Galaxy Clusters Formed Early

Only one billion years after the Big Bang, clusters of galaxies were already forming. This discovery pushes back the age of the youngest known galaxy cluster by a third, and shows that the largest astronomical objects in ...

Robots that walk like humans

Three independent research teams, including one from MIT, have built walking robots that mimic humans in terms of their gait, energy-efficiency, and control. The MIT robot also demonstrates a new learning system that allows ...

SRAM technology with 0.8V operation voltage

Hitachi, Ltd.and Renesas Technology Corp. announced that they have developed low-voltage embedded SRAM technology for SoC's (system-on-a-chip) beyond the 90-nm process node. Using new circuit techniques, the power lines of ...

Green Tea Extract Shows Potential as an Anti-Cancer Agent

A study on bladder cancer cell lines showed that green tea extract has potential as an anti‑cancer agent, proving for the first time that it is able to target cancer cells while leaving healthy cells alone. The study, ...

The Oldest Homo sapiens

When the bones of two early humans were found in 1967 near Kibish, Ethiopia, they were thought to be 130,000 years old. A few years ago, researchers found 154,000- to 160,000-year-old human bones at Herto, Ethiopia. Now, ...

Super-heavy nuclei take shape in 'extreme' new theories

Advanced computational methods and supporting experiments, including work performed at the Department of Energy's Oak Ridge National Laboratory, are giving scientists a better understanding of the nature and stability of ...
