SCUBA simulator advances the field of virtual reality while exploring the relationship between diving and disability"My diving bell becomes less oppressive, and my mind takes flight like a butterfly," Jean-Dominique Bauby wrote in his agonizingly beautiful account of living with severe disabilities, The Diving Bell and the Butterfly. Holding these contrasting images of physical submersion and mental liberation in your mind is a useful way to approach Dhruv Jain's virtual reality project, Amphibian. Jain, a master of science candidate in the MIT Media Lab's Living Mobile Group who is partially deaf, creat
- (Phys.org)—A team of researchers from Poland, Spain and Austria has discovered that brown bears living in Poland have glands in their paws that produce chemicals that the bears use to communicate with other bears. In their paper published in Scientific Reports, the team describes their study of multiple bears in the wild and what they observed.
- Mathematics and art are generally viewed as very different disciplines – one devoted to abstract thought, the other to feeling. But sometimes the parallels between the two are uncanny.

- Measuring small fast electron populations hidden in a sea of colder "thermal" electrons in tokamak plasmas is very challenging. Why? The challenge comes from the fast electron signal being overwhelmed by thermal electron signal in most diagnostics. Physicists at the University of California-San Diego, with physicists from Oak Ridge National Lab and from General Atomics, have succeeded in measuring fast electron populations. They achieved this first-of-its-kind result by seeing the effect of the
- When you hear someone laugh behind you, you probably picture them on the phone or with a friend – smiling and experiencing a warm, fuzzy feeling inside. Chances are just the sound of the laughter could make you smile or even laugh along. But imagine that the person laughing is just walking around alone in the street, or sitting behind you at a funeral. Suddenly, it doesn't seem so inviting.

Cassini Spacecraft's Ring Dive Yields Saturn Surprises
The Cassini spacecraft spotted strange atmospheric structures during the first of its 22 dives between the rings and the gas body of Saturn — the planet it has studied up close since 2004. Cassini is in the last few months of its extended mission at ...

- Cornelius Senn, a measurement engineer in the Department of Civil, Environmental and Geomatic Engineering (D-BAUG), and his post-doctoral colleague Silvan Leinss have developed a new reflector for radar measurements. The underlying mechanism, however, has many possible applications and could revolutionise furniture construction, for example.
- Using hollow-core optical fibre as a sensitive gas cell, researchers in Japan have devised a relatively simple and affordable sensor for monitoring biomarkers in human breath at low concentrations. Trace amounts of gases exhaled through the nose and mouth offer clues to respiratory conditions such as asthma, as well as other easy-to-administer health screening opportunities.
Fast, robust algorithm for computing stellarator coil shapes yields designs that are easier to build and maintainA stellarator is a device in which plasma can be confined at temperatures hotter than the core of the sun, using magnetic fields from carefully shaped electromagnetic coils. Scientists modified the mathematical optimization problem used to compute the coil shapes. They increased the space between coils. Increasing the space smooths the coils' sharp bends, while preserving the speed and reliability of the previous method.
- In experiments on transport tissues in plants, researchers from Heidelberg University were able to identify factors of crucial importance for the formation of the plant tissue known as phloem. According to Prof. Dr Thomas Greb of the Centre for Organismal Studies (COS), these factors differ from all previously known factors that trigger the specification of cells. The findings of the Heidelberg researchers substantially expand our understanding of the metabolic processes in plants. Their results
- After more than 16 years of operation, NASA's Earth Observing-1 (EO-1) spacecraft was decommissioned on March 30. The EO-1 satellite was a component of NASA's New Millennium Program to validate new technologies that could reduce costs and improve capabilities for future space missions. Aboard EO-1 was the Advanced Land Imager (ALI) instrument developed by MIT Lincoln Laboratory as an alternative to the land-imaging sensor that was used by the Landsat Earth-observing program.
- For breeders of cassava, a staple food for hundreds of millions in the tropics, producing improved varieties has been getting harder over time. A team at Cornell used genomic analysis of cassava varieties and wild relatives to make a diagnosis: Mutations have corroded the genome, producing many dysfunctional versions of genes and putting at risk a crop crucial to the survival of one-tenth of the world's population.
- A spacecraft that scientists from the University of Oxford played a key role in building, has come closer to the planet of Saturn than ever before.
- Traditionally, it has been very difficult to perform live, in-flight testing of newly developed software for satellites. No one wants to take any risk with an existing, valuable satellite, so it there are only limited opportunities to test new procedures, techniques or systems in orbit.

- Mounting anti-terrorism security procedures and the Transportation Security Administration's (TSA) screening processes have launched numerous debates about the protection of civil liberties and equal treatment of passengers. A new study published in Risk Analysis has successfully quantified how much potential air passengers value equal protection when measured against sacrifices in safety, cost, wait time, and convenience.
- Price peaks of wheat on the world market are mainly caused by production shocks like those induced, for example, by droughts, researchers found. These shocks are exacerbated by low storage levels as well as protective trade policies, the analysis of global data deriving from the U.S. Department of Agriculture shows. In contrast to widespread assumptions, neither speculation across stock or commodity markets nor land use for biofuel production were decisive for annual wheat price changes in the p
- Recent articles have declared that deposits of raw mineral materials (copper, zinc, etc.) will be exhausted within a few decades. An international team including the University of Geneva (UNIGE), Switzerland, has shown that this is incorrect and that the resources of most mineral commodities are sufficient to meet the growing demand from industrialization and future demographic changes. Future shortages will arise not from physical exhaustion of metals but from causes related to industrial explo
- Whether you prefer a cool summer night with a gentle breeze or a crystal clear and still winter day, the human perception of temperature, or thermal comfort, while largely dependent on the temperature itself, involves several other climate variables, such as humidity and wind speed.

- An international project led by VTT Technical Research Centre of Finland has developed a new augmented reality (AR) tool for the ESA. In the future, it is envisaged that astronauts will be able to use this tool to perform maintenance tasks and real-time equipment monitoring in the demanding conditions of space. The first practical tests carried out at ESA's European Astronaut Centre produced excellent results.
