Biometric authentication could soon be revolutionized as scientists in Japan have developed a security tool which identifies people by their breath. Being able to fully rely on identity check systems is more crucial than ever for public institutions such as airports but also a wide variety of private companies. Researchers from Kyushu University said their olfactory sensor had an accuracy of 97 percent in a first series of tests. Chaiyanut Jirayupat from Kyushu University's Institute for Materials Chemistry and Engineering is the first author of the study. Speaking about the potential advantages compared to security checks of fingerprints, voices or…

After previewing the feature in beta last April, WhatsApp is rolling out greater privacy controls for Profile Photo, About, Status and Last Seen settings, the company tweeted. Until now, you could only block those settings for Everyone, My Contacts or Nobody, but the new update introduces a "My Contacts Except" option that offers far more granular control.

The role of carbon dioxide in heating up the planet is well acknowledged. While countries are making efforts to curb their carbon emissions, there is also the need to trap carbon dioxide that is currently being released to ensure that the planet's temperature increases remain under control. To achieve this, many are looking to capture carbon directly from the atmosphere and store it. However,…
