A team of researchers at Max Planck Institute for Extraterrestrial Physics, working with a colleague at the University of Texas at Austin and another from Green Bank Observatory in West Virginia, has found evidence of ripe conditions for planet formation in the vicinity of two closely orbiting protostars.

In their paper published in The Astrophysical Journal Letters, the group describes their observations and outline what might be learned from future study of the star system.

The work by the team on this new effort came on the heels of work done by another team that discovered a pair of protostars still in the very early stages of their development—in their first 500,000 years of existence. In this new effort, the researchers have taken a closer look at the two protostars and also the environment in which they exist.

We now know of thousands of planets orbiting other stars. But we know of only planet that hosts life – the Earth.
Most scientists think that life elsewhere in the Universe is likely to exist, but so far there is no evidence that extra-terrestrials exist or that they have visited us. However, we can search for signs of life on distant planets and we are even using radio telescopes to look for messages sent to us by extra-terrestrial civilisations. In this talk Tim will discuss the latest science behind the search for alien life.

Tim is a Professor of Astrophysics and an Associate Director of Jodrell Bank Centre for Astrophysics at The University of Manchester.

Tim’s research concentrates on the study of exploding stars using telescopes around the world and in space, working across the spectrum from radio waves to X-rays.

Tim is passionate about astrophysics and its power to inspire. Well known for his regular contributions to science on TV and radio, he is Jodrell Bank’s host for the hugely popular BBC TV Stargazing Live series and has a monthly space discussion programme on BBC Radio 5 Live.

Researchers have finally succeeded in building a long-sought nanoparticle structure, opening the door to new materials with special properties.

Alex Travesset does not have a sparkling research lab stocked with the most cutting-edge instruments for probing new nanomaterials and measuring their unique properties.

Instead of using traditional laboratory instruments, Alex Travesset, a professor of physics and astronomy at Iowa State University and an affiliate of the U.S. Department of Energy’s Ames National Laboratory, relies on computer models, equations, and figures to understand the behavior of new nanomaterials.

Nearly 70 years after having his security clearance revoked by the Atomic Energy Commission (AEC) due to suspicion of being a Soviet spy, Manhattan Project physicist J. Robert Oppenheimer has finally received some form of justice just in time for Christmas, according to a December 16 article in the New York Times. US Secretary of Energy Jennifer M. Granholm released a statement nullifying the controversial decision that badly tarnished the late physicist’s reputation, declaring it to be the result of a “flawed process” that violated the AEC’s own regulations.

Science historian Alex Wellerstein of Stevens Institute of Technology told the New York Times that the exoneration was long overdue. “I’m sure it doesn’t go as far as Oppenheimer and his family would have wanted,” he said. “But it goes pretty far. The injustice done to Oppenheimer doesn’t get undone by this. But it’s nice to see some response and reconciliation even if it’s decades too late.”

Theoretical physicists from Warsaw and Oxford universities argue that a superluminal world possessing three temporal dimensions and one dimension in space could potentially change our concept of time, according to a new paper.

The researchers involved say they have developed “an extension of special relativity” that incorporates three individual time dimensions with a single space dimension, which helps explain how observations made by “superluminal” observers—inertial observers moving faster than the speed of light—might appear.

Within such a framework, the researchers argue that spontaneous events that can occur in the absence of a deterministic cause and other strange phenomena would be experienced by observers moving faster than the speed of light within a vacuum, concepts that potentially transform our concept of time as we know it.

Our earlier paper with the translucent materials:

Separable Subsurface Scattering – Computer Graphics Forum 2015 (presented at EGSR 2015) – J. Jimenez, K. Zsolnai, A. Jarabo, C. Freude, T. Auzinger, X-C. Wu, J. von der Pahlen, M. Wimmer and D. Gutierrez

If you wish to read my latest paper on simulations that look almost like reality, it is available for free here:

Most theories touch on how there are many different worlds, universes, dimensions, or whatever you would like to call them. Each one the same as our own, but also different in some way. For instance, in another world, you might be living the same life as you are now but perhaps politics had gone in a different direction. Maybe all of the presidents that were elected here in the US were opposite from how they are in our world. Maybe everything is the same except for you have different colored hair? The differences between worlds could be minuscule or extreme, it all varies.

While throughout the years many physicists and researchers, in general, have been trying hard to prove the existence of this kind of thing, it has proven to be quite the task. That being said, the concept itself has not been disproven. Now, what this article is about is a concept many do not realize is quite prevalent in these theories. We are all connected to these other worlds or universes. Each one might be separate from our own, but it has been suggested time and time again that when we experience things like déjà vu or peculiar dreams, we are getting a glimpse into one of these other worlds.

This meaning that when someone in another world is dreaming, they could be catching a glimpse into your world as well. Really think about it, if you have some kind of counterpart in another world, and he or she is dreaming they would be seeing perceptions of the lives you and all the others are living. Isn’t that mind-blowing and slightly terrifying? I guess in this sense, dreams are more or less portals.

No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

It’s a monumental head-scratcher known as the ‘grandfather paradox’, but a few years ago physics student Germain Tobar, from the University of Queensland in Australia, worked out how to “square the numbers” to make time travel viable without the paradoxes.
