Tropical Depression 10E has formed in the Eastern Pacific Ocean and the GOES-West satellite caught its formation far from the Baja Peninsula.
NOAA's GOES-West satellite provided a visible image of the newly developed depression on August 21, 2019. The system appears more organized and circular on satellite imagery. In addition, An early morning scatterometer instrument overpass that looks at winds in a system, showed a nearly closed surface low pressure area.
NASA's Aqua satellite provided a view of newly formed Tropical Storm Chantal in the North Atlantic Ocean. The image revealed that the storm formed despite being battered by outside winds.
The third named storm of the Atlantic Ocean hurricane season formed around 11 p.m. EDT on Aug. 20, far from land and almost 500 miles southeast of Halifax, Nova Scotia, Canada.
WASHINGTON - Over two million Muslim travelers just finished the annual religious pilgrimage to Mecca, Saudi Arabia, traveling during some of the country's hottest weather. New research finds pilgrims in future summers may have to endure heat and humidity extreme enough to endanger their health. The results can help inform policies that would make the trip safer for the several million people who make the pilgrimage each year, according to the study's authors.
TAMPA, Fla. - A personalized approach to cancer treatment has become more common over the last several decades, with numerous targeted drugs approved to treat particular tumor types with specific mutations or patterns. However, this same personalized strategy has not translated to radiation therapy, and a one-size-fits-all approach for most patients is still common practice.
In late August 2011, a magnitude 5.8 earthquake - the strongest east of the Mississippi since 1944 - shook Washington, D.C., with such force that it cracked the Washington Monument and damaged the National Cathedral.
On the sixth floor of the neonatal intensive care unit (NICU) at Children's National in Washington, D.C., staff felt the hospital swaying from side to side.
As major wildfires increase in Canada's North, boreal forests that have acted as carbon sinks for millennia are becoming sources of atmospheric carbon, potentially contributing to the greenhouse effect.
Life over the last half century has been pretty good for populations of Svalbard barnacle geese. A hunting ban implemented in the 1950s in their overwintering area in Scotland has led to explosive population growth -- from roughly 2800 birds in 1960 to more than 40000 birds today.
But what will happen to these birds and others like them, which migrate to Arctic nesting grounds, as the climate grows warmer?
Adults carrying a gene associated with a higher risk of Alzheimer's disease had a harder time accessing recently acquired knowledge, even though they didn't show any symptoms of memory problems, according to findings published in a joint Baycrest-University of Oxford study.
Researchers found that older adults carrying a specific strain of the gene, apolipoprotein E4, otherwise known as APOE4, weren't able to tap into information they had just learned to assist them on a listening test.
Increasing atmospheric CO2 concentration is the leading cause of greenhouse effects and global warming. Notably, rapid climate warming can, in turn, either increase or decrease land carbon uptake, leading to negative or positive carbon cycle-climate change feedback, respectively.
Scientists previously did not understand what caused the direction of carbon-climate feedback, making it difficult to predict future climate warming.
Researchers from The Irish Longitudinal Study on Ageing (TILDA) at Trinity College Dublin have shown in the largest study to date that lower levels of specific dietary vitamins and antioxidants are associated with frailty.
Ion beams are often used today in cancer treatment: this involves electrically charged atoms being fired at the tumour to destroy cancer cells. Although, it's not actually the ions themselves that cause the decisive damage. When ions penetrate through solid material, they can share part of their energy with many individual electrons, which then continue to move at relatively low speed - and it is precisely these electrons that then destroy the DNA of the cancer cells.
Clear evidence that higher levels of physical activity - regardless of intensity - are associated with a lower risk of early death in middle aged and older people, is published by The BMJ today.
The findings also show that being sedentary, for example sitting still, for 9.5 hours or more a day (excluding sleeping time) is associated with an increased risk of death.
Previous studies have repeatedly suggested that sedentary behaviour is bad and physical activity is good for health and long life.
A multi-national team of researchers, including authors from the National Institute for Health Research (NIHR) Leicester Biomedical Research Centre (BRC), have produced clear evidence that higher levels of physical activity - regardless of intensity - are associated with a lower risk of early death in middle aged and older people.
The findings, published in The BMJ today, also show that being sedentary, for example sitting, for 9.5 hours or more a day (excluding sleeping time) is associated with an increased risk of death.
Toxoplasma gondii is a microbial parasite that infect humans and complete its full life cycle only in cats. New research published August 20 in the open-access journal PLOS Biology shows why: the sexual phase of the parasite's life cycle requires linoleic acid, a nutrient/lipid found at uniquely high levels in the felines, because cats lack a key enzyme for breaking it down.
As medicine becomes both bigger and more personalized, the need for massive databases of patient records, such as the 1 million person All of Us Research Program, become increasingly essential to fueling both new discoveries and translational treatments.
