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

Support bath enables 3D printing of soft biomaterials

When it comes to surgical procedures on internal organs, the heart can be one of the most difficult to work with. Heart tissue doesn't repair itself like that of other body parts, so those with failing hearts only have the option of joining a long waitlist in hopes of receiving a transplant in time. All of this may change in the near future, as a research group at Carnegie Mellon University has demonstrated a method of 3D bioprinting with soft materials.Read More

Review gives NASA's Space Launch System the tick of approval

The first of three planned configurations of NASA's Space Launch System (SLS), known as Block 1, has completed and passed the final Critical Design Review (CDR). This is the fourth and final review focusing on the concept and design of NASA's first man-rated launcher since the Space Shuttle and paves the way for full-scale fabrication of the first exploration-class rocket since the Saturn V and the most powerful rocket ever built.Read More

Wendelstein 7-x stellarator puts new twist on nuclear fusion power

In a large complex located at Greifswald in the north-east corner of Germany, sits a new and unusual nuclear fusion reactor awaiting a few final tests before being powered-up for the very first time. Dubbed the Wendelstein 7-x fusion stellarator, it has been more than 15 years in the making and is claimed to be so magnetically efficient that it will be able to continuously contain super-hot plasma in its enormous magnetic field for more than 30 minutes at a time. If successful, this new reactor may help realize the long-held goal of continuous operation essential for the success of nuclear fusion power generation.Read More
