A new MIT study has examined the possibility of acoustic-gravity waves – high-speed sound waves often generated by underwater earthquakes and landslides – acting as an early warning of tsunamis and rogue waves. Read More
When you inflate a balloon and then release it without tying the valve shut, it certainly shoots away quickly. Octopi utilize the same basic principle, although they suck in and then rapidly expel water. An international team of scientists have now replicated that system in a soft-bodied miniature underwater vehicle, which could pave the way for very quickly-accelerating full-size submersibles.

New software developed at Nationwide Children's Hospital in Ohio can take raw sequence data on a person's genome and search it for disease-causing variations in a matter of hours, which its creators claim puts it ahead of the pack as the fastest genome analysis software around. They believe that this makes it now feasible to do large-scale analysis across entire populations. Read More
In most pumps, either a spinning impeller pulls liquid in and then essentially "throws" it out via centrifugal force, or a rotor draws it through using peristaltic force. After studying how birds' flapping wings use fluid dynamics to push air back while moving the animals forward, however, two scientists from New York University have developed a pump that works in yet another fashion – and it has teeth.

Claimed to be the greatest lack of evolution ever discovered, a deep-sea microorganism – sulfur bacteria – recently uncovered by an international group of scientists is reported not to have evolved for more than 2 billion years. Despite it appearing to be an aberration in nature, researchers say that the microscopic creature’s unchanging nature actually supports Charles Darwin’s theory of evolution. Read More
Zymomonas mobilis bacterium might be tricky to say, but this bioethanol-producing microbe could become a household name if Indiana University biologists have their way. The biologists claim have found a quicker, cheaper, cleaner way to increase bioethanol production in this microorganism by using the most abundant element in the Earth’s atmosphere: nitrogen gas (N2). By replacing chemical fertilizers with N2, production costs could be slashed and cellulose ethanol derived from wood pulp made much more economically viable – so much so that the researchers believe it may compete with corn ethanol and gasoline on price.

Just two days after opening, The London Millennium Footbridge was closed to eliminate its sway. Turns out staying with the sway would have had its benefits, as researchers have found that it reduces the amount of energy expended when walking across the bridge. Read More

Keeping ourselves upright is something most of us shouldn't need to think a whole lot about, given we've been doing it almost our entire lives. But when it comes to dealing with more precarious terrain, like walking on ice or some sort of tight rope, you might think some pretty significant concentration is required. But researchers have found that even in our moments of great instability, our subconsciousness is largely responsible for keeping us from landing on our backsides. This is due to what scientists are describing as a mini-brain, a newly mapped bunch of neurons in the spinal cord which processes sensory information and could lead to new treatment for ailing motor skills and balance.

In spite of substantial scientific investigation and convincing indirect evidence, dark matter still eludes direct detection and its existence essentially remains a tantalizing, but unproven, hypothesis. Notwithstanding this, nearly 85 percent of the predicted mass of the universe remains unaccounted for, and dark matter theory is still the prime contender to explain where it may be. Researchers at the University of Southampton have theorized the existence of a new "lighter" dark matter particle in an effort to help unravel the mystery. Read More
In order to study how young fish such as salmon are affected by swimming through hydroelectric dams, scientists have traditionally equipped them with surgically-implanted acoustic tracking tags. Unfortunately, the implantation procedure can harm the fish, plus the weight of the device can affect their behavior. Now, however, a team at the Pacific Northwest National Laboratory (PNNL) in Washington state has developed a much lighter acoustic tag, that can be injected into fish using a needle. Read More
