New T-ray Source Could Improve Airport Security, Cancer Detection
Going through airport security can be such a hassle. Shoes, laptops, toothpastes, watches and belts all get taken off, taken out, scanned, examined, handled and repacked. But "T-rays", a completely safe form of electromagnetic radiation, may reshape not only airport screening procedures but also medical imaging practices. Potential new heart attack biomarker uncovered
Researchers have identified cardiac myosin-binding protein C as a potential new diagnostic biomarker for heart attacks, one that may be particularly valuable for mild attacks in which traditional diagnostic proteins may not be abundant enough. Some Outgrow Allergy To Tree Nuts, Johns Hopkins Children's Center Exp
Nine percent of children allergic to almonds, pecans, cashews and other tree nuts outgrow their allergy over time, including those who've had a severe reaction such as anaphylaxis shock, according to researchers at the Johns Hopkins Children's Center. Orbiter Spots Land Bridge on Mars
And the Planetary Society's fascinating blog displays the red planet's natural beauty. Plus: Snazzy Spacesuits for Rich Guys. In Beyond the Beyond. Money Motivates -- Especially When Your Colleague Gets Less
The feelings an individual has on receiving his paycheck depend critically on how much his colleague earns. Hard evidence for this comes from a brain scanner experiment conducted by economists and brain scientists. Low-dose Aspirin Offers Lower Chance Of Asthma
In a large, randomized, placebo-controlled study of 22,071 healthy male physicians, taking a low-dose of aspirin every other day lowered the risk of receiving an initial asthma diagnosis by 22 percent. Zapping The Heart Back Into Rhythm
For 2.3 million Americans whose hearts beat too fast or don't keep a regular rhythm, the answer is usually medicines and occasional electric shocks. But these can cause serious side effects and lose their power over time. That leaves many patients with an irregular heartbeat that saps their strength and raises their risk of having a stroke. Now, a new option offered at the University of Michigan Cardiovascular Center and a handful of other centers nationwide is proving to be a true, lasting cure for the vast majority of people who receive it. Diabetes Drug Shows Promise In Fighting Lethal Cancer Complication
Insulin resistance, the hallmark of type 2 diabetes and a condition often associated with obesity, is paradoxically also an apparent contributor to muscle wasting and severe fat loss that accompanies some cancers, according to new research. Deep Impact Launched And Flying Toward Date With A Comet
NASA's Deep Impact spacecraft began its 431 million kilometer (268 million mile) journey to comet Tempel 1 January 12, 2005 at 1:47:08 p.m. EST. Deep Impact is comprised of two parts, a "fly-by"spacecraft and a smaller "impactor."The impactor will be released into the comet's path for a planned collision on July 4. The crater produced by the impactor is expected to be up to the size of a football stadium and two to 14 stories deep. Ice and dust debris will be ejected from the crater, revealing the material beneath. Researchers Uncover How A Nanoscale 'Compass' Inside Bacteria Orients
"Magnetotactic"microorganisms use a miniature, cellular compass made of a chain of single nanomagnets, called magnetosomes. The entire bacterium is oriented like a compass needle inside the magnetic field. Until now, it was not clear how the cells organise magnetosomes into a stable chain, against their physical tendency to collapse by magnetic attraction.
