A protein in the immune system can be manipulated to help overcome bowel cancer, according to new research from The Australian National University (ANU). The research is published in Science Advances.

Bowel cancer claims more than 100 lives in Australia each week, yet around 90% of cases can be successfully treated if detected early.

According to lead author Dr. Abhimanu Pandey, from ANU, the protein, known as Ku70, can be activated or “turned on” like a light switch by using a combination of new and existing drugs.

“In its activated state, the protein acts like a surveillance system, detecting signs of damaged DNA in our cells,” Dr. Pandey said.

“DNA is the genetic code of life...

What happens when you expose tellurite glass to femtosecond laser light? That’s the question that Gözden Torun at the Galatea Lab at Ecole Polytechnique Federale de Lausanne, in collaboration with Tokyo Tech scientists, aimed to answer in her thesis work when she made the discovery that may one day turn windows into single material light-harvesting and sensing devices. The results are published in Physical Review Applied.

Interested in how the atoms in the tellurite glass would reorganize when exposed to fast pulses of high energy femtosecond laser light, the scientists stumbled upon the formation of nanoscale tellurium and tellurium oxide crystals, both semiconducting materials etched into the glass, precisely where the glass had been exposed...

Physicists discovered stars near the edge of the Milky Way travel more slowly than those closer to its center — a surprise suggesting our galaxy’s gravitational core may have less dark matter than previously thought.

By clocking the speed of stars throughout the Milky Way galaxy, MIT physicists have found that stars further out in the galactic disk are traveling more slowly than expected compared to stars that are closer to the galaxy’s center. The findings raise a surprising possibility: The Milky Way’s gravitational core may be lighter in mass, and contain less dark matter, than previously thought.

The new results are based on the team’s analysis of data taken by the Gaia and APOGEE instruments...
