Vitamin D casts cancer prevention in new light

April 29, 2007

Cancers in rich countries isn’t caused mainly by pollutants but by a vitamin D deficiency, research suggests.

Researchers are linking low vitamin D status to a host of other serious ailments, including multiple sclerosis, juvenile diabetes, influenza, osteoporosis and bone fractures among the elderly.

A four-year clinical trial involving 1,200 women found those taking the vitamin had about a 60-per-cent reduction in cancer incidence, compared with those who… read more

MRI used to detect lone electron

July 15, 2004

Magnetic resonance imaging has been used to pinpoint the position of a single, unpaired electron for the first time.

The achievement, by a team at IBM’s Almaden Research Laboratory in San Jose, California, paves the way for scientists to map the shape of molecules and peer inside transistors to examine atomic-scale features.

“This is an impressive milestone and an essential step towards imaging biomolecules in three dimensions,” says… read more

Mgestyk system promises gesture control on the cheap

November 10, 2008

Mgestyk Technologies has developed a gesture-based control system using nothing more than an “affordable 3D camera” and some custom software to capture even small hand gestures.

Nano-crystal ‘gems’ are powerful chemical catalysts

May 4, 2007

Georgia Institute of Technology researchers have grown 24-sided platinum nanocrystals that have the most reactive surfaces yet, allowing them to catalyse reactions with ethanol about two to four times faster than platinum nanospheres.

Improved ability to oxidize chemicals like ethanol could have a big impact on the development of hydrogen fuel cells, which use platinum to oxidize compounds and generate electricity.

UK study calls for extra safety measures for nanotechnology

July 30, 2004

The UK’s Royal Society and Royal Academy of Engineering today released their long-awaited report on the potential risks and benefits of nanotechnology. The report proposes:

  • UK and European legislation should treat nanoparticles and nanotubes as new chemicals and avoid release of such nanomaterials into the environment until more is known about their impact.
  • Set lower exposure levels for people who work with manufactured nanoparticles.

    Study predicts nanoscience will greatly increase efficiency of next-generation solar cells

    August 13, 2010

    Incorporating quantum dots and photovoltaics into solar cells could increase the efficiency of present-day solar cells by a very significant amount of 50-100%, while lowering the capital cost of solar cell production, according to an analysis by Arthur Nozik, a researcher at the National Renewable Energy Laboratory (NREL) and professor at the University of Colorado.

    Google Adds Searching by Voice to iPhone Software

    November 14, 2008

    Google researchers have added sophisticated voice recognition technology to the company’s search software for the Apple iPhone, with plans to offer it for other phones.

    AMAT tools up really big solar panels

    May 16, 2007

    Signet is aiming its panels at larger scale solar installations: about 20MW of panels to be made in 2008, growing to 60MW or so once capacity has fully ramped.

    Currently, solar panels are in the $8-9/W range installed. Signet hopes to bring that down to $3/W by 2010. The goal is to have $1.25/W panels when production starts in 2008, and drop that to sub-$1 by 2010.

    RNA could form building blocks for nanomachines

    August 11, 2004

    Researchers have coaxed RNA to self-assemble into 3-D arrays, a potential backbone for nanotech scaffolds. These RNA structures can form a wider variety of shapes than double-stranded DNA can and are easier to manipulate than many protein alternatives.

    Peixuan Guo of Purdue University and his colleagues report the findings in the August 11, 2004, issue of the journal Nano Letters.

    By mixing the custom-made RNA strands with other… read more

    Robots learning from experience

    Software that enables robots to move objects around a room, building up knowledge about their environment, is being developed by robotics researchers at the EU-funded Xpero project.

    Breakthrough Nanotechnology Will Bring 100 Terabyte 3.5-inch Digital Data Storage Disks

    August 16, 2004

    100 terabytes of data on a 3.5-inch disk may be possible with a new technique for creating an “Atomic Holographic DVR” disc drive within five years, priced at $570 to $750 with the replacement discs for $45.

    Electron strobe turns atoms into movie stars

    November 22, 2008

    California Institute of Technology chemist Ahmed Zewail has developed a way to see picosecond motion at a subatomic scale, producing high-resolution footage of atoms in motion with a transmission electron microscope (TEM).

    Google has added interactive photographic street views to Google Maps in portions of certain cities.

    The Ups and Downs of Nanobiotech

    August 30, 2004

    Ten years from now, a visit to the doctor could be quite different than it is today. How different? Imagine tiny particles that “cook” cancers from the inside out; “smart bomb” drugs that detonate only over their targets; and finely structured scaffolds that guide tissue regeneration.

    Academic labs, small startups, and giant pharmaceutical companies are working to turn these proofs-of-principle into approved therapies.
