Marine scientists’ letter in the journal Science urges preservation of one of the last coral refuges from climate change An international group of marine scientists led by Karine Kleinhaus, of Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS), has published a letter in Science that is a call to action for policy makers, government agencies and ocean conservation groups to take major steps to preserve Egypt’s 1800 km of coral reefs– a massive section of the Red Sea’s reef system. Egypt’s reefs generate billions of dollars annually from tourism and tourism-related commerce. The reefs of the northern Red Sea are especially valuable as they constitute one of the world’s few marine refuges from climate change. Almost the entire western coastline of this ref...

New genetic analysis of ancient Africans creates a clearer picture Ancient DNA from the remains of nearly three dozen African foragers—groups associated with hunting, gathering, and fishing—sheds new light on how groups across sub-Saharan Africa lived, traveled and settled prior to the spread of herding and farming. The study involved an international team of 44 researchers including experts from Stony Brook University. The findings, to be published in Nature, produced the earliest DNA of humans on the continent, at some 5,000 to 18,000 years old. The new genetic findings add weight to archaeological, skeletal and linguistic evidence for changes in how people were moving and interacting across Africa toward the end of the Ice Ages. Around 50,000 years ago, distinct groups of forager...
