Coolidge, of the General Electric Company, demonstrated a new cathode ray tube, with which these rays are for the first time obtained in quantity outside the tube.” Sumner at Cornell University Medical School.” “The valuable constituent of insulin was prepared in crystalline form by Dr. “A machine for automatically coding cipher telegraphic messages was perfected.” Michelson of the University of Chicago announced his new determination of the speed of light as 299,786 km, or 186,284 miles per second.” “The discovery that plants, as well as animals, have in their cells the special bits of living matter known as the sex chromosomes, was announced by Dr. Edwin Hubble of Mount Wilson Observatory to be a sphere of 140 million light years radius, including some 2,000,000 nebulae, all of them embryo or grown stellar systems.” This was one of the measurements that led to proof that the universe extends far beyond the Milky Way and contains countless galaxies with their own star populations. “Observable region of space was shown by Dr. For example, anthropologists regarded the discovery of a Neandertal skull, reported in a story entitled “Woman Finds New Cave Man Skull at Gibraltar,” as an opportunity to learn more about the habits of these extinct “people.” So, what else was hot in science 79 years ago? Some stories covered lines of research still recognized as valuable today. Since 1996, we’ve also put the list up on Science News Online, where it remains one of the most popular features through the following year. ![]() Every year since, the writers at Science News-Letter and later Science News have selected what they consider the current year’s most compelling stories that they had covered. In October of that year, Science Service began publishing a printed weekly newsletter in addition to the mimeographed packet of news stories that the organization had been providing primarily to newspapers. That item from 1926 led the first annual review of “Scientific Events” by Science News-Letter. “Construction of two rigid airships of approximately 6,000,000 cubic foot capacity at cost not over $8,000,000 for both authorized by Congress but no funds appropriated.” The full text of any article can be obtained by Science News subscribers who have registered and signed in. ManchesterĪn asterisk (*) indicates that the text of the item is available free. In an all-carbon version called graphene, electrons moved so fast that they appeared massless, a possible boon for electronics ( ). Physicists isolated one-atom-thick sheets of several materials. A newly described specimen of Archaeopteryx, only the 10th known, provided novel viewing angles of several key body features. Deep-hued plant pigments-such as those coloring these potatoes-were shown to confer health benefits, from fighting heart disease and obesity to preserving memory ( ). Scientists identified the primary chemical components of the pheromone that guides sea lampreys to suitable spawning areas, the first migratory pheromone discovered in a vertebrate and a possible new lamprey-control tool. Researchers said that they had cloned the first canine, an Afghan pup, but the feat was questioned when the scientists later asked to retract a report of other stem cell research. Scientists found that eight of a box jellyfish’s eyes have superb lenses, but their structure prevents them from focusing sharply. ![]() The parasite may facilitate its own spread by making infected people more alluring to mosquitoes. An experimental vaccine against the parasite induced an immune response in people similar to that mustered by people who reside in malaria regions. Two research teams found independently that fungi can kill mosquitoes or at least their efficiency at transmitting the malaria parasite. Cleveland Clinic Foundation MASTERING MALARIA. Researchers discovered that repairing the defect prevents some headaches. Migraines may be among the problems that stem from a common but rarely diagnosed heart defect. ![]() Photograph &Copy 1997 The Detroit Institute of Arts NO HEADACHE. Founders Society purchase, with funds from Mr. During sleep paralysis, a person awakens to a crushing sensation on the chest and senses great danger but can’t move. Cross-cultural investigations identified the widespread phenomenon of sleep paralysis as a factor in various anxiety disorders, including post-traumatic stress disorder and panic disorder, as well as an influence on popular beliefs in a spirit world inhabited by supernatural beings. The high salt content indicates the region once had water coursing through it. Among their recent accomplishments: discovering the first meteorite ever found on a planet other than Earth and identifying the saltiest known region on Mars. Nearly 2 years after they landed, the twin rovers on the Red Planet kept on rolling ( ).
