To Keep Campuses Safe, Some Colleges To Test Students For Coronavirus Twice A Week

Anyone who has spent more than a few minutes watching some of the more partisan “news” networks lurking in the bowels of cable television is aware that America has grown more polarized in recent years. What’s not so certain is why. In a paper published online March 27 in the Proceedings of the National Academy of Sciences PNAS , a team of researchers at Stanford has devised a mathematical model that helps demonstrate what’s behind the growing rift. The prevailing sociological theory, known as homophily, is that like seeks like. Those who have similar opinions tend to aggregate together and reinforce opinions that grow more divergent from the center over time. This is the echo chamber model that would seem to gain validation in the era of talk radio, cable news and the Internet. According to this theory, we are polarized precisely because we have greater ability to choose our social networks and news sources.

February 11, A new study on ice cores shows that reductions in sea ice in the Arctic in the period between , years ago led to major climate events. During this period, Greenland temperatures rose by as much as 16 degrees Celsius. From this they determined that sea ice changes were massively significant in past climate change events in the North Atlantic.

In fact, this week’s PNAS had a paper on a study showing that online dating, (​surprise!), allegedly leads to happier marriages. Not only was.

It is the expression and active agency of a political order and moral economy in which capitalist market forces are treated as unassailable nature. An integral element of that moral economy is displacement of the critique of the invidious outcomes produced by capitalist class power onto equally naturalized categories of ascriptive identity that sort us into groups supposedly defined by what we essentially are rather than what we do.

Online Dating Study: Is PNAS Getting Cozy with eHarmony?

The study focused on a region of the brain called the ventromedial hypothalamus VMH and found that the removal of the metabotropic glutamate receptor 5 mGluR5 in that area caused estrogen to reduce the activity of neurons important for glycemic control, leading to insulin resistance and glucose intolerance. These effects were opposite to the increased neuronal activity and enhanced glucose metabolism observed in mice with the receptor following estrogen delivery.

The paradoxical outcome on glucose metabolism was seen in female, but not male, mice. Prior research by others had indicated that the VMH region of the brain plays a role in managing appropriate levels of glucose production in the liver and utilization of circulating glucose by cells and tissues. Within the VMH, steroidogenic factor 1 SF1 neurons are responsible for helping to regulate glucose as well as lipid levels, e. However, less was known about exactly how the VMH regulates glucose metabolism.

Author contributions: J. Date palm Phoenix dactylifera L. We use whole-genome sequence data from a large sample of P. This species is cultivated widely in the Middle East and North Africa, and previous population genetic studies have shown genetic differentiation between these regions.

We investigated the evolutionary history of P. Our results indicate that the North African population has mixed ancestry with components from Middle Eastern P. Introgressive hybridization is supported by tests of admixture, reduced subdivision between North African date palm and P.

Officials at the U. Centers for Disease Control and Prevention and epidemic experts from universities around the world conferred last month about what might happen if the new coronavirus gained a foothold in the United States. How many people might die? How many would be infected and need hospitalization? The assumptions, reviewed by The New York Times, were shared with about 50 expert teams to model how the virus could tear through the population — and what might stop it. The C.

Translated into absolute numbers by independent experts using simple models of how viruses spread, the worst-case figures would be staggering if no actions were taken to slow transmission. Between million and million people in the United States could be infected over the course of the epidemic, according to a projection that encompasses the range of the four scenarios. That could last months or even over a year, with infections concentrated in shorter periods, staggered across time in different communities, experts said.

As many as , to 1. And, the calculations based on the C. Fewer than a tenth of those are for people who are critically ill. The assumptions fueling those scenarios are mitigated by the fact that cities, states, businesses and individuals are beginning to take steps to slow transmission, even if some are acting less aggressively than others. Those actions include testing for the virus, tracing contacts, and reducing human interactions by stopping mass gatherings, working from home and curbing travel.

Global declines in insects have sparked wide interest among scientists, politicians, and the general public. Loss of insect diversity and abundance is expected to provoke cascading effects on food webs and to jeopardize ecosystem services. Our understanding of the extent and underlying causes of this decline is based on the abundance of single species or taxonomic groups only, rather than changes in insect biomass which is more relevant for ecological functioning.

Here, we used a standardized protocol to measure total insect biomass using Malaise traps, deployed over 27 years in 63 nature protection areas in Germany 96 unique location-year combinations to infer on the status and trend of local entomofauna. We show that this decline is apparent regardless of habitat type, while changes in weather, land use, and habitat characteristics cannot explain this overall decline.

This yet unrecognized loss of insect biomass must be taken into account in evaluating declines in abundance of species depending on insects as a food source, and ecosystem functioning in the European landscape.

Rechargeable batteries are notoriously difficult to examine nondestructively, and the obscurity of many failure modes provides a strong motivation for developing efficient and detailed diagnostic techniques that can provide information during realistic operating conditions.

In-situ NMR spectroscopy has become a powerful technique for the study of electrochemical processes, but has mostly been limited to laboratory cells. One significant challenge to applying this method to commercial cells has been that the radiofrequency, required for NMR excitation and detection, cannot easily penetrate the battery casing due to the skin depth. This article demonstrates that it is possible to use the battery cell as a resonator in a tuned circuit, thereby allowing signals to be excited inside the cell, and for them to subsequently be detected via the resonant circuit.

Employing this approach, 7 Li NMR signals from the electrolyte, as well as from intercalated and plated metallic lithium in a multilayer rolled commercial pouch cell battery were obtained. Therefore, it is anticipated that critical nondestructive device characterization can be performed with this technique in realistic and even commercial cell designs.
