A new study on the rotation of the universe’s first light could suggest physicists need new rule-breaking subatomic particles.
For noted theoretical physicist Frank Wilczek, finding aliens is a matter of figuring out what exactly we are looking for. To detect other space civilizations, we need to search for the specific effects they might be having on their worlds, argues the Nobel laureate in a new proposal.
Writing in the Wall Street Journal, Wilczek says that it’s a real challenge to figure out which among the over 4000 exoplanets that we found so far outside of our solar system might host extraterrestrial life. The classic way of listening for space signals is insufficient and inefficient, says the scientist. What might really help are new developments in exoplanetary astronomy that can allow us to get much more precise information about faraway space objects.
In particular, there are two ways we should focus our attention to turn the odds of finding alien life in our favor, argues the physicist.
Formic ventures — taking on huge challenges — from virtual reality technologist to longevity biotechnology investor.
Michael Antonov is the Founder and CEO of The Michael Antonov Foundation (https://antonovfoundation.org/), a charitable organization that supports biotechnology research and various causes that improve well being of people around the world, as well as Formic Ventures (https://formic.vc/index.html), an early stage high tech and biotech investment firm focused on prolonging human healthspan and empowering human creativity.
A type of novel molecular voltage sensor makes it possible to watch nerve cells at work. The principle of the method has been known for some time. However, researchers at the University of Bonn and the University of California in Los Angeles have now succeeded in significantly improving it. It allows the propagation of electrical signals in living nerve cells to be observed with high temporal and spatial resolution. This enables investigations into completely new questions that were previously closed to research. The study has now been published in the journal PNAS.
Elon Musk says the Tesla Roadster will be able to fly a little bit, so perhaps the new Model S yoke will be used so that the driver pulls back on it to fly.
It is the OEC biggest challenge.
Google’s parent, Alphabet, has waded through one controversy after another involving its top researchers and executives in the field over the past 18 months.
Richard Feynman, one of the most respected physicists of the twentieth century, said “What I cannot create, I do not understand.” Not surprisingly, many physicists and mathematicians have observed fundamental biological processes with the aim of precisely identifying the minimum ingredients that could generate them. One such example are the patterns of nature observed by Alan Turing. The brilliant English mathematician demonstrated in 1952 that it was possible to explain how a completely homogeneous tissue could be used to create a complex embryo, and he did so using one of the simplest, most elegant mathematical models ever written. One of the results of such models is that the symmetry shown by a cell or a tissue can break under a set of conditions.
Graphene continues to dazzle us with its strength and its versatility – exciting new applications are being discovered for it all the time, and now scientists have found a way of manipulating the wonder material so that it can better filter impurities out of water.
The two-dimensional material comprised of carbon atoms has been studied as a way of cleaning up water before, but the new method could offer the most promising approach yet. It’s all down to the exploitation of what are known as van der Waals gaps: the tiny spaces that appear between 2D nanomaterials when they’re layered on top of each other.
These nanochannels can be used in a variety of ways, which scientists are now exploring, but the thinness of graphene causes a problem for filtration: liquid has to spend much of its time travelling along the horizontal plane, rather than the vertical one, which would be much quicker.
