Researchers at The University of Tennessee are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere. Jeremy Smith, UT-ORNL Governor’s Chair and an expert in computational biology, is part of the team that is trying to engineer enzymes — called bioscavengers — so they work more efficiently against chemical weapons.
Every day thousands of people around the world have their lives saved or improved thanks to someone giving blood. But imagine how many more lives could be saved if a long-lasting blood substitute could be found, which could easily be stored at room temperature and available to all patients, regardless of their blood type. This is the challenge a team of scientists at the University of Essex are hoping to overcome with their Haem02 project
Researchers have developed biomaterials for bone regeneration from beer brewing waste. The waste obtained from the beer brewing process contains the main chemical components found in bones (phosphorus, calcium, magnesium and silica). After undergoing modification processes, this waste can be used as support or scaffold to promote bone regeneration for medical applications, such as coating prosthesis or bone grafts.
LEGO has announced that a female minifigure set, featuring three scientists along with their lab gear, will be released as the next LEGO Ideas set. This “Research Institute” model is an official set of all-female scientist figures — a paleontologist, an astronomer and a chemist — made with regular LEGO minifigures.
A team of researchers has developed sperm-inspired microrobots, which can be controlled by oscillating weak magnetic fields. The 322 micron-long robots consist solely of a head coated in a thick cobalt-nickel layer and an uncoated tail. When the robot is subjected to an oscillating field of about the strength of a decorative refrigerator magnet, it experiences a magnetic torque on its head, which causes its flagellum to oscillate
A grandfather clock is, on its surface, a simple yet elegant machine. Tall and stately, its job is to steadily tick away the time. But a look inside reveals a much more intricate dance of parts, from precisely-fitted gears to cable-embraced pulleys and bobbing levers. Like exploring a clock's the inner workings, researchers are digging into the inner workings of the tiny cellular machines that help make all of the proteins our bodies need.
Nine scientists won awards May 29, 2014, for theories about the first moments of the universe, discoveries about the brain and techniques to let researchers see ever-tinier things. The winners, announced by the Norwegian Academy of Science and Letters, will share three $1 million Kavli Prizes. Awarded biennially since 2008, the prizes are named after philanthropist Fred Kavli, a native of Norway. Kavli died last November.
Britain is offering 10 million pounds (almost $17 million) to whoever can solve one of humanity's biggest scientific challenges — once the public has decided what it is. The Longitude Prize is inspired by a 1714 contest to find a way of pinpointing a ship's location at sea. John Harrison's winning invention, the marine chronometer, revolutionized navigation.
Scientists have developed a sophisticated computer modelling simulation to explore how cells of the fruit fly react to changes in the environment. The research is part of an on-going study that is investigating how external environmental factors impact on health and disease. The model shows how cells of the fruit fly communicate with each other during its development.
Researchers are spinning inspiration from spider silk — this time to create more efficient and stronger commercial and biomedical adhesives that could, for example, potentially attach tendons to bones or bind fractures. The scientists created synthetic duplicates of the super-sticky, silk “attachment discs” spiders use to attach their webs to surfaces.
Scientists showed that people who have a variant of a longevity gene, called KLOTHO, have improved brain skills such as thinking, learning and memory regardless of their age, sex, or whether they have a genetic risk factor for Alzheimer’s disease. Increasing KLOTHO gene levels in mice made them smarter, possibly by increasing the strength of connections between nerve cells in the brain.
It’s the sort of thing you would expect Dr Who to do – join up someone’s damaged nerves by using a sonic screwdriver. But the scientists at the University of Glasgow are no time-travellers and their work is based in a lab — not a Tardis. Their research shows that cell patterning using a specific kind of sonic screwdriver — a Heptagon Acoustic Tweezer — may soon be in a position to deliver important results.
For the first time ever, a group of researchers has sequenced the genome of the spider. This knowledge provides a much more qualified basis for studying its features. It also shows that humans share certain genomic similarities with spiders. The fact that the eight-legged creepy spider in some ways resembles humans is one of the surprising conclusions ...
The long-fingered bat is on the verge of extinction and work by biologist Ostaizka Aizpurua has been crucial in getting to know it better to be able to take the necessary steps to protect it. Thanks to this work, the long-fingered bat has been shown to feed on fish as well as insects. What is more, it knows how to fish.
GeneMarker software includes an integrated replicate comparison tool for use in ecology, agricultural and clinical research. The tool automatically groups replicate samples within a project and provides immediate flagging to notify researchers of any discordant allele calls.
In the movies, humans often fear invaders from Mars. These days, scientists are more concerned about invaders to Mars, in the form of micro-organisms from Earth. Three recent scientific papers examined the risks of interplanetary exchange of organisms using research from the International Space...
Stanford bioengineers have developed faster, more energy-efficient microchips based on the human brain — 9,000 times faster and using significantly less power than a typical PC. This offers greater possibilities for advances in robotics and a new way of understanding the brain. For instance, a chip as fast and efficient as the human brain could drive prosthetic limbs with the speed and complexity of our own actions.
