Leafy greens can prevent the ill-effects of toxins in foods like peanut butter The age old reminder to always eat your greens isn't just for kids anymore. Not only are the vitamins and minerals good for you, but eating greens could also save your life, according to a recent study involving scientists from Lawrence Livermore National Laboratory (LLNL). LLNL researchers Graham Bench and Ken Turteltaub found that giving someone a small dose of chlorophyll (Chla) or chlorophyllin (CHL) "”...

By producing some of the highest resolution images of peptides attaching to mineral surfaces, scientists have a deeper understanding how biomolecules manipulate the growth crystals. This research may lead to a new treatment for kidney stones using biomolecules. The research, which appears in the Nov. 23 online edition of the journal Proceedings of the National Academy of Science, explores how peptides interact with mineral surfaces by accelerating, switching and inhibiting their growth. The...

Report on new materials calls for renewed efforts to regain US leadership in field According to a recent report by the National Research Council of the National Academy of Sciences, the United States, once the world leader in the discovery and growth of crystalline materials, is now falling behind other nations. Citing a decline in large U.S. industrial research laboratories and new investment by foreign governments as the cause behind this slippage, the report also singles out the U.S....

Critical to understanding inertial confinement fusion For years scientists have struggled with the difficult physics of inertial confinement fusion. This is the attempt to compress a target capsule containing isotopes of hydrogen with high-powered lasers to high enough pressure and temperature to initiate fusion burn. To achieve fusion scientists must put as much laser energy on target as possible, a task complicated by energy loss due to laser backscatter, or reflection. Fusion is the basic...

Using numerical hydrodynamic computer simulations, Lawrence Livermore scientists Willy Moss and Michael King, along with University of Rochester colleague Eric Blackman, have discovered that nonlethal blasts can induce enough skull flexure to generate potentially damaging loads in the brain, even without direct head impact.Traumatic brain injury (TBI) results from mechanical loads in the brain, often without skull fracture, and causes complex, long-lasting symptoms.TBI in civilians is usually...

The Lawrence Livermore Laboratory in California could face fines and penalties over its use of the hazardous material beryllium, a federal official says. John Belluardo, a spokesman for the National Nuclear Security Administration, said the enforcement actions could come about if the federal agency determines the lab in Livermore, Calif., violated Energy Department regulations, the Contra Costa Times said Monday. Belluardo said preliminary findings by his agency determined the Lawrence...

Americans used more solar, nuclear, biomass and wind energy in 2008 than they did in 2007, according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory. The nation used less coal and petroleum during the same time frame and only slightly increased its natural gas consumption. Geothermal energy use remained the same. The estimated U.S. energy use in 2008 equaled 99.2 quadrillion BTUs ("quads"), down from 101.5 quadrillion BTUs in 2007. (A BTU or...

On Friday, a U.S. weapons lab unveiled a super laser with the power to burn as hot as a star. The National Ignition Facility's main purpose for the tool is to gauge the reliability and safety of the U.S. nuclear-weapons arsenal, but scientists say it could deliver breakthroughs in safe fusion power. "We have invented the world's largest laser system," actor-turned-governor Arnold Schwarzenegger said during a dedication ceremony attended by thousands including state and national officials. "We...

Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
