commercial loudspeaker

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.

SpaceX aims to launch internet from space

Private rocket firm SpaceX has applied for government permission to launch satellites that will provide global broadband internet access.

In a filing to the US Federal Communications Commission (FFC), it laid out details about its plans for a 4,425-strong satellite network.

It is one of several companies aiming to deploy satellite-based internet services over the next few years.

SpaceX suffered a setback in September when a rocket exploded.

Exposure to phthalates may raise risk of pregnancy loss, gestational diabetes

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.

Why do seabirds eat plastic? The answer stinks

Exposure to influenza viruses during childhood gives people partial protection for the rest of their lives against distantly related influenza viruses, according to a new study in the journal Science.

Brain Interfaces

Researchers at Duke University want to help colleagues around the world eavesdrop on tens of thousands of neurons at once.

Lead ion and proton: Close encounters of the third kind

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.

3 knowns and 3 unknowns about dark matter

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.

HERA project

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.
