Discovery may contain metal from asteroid crash, Baylor University researcher says. A mysterious large mass of material has been discovered beneath the largest crater in our solar system – the Moon’s South Pole-Aitken basin – and may contain metal from the asteroid that crashed into the Moon and formed the crater, according to a Baylor University study.

“Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That’s roughly how much unexpected mass we detected,” said lead author Peter B. James,

Viable competitor for copper in 5G wireless and other applications. Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University’s Brown School of Engineering. They’re also tougher, more flexible and can essentially be painted onto devices.

The Rice lab of chemical and biomolecular engineer Matteo Pasquali tested antennas made of “shear-aligned” nanotube films...

Research provides a possible new reason why human disease burden increases so sharply from the sixth decade of life onward as health-protective mechanisms disappear.

Claes Wahlestedt, M.D., Ph.D., professor of psychiatry and behavioral sciences and associate dean for therapeutic innovation at the University of Miami Miller School of Medicine, is senior author of a new study – Longevity Related Molecular Pathways Are Subject to Midlife ‘Switch’ in Humans – published today in Aging Cell.

About 20% of breast cancers make abnormally high levels of a protein called human epidermal growth factor receptor 2 (HER2). When displayed on the surface of cancer cells, this signaling protein helps them proliferate uncontrollably and is linked with a poor prognosis. Now, researchers have developed a DNA nanorobot that recognizes HER2 on breast cancer cells, targeting them for destruction.

Current therapies for HER2-positive breast cancer include monoclonal antibodies, such as trastuzumab, that bind to HER2 on cells and direct it to the lysosome – an organelle that degrades biomolecules. Lowering the levels of HER2 slows cancer cell proliferation and triggers cell death...
