Insulin releasing patch draws oral diabetes treatments closer

Of the hundreds of million people around the world that suffer from diabetes, a sizeable portion need to subject themselves to daily insulin injections. But a more palatable way of keeping blood glucose levels in check may be on the way, with scientists developing a patch that attaches to the intestinal wall and releases the hormone after being swallowed in the form of a capsule.

Boozy comet Lovejoy houses building blocks for life

Astronomers have discovered large quantities of alcohol and sugar, as well as the presence of complex organic molocules, on the comet Lovejoy. The observations, made by the 30 meter (98 ft) radio telescope at Pico Veleta, Spain, support the theory that comets may have played an important role in the formation of life on Earth.

Deep-sea bacteria could help neutralize carbon dioxide

Scientists have discovered that a bacterium called Thiomicrospira crunogena can produce carbonic anhydrase, an enzyme that can convert carbon dioxide into bicarbonate. In a new study, scientists from the University of Florida highlight how the bacterium, found in deep-sea regions, could play a role in the race to find solutions to sequester industrial CO2 from the atmosphere.

World View completes major flight test of Voyager spacecraft scale replica

Commercial spaceflight company World View came a step closer to carrying tourists to the edge of space with a successful test flight last weekend. At Page, Arizona, a one-tenth scale replica spacecraft was carried by high-altitude ballon to a height of 100,475 ft (30,624 m) to demonstrate the technology that is intended for use in a full-size version slated to begin commercial flights next year.Read More

Hydrogel infused with snake venom stops bleeding within seconds

Major, uncontrolled blood loss can have major ramifications everywhere from the battlefield to the operating theatre. While blood-clotting medications can be used to stem the flow, often their purpose is thwarted by conflicting anti-coagulating drugs that thin the blood instead. But now scientists have developed a promising new hydrogel infused with snake venom that is drawn to the wound and shuts down bleeding in a matter of seconds.Read More

New silicon-based anode set to boost lifetime and capacity of lithium-ion batteries

A new approach developed by researchers at the University of Waterloo could hold the key to greatly improving the performance of commercial lithium-ion batteries. The scientists have developed a new type of silicon anode that would be used in place of a conventional graphite anode, which they claim will lead to smaller, lighter and longer-lasting batteries for everything from personal devices to electric vehicles.Read More

Forensic scientists gather steam in creating an alternative to luminol

If you've watched any of the various CSI TV shows, then you'll already be familiar with luminol. It's a chemical that, when sprayed onto trace amounts of blood that aren't visible to the naked eye, causes that blood to glow a pale blue. Unfortunately, however, the application of luminol and its reagent chemically compromises the crime scene, plus the glow can't be seen outdoors in sunlight. That's why scientists at the University of South Carolina are exploring the use of an innocuous alternative substance … steam.Read More
