Scientists are increasingly looking at using medication-filled microspheres for targeted drug delivery within the human body. Silicone would
be a particularly good building material for such spheres, as it's
biocompatible, waterproof, and chemically stable. Unfortunately, using
traditional methods, it can't be made into small enough spheres. Now,
however, a new process has allowed for the creation of silicone
microspheres that are about one one-hundredth the size of any previously
Doing your hair and brushing your teeth are chores that may become a
little more interesting and fun with a new mirror that, besides
reflecting, can also display emails, news threads, tweets, public
transport times and all kinds of online data. That's because a student
team from the College of Science and College of Engineering at Purdue
University has created a mirror that doubles as an information
interface. Keeping up-to-date with bus schedules inspired the team to
come up with the info-mirror.
The unmanned Progress 59 (M-27M) cargo spacecraft has burned up somewhere over the central Pacific ocean according to the Russian Federal Space Agency. Launched 10 days ago, it failed to reach the ISS due to a malfunction that prevented mission control from establishing contact shortly after launch.
Around one week after it smashed spectacularly into Mercury, NASA's MESSENGER probe has posthumously turned up valuable observations revealing some of the planet's long-held secrets. Using data gleaned from the spacecraft's closest pass of the planet earlier this year, scientists have established its magnetic field to be almost 4 billion years old, shedding new light on how Mercury has evolved over its 4.5 billion year lifespan.
In order to confirm that a patient presenting with a heart attack has in
fact had one, doctors typically use bulky, expensive lab equipment ...
which isn't always available to clinicians in developing nations or
rural locations. That's why scientists from Korea's Pohang University of
Science and Technology have created a simple thermometer-like device
that reportedly does the job.
The European Space Agency (ESA) has announced that its Proba-V satellite has successfully picked up signals from thousands of aircraft around the globe. The findings of the mission, which was primarily tasked with watching changes in vegetation across the planet, could pave the way for a more accurate air traffic control system.
In Africa, the spread of parasitic worms known as Loa loa is seriously hindering the efforts of health care workers to cure particular rampant diseases. Though there are drugs available to treat both river blindness and lymphatic filariasis, if they are administered to a patient who also happens to also be infected with Loa loa the consequences can be lethal. This is complicated further by the inherent difficulties in screening for the worms, but a newly developed mobile phone microscope needing only a drop of blood to automatically detect the parasite promises to make things a whole lot simpler.
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.
