Hot 'Blob' Points to a Neutron Star Lurking in Supernova 1987A

Astronomers have long suspected a city-sized neutron star hides within the dusty shroud of SN 1987A. And now, they’re closer than ever to proving their case.

'Roaming reactions' study to shed new light on atmospheric molecules

For the first time, a team of chemists has lifted the hood on the mechanics involved in the mysterious interplay between sunlight and molecules in the atmosphere known as 'roaming reactions', which could make atmospheric modelling more accurate.

New class of laser beam doesn't follow normal laws of refraction

Researchers have developed a new type of laser beam that doesn't follow long-held principles about how light refracts and travels. The findings could have huge implications for optical communication and laser technologies.

40 Years Ago: Voyager 1 Approaches Saturn

The world was waiting for Voyager's encounter with Saturn's when Discover's debut issue hit newsstands in 1980. Since then, the Voyager spacecraft have boldly gone where no probes have gone before.

A closer look at water-splitting's solar fuel potential

Scientists have gained important new insight into how the performance of a promising semiconducting thin film can be optimized at the nanoscale for renewable energy technologies such as solar fuels.

Spintronics: Researchers show how to make non-magnetic materials magnetic

A complex process can modify non-magnetic oxide materials in such a way to make them magnetic. The basis for this new phenomenon is controlled layer-by-layer growth of each material.

Demonstrating the Mpemba effect in a controlled setting

A pair of physicists at Simon Fraser University has developed a means for demonstrating the Mpemba effect in a controlled setting. In their paper published in the journal Nature, Avinash Kumar and John Bechhoefer describe the setup they used, what it showed and other possible uses for it.

Harnessing chaos could help climate modeling take leap forward

Understanding the chaotic variability of the climate and its response to climate change could help scientists better forecast changes that still elude even the most sophisticated models.

An electrical switch for magnetism

NUS physicists have demonstrated the control of magnetism in a magnetic semiconductor via electrical means, paving the way for novel spintronic devices.

Manifestation of quantum distance in flat band materials

A research team found a way to measure the quantum distance of Bloch states in solids by applying magnetic field.
