Coral reefs could feed millions if we let them rebuild
The world is now home to about 8.3 billion people, and millions still do not have enough nutritious food. As concerns about food security grow, scientists are looking beyond land for solutions. New research suggests the ocean could play a much…

Bacteria reveal second 'shutdown mode' for surviving antibiotic treatment
A new study reveals that bacteria can survive antibiotic treatment through two fundamentally different “shutdown modes,” not just the classic idea of dormancy. The paper is published in the journal Science Advances.

Flowering plant origins: Dosage-sensitive genes suggest no whole-genome duplications in ancestral angiosperm
Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution have long been a central question in plant evolutionary biology. Whole-genome duplication (WGD), or polyploidization, is…

Evidence of upright walking found in 7-million-year-old Sahelanthropus fossils
In recent decades, scientists have debated whether a seven-million-year-old fossil was bipedal—a trait that would make it the oldest human ancestor. A new analysis by a team of anthropologists offers powerful evidence that Sahelanthropus…

How the 'guardian of the genome' impacts blood vessel growth
The protein p53, best known as the “guardian of the genome” for its role in preventing cancer, can affect blood vessels in different ways. However, it has not been clear how p53 can slow blood vessel growth in some cases and damage blood vessels…

Two white-blooded fish, two paths: Icefish and noodlefish independently lose red blood cell function
Antarctic icefish are famous for living without red blood cells, but they are not alone. A species of needle-shaped, warm-water fish called the Asian noodlefish also lacks hemoglobin and red blood cells. Like icefish, its veins are filled with…
