“Virtual batteries” could lead to cheaper, cleaner power

Coordinating smart appliances and electric cars may help balance supply and demand in the power grid. In the power grid, supply and demand need to match exactly. If consumers demand more power than producers can supply, or if producers provide more power than consumers need, the result can be rolling blackouts. Power producers usually keep … Continue reading ““Virtual batteries” could lead to cheaper, cleaner power”

Critical step found in DNA repair, cellular aging

Unraveling the mysteries of aging. Research conducted by David Sinclair and colleagues shows that, in mice, treatment with the NAD precursor NMN mitigates age-related DNA damage and averts DNA damage from radiation exposure. DNA repair is essential for cell vitality, cell survival, and cancer prevention, yet cells’ ability to patch up damaged DNA declines with … Continue reading “Critical step found in DNA repair, cellular aging”

New 3-D-printed device mimics the Goldbug Beetle, which changes color when prodded.

New 3-D-printed device mimics the goldbug beetle, which changes color when prodded. In this age of smartphones and tablet computers, touch-sensitive surfaces are everywhere. They’re also brittle, as people with cracked phone screens everywhere can attest. Covering a robot — or an airplane or a bridge — with sensors will require a technology that is … Continue reading “New 3-D-printed device mimics the Goldbug Beetle, which changes color when prodded.”

Security for multirobot systems

Multi-robot networks use wireless communication to provide wide-ranging services such as aerial surveillance and unmanned delivery. However, effective coordination between multiple robots requires trust, making them particularly vulnerable to cyber-attacks. Specifically, such networks can be gravely disrupted by the Sybil attack, where even a single malicious robot can spoof a large number of fake clients. … Continue reading “Security for multirobot systems”
