Turtle species in serious decline: Broad ecological impacts
About 61 percent of the world's 356 turtle species are threatened or already extinct, and the decline could have ecological consequences, according to a new study.
Biophysics: Pile-ups in protein transport
Motor proteins in cells can move along protein filaments in ways that interfere with each other's progress. A new model shows how this can lead to gridlock, even when there is still plenty of emp..
New high-capacity sodium-ion could replace lithium in rechargeable batteries
Scientists are paving the way to swap the lithium in lithium-ion batteries with sodium, according to newly published research.
Toward an ‘ultra-personalized’ therapy for melanoma
With new immunotherapy treatments for melanoma, recovery rates have risen dramatically, in some cases to around 50 percent. But they could be much higher: A new study shows, in lab dishes and animal s..
A prehistoric thirst for craft beer
Evidence suggests that stone mortars from Raqefet Cave, Israel, were used in brewing cereal-based beer millennia before the establishment of sedentary villages and cereal agriculture.
How key cancer-related enzyme functions
In a new study, researchers have discovered how an enzyme that plays a key role in cancer development functions. The researchers hope the new knowledge will lead to the design of more precise drugs.
Heart attack: Substitute muscle thanks to stem cells
Scientists have for the first time succeeded in generating beating cardiac muscle cells from special stem cells. They may provide a new approach for the treatment of heart attacks.
Cocaine addiction traced to increase in number of orexin neurons
A new study identifies a critical role of the orexin system in the expression of an addicted state in rats.
In drought and heavy rains, ecosystems function like information communication networks
How is a telecommunications network like an ecosystem? Tree canopies and the running streams below, or coral reefs and the ocean waters that flow around them, are interconnected components of a larger..
Sensors that are literally ‘music to one’s ears’
Researchers have found a new use for a 3,000-year-old African musical instrument: detecting toxic substances and counterfeit medications. The sensor, based on the mbira (pronounced 'em-bir'-..
