Rumor has it that the first dark matter particle has been found!

December 8th, 2009

Dark Matter

The physics blogs are abuzz with rumours that a particle of dark matter has finally been found.

If it is true, it is huge news. Dark matter is thought to make up 90 per cent of the universe’s mass and what evidence there is for it remains highly controversial. That’s why any news of a sighting is seized upon.
The Cryogenic Dark Matter Search experiment is one of several designed to look for the tell-tale signature of dark matter particles passing through. No one is sure what a dark matter particle will look like, though theory gives some pointers.
Most of the experiments have been designed to look for elusive massive particles called WIMPS that barely register as they pass through matter, because the only forces they experience are gravity and the weak nuclear force.
CDMS is located deep underground in the Soudan mine in Minnesota, to protect it from the hail of cosmic rays that would otherwise wash out any dark matter signal.
Earlier this year, the collaboration published a paper in Physical Review Letters (vol 102, p011301) based on two series of experiments between October 2006 and July 2007. They found nothing.
So researchers have been waiting eagerly for the next chapter of the story – maybe with more time, more experience running their detector and a sprinkling of luck, the team would spot a dark matter particle.
The gossip mill went into overdrive after a rumour leaked out that the CDMS collaboration has had a paper accepted by the journal Nature. Word is that the paper will appear in the 18 December issue.
Nature is an unusual place for particle physicists to publish their papers and this has prompted speculation that the news must be big.
A few physicists I know say that talks have hurriedly been scheduled for 18 December at SLAC National Laboratory, the University of California Santa Barbara and Fermilab – all prominent institutions within the CDMS collaboration.
We’ll have to wait and see if the rumours turn out to be true. Even if not, with NASA’s Fermi satellite looking for dark matter in space and the Large Hadron Collider up and running, 2010 could be the year we finally crack the dark matter mystery.

Some black holes may actually be ‘quark stars’

December 7th, 2009

black hole, quark star

Think black holes are strange? Understandable, considering these powerhouses of the universe (many times heavier than our sun) are collapsed stars with gravity so strong that even light cannot escape their grasp.

But maybe they’re not “strange” enough, some astrophysicists suggest. “Stellar” black holes, ones only a few times heavier than the sun, may actually be something even weirder called a quark star, or “strange” star.

A physics team led by Zoltan Kovacs of the University of Hong Kong sizes up the issue in the current Monthly Notices of the Royal Astronomical Society. Quark stars are only theoretical right now, but “the observational identification of quarks stars would represent a major scientific achievement,” Kovacs says.

If quark stars exist, it could prove a theory that normal matter – the stuff of people, planets and stars – isn’t stable and could help explain the existence of the “dark matter” that fills much of the universe.

First suggested in 1970, a strange star is a collapsed star that doesn’t quite crumple enough to turn into a full-fledged black hole and yet is too heavy to become a so-called neutron star (at least 1.4 times heavier than the sun.) Neutron stars do exist, as astronomer Jocelyn Bell showed with the discovery of a pulsar, a spinning neutron star that streams particles from its poles.

In a quark star, gravity would be so strong that it squeezes the subatomic particles called quarks right out of the protons and neutron building blocks of the original star’s atoms. That would leave behind a solid mass of quark stuff called strange matter, hence the name “strange star.”

Earlier in the decade, astronomers suggested that a neutron star called RX J1856, about 400 light-years away (one light-year is about 5.9 trillion miles) was about one-third too small and might be a quark star. But a 2004 Nuclear Physics B journal report showed the star’s intense magnetic field explained its size, so it really was a neutron star.

So, if size alone won’t reveal a quark star, what will? In the new study, Kovacs and his colleagues, Cheng Kwong-sang and Tiberiu Harko, analyze the disks of dust and gas circling supposed black holes. Whipped to high speeds by the intense gravity of a black hole, these disks are thought to heat to high temperatures and emit powerful radiation. For a quark star, the radiation would be about 10% less than predicted around a black hole, they find. And a quark star would give off a dim light (called bremsstrahlung emission), unlike a black hole, emitted by a thin layer of electrons on its surface.

EPA: Greenhouse gases are harmful to humans

December 7th, 2009

EPA: Greenhouse gases are harmful!

WASHINGTON – The Environmental Protection Agency took a major step Monday toward regulating greenhouses gases, concluding that climate changing pollution threatens the public health and the environment.

The announcement came as the Obama administration looked to boost its arguments at an international climate conference that the United States is aggressively taking actions to combat global warming, even though Congress has yet to act on climate legislation. The conference opened Monday in Copenhagen.

The EPA said that the scientific evidence surrounding climate change clearly shows that greenhouse gases “threaten the public health and welfare of the American people” and that the pollutants — mainly carbon dioxide from burning fossil fuels — should be regulated under the Clean Air Act.

“These long-overdue findings cement 2009’s place in history as the year when the United States government began addressing the challenge of greenhouse-gas pollution,” said EPA Administrator Lisa Jackson at news conference.

The action by the EPA, which has been anticipated for months, clearly was timed to add to the momentum toward some sort of agreement on climate change at the Copenhagen conference and try to push Congress to approve climate legislation.

“This is a clear message to Copenhagen of the Obama administration’s commitments to address global climate change,” said Sen. John Kerry, D-Mass., lead author of a climate bill before the Senate. “The message to Congress is crystal clear: get moving.”

Obama planned to talk with former Vice President Al Gore at the White House on Monday as the president prepares for his appearance on Dec. 18 at the climate summit in Copenhagen. Gore won the Nobel Peace Prize in 2007 for his work toward combating climate change.

Obama is also meeting on Wednesday with environmental leaders and U.S. business leaders to discuss climate change.

Under a Supreme Court ruling, the finding of endangerment is needed before the EPA can regulate carbon dioxide and five other greenhouse gases released from power plants, factories and automobiles under the federal Clean Air Act.

The EPA signaled last April that it was inclined to view heat-trapping pollution as a threat to public health and welfare and began to take public comments under a formal rulemaking. The action marked a reversal from the Bush administration, which had declined to aggressively pursue the issue.

Business groups have strongly argued against tackling global warming through the Clean Air Act, saying it is less flexible and more costly than the cap-and-trade bill being considered before Congress. On Monday, some of those groups questioned the timing of the EPA’s announcement, calling it political.

“The implications of today’s action by EPA are far-reaching … individual Americans and consumers and businesses alike will be dramatically affected by this decision,” said Charles T. Drevna, the president of the National Petrochemical & Refiners Association. Drevna, in a statement, said “it is hardly the time to risk the remainder of the U.S. industrial sector in an attempt to achieve a short-term international public relations victory.”

Fossilized Life Found Is Believed To Be From Planet Mars!

Fossilized Life Found On Mars

Bacteria from Mars found inside ancient meteorite

Martian bacteria arrived on Earth on a meteorite which smashed into the Antarctic 13,000 years ago, Nasa scientists believe.

Their fossilised remains have been found in the rock, which was blasted out of Mars 16 million years ago as the solar system was forming.  The meteorite, called Allen Hills 84001, made headlines in 1996 after fossils were found in it. Scientists believed they were bacteria from Earth that contaminated the rock while it lay in the frozen wastes.  But a Nasa report now says there is strong evidence they originated on Mars, according to The Sun.

Dr Emily Baldwin, deputy editor of the UK’s Astronomy Now magazine, said: “Many scientists argued that what looked like fossils in the meteorite were really caused by the explosive event, such as an asteroid impact, that blasted the rock out of Mars in the first place.  “But the Nasa team is now saying they have proved that they could not have been produced by the blast itself.
“If the features turn out to have an extraterrestrial, biological origin and were not formed during the 13,000 years the meteorite spent lying on Earth, this will have profound implications for our understanding of how life evolved in the solar system.”
Prof Colin Pillinger, of the Open University, who was behind Britain’s ill-fated Beagle 2 probe to the planet that was lost on Christmas Day 2003, said: “This is good quality work and more compelling evidence to add to the mix. These guys have been plugging away at this for years. It is a very careful study by very reputable people.”  The Nasa study, led by Kathie Thomas-Keprta, found carbonate discs and tiny magnetite crystals inside the space rock. Scientists were able to use high resolution electron microscopes that were not available 13 years ago.  They concluded “unusual chemical and physical properties” in the meteorite were “intimately associated within and throughout these carbonate disks”. That, they said, was evidence of interaction with water on Mars more than 3.5 billion years ago.  Nasa is expected to announce the findings, from its Johnson Space Centre in Houston, Texas, later this week.

Obama: Swine flu a national emergency

October 25th, 2009

Swine Flu Emergency

WASHINGTON (AP) — President Obama declared the swine flu outbreak a national emergency, giving his health chief the power to let hospitals move emergency rooms offsite to speed treatment and protect noninfected patients.

The declaration, signed Friday night and announced Saturday, comes with the disease more prevalent than ever in the country and production delays undercutting the government’s initial, optimistic estimates that as many as 120 million doses of the vaccine could be available by mid-October.

Health authorities say more than 1,000 people in the United States, including almost 100 children, have died from the strain of flu known as H1N1, and 46 states have widespread flu activity. So far only 11 million doses have gone out to health departments, doctor’s offices and other providers, according to the Centers for Disease Control and Prevention officials.

Administration officials said the declaration was a pre-emptive move designed to make decisions easier when they need to be made. Officials said the move was not in response to any single development.

Health and Human Services Secretary Kathleen Sebelius now has authority to bypass federal rules when opening alternative care sites, such as offsite hospital centers at schools or community centers if hospitals seek permission.

Some hospitals have opened drive-thrus and drive-up tent clinics to screen and treat swine flu patients. The idea is to keep infectious people out of regular emergency rooms and away from other sick patients.

Hospitals could modify patient rules — for example, requiring them to give less information during a hectic time — to quicken access to treatment, with government approval, under the declaration.

Hitting early, swine flu claims 11 more kids in US

October 17th, 2009


As the swine flu outbreak strikes the U.S. early and hard, health officials note a worrisome number of child deaths and warn that supplies of vaccine will remain scarce for at least the next couple of weeks.

Delays in producing the vaccine mean 28 million to 30 million doses, at most, will be divided around the country by the end of the month, not the 40 million-plus states had been expecting. The new count from the Centers for Disease Control and Prevention means anxiously awaited flu-shot clinics in some parts of the U.S. may have to be postponed.

It also delays efforts to blunt increasing infections. Overall, what CDC calls the 2009 H1N1 flu is causing widespread disease in 41 states, and about 6 percent of all doctor visits are for flu-like illness — levels not normally seen until much later in the fall.

Federal health officials said Friday 11 more children have died in the past week because of the virus.The Centers for Disease Control and Prevention says about half of the child deaths since September have been among teenagers. And overall for the country, deaths from pneumonia and flu-like illnesses have passed what CDC considers an epidemic level.
“These are very sobering statistics,” says the CDC’s Dr. Anne Schuchat.
This new strain is different from regular winter flu because it strikes the young far more than the old, and child deaths are drawing particular attention. Eighty-six children have died of swine flu in the U.S. since it burst on the scene last spring — 43 of those deaths reported in September and early October alone, said Schuchat.

Global Warming Is Real People

Global Warming Arctic Ice

Arctic ice to vanish in summer, report says

New data released Thursday suggests that the Arctic Ocean will be “largely ice free” during summer within a decade.
The report, complied by the UK-based Catlin Arctic Survey and the World Wildlife Fund (WWF), is the latest research into ice thickness in the Arctic.
Researchers predict that within 20 years ice cover will be completely gone during the warmer months.
The expedition, which was completed in May, was led by UK explorer Pen Hadow.
He and his team collected data by manually drilling into the ice and noting its thickness along a 450-kilometer route across the northern part of the Beaufort Sea.
They found that the area surveyed was comprised almost exclusively of first year ice.
Scientists think this is significant because traditionally the region has been made up of much older, thicker ice.
“Discovering this area of younger ice provides another body of information that supports the rapidly emerging scientific consensus that it’s going to be nearer 10 years from now that we will see roughly 80-85 percent free waters in the Arctic Ocean,” Hadow told CNN.
Measurements taken by Hadow and his team report that the ice-floes were on average 1.8 meters thick — which, according to scientists, is too thin to survive next summer’s ice melt.

Ford Engine Ignition Replaces Spark Plugs With Laser

July 14th, 2009

Green Spark Plug

Story and photo via ClimateBiz.com.

Ford Motor Co. and researchers at the University of Liverpool are developing a car ignition system that swaps spark plugs for a laser beam to start vehicles while generating fewer greenhouse gas emissions.

The team has just received nearly £200,000 (US$320,000) in grants to test the technology from the Carbon Trust, a government funded entity charged with helping businesses in the transition to a low carbon economy. The award is part of the Carbon Trust’s Applied Research grant that supports the development of low carbon technologies.

Ford reportedly plans to install the laser ignitions in a select range of vehicles in the next few years before expanding the laser ignitions on a larger scale. The technology works like this: The laser is quickly directed toward the combustion chamber where the fuel is most concentrated, allowing the engine to run on a more efficient mix of fuel and air. Bigger diameter valves that improve engine gas flow could be used in such a system because the thin fiber optic cable delivering the laser beam is smaller than a spark plug. The laser is also more reliable than a traditional spark plug.

The laser ignition may also overcome a significant barrier to widespread adoption of biofuels — starting the vehicle when the engine is cold. According to the Telegraph, reflecting part of the laser back from inside the cylinder can deliver information on fuel type and ignition level to allow vehicles to optimally adjust the air/fuel mix.

“Laser ignition is a really exciting technology because it improves the efficiency of petrol cars and could, in the future, speed the uptake of cars run on biofuels derived from sustainable organic materials such as algae,” Mark Williamson, the Carbon Trust’s director of innovations, said in a statement.
