A new way to cleanly separate out cancer cells from a blood sample enables comprehensive genetic profiling of the cancer cells, which could help doctors target tumors and monitor treatments more effectively.

It is a dramatic improvement over current approaches because it also encompasses the variation among cancer cells within a single patient.

“This could be a whole different ball game,” said Max Wicha, the Madeline and Sidney Forbes Professor of Oncology at the University of Michigan and senior physician on the study in Nature Communications.

Given that everything at its base atom is moving maybe our interpretation of reality may be different than its actuality. From shooting photons bouncing off surfaces the world is a cacophony of all sorts of things happening at once.

A provocative new column in Scientific American floats the idea that what’s fundamentally real in the universe — its actual, base reality — isn’t the quarks, fields, and quantum phenomena that seem to comprise it.

Instead, according to scientist and philosopher Bernardo Kastrup, some are starting to suspect that matter itself is an illusion — and that the only real thing is information.

SanDisk’s pioneering 1TB microSD card is available — if you have $450 to spend on it.

The Nickelodeon films for Invader Zim and Rocko’s Modern Life are both coming to Netflix this summer.

They’re already planning to build a prototype of it.

Imperial medical students have helped to devise a new type of ‘decoy’ drug to tackle infections that are resistant to antibiotics.

In lab tests on bacterial cultures, the new drug successfully killed a strain of drug-resistant bacteria. It works by delivering two antibiotics, one of which is effectively hidden. When the bacteria fight against the first ‘decoy’ antibiotic, this action opens up the drug, triggering the second antibiotic into action.

This enables the second antibiotic to be delivered in a targeted way, only being released where it encounters drug-resistant bacteria. The findings could help prolong the life of existing antibiotics by slowing the rate at which bacteria become resistant to them.

These days, scientists can collect a few skin or blood cells, wipe out their identities, and reprogram them to become virtually any other kind of cell in the human body, from neurons to heart cells.

The journey from skin cell to another type of functional cell involves converting them into induced pluripotent stem cells (iPSCs), which are similar to the developmentally immature stem cells found in embryos, and then coaxing them to mature into something different.

But the process runs on an invisible clock, one in which scientists are interested in speeding up so adult-like cells are available when needed, whether for testing drugs for precision medicine, transplanting to repair injury or defect, or better understanding basic biology. It involves an FDA-approved compound called polyinosine-polycytidylic acid, or pIC, a double-stranded RNA molecule that activates a cell’s innate defense system. The compound is commonly used to boost vaccines and chemotherapy. The researchers found that when added to induced pluripotent stem cells undergoing the process of transitioning into cardiac muscle cells, pIC accelerated cellular maturation.

3D printed models of dog skulls are helping University of Queensland vets to save animals and educate tomorrow’s veterinary students.

The models, showcased at the World Science Festival, were the result of a collaboration between UQ Library’s Digital Scholars Hub and the School of Veterinary Science.

UQ veterinarian and Associate Professor Rachel Allavena used the skulls to help children understand how dogs with short noses can suffer from the condition brachycephalia.

Superfast data processing using light pulses instead of electricity has been created by scientists.

The invention uses magnets to record computer data which consume virtually zero energy, solving the dilemma of how to create faster data processing speeds without the accompanying high energy costs.

Today’s data centre servers consume between 2 to 5% of global electricity consumption, producing heat which in turn requires more power to cool the servers.
