The team also worked with flies genetically engineered so light could switch their olfactory neurons on directly, in both antennae at once. When scientists swapped real odor for a beam of 660-nanometer red light, the insects tracked the edge of this light plume flawlessly. The real surprise, though, came when the team took a close look at what the flies were doing when there was no smell at all to guide them. Olfactory memories When the researchers made a plume vanish while a fly was outside it, the insect kept heading back to where the edge should have been. Rather…

Investing.com — Goldman Sachs said its long/short Momentum factor recently hit its highest volatility in decades outside of a recession, matching the historical pattern that follows three-month rallies of 20% or more, as sharp deleveraging among hedge funds and exchange-traded fund holders points to diminishing rotational turbulence in coming weeks.

The chip also uses resistive RAM, or RRAM, a type of nonvolatile memory that Huang says is designed to make physical extraction of stored data more difficult than conventional flash memory. With flash memory, he says, “if you de-layer it down to the actual flash cells … you can just see the ones and zeros literally on these chips.” Huang is cautious, however, about overhyping the chip’s security capabilities. He estimates that it could withstand attacks involving tens of thousands of dollars in resources, but says an adversary with millions of dollars and a sophisticated hardware-analysis lab could likely defeat…

Choi asked again on August 19. No document arrived. In September, the Honor Committee sent out its “official notification letter” telling Rignol that he was accused of “improperly utiliz[ing] AI on the final exam in [his] course.” The committee wanted to meet in October; Rignol told them he was getting married in Europe and asked to postpone. The request was granted. In early November, just days before the hearing, Rignol was back from Europe and arguing about the committee’s composition. He said that its student members should be recused unless they had worked through the same courses and problem sets…
