The largest "tree of life" ever created has been released, spanning 3.5 billion years and 2.3 million species. The work was not carried out from scratch, as such an effort would consume a vast amount of man-hours. Instead the researchers compiled data from almost 500 existing smaller trees displaying the divergence and evolution of life as we understand it.
While there are no shortage of ways to shoot in 3D, these typically
involve devices which are more bulky, complex, and expensive than
traditional digital cameras. However, a team of engineers has discovered
a way to unlock the previously unrecognized 3D imaging capability of
ordinary digital camera technology, by repurposing existing components.
An international study
appears to have created a test that can determine the biological age
of a patient's body. The research – undertaken by King's College
London (KCL), the Karolinska Institutet in Sweden, and Duke University
in the US – could have a broad range of applications, including
improving screening techniques for age-related diseases such as
Alzheimer's, allowing doctors to begin treatment earlier in the
Although the ability tends to wane as we get older, the human auditory system is pretty good at filtering out background noise and making a single voice able to be understood above the general hubbub of a crowded room. But electronic devices, such as smartphones, aren't quite as gifted, which is why getting Siri or Google Now to understand you in crowded environments can be an exercise in futility. But now researchers have developed a prototype sensor that’s not only able to figure out the direction of a particular sound, but can also extract it from background noise.
If the thought of using a person's brainwaves to control a machine isn't quite enough to make the mind boggle, then mixing signals from multiple brains for the same purpose might just do the job. This far-fetched field of neuroscience is edging ever closer to real-world technology, with a number of recent research efforts achieving significant advances, with mind-controlled drone flight just one example. The latest step forward in this area sees the brains of separate animals hooked up and their combined motor and sensory information used for things like controlling a virtual arm, pattern recognition and even predicting the weather.
The rise of cloud gaming services such as PlayStation Now may have ushered in a new era of convenience for blasting virtual aliens and monsters to smithereens, but on-demand play brings with it one huge unwanted drawback: the bandwidth required is astronomical. But researchers at Duke University and Microsoft Research think they have a solution that'll let gamers have their on-demand cake and eat it too. They have developed a tool called Kahawai (Hawaiian for stream), which splits the rendering calculations between your device and a remote server rather than offloading them all to the server.
