Tropical deforestation causes widespread degradation of biodiversity and carbon stocks. Researchers were now able to test the relationship between land tenure and deforestation rates in Brazil. Their research shows that poorly defined land rights go hand in hand with increased deforestation rates. Privatising these lands, as is often promoted in the tropics, can only mitigate this effect if combined with strict environmental policies.

The study was conducted at the Rocco Ortenzio Neuroimaging Center at Kessler Foundation, with 62 individuals with relapsing-remitting MS. All completed questionnaires measuring depression, state and trait anxiety, and trait fatigue. While in the scanner, participants underwent a cognitively fatiguing task. In addition to measuring rate of cognitive fatigue, researchers measured whole brain lesion volume and performance during the fatigue-inducing task. “We found that the cognitive rate related to white matter tracts, many with associations with the basal ganglia or what has been proposed as the ‘fatigue network’,” said lead author Dr. Román. “These findings bring us closer to understanding how brain pathology impacts the experience in the moment. This is fundamental to developing effective interventions for managing the disabling fatigue of MS and other neurological conditions.”

Europa is more than just one of Jupiter’s many moons – it’s also one of most promising places in the solar system to look for extraterrestrial life. Under 10 kilometers of ice is a liquid water ocean that could sustain life. But with surface temperatures at -180 Celsius and with extreme levels of radiation, it’s also one of the most inhospitable places in the solar system. Exploring Europa could be possible in the coming years thanks to new applications for silicon-germanium transistor technology research at Georgia Tech.

Researchers found children from families with lower socioeconomic status were more likely to take a bigger risk in hopes of winning a big reward than were children from higher status families.
