Artist's impression of a black hole. Could an advanced alien civilization create a cosmic collider using such an object? (Courtesy: NASA/JPL-Caltech)Topics: Black Holes, Neutrinos, Particle Physics, Space, SETIHas an advanced alien civilization built a black-hole-powered particle accelerator to study physics at "Planck-scale" energies? And if such a cosmic collider is lurking in a corner of the universe, could we detect it here on Earth?Brian Lacki of the Institute for Advanced Studies in […]

3:00 AM | Come svelare i segreti della materia scura
Un segnale osservato sotto forma di raggi gamma è stato rivelato di recente dal centro della Via Lattea dietro il quale, forse, si potrebbe celare la scoperta che stiamo aspettando da tanto tempo (post1; post2; post3; post4). Se questi raggi-gamma sono davvero prodotti dalle interazioni di particelle di materia scura, allora essi potrebbero fornirci preziosi … Continue reading Come svelare i segreti della materia scura →

11:05 PM | How high is a winning cricket score?
I can't help thinking that the West Indies team got their run chase strategy wrong on Sunday night. They had a tricky task ahead of them. One might say the problem was one of their own making, judging from the rubbish that they served up to Guptill to hit at the end of tne New Zealand innings, but that was in the past. The fact was they had to chase down 393 in 50 overs. How does a team go about doing that? I would have thought that the obvious answer was 'in the same way that the […]

9:40 PM | Our solar system may have once harbored super-earths
Long before Mercury, Venus, Earth, and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths–planets larger than Earth but smaller than Neptune. If […]

8:40 PM | Simple Test May Detect Toxic Drugs Faster
Originally published: Mar 20 2015 - 2:15pm, Inside Science News ServiceBy: Ben P. Stein, Director(Inside Science) -- Testing whether a drug is safe and effective usually takes many years and millions of dollars. Now, researchers have discovered a surprisingly simple method that could quickly and inexpensively weed out many toxic drugs early in the testing process. The test simply explores how much a drug alters a cell's outer covering, or membrane.Pharmaceutical companies go to great lengths to […]

2:52 PM | Where Are They Now? Steve Hawley
Steve Hawley was the flight engineer on the STS-93 Columbia mission that carried Chandra into space in 1999. Before that he was on four previous shuttle flights, one in 1990 to deploy the Hubble Space Telescope, and one in 1997 to assist in making major upgrades and repairs to Hubble. His role in the deployment of two of the most productive telescopes ever has secured him an important place in the history of astronomy. At a recent symposium celebrating 15 years of Chandra Science, Steve sat […]
