Scientists have engineered a hybrid mouse with a gene that predates all animal life. The team replaced a single gene in the mouse stem cells with a version from an ancient, single-celled ancestor, and successfully grew healthy live mice from it.

Sometimes it seems that as soon as an anti-counterfeiting process is created, someone finds a way of circumventing it. A new system could be particularly hard to foil, however, as it utilizes tiny diamonds.

A novel microneedle patch may bring new hope to people who struggle to keep their acne under control. Instead of utilizing antibiotics, the device releases nanoparticles that kill acne-causing bacteria when triggered by exposure to ultrasound.
-
A new light-activated ink can change color on demand. It’s made up of colored microbeads that rise in response to different wavelengths of light to change a surface color, which could be useful for new displays or active camouflage systems.
-
Despite protective measures, endangered fish species are regularly caught then sold in open markets. And while visually searching them out can be difficult, a new technology could more easily allow authorities to know which species are being sold.

MRI is a powerful diagnostic tool, but the size and cost limits where it can be used. A compact, affordable new MRI system uses a much smaller magnetic field and doesn’t require shielding, and is still able to diagnose brain disorders in patients.
-
A new study has shed light on a molecular process underpinning impaired metabolism and endurance in skeletal muscle associated with obesity, and reveals how a growth factor found in a South American plant can alleviate these deleterious effects.
-
NASA’s Curiosity rover has been exploring Gale crater for nine years, studying sediments that look an awful lot like those left behind from an ancient lake. But new research from the University of Hong Kong proposes a much drier explanation.
-
The growing problem of antibiotic resistance isn’t slowing down, which could soon render our best drugs useless against infection. Now, an existing rheumatoid arthritis drug could be repurposed to cancel bacteria’s resistance to antibiotics.
-
A new case study is reporting the first clinically confirmed case of SARS-CoV-2 re-infection. Responding to the news, infectious disease specialists suggest the re-infection is not surprising, could be rare, and may have implications for the efficacy of a vaccine.
-
It's no secret that the world's coral reefs are dying off at an alarming rate. In order to encourage the growth of the coral that remains, scientists from the University of Hong Kong have developed what are known as "reef tiles."

Although many fossils are simply lying exposed on the soil's surface, finding all of them would require a great deal of walking over varying terrain. A new autonomous hexacopter drone could help, as it uses a laser to hunt for fossils at night.
