Barnacle glue, or cement, sticks to any surface, under any conditions. And it’s still far better than anything we have been able to develop synthetically. Now, over 150 years since it was first described by Charles Darwin, scientists are finally uncovering the secrets behind the super strength of barnacle glue.
A Univ. of Alabama start-up company, 525 Solutions, has received about $1.5 million from the federal government to refine an invention to extract uranium from the ocean for use as fuel. It is an adsorbent, biodegradable material made from the compound chitin, which is found in crustaceans and insects. The researchers have developed transparent sheets, or mats, comprised of tiny chitin fibers, which pull uranium from the water.
Yale School of Medicine and Yale Cancer Center researchers have uncovered a genetic vulnerability of cancer cells that express telomerase and showed that telomerase-expressing cells depend upon a gene named p21 for their survival. Authors found that simultaneous inhibition of both telomerase and p21 inhibited tumor growth in mice.
New Star Environmental has introduced the Frog-4000, a fully contained purge and trap gas chromatography (GC) system. The handheld GC is designed for real-time portable analysis of VOCs in water, soil and air. The unit can be used as a portable GC PID for environmental testing in the field, in a mobile lab, portable lab or in a commercial environmental lab.
Supercritical Fluid Technologies has introduced a new, high-pressure reactor designed for small batch reaction chemistry. The HPR-Micro Reactor come standard with a 10-mL Iconel 718 reactor vessel for operation up to 10,000 psi (689 bar/68.9 MPa), inlet and outlet valves and a pressure gauge.
Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian rhythms, or the “biological clock” found in most life forms. The ability of lipoic acid to help restore a more normal circadian rhythm to aging animals could explain its apparent value in so many important biological functions.
Russian scientists say they believe a 66-yard wide crater discovered recently in far northern Siberia could be the result of changing temperatures in the region. Andrei Plekhanov, a senior researcher at the Scientific Research Center of the Arctic who visited the crater this week, the crater was mostly likely the result of a "build-up of excessive pressure" underground due to rising temperatures.
Lawrence Livermore National Laboratory scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside our solar system. Researchers can now re-create and accurately measure material properties that control how these planets evolve over time, information essential for understanding how these massive objects form.
Ultra-fast x-ray laser research led by Kansas State Univ. has provided scientists with a snapshot of a fundamental molecular phenomenon. The finding sheds new light on microscopic electron motion in molecules. The researchers measured at which distances between the two atoms the electron transfer can occur.
One of the major road blocks to the design and development of new, more efficient solar cells may have been cleared. Researchers with the Lawrence Berkeley National Laboratory have developed the first ab initio method for characterizing the properties of “hot carriers” in semiconductors. Hot carriers are electrical charge carriers with significantly higher energy than charge carriers at thermal equilibrium.
Nearly all electronics require devices called oscillators that create precise frequencies. For nearly 100 years, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. However, future high-end navigation systems, radar systems and even possibly tomorrow's consumer electronics will require references beyond the performance of quartz.
Researchers at the Univ. of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light (for example, distances less than ~600 nm for red light). A standard optical microscope acts as a “nanocamera” whereas the pBNAs are the analogous film.
Twisting a screwdriver, removing a bottle cap and peeling a banana are just a few simple tasks that are tricky to pull off single handedly. Now a new wrist-mounted robot can provide a helping hand—or rather, fingers. Researchers at Massachusetts Institute of Technology have developed a robot that enhances the grasping motion of the human hand.
The possibility that the civilian jetliner downed over war-torn eastern Ukraine with nearly 300 people onboard was hit by a missile could have profound consequences for the world's airlines. Airlines might have to be more vigilant about avoiding trouble spots, making flights longer and causing them to burn more costly fuel. They may even be forced to reconsider many international routes.
Microsoft announced the biggest layoffs in its history Thursday, saying it will cut 18,000 jobs or 14 percent of its workforce as it streamlines its Nokia mobile device business to focus on using the Windows Phone operating system. Although the job cuts had been expected, the extent of them was a surprise.
