The discovery of a major gear in the biological clock that tells the body when to sleep and metabolize food may lead to new drugs to treat sleep problems and metabolic disorders, including diabetes.

Scientists at the Salk Institute for Biological Studies, led by Ronald M. Evans, a professor in Salk’s Gene Expression Laboratory, showed that two cellular switches found on the nucleus of mouse… read more

Salmon DNA-based memory device

February 6, 2012


Researchers from Karlsruhe Institute of Technology (KIT) in Germany and the National Tsing Hua University in Taiwan have created a DNA-based “write-once-read-many-times” (WORM) memory device to achieve more cost-effective data storage.

The device consists of a thin film of salmon DNA embedded with nano-sized particles of silver and then sandwiched between two electrodes. To store information, ultraviolet light is used to make the silver atoms cluster… read more

Salmonella Bacteria Turned Into Cancer Fighting ‘Robots’

March 31, 2008

University of Massachusetts Amherst researchers are turning Salmonella bacteria into tumor killing “robots” that use their flagella to go deep into tumors where conventional chemotherapy can’t reach, and once in place, manufacture drugs that trigger cancer cells to kill themselves.

Normally, mice with tumors all die within 30 days. After receiving this bacterial system and getting a dose of radiation, all the mice in their lab tests survived beyond… read more

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 Boasts Fastest Ever Multimedia RAM

January 25, 2005

Samsung Electronics has today begun mass production of what it claims is the world’s fastest RAM for multimedia applications.

Samsung’s 256Mb XDR (eXtreme Data Rate) DRAM is 10 times faster than DDR 400 memory and five times faster than RDRam (PC800), Samsung claims.

Samsung plans to introduce a 512Mb XDR DRAM, capable of transferring data as fast as 12.8Gbps, during the first half of this year.

Samsung Demonstrates First Color Carbon Nanotube-Based Electrophoretic Display

October 20, 2008

Samsung Electronics is demonstrating the first carbon-nanotube-based color active matrix electrophoretic display e-paper device.

Electrophoretic displays offer advantages over traditional flat panel displays: their low power consumption and bright light readability makes them well suited for handheld and mobile applications; they can be produced on thin, flexible substrates, making them ideally suited for use in e-paper applications; and rely on reflected light and can retain text or images without… read more

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.

Samsung windfall: all of South Korea’s textbooks to go digital by 2015

By 2014, all of South Korea’s elementary-level educational materials will be digitized, and by 2015, the entire school-age curriculum will be delivered on an array of computers, smart phones and tablets.

The makers of the Kno tablet made a pretty good case that if we’re going to replace textbooks with their digital equivalent, we need devices with something like four times the screen territory of the iPad.

Samsung’s gun-toting robot

December 5, 2006

The Intelligent Surveillance and Security Guard Robot, being developed by Samsung, will guarantee “perfect guarding operation,” in contrast with human guards who are all too prone to succumb to fatigue or inclement weather.

It has two cameras–one for daytime watch and another, infrared one for the night–and a laser rangefinder.
