New study suggests cause of debilitating skin condition
A new technique that will enable doctors to see` things happening at the molecular level using standard imaging techniques has been developed by Oxford scientists. The technique has initially been directed towards multiple sclerosis, but long-term it has the potential to be used for a vast range of health problems. The findings are published by Nature Medicine on Monday 24 September.
Sizing cells up: Researchers pinpoint when a cell is ready to reproduce
New findings from researchers at Wake Forest University Baptist Medical Center and colleagues suggest why some people with kidney failure can develop a rare tightening and swelling of the skin and other organs, including the lungs and heart.
Victimization for sexual orientation increases suicidal behavior in college students
For more than 100 years, scientists have tried to figure out the cell size problem: How does a cell know when it is big enough to divide? In research conducted in budding yeast (Saccharomyces cerevisiae), scientists at Rockefeller University have now identified the cellular event that marks the moment when a cell knows it is big enough to commit to cell division and spawn genetic replicas of...
Rare albino ratfish has eerie, silvery sheen
The film and television series M*A*S*H* featured the song Suicide is Painless, but new research refutes that idea and indicates that being victimized because of sexual orientation is a chief risk factor for suicidal behavior among gay, lesbian and bisexual college students.
Cancer cells in blood can identify risk of recurrence in breast cancer
A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound.
Discovery of widespread tumor growth gene holds promise for effective anti-cancer treatment
Cancer cells circulating in the blood, or circulating tumour cells (CTCs), are known to be associated with a bad prognosis in women with metastatic breast cancer. Now, for the first time, a group of scientists have shown that they can also detect CTCs before and after chemotherapy treatment and hence may be able to identify those patients likely to have a recurrence of their cancer after such...
Droplets that Roll Uphill
Italian scientists will announce today (Monday September 24) that they have found a new and promising target for anti-tumour therapy in cancer. Professor Saverio Alberti, from the CESI, University of Chieti Foundation, Chieti, will tell the European Cancer Conference (ECCO 14) that he and his team have found a widespread mechanism for the stimulation of tumour growth in man, and that this is...
FDA recalls Axcil and Desirin
A recent experiment conducted by physicists at University of Bristol in the United Kingdom has shown that liquid drops can defy gravity. Droplets of liquid on an inclined plate that is shaken up and down can travel uphill rather than sliding down. In fact, if the plate vibrates at the right rate, the droplets will always travel counter-intuitively up the incline.
Homeland Security Cyber Attacks Probed
The U.S. Food and Drug Administration announced the recall of two sexual enhancement products -- Axcil and Desirin -- because of undeclared, ingredients.
If you want more babies, find a man with a deep voice
(AP) -- A top homeland security lawmaker has called for an investigation into possible cyber attacks on computer systems at the Homeland Security Department.
In sex life of jumping spiders, size matters
Men who have lower-pitched voices have more children than do men with high-pitched voices, researchers have found. And their study suggests that for reproductive-minded women, mate selection favours men with low-pitched voices.
Magnetic Snakes Create Water Current
From post-coital cannibalism to love at first sight, the sex life of the African jumping spider is full of surprises, according to a new study.
NASA postpones Dawn spacecraft launch
Physicists at Argonne National Laboratory have found that magnetic particles suspended in water and subjected to an alternating magnetic field will form snake-shaped structures that can control the flow of the surrounding fluid.
NASA Restarts Telescope Mission to Detect Black Holes
The launch of NASA's Dawn spacecraft was postponed Monday because of weekend fueling delays.
New study questions the validity of publishing hospital mortality rates
NASA has made a decision to restart an astronomy mission that will have greater capability than any existing instrument for detecting black holes in the local universe.
Novel strategy under study for aggressive leukemia
A previous study of mortality rates for congenital heart surgery used routinely available hospital data that were misleading, according to a report published today on bmj.com which questions the validity of such data being made public.
Pomegranate Could Fight Cancer
A novel strategy to hopefully beat into oblivion one of the most aggressive forms of acute myelogenous leukemia combines the strengths of some of the newest leukemia agents, researchers say.
Scientists get first look at nanotubes inside living animals
Researchers in California are reporting new evidence explaining pomegranate juice`s mysterious beneficial effects in fighting prostate cancer. In a study scheduled for the Sept. 19 issue of ACS` Journal of Agricultural and Food Chemistry, a bi-weekly publication, Navindra Seeram and colleagues have found that the tart, trendy beverage also uses a search-and-destroy strategy to target prostate...
Scientists model a cornucopia of Earth-sized planets
Rice University scientists have captured the first optical images of carbon nanotubes inside a living organism. Using fruit flies, the researchers confirmed that a technique developed at Rice -- near-infrared fluorescent imaging -- was capable of detecting DNA-sized nanotubes inside living fruit flies.
Solving a Dragonfly Flight Mystery
In the Star Wars movies fictional planets are covered with forests, oceans, deserts, and volcanoes. But new models from a team of MIT, NASA, and Carnegie scientists begin to describe an even wider range of Earth-size planets that astronomers might actually be able to find in the near future.
Weight gain between first and second pregnancies associated with increased odds of male second child
Dragonflies adjust their wing motion while hovering to conserve energy, according to a Cornell University study of the insect's flight mechanics. The revelation contradicts previous speculation that the change in wing motion served to enhance vertical lift.
NASA aims to put man on Mars by 2037
A slightly greater number of males than females are born worldwide every year. In recent decades, although there are still more baby boys born than girls, there has been an apparent decline in the ratio of male to female newborns in several industrialized countries, including Canada, Denmark, England, Germany, Japan and the United States. That has led researchers to ask: Are there any factors that...
Gaming world braces for industry 'killer' Halo 3
NASA aims to put a man on Mars by 2037, the administrator of the US space agency indicated here Monday.
Printing with enzymes instead of ink
The gaming world braced Monday for the highly anticipated release of "Halo 3," expected to be a blockbuster for Microsoft and its struggling XBox 360 game console.
With all the advances in printing technology in recent years, the latest may rise to the top of a list that would make Gutenberg gasp. Scientists in North Carolina are reporting development and testing of a method for printing finely-detailed microscopic images with an enzyme, rather than ink. The report is scheduled for the Sept. 24 issue of ACS` Journal of Organic Chemistry.
