Researchers have put DNA evidence together with long-term genealogical data to explore questions of biological fatherhood on a broad scale among people living in parts of Western Europe over the last 500 years. The study found evidence of extra-pair paternity events turned up more often in people of lower socioeconomic status who lived in densely populated cities in the 19th century.

The dopamine D2 receptor has a previously unobserved role in modulating Wnt expression and control of cell proliferation, according to a new study. The research could have implications for the development of new therapeutics across multiple disciplines including nephrology, endocrinology, and psychiatry.

Some chemical alternatives to plastic bisphenol-A (BPA), which is still commonly used in medical settings such as operating rooms and intensive care units, may be less disruptive to heart electrical function than BPA, according to a pre-clinical study that explored how the structural analogues bisphenol-S (BPS) and bisphenol-F (BPF) interact with the chemical and electrical functions of heart cells.

During spaceflight, astronauts experience similar physical stress as cancer patients undergoing treatments such as chemotherapy, immunotherapy, and targeted therapy. Researchers suggest that by mimicking a NASA astronaut's schedule of exercising before, during, and after a mission, cancer patients could reduce the long-term impact their treatments often have on their bodies.

Contrary to the previous data, a Finnish study clarifies that smoking and high blood pressure do not protect from death in patients suffering from subarachnoid haemorrhage, the most lethal stroke subtype. In fact, subarachnoid haemorrhage kills smokers and hypertensive individuals already before they reach hospitals, and therefore studies that cannot include these outside hospitals deaths in analyses may reach erroneous conclusions.

An international research team sought to find out whether cooperation between humans and machines is different if the machine purports to be human. They carried out an experiment in which humans interacted with bots. The scientists show that bots are more successful than humans in certain human-machine interactions -- but only if they are allowed to hide their non-human identity.

A new study found that one third of a group of patients seeking treatment for buying-shopping disorder (BSD) also reported symptoms of addictive online shopping. These patients tended to be younger than the others in the study sample, experienced greater levels of anxiety and depression, and were likely to exhibit a higher severity of BSD symptoms.
