Researchers at Oregon State University have developed a new way to monitor the danger associated with algae blooms — “sniffing” the water for gases associated with toxins.
Gravitational waves are back, and they’re bigger than ever. After the historic first detection of the space-time rattles in 2015 using ground-based detectors, researchers could have now rediscovered Albert Einstein’s waves with an entirely different technique.
You can't see or feel it, but everything around you — including your own body — is slowly shrinking and expanding. It's the weird, spacetime-warping effect of gravitational waves passing through our galaxy, according to a new study by a team of researchers with the U.S. National Science Foundation's NANOGrav Physics Frontiers Center. "While our early data told us that we were hearing something, we now know that it’s the music of the gravitational universe," said NANOGrav co-director and Oregon State University astrophysicist Xavier Siemens.
Scientists on Wednesday unveiled evidence that gravitational waves, the ripples in the fabric of space-time predicted by Albert Einstein more than a century ago, are permeating the universe at low frequencies - creating a cosmic background hum. "The gravitational waves actually stretch and compress space-time itself as they travel through the universe," said Oregon State University astrophysicist Jeff Hazboun.
Radio telescopes around the world picked up a telltale hum reverberating across the cosmos, most likely from supermassive black holes merging in the early universe.
The very fabric of the cosmos is constantly being roiled and rumpled all around us, according to multiple international teams of scientists that have independently found compelling evidence for long-theorized space-time waves.
Astrophysicists using large radio telescopes to observe a collection of cosmic clocks in our Galaxy have found evidence for gravitational waves that oscillate with periods of years to decades. “The large number of pulsars used in the NANOGrav analysis has enabled us to see what we think are the first signs of the correlation pattern predicted by general relativity,” says Oregon State University’s Dr. Xavier Siemens, co-Director of the NANOGrav PFC.
Scientists say they are starting to find signs of an elusive type of rumbling through space that could be created by the biggest, baddest black holes in the universe.
A breakthrough identification of distant signals in space is shedding new light on gravitational waves — one of science’s biggest mysteries. Now, an international research team including researchers at Oregon State University have detected compelling evidence of much more faint gravitational wave signals with periods (the time it takes for a full wave cycle) of years to decades.
Microscopic algae that corals need for survival harbor a common and possibly disease-causing virus in their genetic material, an international collaboration spearheaded by OSU microbiologist Rebecca Vega Thurber has found.
A new breakthrough in zinc battery technology by chemistry professor David Ji was one of the top five Pacific Northwest science stories selected in in OPB's monthly roundup.
According to a new research study led by Will Fennie, a graduate student in integrative biology at OSU, larvae produced by black rockfish have fared better over the last two years thanks to the "unusually high" ocean temperatures.
Corvallis chemistry professor David Ji has unlocked efficient zinc batteries, an energy storage breakthrough with big implications for sources of electricity that aren’t derived from fossil fuels.
Scientists are naming a rare species of beetle in honor of former California Gov. Jerry Brown after finding one at his ranch. David Maddison, an OSU biology professor and beetle expert, was called on to help identify the previously unnamed species.
New research from College of Science Professor Xiulei “David” Ji may have unlocked a key development in safe and sustainable zinc-based battery technology.
The long-term impacts of acidification on ocean waters are causing higher mortality in sea life. Marine biologist Francis Chan is among the OSU scientists who are working hard to help coastal communities recover.
Masses of tangled brown seaweed that typically spend most of the year floating around in the open waters of the Atlantic Ocean are once again drifting toward shore, where they could pose a significant threat to coastal environments and beach communities. Francis Chan, College of Science associate professor and director of the Cooperative Institute for Marin Ecosystem and Resources Studies weighed in on what this means for ecosystems.
