The software behind the film "Minority Report" -- where Tom Cruise speeds through video on a large screen using only hand gestures -- is making its way into the real world.
-
Daphne Koller and Andrew Ng share a vision in which anyone, no matter how destitute, can expand their minds and prospects with lessons from the world's top universities.

Knee-deep in muddy water, a 10-year-old child and a woman with braided hair lean over a large sieve, washing earth and rocks, their eyes clenched against the filthy splashing water.

South Korea's Samsung Electronics, the world's top smartphone maker, has sold more than 10 million units of its newest Galaxy S III model since its launch about two months ago, a report said Sunday.

A team of mineral physicists has for the first time confirmed through high-pressure experiments the structure of cold-compressed graphite, a form of carbon that is comparable in hardness to its cousin, diamond, but only requires pressure to synthesize. The researchers believe their findings could open the way for a super hard material that can withstand great force and can be used -- as diamond-based materials are now -- for many electronic and industrial applications.

Tony Robbins' followers burned their feet on hot coals this weekend, but did it need to happen? Find out how to firewalk over 1,000 degrees.

Using recent advances in marine biomechanics, materials science, and tissue engineering, a team of researchers at Harvard University and the California Institute of Technology (Caltech) have turned inanimate silicone and living cardiac muscle cells into a freely swimming "jellyfish."

Light is not only the source of a plant's energy, but also an environmental signal that instructs the growth behavior of plants. As a result, a plant's sensitivity to light is of great interest to scientists and their research on this issue could help improve crop yields down the road. Similarly understanding a plant's temperature sensitivity could also help improve agriculture and feed more people. Two new papers from Carnegie's Zhiyong Wang laboratory identify key aspects of the hormonal responses of plants to changes in light and heat in their environments. Their work is published online July 22 by Nature Cell Biology.

In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites. New research from a team including Carnegie's Doug Rumble and Liping Qin focuses on one particularly old type of meteorite called diogenites. These samples were examined using an array of techniques, including precise analysis of certain elements for important clues to some of the Solar System's earliest chemical processing. Their work is published online July 22 by Nature Geoscience.

Only by viewing a Seurat painting at close range can you appreciate the hidden complexities of pointillism small, distinct dots of pure color applied in patterns to form an image from a distance. Similarly, biologists and geneticists have long sought to analyze profiles of genes at the single cell level but technology limitations have only allowed a view from afar until now.

A new technique will allow plant breeders to introduce valuable crop traits even without access to the full genome sequence of that crop.

(Phys.org) -- Samsung is set to begin manufacturing its "Youm" displays which have been generating pre-launch excitement as ultra-thin AMOLED panels that will be bendable, stretchable, rollable and foldable like a piece of paper. Samsung expects to begin production of its 0.6mm Youm displays this quarter, with a goal of seeing the first products with the technology to market by the end of the year. Oddly, though, the displays to roll out this year in the first batch will not have a flexible substrate. They will have a protective glass layer, which in turn will make them unable to take other forms or shapes, the very bend-it, fold-it feature that draws interest at industry shows.

Cell-silicon hybrid may inform design of replacement hearts

When a 100-pound shipment of lobsters arrived at Bill Sarro's seafood shop and restaurant last month, it contained a surprise — six orange crustaceans that have been said to be a 1-in-10-million oddity.

Researchers have identified several gene mutations responsible for the most common childhood brain tumor, called medulloblastoma, adding evidence to the theory that the diagnosis is a group of genetically distinct cancers with different prognoses.

A novel genomic sequencing method called Smart-Seq can help scientists conduct in-depth analyses of clinically relevant single cells. Smart-Seq has many possible applications, including helping scientists to better understand the complexities of tumor development.

Included in the 2012 International Antiviral Society-USA panel recommendations for human immunodeficiency virus patient care is that all adult patients, regardless of CD4 cell count, should be offered antiretroviral therapy.

Scientists have turned inanimate silicone and living cardiac muscle cells into a freely swimming "jellyfish." The finding serves as a proof of concept for reverse engineering a variety of muscular organs and simple life forms.

When one observes a jellyfish pulsating through the ocean, Greek mythology probably doesn't immediately come to mind. But the animal once was known as the medusa, after the snake-haired mythological creature its tentacles resemble. The mythological Medusa's gaze turned people into stone, and now, thanks to recent advances in bio-inspired engineering, a team of researchers have flipped that fable on its head: turning a solid element -- silicon -- and muscle cells into a freely swimming "jellyfish."

A new technique will allow plant breeders to introduce valuable crop traits even without access to the full genome sequence of that crop. The technique links important agronomic traits in crop plants with active regions of the genome. Instead of requiring knowledge of the crop's complete genome, it identifies only expressed genes.

Ending the global HIV/AIDS pandemic may be possible by implementing a multifaceted global effort that expands testing, treatment, and prevention programs, as well as meets the scientific challenges of developing an HIV vaccine and possibly a cure.
