New research by scientists from Harvard University, NASA’s Jet Propulsion Laboratory and the UK Centre for Astrobiology shows that widespread regions of the surface of Mars could be made habitable to photosynthetic life via a solid-state analogue to Earth’s greenhouse effect. Through experiments and modeling under Martian environmental conditions, the …

In a study done in mice, a team of researchers at Kumamoto University, Japan, demonstrated that Matcha tea powder exerts strong and synergistic anxiolytic (anti-anxiety) effects, and that the activation of the dopamine D1 and serotonin 5-HT1A receptors contributes to such effects.
