New cancer drug target involving lipid chemical messengers

New cancer drug target involving lipid chemical messengers

PHILADELPHIA — More than half of human cancers have abnormally upregulated chemical signals related to lipid metabolism, yet how these signals are controlled during tumor formation is not fully understood.

Youhai Chen, PhD, MD, and Svetlana Fayngerts, PhD, both researchers in the department of Pathology and Laboratory Medicine at the Perelman School of Medicine, University of Pennsylvania, and colleagues report that TIPE3, a newly described oncogenic protein, promotes cancer by targeting these pathways.

Solar cell efficiency improved

Solar cell efficiency improved

New light has been shed on solar power generation using devices made with polymers, thanks to a collaboration between scientists in the University of Chicago's chemistry department, the Institute for Molecular Engineering, and Argonne National Laboratory.

NASA catches a weaker Edouard, headed toward Azores

NASA catches a weaker Edouard, headed toward Azores

NASA's Aqua satellite passed over the Atlantic Ocean and captured a picture of Tropical Storm Edouard as it continues to weaken. The National Hurricane Center expects Edouard to affect the western Azores over the next two days.

NASA's Aqua satellite flew over Tropical Storm Edouard on Sept. 18 at 1:45 p.m. EDT and the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument took a visible picture that showed the eye had disappeared and the bulk of clouds pushed east of center.

NASA, NOAA satellites show Odile's remnant romp through southern US

NASA, NOAA satellites show Odile's remnant romp through southern US

Former Hurricane Odile may be a bad memory for Baja California, but the remnants have moved over New Mexico and Texas where they are expected to bring rainfall there. NASA's TRMM satellite measured Odile's heavy rainfall rates on Sept. 18, and NOAA's GOES-West satellite saw the clouds associated with the former storm continue to linger over the U.S. Southwest on Sept. 19.

NASA sees Tropical Storm playing polo with western Mexico

Tropical Storm Polo is riding along the coast of western Mexico like horses in the game of his namesake. NASA's Aqua satellite saw Polo about 300 miles south-southeast of Baja California on its track north.

NASA eyes Tropical Storm Fung-Wong move through Northwestern Pacific

Tropical Storm Fung-Wong continued to affect the Philippines while moving north through the Northwestern Pacific Ocean. NASA's Aqua satellite provided infrared data on the storm's clouds that showed some high, strong thunderstorms with the potential for heavy rainfall over the northern and central regions of the country. The storm is now expected to affect three more countries over the next several days.

Dwindling wind may tip predator-prey balance

Dwindling wind may tip predator-prey balance

MADISON, Wis. — Bent and tossed by the wind, a field of soybean plants presents a challenge for an Asian lady beetle on the hunt for aphids. But what if the air — and the soybeans — were still?

Rising temperatures and shifting precipitation patterns may get the lion's share of our climate change attention, but predators may want to give some thought to wind, according to a University of Wisconsin Madison zoologist's study, which is among the first to demonstrate the way "global stilling" may alter predator-prey relationships.

Melanoma risk found to have genetic determinant

(Lebanon, NH 9/18/14)— A leading Dartmouth researcher, working with The Melanoma Genetics Consortium, GenoMEL, an international research consortium, co-authored a paper published today in the Journal of the National Cancer Institute that proves longer telomeres increase the risk of melanoma.

"For the first time, we have established that the genes controlling the length of these telomeres play a part in the risk of developing melanoma," said lead author of the study Mark Iles, PhD, School of Medicine at the University of Leeds (UK).

A better way to track emerging cell therapies using MRIs

Cellular therapeutics – using intact cells to treat and cure disease – is a hugely promising new approach in medicine but it is hindered by the inability of doctors and scientists to effectively track the movements, destination and persistence of these cells in patients without resorting to invasive procedures, like tissue sampling.

Research predicts possible 6,800 new Ebola cases this month

Tempe, Ariz. (Sept. 19, 2014) - New research published today in the online journal PLoS Outbreaks predicts new Ebola cases could reach 6,800 in West Africa by the end of the month if new control measures are not enacted.
