Molecular reporters expose the allies of the brain tumor

Glioblastoma is the most common malignant brain tumor in adults. Roughly five in every 100,000 people develop this type of cancer each year. The diagnosis amounts to a death sentence: Even after surgical resection followed by radiation and chemotherapy, the glioblastoma will kill the patient in a few months. This is because the tumor invariably returns after treatment, and in a more aggressive form than before.

Caspian crisis: Sinking sea levels threaten biodiversity, economy and regional stability

Coastal nations are rightly worried about sea level rise, but in the countries around the Caspian Sea, over 100 million people are facing the opposite problem: an enormous drop in sea level. Technically, this sea is a land-locked lake, but it is the largest on the planet (371.000 km2), and quite salty. Since the '90s, the water level has been dropping a few centimeters every year. This drop will accelerate during the upcoming decades, according to scientists from the German universities of Gießen and Bremen, together with Dutch geologist Frank Wesselingh.

Genetic engineering without unwanted side effects helps fight parasites

Modified CRISPR-Cas9 gene editing scissors are enabling researchers at the University of Zurich to make alterations to the genetic material of single-cell organisms that are indistinguishable from natural mutations. This method makes it possible to develop a harmless experimental live vaccine for the widespread parasite Toxoplasma gondii.

How the American child welfare system lost its way

Black children are removed from their families at much greater rates than any other race or ethnicity in this country. At the same time the sheer number of all child abuse investigations in the US is staggering: experts estimate that by age 18 one out of three children has been the subject of a child protective services investigation. Yet, many of these investigations and removals are unjustified and stem from a misguided policy shift that began in the late 1960s, says University of Rochester health policy historian and physician Mical Raz.
