Gliders For Mobil Communication
The Moscow scientists have suggested that the tele- and radiobroadcast and vehicular communication transponders should be installed on the gliders instead of the towers. If such gliders can be raised up on the firm kevlar ropes to the height of 10-15 kilometres, then only three transponders will be required to ensure stable communication.... view more... (2002-06-21)
The Malignancy of Cerebral Tumours could be detected by means of Magnetic Resonance
Magnetic resonance is increasingly being used for the detection of cerebral tumours. Nevertheless, while the technique detects the existence of the tumour it does not enable us to tell whether in the case of malignant tumours the tumour cells are actively proliferating or not. A research team at the Universitat Autònoma de Barcelona has... view more... (1999-06-04)
Nicotine rush hinges on sugar in neurons
When nicotine binds to a neuron, how does the cell know to send the signal that announces a smoker's high" view more (2007-07-23)
Scientists make breakthrough in understanding muscle contraction
Professor Susan Wray, who heads the UK's top rated Department of Physiology, and Dr. Ted Burdyga, are studying muscles in the wall of the ureter, which connects the kidney to the bladder, to understand how muscles respond to signals in the body telling them to contract or relax. view more (2005-08-01)
Hyper-SAGE boosts remote MRI sensitivity
A new technique in Magnetic Resonance Imaging dubbed "Hyper-SAGE" has the potential to detect ultra low concentrations of clincal targets, such as lung and other cancers. view more (2009-10-12)
Turn back, wayward axon
To a growing axon, the protein RGMa is a "Wrong Way" sign, alerting it to head in another direction. As Hata et al. demonstrate in the March 9, 2009 issue of the Journal of Cell Biology, translating that signal into cellular action requires teamwork from two receptors. view more (2009-03-09)
UC Riverside researcher develops novel method to grow human embryonic stem cells
The majority of researchers working with human embryonic stem cells (hESCs) - cells which produce any type of specialized adult cells in the human body - use animal-based materials for culturing the cells. But because these materials are animal-based, they could transmit viruses and other pathogens to the hESCs, making the cells unsuitable for... view more... (2008-08-20)
Noise-Immune Stethoscope Helps Medics Hear Vital Signs in Loud Environments
A new type of stethoscope enables doctors to hear the sounds of the body in extremely loud situations, such as during the transportation of wounded soldiers in Blackhawk helicopters. view more (2006-11-29)
How to make microwaves on a chip to replace X-rays for medical imaging and security
Is microwave radiation the nondestructive imaging technology of the future? Microwaves with frequencies from a few hundred gigahertz (GHz) up to slightly over 1 terahertz (THz), penetrate just a short distance into surfaces without the ionizing damage caused by X-rays. view more (2008-05-30)
VERITAS telescopes help solve 100-year-old mystery: The origin of cosmic rays
Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light. view more (2009-11-03)
Dangerous technology -- Mobiles should be kept away from hospital beds
Mobile phones should come no closer than one meter to hospital beds and equipment, according Dutch research published in the online open access journal, Critical Care. view more (2007-09-06)
Radiation Dose Drastically Reduced During Whole Chest MDCT
Emergency physicians who evaluate patients with non-specific chest pain using whole chest multi-detector CT (MDCT) combined with retrospective electrocardiogram (ECG) gating can reduce the patient radiation dose by 71% using MDCT combined with prospective ECG triggering instead. view more (2009-06-24)
NASA's Aqua Satellite sees Tropical Storm Parma lingering in the Luzon Strait
Two instruments on NASA's Aqua satellite captured views of Tropical Storm Parma early today, October 5, while it was almost stationary in the Luzon Strait and it appears that it will sit there for several days. view more (2009-10-06)
Can Eurofighter's radar win UK's biggest engineering prize?
BAE Systems Avionics Group, based in Edinburgh, has been shortlisted for this year's £50,000 Royal Academy of Engineering MacRobert Award, the UK's most coveted prize for engineering innovation, for the world's first airborne radar that can see all the targets all the time. The unique ECR-90 microwave radar was developed specially for... view more... (2000-07-03)
Chronic stress alters our genetic immune response
Most people would agree that stress increases your risk for illness and this is particularly true for severe long-term stresses, such as caring for a family member with a chronic medical illness. view more (2008-08-27)
Nose-on-a-chip Aims To Mimic The Real Thing
An ambitious project is underway to build the world's smallest electronic nose. If the project succeeds, it is expected that the technology would have many potential applications in areas such as environmental monitoring, healthcare and food safety. The aim is to combine the odour sensors together with the signal processing components on to a... view more... (2002-03-04)
Hydrogen Peroxide's Link to Living Cells
If a circadian rhythm is like an orchestra - the united expression of the rhythms of millions of cells - a common chemical may serve as the conductor, or at least as the baton. view more (2009-11-04)
Twanging rat whiskers yields insight into sensing machinery
High-speed video of rats using their whiskers to explore different surfaces has given researchers significant insights into the subtle mechanics of their tactile sensory system. view more (2008-02-28)

A step closer to safer aviation in Africa
ESA PR 12-2003. Between 24 and 26 February, a number of trial flights into Dakar using the EGNOS (European Global Navigation Overlay Service) Test Bed system were carried out to show how the planned provision of Global Navigation Satellite System (GNSS) services over Central Africa could be implemented. ASECNA (Agence pour la... view more... (2003-02-27)
