Astronomers have discovered a 2,000-year-old nova remnant

Astronomers have discovered a 2,000-year-old nova remnant

Science
April 29 (UPI) -- An international team of astronomers has identified the ancient remains of a nova inside a galactic globular cluster. Using the Very Large Telescope's MUSE instrument, scientists located the deceased stellar core glowing near the center of globular cluster Messier 22, which is found inside the constellation Sagittarius, 10,600 light-years from Earth. When a nova is ignited, the hydrogen explodes off the surface of the star, leaving behind a brighter stellar envelop. The brightness of a remnant left behind by a nova can last for a several centuries. Astronomers estimate this particular nova was initially spotted some 2,000 years ago. "The position and brightness of the remains match an entry from 48 BC in an ancient collection of observations by Chinese astronomers," Fa...
New frog species discovered on remote Ethiopian mountain

New frog species discovered on remote Ethiopian mountain

Science
Feb. 14 (UPI) -- Biologists have discovered a new species of frog living among the forests on a remote mountain in Ethiopia. The small frog's home is one of the country's last undisturbed forests. Scientists named the new frog species Phrynobatrachus bibita sp. nov.. The amphibian belongs to a group called Ethiopian puddle frogs. DNA analysis confirmed the species is genetically distinct from its closest puddle frog relatives. Human development has impacted wildlife throughout Ethiopia, but the southwestern corner of the country hosts several pockets of remote wilderness. Bibita Mountain is one of the most remote pockets. "Untouched, isolated, and unexplored: it had all the elements to spike our interest," Jacobo Reyes-Velasco, a postdoctoral researcher at New York University who led some...
New measles cases discovered amid outbreaks elsewhere

New measles cases discovered amid outbreaks elsewhere

Health
Three new cases of measles were confirmed by health officials in Houston on Monday, making it the latest city to have the once-eliminated disease appear in recent weeks. The Houston outbreak comes as new cases of measles are being confirmed in Washington state on a daily basis, and other cases have been confirmed in Oregon, Georgia, and New York. The new measles cases in Houston bring the total number of cases in Texas to six so far in 2019. A number of specific details about the cases in Houston have not been publicly disclosed, including how it is believed that the individuals contracted the disease and if they were previously vaccinated. The only details about the three infected individuals that have been released is that two are young boys under the age of 2 and the third is a w...
Israel Defense Forces: Second Hezbollah tunnel discovered

Israel Defense Forces: Second Hezbollah tunnel discovered

World
Dec. 8 (UPI) -- The Israeli military on Saturday said it found a tunnel dug by Hezbollah from Lebanon, the second such passage discovered in a week. Israel Defense Forces accused the militant group, considered a terrorist organization by the United States and Israel, of planning to use the tunnel for violence. "Our troops just exposed a SECOND attack tunnel that Hezbollah dug from Lebanon into Israel," the IDF said on Twitter. "Hezbollah planned to use this tunnel to carry out an attack against Israeli civilians. We won't let them." Israel said it placed explosives inside the tunnel. "Anyone who enters the tunnel does so at their own risk," the IDF tweeted. On Thursday, military officials said it found a similar tunnel dug from the Lebanese village of Ramyeh under the border. They did no...
Scientists have discovered a hidden talent of geckos

Scientists have discovered a hidden talent of geckos

Technology
This is an Inside Science story. The flat-tailed house gecko can not only stick to walls and glide through the air, but also run on water, a new study finds. This discovery of the combination of techniques the reptile uses to race across water could one day lead to robots capable of the same feats, researchers said. The flat-tailed house gecko (Hemidactylus platyurus) is a common pet reptile native to southern and Southeast Asia. Not only can bristles on its toes help it climb walls and hang from ceilings, but it can glide with the aid of its webbed feet and skin flaps. "They're kind of like superheroes -- every time you look at them, they can do more things," said study senior author Robert Full, an integrative biologist at the University of California, Berkeley. The newfound talent...
