Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
Some menopausal women experience night sweats and hot flashes. Hormone replacement therapy is the standard of care for menopausal patients, but not all women are good candidates for it and then some simply don't trust science and medicine; they buy organic food, worry about cellphone radiation, and have read Facebook posts claiming hormone replacement therapy puts them at increased risk for breast cancer and cardiovascular disease.Hops are labeled a natural alternative to medicine because they contain phytoestrogens. Phytoestrogens are plant-based compounds that mimic the action of female sex hormones, whose deficiency is considered to be the root of symptoms often felt by women in menopause.
The Scream is not one work of art but several; two paintings, two pastels, several lithographic prints and a few drawings and sketches. Edvard Munch was a practical artist so if the check cleared he would make another.His original Tempera on Cardboard is the most well-known version and can be found in Oslo’s National Gallery (Nasjonalmuseet) while his least liked version is crayon on cardboard. After the first was sold he made another two years later, in pastel on cardboard, and it is a lot less gloomy than the original. Probably because of the money he was getting. He then painted another Tempera on Cardboard in 1910 because the others had sold.
The biggest cause of bee die-offs is just random luck. For as long as bee numbers have been reported there have been reports of sudden, large-scale die-offs. Nature is out to kill them like it is all of us. Yet more recently, it has been found that we can help bees make their own luck. Pesticides wipe out varroa mites, the greatest enemy bees have.
Though coronavirus is a new name for much of the world, microbiologists have worried about it for half a century. It is in the same family as the common cold virus but with the right mutation it can be deadly to those with risk factors for respiratory diseases because it is common like the common cold.To microbiologists, the world is filled with pathogens so predicting the next plague when nature is always out to kill us can verge on paranoia; instead we are fortunate most new crises never happen. Let's hope that worry about global spread of the multi-resistant pathogen Stenotrophomonas maltophilia fizzles out also.
A new paper has implicated a physiologic mechanism in vegetation as a cause for Arctic warming.The "greenhouse effect" is well-known by now, water vapor that plants emit during photosynthesis serves to lower land surface temperature, similar watering the yard on a hot day, but it can lead to a rise in air temperature. The new paper finds that the Arctic temperature rises when the moisture released by plants is reduced due to the increase of carbon dioxide (CO2 ) in the atmosphere. The increase in atmospheric CO2 concentration closes the pores (stomata) of plants in high-latitude areas and reduces their transpiration, which they find ultimately accelerates Arctic warming.
When states and nations began to implement forced lockdowns to combat COVID-19, the SARS-CoV-2 coronavirus that has now killed 20,000 more people than the flu did two years ago, there was relatively little mention of mental health. For those who wanted to stay home and learn to bake bread, it was a paid vacation, but for those more susceptible to psychological stress it is a risky time.
Anxiety-prone people can blame serotonin cleanup proteins gone awry in their amygdala, according to research in marmosets recently published in JNeurosci. Targeting the amygdala with anti-anxiety medication could provide quicker relief.
The same event or set of life circumstances could send one person into the depths of anxiety or despair while leaving another unaffected. This distinction, called trait anxiety, arises from the proteins involved in serotonin signaling, a neurotransmitter implicated in anxiety and depression.
In 2000, vaccines led to the measles virus being declared eliminated from the United States yet in 2019 there were 1,282 confirmed cases in 31 states - the greatest number reported since 1992. Unsurprisingly, nearly three-fourths originated from New York which, along with the west coast, has long been a hotbed for vaccine denial. And the cases occurred in people not vaccinated against measles.
The last group most of the world wants to hear from right now is a lab in Wuhan, but if their microwave air plasma thruster is more real than their claims of having a certified BSL-2 lab studying coronavirus, there could be a great deal of interest in the future. Like solids, gases, and liquids, plasma is fourth state of matter found naturally in places like the sun's surface and Earth's lightning. The Institute of Technological Sciences at Wuhan Universitysay they have created a plasma jet by compressing air into high pressures and using a microwave to ionize the pressurized air stream.
Though slavery is still invoked in the United States of America, it is ironically because it was relatively rare compared to the rest of the continent. Only 4 percent of African slaves brought by Europeans and other Africans were brought to what is now the U.S, and importation was banned by President Thomas Jefferson in 1808. The remaining 96 percent went to Latin America and there is no benefit to invoking slavery when so many have not only slaves as ancestors, but also the colonizers who brought them.Bringing in a huge population of slaves left behind a science story, and that story is filled out a little by three individuals found within a mass burial site from the 16th century at San José de los Naturales Royal Hospital in Mexico City.
Collective layoffs of large groups of workers have been common during the Coronavirus Pandemic of 2020.
A new paper might inform possible impacts because it analyzed 556 collective layoffs announced between December 2018 and November 2019 across different industries that involved more than 250,000 employees. They wanted to see what collective layoff decisions had on the firms that initiated them.
The termination of employment, particularly of large numbers of people, typically evokes negative connotations. While the effect on individuals is obvious they found that layoff announcements have negative effects on companies.
If you are an artist, you will need a much different bionic arm than a soldier and a new waypoint on the road to interchangeable bionics has been developed. In July 2019, the Clinical Laboratory for Bionic Limb Reconstruction at MedUni Vienna's Department of Surgery implanted sensors in three male patients following nerve transfers, to transmit biosignals for wireless control of bionic prostheses.
