Biohybrid battery harvests energy from electric bacteria

Some bacteria are known to produce their own electricity, which could make them useful in batteries and fuel cells. But so far, attempts have been inefficient and inflexible. Now, researchers at Karlsruhe Institute of Technology (KIT) have created a “b… Continue reading Biohybrid battery harvests energy from electric bacteria

Study shows why trees won’t benefit much from extra CO2 in the air

The amount of carbon dioxide in the atmosphere is increasing steadily, having recently reached the highest concentration in human history. While that’s undoubtedly bad news for the planet, one argued silver lining is that plants are better off due to m… Continue reading Study shows why trees won’t benefit much from extra CO2 in the air

Dynamic, reprogrammable material goes hard under light and soft in the dark

Materials that change their properties in response to different environmental triggers promise all kinds of versatility for all kinds of applications, and an international team of scientists has just come up with a particularly inventive one…. Continue reading Dynamic, reprogrammable material goes hard under light and soft in the dark

Carbon dioxide could be converted into graphene

Carbon dioxide is kind of painted as the villain of the 21st century, and it’s not enough to just reduce our emissions now – we need to remove some of what’s already in the atmosphere. Now, researchers at Karlsruhe Institute of Technology (KI… Continue reading Carbon dioxide could be converted into graphene

GPG Patches 18-Year-Old Libgcrypt RNG Bug

New versions of GPG and its crypto library Libgcrypt were released on Wednesday addressing a vulnerability that could allow an attacker to predict Libgcrypt RNG output. Continue reading GPG Patches 18-Year-Old Libgcrypt RNG Bug
