Transformative change can save humans and nature - Center for Systems Integration and Sustainability
International sustainability experts, including MSU's Jianguo "Jack" Liu, outline what's needed how the human/nature balance must change.
Dogs may be able to count, suggests a new fMRI brain scan study, which found that when dogs compute basic numbers, a specific part of the brain activated, and it’s the same part that humans use to do their own basic counting. The ability to process basic number quantities is spontaneous.

Scientists discover dogs can do math, too
Dogs and humans appear to use the same brain area to compute basic numbers.
Using human blood cells, researchers successfully 3D bioprinted “mini-livers” that perform all liver’s typical functions (producing vital proteins, storing vitamins, and secreting bile). Liver tissue can be made in the lab in only 90 days and may in future become an alternative to organ transplants.

Scientists present an approach to encode medical history on a patient using quantum dots in the skin, which are invisible to the naked eye yet detectable when exposed to near-infrared light, with success on rats and synthetic human skin. This may lead to decentralized data storage and biosensing.

Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination
Vaccines prevent disease and save lives; however, lack of standardized immunization recordkeeping makes it challenging to track vaccine coverage across the world. McHugh et al. developed dissolvable microneedles that deliver patterns of near-infrared light…
