Astronomers have made a measurement of a distant neutron star that is one million times more precise than the previous world's best - and they did it by using...nothing.

The interstellar medium is the 'empty' space between stars and galaxies. It's not really empty, it is made up of sparsely spread charged particles and those can be used as a giant lens. The astronomers did just that, to magnify and look closely at the radio wave emission from a small rotating neutron star.

Result: the highest resolution measurement ever achieved, equivalent to being able to see the double-helix structure of our genes from the Moon.

New cancer therapies, particularly agents that block vascular endothelial growth factor (VEGF) signaling, have been successful and are now used as a first line therapy for some tumors, but almost 100% of patients who take VEGF inhibitors (VEGFIs) develop high blood pressure, and a subset develops severe hypertension.

The mechanisms underlying VEGF inhibitor-induced hypertension need to be better understood and there is a need for clear guidelines and improved management, say investigators behind the review in the Canadian Journal of Cardiology.

A new congressionally mandated report from the National Research Council has found that changes EPA has proposed and implemented into its Integrated Risk Information System (IRIS) process are "substantial improvements"  over its old system.

IRIS is used to assess the hazards posed by environmental contaminants but has been rather sporadically followed in the past. A court had to order the EPA to stop blaming fracking for problems without doing a study and the agency has had to defend itself against charges of 'secret' science in determining greenhouse gas policy.

While acknowledging the progress made to date, the report offers further guidance and recommendations to improve the overall scientific and technical validity of the program.

ITHACA, N.Y. – Coffee drinkers, rejoice! Aside from java's energy jolt, food scientists say you may reap another health benefit from a daily cup of joe: prevention of deteriorating eyesight and possible blindness from retinal degeneration due to glaucoma, aging and diabetes.

Raw coffee is, on average, just 1 percent caffeine, but it contains 7 to 9 percent chlorogenic acid, a strong antioxidant that prevents retinal degeneration in mice, according to a Cornell study published in the Journal of Agricultural and Food Chemistry.

You can't open a newspaper without reading about how many people are on welfare in America now. The government is even on a recruitment drive to get more people on benefits, and looking for ways to get them buying organic food too.

That shows a whole lot more money is helping better-off families rather than the very poorest.

Robert A. Moffitt, Professor of Economics at the Johns Hopkins University, notes that the United States is spending 74 percent more in inflation-adjusted dollars on welfare programs in 2007 than in 1975 but the 2.5 million single parent families with the absolute lowest levels of earnings, aid dropped 35 percent between 1983 and 2004. During that same period, aid rose 74 percent for those earning slightly more.

We know some glaciers are growing and we know some glaciers are receding. What we did not know until recently is how many glaciers there are, where they are, and what their extents and volumes are.

That has changed - for the first time reliable calculations of the future development of glaciers and their contributions to regional hydrology and global sea-level rise can be derived from an accurate measurement.

The international team mapped all of the world’s glaciers so all glaciologists can study the impacts of a changing climate on glaciers worldwide, and determine their total extent and volume on a glacier-by-glacier basis. Overall, glaciers cover an area of about 730,000 km² and have a volume of about 170,000 km³.
