Your Wi-Fi Can Be Hacked Due to WPA2 Protocol Vulnerability Called KRACK

The group of cybersecurity experts has recently found the greatest and unprecedented vulnerability in the security of Wi-Fi networks. The most popular security protocol for WI-FI networks – the WPA2 protocol appears to be the weak link. Image credit: Christiaan Colen via Flickr, CC BY-SA 2.0 What is KRACK? New vulnerability called KRACK allows hackers to intercept and steal passwords, ...

Despite odds, fish species that bypasses sexual reproduction is thriving

The very rare animals that reproduce asexually — only about one in 1,000 of all living vertebrate species — are thought to be at an evolutionary disadvantage compared with their sexually reproduced counterparts. But that theory doesn’t hold true regarding the Amazon molly, an all-female fish species that has thrived for millennia in the fresh waters along the Mexico-Texas border. ...

Astronomers’ Dark Energy Hopes Fade to Gray

If so, as the universe grows, it will expand faster and faster and run away from itself. Eventually other galaxies would be flying away so fast that we couldn’t see them. The universe would become dark and cold. The cosmologist Lawrence Krauss of Arizona State once described this as “the worst possible universe.” Continue reading the main story If on ...

Noise sensitive persons can blame their brain

Too loud! Image credit: JMEG via Flickr, CC BY 2.0 Up to 20-40% of the healthy population are sensitive to noise according to different estimates, which make them less tolerant to background noise. A new study, recently published in the scientific journal NeuroImage, shows that noise sensitivity can be measured physiologically in the brain. Brain scans have shown that both ...

Animals Are Losing Their Vagility, or Ability to Roam Freely

But a new and growing field called “movement ecology” is casting light on the secretive movements of wildlife and how those habits are changing. A global study of 57 species of mammals, published in the journal Science, has found that wildlife move far less in landscapes that have been altered by humans, a finding that could have implications for a ...

Motion Capture-like Technology for Tracking Protein Shape

In many modern animated movies, the trick to achieving realistic movements for individual characters and objects lies in motion-capture technology. This process often involves someone wearing a tracking suit covered in small, colored balls while a camera captures the position of those colored balls, which is then used to represent how the person is moving. Researchers at the University of ...

Particulate filter research may enable more fuel-efficient vehicles

Researchers are looking to neutrons for new ways to save fuel during the operation of filters that clean the soot, or carbon and ash-based particulate matter, emitted by vehicles. A team of researchers from the Energy and Transportation Science Division at the Department of Energy’s Oak Ridge National Laboratory is studying soot and ash collection and removal in particulate filters ...
