Mudskipper fish (Periophthalmus barbarus; pictured) use water bubbles as a 'tongue' to feed on land. The finding hints at how other animals might have evolved tongues as they made the transition from aquatic to terrestrial life.Krijn Michel at the University of Antwerp
Stem cells may be useful for treating type 2 diabetes, according to a study in mice.Insulin-producing cells derived from human embryonic stem cells reduce blood sugar levels in mice with type 1 diabetes, but it was unclear whether the approach would work for type
Modern societies require more and more metals, not least for renewable energy generation. Scientists from a range of disciplines are needed to prospect for ore deposits and provide a basis for sustainable exploration.
The status of sea floors is an important part of healthy marine ecosystems and intact coastlines. We need laws and a sea-floor management regime to make the exploitation of marine resources sustainable.
Ore bodies buried deep in Earth's crust could meet increasing global demands for metals, but mining them would be costly and could damage the environment. Reinventing an ancient technology for bioleaching metals could provide a solution.
Boreal forest fires tend to be more intense and lethal in North America than Eurasia. Differences in tree species composition explain these differences in fire regime, and lead to contrasting feedbacks to climate.
Metals often accumulate in the crust beneath volcanoes. Laboratory experiments and observations reveal important roles for magmatic vapours and brines in transporting and concentrating the metals into deposits worth targeting for extraction.
A key goal of cancer therapeutics is to selectively target the genetic lesions that initiate and maintain cancer cell proliferation and survival. While most cancers harbor multiple oncogenic mutations, a wealth of preclinical and clinical data supports that many cancers are sensitive to inhibition of single oncogenes, a concept referred to as ‘oncogene addic […]
Autophagy, the process for recycling cytoplasm in the lysosome, depends on membrane trafficking. We previously identified Drosophila Sbf as a Rab21 guanine nucleotide exchange factor (GEF) that acts with Rab21 in endosomal trafficking. Here, we show that Sbf/MTMR13 and Rab21 have conserved functions required for starvation-induced autophagy. Depletion of Sbf […]
Reductions in brain glucose metabolism have long been associated with Alzheimer's disease. A study now demonstrates that the endothelial glucose transporter GLUT1 is vital for maintaining brain energy metabolism and vascular clearance of amyloid-β.
Chronic cocaine exposure induces long-lasting, transcription-dependent changes in neuronal function. A genome-wide sequencing study shows how cocaine changes the epigenome to exert specific, long-lasting effects on neuronal transcription.
Head direction cells have been hypothesized to form representations of an animal's spatial orientation through internal network interactions. New data from mice show the predicted signatures of these internal dynamics.
