Mussels have an incredible ability to cling to wet surfaces. It's an ability that scientists are trying to replicate
for use in man-made adhesives. That adhesion can't be turned on and off
as needed, however, limiting its potential applications. That's where
the Northern clingfish comes in. It can suck onto rough, slimy surfaces,
supporting up to 150 times its own body weight when lifted. That said,
it can also just let go and swim away whenever it wants. Scientists from
the University of Washington now understand how it's able to do so, and
are looking at applying the principle to fields such as surgery and
Mornings on the International Space Station (ISS) got a bit brighter as the first cup of espresso coffee
in space was brewed and drank on the station by Italian astronaut
Samantha Cristoforetti. To celebrate, Cristoforetti tweeted back to
Earth a photo of her imbibing the brew, saying, "'Coffee: the finest
organic suspension ever devised.' Fresh espresso in the new Zero-G cup!
To boldly brew…"
SpaceX has carried out a successful test of its Launch Abort System (LAS) for the Crew Dragon spacecraft. The test, which took place at Space Launch Complex 40 of the Cape Canaveral Air Force Station represents a major stop towards getting the spacecraft human rated under the Commercial Crew Transportation Capability (CCtCap) contract. NASA hopes that commercial spacecraft such as the Crew Dragon will return manned spacecraft launches back to American soil sometime in 2017.
A key battleground in the fight against cancer has been the development of vaccines to stop tumors taking hold. These are intended to kick the body's own immune system into action to fend off the cancerous cells, with immunotherapy drugs for melanomas, prostate and lung cancer all emerging in recent years. But one hurdle oncologists are yet to tackle with any great success is a vaccine for breast cancer. New research now suggests this mightn't be all that far away, with the discovery that loading cancer antigens into silicon microparticles serves to greatly boost the immune response.
Restarting the world's largest particle accelerator after a two-year overhaul isn't just a matter of throwing a switch and making sure the lights go on. It's an eight-week process of baby steps – one's that involve billions of electron volts. But the Large Hadron Collider (LHC) took a major step forward this week as the CERN team fired up two counter-rotating proton beams that were injected into the LHC using the Super Proton Synchrotron, then accelerated to an energy of 450 GeV each.
Researchers at the University of California, Davis have developed and tested a molecule that has the ability to disrupt the body's regulation of cancer cells, causing the cells to self-destructing rather than multiply. The method was found to be effective when tackling dormant brain cancer cells that existing treatments are ineffective at eradicating.
A natural enzyme called catalase may prove hugely significant in treating neurological disorders such as Parkinson's. These extremely potent antioxidants can tackle neuron-killing inflammation with an effectiveness unparalleled by small molecule drugs. But there's a problem, they are big. So big that getting them through the blood-brain barrier for delivery straight to the brain is nearly impossible. But researchers have now discovered that loading them into tiny, naturally occurring bubbles allows them to sneak past the brain's defenses, pointing to the possibility of improved treatments for such conditions.
When the first Orion astronauts stare back at Earth, they'll be looking through windows made mostly of plastic. Because Orion is designed to carry out manned deep-space missions and even a possible Mars voyage, NASA decided it was time to replace the conventional glass windows with panes of acrylic that are lighter, less expensive, and more structurally sound than previous designs, and is more suited to long-duration missions.
If you've ever seen a bat in flight, then you'll know how quickly and
precisely they can maneuver. Scientists from Johns Hopkins University,
Columbia University and the University of Maryland have now uncovered
one of the key factors that allows them to do so – and it could have
applications in the design of aircraft.
