Bioelectronic ‘signatures?hold key to DNA mutations

... for diabetes, the FDA approved Gluco Watch, which monitors glucose levels through human sweat. “The ultimate goal is to make something similar to a hand-held glucose monitor for future genetic testing,?Wang says. “The electronic detection of DNA is a thing of beauty. You can make it small, low-power, inexpe...

Industrial contaminants spread by seabirds in High Arctic, new Canadian study shows

...allow ponds that ringed the base of the cliffs, as monitors of past contaminant inputs. Noting that Canada has the longest coastline in the world, and seabirds are typically the dominant wildlife found in these coastal ecosystems, Dr. Blais says: "Most of Canada's coastline is at our northern fringe, and nor...

Cyberkinetics, Case to develop system to help restore extremity function

The ultimate goal of the BrainGate System development program is to create a safe, effective and u...

Software might revolutionize glucose monitoring in critically ill patients

...emented GRIP in a 12-bed ICU, forfour months. GRIP monitors glucose levels and recommends theappropriate insulin pump rate and the time at which the next bloodsample should be taken, and indicates situations in which a physicianneeds to be notified. In many ICUs, nurses currently monitor glucose levels manual...

How does the brain know what the right hand is doing?

...s: (1) the outflow hypothesis says that the brain monitors signals it sends to the muscles telling them how strongly to contract, and uses this to predict where the limb has moved to; (2) the inflow hypothesis suggests that the brain relies on information from sensors within tissues that say how far a limb h...

Study by Einstein researchers could lead to a novel strategy for treating obesity

...tti and his colleagues showed how the hypothalamus monitors and regulates glucose levels in the body. The present study shows that this brain region also monitors fatty acid levels and responds by controlling appetite. The study focused on malonyl CoA, a molecul...

Liquid crystals show promise in controlling embryonic stem cells

...erials used to display information on cell phones, monitors and other electronic equipment, can also be used to report in real time on the differentiation of embryonic stem cells. Differentiation is the process by which embryonic stem cells gradually turn into function-specific types of adult cells or so-ca...

New crop of technology reveals plant health

..., transmitters and specialist software, the system monitors the state of the crop on a plant-by-plant basis, in near real-time. PLANTS adhered to a broader vision where the virtual (computing) space was seamlessly integrated with the physical environment. One of its main objectives was to develop the necess...

Five new technologies that promise to transform medicine

...ication will benefit from a miniature implant that monitors and transmits data on heart and breathing rates, blood pressure, and blood sugar levels. And further into the future are links smart pumps that, when signalled, instantly deliver the correct medication. Another prediction is the use of miniature t...

Detecting microalgae in coastal waters

... and time. In vogue are fluorescence-based optical monitors that 'see' chlorophyll a, a plant pigment that is present in all algal species. However, these tools are less effective in turbid coastal waters and do not identify alternative pigments, so cannot distinguish between different types of algal species....

Lab-on-a-chip could speed up treatment of drug-resistant pneumonia

... color-code cells from known strains. A microscope monitors the viable cells -- those that are still reproducing -- and the rate at which they duplicate helps to identify their species. In the next step, different antibiotics are pumped into the chambers. If the cells in a chamber stop reproducing, that in...

A revolution in the monitoring of unborn babies

...ists from The University of Nottingham. The device monitors the baby’s heart for signs of potential danger. It is small and easy to use so that mother’s-to-be can keep a regular check on their baby’s heart beat without having to go into hospital and be attached to a machine. No other technology allows them to...

Ultrasound upgrade produces images that work like 3-D movies

Catching cancer's spread by watching hemoglobin

... to a higher energy state. The other "probe" laser monitors the hemoglobin after the excitation. Sometimes the pump laser is off and there is no two-photon absorption. By subtracting the signal from the "off" state from the "on" state (when two-photon absorption occurs), the researchers remove unwanted scatte...
