New research investigating serious incidents occurring in the management of patient remains after their death concludes that safe mortuary care may be improved by applying lessons learned from existing patient safety work.
A Ludwig Cancer Research study has uncovered a key mechanism by which tumors develop resistance to radiation therapy and shown how such resistance might be overcome with drugs that are currently under development.
Cooperatively breeding birds and fish may have evolved the adaptive ability to reduce the size of their eggs when helpers are available to lighten the parental load, a new study suggests. The findings indicate that in some species, the social environment may influence female reproductive decisions even prior to the birth of offspring.
While the world focuses on controlling global warming caused by CO2 emissions from fossil fuels, less attention has been paid to the capacity of vegetation and soils to take up and store carbon. A remote field site in the Norwegian mountains is improving our understanding of carbon cycling in high-latitude alpine areas.
Babies as young as 10 months can assess how much someone values a particular goal by observing how hard they are willing to work to achieve it, according to a new study from MIT and Harvard. This ability requires integrating information about both the costs of obtaining a goal and the benefit gained by the person seeking it, suggesting that babies acquire very early an intuition about how people make decisions.
Through a few clever molecular hacks, researchers at Columbia University Medical Center have converted a natural bacterial immune system into a microscopic data recorder, laying the groundwork for a new class of technologies that use bacterial cells for everything from disease diagnosis to environmental monitoring.
Original concerns that cloning caused early-onset osteoarthritis in Dolly the sheep are unfounded, say experts at the University of Nottingham and the University of Glasgow. The team, who published last year's Nottingham Dollies research which showed that the 8 year-old Nottingham 'Dollies' had aged normally, have now published a radiographic assessment of the skeletons of Dolly herself, Bonnie (her naturally conceived daughter) and Megan and Morag (the first two animals to be cloned from differentiated cells).
Antimalarial drugs chloroquine and hydroxychloroquine could make tumour cells more sensitive to cancer treatment.
The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity. However, all regions of the human brain have molecular signatures very similar to those of our primate relatives, yet some regions contain distinctly human patterns of gene activity that mark the brain's evolution and may contribute to our cognitive abilities, a new Yale-led study has found.
Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a signaling pathway that is essential for angiogenesis, the growth of new blood vessels from pre-existing vessels. The findings, published in Nature Communications, may improve current strategies to improve blood flow in ischemic tissue, such as that found in atherosclerosis and peripheral vascular disease associated with diabetes.
