The real-life tricorder: Scientists create device that can measure all of the vital signs in just TEN seconds
The £100 Scanadu Scout can measure heart rate, temperature, blood pressure, blood oxygen levels, respiratory rate, ECG and emotional stress. It takes the readings when held to the forehead and then uses Bluetooth to send them to a smartphone app (top left), much like the Star Trek tricorder (bottom right).
GADGET REVIEWS
SMARTPHONES? IT'S YOUR CALL
The ultimate non-iPhone smartphone guide...
Talk time: 9.5hr (7hr playback, 55hr music)
Spec: 3.7in (800x480 pixels) AMOLED screen, 16GB, 1.4GHz Windows Mango, 8MP camera, 720p HD video
Verdict: This combination works wonderfully. It's a pleasure to use and Nokia's Drive GPS app is impressive. We've rated these iPhone alternatives from Ace down to Five - and the Nokia is at the head of the pack.
Talk time: 8.5hr
Spec: Android Ice Cream Sandwich OS, 1.2GHz dual-core processor, 4.65in (720x1,280) AMOLED screen, 5MP camera, 1080p video, 16GB memory
Verdict: It's got a beautiful screen, intuitive operating system and cool features like face-recognition security, but battery life doesn't quite match the hype.
Talk time: 6hr 50min
Spec: Windows Phone 7.5 Mango, 1.5GHz, 4.7in (480x800) screen, 16GB, 8MP camera, 720p HD video
Verdict: The Titan is slim, light and has the largest screen on any Windows device. Shame they didn't give it better screen resolution.
Talk time: 4hr
Spec: Android 2.3 Gingerbread, 1 GHz, 4.3in (800x480) screen, 8MP camera, 1080p HD video, 8GB memory
Verdict: The sharp lines and thin bezel give a professional look while the monochrome interface screams class. One for the fashionistas.
Talk time: 5hr 20min
Spec: BlackBerry 7 OS, 1 GHz, 2.45in (480x360) screen, 5MP camera, VGA video, 8GB memory
Verdict: Beautifully made and with a battery life most handsets would kill for, but the OS is limiting and even with its touch screen it can't compete.
Talk time: 7hr 35min
Spec: Android 2.3.4 Gingerbread, 1.4GHz, 4.2in (854x480) screen, 1GB internal, 8GB MicroSD memory (included), 8.1MP camera, 720p HD video
Verdict: Motorola take note, this is how you do slim and sexy. The camera is let down by a poor menu and awful shutter button, but Sony's social media widget 'Timescale' is a time-saving stroke of genius.
Talk time: 10hr
Spec: Android 2.3.5 Gingerbread, dual-core 1.2 GHz processor, 4.3in Super AMOLED (540x960) screen, 8MP camera, Full HD video, 16GB
Verdict: Light and impossibly thin, but even with its rigid Kevlar frame it feels limp and lopsided in the hand. Shame, as the screen is exceptional and the interface is bursting with neat tricks including the ability to resize the icons you use most.
Talk time: 4hr 30min
Spec: Android 2.3 Gingerbread, 800MHz processor, 3.5in (800x480) screen, 5MP camera, 512 MB internal memory, 2GB microSD card (included)
Verdict: Never going to induce envy but if you want smartphone functionality without budget busting it's hard to fault. Navigation is intuitive; battery life excellent.
Talk time: 4hr
Spec: Android 2.3 Gingerbread OS, 3.5in (800x480) screen, 5MP camera, 800MHz processor, 512MB memory, 2GB microUSB card, GPS
Verdict: The Vivacity is essentially the San Francisco II with iPhone looks, and while it lacks the fluidity of its more expensive cousins, you can get app-happy on a budget.
Talk time: 4hr 30min
Spec: Android 2.2 Froyo, 2.8in (240x320) screen, 2MP camera, 130MB memory, 2GB microSD card
Verdict: It might be cheap, small and pocketable but as a smartphone it's cramped, slow and the minuscule memory limits the number of apps.

British photographers Fiona Rogers and Anup Shah captured apes in Indonesia and Borneo - and highlighted how human our evolutionary cousins are.
The many faces of Google Earth: Global scan for human-looking features begins
German researchers have developed a computer system created in openFrameworks - a creative coding program - that can scan Google Earth satellite images looking for faces. The scanner searches the entire world, switches to the next zoom level and starts again, taking snapshots and co-ordinates of all the 'faces' it finds. Onformative admit that not all the so-called faces are recognisable and these are dismissed.
