Horse Fodder and Other Incredibly Cool Science Stuff

Grazing horses on better pastures

Annual grasses offer options during summer slump



Sudangrass and sorghum-sudangrass showed the greatest yields and regrew the most after grazing. Siberian millet was the lowest yielding grass. Horses most preferred the annual cool-season ryegrass, but among the warm-season grasses, they highly preferred teff and sudangrass. All of the grasses were found to supply adequate nutrition for horses. 


Citrus fruit peel: Potential alternative to mosquito control discovered



The essential oils were extracted in large amounts from the peel of a fruit similar to an orange, which is available throughout many countries in the world. With such ease of access and productions of the oils, it could potentially be used in areas which have little or no access to an alternative.
Believed to be the first ever example of such an experiment, it was found that the essentials oils were highly effective in mosquitocidal activity on the larvae, leading researchers to conclude it could be used as an eco-friendly alternative in mosquitoes control programs.


Bizarre Dwarf Planet Haumea Has Rings


"We started to see something weird in the light curve," Santos Sanz said. The light dimmed just before and after Haumea passed in front of the star, as if something else were obscuring it. "I remember that José Luis, from the first [moments], said, 'OK, this could be a ring,'" Santos Sanz said. Months of scrutiny bore out the scientists' initial suspicions: The results suggest that Haumea's equator is encircled by a 43-mile-wide (70 km) ring of debris located about 620 miles (1,000 km) from the dwarf planet's surface.


Ancient Mars Likely Had Deep-Sea Hydrothermal Vents


"Ancient, deep-water hydrothermal deposits in Eridania basin represent a new category of astrobiological target on Mars," researchers said in the statement. "Eridania seafloor deposits are not only of interest for Mars exploration, they represent a window into early Earth."
