SINGING GLOVES: Researchers at the University of British Columbia in Canada have created a pair of gloves that cause a computer to produce human-like vocalisations. The right-hand glove contains motion sensors that let an open hand create vowels while a closed hand creates consonants. Meanwhile 3D position sensors on the same glove affect pitch. A foot pedal controls volume. The left-hand glove has buttons to activate consonants such as p or b that need a sudden release of pressure. The gloves were designed as a voice synthesiser for people with disabilities, but they're also being explored as a musical instrument - a wearer could sing a duet with herself. The duets are rather odd. New Scientist has more. QUAKE STUDIES: Chinese scientists believe the air guns used to help find oil can be also used to study and predict earthquakes. In oil exploration, the air guns shoot sharp blasts of pressurised air that generate seismic vibrations. Geologists can then map the structure of rock deposits or other features. The Chinese studies use air guns to deliberately generate consistent seismic waves rather than just waiting till they occur naturally. SKI SPIKES: Snowshoes need a toe hole and spikes so you can walk uphill. But it would be easier to glide down slopes than walk and the spikes don't help. The Hive hybrid snowshoe cleverly lets you both walk and glide. A hinged flap with spikes folds up into the toe hole leaving a smooth surface on the bottom. The bindings also move to a locked gliding position. Climb up; glide down. It looks fun. Dare to visit the Hive. Click here to see the video. TAKE A NUMBER: Norway is about to start using genome sequencing of cancer tumours in an effort to improve its national healthcare service. Similar schemes in other countries use conventional genetic testing but Norway's plan is to sequence DNA. This could allow doctors to identify the best drugs to treat specific tumours. The DNA sequencing approach is becoming possible because the cost of the technique has plummeted recently. Better diagnosis, better treatment - it's a win all round. Get into Nature. LISTEN TO THE BEAT: Scientists and engineers at Oregon State University and the University of California have created a tiny electronic device that monitors a person's heart rate, respiration, movement and similar vital signs. It doesn't need to be in direct contact with the skin either, and the battery lasts for a week without recharging. Data from the device can be downloaded by doctors and others to assess a patient's well-being. The researchers aim to make the device even smaller and cheaper so it could be widely used. But will it tweet the data? Learn more at Oregon State University.
