Calculating Drugs’ Side Effects

December 18, 2007

A new computational method that searches an enormous database of protein structures could allow researchers to predict a drug’s potential side effects.

The technique, developed by researchers at the University of California, San Diego (UCSD), could also be applied to existing drugs to explain known side effects or to identify additional uses.

New suspect implicated in the development of cancer

June 9, 2005

“MicroRNA” molecules – which differ from ordinary messenger RNA in not carrying information for making proteins – are emerging as key gene switches regulating embryo development and cell replication. Now, new evidence shows mis-regulation of microRNAs might trigger development of cancers.

How spooky is Foursquare?

March 17, 2011

Do you really want people to know where you are, based on your mobile phone’s GPS or a check-in at a Foursquare place? This restaurant story by Brad Feld (Do More Faster) may give you second thoughts.

High Tech Evolves

June 4, 2002

Evolutionary biology is influencing the way we build computers, write software and organize companies. TIME convened a panel of visionaries, including Ray Kurzweil, to address this. Key ideas:

  • Autonomic computing: bio-inspired systems for managing and maintaining computer networks.
  • Evolutionary computing (genetic algorithms) for engineering designs.
  • Software that models the way a community of individuals develops from the diverse decisions of its members — for

    Warm weather may not halt swine flu

    May 8, 2009

    The virus could infect more than a billion people by July and may not be slowed by summer temperatures in temperate countries, based on new data from Mexico and case numbers so far that reveals disturbing similarities with the last H1N1 pandemic, in 1918.

    Google and the Wisdom of Clouds

    December 24, 2007

    Increasing access to computing clouds–globe-spanning network of computers and information such as Google’s–signals a fundamental shift in how we handle information.

    The Google 101 project will spread cloud computing first to a handful of U.S. universities within a year and later deploy it globally.

    Amazon has opened up its own networks of computers to paying customers, initiating new players to cloud computing. Yahoo has opened up a cluster… read more

    Brain Sees Violent Video Games as Real Life — Study

    June 23, 2005

    The brains of players of violent video games react as if the violence were real, a study has suggested.

    It found that as violence became imminent, the cognitive parts of the brain became active and that during a fight, emotional parts of the brain were shut down.

    It suggests that video games are training the brain to react with this pattern.

    Neurons grow into semiconductor tubes: future intelligent chips?

    March 23, 2011

    Nanomembrane Tubes

    Researchers at the University of Wisconsin, Madison, led by Minrui Yu, have successfully induced nerve cell tendrils to grow through semiconductor tubes using strained silicon (Si) and germanium (Ge) nanomembranes as a cell culture substrate.

    In many neural culture studies, neurite migration on a flat, open surface does not reflect the three-dimensional (3D) microenvironment in vivo.

    Their xperiments show that the SiGe substrate and the tube fabrication process… read more

    Science-Technology Drive Is Urged to Fight Terror

    June 25, 2002

    The National Research Council has developed a blueprint for using current technologies and creating new capabilities to reduce the likelihood of terrorist attacks. The recommendations include protecting and controlling nuclear weapons and material, producing sufficient supplies of vaccines and antibodies, securing shipping containers that could hide bombs or toxins, protecting power grids more effectively, improving ventilation systems in public buildings, emergency communications for workers responding to disasters, and more research… read more

    The Next Best Thing to You

    May 18, 2009

    Project LifeLike aims to to create avatars that are as realistic as possible, including 3-D measurements of a person’s form and of movements, natural language, and automated knowledge update and refinement.

    The project is a collaboration between the Intelligent Systems Laboratory at the University of Central Florida and the Electronic Visualization Laboratory at the University of Illinois at Chicago.

    National Nanotechnology Initiative releases new strategic plan

    January 3, 2008

    The new 2007 NNI Strategic Plan for the work of the National Nanotechnology Initiative has been released, describing the vision, goals, and priorities of the NNI, high-impact application opportunities, and critical research needs.

    New optical disc has 100 gigabytes memory

    July 11, 2005

    Sharp Corp. says it has developed a technology to manufacture a new optical disc with 100 gigabytes of memory.

    Probe captures high-resolution images of nanomaterials

    March 30, 2011

    Nano Materials

    Scientists at Berkeley Lab’s Molecular Foundry have pioneered a new chemical mapping method that provides unprecedented insight into materials at the nanoscale, says Alexander Weber-Bargioni, a postdoctoral scholar in the Imaging and Manipulation of Nanostructures Facility at the Foundry.

    The team designed and fabricated a coaxial antenna capable of focusing light at the nanoscale using a state-of-the-art focused ion beam tool. The antenna consists of… read more

    Quantum entanglement stronger than suspected

    July 18, 2002

    Pairs of photons linked by entanglement can pass through gold sheets without the entanglement being destroyed, in an experiment at Leiden University. The finding means quantum linking of particles is far more robust than scientists thought and could help them develop new ways of making quantum computers.

    Plugging In $40 Computers

    May 22, 2009

    SheevaPlug, a tiny plastic “plug computer” that you plug into an electric outlet, includes a 1.2 Ghz application processor running Linux with 512 megabytes of RAM and 512 megabytes of flash storage, and USB and Gigabit Ethernet sockets.

    By adding peripherals and software, it can become a network server, security camera to the Internet, video stream storage device, and serve other functions. Price is $99; it may be available… read more
