Big bang pushed back two billion years

August 7, 2006

Our universe may be 15% larger and older than we thought, according to new measurements of the distance to a nearby galaxy.

Big Bang or Big Chill? The ‘Quantum Graphity’ theory

Is this the hidden granular structure from lensing-like effects? (Credit: James Q. Quach et al./

The start of the Universe should be modeled not as a Big Bang but more like water freezing into ice, according to a team of theoretical physicists at the University of Melbourne and RMIT University.

They suggest that by investigating the cracks and crevices common to all crystals — including ice — our understanding of the nature of the Universe could be revolutionized.

Big Bang glow hints at funnel-shaped Universe

April 16, 2004

Could the Universe be shaped like a medieval horn? It may sound like a surrealist’s dream, but according to Frank Steiner at the University of Ulm in Germany, recent observations hint that the cosmos is stretched out into a long funnel, with a narrow tube at one end flaring out into a bell.

It would also mean that space is finite. If you could fly towards the flared end… read more

Big Bang Chronology Bolstered by Beryllium

August 23, 2004

Astronomers have proof that the very first stars were formed when the universe was less than 200 million years old. Their evidence? Minuscule amounts of beryllium atoms in the outer layers of two faint stars 7200 light-years from Earth.

Big Bang Abandoned in New Model of the Universe

July 29, 2010

A new cosmology successfully explains the accelerating expansion of the universe without dark energy; but only if the universe has no beginning and no end.

Wun-Yi Shu at the National Tsing Hua University in Taiwan has developed an innovative new description of the Universe in which time and space are not independent entities but can be converted back and forth between each other.

In his formulation of the… read more

Big Asteroid Less Likely to Hit Earth

October 8, 2009

The probability of an Earth encounter on April 13, 2036 for the Apophis asteroid has dropped from one-in-45,000 to about four-in-a million, new data from observations made with the University of Hawaii’s 88-inch telescope suggest.

Bidirectional brain signals sense and move virtual objects

October 6, 2011
Monkeys moved and felt virtual objects using only their brain

Two monkeys trained at the Duke University Center for Neuroengineering have learned to employ brain activity alone to move an avatar hand and identify the texture of virtual objects.

“Someday in the near future, quadriplegic patients will take advantage of this technology not only to move their arms and hands and to walk again, but also to sense the texture of objects placed in their… read more

‘Bi-Fi’ — the biological Internet

September 28, 2012

bio_internet_stanford

Using the innocuous M13 bacterial virus, bioengineers at Stanford have created a biological mechanism to send genetic messages from cell to cell — which they term the “biological Internet,” or “Bi-Fi.”

The system greatly increases the complexity and amount of data that can be communicated between cells and could lead to greater control of biological functions within cell communities.

The advance could prove a boon to bioengineers looking… read more

BI and Analytics: A Power Couple

September 19, 2007

The marriage of business intelligence and text analytics is starting to have a profound impact on companies in several industries, including health care, insurance and finance.

Text analytics tools use linguistics, rules-based natural-language processing, specialized algorithms and other methods to impose order on unstructured text scattered throughout the enterprise. More IT executives are using text analytics software to mine disparate document-management applications, e-mail and phone systems, or even blogs… read more

Bezos brings space race to Kent as he plans a passenger rocket

December 26, 2005

Amazon.com billionaire Jeff Bezos is building a rocket-ship complex set to open early next year.

Blue Origin, Bezos’ aerospace company, plans to develop a vehicle that can take passengers on a thrill ride to the edge of space. But eventually, Bezos has said, he wants to build spaceships powerful enough to orbit the Earth. He even hopes to establish permanent colonies in space someday.

Beyond Wi-Fi: The 5 next big things

April 16, 2003

Ultrawideband, mesh networks, software-defined radio, wireless personal area networks, and adaptive radio are the next big things beyond WiFi networks, bringing broader geographical coverage and better use of spectrum.

Beyond Voice Recognition, to a Computer That Reads Lips

September 11, 2003

Scientists at IBM, Intel, and in many other labs are developing digital lip-reading systems to augment the accuracy of speech recognition.

Beyond the touchscreen: Projecting the future

August 3, 2010

Merged 3D imagery and multitouch screens, “furscreens” you can stroke, and Pixar-inspired “lamps” that could add another dimension to table-top displays were among the innovations at the recent SIGGRAPH computer graphics and animation conference.

Beyond the petaflop: DARPA wants quintillion-speed computers

June 24, 2010

DARPA this week announced a program aimed at building “extreme scale computing” machines that achieve one quintillion (1,000,000,000,000,000,000) calculations per second.

Beyond the looking glass…

August 14, 2009

A “hidden portal” invisibility cloak may be possible using exotic new single-crystal yttrium-iron-garnet ferrite metamaterials that force light and other forms of electromagnetic radiation in complicated directions, researchers from the Hong Kong University of Science and Technology and Fudan University have found.

People standing outside the portal would see something like a mirror.
