Tips to avoiding blood clots and improving blood storage for transfusions

Hibernating mammals are amazing! How in the world do they prevent blood clots when they not only reduce their body temperature but also their blood flow during hibernation? That question is precisely what a new study published in Physiological Genomics examined.   Typically, cold temperatures are known to activate the process of blood clotting by stimulating platelets. Platelets are sticky cells without a nucleus that circulate in the blood. When […]

Secrets to rockfish longevity revealed

Rockfish have gained the attention of scientists due to their exceptional longevity. Researchers at the University of California, Berkeley sequenced the complete genome of 88 species of rockfish in the Pacific Ocean to try to find clues that could explain their longevity. While some are rather short-lived (ex: calico rockfish, Sebastes dallii, only live around 10 years), longer-lived species, like rougheye rockfish (Sebastes aleutianus), can live to be over 200 […]

Scientists get a glimpse of what makes cephalopods so smart

From walking on land, to solving complex problems, cephalopods continue to amaze us with their intelligence and nervous system development. In a new study published in Current Biology, Dr. Wen-Sung Chung from the University of Queensland Brain Institute and colleagues decided to take a closer look at what makes their brains unique using MRI imaging. Compared to other invertebrates, cephalopods are rather brainy. In fact, some cephalopods have over 500 […]

Surviving environmental challenges

Red tides happen when dinoflagellate algae populations increase and turn the water a shade of red due their red pigments. These algae consume oxygen in the water and release carbon dioxide and other acidic products that make the surrounding water acidic and hypoxic. These events are becoming more common with climate change. In fact, the most recent event off the coast of Sothern California occurred in 2020 and resulted in […]
