New welding process opens up uses for formerly un-weldable lightweight alloy
Posted by Genevieve Klien in category: nanotechnology
Developed in the 1940s, AA7075 is an aluminum alloy that’s almost as strong as steel, yet it weighs just one third as much. Unfortunately its use has been limited, due to the fact that pieces of it couldn’t be securely welded together. That’s recently changed, however, thanks to the use of titanium carbide nanoparticles.

New Map of Dark Matter Breaks Scientists’ Understanding of Physics
Posted by Genevieve Klien in categories: cosmology, physics
What they found was surprising. The new map, published on the preprint server arXiv, suggests that the huge structure of dark matter in the universe formed more slowly that previously believed — results that “appear to challenge current understanding of the fundamental laws of physics,” according to the press release.
Road Ahead
But before physicists throw out the rulebook, Hikage cautioned that the new map needs to be corroborated.

Major Clinical Trial Links High Blood Pressure And Mild Cognitive Impairment
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
A new study says lowering blood pressure doesn’t reduce the risk for dementia, but it does lower the impact of mild cognitive impairment (MCI), which could be the next best thing in the study of dementia prevention.

New Oxford-developed tool reads the life histories of cancer cells
Posted by Genevieve Klien in categories: biotech/medical, genetics
Cancer is a complicated disease. Tumors are made up of many different types of cancer cells, and our current treatment techniques can’t always clear them all out. Now, a team of Oxford researchers has developed a way to track the genetic “life histories” of thousands of individual cancer cells at once, which may lead to more effective and personalized cancer treatments.
