    Physicists create ‘Negative Mass’

    April 17, 2017, Categories  Astronomy/Space

    Hypothetically, matter can have negative mass in the same sense that an electric charge can be either negative or positive. With negative mass, if you push something, it accelerates toward you. Forbes said, "It looks like the rubidium hits an invisible wall." (stock image). Credit: © ktsdesign / Fotolia

    Experimental technique can help probe phenomena in astrophysics and cosmology. Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It accelerates backwards...

    A team of researchers with the Institute for Integrative Nanosciences in Germany has tested the possibility of using sperm cells to deliver drugs to cancerous tumors in female patients. The group describes how such a technique might work, their initial test results and what they learned from their experiments. In this new effort, they looked into the idea of using a natural carrier to deliver helpful drugs to specified targets—sperm cells delivering drugs guided to tumors and other problem sites in the female reproductive tract...

    Dendritic cell vaccine supports further study in larger trials. A phase 1 study of 11 patients with glioblastoma who received injections of an investigational vaccine therapy and an approved chemotherapy showed the combination to be well tolerated while also resulting in unexpectedly significant survival increases, researchers at the Duke Cancer Institute report. Patients treated with the study drug (dose-intensified temozolomide and vaccines) were continuously monitored for toxicity and adverse events. Study patients experienced known side effects with temozolomide, including nausea, lymphopenia, thrombocytopenia and fatigue.

    There were no treatment limiting a...

    Computers Create Recipe for 2 new Magnetic Materials

    1. A microscopic look at the atomic structure of a cobalt-manganese-titanium mixture (Co2MnTi) that is one of the newly predicted and manufactured magnetic materials. Each color shows the distribution of a different element. The uniformity for each material matches the predictions for a stable three-element material. 2. A microscopic look at the atomic structure of a manganese-platinum-palladium mixture (Mn2PtPd), that is one of the newly predicted and manufactured magnetic materials. Each color shows the distribution of a different element. The uniformity for each material -- with the exception the small spots indicating a different phase state -- matches the predictions for a stable three-element material.
