Nanodevice Defeats Drug Resistance

Researchers from MIT have developed a new nanodevice that can defeat drug resistance by turning off the drug resistant gene and then releasing cancer drugs against the disarmed tumors. Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers […]

New Circuit Reduces Power Leakage

Engineers have developed a new transmitter design that reduces off-state leakage 100-fold. At the same time, this new technology provides adequate power for Bluetooth transmission, or for the even longer-range 802.15.4 wireless-communication protocol. At this year’s Consumer Electronics Show in Las Vegas, the big theme was the “Internet of things” — the idea that everything […]

New Approach Could Make Multicore Chips Much Faster

New research from MIT describes a system that cleverly distributes data around multicore chips’ memory banks, improving execution times by 18 percent on average while actually increasing energy efficiency. Computer chips’ clocks have stopped getting faster. To keep delivering performance improvements, chipmakers are instead giving chips more processing units, or cores, which can execute computations […]
