Like most galaxies, the Milky Way hosts a supermassive black hole at its center. Called Sagittarius A*, the object has captured astronomers’ curiosity for decades. And now there is an effort to image it directly.

Catching a good photo of the celestial beast will require a better understanding of what’s going on around it, which has proved challenging due to the vastly different scales involved...

Leading organic chemists synthesize fungal molecule capable of reactivating the self-destruct gene in aggressive cancer cells. Cancers cells use a special technique to propagate; they delete their ‘programmed death’ gene through mutation, ‘forget’ to die when their lifetime is over, and continue to grow instead. A research team has developed a method through which a fungal compound capable of rearming the self-destruct gene in certain cancer cells can be artificially produced in marketable quantities, providing a potential cancer therapeutic strategy.

All human body cells have a certain lifespan, during which they perform their essential duties...

Researchers at the University of Colorado Boulder’s Soft Materials Research Center (SMRC) have discovered an elusive phase of matter, first proposed more than 100 years ago and sought after ever since.

The team describes the discovery of what scientists call a “ferroelectric nematic” phase of liquid crystal in a study published today in the Proceedings of the National Academy of Sciences. The discovery opens a door to a new universe of materials, said co-author Matt Glaser, a professor in the Department of Physics.

Nematic liquid crystals have been a hot topic in materials research since the 1970s...

New research from scientists at Queen Mary University of London has revealed how long-lived Peter Pan discs form, which could provide new insights into how planets arise.

Planet-forming, or protoplanetary discs are giant discs of gas and dust found circling young stars. The recently discovered Peter Pan discs received their name as like their fictional counterpart they are thought to “never grow up,” living around 5-10 times longer than other typical protoplanetary discs.

Whilst astronomers have been aware of the existence of Peter Pan discs since 2016, questions around how and why these discs live so long and the implications for how planets form, have been left unanswered.

In this study, the scientists used computer ...
