Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term "cell signaling" was coined more than 30 years ago to describe this process. Now, for the first time, scientists have quantified the data capacity of a biochemical signaling pathway and found a surprise – it's way lower than even an old-fashioned, dial-up modem. "This key biochemical pathway is involved in complex functions but can transmit less than one bit – the smallest unit of information in ...

GALVESTON — Researchers have found that a protein linked to cell division and migration and tied to increased cell proliferation in ovarian tumors is also present at high levels in breast cancer specimens and cell lines. The protein, dubbed "UNC-45A," was also determined to be more active in breast cancer cells than in normal breast cells. University of Texas Medical Branch at Galveston scientists describe these findings and others in a paper now online in the Journal of Molecular Biology. "As a result of earlier work, we hypothesized that UNC-45A should be critical ...

If all goes well, the LAMP (Loop-mediated Isothermal Amplification) test - which has completed design and development phases - will ...

Part 1: Twitter If you think Twitter is just for teenagers and celebrities, think again. Sometimes we are asked to help people with their social media; many think that, for business, LinkedIn may be relevant but Twitter and Facebook are not going to attract clients and therefore not worthy of their attention. They couldn't be more wrong. Before going any further, I would like to share a couple of experiences that I recently had connecting with businesses on Twitter. Having endured hours of frustration being kept on hold on their help line, all to no avail, I tweeted ...

COLLEGE STATION, Sept. 15, 2011 – In the next 20 years, more than 590,000 square miles of land globally — more than twice the size of Texas — will be gobbled up by cities, a trend that shows no signs of stopping and one that could pose threats on several levels, says a Texas A&M University geographer who is part of a national team studying the problem. Burak Güneralp, a research assistant professor in the Department of Geography at Texas A&M, says urban areas are growing faster than urban populations and by 2030, urbanized land worldwide will grow by 590,000 square miles ...

CHICAGO – Ovarian cancer is a rare but often deadly disease that can strike at any time in a woman's life. It affects one in 70 women and in the past was referred to as a silent killer, but researchers have found there are symptoms associated with ovarian cancer that can assist in early detection. Experts at Northwestern Memorial say the best defense is to make use of preventive methods, understand the risks and recognize potential warning signs of ovarian cancer. "Currently, there is no reliable screening test to identify early ovarian cancer. Women need to focus on ...

Berkeley, CA — The installed cost of solar photovoltaic (PV) power systems in the United States fell substantially in 2010 and into the first half of 2011, according to the latest edition of an annual PV cost tracking report released by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab). The average installed cost of residential and commercial PV systems completed in 2010 fell by roughly 17 percent from the year before, and by an additional 11 percent within the first six months of 2011. These recent installed cost reductions are attributable, ...

Watching children on the playground, we see them run, climb, slide, get up, and do it all again. While their movements are continuous, we language-users can easily divide them up and name each one. But what about people—babies—who don't yet have words? How do they make sense of a world in motion? An upcoming study in Psychological Science, a journal published by the Association for Psychological Science, finds that infants at seven to nine months are able to slice up the flow of events, even before they start to speak. And the researchers believe they've identified the ...

Researchers have identified promising new therapies for ependymoma, a rare tumor with few treatment options. St. Jude Children's Research Hospital investigators led the effort, which used a new, faster drug development system that combines the latest drug screening technology with the first accurate animal model of the tumor. Investigators identified several dozen new and existing drugs as possible ependymoma treatment candidates. The drugs were found by screening 5,303 existing medicines, natural products and other compounds for activity against the tumor, which develops ...

Both new publications are part of GSA's From Publication to Practice series, which aims ...

PHILADELPHIA - The changing tide of Alzheimer's diagnosis presents new challenges to the public, physicians and lawmakers: if you could find out your Alzheimer's risk, would you want to know? How should doctors tell you your risk? And what does it mean for the many newly diagnosed Americans still in the workplace? Despite the emergence of new tools that can diagnose Alzheimer's earlier, no effective interventions have been identified to stop the progression of the disease. A new report from the Perelman School of Medicine at the University of Pennsylvania tackles the ...

NASA's TRMM satellite peers through clouds and can decipher the rate rain is falling within a tropical cyclone, and data from the satellite shows that the heaviest rainfall is occurring in the northwestern quadrant of the storm, away from Bermuda. The Tropical Rainfall Measuring Mission (TRMM) satellite traveled above tropical storm Maria on Thursday, September 15, 2011 at 1001 UTC ( 6:01 a.m. EDT). TRMM has the ability to measure rainfall rates and cloud heights, two factors that are important and helpful to the National Hurricane Center (NHC) meteorologists who are ...

A new model of obsessive-compulsive disorder (OCD) that mirrors both symptoms of the disease and the timing of its treatment in humans has been created by University of Chicago researchers, according to a new study. Using the model, researchers isolated a single neurotransmitter receptor in a specific brain region responsible for their model's OCD-like symptoms, offering new insight into the cause of the disorder. Further research with the model may point the way to new treatments for both OCD and autism, said Nancy Shanahan, PhD, lead author of the paper in Biological ...

Tropical Storm Roke is showing some signs of intensification on NASA infrared satellite imagery, as areas of strong convection and very cold cloud tops were spotted. Kadena Air Base in Okinawa is now in Roke's sights and should be making preparations. NASA's Aqua satellite flew over Roke yesterday and the Atmospheric Infrared Sounder (AIRS) instrument showed powerful convection building around the storm's center and over the northern edge. Meanwhile, dry air is wrapping into the low-level center from the southwest, and limiting cloud development. Infrared imagery provides ...

Infrared satellite imagery from NASA's Aqua satellite yesterday showed powerful convection building in the low pressure area known as System 94W and provided forecasters with an inside look that the low was strengthening. System 94W did intensify and became Tropical Storm Sonca today. Infrared imagery is gathered by the Atmospheric Infrared Sounder (AIRS) instrument that flies on NASA's Aqua satellite. It provides valuable information to forecast organizations such as the Joint Typhoon Warning Center and National Hurricane Center about cloud temperatures and heights and ...

AMES, Iowa – Even though a dwarf galaxy clear across the Milky Way looks to be a mouse, it may have once been a bear that slashed through the Milky Way and created the galaxy's spiral arms, writes an Iowa State University astronomer in the journal Nature. Curtis Struck, an Iowa State professor of physics and astronomy, uses a News & Views commentary in the Sept. 15 issue of Nature to add context and color to a study published in the same issue by a research team led by Chris W. Purcell of the University of Pittsburgh. The Purcell group reports that the Sagittarius Dwarf ...

From the very beginning our philosophers and scientists realized that the key to great societies was wisdom. They saw that wisdom was real and that if only they could figure out what it is and how to teach it; they would be able to create wise societies. Ever since the times of Aristotle till today, man has been trying to figure out wisdom by putting wisdom under the microscope. As wisdom is an innate property of the pure self it is a secondary entity; just like fragrance is a property of the flower. It is exactly like a symptom of a disease. So by putting wisdom under ...

PHILADELPHIA--It is a commonly held that information on Wikipedia should not be trusted, since it is written and edited by non-experts without professional oversight. But researchers from the Kimmel Cancer Center at Jefferson have found differently, according to a study published online Sept. 15 in the Journal of Oncology Practice. Reassuringly, they found that cancer information found on a wiki was actually similar in accuracy and depth to the information on a peer-reviewed, patient-oriented cancer web site. There is one caveat, however: they found that the information ...

Cincinnati, OH, September 16, 2011 -- Pharmaceutical poisoning remains a common childhood injury, despite years of concerted prevention efforts, such as improved safe guards on packaging.
