No Big Bang? Quantum equation predicts universe has no beginning



Big Bang

This is an artist's concept of the metric expansion of space, where space (including hypothetical non-observable portions of the universe) is represented at each time by the circular sections. Note on the left the dramatic expansion (not to scale) occurring in the inflationary epoch, and at the center the expansion acceleration. The scheme is decorated with WMAP images on the left and with the representation of stars at the appropriate level of development. Credit: NASA

Tiny Batteries Could Revolutionize Green Energy

Source National Geographic

Nanotechnology could dramatically improve energy storage for electronics, cars, and buildings.

A small battery made up of a billion nanopores, or microscopic holes capable of producing electric current, is the latest breakthrough in the search for lighter, more potent batteries.

Tiny is big in the quest to build batteries that store more energy for cars, buildings, and personal electronics.

Mirrors could replace air conditioning by beaming heat into space

Researchers have created a mirror that not only reflects 97% of light but also radiates heat into the cold depths of the universe

Can our Memories be erased?

Researchers have used an electrical flow to individuals' brains to eradicate upsetting memories, some piece of a goal-oriented mission to better treat illnesses, for example, mental trauma, psychiatric issue and medication fixation.

How Conscious We Are?

Consciousness is the quality or state of mindfulness, or, of being mindful of an outside item or something inside oneself



Consciousness, Conscious, Awareness

OF the three most principal investigative inquiries regarding the human condition, two have been replied. 


To start with, what is our relationship to whatever is left of the universe? Copernicus addressed that one. We're not at the center. We're a bit in a substantial spot.

Evidence Found Of A Particle That Is Its Own Antiparticle

By Francie Diep


There's a particle that physicists theorize exists that acts simultaneously as both matter and antimatter. Whoa! The particle is called the Majorana fermion, and a team of physicists is announcing today that it's seen some evidence of its existence.

Unbelievable Facts About The Human Eye

By Robyn Wilder


1. Your retinas actually perceive the outside world as upside-down – your brain flips the image for you.



If you want to see the world as your retinas do, try a pair of prism glasses. Just don’t, you know, walk near sheer drops or operate heavy machinery while wearing them.

India's Mangalyaan satellite successfully in orbit around Mars

By Tushna Commissariat


India has become the first nation to successfully put a satellite into orbit around Mars on its first attempt. Launched by the Indian Space Research Organisation (ISRO), the Mangalyaan (or "Mars craft") Mars Orbiter began circling the red planet today. The mission is one of the cheapest interplanetary space missions ever launched, and puts India on a par with the US, Russia and the European Space Agency, which have also sent spacecraft to Mars.

US plans for future of fusion research

By Mark Zastrow

Facilities should support the beleaguered ITER project, a panel recommends.

A fusion-physics advisory panel recommends closure of the Alcator C-Mod experiment at the Massachusetts Institute of Technology.


As the international ITER project to build an experimental nuclear fusion reactor in Cadarache, France, eats into research budgets around the world, an advisory panel to the US Department of Energy recommends mothballing at least one of three major experiments and focusing on the research necessary to bring ITER online.

The Funniest Theories in Physics

Intro

Nobel Prize winner Ernest Rutherford once said, "all science is either physics or stamp collecting." (Ironically, Rutherford won his Nobel in chemistry, not physics). Physicists may not be the most modest people out there, but if there's one thing they are good at, it's coming up with names for their ideas. Here are some of the best-named physics stuff out there, and what it means.

Ig Nobel Prizes 2014: Jesus Toast, Dog Poop and Raucous Science

CAMBRIDGE, Mass. — The brilliant minds behind research studies about how Earth's magnetic field affects pooping dogs and why people see Jesus in toast were honored tonight (Sept. 18) during one of the most purposefully ridiculous ceremonies in all of science: the Ig Nobel Prizes.
Each year, the Ig Nobel Prizes (a parody of the somewhat more famous Nobel Prizes) are awarded to scientists whose research "makes people laugh and then think." Improbable Research, the organization that awards the prizes, runs the annual ceremony here at Harvard University's Sanders Theater.
And what a ceremony it was. Two "human sparkplugs" dressed in little more than silver body paint were welcomed on stage to usher speakers to the microphone, and paper airplanes flew through the theater on more than one occasion. But the food-themed night was truly about honoring science and the scientists who do it.

Engineered proteins stick like glue -- even in water

Researchers have found new adhesives based on mussel proteins could be useful for naval or medical applications. To create their new waterproof adhesives, researchers engineered bacteria to produce a hybrid material that incorporates naturally sticky mussel proteins as well as a bacterial protein found in biofilms -- slimy layers formed by bacteria growing on a surface. When combined, these proteins form even stronger underwater adhesives than those secreted by mussels.

For the first time, scientists have discovered how to produce ultra-thin 'diamond nanothreads' that promise extraordinary properties, including strength and stiffness greater than that of today's strongest nanotubes and polymers. The threads have a structure that has never been seen before.

What You Need To Know About The Solar Storm Headed For Earth

Two solar flares have sent magnetic fields to our planet -- and scientists aren’t sure how they’re going to impact each other.
