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 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
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.

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
Nothing keeps the mosquitoes away quite as well as DEET, but it's not the most innocuous of substances – besides stinking, it also melts plastic and synthetic fabrics, plus it's even been linked to problems in users' central nervous systems. It can also be prohibitively expensive for use in developing nations. Thanks to research being conducted at the University of California, Riverside, however, a new generation of non-toxic but highly-effective repellants may be on its way. 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.

A team from the Hong Kong Polytechnic University is to release details of a seven-year program to monitor a 36-km stretch of high-speed rail line using a series of special fiber optic sensors . According to a press release put out by the Optical Society, the system has detected "anomalous vibrations" on 30 occasions, allowing the early rectification of emerging problems that could conceivably have gone on to cause rail accidents.

We've seen a number of innovations that allow for gardening in small spaces, including a ferris wheel-like contraption, a mat that shows you where to plant specially-prepared seeds, and a system that lets you grow vertically-stacked veggies in your window. The TomTato, however, is in a league of its own – it's a single plant that produces both tomatoes and potatoes at the same time. Read More
In a development that would seem to bring a whole new meaning to the term Lightning charger, Nokia and the University of Southampton claim to have used simulated lightning to charge a Nokia Lumia 925 mobile phone. A University press release states that a 200,000 V was "sent" across a 30 cm gap with the light and heat generated supposedly similar to that of a lightning strike. But is there really any cause for excitement, or are we merely witnessing special effects? Read More
Forget using tape recorders and smartphones to play back spoken messages – what if you could simply hear them through a finger? Disney researcher Ivan Poupyrev has come up with a system that allows for just that. Using the human body as a sound transmitter, the technology lets you hear audio messages when someone touches your ear with their finger. Even more strikingly, it also lets you hear those spoken messages off the surface of any ordinary object you might touch, like a knife or a ring. Read More
