Scientists from Leicester have discovered a radical new approach to making artificial platelets to help stop bleeding in patients who have too few platelets of their own. This invention could be a major breakthrough for cancer patients suffering from severe or life threatening bleeding.
The development of this highly innovative product has been made possible thanks to a major funding round of £3.1m led by Quester, including investment from NESTA (the National Endowment for Science, Techn
Temex of France, a specialist in the field of high-performance time and frequency components and sub-systems, has launched a small-size Oven Controlled Crystal Oscillator (OCXO) in a 25mm x 25mm flat-pack package for space applications. This new low-consumption OCXO is designed specifically for applications such as deep-space up/down link transceivers where a wide operating temperature range and low energy consumption are critical.“

Sensors which are able to predict when mechanical parts in machinery and transport will breakdown before they actually do could be introduced by 2010, slashing maintenance costs across the manufacturing, automotive and plant machinery industries.
Scientists at The University of Manchester are to develop a new type of wireless sensor which will be able to remotely monitor mechanical parts and systems. The aim is to produce a sensor which can be seamlessly fitted inside gearboxes,
A high-capability new infrared satellite, ASTRO-F, was successfully launched last night by the Japan Aerospace Exploration Agency (JAXA). In a collaborative effort involving ESA and scientists across Europe, the spacecraft is now being prepared to start its mapping of the cosmos.
Orbiting the Earth, ASTRO-F (to be renamed Akari (light) now that it is in orbit) will make an unprecedented study of the sky in infrared light, to reveal the distant phenomena hidden from our eyes that tell th
Scientists who hope to use quantum dots as the building blocks for the next generation of computers have found a way to make these artificial atoms communicate.
“Essentially, the dots talk to each other,” said Ameenah Al-Ahmadi, an Ohio University doctoral student who published the findings with Professor of Physics Sergio Ulloa in a recent issue of the journal Applied Physics Letters.
The dots are tiny, engineered spherical crystals about 5 nanometers in diameter. An
Independent research teams from Harvard Medical School and Children’s Hospital Boston have identified a master protein that sheds light on one of neurobiology’s biggest mysteries–how neurons change as a result of individual experiences. The research, which appears in two papers in the latest issue of Science (Feb 17), identifies a central protein that regulates the growth and pruning of neurons throughout life in response to environmental stimuli. This protein, and the molecular pathway it guid
In an important study forthcoming in the March 2006 issue of the American Naturalist, biologists from Yale University, University of Florida, and Dartmouth University explore the dynamics of pathogen survival and shed new light on a longstanding mystery: why some infectious diseases are limited to small outbreaks and others become full-blown epidemics.
“The capacity of a virus to propagate upon a novel host apparently is conditional on the recent experience of preceding generat
Vical Incorporated (Nasdaq:VICL) announced today that an Ebola vaccine candidate administered using Vical’s proprietary DNA delivery technology was safe and well tolerated, and produced both antibody and T-cell Ebola-specific responses in all healthy volunteers who received the full 3 doses of vaccine.
The Phase 1, randomized, placebo-controlled, dose-escalation study, the first human trial for any Ebola vaccine, was sponsored by the National Institute of Allergy and Infectious Di
Each year, the red knot, a medium-sized shorebird, makes a 20,000-mile round-trip from the southern tip of Argentina to the Artic Circle – one of the longest migrations of any bird. And each year from April to June, the red knot stops over in the Delaware Bay to feed on horseshoe crab eggs resulting from the largest spawning of horseshoe crabs found on the East Coast of the United States.

Bill Hopkins, fisheries and wildlife associate professor in Virginia Tech’s College of Natural Resources, and colleagues doing research at the Savannah River Ecology Laboratory and in the field, have demonstrated that amphibians are exposed to contaminants through maternal transfer, as has been proven for other vertebrates.
The research has been published in the National Institutes of Health (NIH) journal, Environmental Health Perspectives (“Reproduction, Embryonic Develop
Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences. Potential applications for the new sensors range from rapid detection of hazardous biological agents to simpler and more efficient forensic identification.
In the Jan. 27 issue of the journal Science, chemical and biomolecular engineering professor Michael
The differences in the male and female immune responses, which make females more prone to autoimmune disease and males more subject to infections, are established during puberty. In a study published today in the open access journal BMC Immunology, researchers identified one of the mechanisms responsible for the difference in immune response between male and female mice. They show that this sexual disparity is established during puberty and is influenced by sex hormones. These findings have implica
Heart health risk factors and lifestyle choices, such as exercise, learning new things and staying socially connected, are associated with maintaining brain health as we age according to a new report from a multi-Institute collaboration of the National Institutes of Health (NIH) published online today in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.
“Many of the factors that can put our brain health at risk are things we can modify and control,” said Wi
To provide essential data for the rebuilding of the ravaged levees in New Orleans, engineers from Rensselaer Polytechnic Institute will be studying small-scale models of sections of the flood-protection system. The researchers will replicate conditions during Hurricane Katrina by subjecting the models to flood loads, supplying important information to help the U.S. Army Corps of Engineers prepare the city for next hurricane season and beyond.
The researchers will build and test models of t
If women want the best possible service at a clothing store, they had better be looking fashionable and well-groomed before they hit the mall.
A new study found that well-dressed and groomed women received the friendliest and, in some cases, fastest service from salesclerks.
Researchers secretly observed interactions between customers and salesclerks at three large-sized women’s clothing stores, timing how long clerks took to greet customers, and rating the clerks&
Atlantic expeditions uncover secret sex life of deep-sea nomads
For centuries scientists have thought of deep-sea pelagic fish as nomadic wanderers, in part because information about them was so limited. However, new results from the ongoing Mid-Atlantic Ridge Ecosystems program (MAR-ECO), a Sloan Foundation-sponsored component of the Census of Marine Life, have revealed that these fishes may in fact be gathering at features such as ridges or seamounts to spawn. The research has im
