New research suggests a counterintuitive new method to make cancer less likely to spread: by normalizing the shape of tumors’ blood vessels to improve their oxygen supply. Such a treatment strategy might also boost the efficacy and reduce resistance to available anti-cancer drugs and so-called anti-angiogenic drugs that work by cutting off the growth of [...]

Animals can re-establish their use of smell to detect siblings, even following an interruption such as prolonged hibernation. Smell is an important animal survival tool. Female ground squirrel sisters bond for protection and use smell to recognize each other. Animals also need to recognize siblings to avoid inbreeding, which would have a negative effect on [...]

When a 91-year-old man was diagnosed with severe blockage of his heart valve — hardening that is formally known as aortic valve stenosis — open-heart surgery was out of the question. He’d already survived quadruple bypass while in his 50s, and having lived almost a century,he wasn’t a good candidate for heart surgery for many [...]
