(Press-News.org) Southwesterly wind shear has taken its toll on hurricane Humberto, and NASA's TRMM satellite noticed that in rainfall data.
When NASA's Tropical Rainfall Measuring Mission or TRMM satellite passed over Hurricane Humberto on September 12, 2013 at 1625 UTC/12:25 p.m. EDT the eye was no longer visible. An analysis derived from
TRMM Microwave Imager (TMI) and Precipitation Radar (PR) data showed that most of the precipitation with Humberto was located in the northwestern quadrant, pushed there by the strong southwesterly wind shear.
TRMM found that the most intense rain was falling at a rate of over 99 mm/~3.9 inches per hour near Humberto's center. TRMM PR also found that the highest storm towers were reaching heights of about 13.7 km/8.5 miles in the same area.

At 5 a.m. EDT/0900 UTC on Sept. 13, Hurricane Humberto's maximum sustained winds were near 75 mph/120 kph, but the National Hurricane Center expects weakening over the next two days. Humberto is expected to drop to tropical storm status late on Sept. 13. The center of Hurricane Humberto was located near latitude 24.4 north and longitude 30.2 west, about 705 miles/1,135 km northwest of the Cape Verde Islands. Humberto is moving toward the north-northwest near 12 mph/19 kph and it is expected to turn toward the west-northwest.
Humberto is expected to weaken to a tropical storm late on Sept. 13, and continue moving through the open waters of the Central North Atlantic Ocean over the next several days.

To touch the microcosmos
2013-09-13
WASHINGTON, D.C. Sept. 13, 2013 -- What if you could reach through a microscope to touch and feel the microscopic structures under the lens? In a breakthrough that may usher in a new era in the exploration of the worlds that are a million times smaller than human beings, researchers at Université Pierre et Marie Curie in France have unveiled a new technique that allows microscope users to manipulate samples using a technology known as "haptic optical tweezers."
Featured in the journal Review of Scientific Instruments, which is produced by AIP Publishing, the new technique ...
Diets low in polyunsaturated fatty acids may be a problem for youngsters
2013-09-13
In the first study to closely examine the polyunsaturated fatty acid (PUFA) intake among U.S. children under the age of 5, Sarah Keim, PhD, principal investigator in the Center for Biobehavioral Health at The Research Institute at Nationwide Children's Hospital, has found what might be a troubling deficit in the diet of many youngsters. The study, published online today by Maternal and Child Nutrition, used data on nearly 2500 children age 12 to 60 months from the U.S. National Health and Nutrition Examination Survey.
PUFAs are essential to human health. A proper ratio ...
Immune to aging
2013-09-13
This news release is available in German.
While ageing remains an inevitable fact of life, Max Planck researchers have discovered a microbe that stays forever young by rejuvenating every time it reproduces. The findings, published in Current Biology, provide fundamental insights into the mechanisms of aging.
In general, even symmetrically dividing microbes do not split into two exactly identical halves. Detailed investigations revealed that there are mechanisms in place that ensure that one half receives older, often defective, cell material, whereas the other ...
Novelty of eco-friendly bamboo garments lures consumers -- if the price is right, Baylor study shows
2013-09-13
Consumers who plan to buy eco-friendly bamboo apparel are attracted if the price is right, but their next consideration is the novelty of the product, according to a new study by Baylor University researchers.
Bamboo has been championed by many as friendly to the environment, although the Federal Trade Commission issued a 2009 consumer alert noting that some pollutants are released in production from bamboo stalks.
When it comes to product consumption in general, consumers are influenced by emotion, price, functionality, social image and curiosity, said lead researcher ...
UNC research points to promising treatment for macular degeneration
2013-09-13
CHAPEL HILL, N.C. – Researchers at the University of North Carolina School of Medicine have published new findings in the hunt for a better treatment for macular degeneration. In studies using mice, a class of drugs known as MDM2 inhibitors proved highly effective at regressing the abnormal blood vessels responsible for the vision loss associated with the disease.
"We believe we may have found an optimized treatment for macular degeneration," said senior study author Sai Chavala, MD, director of the Laboratory for Retinal Rehabilitation and assistant professor of Ophthalmology ...
'Red nugget' galaxies were hiding in plain sight
2013-09-13
In 2005 the Hubble Space Telescope spotted unusually small galaxies densely packed with red stars in the distant, young universe. They were nicknamed "red nuggets," not only because they are small and red but also their existence challenged current theories of galaxy formation, making them precious in astronomers' eyes.
Since no "red nuggets" were seen nearby, astronomers wondered why they had disappeared over time. New research shows that they didn't disappear completely. In fact, they were simply hidden within the data of previous surveys.
Astronomers now realize ...

Older drinkers may experience fewer hangovers due to less intense drinking
While hangovers may be a source of humor, their effects can be debilitating, costly, and even dangerous.
A new study of hangovers across the lifespan has found that the tendency to experience hangovers decreases as age increases.

Sober drinking knowledge often fails 'in the moment' of intoxication
Approximately one-third of all fatal crashes each year in the U.S. involve an alcohol-impaired driver.
New research compares individuals' perceived dangerousness of driving after drinking while intoxicated with those perceptions while sober.
