Margays (Leopardus wiedii), small wild cats living in forest areas fragmented by agriculture near Campinas and Botucatu in São Paulo State, Brazil, prey on animals inhabiting nearby sugarcane plantations, such as birds and small rodents.
Even novice photographers and videographers who rely on their handheld devices to snap photos or make videos often consider their subject's lighting. Lighting is critical in filmmaking, gaming, and virtual/augmented reality environments and can make or break the quality of a scene and the actors and performers in it. Replicating realistic character lighting has remained a difficult challenge in computer graphics and computer vision.
NASA analyzed the cloud top temperatures in Typhoon Kalmaegi using infrared light to determine the strength of the storm. Kalmaegi is known locally as Ramon in the Philippines where warnings are in effect.
Decades after farmland was abandoned, plant biodiversity and productivity struggle to recover, according to new University of Minnesota research.
Published in the journal Nature Ecology & Evolution, researchers examined 37 years of data tied to plant biodiversity (i.e., number of different species) and plant productivity (i.e., biomass or amount of plants) related to 21 grasslands and savannas in Minnesota. Most of these fields had been ploughed and abandoned for agricultural use between one and 91 years prior.
An obstacle to generating fusion reactions inside facilities called tokamaks is that producing the current in plasma that helps create confining magnetic fields happens in pulses. Such pulses, generated by an electromagnet that runs down the center of the tokamak, would make the steady-state creation of fusion energy difficult to achieve. To address the problem, physicists have developed a technique known as transient coaxial helicity injection (CHI) to create a current that is not pulsed.
When firms design the initial pay package for a new CEO, they focus on that person's tolerance or aversion to risk-taking. Research and corporate governance practices generally recommend compensating a risk-averse CEO with more performance-based pay to incentivize risk taking.
Artificial light at night negatively impacts thousands of species: beetles, moths, wasps and other insects that have evolved to use light levels as cues for courtship, foraging and navigation.
Potato virus Y (PVY) is the most serious problem facing the potato industry in the United States and is the main cause for rejection of seed potato lots. The virus affects potatoes in two ways: It reduces the yield of potato tubers by 70-80% and also negatively affects the quality of the remaining tubers due to necrotic reactions.
A NASA analysis of rainfall rates shows that the once mighty Fengshen is now a depression devoid of heavy rainfall.
On Nov. 17 at 1 p.m. EST (1800 UTC), the Joint Typhoon Warning Center noted that Tropical Depression Fengshen was located near 24.8 degrees north latitude and 157.9 east longitude, approximately 585 nautical miles northwest of Wake Island, and had tracked southeastward. Maximum sustained surface winds were estimated at 30 knots (34.5 mph/55.5 kph) and weakening.
LISA Pathfinder, a mission led by ESA (the European Space Agency) that included NASA contributions, successfully demonstrated technologies needed to build a future space-based gravitational wave observatory, a tool for detecting ripples in space-time produced by, among other things, merging black holes. A team of NASA scientists leveraged LISA Pathfinder's record-setting sensitivity for a different purpose much closer to home -- mapping microscopic dust shed by comets and asteroids.
