These are just some examples of how easy it is to break the leading pattern-recognition technology in AI, known as deep neural networks (DNNs). These have proved incredibly successful at correctly classifying all kinds of input, including images, speech and data on consumer preferences. They are part of daily life, running everything from automated telephone systems to user recommendations on the streaming service Netflix. Yet making alterations to inputs — in the form of tiny changes that are typically imperceptible to humans — can flummox the best neural networks around.

Artificial-intelligence researchers are trying to fix the flaws of neural networks.

Positrons traverse two circular 2-mm-wide collimators 10.2 cm apart. The interferometer is composed of two SiN diffraction gratings with periodicity d1 and d2, respectively, separated by L1 = (118.1 ± 0.2) mm. Interference fringes with d3 periodicity are expected at L2 = (576 ± 5) mm. The emulsion is tilted so that the Y axis in the reference frame of the emulsion surface (X, Y) forms a 45° angle with the y axis of the laboratory. Gamma rays (511 keV) from positron annihilation in the emulsion are monitored with a high-purity germanium (HpGe) detector for rate measurement.

Recently, an 82-year-old woman who suffered from dementia, who couldn’t recognize her own son has miraculously got her memory back after changing her diet.

When his mother’s condition became so severe that for her own safety she had to be kept in the hospital, Mark Hatzer almost came to terms with losing another parent.

Could be redirected with lasers.

NASA needs “more hands on deck” due to one asteroid threat in particular, claimed scientist Professor Greg Leonard, who works for the US space agency.

Star Trek’s Montgomery Scott famously said “ye cannot change the laws of physics”, but a real-life space engineer says he might have just done that.

David Burns of NASA’s Marshall Space Flight Center in Alabama has unveiled what he’s calling the ‘helical engine’, which could potentially power flights across space without using any fuel at all.

There’s just one small problem — it breaks the laws of physics as we know them.

New technology plans to tackle the future energy crisis by capturing sunlight and turning it to bioenergy.

Ariel Rubinstein, who says economics lacks common sense, heads list of likely winners.

Researchers have developed a new treatment method capable of detecting Lyme disease in just 15 minutes.

Caused by Borrelia burgdorferi and transmitted by the bite of infected Ixodes ticks, Lyme disease if left untreated can cause serious neurologic, cardiac, and/or rheumatologic complications.

“Our findings are the first to demonstrate that Lyme disease diagnosis can be carried out in a microfluidic format that can provide rapid quantitative results,” said Sam Sia, professor of biomedical engineering at Columbia Engineering.

Just when you thought one of the most bizarre things in space was something that eats massive amounts of light and energy and would probably shred you with its gravitational forces, what if it was something even harder to imagine?

Black holes are supposed to have a singularity—a point that is so small and dense we can’t even fathom it—in the middle of all that swirling light and gas. But what if at least some cosmic phenomena that look like black holes are actually cosmic objects full of dark energy? That is what astrophysicists Kevin Croker and Joel Weiner of the University of Hawai’i at Manoa recently published in a study in The Astrophysical Journal that tries to prove these hypothetical Generic Objects of Dark Energy (GEODEs) exist.
