If all goes to plan, the LHC will come back to life in November. Sam Wong explains the measures being taken to prevent another catastrophic failure, and gauges the mood of physicists at Cern. Can they bag the Higgs before the Americans?

It's been nearly a year since the world's biggest science experiment, the Large Hadron Collider (LHC), was fired up for the first time in a flurry of excitement at Cern, the European Centre for Nuclear Research in Switzerland. But ever since a catastrophic explosion in the particle accelerator's tunnel just nine days after startup, the gargantuan machine has sat idling, to the acute frustration and no little embarrassment of all involved.

New Sub "War" Range May Harm Rare Whales, Critics Say

A right whale mother and calf swim off Florida. Approved in August 2009, a planned U.S. submarine war-games zone has conservationists concerned for the survival of the North Atlantic right whale. The species numbers 300 to 350, and its only known calving ground is near the soon-to-be-built testing range. Photograph courtesy National Oceanic Atmospheric Association/AP

From National Geographic:

After considering several candidates, the U.S. Navy announced last week that it will build its latest submarine warfare training facility in the waters off Jacksonville, Florida. (See map.)

But even though the site won't open until 2014, the new tenant is already having trouble with its neighbors.

That's because the chosen site for the Undersea Warfare Training Range is just 30 miles (48 kilometers) from the only known calving grounds of the North Atlantic right whale.

My Comment: I am sure that every other maritime power in the world .... from China to India, Russia to Venezuela .... are just as (cough cough) equally concerned about the whales.

From my point of view I say forget about these maritime powers, we should focus on the native peoples of America who kill scores of whales each year off the Alaskan and Canadian coasts for "traditional reasons".

But all I hear is silence.

From CNET:

The X-51A WaveRider is one step closer to its inaugural test flight later this year, now that airmen at Edwards Air Force Base have successfully "mated" the scramjet-propelled vehicle to a B-52 Stratofortress.

In December, an Air Force Flight Test Center B-52 is scheduled to papoose the X-51A to 50,000 feet over the Pacific Ocean before cutting it loose. At that point, a solid rocket booster from an ATACMS missile will fire up, accelerating the X-51 to about Mach 4.5. That's when the supersonic combustion ramjet kicks in, pushing the WaveRider to more than Mach 6 for up to five minutes, longer than all of its predecessors combined. NASA tests have reached Mach 9.6, or nearly 7,000 mph, according to some reports, but not for very long. The previous record was less than 10 seconds. Flight data will be telemetered back to Edwards Force Base before the X-51A test vehicle crashes into the Pacific.

Second Backwards Planet Found, A Day After The First

The planet HAT-P-7b, which is about 1.4 times as wide as Jupiter and 1.8 times as massive, seems to orbit its star in the opposite direction to the star's spin (Illustration: Leiden Observatory)

From New Scientist:

Just a day after the announcement of the first extrasolar planet found orbiting its star backwards, two other teams announced the discovery of a second one.

"It is funny that the two good cases for really misaligned orbits, even retrograde orbits, have come at around the same time," says Joshua Winn of MIT, lead author of one of the new papers.

Both Winn's team and another, led by Norio Narita at the National Astronomical Observatory of Japan, used the Japanese Subaru telescope to observe planet HAT-P-7b, a previously known planet about 1000 light years from Earth that was recently observed by NASA's new planet-hunting satellite Kepler.

Both teams found that the planet's orbit is wildly tilted with respect to its star's equator.

Fire Used to Make Better Tools 75,000 Years Ago

From :Live Science

Early humans crossed a threshold around 75,000 years ago, when they started painting symbols, carving patterns and making jewelry. A new study found they also began to use fire to make tools around that time.

Until now, this complex, multi-step process for tool making was only known to occur as recently as 25,000 years ago in Europe. But the new findings show this breakthrough occurred much earlier, and in Africa, not Europe.
By heating up stones in a fire before chipping away at them to make blades, early humans could make tools sharper and produce them more efficiently.
Scientists think this advancement represents a link between the earlier use of fire for cooking and warmth, and the later production of ceramics and metals

From Science Daily:

ScienceDaily (Aug. 13, 2009) — Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically – but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science.

These circuits act like artificial atoms in that they can only gain or lose energy in packets, or quanta, by jumping between discrete energy levels. "In our previous work, we focused on systems with just two energy levels, 'qubits,' because they are the quantum analog of 'bits,' which have two states, on and off," said Matthew Neeley, first author and a graduate student at UCSB.

Another Nutritional Challenge For Space Food

From L.A. Times:

You may have read yesterday’s story about the food scientists at NASA who have their hands full trying to figure out what astronauts will eat when they blast off on a three-year mission to Mars sometime after the year 2030. For a variety of reasons, the food served on the space shuttle and International Space Station won’t cut it – it’s too heavy, too bulky, and its chemistry makes it prone to spoilage after only a couple of years.

And now the NASA scientists have identified another problem: many of the essential vitamins, amino acids and fatty acids in the foods will degrade over the course of such a long mission.

From The Guardian:

Ice and glacier coverage at lower altitudes in cold climates more important than collision of tectonic plates, researchers find.

Scientists have solved the mystery of why the world's highest mountains sit near the equator - colder climates are better at eroding peaks than had previously been realised.

Mountains are built by the collisions between continental plates that force land upwards. The fastest mountain growth is around 10mm a year in places such as New Zealand and parts of the Himalayas, but more commonly peaks grow at around 2-3mm per year.

From Christian Science Monitor:

A panel moves closer to recommending where NASA should fly next, and how.

If the US simply maintains spending for human spaceflight at current levels, NASA will have enough money to build one new rocket to carry crews into space by 2020. But it will literally be a rocket to nowhere: The space agency will have no place to send it for at least another decade.

That stark message underlies options for the US human spaceflight program, which a 10-member panel will present to the Obama administration when it wraps up its work at the end of August. The panel's assignment: Present the president with choices that are sustainable, fit within current budget constraints, yet represent bold steps beyond low-Earth orbit.

Antibodies To Strep Throat Bacteria Linked To Obsessive Compulsive Disorder In Mice

from :ScienceDaily

A new study by researchers at Columbia University Mailman School of Public Health's Center for Infection and Immunity indicates that pediatric obsessive-compulsive disorder (OCD), Tourette syndrome and/or tic disorder may develop from an inappropriate immune response to the bacteria causing common throat infections.





The mouse model findings, published online by Nature Publishing Group in this week's Molecular Psychiatry, support the view that this condition is a distinct disorder, and represent a key advance in tracing the path leading from an ordinary infection in childhood to the surfacing of a psychiatric syndrome. The research provides new insights into identifying children at risk for autoimmune brain disorders and suggests potential avenues for treatment.
OCD and tic disorders affect a significant portion of the population. More than 25% of adults and over 3% of children manifest some features of these disorders. Until now, scientists have been unable to convincingly document the association between the appearance of antibodies directed against Group A beta-hemolytic streptoccoccus (GABHS) in peripheral blood and the onset of the behavioral and motor aspects of the disorder. As a result, treatment strategies were restricted to targeting symptoms rather than causes.

From New Scientist:

A brain region critical to speech and language ballooned after humans split from chimpanzees, a new study finds.

Named after French physician, Pierre Paul Broca, who identified the region in two brain-damaged patients incapable of uttering more than a few words, Broca's area usually occupies a much larger portion of the left half of the human brain than the right.

Because right-handed humans also tend to process language in their left halves – lefties' brain are flip-flopped – some researchers think that lop-sidedness in Broca's area may help explain why humans alone developed language.

From Live Science:

The look of amazement in the eyes of an infant suggests the wheels are churning away inside that noggin. New research confirms they are. Scientists have shown that when 9-month-olds watch people reach for objects, the motor region in their brains gets activated, as if the babies were doing the reaching themselves.

The brain ability is likely due to so-called mirror neurons, which fire both when we do an action ourselves, and when we watch others do a similar action. While such neurons have only been directly measured in monkeys, scientists think they exist in adult humans, and now in infants.
