The Maryland Senate voted on Saturday to allow patients access to medical marijuana at state-licensed dispensaries. The bill now moves to the state’s lower chamber.

Maryland would join 14 other states in legalizing medical marijuana. The neighboring District of Columbia legalized it in a 1998 referendum that was only recently allowed by Congress to go into effect. The District’s city council is writing rules to establish the city’s medical marijuana policy.

Current Maryland law allows defendants charged with pot possession to cite a medical necessity defense. If a judge deems the drug to be beneficial, a maximum hundred dollar civil fine is imposed. Read the full story

SOMETHING big is out there beyond the visible edge of our universe. That’s the conclusion of the largest analysis to date of over 1000 galaxy clusters streaming in one direction at blistering speeds. Some researchers say this so-called “dark flow” is a sign that other universes nestle next door.

Last year, Sasha Kashlinsky of the Goddard Space Flight Center in Greenbelt, Maryland, and colleagues identified an unusual pattern in the motion of around 800 galaxy clusters. They studied the clusters’ motion in the “afterglow” of the big bang, as measured by the Wilkinson Microwave Anisotropy Probe (WMAP). The photons of this afterglow collide with electrons in galaxy clusters as they travel across space to the Earth, and this subtly changes the afterglow’s temperature. Read the full story
