#SCIENCE DAILY BIOLOGY MANUAL#
Researchers connected to the Conservation Biology Institute in Corvallis have created a manual of sorts for Oregon to meet international biodiversity and climate goals (protecting 50% of forestland by 2050). They preserve drinking water quality and biodiversity and act as one of the greatest carbon sinks in the Western United States. Standing forests do a lot for us in the Pacific Northwest.

And the scientists say this model could be used when designing underwater vehicles to achieve the best of both worlds. It might not sound like a big deal, but these nectophores allow the jellies to achieve speed and efficient motion - something that’s actually pretty rare. They can move them all at the same time or in sequence, depending on whether they’re trying to escape from a predator or just out for a leisurely swim. The jelly uses jet propulsion that’s created when squishy structures called nectophores contract and undulate, propelling them forward. Researchers at the University of Oregon are taking their inspiration from a tiny jellyfish-like creature called Nanomia bijuga, which has a really cool way of getting around. And why not? Plants and animals have had millions of years of evolution behind them to get it right.
Scientists often look to biology to solve engineering problems. In this photo released by the University of Oregon, Nanomia bijuga, a marine animal related to jellyfish, swims via jet propulsion. Read the paper from the Journal of Pineal Research here. The researchers concluded something we could all maybe take a pro-tip from: In the winter, the students just weren’t getting enough early-day light exposure, making them naturally want to go to sleep later. An hour of evening light exposure pushed it back by 15 minutes. The data showed that every hour of light exposure in the morning pulled the students’ circadian cycle (when your body naturally wants to sleep) up 30 minutes. The scientists believe the cause has to do with light exposure - and what time of day that exposure happens. The scientists tracked the sleep schedules of about 500 UW students and found they went to bed later during the dark winter months than in summer when there’s much more daylight.

Scientifically speaking, researchers at the University of Washington are studying how to make that happen. Unscientifically speaking, desire for more and better sleep is pretty much a modern-day human universal. Read the paper from the journal Science Advances here. They’re the oldest points ever found in the Americas.Īnd not only are the artifacts old, they’re very similar in style to points uncovered in Japan from 16,000-20,000 years ago, meaning the first Americans may have been genetically and culturally connected to those groups. They’ve dated 14 projectile points (similar to arrowheads) found at an early-human site on traditional Nez Perce land in Idaho to nearly 15,800 years ago. Researchers from Oregon State University are adding to the evidence of an earlier migration. And for a long time, 13,500 years ago was the date - that’s when the Bering Land Bridge between what’s now Alaska and Russia was exposed.īut more recently, archeological discoveries have pushed that first-arrival date way back. Stone projectile points discovered buried inside and outside of pit features at the Cooper’s Ferry site.įor decades, scientists have debated when humans first crossed from Asia to North America.
