Until we recognize the essential role of biology, our attempts to truly unify the universe will remain a train to nowhere. ~Robert Lanza Read More
Good health is not something we can buy. However, it can be an extremely valuable savings account. ~Anne Wilson Schaef Read More
The only way forward, if we are going to improve the quality of the environment, is to get everybody involved. ~Richard Rogers Read More
To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science. ~Albert Einstein Read More
Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Heisenberg's Uncertainty Principle, reveal that, as our perception of an object changes, the object itself literally changes. ~Marianne Williamson Read More

A Purdue University chemical engineer has improved upon traditional methods to produce off-the-shelf human immune cells that show strong antitumor activity, according to a paper published in the peer-reviewed journal Cell Reports.
Xiaoping Bao, a Purdue University assistant professor from the Davidson School of Chemical Engineering, said CAR-neutrophils, or chimeric antigen receptor neutrophils, and engraftable HSCs, or hematopoietic stem cells, are effective types of therapies for...

Researchers have designed smart, colour-controllable whitelight devices from quantum dots – tiny semiconductors just a few billionths of a metre in size – which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.
The researchers, from the University of Cambridge, designed the next-generation smart lighting system using a combination of nanotechnology, colour science, advanced computational methods, electronics and a unique fabrication process.
The team found that by using more than the three primary lighting colours used in typical LEDs, they were able to reproduce daylight more accu...

A study into the azinc isotope composition of meteorites by researchers from the University of St Andrews suggests that material from the outer solar system was an important source of volatile elements during the formation of the Earth.
The question of the origin of the volatile elements present on Earth is fundamental to understanding the evolution of our planet...

Researchers train a machine-learning model to monitor and adjust the 3D printing process to correct errors in real-time. A new computer vision system watches the 3D printing process and adjusts velocity and printing path to avoid errors. Training the system in simulation, researchers avoid the costly trial-and-error associated with setting 3D printing parameters for new materials.
Scientists and engineers are constantly developing new materials with unique properties that can be used for 3D printing, but figuring out howto print with these materials can be a complex, costly conundrum.
Often, an expert operator must us...
