Optical magnetic field sensor can detect signals from the nervous system
The human body is controlled by electrical impulses in the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various diseases, for example diseases of the brain or heart problems in young fetuses. Researchers from the Niels Bohr Institute have now succeeded in developing a method for extremely precise measurements of such ultra-small magnetic fields with an optical magnetic field sensor. The results are published in the scientific journal, Scientific Reports. (2016-07-15)

Millions may face protein deficiency as a result of human-caused carbon dioxide emissions
If CO2 levels keep rising as projected, the populations of 47 countries may lose more than 5 percent of their dietary protein by 2050 due to a decline in the nutritional value of rice, wheat, and other staple crops, according to Harvard T.H. Chan School of Public Health researchers. They estimate an additional 250 million people may be at risk of protein deficiency because of elevated CO2 levels. This is the first study to quantify this risk. (2017-08-02)

The critical importance of mangroves to ocean life
Mangrove plants, whose finger-like roots are known to protect coastal wetlands against the ocean and as important fish habitats, cover less than 0.1 percent of the global land surface yet account for a tenth of the dissolved organic carbon (DOC) that flows from land to the ocean. The plants are one of the main sources of dissolved organic matter in the ocean. (2006-02-27)

Double or nothing: Astronomers rethink quasar environment
Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 'protoclusters,' the progenitors of galaxy clusters, in the early Universe, about 12 billion years ago, about ten times more than previously known. They also found that quasars don't tend to reside in protoclusters; but if there is one quasar in a protocluster, there is likely a second nearby. This result raises doubts about the relation between protoclusters and quasars. (2018-03-13)
