Stressed-DNA repair protein identified | KurzweilAI - 0 views

  •  
    Vera Gorbunova and Andrei Seluanov of the University of Rochester have found that human cells undergoing oxidative stress caused by environmental chemicals or routine cellular processes produce a protein (SIRT6) that stimulates cells to repair DNA double-strand breaks, thought to be associated with premature aging and cancer. The team first measured levels of SIRT6 in stressed cells, then treated a second group of stressed cells with a drug that deactivates the protein. DNA repair in the second group stopped, confirming SIRT6′s role.  The team also found that SIRT6 acts in concert with another protein, called PARP1, to make the repairs. Furthermore, the team found that increased levels of SIRT6 lead to faster DNA repair. They suspect that the protein acts as a "master regulator," coordinating stress and DNA repair activities.

    October 24, 2008 - Google Tech Talks June 16, 2008 ABSTRACT Explore the brain's amazing ability to change throughout a person's life. This phenomenon-called neuroplasticty-is the science behind brain fitness, and it has been called one of the most extraordinary scientific discoveries of the 20th century. PBS had recently aired this special, The Brain Fitness Program, which explains the brain's complexities in a way that both scientists and people with no scientific background can appreciate. This is opportunity to learn more about how our minds work-and to find out more about the latest in cutting-edge brain research, from the founder of Posit Science and creator of the Brain Fitness Program software, Dr. Michael Merzenich. Speaker: Dr. Michael Merzenich, Ph.D. Michael M. Merzenich, PhD: Chief Scientific Officer Dr. Merzenich leads the company's scientific team. For more than three decades, Dr. Merzenich has been a leading pioneer in brain plasticity research. He is the Francis A. Sooy Professor at the Keck Center for Integrative Neurosciences at UCSF. Dr. Merzenich is a member of the National Academy of Sciences. He is the recipient of numerous awards and prizes, including the Ipsen Prize, Zulch Prize of the Max Planck Institute, Thomas Alva Edison Patent Award and Purkinje Medal. Dr. Merzenich has published more than 200 articles, including many in leading peer-reviewed journals, such as Science and Nature. His work is also often covered in the popular press, including the New York Times, the Wall Street Journal, Time and Newsweek. He has appeared on Sixty Minutes II, CBS Evening News and Good Morning America. In the late 1980s, Dr. Merzenich was on the team that invented the cochlear implant, now distributed by market leader Advanced Bionics. In 1996, Dr. Merzenich was the founding CEO of Scientific Learning Corporation (Nasdaq: SCIL), which markets and distributes software that applies principles of brain plasticity to assist children with language

Natural brain state is primed to learn - life - 19 August 2011 - New Scientist - 0 views

    Apply the electrodes... Externally modulating the brain's activity can boost its performance. The easiest way to manipulate the brain is through transcranial direct current stimulation (tDCS), which involves applying electrodes directly to the head to influence neuron activity with an electric current. Roi Cohen Kadosh's team at the University of Oxford showed last year that targeting tDCS at the brain's right parietal lobe can boost a person's arithmetic ability - the effects were still apparent six months after the tDCS session (newscientist.com/article/dn19679). More recently, Richard Chi and Allan Snyder at the University of Sydney, Australia, demonstrated that tDCS can improve a person's insight. The pair applied tDCS to volunteers' anterior frontal lobes - regions known to play a role in how we perceive the world - and found the participants were three times as likely as normal to complete a problem-solving task (newscientist.com/article/dn20080). Brain stimulation can also boost a person's learning abilities, according to Agnes Flöel's team at the University of Münster in Germany. Twenty minutes of tDCS to a part of the brain called the left perisylvian area was enough to speed up and improve language learning in a group of 19 volunteers (Journal of Cognitive Neuroscience, DOI: 10.1162/jocn.2008.20098). Using the same technique to stimulate the brain's motor cortex, meanwhile, can enhance a person's ability to learn a movement-based skill (Proceedings of the National Academy of Sciences, DOI: 10.1073/pnas.0805413106).

New laser technology could revolutionize communications | KurzweilAI - 0 views

  •  
    Engineers at Stevens Institute of Technology have developed a technique to optically modulate the frequency of a laser beam and create a signal that is disrupted significantly less by environmental factors, says Dr. Rainer Martini. The research provides for enhanced optical communications, allowing mobile units not tied to fiber optic cable to communicate in the range of 100 GHz and beyond, the equivalent of 100 gigabytes of data per second. Eventually, the team hopes to extend the reach into the terahertz spectrum. The frequency or amplitude modulation of middle infrared quantum cascade lasers has been limited by electronics, which are barely capable of accepting frequencies of up to 10 GHz by switching a signal on and off.  Marini and his team have developed a method to optically induce fast amplitude modulation in a quantum cascade laser to control the laser's intensity. Their amplitude modulation system employed a second laser to modulate the amplitude of the middle infrared laser, using light to control light. The current detector is only capable of detecting frequencies up to 10 GHz, but Dr. Martini is confident that a new detector will make the system capable of much higher frequencies. With an optical system that is stable enough, satellites may one day convert to laser technology, resulting in a more mobile military and super-sensitive scanners, as well as faster Internet for the masses, says Martini.

Antihydrogen Atoms Stored for the First Time - 0 views

  •  
    Large quantities of antihydrogen atoms were first made at CERN eight years ago by two other teams. Although they made antimatter they couldn't store it, because the anti-atoms touched the ordinary-matter walls of the experiments within millionths of a second after forming and were instantly annihilated-completely destroyed by conversion to energy and other particles.

New Scientist TV: Become a virtual film-maker - 0 views

  •  
    Motion controllers used in gaming systems like the Nintendo Wii revolutionised how video games are played. But now a similar device that's more precise - and even works when an object is in its way - will let you try something more futuristic: making movies in virtual environments. Matt Bett and his team from Abertay University in the UK developed the new motion controller that uses electromagnetic sensors to track its 3D position. The location is then mapped in real time to a virtual video camera on a screen (see video above). By moving the controller around, the camera moves around the scene like a real camera on a rig or it can be fixed to a virtual tripod.

Researchers create light from 'almost nothing' - 0 views

  •  
    (PhysOrg.com) -- A group of physicists working out of Chalmers University of Technology in Gothenburg, Sweden, have succeeded in proving what was until now, just theory; and that is, that visible photons could be produced from the virtual particles that have been thought to exist in a quantum vacuum. In a paper published on arXiv, the team describes how they used a specially created circuit called a superconducting quantum interference device (SQUID) to modulate a bit of wire length at a roughly five percent of the speed of light, to produce visible "sparks" from the nothingness of a vacuum.
