Researchers at ORA in Montreal, Canada, say they have developed the first consumer-ready loudspeaker from graphene oxide. The technology is compatible with current speaker and audio systems and could find its way into many commercial products in the not too distant future, says company co-founder Xavier Cauchy.
In recent years, a growing body of evidence has suggested that phthalates—synthetic chemicals used in scores of products ranging from vinyl flooring to food packaging to medical tubing to cosmetics—can cause reproductive harms. Now, two new studies from Harvard T.H. Chan School of Public Health have revealed that these hormone-disrupting chemicals may increase both the risk of miscarriage and risk factors for gestational diabetes.
Following seven successful months of colliding proton beams with each other in the search for new fundamental particles, the LHC today began colliding proton beams with beams made up of heavy ions – the nuclei of lead atoms.
A composite image of the “bullet cluster,” a galaxy cluster formed by a collision of two clusters. The pink clumps show hot gas containing most of the normal matter, while the two blue clumps reveal where most of the mass in the clusters is actually contained. This provides evidence for dark matter since most of the mass was expected to be concentrated around the pink areas.
An experiment to explore the aftermath of cosmic dawn, when stars and galaxies first lit up the universe, has received nearly $10 million in funding from the National Science Foundation to expand its detector array in South Africa.
