Researchers, in a recent study, were surprised to learn that they could take the exact same number of seeds from the same plants, put them in agricultural fields across the Mid-Atlantic region and get profoundly different stands of cover crops a few months later.
OCT-based technique captures subtle details of photoreceptor function

Researchers have developed a new instrument that has, for the first time, measured tiny light-evoked deformations in individual rods and cones in a living human eye. The new approach could one day improve detection of retinal diseases such as age-related macular degeneration, a leading cause of blindness in people over 55 worldwide.

Songbirds, like people, sing better after warming up

If you've ever been woken up before sunrise by the chirping of birds outside your window, you may have wondered: why do birds sing so loud, so early in the morning? The cacophony is mostly males, whose songs are meant to impress potential mates and rivals. Researchers say there may be a good reason why birds are most vocal at first light. By singing early and often, birds perform better during the...

Citizen Scientists Discover Dozens of New Cosmic Neighbors in NASA Data
We’ve never met some of the Sun’s closest neighbors until now. In a new study, astronomers report the discovery of 95 objects known as brown dwarfs, many within a few dozen light-years of the Sun. They’re well outside the solar system, so don’t experience heat from the Sun, but still inhabit a region astronomers consider our cosmic neighborhood. This collection represents some of the...
Plantwatch: how a miraculous moss keeps cool in the Mojave desert
Sheltering under translucent quartz stones shields the moss from heat, cold, drought and intense ultraviolet raysA small moss growing in the Mojave desert in California uses a remarkable protection from the desert sun – it shelters under translucent quartz stones. It is a miniature greenhouse that shields the moss from heat, cold, drought and intense ultraviolet rays.The desert gets extremely...
Enzyme cocktail developed in Brazil powers production of second-generation ethanol
Researchers at the Brazilian Center for Research in Energy and Materials (CNPEM) have genetically engineered a fungus to produce a cocktail of enzymes that break down the carbohydrates in biomass, such as sugarcane trash (tops and leaves) and bagasse, into fermentable sugar for industrially efficient conversion into biofuel.
Machine learning unearths signature of slow-slip quake origins in seismic data
- ScienceDaily

Combing through historical seismic data, researchers using a machine learning model have unearthed distinct statistical features marking the formative stage of slow-slip ruptures in the earth's crust months before tremor or GPS data detected a slip in the tectonic plates.
