To spread misinformation like wildfire, bots will strike a match on social media but then urge people to fan the flames. Automated Twitter accounts, called bots, helped spread bogus articles during and after the 2016 U.S. presidential election by making the content appear popular enough that human users would trust it and share it more […]
Sometime around 9 p.m., before the second leg of a cross-country flight, my just-turned-4-year-old decided she had had enough. She let out a scream and went full noodle right at the end of a moving walkway in Chicago Midway. I had the baby in a carrier and a death grip on my older daughter’s hand, […]
A Chinese scientist surprised the world in late November by claiming he had created the first gene-edited babies, who at the time of the announcement were a few weeks old. Scientists and ethicists quickly responded with outrage. In an interview with the Associated Press and in a video posted November 25, Jiankui He announced that […]
The grim reality of climate change grabbed center stage in 2018. This is the year we learned that the 2015 Paris Agreement on global warming won’t be enough to forestall significant impacts of climate change. And a new field of research explicitly attributed some extreme weather events to human-caused climate change. This one-two punch made […]
Recognize these rows and columns? You may remember a detail or two about this mighty table’s organization from a long-ago chemistry class. Elements are ordered according to their number of protons, or atomic number. Metals are mostly to the left and nonmetals to the right. The column at the far right holds the noble gases, […]
Mosquito researchers may have hatched a new plan to control the bloodsuckers: Break their eggshells. A protein called eggshell organizing factor 1, or EOF1, is necessary for some mosquito species’ eggs and embryos to develop properly, a new study finds. Genetically disrupting production of that protein in Aedes aegypti mosquitoes caused about 60 percent of […]
Bioengineered blood vessels are one step closer to being available for patients. In clinical trials, these vessels were installed in the arms of dialysis patients and successfully integrated into their circulatory systems, researchers report online March 27 in Science Translational Medicine. The new blood vessels, which eventually host the patient’s own cells after implantation, are […]
The rate of drug abuse or addiction among physicians is from 30 to 100 times that of the general public…. The American Medical Association estimates that some 60,000 of the country’s 316,000 doctors misuse drugs of various kinds. The drug abuser among physicians has a predisposing personality for addiction, and suffers from overwork and fatigue. […]
Black holes capture everything they encounter. From subatomic particles to stars, solids, gases, liquids and even light, everything falls irretrievably in. And even more assuredly, black holes capture the popular imagination. Thinking about space, as humans have since they first gazed at the points of light decorating the nighttime sky, triggers the mind to imagine […]
A new peek at the genetics of beetle genitals reveals the underpinnings of a battle of the sexes. When mating, males of Japan’s flightless Carabus beetles insert a chitin-covered appendage that, once inside a female, pops out a plump sperm-delivery tube as well as a side projection called a copulatory piece. That piece doesn’t deliver […]
