Atomic bond types discernible in single-molecule images. 13 September 2012Last updated at 17:36 ET By Jason Palmer Science and technology reporter, BBC News The bonds at centre appear shorter than those at the edges, as more electrons are present in them A pioneering team from IBM in Zurich has published single-molecule images so detailed that the type of atomic bonds between their atoms can be discerned.
The same team took the first-ever single-molecule image in 2009 and more recently published images of a molecule shaped like the Olympic rings. The new work opens up the prospect of studying imperfections in the "wonder material" graphene or plotting where electrons go during chemical reactions. The images are published in Science. Children with older fathers and grandfathers 'live longer' 11 June 2012Last updated at 22:24 ET By Michelle Roberts Health editor, BBC News website Delaying fatherhood may offer survival advantages, say US scientists who have found children with older fathers and grandfathers appear to be "genetically programmed" to live longer.
Can hot water freeze faster than cold water? Boltzmann brain. A bust of Ludwig Boltzmann, for whom Boltzmann brains are named A Boltzmann brain is a hypothesized self aware entity which arises due to random fluctuations out of a state of chaos.
The idea is named for the physicist Ludwig Boltzmann (1844–1906), who advanced an idea that the universe is observed to be in a highly improbable non-equilibrium state because only when such states randomly occur can brains exist to be aware of the universe. The Boltzmann brains concept is often stated as a physical paradox. Timeline of the far future. Marijuana Cuts Lung Cancer Tumor Growth In Half, Study Shows. The active ingredient in marijuana cuts tumor growth in common lung cancer in half and significantly reduces the ability of the cancer to spread, say researchers at Harvard University who tested the chemical in both lab and mouse studies.
They say this is the first set of experiments to show that the compound, Delta-tetrahydrocannabinol (THC), inhibits EGF-induced growth and migration in epidermal growth factor receptor (EGFR) expressing non-small cell lung cancer cell lines. Lung cancers that over-express EGFR are usually highly aggressive and resistant to chemotherapy. Free Classes. Awesome Instructors. Inspiring Community.
Tech tycoons in asteroid mining venture. A group of hi-tech tycoons including Google's Larry Page and Eric Schmidt have teamed up with explorer and film-maker James Cameron in a venture to mine nearby asteroids, hoping to turn science fiction into real profits.
The megamillion dollar plan is to use commercially built robotic ships to squeeze rocket fuel and valuable minerals such as platinum and gold out of the rocks that routinely whizz by Earth, with the aim of having a space-based fuel station up and running by 2020. The inaugural step, to be achieved in the next 18 to 24 months, would be to launch the first of a series of private telescopes that would search for rich asteroid targets.
The entrepreneurs announcing the project in Seattle on Tuesday have a track record of making big money off ventures into space. Virtualizing storage for scale, resiliency, and efficiency - Building Windows 8. In this post, we are going to dive into a feature in the Windows 8 Developer Preview.
Storage Spaces are going to dramatically improve how you manage large volumes of storage at home (and work). We’ve all tried the gamut of storage solutions—from JBOD arrays, to RAID boxes, or NAS boxes. Many of us have been using Windows Home Server Drive Extender and have been hoping for an approach architected more closely as part of NTFS and integrated with Windows more directly. In building the Windows 8 storage improvements, we set out to do just that and developed Storage Spaces. Of course, the existing solutions you already use will continue to work fine in Windows 8, but we think you will appreciate this new feature and the flexible architecture.
By my own admission, I am a digital packrat. Windows 8 provides a new capability called Storage Spaces enabling just that. Organization of physical disks into storage pools, which can be easily expanded by simply adding disks. Flexible Remote Backup & Online Storage. Space firm about to make a big announcement. I take a stab at what it is.
I’m overwhelmed with work right now prepping for a half dozen different things, but I had to make some comment on a press release I just got in the mail.
Here’s the important bit [emphasis mine]: Join visionary Peter H. Diamandis, M.D.; leading commercial space entrepreneur Eric Anderson; former NASA Mars mission manager Chris Lewicki; and planetary scientist & veteran NASA astronaut Tom Jones, Ph.D. on Tuesday, April 24 at 10:30 a.m. PDT in Seattle, or via webcast, as they unveil a new space venture with a mission to help ensure humanity’s prosperity.Supported by an impressive investor and advisor group, including Google’s Larry Page & Eric Schmidt, Ph.D.; film maker & explorer James Cameron; Chairman of Intentional Software Corporation and Microsoft’s former Chief Software Architect Charles Simonyi, Ph.D.; Founder of Sherpalo and Google Board of Directors founding member K.
