Scientists have the power to genetically engineer many types of animals. Most Americans think it’s OK to alter or insert genes in animals and insects — provided it’s done in the interest of human health, according to a poll released August 16 from the Pew Research Center. The findings are similar to those from an earlier Pew survey, which found that a majority of Americans are fine with...
The boardwalk at Pa-hay-okee Overlook is a brief, winding path into a dreamworld in Everglades National Park. Beyond the wooden slats, an expanse of gently waving saw grass stretches to the horizon, where it meets an iron-gray sky. Hardwood tree islands — patches of higher, drier ground called hammocks — rise up from the prairie like surfacing swimmers. The rhythmic singing of cricket frogs is...
Rogue nations that want to hide nuclear weapons tests may one day be thwarted by antineutrinos.
Atomic blasts emit immense numbers of the lightweight subatomic particles, which can travel long distances through the Earth. In general, the particles — the antimatter twins of neutrinos — are notoriously difficult to spot. But a large antineutrino detector located within a few hundred...
Salamanders and lizards can both regrow their tails, but not to equal perfection.
While a regenerated salamander tail closely mimics the original, bone and all, a lizard’s replacement is filled with cartilage and lacks nerve cells. That contrast is due to differences between stem cells in the animals’ spinal cords, researchers report online August 13 in Proceedings of the National...
What may be the oldest known solid cheese has been found in an ancient Egyptian tomb.
Made from a mixture of cow milk and either sheep or goat milk, the cheese filled a broken clay jar unearthed from a 13th century B.C. tomb for Ptahmes, the mayor of the ancient city of Memphis, researchers report online July 25 in Analytical Chemistry.
Chemist Enrico Greco, who did the work while...
A distant galaxy appears filled with dark matter.
The outermost stars in the Cosmic Seagull, a galaxy 11.3 billion light-years away, race too fast to be propelled by the gravity of the galaxy’s gas and stars alone. Instead, they move as if urged on by an invisible force, indicating the hidden presence of dark matter, astrophysicist Verónica Motta of the University of Valparaíso in Chile...
Robots, take note: When working in tight, crowded spaces, fire ants know how to avoid too many cooks in the kitchen.
Observations of fire ants digging an underground nest reveal that a few industrious ants do most of the work while others dawdle. Computer simulations confirm that, while this strategy may not be the fairest, it is the most efficient because it helps reduce overcrowding in...
News in Brief
Smoothing out the rough patches of a material widely used to filter saltwater could make producing freshwater more affordable, researchers report in the Aug. 17 Science.
Desalination plants around the world typically strain salt out of seawater by pumping it through films made of polyamide — a synthetic polymer riddled with tiny pores that allow water molecules to squeeze through, but...
Stormfury: Calming the Eyewall08/16/2018 - 12:00 Earth, Climate
Since man cannot muster anything approaching the energy of a hurricane, and so has no hope of overcoming the storm by force, Stormfury attempts to use the giant’s own energy against it…. Last week, Project Stormfury began its 1968 season. — Science News, August 17, 1968.Update
The goal of the U.S. government’s Project Stormfury, which began in...
