Porous metallic boxes can easily be tracked via MRI
Johns Hopkins researchers have devised a self-assembling cube-shaped perforated container, no larger than a dust speck, that could serve as a delivery system for medications and cell therapy.
The relatively inexpensive microcontainers can be mass-produced through a process that mixes electronic chip-making techniques with basic chemistry. Because of their metallic nature, the cubic container’s location in the bo
New Saint Louis University study validates first questionnaire of its kind
A four-question screening tool can predict which older patients with appetite problems are likely to lose weight, placing them at greater risk of death, according to Saint Louis University research.
The questionnaire is called the SNAQ (pronounced snack), the Simplified Nutritional Appetite Questionnaire, and takes less than two minutes to answer.
“This tool tells us whether a poor appeti
High performance computing is becoming increasingly important for international scientific research. It remains unclear, however, whether the conditions for its use (such as training of personnel, accessibility to computers and data, whether the programs are up-to-date, etc.) meet the requirements of modern scientific research. Another question addressed is how computer resources and collaborative platforms need to develop to allow scientists from disciplines as varied as astrophysics, chemistry, ma
The Chemical Industries Association (CIA) today commended the Trade & Industry Committee’s report on its inquiry into ‘Security of Gas Supply’ and strongly agrees with the Committee’s assessment that the UK does not have a properly functioning forward gas market.
The CIA also shares its concern – acutely – over problems of uncertain supply and the high prices caused by dependence of the liberalised UK market on the largely unreformed European one. As the Committee observes, “It is fa
The research team led by Norberto López de La Calle at the Department of Mechanical Engineering at the University of the Basque Country, have designed a new model for optimising the high-speed, 3- or 5- axis milling of complex parts. One of the objectives in this field has been the development of a methodology for the a priori estimation of errors due to flexion of the milling-machine housing system given that some errors, induced by cutting forces, lead to non-compliance with the tolerances of c
The NAPOLEÓN Integrated Project has been recently launched under the leadership of Professor José María Asua of the University Institute of Polymeric Materials (POLYMAT) at the University of the Basque Country (UPV/EHU).
Over a period of four years, 21 European participants, including large and small business enterprises as well as universities, will work on the development of radically new products through the technological process for the production of controlled nanostructured
The University of Manchester has been awarded £5.98m to develop a new class of light alloy solutions that will transform the way aircraft, trains and automobiles are built.
The grant, which will span a five year period, has been awarded by the Engineering and Physical Sciences Research Council (EPSRC) under the Portfolio Partnership Scheme.
Research into improving the performance of light alloys will be carried out in conjunction with Alcan, Novelis, BAE Systems, Airbus,
Scientists from Obninsk in the Kaluga reg. (Russia) have developed a ceramic with unique properties, with heat conductivity and thermoplasticity several times higher than normal ceramics. This means that items made of it, from coffee mugs to fuel pellets for atomic power stations, will serve longer and more reliably than standard ceramics.
During a competition of innovative developments under the 5th International Innovation and Investment Salon that was held 15-18 February 20
Europe is helping to push forward the boundaries of current radio technology looking at the next generation of radio devices. A whole new Ultra WideBand (UWB) communications industry is emerging and once all phases of a major European research effort into UWB are complete, Europe will be in a stronger position to exploit this new technology.
Ultra wideband usually refers to a radio communications technique based on transmitting very-short-duration pulses, down to nanoseconds (billio
Roche and the Competence Center for Systems Physiology and Metabolic Diseases (CC-SPMD) of SystemsX, the Swiss Initiative in Systems Biology, today announced a three-year research partnership. Scientists from Roche and the CC-SPMD will participate in a joint research project entitled «Systems biology of the beta cell-application to type 2 diabetes progression». The project aims to identify novel pathways for drug development in diabetes as well as new biomarkers of beta cell failure for diagnost
The European Space Agency (ESA) announced today support of a new program that will include development of an instrument for testing deep soil samples on Mars in a European mission called ExoMars. A researcher at the University of California, Santa Barbara will direct the development of the instrument.
“We are very excited about this,” said Luann Becker, research scientist with the Institute of Crustal Studies at UC Santa Barbara. “It’s a once-in-a-lifetime opportunity.” Testing by
Ultraviolet flashes associated with surface crustal fields, not poles
Auroras similar to Earth’s Northern Lights appear to be common on Mars, according to physicists at the University of California, Berkeley, who have analyzed six years’ worth of data from the Mars Global Surveyor.
The discovery of hundreds of auroras over the past six years comes as a surprise, since Mars does not have the global magnetic field that on Earth is the source of the aurora
Physicists propose innovative probe for quantum criticalities
A team of theoretical and experimental physicists from Rice University is preparing a unique probe in hopes of “dialing in” elusive quantum states called “quantum criticalities.” The team is using nanotechnology to create a probe capable of trapping and tuning a single electron to create the rarified physical state in nearby magnetic electrodes.
The probe, a transistor thousands of times smaller than a living
Groups rally to safeguard hundreds of imperiled species
Safeguarding 595 sites around the world would help stave off an imminent global extinction crisis, according to new research published today in the Proceedings of the National Academy of Sciences.
Conducted by scientists working with the 52 member organizations of the Alliance for Zero Extinction (AZE –– www.zeroextinction.org), the study identifies 794 species threatened with imminent extinction, each of which is in
Depression and anxiety are common problems for people whose epilepsy cannot be controlled by medication. A new study found that depression and anxiety improve significantly after epilepsy surgery.
The study, which is published in the December 13, 2005, issue of Neurology, the scientific journal of the American Academy of Neurology, found that the rate of depression and anxiety disorders decreased by more than 50 percent up to two years after the surgery. People who no longer e
Results of self-reported successful aging research released at ACNP Annual Conference
A new study released at the American College of Neuropsychopharmacology’s (ACNP) Annual Meeting suggests that the seniors’ perceptions of the aging process depend not on disease or physical disability, but rather on attitude and coping style. This research, conducted at and funded by the Sam and Rose Stein Institute for Research on Aging at the University of California-San Diego (UCSD) S
