Gravity waves evidence
The long search for gravitational waves … may be in the final lap…. Rotating binary stars or, perhaps, other galaxies like the Milky Way but far beyond it, or the center of the Milky Way itself, are likely sources for gravitational radiation. — Science News, June 22, 1968.Update

In Central America’s rain-drenched forests, leaf-cutting ants collect pieces of leaves on which they grow fungi for food. But the rain can hit hard, especially for a small ant. When leaf-cutting ants sense an incoming shower, they hoof it back to their nests, says a study in the May Insectes Sociaux.
Researchers from Argentina, Mexico and Peru tested how one species of leaf-cutting ants...
On a warm summer evening, a visitor to 1920s Göttingen, Germany, might have heard the hubbub of a party from an apartment on Friedländer Way. A glimpse through the window would reveal a gathering of scholars. The wine would be flowing and the air buzzing with conversations centered on mathematical problems of the day. The eavesdropper might eventually pick up a woman’s laugh cutting through...
Apollo milestone at last
The spacecraft fire that killed three Apollo astronauts and rocked the space agency a year and a half ago is still being felt.… Last week, after a series of delays … a major milestone was finally reached: the first manned tests of an Apollo spacecraft to include all the new equipment and safeguards incorporated since the fire. — Science News, June 8, 1968....
News in Brief
Earth’s earliest land-walking vertebrates didn’t paddle about in freshwater lakes or rivers. Instead, these four-footed creatures, which appeared about 375 million years ago, lived in the brackish waters of an estuary or delta, researchers report online May 30 in Nature.
Early tetrapods, such as Ichthyostega and Acanthostega, lived an amphibious existence between land and sea: They had...
Wouldn’t it be grand to have a test that could predict our risk of dreaded diseases like cancer? Signs of such a future exist, but it’s not here yet, as senior writer Tina Hesman Saey explains in the second of our three-part series on direct-to-consumer genetic testing. The tests available today fall short in delivering what we would actually want to know. The raw data are gibberish...05/30/2018 - 07:15 Science & Society, Genetics

If Dr. Seuss had been an astronomer, Horton the Elephant (who heard a Who) would have said “a planet’s a planet, no matter how small.”
But don’t quote Dr. Seuss to the International Astronomical Union. In 2006, the IAU declared Pluto a planet not.
IAU Resolution B5 (not to be confused with Le Petit Prince’s asteroid B 612) declared that in order to be considered...
For the second time in less than a month, DNA probes of family trees in a public database have helped police catch a murder suspect.
On May 17, detectives in Washington arrested 55-year-old William Earl Talbott II of Seatac for the 1987 double murder of Jay Cook and Tanya Van Cuylenborg. A new DNA sleuthing technique called genetic genealogy led to Talbott’s capture. His arrest came just...
The dwindling dusky
In the marshes around America’s spaceport, Kennedy Space Center, live the last few specimens of a bird that may be closer to extinction than even the much-mourned whooping crane. While the whooper might make a gradual comeback if protected and left alone, the dusky seaside sparrow is as good as dead unless man steps in to lend an active hand. — Science News, May...
