A research team at Japan’s RIKEN Center for Developmental Biology synthesized a stem-cell-derived pituitary gland. The pituitary gland is a small organ at the base of the brain that produces many important hormones and is a key part of the body’s endocrine system. It’s especially crucial during early development, so the ability to simulate its …
Spaceflightnow – Two months after a rare Russian launch failure, an unmanned Progress cargo ship loaded with 2.9 tons of supplies and equipment bound for the International Space Station rocketed smoothly into orbit Sunday, clearing the way for the resumption of manned Soyuz flights next month, just in time for the lab’s partners to avoid …
Whitesands is a wholly owned operating company holding, dedicated to developing Petrobank’s heavy oil and oil sands assets using our patented THAI® technology. Whitesands has a 100 percent working interest in over 46,000 acres of oil sands leases in northern Alberta. We are currently in the final stages of regulatory approval. The initial May River …
Center for Responsible Nanotechnology – Nano-channels for molecule delivery – and construction? Chris Phoenix suggests extending recent research into a larger molecularly precise construction system. Molecules can be delivered through a tiny channel templated by one strand of DNA. Ohio State university uses electricity to “shoot” bits of therapeutic biomolecules through a tiny channel and …
While many in Russia and the West see Mr. Brezhnev’s reign as one of stagnant totalitarianism, for Mr. Putin’s spokesman the analogy isn’t a bad thing at all. “Brezhnev wasn’t a minus for the history of our country, he was a huge plus,” Dmitry Peskov told Dozhd, an independent Russian television network. “He laid the …
The World Nuclear Association increased its world nuclear 2030 growth forecast by 2 per cent from its 2009 report. Today’s generating capacity of 364 gigawatts could rise to as much as 790 gigawatts over the next two decades, and high uranium prices are encouraging exploration and production of the raw material for nuclear fuel. A …
Scientists at A*STAR’s Institute of Molecular and Cell Biology (IMCB) have made a landmark discovery in the battle against the rapid spread of aggressive cancers associated with PRL-3 oncoprotein . Contrary to the current accepted theory that antibodies can only bind to cancer proteins found on the cancer cell surface, the IMCB team led by …
Peidong Yang, a chemist with Berkeley Lab’s Materials Sciences Division, led the development of a solution-based technique for fabricating core/shell nanowire solar cells using the semiconductors cadmium sulfide for the core and copper sulfide for the shell. These inexpensive and easy-to-make nanowire solar cells boasted open-circuit voltage and fill factor values superior to conventional planar …
Looking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers report in the August 12 issue of the journal Science, clocking in at …
Space Review – Today, no true air-breathing spaceplanes or reusable boosters yet exist, but there is now renewed interest in air-breathing technology. At the same time, remarkable launch cost reductions in more conventional boosters are imminent due to the efforts of SpaceX and other firms. There is now steady progress in actual testing of hypersonic …
Scientists at Pacific Northwest National Laboratory’s Center for Molecular Electrocatalysis and Villanova University designed a nickel-based complex that more than doubled previously reported hydrogen gas production rates and increased the energy efficiency of the reaction. Additionally, the team found that adding water to the reaction significantly increased the reaction speed. As a result of the …
