Scientists develop tiny tooth-mounted sensors that can track what you eat

Monitoring in real time what happens in and around our bodies can be invaluable in the context of health care or clinical studies, but not so easy to do. That could soon change thanks to new, miniaturized sensors developed by researchers that, when mounted directly on a tooth and communicating wirelessly with a mobile device, can transmit information on glucose,  and salt intake. Researchers note that future adaptations of these sensors could enable the detection and recording of a wide range of nutrients, chemicals and physiological states, according to Science Daily.

Previous wearable devices for monitoring dietary intake suffered from limitations such as requiring the use of a mouth guard, bulky wiring, or necessitating frequent replacement as the sensors rapidly degraded. Engineers sought a more adoptable technology and developed a sensor with a mere 2mm x 2mm footprint that can flexibly conform and bond to the irregular surface of a tooth. In a similar fashion to the way a toll is collected on a highway, the sensors transmit their data wirelessly in response to an incoming radiofrequency signal.

Interstellar asteroid, 'Oumuamua, likely came from a binary star system

New research finds that 'Oumuamua, the rocky object identified as the first confirmed interstellar asteroid, very likely came from a binary star system, according to Science Daily.

"It's remarkable that we've now seen for the first time a physical object from outside our Solar System," says lead author Dr Alan Jackson.

A binary star system, unlike our Sun, is one with two stars orbiting a common centre.

For the new study, Jackson and his co-authors set about testing how efficient binary star systems are at ejecting objects. They also looked at how common these star systems are in the Galaxy.

Rattlesnake VENOM could hold the key to fighting antibiotic-resistant superbugs

A compound found in rattlesnake venom has the potential to replace conventional antibiotics, according to a new study.

The research claims that the animals might be the answer to growing concerns about antibiotic resistance and the scarcity of antibiotics in development , according to Daily Mail.

The researchers explained how the venom works without damaging healthy cells.

The enemy within: Gut bacteria drive autoimmune disease

Bacteria found in the small intestines of mice and humans can travel to other organs and trigger an autoimmune response. The researchers also found that the autoimmune reaction can be suppressed with an antibiotic or vaccine designed to target the bacteria, they said, according to Science Daily.

The findings, suggest promising new approaches for treating chronic autoimmune conditions, including systemic lupus and autoimmune liver disease, the researchers said.

Human brain TRIPLED in size

gradually over three million years as we developed culture, language, and the ability to make tools

The evolution of the human brain may have occurred far more gradually than previously believed, according to Daily Mail.

A new study on nearly 100 fossils from several different human species has found that brain size tripled over the course of the last three million years, in a process that was likely slow and consistent, as opposed to a series of 'step-like increases.'
