NASA sees new tropical storm threatening Mauritius and Reunion Islands
2014-12-01
(Press-News.org) NASA's Terra satellite passed over Tropical Cyclone 02S after it formed in the Southern Indian Ocean on Nov. 28. An image from Terra showed that the new tropical storm is close to Mauritius and Reunion Islands.
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a visible image of newborn Tropical Cyclone 02S northeast of the islands of Mauritius and Reunion. The MODIS image showed that thunderstorms were mostly west of the low-level center of circulation and bands of thunderstorms were wrapping into the center. A microwave image also showed that wind shear pushed the bulk of the deep convection and strong thunderstorms west of the defined low-level center.
On Nov. 28 at 1500 UTC (10 a.m. EST), Tropical Cyclone 02S had maximum sustained winds near 35 knots (40 mph/64 kph). It was centered near 16.6 South longitude and 61.2 East latitude, about 430 nautical miles (494.8 miles/796.4 kilometers) northeast of St. Denis. Tropical Cyclone 02S was moving to the southwest at 14 knots (16.1 mph/25.9 kph).
A sub-tropical ridge or elongated area of high pressure located to the east-southeast of the tropical storm will continue steering it to the southwest. Thereafter a mid-latitude trough (elongated area) of low pressure will steer it southward.
Over the next couple of days, Mauritius and Rodrigues Islands are expected to receive gusty winds, showers and rough seas as Tropical Cyclone 02S moves closer. Mauritius Meteorological Service updates can be found at: http://metservice.intnet.mu/warning-bulletin-special-weather.php
In three days, vertical wind shear is expected to increase and the tropical cyclone is forecast to move into cooler waters. Those two factors will weaken the storm. According to the Mauritius Meteorological Services, the tropical cyclone will pass close to Mauritius by Sunday when it will likely be a depression.

This news release is available in German. Humans don't like being alone, and their genes are no different. Together we are stronger, and the two versions of a gene - one from each parent - need each other. Scientists at the Max Planck Institute for Molecular Genetics in Berlin have analysed the genetic makeup of several hundred people and decoded the genetic information on the two sets of chromosomes separately. In this relatively small group alone they found millions of different gene forms. The results also show that genetic mutations do not occur randomly in the ...

Two physicists from the University of Warwick have taken to the kitchen to explain the complexity surrounding what they say is one of the last big mysteries in polymer physics.
As a way of demonstrating the complicated shapes that ring-shaped polymers can adopt, the researchers have created a brand new type of ring-shaped pasta, dubbed "anelloni" (anello being the Italian word for "ring"), which they've exclusively unveiled in this month's Physics World.
With just 2 eggs and 200 g of plain flour, Davide Michieletto and Matthew S Turner have created large loops of pasta ...

Peter Friedl, M.D., Ph.D., professor of genitourinary medical oncology at The University of Texas MD Anderson Cancer Center, has received one of Italy's top scientific awards for his work in imaging and cancer growth, metastasis and therapy response.
Friedl was named a recipient of the 13th annual City of Florence Prize in Molecular Sciences. Previous recipients include such scientific luminaries as AIDS research pioneer Robert C. Gallo. M.D., human genome sequencing expert J. Craig Venter, Ph.D., and Nobel laureates Robert Hubert, Ph.D. and Ada Yonath, Ph.D. Friedl received ...

Replenishing the supply of a molecule that normally activates cannabinoid receptors in the brain could relieve mood and anxiety disorders and enable some people to quit using marijuana, a Vanderbilt University study suggests.
Cannabinoid receptors are normally activated by compounds in the brain called endocannabinoids, the most abundant of which is 2-AG. They also are "turned on" by the active ingredient in marijuana.
Sachin Patel, M.D., Ph.D., and his colleagues developed a genetically modified mouse with impaired ability to produce 2-AG in the brain. The mice exhibited ...

This research is being carried out under the auspices of MAGDRIVE, a European research project coordinated by Professor José Luis Pérez Díaz, from the UC3M Instituto Pedro San Juan de Lastanosa, in which seven European entities participate. It consists of the development of a magnetic gear reducer, that is, a mechanism that transforms speed from an input axle to another in an output axle (as in a bicycle chain mechanism or the gearbox of an automobile). But in this case, unlike a conventional gear reducer, this transmission is produced without contact between ...

Astronomers have measured the passing of a super-Earth in front of a bright, nearby Sun-like star using a ground-based telescope for the first time. The transit of the exoplanet 55 Cancri e is the shallowest detected from the ground yet. Since detecting a transit is the first step in analyzing a planet's atmosphere, this success bodes well for characterizing the many small planets that upcoming space missions are expected to discover in the next few years.
The international research team used the 2.5-meter Nordic Optical Telescope on the island of La Palma, Spain, a moderate-sized ...

December 1, 2014 - A study using intricate fiber dissection techniques provides new insights into the deep anatomy of the human brainstem--and helps to define "safe entry zones" for neurosurgeons performing brainstem surgery, according to a special article published in Operative Neurosurgery, a quarterly supplement to Neurosurgery, official journal of the Congress of Neurological Surgeons. These publications are published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Neurosurgeons Dr. Kaan Yagmurlu and Dr. Albert L. Rhoton, Jr, of University of Florida, ...

Philadelphia, PA, December 1, 2014 - Panic disorder is a severe form of anxiety in which the affected individual feels an abrupt onset of fear, often accompanied by profound physical symptoms of discomfort. Scientists have known from studying twins that genes contribute to the risk of panic disorder, but very little is known about which specific genes are involved.
Two of the most common and terrifying symptoms of this severe anxiety are a sense of shortness of breath and feelings of suffocation. Studies have shown that breathing air that has increased levels of carbon ...

Mate choice is often the most important decision in the lives of humans and animals. Scientists at the Konrad Lorenz Institute of Ethology at the Vetmeduni Vienna have found the first evidence that birds may choose their mate through odor. They published their findings in Nature's Scientific Reports.
It has long been understood that reproducing with close relatives may have profoundly negative effects on offspring. It is therefore not surprising that biologists have discovered in some species that breeding individuals have evolved ways to detect their genetic similarity ...

Current data bases hold information on thousands of molecules--including drugs, natural substances, and chemical agents found in the environment-- that are associated with diseases, either because they have adverse effects or exert a therapeutic action. Using this information, gathered over many years and available in data bases, scientists headed by ICREA researcher Patrick Aloy at the Institute for Research in Biomedicine (IRB Barcelona) have devised a predictive model that allows them to associate chemical fragments with positive or negative effects in 20% of human ...
