If someone with diabetes is driving down the road and starts to feel a hypoglycemic attack coming on, that person may realize what's happening and stop to get a bite to eat. Or not, which could lead to trouble. That latter scenario inspired Medtronic's "M-Powered Concept Car" and its onboard glucose-monitoring system.

With data transmitted via Bluetooth, the wireless setup lets people wearing a continuous glucose-monitoring system (CGMS) get readings of their blood sugar levels through audio and visual cues from the car's dashboard. Medtronic, a medical-device manufacturing company, premiered the car at the 68th Annual Scientific Sessions of the American Diabetes Association, … Read more

If you want to know staphylococcal enterotoxin from streptococcal exotoxin, consider adding the Borden Institute's latest edition of Medical Aspects of Biological Warfare to your nightstand.

This scholarly tome is an authoritative update on the weaponization of biological agents. A distinguished group of authors take us from familiar standbys (anthrax, plague, smallpox) through the potential horrors of inadvertent or deliberate release of "oranimal"--bioengineed plant organisms--and onto the "arbitrary use of human embryonic tissue in research."

An update from the 1997 edition was required because of the increased threat posed by biological warfare and terrorism, … Read more

About a decade ago, wireless heart monitors hooked to patients at Baylor University Medical Center in Dallas went on the fritz, causing much scrambling among the building's engineering team.

The culprit, as it turned out, was interference from a nearby broadcast television station, which was testing its digital signal on the same channel where some of the medical devices operated, as detailed in the journal Biomedical Instrumentation & Technology a few years ago. The Federal Communications Commission ultimately cordoned off spectrum just for that purpose, although migrating there was largely voluntary.

Now, hospital administrators and medical device manufacturers fear … Read more

This replica of the Star Trek "Medical Tricorder" makes it clear why they rarely showed a close-up of Bones' device on the original series: It looks like something cobbled together in the garage of that neighbor who's still trying to get his old CB radio to work.

It's interesting to note how a supposed 23rd century device created in 1966 could look like something made in 1967. (Is that foresight-hindsight?) Anyway, if you want one of these collectable novelties, GeekAlerts says it can be had for just $40 in October, complete with removable scanner. That's … Read more

What happens in Vegas could be contagious; but don't worry, despite the recent ricin scare on the Strip, your chances of dying from exotic poison or a bio-engineered infection are pretty slim - even at the buffet.

Still, companies are betting their R&D budgets that the government will ante up to protect you from the toxin de jour. Their odds are good. Universal Detection Technology received a rush of orders for its ricin detection kit after a man was found in critical condition in a Las Vegas motel room with a case of suspected ricin poisoning.

DUBLIN, Ireland--It knows when you are sleeping. It knows when you're awake.

"It" is neither Santa Claus nor a monster in the closet. Rather, it's technology from Dublin-based BiancaMed that can track and analyze a person's sleep and night-breathing patterns without disturbing the sleeper, said CTO Philip de Chazal. In contrast with some sleep analysis systems used in laboratories, the person doesn't need to wear electrodes or lie on a plastic pad. Instead, a wireless device tracks the sleeper's movements.

Software devised by BiancaMed separates the signals corresponding to breathing and other body … Read more

A team of respected security researchers known for their work hacking RFID radio chips have turned their attention to pacemakers and implantable cardiac defibrillators.

The researchers will present their paper, "Pacemakers and Implantable Cardiac Defibrillators: Software Radio Attacks and Zero-Power Defenses," during the "Attacks" session of the 2008 IEEE Symposium on Security and Privacy, one of the most prestigious conferences for the computer security field.

The authors of the paper are listed as: Shane S. Clark, Benessa Defend, Daniel Halperin, Thomas S. Heydt-Benjamin, Will Morgan, Benjamin Ransford, Kevin Fu, Tadayoshi Kohno, William H. Maisel.

Kevin Fu, an assistant professor at the University of Massachusetts Amherst, … Read more

CORK, Ireland--A radiation detector initially created to protect orbiting satellites has found a new purpose inside cancer patients.

The Tyndall National Institute--a scientific research institute and graduate school in Cork, Ireland--has come up with a radiation detector that fits inside an implantable medical device that measures how well radiation therapy is working. The FDA approved the use of the DVS (Dose Verification System) from North Carolina's Sicel Technologies last August for breast cancer and prostate cancer patients, said Brendan O'Neill, head of the central fabrication facility at Tyndall.

The DVS collects information about patients and then transmits … Read more

Science teachers everywhere have had always had to face the question, "Dr. T., when are we going to use this?" In pop culture, it has always seemed to me that the general public is science-phobic, unless they are shopping for beauty products. Then it's "bring on the polypeptides," no matter how dubious the product's claims are.

But a new discovery has promise to deliver a genuine benefit, and brings nanotechnology into real life. Last week's edition of NPR's Science Friday explained that geckos use nanotubes to stick to glass surfaces. Now researchers … Read more
