Sleepy fruitflies get mellow

Science Daily - Tue, 28/07/2015 - 8:24pm
Whether you're a human, a mouse, or even a fruitfly, losing sleep is a bad thing, leading to physiological effects and behavioral changes. Researchers used fruitflies to probe deeper into the cellular and molecular mechanisms that govern aggression and sleep and found that sleep deprivation reduces aggression in fruitflies and affects their reproductive fitness. They identified a related molecular pathway that might govern recovery of normal aggressive behaviors.

Past and present sea levels in the Chesapeake Bay Region, USA

Science Daily - Tue, 28/07/2015 - 8:24pm
Scientists write that sea-level rise (3.4 mm/yr) is faster in the Chesapeake Bay region than any other location on the Atlantic coast of North America, and twice the global average (1.7 mm/yr). They have found that dated interglacial deposits suggest that relative sea levels in the Chesapeake Bay region deviate from global trends over a range of timescales.

Veteran IT Journalist Worries That Online Privacy May Not Exist (Video)

Slashdot - Tue, 28/07/2015 - 8:17pm
Tom Henderson is a long-time observer of the IT scene, complete with scowl and grey goatee. And cynicism. Tom is a world-class cynic, no doubt about it. Why? Cover enterprise IT security and other computing topics long enough for big-time industry publications like ITWorld and its IDG brethren, and you too may start to think that no matter what you do, your systems will always have (virtual) welcome mats in front of them, inviting crackers to come in and have a high old time with your data. Note: Alert readers have probably noticed that we talked with Tom about cloud security back in March. Another good interview, worth seeing (or reading).

Intel and Micron Unveil 3D XPoint Memory, 1000x Speed and Endurance Over Flash

Slashdot - Tue, 28/07/2015 - 7:37pm
MojoKid writes: Today at a press conference in San Francisco, Intel and Micron unveiled 3D XPoint (Cross Point) memory technology, a non-volatile memory architecture they claim could change the landscape of consumer electronics and computer architectures for years to come. Intel and Micron say 3D XPoint memory is 1000 times faster than NAND, boasts 1000x the endurance of NAND, and offers 8-10 times the density of conventional memory. 3D XPoint isn't electron based, it's material based. The companies aren't diving into specifics yet surrounding the materials used in 3D XPoint, but the physics are fundamentally different than what we're used to. It's 3D stackable and its cross point connect structure allows for dense packing and individual access at the cell level from the top or bottom of a memory array. Better still, Intel alluded to 3D XPoint not being as cost-prohibitive as you might expect. Intel's Rob Crooke explained, "You could put the cost somewhere between NAND and DRAM." Products with the new memory are expected to arrive in 2016 and the joint venture is in production with wafers now.
