Tornadoes in the southeast, Earth’s magnetic field and obesity might not seem to have much in common. Well, now they do.
Under President Donald Trump’s 2018 budget proposal, federal research spending into all three areas — and many others — would decline abruptly. The president delivered his budget request to Congress on May 23, presenting the sharpest picture yet of his administration’s...
Health care quality and availability improved globally from 1990 to 2015, but the gap between the haves and the have-nots widened in those 25 years, researchers report online May 18 in the Lancet.
As an approximate measure of citizens’ access to quality health care, an international team of researchers analyzed mortality rates for 32 diseases and injuries that are typically not fatal...

Carving nanostructures with a laser creates long-lasting colors.
Researchers developed the new printing technique as an alternative to ink-based printing, in which colors fade with time. Aside from eternally vibrant art, the technique could lead to new types of color displays or improve security labels, the scientists report in the May 5 Science Advances.

Cholesterol is so important to life that practically every human cell makes it. Cells use the compound to keep their membranes porous and springy, and to produce hormones and other vital substances. The body can make all the cholesterol it needs, but Americans tend to have a surplus, thanks in large part to too little exercise and too much meat, cheese and grease. Fifty years ago, researchers...
I’ve been to the playground enough times to know a juicy parenting controversy when I see (or overhear) one. Bed-sharing, breastfeeding and screen time are always hot-button issues. But I’m not talking about any of those. No, I’m talking about actual juice.
Some parents see juice as a delicious way to get vitamins into little kids. Others see juice as a gateway drug to a sugar-crusted,...
Huge cuts could be in store for federal science spending if President Donald Trump’s vision for fiscal year 2018 becomes reality.
Although details are skimpy, Trump’s $1.15 trillion budget proposal, released March 16, would make national security the top priority. The budget blueprint calls for a $54 billion increase in defense spending for 2018, offset by an equally big reduction in...
To celebrate birthdays, my 2- and 4-year-old party animals got vaccinated. Measles, mumps, rubella, chicken pox, diphtheria, tetanus and whooping cough for the older one (thankfully combined into just two shots), and hepatitis A for the younger.
Funnily enough, there were no tears. Just before the shots, we were talking about the tiny bits of harmless germs that would now be inside their...
A dinner plate piled high with food from plants might not deliver the same nutrition toward the end of this century as it does today. Climate change could shrink the mineral and protein content of wheat, rice and other staple crops, mounting evidence suggests.
Selenium, a trace element essential for human health, already falls short in diets of one in seven people worldwide. Studies link...
On the Scene
The planning for our supernova special issue began months ago. In one early meeting, astronomy writer Christopher Crockett lit up as he told the story of the night supernova 1987A was discovered. The account has all the ingredients of a blockbuster. There’s a struggle (with an observatory door), the element of surprise (an unexpected burst on a photographic plate), disbelief (by our...
People who undergo gastric bypass surgery are more likely to experience a remission of their diabetes than patients who receive a gastric sleeve or intensive management of diet and exercise, according to a new study. Bypass surgery had already shown better results for diabetes than other weight-loss methods in the short term, but the new research followed patients for five years.
