(Press-News.org) The AIRS instrument aboard NASA's Aqua satellite provided a look at what's happening under Tropical Depression Genevieve's clouds using infrared light, and it appears that thunderstorms are bubbling up again.
A false-colored infrared image created at NASA's Jet Propulsion Laboratory in Pasadena California used data from the Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite. The AIRS data showed powerful thunderstorms re-developed around Genevieve's center on August 5 at 8:35 a.m. EDT. That's an indication that there's some punch left in the storm, and that punch could help it strengthen, according to the Central Pacific Hurricane Center (CPHC).
In the August 5 discussion about Genevieve, the CPHC noted "Genevieve has continued to present a bursting pattern during the overnight hours...with the low level circulation center estimated to be under the southeastern portion of an area of very cold cloud tops."
At 11 a.m. EDT (1500 UTC) today, Tuesday, August 5, Genevieve's maximum sustained winds were near 35 mph (55 kph). The NOAA Central Pacific Hurricane Center notes that gradual strengthening is forecast today through Wednesday, and Genevieve may become a tropical storm later today.
The center of tropical depression Genevieve was located near latitude 11.1 north, longitude 171.1 west. That's about 1,120 miles (1,805 km) southwest of Honolulu, Hawaii and 400 miles (645 km) south-southwest of Johnston Island. The depression is moving toward the west-northwest near 14 mph (22 kph) and this motion is expected to continue today through Wednesday. The estimated minimum central pressure is 1005 millibars.
NOAA's CPHC calls for slow intensification over the next couple of days as the storm continues to track in a westerly direction. Genevieve is expected to cross the International Date Line in a couple of days and when it does the forecast management of the storm would covered by the Joint Typhoon Warning Center.

3-in-1 optical skin cancer probe
2014-08-05
WASHINGTON, D.C., August 5, 2014 – As thousands of vacationers hit the beach this summer, many of them will expose their unprotected bare limbs to direct UV sunlight, potentially putting them at risk of skin cancer later in life. To fight back, scientists can also turn to light, designing optical devices that may detect cancerous skin lesions early on, leading to better treatment outcomes and ultimately saving lives.
Researchers from the University of Texas at Austin's Cockrell School of Engineering have now developed a probe that combines into one device three unique ...
Diamond defect interior design
2014-08-05
WASHINGTON, D.C., August 5, 2014 – By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale sensors. They describe their technique in a paper published in the journal Applied Physics Letters, from AIP Publishing.
David Awschalom, a physicist at the Institute for Molecular Engineering at the University of Chicago, and his colleagues study a technologically useful diamond defect called a nitrogen vacancy (NV) center. NV ...
University of Minnesota researcher finds cooling effect in warming Arctic lakes
2014-08-05
Scientists have known for a while that warming global temperatures are causing Arctic lakes to release methane, a potent greenhouse gas that leads to even more warming. In a new study published in the journal Nature, a team of researchers including U of M researcher Jacques Finlay, found that Siberian lakes have actually pulled more greenhouse gasses from the atmosphere than they have released into it since the last Ice Age, causing an overall slight cooling effect.
Permafrost, especially that in the Siberian Arctic, contains significant amounts of all organic carbon ...
UH Case Medical Center study validates new approach to high blood pressure
2014-08-05
CLEVELAND – It truly could be mind over matter after all.
University Hospitals Case Medical Center's Richard Josephson, MD, recently released trial results in a study published in Psychosomatic Medicine that discusses mindfulness-based stress reduction (MBSR) for hypertension.
Nearly 60 million adults in the United States have high blood pressure in the pre-hypertensive range. Current treatment guidelines recommend lifestyle changes such as diet, exercise and overall weight loss.
According to the new study, these changes can be dramatically augmented by MBSR as the ...
The interaction of climate change, fire, and forests in the US
2014-08-05
A special section of the September issue of Forest Ecology and Management, available online now, assesses the interactions among fire, climate change, and forests for five major regions of the United States.
The editors of the section—Drs. Chelcy Miniat from the U.S. Forest Service, Monique Rocca from Colorado State University, and Robert Mitchell (now deceased) from the Joseph W. Jones Ecological Research Center—started the project by organizing teams of scientists from the Forest Service and universities to provide scientific input into the third National Climate ...
NASA satellite sees a somewhat lopsided Typhoon Halong
2014-08-05
Infrared satellite imagery from NASA shows bands of powerful thunderstorms around Typhoon Halong's center, southern and eastern quadrants, while the northern quadrant is lacking in them. Typhoon Halong appears somewhat lopsided on satellite imagery because thunderstorm development in the northern side of the storm is being inhibited.
When NASA's Aqua satellite passed over Typhoon Halong on Aug. 4 at 12:47 a.m. EDT, the Atmospheric Infrared Sounder (AIRS) instrument aboard provided infrared data on the cloud top temperatures of Typhoon Halong. AIRS data showed powerful ...
Butterflies could hold key to probes that repair genes
2014-08-05
CLEMSON, S.C. — New discoveries about how butterflies feed could help engineers develop tiny probes that siphon liquid out of single cells for a wide range of medical tests and treatments, according to Clemson University researchers.
The National Science Foundation recently awarded the project $696,514. It was the foundation's third grant to the project, bringing the total since 2009 to more than $3 million.
butterflyThe research has brought together Clemson's materials scientists and biologists who have been focusing on the proboscis, the mouthpart that many insects ...
PET/CT using FDG-labeled leucocytes may detect infection in acute pancreatitis patients
2014-08-05
Reston, Va. (August 5, 2014) – A new study diagnosing infection in patients with pancreatic fluid collections may swiftly and accurately rule out active infection in the body. As reported in the August issue of The Journal of Nuclear Medicine, this treatment may assist in bringing nuclear medicine to the forefront of clinical management.
Acute pancreatitis (AP) is a sudden inflammation of the pancreas. It can have severe complications and high mortality despite treatment. While mild cases of AP are often successfully treated with conservative measures, such as nil per ...
Kaiser Permanente study finds shingles vaccine remains effective after chemotherapy
2014-08-05
PASADENA, Calif., August 5, 2014 — The herpes zoster vaccine continues to be effective in protecting older adults against shingles, even after they undergo chemotherapy, according to a Kaiser Permanente study published today in the journal Clinical Infectious Diseases.
Researchers examined the electronic health records of more than 21,000 Kaiser Permanente patients in Southern California who were 60 years of age and older and received chemotherapy between January 2007 and December 2012.
Researchers found that those patients who were previously vaccinated with zoster ...
Electronic cigarettes: many questions, limited research
2014-08-05
August 5, 2014 – Electronic cigarettes (ECIGs) are booming in popularity—but there's still only limited evidence on their potential health risks, or their advertised benefits in helping people to quit smoking, according to a research review in the July/August Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
Based on their review, Alison B. Breland, PhD, of Virginia Commonwealth University, Richmond, and colleagues, write, "[V]ery ...
