Salt may affect more than blood pressure: study

April 20, 2007

Consuming less salt can not only lower blood pressure, but may reduce the risk of heart disease overall, Brigham and Women’s Hospital and Harvard Medical School researchers reported.

They found that people with borderline-high blood pressure who reduced their sodium intake by 25 to 35 percent lowered their risk of total cardiovascular disease by 25 percent. And this lower risk lasted for 10 to 15 years.

Samsung to release ’3D’ memory modules with 50% greater density

December 8, 2010

Samsung today announced a new 8GB dual inline memory module (DIMM) that stacks memory chips on top of each other using through silicon via (TSV), which increases the density of the memory by 50% compared to conventional DIMM technology.

Using the TSV technology will greatly improve chip density in next-generation server systems, Samsung said, making it attractive for high-density, high-performance systems. The TSV technology creates micron-sized holes… read more

Samsung unveils ‘world’s smallest’ 256GB SSD drive

May 27, 2008

Samsung Electronics has unveiled a 256GB SSD solid state drive that is less than 10mm thick and 2.4 times faster than traditional hard drives.

Solid state drives provide longer battery life, faster boot times, and reduced weight, allowing notebook makers to slim down their laptops. And the lack of moving parts makes SSDs more rugged.

A Sandia National Laboratories technology has been used to remove radioactive material from more than 43 million gallons of contaminated wastewater at Japan’s damaged Fukushima Daiichi nuclear power plant.

Sandia researchers worked around the clock following the March 2011 disaster to show the technology worked in seawater, which was pumped in to cool the plant’s towers.

Sandia scientists previously found that a certain class… read more

Sandia nuclear-fusion liners break even in tests

September 19, 2012

Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific “break-even” energies or better within the next few years, have functioned successfully in preliminary tests, according to a Sandia research paper accepted for publication by Physical Review Letters (PRL).

To exceed scientific break-even is the most hotly sought-after goal of fusion research, in which the energy released by a fusion reaction is… read more
