DNA Danger From Thirdhand Smoke
2013-06-21 04:52:23

Rebekah Eliason for redOrbit.com – Your Universe Online For the first time ever, thirdhand smoke has been found to cause significant amounts of damage to human cells. Thirdhand smoke is the toxic residue that attaches to almost all surfaces leaving a strong odor long after cigarette smoke has dissipated. The researchers from Lawrence Berkeley National Laboratory also discovered in this study that chronic exposure caused more DNA damage than acute exposure. Samples exposed to chronic...

Scientists Uncover Secrets Of Biological Soil Crust Microbes
2013-06-14 18:39:19

Brett Smith for redOrbit.com — Your Universe Online A new study from the Lawrence Berkeley National Laboratory in Berkeley, California has found the biological soil crust (BSC) layer of a desert contains microbes that lie in wait for the ideal conditions to begin metabolic activity. “We found a way to measure from start to finish in real unaltered samples the molecular events behind the response of cyanobacterium to wetting and drying in a desert BSC,” said...

Researchers Increase NMR/MRI Sensitivity Through Hyperpolarization Of Nuclei In Diamond
2013-06-06 15:09:01

Lawrence Berkeley National Laboratory Today´s nuclear magnetic resonance (NMR) and Magnetic Resonance Imaging (MRI) technologies, like quantum information processing and nuclear spintronic technologies, are based on an intrinsic quantum property of electrons and atomic nuclei called “spin.” Electrons and nuclei can act like tiny bar magnets with a spin that is assigned a directional state of either “up” or “down.” NMR/MRI signals depend upon a...

Improving Ventilation In Schools Could Reduce Illness-Related Absences
2013-06-06 07:47:49

redOrbit staff & Wire Reports — Your Universe Online Making sure that students get enough fresh air in their classrooms could keep kids from missing school due to illness, researchers from the at Lawrence Berkeley National Laboratory (Berkeley Lab) claim in a new study. Writing in the journal Indoor Air, lead author Mark Mendell and his colleagues report that their analysis of over 150 California classrooms revealed that bringing classroom ventilation rates up to state...

Boreal Forests Expected To Shift Poleward
2013-05-06 04:58:49

redOrbit Staff & Wire Reports - Your Universe Online What will happen to the climate in various parts of the world as the effects of global warming become amplified? Researchers from the Lawrence Berkeley National Laboratory have developed a new way to predict what will occur as temperatures rise across the Earth. The research, which was published in Sunday´s online edition of the journal Nature Geoscience, is anticipating major changes for boreal forests, which the authors...

Berkeley Lab Researchers Unveil Technique for Easy Comparisons of Proteins in Solution A revolutionary X-ray analytical technique that enables researchers at a glance to identify structural similarities and differences between multiple proteins under a variety of conditions has been developed by researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab). As a demonstration, the researchers used this technique to gain valuable new...

Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials — artificial nanoconstructs whose optical properties arise from their physical structure rather than their chemical composition. Engineering a unique two-dimensional sheet of gold nanoantennas, the researchers were able to obtain the strongest signal yet of the photonic spin Hall effect, an optical...

Surprising Control Over Photoelectrons From A Topological Insulator
2013-03-13 15:22:44

Lawrence Berkeley National Laboratory Berkeley Lab scientists discover how a photon beam can flip the spin polarization of electrons emitted from an exciting new material Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in the bulk, yet behaves like a metal on its surface. Researchers find TIs exciting partly because the electrons...

Berkeley Lab Team Examines DNA To RNA Transcription
2013-02-28 20:46:25

Alan McStravick for redOrbit.com — Your Universe Online The Human Genome Project, a study intended to map out the structure of the 20,000-25,000 genes in human DNA, was begun in 1990 and concluded in 2003. The project, originally coordinated by the US Department of Energy and the National Institutes of Health, later partnered with the Wellcome Trust in the UK along with scientists from Japan, France, Germany and China. The act of mapping out human DNA and storing it in research...

Tree Death In Amazon Much Higher Than Previously Believed
2013-01-29 12:28:36

Alan McStravick for redOrbit.com - Your Universe Online If a tree falls in the forest and no one is around, does it have a direct impact on climate change? A new study from the Lawrence Berkeley National Laboratory (Berkeley Lab) set out to answer this question. Forests are critical to the equilibrium of Earth´s climate since they absorb large quantities of the greenhouse gas carbon dioxide directly from our atmosphere. The death of a tree, however, reverses the flow of carbon and...
