The Ocean’s ‘Biological Pump’ Captures More Carbon Than Expected
Fig 1. Carbon loss traditional measurement at 150 meters compared to carbon loss measurement considering depth of sunlight penetration. Every spring in the Northern Hemisphere, the ocean surface erupts in a massive bloom of phytoplankton. Like plants, these single-celled floating organisms use photosynthesis to turn light into energy, consuming carbon dioxide and releasing oxygen…

Viruses don’t have a metabolism; but some have the building blocks for one
Fig 1 . ‘Brown tide virus’ is a member of a class called the giant viruses. Researchers have discovered genes for key cellular metabolic cycles in many giant viruses, suggesting that these microbes may be interacting with their hosts in more diverse ways than previously thought. In satellite photos of the Earth, clouds of…

New Qualcomm chips pack high-end features for lower-cost earbuds
Qualcomm is getting ready to usher in a new generation of super low-power Bluetooth earbud chips. The QCC514X and the QCC304X will support Qualcomm’s TrueWireless Mirroring technology. This means that wireless connectivity is secured with a single earbud that is paired with another. When the user removes the primary earbud, the other mirroring bud takes…

New metabolism discovered in bacteria
Fig 1. While acetic acid creating bacteria and methanogens are dependent on the transfer of hydrogen in anoxic biotopes, Acetobacterium woodii recycles hydrogen within its cell. They make sauerkraut sour, turn milk into yogurt and cheese, and give rye bread its intensive flavour: bacteria that ferment nutrients instead of using oxygen to extract their energy.…
