still challenging. Here, we report successful synthesis of a series of blue-emissive two-dimensional Ruddlesden-Popper phase single crystals and their high–color purity blue-emitting LED demonstrations. Although this approach successfully achieves a series of bandgap emissions based on the different layer t
Noninvasive blood glucose monitoring has been a long-standing dream in diabetes management. The use of Raman spectroscopy, with its molecular specificity, has been investigated in this regard over the past decade. Previous studies reported on glucose sensing based on indirect evidence such as statistical correlation to the reference glucose concentration. However, these claims fail to demonstrate
Layered honeycomb magnets are of interest as potential realizations of the Kitaev quantum spin liquid (KQSL), a quantum state with long-range spin entanglement and an exactly solvable Hamiltonian. Conventional magnetically ordered states are present for all currently known candidate materials, however, because non-Kitaev terms in the Hamiltonians obscure the Kitaev physics. Current experimental s
Controlling active colloidal particle swarms could enable useful microscopic functions in emerging applications at the interface of nanotechnology and robotics. Here, we present a computational study of controlling self-propelled colloidal particle propulsion speeds to cooperatively capture and transport cargo particles, which otherwise produce random dispersions. By sensing swarm and cargo coord
Poly(triazine imide) (PTI), a crystalline g-C 3 N 4 , hosting two-dimensional nanoporous structure with an electron density gap of 0.34 nm, is highly promising for high-temperature hydrogen sieving because of its high chemical and thermal robustness. Currently, layered PTI is synthesized in potentially unsafe vacuum ampules in milligram quantities. Here, we demonstrate a scalable and safe ambient

Almost 900 cases of the virus
The DNA molecule inside the nucleus of any human cell is more than six feet long. To fit into such a small space, it must fold into precise loops that also govern how genes are turned on or off. New research at Washington University School of Medicine in St. Louis indicates that 'jumping genes' play a surprising role in stabilizing the 3D folding patterns of the DNA molecule inside the cell's nucl
With these tips, you can dump out all those old corks and finally use that pan for its true purpose: making actual food.

They come with a high price tag and look stylish hanging in a kitchen, but are also durable and prized for conducting heat more
The three proteins teneurin, latrophilin and FLRT hold together and bring neighboring neurons into close contact, enabling the formation of synapses and the exchange of information between the cells. In the early phase of brain development, however, the interaction of the same proteins leads to the repulsion of migrating nerve cells, as researchers from the Max Planck Institute of Neurobiology and
US authorities said Friday they had granted permission to a TV provider to urgently lift a four-ton (3,600-kilogram) satellite to a so-called "graveyard orbit" over fears a battery fault may soon cause it to explode.
In the most recent issue of the academic journal Science, the case is made for a future where the materials and chemicals that make up the basis of our society and our economy are healthful rather than toxic, renewable rather than depleting, and degradable rather than persistent.
