An Artificial Womb Successfully Grew Baby Sheep -- and Humans Could Be Next (theverge.com) 177

An anonymous reader quotes a report from The Verge: Inside what look like oversized ziplock bags strewn with tubes of blood and fluid, eight fetal lambs continued to develop -- much like they would have inside their mothers. Over four weeks, their lungs and brains grew, they sprouted wool, opened their eyes, wriggled around, and learned to swallow, according to a new study that takes the first step toward an artificial womb. One day, this device could help to bring premature human babies to term outside the uterus -- but right now, it has only been tested on sheep. The Biobag may not look much like a womb, but it contains the same key parts: a clear plastic bag that encloses the fetal lamb and protects it from the outside world, like the uterus would; an electrolyte solution that bathes the lamb similarly to the amniotic fluid in the uterus; and a way for the fetus to circulate its blood and exchange carbon dioxide for oxygen. Flake and his colleagues published their results today in the journal Nature Communications.

New Air-Gap Jumper Covertly Transmits Data in Hard-Drive Sounds (arstechnica.com) 83

Security researchers have found a new way to siphon data out of an infected computer even when it has been physically disconnected from the Internet -- otherwise known as "air-gap" computers -- to prevent the leakage of sensitive information it stores, reports ArsTechnica. From the article: The method has been dubbed "DiskFiltration" by its creators because it uses acoustic signals emitted from the hard drive of the air-gapped computer being targeted. It works by manipulating the movements of the hard drive's actuator, which is the mechanical arm that accesses specific parts of a disk platter so heads attached to the actuator can read or write data. By using so-called seek operations that move the actuator in very specific ways, it can generate sounds that transfer passwords, cryptographic keys, and other sensitive data stored on the computer to a nearby microphone. The technique has a range of six feet and a speed of 180 bits per minute, fast enough to steal a 4,096-bit key in about 25 minutes.

Facebook Rolls Out Code To Nullify Adblock Plus' Workaround (techcrunch.com) 426

An anonymous reader writes: The Wall Street Journal issued a report Tuesday that said Facebook will begin forcing ads to appear for all users of its desktop site, even if they use ad-blocking software. Adblock Plus, the most popular ad-blocking software, opposed Facebook's plan and found a workaround to Facebook's revision two days later. Now, TechCrunch is reporting that Facebook is well aware of Adblock Plus' workaround and their "plan to address the issue" is coming quick. "A source close to Facebook tells [TechCrunch] that today possibly within hours, the company will push an update to its site's code that will nullify Adblock Plus' workaround," reports TechCrunch. "Apparently it took two days for Adblock Plus to come up with the workaround, and only a fraction of that time for Facebook to disable it." An update on their site says, "A source says Facebook is now rolling out the code update that will disable Adblock Plus' workaround. It should reach all users soon."
