Orthogonal cancer targeting strategy using nanomicelles. a Schematic of the process of photoactivation of Titanocene in disseminated cancer cells in the bone marrow microenvironment

Tumor imaging technique has potential as anti-cancer weapon, mouse study shows. Unlike traditional light therapy – which is limited to the skin and areas accessible with an endoscope – this technique can target and attack cancer cells that have spread deep inside the body, according to researchers at Washington University School of Medicine in St. Louis. Light emitted as part of traditional cancer-imaging techniques, to locate metastatic tumors, also can trigger light-sensitive drugs, according to the new study...

​Magnetic fields play an important role in the places where most massive stars are born. In this illustration, bright spots represent the sources of radio signals from methanol masers, and the curved lines represent the magnetic field.​​​​​​​ ​Wolfgang Steffen/Boy Lankhaar et al.

A team of scientists, led by Boy Lankhaar at Chalmers University of Technology, has solved an important puzzle in astrochemistry: how to measure magnetic fields in space using methanol, the simplest form of alcohol. Their results, published in the journal Nature Astronomy, give astronomers a new way of investigating how massive stars are born.

Over the last half-century, many molecules have been discovered in space...

Astronomers have shown for the first time that they can dynamically detect subatomic- or picometer-sized distortions – changes that are far smaller than an atom – across a 5-foot segmented telescope mirror and its support structure. NASA optics experts are well on the way to toppling a barrier that has thwarted scientists from achieving a long-held ambition: building an ultra-stable telescope that locates and images dozens of Earth-like planets beyond the solar system and then scrutinizes their atmospheres for signs of life.

How well do plant based alternatives fare nutritionally compared to cow’s milk? Journal of Food Science and Technology, 2017; 55 (1): 10 DOI: 10.1007/s13197-017-2915-y

A new study looks at the four most-commonly consumed types of milk beverages from plant sources around the world – almond milk, soy milk, rice milk and coconut milk – and compares their nutritional values with those of cow’s milk. After cow’s milk, which is still the most nutritious, soy milk comes out a clear winner. How healthy is your almond milk really? It may taste good and may not cause you any of the unpleasant reactions caused by cow’s milk...
