Cocaine addiction is a chronic disorder with a high rate of relapse for which no effective treatment is currently available. Scientists from the Institut Pasteur, the CNRS, Inserm and the Paris Public Hospital Network (AP-HP) recently demonstrated that two gene mutations involved in the conformation of nicotinic receptors in the brain appear to play a role in various aspects of cocaine addiction.

There are approximately 18 million users worldwide, and cocaine is implicated in more than 50% of overdose deaths in the United States and 25% in France. It is also one of the only drugs for which there is no approved pharmacological treatment.

First measurements of radiation levels on the moon

Informed 2 days ago

In the coming years and decades, various nations want to explore the moon, and plan to send astronauts there again for this purpose. But on our inhospitable satellite, space radiation poses a significant risk. The Apollo astronauts carried so-called dosimeters with them, which performed rudimentary measurements of the total radiation exposure during their entire expedition to the moon and back again. In the current issue (25 September) of the prestigious journal Science Advances, Chinese and German scientists report for the first time on time-resolved measurements of the radiation on the moon.

Scientists precisely measure total amount of matter in the universe

Informed 2 days ago

A top goal in cosmology is to precisely measure the total amount of matter in the universe, a daunting exercise for even the most mathematically proficient. A team led by scientists at the University of California, Riverside, has now done just that.

Astronomers model, determine how disk galaxies evolve so smoothly

Informed 4 days ago

Computer simulations are showing astrophysicists how massive clumps of gas within galaxies scatter some stars from their orbits, eventually creating the smooth, exponential fade in the brightness of many galaxy disks.

Astronomers discover an Earth-sized “pi planet” with a 3.14-day orbit

Informed 4 days ago

In a delightful alignment of astronomy and mathematics, scientists at MIT and elsewhere have discovered a “pi Earth” — an Earth-sized planet that zips around its star every 3.14 days, in an orbit reminiscent of the universal mathematics constant.

Jupiter's Moons Could be Warming Each Other

New Hubble Data Suggests There is an Ingredient Missing from Current Dark Matter Theories

Informed 3 weeks ago

Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope (VLT) in Chile have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. The new findings indicate that some small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.
