New research finds that a protein that fuels an inflammatory pathway does not turn off in breast cancer, resulting in an increase in cancer stem cells. This provides a potential target for treating triple negative breast cancer, the most aggressive form of the disease. Fuente :...

The longer the period of time a child is bullied, the more severe and lasting the impact is on a child's health, according to a new study from Boston Children's Hospital published online Feb. 17 in Pediatrics. The study is the first to examine the compounding effects of bullying from elementary...

One of science's strongest dogmas is that complex life on Earth could only evolve when oxygen levels in the atmosphere rose to close to modern levels. But now studies of a small sea sponge fished out of a Danish fjord shows that complex life does not need high levels of oxygen in order to live and...

As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and...

Teenage boys who show a combination of depressive symptoms and elevated levels of the 'stress hormone' cortisol are up to fourteen times more likely to develop major depression than those who show neither trait, according to research funded by the Wellcome Trust. Fuente :...

Researchers have pinpointed why normal aging is accompanied by a diminished ability to regain strength and mobility after muscle injury: over time, stem cells within muscle tissues dedicated to repairing damage become less able to generate new muscle fibers and struggle to self-renew. Scientists...

En California, los investigadores del Laboratorio Long Marine y la leona marina Ronan han puesto en entredicho las teorías sobre la capacidad rítmica animal. Después de que los científicos le enseñaran a mover su cabeza al oír ciertos ritmos, la loba de mar ha aprendido a hacerlo con melodías que jamás ha escuchado antes. Se...
