Graphene disipating heat

'Researchers at Chalmers University of Technology have developed a method for cooling electronics using graphene-based film.

 

The researchers have shown that the in-plane thermal conductivity of the graphene-based film, with 20 micrometre thickness, can reach a thermal conductivity value of 1600W/mK, which is four times that of copper.

"Increased thermal capacity could lead to several new applications for graphene," said Liu. "One example is the integration of graphene-based film into microelectronic devices and systems, such as highly efficient Light Emitting Diodes (LEDs), lasers and radio frequency components for cooling purposes. Graphene-based film could also pave the way for faster, smaller, more energy efficient, sustainable high power electronics."'

Fwd: Mars

'NASA has already begun trying to figure out where its first Mars astronauts should touch down, about two decades before the pioneers are scheduled to launch toward the Red Planet.

Trace looks at the top theories for how Mars could be terraformed. Just don't expect for there to be a nice new red planet to move to before the next Super Bowl.

The space agency will hold a workshop in Houston this October to kick off serious discussions about possible landing sites for NASA's first manned Mars mission, which the agency aims to launch by the mid- to late 2030s.

At the four-day meeting, researchers will propose roughly 62-mile-wide (100 kilometers) "exploration zones" that they believe would be scientifically interesting and possess enough resources, such as subsurface water ice, to support human explorers.'

The first 20 hours -- how to learn anything

My comment on Facebook about evolution.

I'm sorry that you feel that evolution is a religion. In my opinion, evolution says nothing about the existence or non-existence of God. There are two facts that are irrefutable: The earth is very old and simpler organisms came before more complex ones. If you want to say that God made things happen that way, I'm fine with that. That would be philosophy. Science only deals with what we can observe, predict and reproduce. Evolution is the best explanation for what we observe. It is also supported by evidence from several sciences.

Darwin did not invent evolution. Many people of scientific bent believed in and proposed evolution before Darwin. i.e. Lamark in 1800 and Darwin's grandfather. Darwin's great contribution to science was Natural Selection. He wasn't the first to come up with that either. So did the ancient Greeks.

Fwd: NRAM

'A new low-power, high-speed memory technology on the horizon could replace solid-state drives, hard drives and DRAM in PCs, and bring higher levels of storage capacity to mobile devices and wearables.

The new memory from Nantero, called NRAM (nonvolatile RAM), is based on carbon nanotubes. The memory is hundreds of times faster than flash storage used in mobile devices and SSDs, claimed Greg Schmergel, CEO of the company.

Carbon nanotubes are cylinders made out of carbon atoms, with a diameter of one to two nanometers. The nanotubes are known to be stronger than steel, and better conductors of electricity than other known materials used in chips, making the technology an excellent candidate for storage and memory.

Nantero's NRAM operates at the speed of DRAM and is nonvolatile, meaning it can store data. The small size of carbon nanotubes allows more data to be crammed into tighter spaces, and the storage chips will consume significantly less power than flash storage and DRAM. That could bring more storage and longer battery life to laptops and mobile devices…

Nantero, which was formed in 2001, has spent 14 years refining carbon nanotubes, which has been researched for decades by universities, the U.S. government and companies like IBM and Intel. Many top chip and device makers have shown interest in NRAM, which is now ready for manufacturing, Schmergel said…

Nantero won't make the NRAM, but license the technology to device makers and manufacturers. The first NRAM chips will appear as DRAM-compatible modules that can be plugged directly into memory slots on motherboards.

"We are designing chips that are DDR3 and DDR4 compatible, you just put in carbon-nanotube memory," Schmergel said.

Devices makers will be able to put carbon-nanotube storage on top of NAND flash circuitry so it fits in mobile devices and PCs. The technology will be compatible with storage, memory systems and protocols that exist today, Schmergel said.

The NRAM chips should arrive in the next few years, Schmergel said, adding that chip and device makers are designing the memory into new products. '

Fwd: Camera

'' When a crystal lattice is excited by a laser pulse, waves of jostling atoms can travel through the material at close to one sixth the speed of light, or approximately 28,000 miles/second. Scientists now have a new tool to take movies of such superfast movement in a single shot.

Researchers from Japan have developed a new high-speed camera that can record events at a rate of more than 1-trillion-frames-per-second. That speed is more than one thousand times faster than conventional high-speed cameras. Called STAMP, for Sequentially Timed All-optical Mapping Photography, the new camera technology "holds great promise for studying a diverse range of previously unexplored complex ultrafast phenomena," said Keiichi Nakagawa, a research fellow at the University of Tokyo, who worked to develop the camera with colleagues from an array of Japanese research institutions.

Conventional high-speed cameras are limited by the processing speed of their mechanical and electrical components. STAMP overcomes these limitations by using only fast, optical components.

Fwd: Food

'Being dangerously overweight is all down to bad diet rather than a lack of exercise, according to a trio of doctors who have reopened the debate about whether food, sedentary lifestyles or both are responsible for the obesity epidemic.

In an article for a leading health journal the authors – who include British cardiologist Dr Aseem Malhotra, an outspoken critic of the food industry – accuse food and drink firms such as Coca-Cola of having wrongly emphasised how physical activity and sport can help prevent people becoming very overweight.

The truth, they say, is that while physical activity is useful in reducing the risk of developing heart disease, dementia and other conditions, it "does not promote weight loss".

"In the past 30 years, as obesity has rocketed, there has been little change in physical activity levels in the western population. This places the blame for our expanding waistlines directly on the type and amount of calories consumed."

The authors add: "Members of the public are drowned by an unhelpful message about maintaining a 'healthy weight' through calorie counting, and many still wrongly believe that obesity is entirely due to lack of exercise." '

Complex organic molecules such as formamide, from which sugars, amino acids and even nucleic acids essential for life can be made, already appear in the regions where stars similar to our Sun are born.

Fwd: Baby Galaxies

'Astronomers stunned to discover massive clusters of baby galaxies in distant universe

Scientists have discovered the precursors to huge clusters of galaxies that are seen today, and it's all thanks to the European Space Agency's Herschel and Planck space observatories.

Astronomers have combined observations of the distant universe made by the Herschel and Planck space observatories to discover what led about to the huge galaxy clusters we see today, according to a Space Daily

Galaxies are rarely found floating on their own, and instead are usually found in large clusters of galaxies of tens or even hundreds. However, clusters like this haven't always existed, and the question has always plagued scientists: how and when did they form?

With these new insights, scientists should now be able to form better theories and gain new insight into how galaxy clusters evolved, including how dark matter influences these formations.

Astronomers used the Herschel and Planck observatories to peer deep into space and into the distant universe, examining what the universe looked like at 3 billion years old. Brenda Frye, an assistant astronomer at the University of Arizona's Steward Observatory who participated in conducting the research, said that scientists had discovered a cluster of galaxies that might be what a baby cluster would look like, according to the report.'
