Fridge-sized contraption makes drugs on demand

by

A new refrigerator-sized factory can rapidly pump out a diverse assortment of drugs on demand. Researchers designed the system to offer a speedy alternative to large-scale pharmaceutical production. Rejiggering chemical inputs and the device’s collection of tanks and tubes allowed the team to produce four different drugs: an anesthetic (lidocaine), an antihistamine (Benadryl), an anti-anxiety ...

by

The Kepler space telescope, NASA’s premier planet hunter, is about to embark on a hunt for planets toward the center of the galaxy. But on April 7, just hours before its new mission was set to begin, the observatory gave astronomers a scare by temporarily hunkering down in an emergency state that prevented mission controllers ...

Scientific evidence should inform politicized debates

by

Over the years, readers have on occasion written to me to point out what they see as an increasing politicization of Science News. These are not accolades — more than one of those readers has contemplated ending their subscription. Some of those critics deny climate change, some oppose GMOs, others view any policy discussion in ... Read more

Gut microbe may challenge textbook on complex cells

by

A gut microbe collected from chinchilla droppings might be the first complex life form to lack even a shred of a supposedly universal organelle. Monocercomonoides, a one-celled gut microbe collected from a pet chinchilla in Prague decades ago, apparently has no mitochondria, the organelles known as the cell’s power plants. Cataloging DNA in the microbe ... Read more

Zapping clouds with lasers could tweak planet’s temperature

by

Laser blasts might help scientists tweak Earth’s thermostat by shattering the ice crystals found in cirrus clouds. Zapping tiny ice particles in the lab forms new, smaller bits of ice, researchers report May 20 in Science Advances. Since clouds with more numerous, smaller ice particles reflect more light, the technique could combat global warming by ... Read more

Animals get safe spots to cross the road — and car collisions drop

by

U.S. 191 is one of the driving options for people headed to Grand Teton or Yellowstone National Parks. But the road also cuts through prime territory for mule deer and pronghorns. And cars and large wildlife don’t usually mix well. When they do tangle, the cars end up heavily damaged, and the animals end up ... Read more

Tight spaces cause spreading cancer cells to divide improperly

by

Scientists have found a new way to study how cancer cells divide and thrive in difficult-to-reach crannies of the body. Transparent artificial membranes — just nanometers thick — can be rolled into tubes to mimic capillaries that host spreading cancer cells, researchers report in the June ACS Nano. Cells squished inside such tubes didn’t organize ... Read more

Scientists throw a curve at knuckleball explanation

by

Knuckleballs baffle baseball players with their unpredictable swerves. A new study suggests a possible cause of the pitch’s erratic flight — sudden changes in the drag force on a ball, due to a phenomenon called a drag crisis. The result is at odds with previous research that attributed the zigzags to the effect of airflow ... Read more
