What are researchers doing? The sixth mass extinction continues and is even accelerating, but conservation scientists, it is claimed, have no solutions to offer. Even more worrying, the researchers would be so pessimistic that the warnings they give could be counterproductive. But is this really the case? Two CNRS researchers* …

A new scientific analysis of nearly 4,000 mutations deliberately engineered into the BRCA1 gene will immediately benefit people undergoing genetic testing for breast or ovarian cancer risk. The study will be published in the Sept. 12 edition of the scientific journal, Nature. Additional data from the research has been made …

While bacteria that produce electricity have been found in exotic environments like mines and the bottoms of lakes, scientists have missed a source closer to home: the human gut. University of California, Berkeley, scientists discovered that a common diarrhea-causing bacterium, Listeria monocytogenes, produces electricity using an entirely different technique from …

Approximately 61 percent of the world’s 356 turtle species are threatened or already extinct, and the decline could have ecological consequences. These findings are according to a paper in the journal BioScience synthesizing the global status of turtles and their ecological roles by scientists from the U.S. Geological Survey, Tennessee …

Researchers at Karolinska Institutet in Sweden have identified four types of neurons in the peripheral auditory system, three of which are new to science. The analysis of these cells can lead to new therapies for various kinds of hearing disorders, such as tinnitus and age-related hearing loss. The study is …

The explosions of stars, known as supernovae, can be so bright they outshine their host galaxies. They take months or years to fade away, and sometimes, the gaseous remains of the explosion slam into hydrogen-rich gas and temporarily get bright again — but could they remain luminous without any outside …

Applying a comprehensive analysis of genetic, historical, and archeological factors in two 6th-century barbarian cemeteries, researchers have gleaned new insights into a key era known as the Migration Period that laid the foundation for modern European society. Spanning the 4th to 8th centuries, this epoch followed the decline of the …

Current WSU research shows stimuli-responsive nanoparticles can specifically target infections to simultaneously prevent the spread of bacteria and reduce the inflammation it causes. These microscopic particles are loaded with antibiotic and anti-inflammatory agents which are released when the particles encounter infection in the body. Researchers in the lab of Pharmaceutical …

Cancer cells often have mutations in their DNA that can give scientists clues about how the cancer started or which treatment may be most effective. Finding these mutations can be difficult, but a new method may offer more complete, comprehensive results. A team of researchers has developed a new framework …

Everyone knows that cars contribute to air pollution. And when most people consider the source, exhaust is usually what comes to mind. However, new research led by the University of Pennsylvania’s Reto Gieré, working with collaborators across the world, is helping to illuminate another significant culprit when it comes to …

Peatlands are extremely effective at storing carbon, but an international study featuring a University of Queensland researcher has found climate change could stop that. The group investigated how peatlands — swamps and bogs with organic rich soils — have responded to climate variability between 850 BCE and 1850 CE. Associate …
