A new cancer vaccine platform works by enhancing the ability of the immune system to recognize cancer by leveraging anti-viral memories it already has - due to the COVID-19 pandemic, the worst outbreak of the last 70 years.
Energy lost from hot engines could save billions of dollars if it could be captured and converted into electricity via thermoelectric devices, according to Clemson University physicist Terry Tritt.
“Thermoelectric generators are currently used in NASA’s deep-space probes to convert the heat of radioactive elements to electrical energy, powering these systems for over 30 years,” Tritt said. “Thermoelectric energy conversion is a solid-state technology that is environmentally friendly. One of the more promising ‘down-to-earth’ applications lies in waste-heat recovery in cars.”
Otto, the first of the two ALMA antenna transporters, was given its name at a ceremony on the compounds of heavy-vehicle specialist Scheuerle Fahrzeugfabrik GmbH, in Baden-Württemberg. This new colossus is 10 meters wide, 20 meters long and 6 meters high and will be shipped to Chile by the end of the month.
The transporter was named 'Otto' in honor of Otto Rettenmaier, the owner of the Scheuerle company. "The rather unusual move to name a vehicle is a recognition of the remarkable achievement these unique machines represent," said Hans Rykaczewski, the European ALMA Project Manager. "Their sizes alone would justify using superlatives to describe them.
Correlation is not causation but a new study in the journal Fertility & Sterility found that mothers who experienced an increase in weight from the beginning of the first pregnancy to the beginning of the second pregnancy may be slightly more likely to give birth to a baby boy during their second pregnancy.
A slightly greater number of males than females are born worldwide every year but in recent decades there has been a decline in the ratio of male to female newborns in several industrialized countries, including Canada, Denmark, England, Germany, Japan and the United States.
That may be the result of nutrition, say researchers from Harvard School of Public Health (HSPH) and Karolinska Institutet in Stockholm, Sweden.
A remarkable change takes place in the brains of tiny songbirds every year, and some day the mechanism controlling that change may help researchers develop treatments for age-related degenerative diseases of the brain such as Parkinson’s and dementia.
Researchers from the University of Washington and the University of California, Berkeley, report a striking shrinkage in the size of the brain regions that control singing behavior of Gambel’s white-crowned sparrows. This transformation is triggered by the withdrawal of testosterone, a naturally occurring steroid hormone, and is apparent within 12 hours. The study is the first to report such rapid regression of brain nuclei caused by the withdrawal of a hormone and a change in daylight conditions in adult animals.
Ford Motor Company announced that soy-based polyurethane foam will be used in seats in the 2008 Ford Mustang. Ford spent seven years researching biomaterials with various industry representatives. Partnerships with Urethane Soy Systems Company (USSC) and Lear Corporation made flexible foam technology a reality in Ford vehicles.
"Consumers may not realize that petroleum is a major ingredient in auto applications such as seating," says Todd Allen, United Soybean Board (USB) New Uses chair and a soybean farmer from West Memphis, Ark. "The move by Ford to replace petroleum in auto interiors with soybean oil is revolutionary, for the automotive industry."
Over the years, two strands of thought on sustainable development have emerged; ecologism and environmentalism. Ecologism offers a solution by emphasizing the need for major socioeconomic reform aimed at a post-industrial era. Environmentalism focuses on the preservation, restoration, and improvement of the natural environment within the present framework.
Writing in International Journal of the Environment and Sustainable Development, Rasmus Karlsson suggests that space could provide us with a third alternative; a sustainable future not possible from an earthbound only perspective. An industrial space age.
Every year, in Germany alone, around 7000 people wait for a new cornea to save their eyesight. But donor corneas are in short supply. In an EU project, researchers have developed an artificial cornea which is to be clinically tested in early 2008.
A patient whose cornea is damaged through a congenital malformation, hereditary disease or corrosion is at risk of going blind. One solution is to implant a donor cornea. The central part of the natural cornea is removed in a circular fashion, and the new cornea is inserted and sutured in place. A vast number of patients are affected: every year, 40,000 people in Europe alone hope for a donor – often in vain.
Physiotherapy ultrasound machines are commonplace in medicine and sports injury treatment but if patients are treated with the incorrect level of ultrasonic power it could not only be less helpful, it could lead to further injury.
Calibration is the answer and scientists at the National Physical Laboratory (NPL) say they have created technology that can greatly improve the accuracy of the calibration and therefore the quality of the treatment.
NPL has developed an acoustic absorber that can be retro-fitted into current calibration equipment to increase its accuracy.
Duke University Medical Center researchers believe they have discovered why the appendix exists and what purpose it serves in modern humans.
They think it is used to 'reboot' the digestive system and produce the bacteria sometimes eliminated by disease. How is it that people have them removed and live normal lives afterward?
In modern times, it is relatively unimportant. In crowded areas people can easily replace lost bacteria from contact with others but in ancient times, when isolation was more common or when diseases such as cholera or amoebic dysentery struck and eliminated the stomach's good bacteria, the appendix was likely how the human body regenerated good bacteria.
Computer and behavioral scientists at the University at Buffalo say they are working on a system to compute a numerical score that determines the likelihood that someone is about to commit a terrorist act. Their technology will track faces, voices and other biometrics against scientifically tested behavioral indicators to provide that numerical score for an individual.
“The goal is to identify the perpetrator in a security setting before he or she has the chance to carry out the attack,” said Venu Govindaraju, Ph.D., professor of computer science and engineering at the University at Buffalo School of Engineering and Applied Sciences. Govindaraju is co-principal investigator on the project with Mark G.
Why don't we know more about Lake Ellsworth? Because it's a frozen lake. Buried under two miles of ice. In Antarctica.
But Northumbria glaciologist Dr John Woodward, together with experts from the British Antarctic Survey and Edinburgh University, will spend five months working in sub zero conditions to unlock some of its secrets and discover what life may exist there.
More than 150 subglacial lakes have been identified in Antarctica, cut off from the outside world by thick caps of ice for tens or even hundreds of thousands of years. Any life forms will have had to adapt to complete darkness, very few nutrients, crushing water pressures and isolation from the atmosphere.

Most people who have tried to install new computer software are happy to know that a common set of default options is available. For many, they will work fine and customization is only required in a few instances, which leads to less technical support, frustration and downtime.
Can that same computer software model work in health care?
In an opinion article in the September 28 issue of the New England Journal of Medicine, lead author Scott D. Halpern, M.D., a fellow in the division of Pulmonary, Allergy and Critical Care Medicine in the University of Pennsylvania Health System, and colleagues, argue that these concepts applied by marketers should also be used by the medical community to benefit patients.
