Microsoft shows off “snippet” of Windows 7 at D6, reveals multi-touch support

March 24th, 2008 by Mylo

p1000159.jpgBill Gates and Steve Ballmer got on stage at D6 with Walt and Kara to talk… Microsoft, of course. While the company is still being rather coy about Windows 7 — some have blamed loose lips early on in Vista development for saddling the OS with too high of expectations and making things difficult for developers — they were nice enough to show off what Ballmer called “the smallest snippet” of Windows 7. The big reveal was multi-touch support, which utilizes technology developed by the Surface team. The taskbar seems to have been reworked a bit, and the demo was running live on a Dell Latitude XT tablet. Apparently Microsoft is reworking the whole user interface with a multitouch experience in mind. Steve reiterated the “three years after Vista” mantra for availability. Not exactly earth-shattering, but we’ll take what we can get at this point.

The brains of dead Russian geniuses:

March 20th, 2008 by Mylo

What makes a man a genius? Russian neuroscientists were pondering this exactly this question in the early 1900s and did exactly what seemed sensible at the time - they collected and dissected the brains of some of the greatest cultural figures in a huge collection called ‘The Pantheon of Brains’.

It’s a fascinating story told in a recent article published in the medical journal Brain. Amazingly, the last brain was only added in 1989.

Rather fittingly, the collection contains the brains of some of the Russia’s greatest psychologists and neuroscientists and has many curious aspects to it, such as the mysterious death of its founder. After death, his brain was immediately added to the collection.

In 1927, Bekhterev came up with a plan to organize ‘The Pantheon of Brains’ in Leningrad in order to collect elite brains. It was a severe irony of fate that precisely when the question about creating the Pantheon had been positively solved, the very initiator of this creation, Bekhterev, suddenly passed away. The circumstances are still questionable.On December 17, 1927, the First All-Union Congress of Neuropathologists and Psychiatrists was held in Moscow. Bekhterev, along with L. S. Minor and G. I. Rossolimo, was elected as honourable chairmen of the congress. On December 23rd, the last day of the congress, Bekhterev gave a presentation during the afternoon session. In the evening, symptoms of a gastrointestinal disorder started and 24 hs later, Bekhterev died of (as officially stated) acute heart failure. Without any further post-mortem pathoanatomical investigation, his brain was removed, in accordance with his will, and his body was cremated the next day. However, the idea did not fade away.

In 1928, the neuroanatomical laboratory of Vogt and his Russian colleagues were reorganized into the Moscow Brain Research Institute, where the structured collecting and mapping of the brains of famous Russians started. Bekhterev did not see his plan come to fruition, but his own brain enriched the collection of the Moscow Institute (the weight of his brain was 1720g). The collection acquired the brains of Soviet politicians, famous writers, poets, musicians, etc. Read the rest of this entry »

Study Links Genetic Footprint Of Embryonic Stem Cells To Cancer Cells

March 5th, 2008 by Mylo

A new study suggests that a genetic fingerprint associated with normal embryonic stem cells may be important for the development and function of cancer stem cells. The research in Cell Stem Cell demonstrates that embryonic stem cells and multiple types of human cancer cells share a genetic expression pattern that is repressed in normal differentiated cells, a finding that may have significant clinical implications for cancer therapeutics.

“Self-renewal is a hallmark of stem cells and cancer, but existence of a shared stemness program remains controversial,” explains study co-author, Dr. Howard Y. Chang from Stanford University. Dr. Chang, Dr. Eran Segal from the Weizmann Institute in Israel and their colleagues constructed a gene module map to systematically relate transcriptional programs in embryonic stem cells (ESCs), adult tissue stem cells and human cancers.

The researchers identified two predominant gene modules that distinguish ESCs and adult tissue stem cells. “Importantly, the ESC-like transcriptional program was activated in diverse human epithelial cancers and strongly predicted metastasis and death,” says Dr. Segal. Conversely, the adult tissue stem gene module had an opposite pattern, activated in normal tissues relative to cancer and repressed in various human cancers when compared to normal tissues.
