UNC-Chapel Hill researchers kill drug-resistant lung cancer with 50 times less chemo: Cancer drugs packaged in immune bubbles home in directly to tumors without getting sidetracked and destroyed; less chemo with better result

The cancer drug paclitaxel just got more effective. For the first time, researchers from the University of North Carolina at Chapel Hill have packaged it in containers derived from a patient's own immune system, protecting the drug from being destroyed by the body's own defenses and bringing the entire payload to the tumor.

New particle can track chemo: Discovery could reveal how well -- and how fast -- treatment finds and kills cancer

Tracking the path of chemotherapy drugs in real time and at a cellular level could revolutionize cancer care and help doctors sort out why two patients might respond differently to the same treatment.

Researchers at The Ohio State University have found a way to light up a common cancer drug so they can see where the chemo goes and how long it takes to get there.

The Turbulent Birth of a Quasar

ALMA reveals secrets of most luminous known galaxy in Universe

Quasars are distant galaxies with very active supermassive black holes at their centres that spew out powerful jets of particles and radiation. Most quasars shine brightly, but a tiny fraction of these energetic objects are of an unusual type known as Hot DOGs, or Hot, Dust-Obscured Galaxies, including the galaxy WISE J224607.57-052635.0, the most luminous known galaxy in the Universe.

First all-antiferromagnetic memory device could get digital data storage in a spin

If you haven't already heard of antiferromagnetic spintronics it won't be long before you do. This relatively unused class of magnetic materials could be about to transform our digital lives. They have the potential to make our devices smaller, faster, more robust and increase their energy efficiency.

Physicists at The University of Nottingham, working in collaboration with researchers in the Czech Republic, Germany and Poland, and Hitachi Europe, have published (2pm US ET Thursday 14 January 2016) new research in the prestigious academic journal Science which shows how the 'magnetic spins' of these antiferromagnets can be controlled to make a completely different form of digital memory.

NASA's Stardust Sample Return was 10 Years Ago Today

It was less than an hour into the new day of January 15, 2006 (EST), when tens of thousands of miles above our planet, two cable cutters and two retention bolts fired, releasing a spring which pushed a 101-pound (46-kilogram) sample return capsule away from its mother ship. Later, during its final plunge Earthward, the capsule would become the fastest human-made object to enter our atmosphere, achieving a velocity of about 28,600 mph (12.8 kilometers per second).

Shiny fish skin inspires nanoscale light reflectors

A nature-inspired method to model the reflection of light from the skin of silvery fish and other organisms may be possible, according to Penn State researchers.

Such a technique may be applicable to developing better broadband reflectors and custom multi-spectral filters for a wide variety of applications, including advanced optical coatings for glass, laser protection, infrared imaging systems, optical communication systems and photovoltaics, according to Douglas Werner, John L. and Genevieve H. McCain Chair Professor in Electrical Engineering, Penn State.

New LED with luminescent proteins

Scientists from Germany and Spain have discovered a way to create a BioLED by packaging luminescent proteins in the form of rubber. This innovative device gives off a white light which is created by equal parts of blue, green and red rubber layers covering one LED, thus rendering the same effect as with traditional inorganic LEDs but at a lower cost.

How copper makes organic light-emitting diodes more efficient: KIT researchers measure intersystem crossing directly in a thermally activated delayed fluorescence copper complex -- publication in Science Advances

Use of copper as a fluorescent material allows for the manufacture of inexpensive and environmentally compatible organic light-emitting diodes (OLEDs). Thermally activated delayed fuorescence (TADF) ensures high light yield. Scientists of Karlsruhe Institute of Technology (KIT), CYNORA, and the University of St Andrews have now measured the underlying quantum mechanics phenomenon of intersystem crossing in a copper complex. The results of this fundamental contribute to enhancing the energy efficiency of OLEDs.
