Scientists Move Optical Computing Closer to Reality

August 20, 2008

University of Pennsylvania scientists have theorized a way to increase the speed of pulses of light traveling in nanoparticle chains (acting as miniature waveguides) to 2.5 times the speed of light by altering the particle shape.

As the velocity of the light pulse increases, so too does the operating bandwidth of a waveguide, thus increasing the number of information channels and allowing more information to flow simultaneously through a… read more

Scientists observe brain cell development in ‘real time’

May 24, 2007

For the first time anywhere, a researcher at the Hebrew University of Jerusalem has succeeded in observing in vivo the generation of neurons in the brain of a mammal.

Using special microscopic imaging techniques, combined with virus gene technology, Dr. Adi Mizrahi was able to develop an experimental model to study development of neural dendrites in vivo.

Scientists observe single gene transcription in living cells

April 22, 2011

Researchers at Albert Einstein College of Medicine of Yeshiva University have for the first time observed the activity of a single gene in living cells.

Einstein scientists were able to follow, in real time, the process of gene transcription, which occurs when a gene converts its DNA information into molecules of messenger RNA (mRNA) that go on to make the protein coded by the gene.

Gene transcription… read more

Scientists of Very Small Draw Disciplines Together

February 10, 2003

Nanotechnology, biotechnology, electronics and brain research are converging into a new field of science vital to the nation’s security and economic clout: NBIC (nanotechnology, biotechnology, information technology and cognitive science).

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 plan to build human genome from scratch

June 6, 2016

Efficiency trends in DNA sequencing (green) and synthesis of double-stranded DNA (dsDNA, blue) and single-stranded DNA (ssDNA, red) over the past ~35 years. Double-stranded DNA, or<br />
gene synthesis, has improved noticeably over the past ~10 years, but still lags behind<br />
sequencing and ssDNA synthesis. The disruptive improvement in sequencing and ssDNA (oligonucleotides) synthesis technologies has improved from multiplex and miniaturization technologies in high-throughput DNA sequencing and oligo microarray technologies, respectively. Commercial gene synthesis technologies relies on both oligo synthesis (building blocks) and sequencing (validation of synthesis) technologies. (credit: Jef D. Boeke/Science)

Leading genomics experts have announced Genome Project-write (HGP-write), which aims to synthesize entire genomes of humans and other species from chemical components and get them to function in living cells.

As explained in Science, the goal of HGP-write is to reduce the costs of engineering large genomes, including a human genome, and to develop an ethical framework for genome-scale engineering and transformative medical applications.

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

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


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.
