PORTLAND, ORE. — A great flower shape for a moth trying to get a drink in the dark turns out to be awful from the plant’s point of view.
Offering hawk moths (Manduca sexta) a range of 3-D printed flowers with different curvatures shows that a moderately curved trumpet shape lets moths sip most efficiently, Foen Peng reported June 24 at the Evolution 2017 meeting. That’s a win for a...
Once every 53 days, Jupiter pulls Juno close. Locked in orbit since July 2016, the spacecraft has made five close flybys of the planet so far. More than 1,300 Earths could fit inside Jupiter, but Juno takes only two hours to zip from pole to pole. That mad, north-to-south trek is shown below in a sequence of 14 enhanced-color images taken May 19.
Each image’s width corresponds to the...
Hurricane season has officially begun in the North Atlantic, and it’s not just coastal communities that have to worry. A population of sooty terns off the southwest tip of Florida might want to worry, too. Depending on when and where storms hit, the terns could be in for a tough time. Their migratory route overlaps with the general path of hurricanes traveling from the waters off Africa up to...

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...
