In academic publishing , a scientific journal is a periodical publication intended to further the progress of science , usually by reporting new research. Articles in scientific journals are mostly written by active scientists such as students, researchers and professors instead of professional journalists. There are thousands of scientific journals in publication, and many more have been published at various points in the past see list of scientific journals. Most journals are highly specialized, although some of the oldest journals such as Nature publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that have been peer reviewed , in an attempt to ensure that articles meet the journal’s standards of quality, and scientific validity. Although scientific journals are superficially similar to professional magazines , they are actually quite different. Issues of a scientific journal are rarely read casually, as one would read a magazine. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results.

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.

Black babies in the US are up to three times more likely to die in the days and weeks following their births compared to white babies, a new study finds. But their survival odds vary drastically depending on who is in charge of their medical care. When black babies were cared for by black doctors, their mortality rate fell by 39 to 58 percent, according to George Mason University research.
The damning report suggests that black doctors take better care of black babies and are just as capable when looking after white newborns – yet the overwhelming majority of doctors are white, heightening the challenge of improving care for black infants in the US. An analysis of data on 1. The state of maternal-fetal mortality in the US is dismal, statistically speaking, when compared to other comparably wealthy nations. In – the most recent year for which there is complete data – 3.
Far more babies are born in poor health in the US than in the UK or Scandinavian countries, making their survival odds lower from their first breaths. And black families lose their newborn children at far higher rates than do white families in the US. Birth weight is a key indicator of a baby’s health, and black babies are far more likely to be born underweight compared to white babies. Between and ,

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.

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 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.

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.

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. Nuclear Magnetic Resonance NMR spectroscopy has proven to be a powerful technique for analyzing the properties of a broad array of materials under a wide range of physical conditions.
Using radio frequency rf excitation, NMR signals from solids, liquids, and even gases can be obtained 1 , 2 , 3. In situ NMR spectroscopy of electrochemical cells has become a highly active research area 4 , 5 , 6.
