Cool solutions could head off the climate-damaging rush for air con
Demand for air conditioning will only grow as temperatures rise, sending energy consumption soaring. But there are some interesting ways to deal with the issue, finds Graham Lawton
Astronomers find a giant hiding in the ‘fog’ around a young star
Astronomers have detected a giant exoplanet—between three and ten times the size of Jupiter—hiding in the swirling disk of gas and dust surrounding a young star.
Earlier observations of this star, called MP Mus, suggested that it was all alone without any planets in orbit around it, surrounded by a featureless cloud of gas and dust.
However, a second look at MP Mus, using a combination of results from the Atacama Large Millimeter/submillimeter Array (ALMA) and the European Space Agency’s Gaia mission, suggest that the star is not alone after all.
Activin-A: Muscle Weakness In Cancer Survivors May Be Treatable
Tumors can destroy the blood vessels of muscles even when the muscles are nowhere close to the tumor. That is the key finding of a new study that my colleagues and I recently published in the journal Nature Cancer.
Muscle loss in cancer patients is a major health problem, but the exact causes of how precisely tumors affect muscles remain an active area of research.
Scientists in my lab were curious whether one explanation for the muscle loss in cancer patients could be that the cancer impairs the blood vessels that are necessary to supply nutrients and oxygen to muscles. Healthy blood vessels ensure that blood containing oxygen and nutrients is transported from the heart to all tissues and organs in the body, and then circulates back to the heart. Unhealthy blood vessels lose the ability to circulate sufficient blood and develop leaks, with nutrients seeping into the tissue prematurely and thereby cutting off the supply of nutrients to tissues that are further downstream.
