Quantum physics first: Physicists measure without distorting - 1 views

  •  
    With this new experiment, the researchers have succeeded for the first time in experimentally reconstructing full trajectories which provide a description of how light particles move through the two slits and form an interference pattern. Their technique builds on a new theory of weak measurement that was developed by Yakir Aharonov's group at Tel Aviv University. Howard Wiseman of Griffith University proposed that it might be possible to measure the direction a photon (particle of light) was moving, conditioned upon where the photon is found. By combining information about the photon's direction at many different points, one could construct its entire flow pattern ie. the trajectories it takes to a screen.

Researchers chart long-shrouded glacial reaches of Antarctica: Huge rivers of ice are f... - 0 views

  •  
    ScienceDaily (Aug. 19, 2011) - A vast network of previously unmapped glaciers on the move from thousands of miles inland to the Antarctic coast has been charted for the first time by UC Irvine scientists. The findings will be critical to tracking future sea rise from climate change.

New, tighter timeline confirms ancient volcanism aligned with dinosaurs' extinction | E... - 0 views

  •  
    A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth's non-avian dinosaurs, according to new research from Princeton University. A primeval volcanic range in western India known as the Deccan Traps, which were once three times larger than France, began its main phase of eruptions roughly 250,000 years before the Cretaceous-Paleogene, or K-Pg, extinction event, the researchers report in the journal Science. For the next 750,000 years, the volcanoes unleashed more than 1.1 million cubic kilometers (264,000 cubic miles) of lava. The main phase of eruptions comprised about 80-90 percent of the total volume of the Deccan Traps' lava flow and followed a substantially weaker first phase that began about 1 million years earlier.

Inorganic Pharmaceutical Chemistry - 0 views

  •  
    This book contains excellent written text for the students of B.Pharm. 1st Year. It covers whole syllabus prescribed by the AICTE all over the India, and new syllabus prescribed by the GBTU (Lucknow) and MMTU (Noida). This is the first book which is written according to it. It contains all the important questions of each chapter, along with important objective questions, which helps students to revise their knowledge in the subject. This book contains a complete and comprehensive material on various topics of pharmaceutical chemistry. The topics have been explained in such a simple way that students need not study any other book for this subject. Various tables are provided for important topics, apart from that flow charts are used in simple language, which looks like simplified notes.

Warning: Gravity is "Only a Theory" by Ellery Schempp - 2005 - 0 views

  • Anti-gravity papers are routinely rejected from peer-reviewed journals, and scientists who propose anti-gravity quickly lose their funding. Universal gravity theory is just a way to keep the grant money flowing.

Traces of the past: Computer algorithm able to 'read' memories - 0 views

  • To explore how such memories are recorded, the researchers showed ten volunteers three short films and asked them to memorise what they saw. The films were very simple, sharing a number of similar features - all included a woman carrying out an everyday task in a typical urban street, and each film was the same length, seven seconds long. For example, one film showed a woman drinking coffee from a paper cup in the street before discarding the cup in a litter bin; another film showed a (different) woman posting a letter. The volunteers were then asked to recall each of the films in turn whilst inside an fMRI scanner, which records brain activity by measuring changes in blood flow within the brain. A computer algorithm then studied the patterns and had to identify which film the volunteer was recalling purely by looking at the pattern of their brain activity. The results are published in the journal Current Biology. "The algorithm was able to predict correctly which of the three films the volunteer was recalling significantly above what would be expected by chance," explains Martin Chadwick, lead author of the study. "This suggests that our memories are recorded in a regular pattern." Although a whole network of brain areas support memory, the researchers focused their study on the medial temporal lobe, an area deep within the brain believed to be most heavily involved in episodic memory. It includes the hippocampus - an area which Professor Maguire and colleagues have studied extensively in the past. They found that the key areas involved in recording the memories were the hippocampus and its immediate neighbours. However, the computer algorithm performed best when analysing activity in the hippocampus itself, suggesting that this is the most important region for recording episodic memories. In particular, three areas of the hippocampus - the rear right and the front left and front right areas - seemed to be involved consistently across all participants. The rear right area had been implicated in the earlier study, further enforcing the idea that this is where spatial information is recorded. However, it is still not clear what role the front two regions play.

    Computer programs have been able to predict which of three short films a person is thinking about, just by looking at their brain activity. The research, conducted by scientists at the Wellcome Trust Centre for Neuroimaging at UCL (University College London), provides further insight into how our memories are recorded.

Steadier Traffic Flow Improves Health of Local Infants, Researchers Say - 0 views

  •  
    "The creation of E-ZPass lanes over the past 15 years has significantly improved the health of newborn babies living near highways in the Northeast, according to a Columbia study. The researchers found that reductions in traffic congestion generated by E-ZPass lanes reduced premature birthrates by 10.8 percent and low birth weight by 11.8 percent among infants born within 2 kilometers of toll plazas. The net effect has led to hundreds of millions of dollars in saved medical costs."

How Does A Turbine Work? - 0 views

  •  
    A turbine is a machine used to convert energy generated by moving liquid, gas or air into work. For example, the energy produced by fast flowing water is made to spin a rotating shaft by pushing on the angled blades set around a wheel mounted on the shaft, and this action produces the required work. ...
