Scientists Peg Data’s Speed Limit

April 22, 2004

Scientists say they’ve discovered an apparent speed limit on the scale of picoseconds (10^-12 seconds) — about 1,000 times faster than today’s state-of-the-art (gigabits per second) data-storage devices — that will restrict how quickly data can be written onto disks and then retrieved.

Scientists pinpoint fats danger

May 6, 2009

Columbia University scientists have identified a genetic mechanism that appears to determine which fatty deposits in the arteries have the potential to kill us.

Scientists Ponder the Successor to Moore’s Law

February 18, 2008

The National Science Foundation has requested $20 million from the U.S. government for fiscal 2009 to start the “Science and Engineering Beyond Moore’s Law” effort, which would fund academic research on technologies including carbon nanotubes, quantum computing and massively multicore computers.

Scientists predict Earth-like planets around most stars

February 5, 2015

Planetary scientists have calculated that there are hundreds of billions of Earth-like planets in our galaxy which might support life.

The new research, led by PhD student Tim Bovaird and Associate Professor Charley Lineweaver from The Australian National University (ANU), made the finding by applying a 200 year old idea called the Titius-Bode relation — used to predict the existence of… read more

Scientists present method for entangling macroscopic objects

October 30, 2006

Scientists have developed a theoretical model using entanglement swapping in order to entangle two micromechanical oscillators.

One potential use for entanglement swapping is in quantum repeaters for future quantum computers, which would amp up the signal over long distances to prevent it from being buried by noise and dying out.

Scientists Prevent Brain-Cell Suicide to Keep Birds Singing

July 11, 2008

University of Washington researchers have learned how to temporarily stop seasonal (natural) cell-death processes in birds by inhibiting enzymes called capases.

Neurons used for singing during the mating season die off after the season is over. When the researchers used hormones to inhibit the capases, the song-control regions of the bird’s brains were preserved.

Since cell-death mechanisms are similar across species, the research could lead to new methods… read more

Scientists print cheap RFID tags on paper

February 13, 2012

RFID Chip

A technique for printing radio frequency identification (RFID) chips on paper has been developed by University of Montpellier scientists.

The technique uses a thermal evaporation process to deposit thin aluminium coil antennas on sheets of paper, which can later be used for packaging or printed material. The researchers claim this is a cheaper way to produce RFID tags, allowing the technology to replace both barcodes and QR codes.

Scientists produce carbon nanotubes using commercially available polymeric resins

February 8, 2008

Naval Research Laboratory scientists have produced carbon nanotubes in high yields in bulk solid compositions using commercially available aromatic containing resins.

The solid-state method enables the large-scale production of multi-walled carbon nanotubes in moldable solid forms, films, and fibers using low-cost precursors and equipment and could be less expensive than conventional methods, such as chemical vapor deposition.

Scientists produce neurons from human skin

February 23, 2007

Scientists from Universite Laval’s Faculty of Medicine have succeeded in producing neurons in vitro, using stem cells extracted from adult human skin.

This breakthrough could eventually lead to revolutionary advances in the treatment of neurodegenerative illnesses such as Parkinson’s disease.

Scientists Program Blood Stem Cells To Become Vision Cells

August 3, 2009

University of Florida researchers have programmed bone marrow stem cells to build retinal pigment epithelial cells by mimicking the body’s natural signaling channels with chemicals instead of genetic manipulation.

Scientists propose new hypothesis on the origin of life

September 4, 2009

Life on Earth originated at photosynthetically-active porous structures made of zinc sulfide, similar to deep-sea hydrothermal vents, under the high pressure of a carbon-dioxide-dominated atmosphere, suggest scientists from the University of Osnabrueck, Germany and U.S. National Institutes of Health.

Scientists provide explanation for how cancer spreads

April 30, 2008

Metastasis, the spread of cancer throughout the body, can be explained by the fusion of a cancer cell with a white blood cell in the original tumor, according to Yale School of Medicine researchers.

Scientists put backpacks on dragonflies to track their brains in flight

June 18, 2013

Neuroscientist Anthony Leonardo created the tiny dragonfly backpack above to study how circuits of neurons do rapid computations to catch a mosquito in air, Wired reports.

Electrodes inserted into the dragonfly’s body and brain record the electrical activity of neurons, and a custom-made chip amplifies the signals and transmits them wirelessly to a nearby computer.

The researchers came up with a clever solution to… read more

Scientists Quantify Nanoparticle-Protein Interactions

January 14, 2010

National Institute of Standards and Technology researchers have quantified the interaction of gold nanoparticles with important proteins found in human blood, an approach that should be useful in the development of nanoparticle-based medical therapies and for better understanding the physical origin of the toxicity of certain nanoparticles.

Scientists raise spectre of gene-modified athletes

November 30, 2001

We may be watching genetically-modified (GM) athletes as soon as the Beijing Olympics in 2008, researchers say. Gene doping, in which athletes could genetically modify themselves with performance-enhancing DNA, will be almost impossible to detect, according to Peter Schjerling at the Copenhagen Muscle Research Centre in Denmark.
Schjerling believes cheats will avoid detection by injecting themselves with copies of genes naturally present in the body, such as those encoding growth… read more
