New System Allows Cloud Customers to Detect Program-Tampering

New System Allows Cloud Customers to Detect Program-Tampering

For small and midsize organizations, the outsourcing of demanding computational tasks to the cloud — huge banks of computers accessible over the Internet — can be much more cost-effective than buying their own hardware. But it also poses a security risk: A malicious hacker could rent space on a cloud server and use it to [...]

Sudden Rise of Global Ecology of Interacting Robots Trade at Speeds Too Fast for Humans

Sudden Rise of Global Ecology of Interacting Robots Trade at Speeds Too Fast for Humans

Recently, the global financial market experienced a series of computer glitches that abruptly brought operations to a halt. One reason for these “flash freezes” may be the sudden emergence of mobs of ultrafast robots, which trade on the global markets and operate at speeds beyond human capability, thus overwhelming the system. The appearance of this [...]

Cyborg Astrobiologist Uses Phone-Cam to Search for Signs of Life

Cyborg Astrobiologist Uses Phone-Cam to Search for Signs of Life

A novel, hybrid part-human, part-machine visual system that uses a simple mobile phone camera has been developed to search for evidence of past or present life in planetary analogue sites on Earth. Patrick McGuire from the Freie Universität, Berlin, will present results from this Cyborg Astrobiologist at the European Planetary Science Congress in London on [...]

Training the Older Brain in 3-D: Video Game Enhances Cognitive Control

Training the Older Brain in 3-D: Video Game Enhances Cognitive Control

Scientists at UC San Francisco are reporting that they have found a way to reverse some of the negative effects of aging on the brain, using a video game designed to improve cognitive control.   The findings, published on Sept. 5 in Nature, show that a specially designed 3-D video game can improve cognitive performance [...]

Neutron Stars in the Computer Cloud

Neutron Stars in the Computer Cloud

Einstein@Home discovers 24 new pulsars in archival data. The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer. Using this computer cloud, an international team lead by scientists from the [...]

Computer Can Read Letters Directly from the Brain

Computer Can Read Letters Directly from the Brain

By analysing MRI images of the brain with an elegant mathematical model, it is possible to reconstruct thoughts more accurately than ever before. In this way, researchers from Radboud University Nijmegen have succeeded in determining which letter a test subject was looking at. The journal Neuroimage has accepted the article, which will be published soon. [...]

New Technology Protects Against Password Theft and Phishing Attacks

New technology launched today by Royal Holloway University, will help protect people from the cyber attack known as “phishing,” believed to have affected 37.3 million of us last year, and from online password theft, which rose by 300% during 2012-13. Phishing involves cyber criminals creating fake websites that look like real ones and luring users [...]

Toxic Nanoparticles Might Be Entering Human Food Supply

Toxic Nanoparticles Might Be Entering Human Food Supply

Over the last few years, the use of nanomaterials for water treatment, food packaging, pesticides, cosmetics and other industries has increased. For example, farmers have used silver nanoparticles as a pesticide because of their capability to suppress the growth of harmful organisms. However, a growing concern is that these particles could pose a potential health [...]

Pulsars Make a GPS for the Cosmos

Pulsars Make a GPS for the Cosmos

CSIRO scientists have written software that could guide spacecraft to Alpha Centauri, show that the planet Nibiru doesn’t exist … and prove that the Earth goes around the Sun.   Dr George Hobbs (CSIRO) and his colleagues study pulsars — small spinning stars that deliver regular ‘blips’ or ‘pulses’ of radio waves and, sometimes, X-rays. [...]

Playing Video Games Can Boost Brain Power

Playing Video Games Can Boost Brain Power

Certain types of video games can help to train the brain to become more agile and improve strategic thinking, according to scientists from Queen Mary University of London and University College London (UCL).   The researchers recruited 72 volunteers and measured their ‘cognitive flexibility’ described as a person’s ability to adapt and switch between tasks, [...]
