—Artificial Skin Transmits Signals To Neurons “Materials Science: Interfacing pressure sensors and organic circuits with nerve cells could give prosthetics a sense of touch” Prosthetic limbs can restore an amputee’s ability to walk or grip objects, but they haven’t yet been able to restore a person’s sense of touch.

—Atom-sized bits debut in simple circuits “Silicon dangling bonds can serve as building blocks for digital electronics” In the ongoing drive to make circuitry ever smaller and more powerful, researchers have devised a method for turning individual silicon atoms into electronic bits and have used the method to make digital components known as logic gates (Nat.

Some observers wonder if Platform can keep up its hectic acquisition pace, maintain its credit rating, and integrate the operations it has acquired without losing business discipline. Alent will augment two earlier Platform acquisitions in electronics and related materials: MacDermid, which was its first deal in October 2013, and OM Group’s electronic materials and photomasks operations, which it is currently buying.

Court of Appeals for the Federal Circuit that invalidated several of Teva’s patents on Copaxone. Had it been upheld, the appeals court ruling would have given generic competitors a green light to enter the market. Teva argued to the high court that the Federal Circuit should not have second-guessed factual findings made earlier by a trial court that upheld the validity of Teva’s patents.

He and his colleagues pioneered the development of integrated circuit technology at Fairchild, as well as the first microprocessor at Intel, where Moore is now chairman emeritus. The rest is history. Intel's computer chips now drive 80% of the world's computers, and semiconductor technology is the foundation for much of what we hold essential in modern life.

—Kinase’s Oscillatory Behavior Controls Cell Signaling “Protein kinase A forms an oscillatory signaling circuit that represents a new mechanism of signal transmission in cells” A key protein kinase enzyme participates in unusual oscillatory behavior that represents a new mechanism of signal transmission in cells. Andre Levchenko, Jin Zhang, and coworkers at Johns Hopkins University School of Medicine monitored signaling activity with fluorescence and used mechanistic modeling to show that protein kinase A, which helps regulate insulin secretion, calcium influx, and other important cellular processes, forms an oscillatory signaling circuit with cyclic adenosine monophosphate and Ca2+ in insulin-secreting cells (Nat.

Tang, a professor in the electrical and mechanical engineering departments at Yale University, and colleagues have been able to build an integrated nano-optical circuit and use the circuit's optical gradient force to vibrate a bridge of silicon about 10 ??m long and 500 nm wide, in the nano-optical circuit (Nature 2008, 456, 480).
