Sperm sensor molecule could lead to new contraceptives or fertility treatments

The story of sperm meets egg sounds pretty simple, but there are a lot of factors driving that all-important meeting. Now, researchers at Yale University have identified a key molecule that helps activate sperm and guide them to the egg. This could make it a target for both infertility treatments and new contraceptive methods.

Artificial embryos possible after embryonic stem cells breakthrough

An incredible new study from researchers at the Hebrew University of Jerusalem has for the first time found a way to transform skin cells into all three of the stem cell types that make up an early-stage embryo. This extraordinary discovery points a way toward creating an embryo without the need for an egg or sperm.

How food dye may have unlocked 3D printable organs for transplant

Currently, if you need a replacement organ you'll have to join a long waiting list or have a donor ready and willing. An emerging alternative is to 3D print new organs out of a patient's own cells, but that technology is still going through some teething issues. Now researchers have found a surprisingly simple answer to the complex problem of printing detailed vascular networks, and shown it off with a dramatic model of a breathing lung that passes oxygen into surrounding blood vessels.

Master & Dynamic’s first noise-canceling headphones are the featherlight MW65s

Master & Dynamic is one part fashion brand, one part headphones manufacturer. It’s a company that usually champions the premium over the practical, however its latest pair of headphones tries to deliver both. The new Master & Dynamic MW65 over-ear cans have active noise canceling, up to 24 hours of battery life with USB-C fast charging, and a weight of just 250g / 8.8oz. That’s a sliver lighter than Sony’s 1000X M3s, and it’s doubly impressive since M&D is doing it while using substantial chunks of metal and leather instead of Sony’s more pragmatic all-plastic construction. Alas, the MW65s also cost an impressive $499, far higher than Sony’s sensible $349.

I’ve had a pair of pre-production MW65s in for testing the past couple of weeks,...

Microsoft is going to ship a full Linux kernel in Windows 10

Microsoft has surprised many in the Linux developer community in recent years. Surprises have included bringing things like the Bash shell to Windows, or native OpenSSH in Windows 10, and even including Ubuntu, SUSE Linux, and Fedora in the Windows Store. Microsoft is now going even further, with plans to ship a full Linux kernel directly in Windows 10.

“Beginning with Windows Insiders builds this Summer, we will include an in-house custom-built Linux kernel to underpin the newest version of the Windows Subsystem for Linux (WSL),” explains Microsoft program manager Jack Hammons. “The kernel itself will initially be based on version 4.19, the latest long-term stable release of Linux. The kernel will be rebased at the designation of new...

Watch Microsoft’s failed HoloLens 2 Apollo moon landing demo

Microsoft opened its Build developer conference in Seattle this morning with an awkward start. The software giant was supposed to show a recreation of the Apollo moon landing with its HoloLens 2 headsets. Instead, the demo failed, a nightmare scenario for anyone running a live show. “Well, it seems doing a live demo is actually harder than landing on the moon,” said A Man on the Moon author Andrew Chaikin. “Thank you for your time,” said Chaikin, before exiting the stage and leaving the audience confused at a failed demo.

A minute or so passed, and then Microsoft CEO Satya Nadella appeared on stage, with no acknowledgment of the failed demo or what the company was trying to achieve. If the demo had actually worked, the result was...

Zhang Yimou’s action-fantasy Shadow sets gorgeous action in a morally gray world

Filmmakers often define their movies by making distinctive visual choices. Whether it’s Victor Fleming signaling The Wizard of Oz’s shift from Kansas to Oz by introducing bold Technicolor, or Zack Snyder reinventing the ancient world on a digital soundstage with 300, some films stand out because they introduce cinematic worlds that don’t look like anything that’s come before.

Add to that list Zhang Yimou’s Shadow, a historical fantasy-drama that reimagines the palace intrigue of China’s Three Kingdoms era as an almost entirely black-and-white world, where the swirl of the two colors reflects the moral grayness of the people who inhabit it. Zhang creates the look not by shooting in black and white, but by using sets and costumes drained...
