Caseids are "mammal-like" reptiles that lived about 300-250 million years ago. They had a barrel-shaped trunk, but scientists have struggled to realize how these reptiles breathed. New calculations have revealed some surprising information that suggests that these animals may have used a diaphragm much like those humans have today.
A group of scientists has completed research into radioactively contaminated material to gain further understanding around the issue, crucial for the safe and more efficient completion of future decommissioning projects.
For more than four decades, cholera has recurred in Cameroon, affecting tens of thousands of people a year. Most recently, the West African country was one of four that had a death rate of more than five percent from the bacterial disease, exceeding the World Health Organization's target of less than one percent. Now, researchers have discovered one reason Cameroon has struggled to control the disease. Cholera follows different, distinct outbreak patterns in different climate subzones of the large country, researchers report.
Researchers test mechanisms explaining differences in dengue serotype and disease severity by statistically fitting mathematical models to viral load data from dengue-infected individuals. They find a role for viral replication in explaining serotype-specific differences in viral load -- according to a new study.
