Now You Can Feel Wind and Temperature While in Virtual Reality

Realistic visuals and audio are essential to shaping an immersive virtual reality (VR) experience. But these researchers from the National University of Singapore believe VR shouldn’t just cater to sight and sound. For the ultimate VR experience, other senses should come into play as well.

Last year, Nimesha Ranasinghe and his team demonstrated how electrodes can be used to add a sense of taste to VR. Their latest accessory, Ambiotherm, adds another element of realism to the experience: atmosphere.

Latest thinking about terraforming Mars, introducing cyanobacteria

3 Terraforming Mars 1

Terraforming Mars

While scientists believe that at one time, long ago, Mars had an atmosphere similar to Earth’s and was covered with flowing water, the reality today is quite different. In fact, the surface of Mars is so hostile that a vacation in Antarctica would seem pleasant by comparison.

In addition to the extreme cold, there is little atmosphere to speak of and virtually no oxygen. However, a team of students from Germany wants to change that. Their plan is to introduce cyanobacteria into the atmosphere which would convert the ample supplies of CO² into oxygen gas, thus paving the way for possible settlements.

The world is running out of helium

Helium is a very low-density gas.

Jimi Hendrix once said, “I have this one little saying, when things get too heavy just call me helium, the lightest known gas to man.” He was almost right. We know of helium, conventionally, as the lighter-than-air gas that we fill balloons, blimps and zeppelins with in order to quickly and easily “defy gravity” here on Earth. (Video)

Next ice age unlikely to begin for at least 1,500 years

iceage

Concentrations of carbon dioxide emissions, blamed for global warming, will linger in the atmosphere for decades even if the world stopped pumping out emissions today.

The atmosphere contains high levels of carbon dioxide emissions which means the next ice age is unlikely to begin for at least 1,500 years, an article in the journal Nature Geoscience said on Monday.

Is it too late to turn the tides on rising sea levels?

If sea levels rose to where they were during the Last Interglacial Period, large parts of the Gulf of Mexico would be under water (red areas),

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found. The results further suggest that ocean levels continue to rise long after warming of the atmosphere has leveled off.
