From Technology Review:

The next few years will see at least two new commercial spacecraft put into orbit.

A small fleet of privately developed spacecraft will head into orbit in the next few years--assuming that current levels of public and private funding can be sustained. If it happens, this will mark a new chapter in space exploration and research, as NASA comes to rely more on private companies for the technology to put manned and unmanned vehicles in space.

Global Energy Use In The 21st Century

World energy consumption by type in 2006 - Image: Wikimedia

From Watts Up With That?:

Guest Post by Thomas Fuller

This is a great time to talk about energy use worldwide. Not because it’s topical, or politically important, or anything like that. It’s a great time because the math is easier now than ever before, and easier than it ever will be again.

It’s similar to a time a few years ago when there were almost exactly 100 million households in the United States. It made a lot of calculations really easy to do. And this year, the United States Department of Energy calculates that the world used 500 quads of energy. Ah, the symmetry.

DARPA's Cyber Insider Threat Program Is The Agency's Great Hope For Ending Leaks

Protecting Military Networks Thinking about WikiLeaking? Think again. U.S. Navy

From Popular Science:

The recent WikiLeaks exposure was a huge black eye for the U.S. Department of Defense, supposedly one of the more secure state organizations we have working for us. Its impact clearly wasn’t lost on the Pentagon, whose blue sky research arm has launched a new project designed to ferret out malicious behavior on DoD networks. Named CINDER – Cyber INsiDER Threat – the project is designed not to sniff out people, but adversarial actions as they happen.

Why Older People Repeat Stories

From Live Science:

There may be a reason grandparents repeat the same stories over and over again. According to a new study, older people are more likely than younger people to forget with whom they've shared information.

The study investigated two types of memory: source memory, or your recollection of who told you a piece of information; and destination memory, which is your recollection of which people you've informed. Not only were older people bad at remembering to whom they'd told information, they were very confident in their mistaken memories. [10 Ways to Keep Your Mind Sharp]

From The CBS:

We know it's hot up there but NASA wants to know a bit more about the Sun and its environs. And so sometime before 2018, the agency intends to send a spacecraft into the solar atmosphere.

This will mark the first time that a spacecraft from earth will actually visit a star.

The decision to chart a mission to the Sun also realizes a dream that astronomers almost realized a half century ago, when the National Academy of Science's "Simpson Committee" in 1958 recommended a probe to investigate. Several studies were subsequently carried out testing the feasibility of the project. But nothing came of them.

From Technology Review:

The largest-ever storm monitoring mission is now gathering scientific data that was previously impossible to get.

As Hurricane Earl barrels toward the eastern seaboard of the United States, coastal residents don't know if they should evacuate in case the storm makes landfall. They rely on forecasters analyzing computer models, but those predictions differ. A new hurricane-monitoring mission that's now underway hopes to reduce this uncertainty by gathering atmospheric and environmental storm data never before obtained.

Earliest Fossil Evidence Of Humans In Southeast Asia?

Archaeologists excavating Callao Cave in the Philippines.

From Earth Magazine:

Modern humans reached the islands of Southeast Asia by approximately 50,000 years ago, but our ancestors’ journey was not easy. Even during times of low sea level, a voyage to some of these islands would have required crossing open water, leaving many scientists to wonder how humans arrived on the most isolated islands. Now the story is growing more complicated: A group of archaeologists has discovered a 67,000-year-old foot bone that they say represents the earliest-known presence of humans in the northern Philippines and may be among the oldest-known traces of modern humans in all of Southeast Asia — that is, if the bone truly belongs to Homo sapiens.

The U.S. Sniper's More Accurate, Quieter Rifle -- Popular Mechanics

Army Snipers in Afghanistan will receive an improved rifle this fall.

For snipers, every war is different. Recognizing the differences between conditions in Iraq and Afghanistan, the Army is now selecting a contractor to upgrade the 22-year-old Remington bolt-action rifle to become a more effective killing machine. The Army will pour about $5.6 million into upgrades to the M24, with the new gear expected to be delivered to troops by this fall. The M24's barrel is being modified to shoot heavier .300 Winchester Magnum rounds, instead of the 7.62mm NATO ammunition, which should extend the rifle's maximum effective range by hundreds of yards to a maximum of about 1400 yards. The suppressor will reduce the noise and flash of the gun so snipers can stay in their hiding positions much longer after they fire.

Brain-Like Computing On An Organic Molecular Layer

Magnetic resonance images of human brain during different functions appear on top. Similar evolving patterns have been generated on the molecular monolayer one after another (bottom). A snapshot of the evolving pattern for a particular brain function is captured using Scanning Tunneling Microscope at 0.68 V tip bias (scale bar is 6 nm). The input pattern to mimic particular brain function is distinct, and the dynamics of pattern evolution is also typical for a particular brain operation. (Credit: Anirban Bandyopadhyay)

From Science Daily:

ScienceDaily (Apr. 26, 2010) — Information processing circuits in digital computers are static. In our brains, information processing circuits -- neurons -- evolve continuously to solve complex problems. Now, an international research team from Japan and Michigan Technological University has created a similar process of circuit evolution in an organic molecular layer that can solve complex problems. This is the first time a brain-like "evolutionary circuit" has been realized.

From Live Science:

Chimpanzees may gather in hushed quiet to watch a fellow ape in her dying moments, and chimp mothers in the wild may carry their infants' mummified remains for weeks, according to new research on how humanity's closest living relatives deal with the deaths of those closest to them.

Insights into how chimpanzees respond to the death of one of their own are rare. One such instance came with the final hours of Pansy, a chimp more than 50 years old who lived in a Scottish safari park.

The Search For Genes Leads To Unexpected Places

HUNTER Edward M. Marcotte and colleagues at the University of Texas at Austin have found hundreds of genes involved in human disorders. Ben Sklar for The New York Times

From New York Times:

Edward M. Marcotte is looking for drugs that can kill tumors by stopping blood vessel growth, and he and his colleagues at the University of Texas at Austin recently found some good targets — five human genes that are essential for that growth. Now they’re hunting for drugs that can stop those genes from working. Strangely, though, Dr. Marcotte did not discover the new genes in the human genome, nor in lab mice or even fruit flies. He and his colleagues found the genes in yeast.

Apple Sued By Elan Microelectronics Over Touch-Screen Technology

From Times Online:

The sale of Apple's iPhone and iPad in the US is under threat after the US International Trade Commission initiated a formal investigation into the company for allegedly infringing a patent covering multi-touch technology.

The ITC, which has the power to ban the import and sale of products, said it was responding to a request from the Taiwanese touchscreen maker Elan Microelectronics, which has a patent for technology that detects the simultaneous presence of two or more fingers on a touchscreen or touchpad.
