What your Facebook picture says about your background

For millions of its Western users, the picture they choose to illustrate themselves on Facebook is an important decision to make. They know it can be the first impression that anyone in the world receives of them, so they’re often deeply conscious of what features are displayed and what flaws are hidden by their chosen image. But despite their careful deliberation the decision may not be a personal or independent one at all – the choice may be more conditioned by cultural factors than anyone assumes.

Greenland’s loss of ice mass during the last 10 years is unusually high compared to last 50 years

Loss through melting and iceberg calving during the last 10 years is unusually high compared to the last 50 years. The Greenland ice sheet continues to lose mass and thus contributes at about 0.7 millimeters per year to the currently observed sea level change of about 3 mm per year. This trend increases each year by a further 0.07 millimeters per year. The pattern and temporal nature of loss is complex. The mass loss is largest in southwest and northwest Greenland; the respective contributions of melting, iceberg calving and fluctuations in snow accumulation differing considerably.

Three percent of US executions since 1900 were botched, study finds

Of approximately 9,000 executions that took place from 1900 to 2011, 270 of them involved some problem, according to a new study. Researchers created a database of all the “departures from the protocol of killing someone sentenced to death” in the past 111 years.

Children exposed to the common pollutant naphthalene show signs of chromosomal damage

Children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer. These include chromosomal translocations, a potentially more harmful and long-lasting subtype of CAs.

Ion-based electronic chip to control muscles: Entirely new circuit technology based on ions and molecules

An integrated chemical chip has just been developed. An advantage of chemical circuits is that the charge carrier consists of chemical substances with various functions. This means that we now have new opportunities to control and regulate the signal paths of cells in the human body. The chemical chip can control the delivery of the neurotransmitter acetylcholine. This enables chemical control of muscles, which are activated when they come into contact with acetylcholine.
