Diaphragm much older than expected

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.

Breakthrough offers greater understanding of safe radioactive waste disposal

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.

Cameroon’s cholera outbreaks vary by climate region

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.

Dengue strains differ in rates of viral replication

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.

USGS estimates 20 billion barrels of oil in Texas’ Wolfcamp Shale Formation

The Wolfcamp shale in the Midland Basin portion of Texas' Permian Basin province contains an estimated mean of 20 billion barrels of oil, 16 trillion cubic feet of associated natural gas, and 1.6 billion barrels of natural gas liquids, according to an assessment by the U.S. Geological Survey. This estimate is for continuous (unconventional) oil, and consists of undiscovered, technically recoverable resources.

Tooth wear patterns suggest Paranthropus early hominins had softer diets than expected

Analysis of wear patterns on fossil teeth from East African hominins suggests the diets of Paranthropus aethiopicus and Paranthropus boisei were softer than had been thought, according to a study.

Taking miniature organs from lab to clinic

Scientists have developed a gel for growing miniaturized body organs that can be used in clinical diagnostics and drug development. Organoids are miniature organs that can be grown in the lab from a person's stem cells. They can be used to model diseases, and in the future could be used to test drugs or even replace damaged tissue in patients.

Climate change may prevent volcanoes from cooling the planet

New research shows that climate change may impede the cooling effect of volcanic eruptions. Previous research has shown that as the planet warms, the lower layers of the atmosphere will expand, making it much harder for the gasses to reach the stratosphere.
