One Yellow Fever Shot is Enough

The World Health Organization says a yellow fever booster vaccination given 10 years after the initial shot isn’t necessary.

The U.N.’s global health agency said today that its expert group on immunization believes a single dose of vaccination is sufficient to confer lifelong immunity against the disease.

Physics Principles Can Be Observed in Bowls of CerealAndong He saw a phenomenon at work in his breakfast bowl that he couldn’t explain. It prompted this question: how does cereal shape influence the way cereals floating in the milk join? The Yale postdoctoral student offers an answer, along with collaborators Khoi Nguyen and Shreyas Mandre of Brown Univ., in a paper published in Europhysics Letters.“Two floating objects, when they attract each other, will try to maximize the area of contact,” says He, of Yale’s Department of Geology & Geophysics. “Think about two ellipses — instead of tip to tip, they will try to align so that they are side to side.”Read more: http://www.laboratoryequipment.com/news/2013/05/physics-principles-can-be-observed-bowls-cereal

Organic Food Gains Political Clout

The organic food industry is gaining clout on Capitol Hill, prompted by rising consumer demand and its entry into traditional farm states. But that isn’t going over well with everyone in Congress.

Tensions between conventional and organic agriculture boiled over this week during a late-night House Agriculture Committee debate on a sweeping farm bill that has for decades propped up traditional crops and largely ignored organics.

Mars Rover Breaks 40-Year-Old RecordWhile Apollo 17 astronauts Eugene Cernan and Harrison Schmitt visited Earth’s moon for three days in December 1972, they drove their mission’s Lunar Roving Vehicle 19.3 nautical miles (22.210 statute miles or 35.744 kilometers). That was the farthest total distance for any NASA vehicle driving on a world other than Earth until yesterday.The team operating NASA’s Mars Exploration Rover Opportunity received confirmation in a transmission from Mars that the rover drove 263 feet (80 meters) on Thursday, bringing Opportunity’s total odometry since landing on Mars in January 2004 to 22.220 statute miles (35.760 kilometers).Read more: http://www.laboratoryequipment.com/news/2013/05/mars-rover-breaks-40-year-old-record

Artificial Forest Splits WaterIn the wake of the sobering news that atmospheric carbon dioxide is now at its highest level in at least three million years, an important advance in the race to develop carbon-neutral renewable energy sources has been achieved. Scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have reported the first fully integrated nanosystem for artificial photosynthesis. While “artificial leaf” is the popular term for such a system, the key to this success was an “artificial forest.”Read more: http://www.laboratoryequipment.com/news/2013/05/artificial-forest-splits-water

Parasites ‘Talk’ to Each Other

Melbourne scientists have made the surprise discovery that malaria parasites can “talk” to each other – a social behavior to ensure the parasite’s survival and improve its chances of being transmitted to other humans.

The finding could provide a niche for developing anti-malarial drugs and vaccines that prevent or treat the disease by cutting these communication networks.

Nanoflowers Blossom from a Chemical Reaction“Spring is like a perhaps hand,” wrote the poet E. E. Cummings: “carefully / moving a perhaps / fraction of flower here placing / an inch of air there… / without breaking anything.”With the hand of nature trained on a beaker of chemical fluid, the most delicate flower structures have been formed in a Harvard laboratory — and not at the scale of inches, but microns. These minuscule sculptures, curved and delicate, don’t resemble the cubic or jagged forms normally associated with crystals, though that’s what they are. Rather, fields of carnations and marigolds seem to bloom from the surface of a submerged glass slide, assembling themselves a molecule at a time.Read more: http://www.laboratoryequipment.com/news/2013/05/nanoflowers-blossom-chemical-reaction

Crowd-Sourcing Helps Monitor Japan’s Radiation

A team of researchers from the Univ. of Southampton has designed a new tool to intelligently combine nuclear radioactivity data in Japan. The technology harnesses the power of crowd-sourced radiation data; an innovative resource that became available after the 2011 Fukushima nuclear disaster.

During March 2011, the second-largest nuclear emergency since Chernobyl 1986 was caused by a magnitude nine Tsunami hitting the North-East coast of Japan and severely damaging the nuclear power plant of Fukushima-Daiichi. The consequent nuclear accident provoked radioactivity increases of up to 1,000 times the normal levels in the area of Fukushima with more than 488,000 people being evacuated from their homes for the risk of nuclear contamination.

Injected Nanogel Can Help Fight DiabetesInjectable nanoparticles developed at MIT may someday eliminate the need for patients with Type 1 diabetes to constantly monitor their blood-sugar levels and inject themselves with insulin.The nanoparticles were designed to sense glucose levels in the body and respond by secreting the appropriate amount of insulin, thereby replacing the function of pancreatic islet cells, which are destroyed in patients with Type 1 diabetes. Ultimately, this type of system could ensure that blood-sugar levels remain balanced and improve patients’ quality of life, according to the researchers.Read more: http://www.laboratoryequipment.com/news/2013/05/injected-nanogel-can-help-fight-diabetes

Earth’s Iron Core is Shockingly WeakThe massive ball of iron sitting at the center of Earth is not quite as “rock-solid” as has been thought, say two Stanford mineral physicists. By conducting experiments that simulate the immense pressures deep in the planet’s interior, the researchers determined that iron in Earth’s inner core is only about 40 percent as strong as previous studies estimated.This is the first time scientists have been able to experimentally measure the effect of such intense pressure – as high as 3 million times the pressure Earth’s atmosphere exerts at sea level – in a laboratory. A paper presenting the results of their study is available online in Nature Geoscience.Read more: http://www.laboratoryequipment.com/news/2013/05/earths-iron-core-shockingly-weak
