Is dark energy needed to accelerate the expansion of the universe? (Image: Shutterstock)

Fans of Doctor Who will be very familiar with the stupefied phrase uttered by all new visitors to his Tardis: "It's...bigger...on the inside." As it turns out, this apparently irrational idea may have something to contribute to our understanding of the universe. A team of cosmologists in Finland and Poland propose that the observed acceleration of the expansion of the universe, usually explained by dark energy or modified laws of gravity, may actually be the result of regions of spacetime that are larger on the inside than they appear from the outside. The researchers have dubbed these "Tardis regions."  Read More

The Nobel Prize medal is awarded to honor the highest contributions to the sciences (Photo...

The Nobel Prize in Physiology or Medicine for 2013 was awarded jointly today to James E. Rothman, Randy W. Schekman and Thomas C. Südhof "for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells."  Read More

Designer Elizabeth Bigger's Lüme Collection sees simple black garments get a dose of 21st century tech by virtue of embedded LEDs that can be illuminated in patterns controlled from a smartphone.  Read More

Quantum black hole study finds bridge to another Universe (Image: Shutterstock)

Physicists have long thought that the singularities associated with gravity (like the inside of a black hole) should vanish in a quantum theory of gravity. It now appears that this may indeed be the case. Researchers in Uruguay and Louisiana have just published a description of a quantum black hole using loop quantum gravity in which the predictions of physics-ending singularities vanish, and are replaced by bridges to another universe.  Read More

Toyota's i-Road is on the road to production

Toyota's i-Road three-wheeler concept is set to make it off the drawing board and onto the road. Toyota has announced that a limited production run of the fully enclosed, tilting EV will begin shortly, with initial units being transferred to Toyota's Ha:mo urban transport system trials in Toyota City.  Read More

The tiny eCompass chip provides magnetometer and accelerometer capabilities (Image: STMicr... STMicroelectronics has announced a new MEMS-based module that integrates a three-axis magnetometer, a three-axis accelerometer, A/D converters, and control logic on a 2 mm x 2 mm x 1 mm surface mount chip, reportedly making it the smallest electronic compass available today.  Read More

Cornell professor David Muller and grad student Pinshane Huang show a model of the atomic ...

In 2012, a one-molecule thick layer of silica glass was accidently made in the laboratory of Cornell professor David Muller, allowing the atoms in a glass to be seen individually for the first time. Now, Guinness World Records has identified this ultimately thin glass as a 2014 World Record.  Read More

A Tesla Model S that did not have a battery fire (Photo: Crixxor) A Tesla Model S electric automobile, a model which recently won Consumer Reports' Top Scoring Car award and aced the NHTSA's crash rating system, caught fire yesterday in an incident near Seattle. Tesla's shares fell 6.2 percent on the day as a result of the incident.  Read More

Scanning atomic force microscopes, first introduced into commerce in 1989, are a powerful tool for nanoscale science and engineering. Capable of seeing individual atoms, commercial AFM prices range between US$10K and $1M, depending on the unit's features and capabilities. During the recent LEGO2NANO summer school held at Tsinghua University in Beijing, a group of Chinese and English students succeeded in making a Lego-based AFM in five days at a cost less than $500.  Read More

Undetectable hardware Trojans could subvert cryptographic security (Image: Shutterstock)

Researchers have shown that it is possible to compromise the functioning of a cryptographic chip without changing its physical layout. Based on altering the distribution of dopants in a few components on the chip during fabrication, this method represents a big challenge for cyber-security as it is nearly impossible to detect with any currently practical detection scheme.  Read More
