Triceratops never existed?
The uncertainty of science, again! The three-horned dinosaur triceratops might never have existed, paleontologists say. Instead, it might simply have been the youthful stage of another less well know dinosaur called torosaurus.
Pluto might be larger than Eris after all
The uncertainty of science! Eris, the distant planet in the Kuiper belt, had been thought to be larger than Pluto. Now astronomers have doubts.
Federal Budget Rollback Could Slash NIH Grant Success Rates
The squealing begins! NIH director warned researchers on Saturday that the House Republican budget plans could slash by half the funding rates for biomedical researchers.
AGU denies its climate science campaign is an attack on skeptics
I think this is good news: The American Geophysical Union today is denying its climate science project, Climate Q&A, is an attack on skeptics, as reported yesterday.
European plans to boost biofuels will hurt environment, say environmentalists
The law of unintended consequences strikes again! Nine environmental groups have found that the European Union’s plan to promote the use of biofuels over fossil fuels will actually damage the environment. Key quote:
The extra biofuels that Europe will use over the next decade will generate between 81 and 167 percent more carbon dioxide than fossil fuels, says the report.
China releases first photos from Chang’e 2
China today released the first photos taken by Chang’e 2, its second lunar orbiter launched on October 1. More here, including one image.
Global warming scientists to start campaign against skeptics
What could go wrong? The American Geophysical Union is going to announce tomorrow a public campaign by 700 scientists to attack any skepticism of global warming.
Update on Mount Merapi eruption
More on the continuing eruption of Mount Merapi in Indonesia. Key quote:
The Volcano Mitigation and Geological Disaster Agency warned of worse in store as magma pushed towards the surface from depths of 6-8km, compared with a maximum 2km deep when the mountain previously erupted in 2006. “This is the scenario I dislike the most, because the deepest magma is pushing up now,” said the agency’s chief, Surono. “The eruptions haven’t stopped, the tremors are getting stronger and one big explosion could be the result. I’ve never seen it act like this. We don’t know what to expect.”
Cassini goes into safe mode
Cassini went into safe mode on Tuesday, November 2nd. At the moment engineers expect it to take at least another week to get the spacecraft back to normal.
The first images of Deep Impact’s flyby of Comet Hartley 2
Here are the first images of Deep Impact’s flyby of Comet Hartley 2. The first is a montage, the sequence in time going clockwise. The second is a close-up of the second image.
The feature that I find most intriguing is the narrow smooth waist of the comet’s dogbone shape. The whole thing looks almost like a piece of taffy that’s being pulled apart.
An Early Warning System for Asteroid Impact
In a paper posted tonight on the Los Alamos astro-ph website, an astronomer is proposing an early warning system for asteroid impact. Key quote from the abstract:
This system, dubbed “Asteroid Terrestrial-impact Last Alert System” (ATLAS), comprises two observatories separated by about 100km that simultaneously scan the visible sky twice a night, and can be implemented immediately for relatively low cost. The sensitivity of ATLAS permits detection of 140m asteroids (100 Mton impact energy) three weeks before impact, and 50m asteroids a week before arrival. An ATLAS alarm, augmented by other observations, should result in a determination of impact location and time that is accurate to a few kilometers and a few seconds.
