(Press-News.org) Tropical Cyclone Nilofar was closing in on the border between Pakistan and northwestern India on Oct. 30 when NASA's Terra satellite passed overhead from space. Wind shear continued to affect the storm making it appear more like a comet with a tail, than a tropical cyclone.
The MODIS or Moderate Resolution Imaging Spectroradiometer instrument that flies aboard NASA's Terra satellite captured a visible image of Nilofar on Oct. 30 at 06:35 UTC (2:35 a.m. EDT). Nilofar was still being affected by southwesterly wind shear, which was blowing the clouds and showers to the northeast. In the MODIS image, thunderstorms surrounded the center of the storm making it look like the core of a comet. Wind shear was stretching out clouds and showers to the northeast of the center, making it look like a comet's tail. Those clouds over northwestern India were already bringing rain along with gusty winds to the region. Nilofar was already causing rough surf to coastlines from India and Pakistan west to Oman.
The Joint Typhoon Warning Center noted that microwave satellite imagery showed a ragged eye, but the low-level center of circulation appears to be "unraveling."
The wind shear has been weakening Nilofar, and by Thursday, Oct. 30 at 900 UTC (5 a.m. EDT) maximum sustained winds had dropped below hurricane-strength to 50 knots (57.5 mph/92.6 kph) and are expected to weaken the storm to a depression by November 1. Nilofar was located near 20.2 north latitude and 64.3 east longitude, about 294 nautical miles east of Masirah Island. It was moving to the northeast at 5 knots (5.7 mph/9.2 kph).
On Oct. 30, the India Meteorological Department's Regionalized Specialized Meteorological Centre (RSMC) forecast called for Nilofar to move northeastward and weaken into a depression over northeast Arabian Sea off the north Gujarat coast late (local time) on Oct. 31.
The RSMC warned that Nilofar will bring "moderate rainfall at most places with isolated heavy to very heavy falls over Kutch and coastal districts of Saurashtra during next two days. Light to moderate rainfall at many places with isolated heavy falls would occur over remaining districts of Saurashtra, the north Gujarat region and southwest Rajasthan during the same period." Squally winds reaching 40 to 50 kph (24.8 mph to 31.0 mph) are expected off the Gujarat coast on Oct. 31.

Nilofar is expected to become a depression by Nov. 1 before making landfall near the border of Pakistan and northwestern India.

Clinical practice guidelines address multimodality treatment for esophageal cancer
2014-10-30
Chicago, October 30, 2014 – The Society of Thoracic Surgeons (STS) has released new clinical practice guidelines for treating cancer of the esophagus and gastroesophageal junction (area where the esophagus meets the stomach).
The guidelines, published in the November 2014 issue of The Annals of Thoracic Surgery, include nine evidence-based recommendations that address issues related to multimodality care, including neoadjuvant therapy (chemotherapy and radiation therapy given prior to surgery). The goal of this therapy is to reduce the extent of cancer before an ...
Molecular tumor markers could reveal new therapeutic targets for lung cancer treatment
2014-10-30
Chicago, October 30, 2014—Analysis of 607 small cell lung cancer (SCLC) lung tumors and neuroendocrine tumors (NET) identified common molecular markers among both groups that could reveal new therapeutic targets for patients with similar types of lung cancer, according to research presented today at the 2014 Chicago Multidisciplinary Symposium in Thoracic Oncology. The Symposium is sponsored by the American Society of Clinical Oncology (ASCO), the American Society for Radiation Oncology (ASTRO), the International Association for the Study of Lung Cancer (IASLC) and ...
Young adults ages 18 to 26 should be viewed as separate subpopulation in policy and research
2014-10-30
WASHINGTON – Young adults ages 18-26 should be viewed as a separate subpopulation in policy and research, because they are in a critical period of development when successes or failures could strongly affect the trajectories of their lives, says a new report from the Institute of Medicine and National Research Council. The committee that wrote the report found that young adults' brains and behaviors continue maturing into their 20s, and they face greater challenges achieving independence than their predecessors did, have lengthened pathways into adulthood, and are ...
University of Tennessee study finds saving lonely species is important for the environment
2014-10-30
The lemur, Javan rhino and Santa Cruz kangaroo rat are all lonesome animals. As endemic species, they live in habitats restricted to a particular area due to climate change, urban development or other occurrences.
Endemic species are often endangered, and a University of Tennessee, Knoxville, study finds that saving them is more important to biodiversity than previously thought.
Joe Bailey, associate professor in the Department of Ecology and Evolutionary Biology, and his colleagues from the University of Tasmania in Australia looked at endemic eucalyptus found in ...

Toddlers copy their peers to fit in, but apes don't
2014-10-30
From the playground to the board room, people often follow, or conform, to the behavior of those around them as a way of fitting in. New research shows that this behavioral conformity appears early in human children, but isn't evidenced by apes like chimpanzees and orangutans.
"Conformity is a very basic feature of human sociality. It retains in- and out-groups, it helps groups coordinate and it stabilizes cultural diversity, one of the hallmark characteristics of the human species," says psychological scientist and lead researcher Daniel Haun of the Max Planck Institute ...
