‘The God Particle’ Nearly, But Not Quite

Simulation - Higgs Event

Scientists at the European Organisation for Nuclear Research – CERN –  say they have found signs of – although not yet conclusively discovered – the Higgs boson, an elementary particle which is the missing link in the Standard Model of physics. Anticipation amongst physicists has to be at an all time high. The famed particle is the missing link in current theories of physics, used to explain how everything gains its mass. Rumors have been crashing about the scientific community for weeks on these findings. Finding the Higgs is the central goal for the $10bn Large Hadron Collider – a 27km, 17mile circumference accelerator ring of superconducting magnets – designed to re-create the conditions just after the Big Bang in an attempt to answer fundamental questions of science and indeed the Universe itself.

NASA's Five Finger Discount? Missing Astromaterials End Up in Bill Clinton's Treasure Trove

NASA's Missing Astromaterials It seems researchers have sticky fingers when it comes to NASA’s moon rocks and meteorites, as hundreds of samples have gone missing after being loaned out by the US space agency, an audit has revealed. NASA inspector General Paul Martin issued a report detailing weak points in the US space agency such as the agency making loans to researchers who never use the samples, or simply lose track of rare pieces dating back to the first trip to the Moon in 1969. According to NASA records, between 1970 and 2007, 517 loaned astromaterials have been lost or stolen” the report said.  In 2002, 218 samples from the Moon and meteorites were stolen from Johnson Space Centre in Houston but later returned. Earlier this year, one moon rock that had been given up for lost was discovered in a box of former president Bill Clinton’s files and memorabilia, stored at an Arkansas library. Astromaterials include Moon rocks and soil; meteorites from asteroids, Mars, and the Moon; ions from the outer layers of the Sun; dust from comets and interstellar space; and cosmic dust from Earth’s stratosphere.

Alzheimer’s Vaccine A Big Step Closer

Posted: December 9th, 2011 | Author: | Filed under: mcsixtyfive | Tags: , , , , , , , , , | Comments Off on Alzheimer’s Vaccine A Big Step Closer

MicrotubleResearchers  have had success with a vaccine that could ultimately slow down advanced Alzheimer’s disease in humans. The team from Sydney University have published – PLoS ONE – details of a study which shows the vaccine slows one type of dementia by stopping neuro-fibre tangling. Associate Professor Lars Ittner from Sydney University – Alzheimer’s and Parkinson’s Disease Laboratory says the study was conducted on mice that were already developing the condition. Ittner said it was the first time researchers had proved a vaccine that targeted the tau protien in mice that had already developed the disease. Ittner says that their approach was different, until now most research has targeted the  tau protiens in younger animals, prior to the onset of Alzheimer’s disease. “What we attempted to do was to work with older mice with a lot of damage. Because in people, by the time they realise their symptoms are Alzheimer’s disease, a lot of damage has already been done.” said Ittner. The researchers say their novel approach worked, producing some of the most improved results so far recorded in mice with advanced dementia.

Kepler Finds Earth-like Planet

Kepler 22b

Astronomers with NASA’s Kepler mission have confirmed the existence of an Earth-like planet in a “habitable zone” around a star not unlike our own. The planet, Kepler 22-b, lies about 600 light years away, about two-and-a-half times the size of Earth, with a temperature of about 22 degrees Celsius, allowing liquid water to exist on the surface. Its year is about 290 days long. This is the first time the Kepler mission has detected a potentially habitable world orbiting a Sun-like star, scientists reported in findings to be published in The Astrophysical Journal. Scientists admit they do not yet know if Kepler 22-b is made mostly of rock, gas or liquid.

Global Warming: Atmospheric CO2 Link Questioned

Posted: November 25th, 2011 | Author: | Filed under: mcsixtyfive | Tags: , , , , , , , , , | Comments Off on Global Warming: Atmospheric CO2 Link Questioned

Global Warming Atmospheric CO2 Link QuestionedHigh levels of carbon dioxide in the atmosphere may have less of an impact on the rate of global warming than previously feared, a new study suggests. Associate Professor Schmittner notes that many previous studies only looked at periods spanning from 1850 to today, thus not taking into account a fully integrated palaeoclimate data on a global scale. The authors of the study stress that global warming is real and that increases in atmospheric CO2, which has doubled from pre-industrial standards, will have multiple serious impacts. But more severe estimates that predict temperatures could rise up to an average of 10 degrees Celsius are unlikely, the researchers report in the journal Science.  The new study suggests temperatures will rise on average 2.3 degrees under the same conditions. Scientists have long struggled to quantify climate sensitivity, or how the Earth will respond to projected increases in carbon dioxide, the main greenhouse gas M★S READ MORE
