Electrified methane reformer produces far less carbon dioxide

A team of researchers from several institutions in Denmark, along with colleagues from Sintex and Haldor Topsoe, has developed an electrified methane reformer that produces far less CO2 than conventional steam-methane reformers. In their paper published in the journal Science, the group describes their new technology and how well it works. Kevin Van Geem, Vladimir Galvita and Guy Marin with the Laboratory for Chemical Technology and Center for Sustainable Chemistry in Ghent have published a Perspective piece on the work done by the team in the same journal issue.

How to quell a cytokine storm: New ways to dampen an overactive immune system

BRCA—the family of DNA-repair proteins associated with breast, ovarian prostate, and pancreatic cancers—interacts with a multipart, molecular complex that is also responsible for regulating the immune system. When certain players in this pathway go awry, autoimmune disorders, like lupus, can arise. Now, researchers in the Perelman School of Medicine at the University of Pennsylvania and colleagues at the University of Leeds, United Kingdom, have deciphered the structure of the complex and have found new molecular targets for fighting autoimmunity. Their findings are published this week in Nature.

Declining fertility rates may explain Neanderthal extinction, suggests new model

A new hypothesis for Neanderthal extinction supported by population modelling is put forward in a new study by Anna Degioanni from Aix Marseille Université, France and colleagues, published May 29, 2019 in the open-access journal PLOS ONE.

Patterns of chronic lymphocytic leukemia growth identified

In patients with chronic lymphocytic leukemia (CLL), the rate of disease growth is apt to follow one of three trajectories: relentlessly upward, steadily level, or something in between, scientists at Dana-Farber Cancer Institute, the Broad Institute of MIT and Harvard, Massachusetts General Hospital, and the University of Washington report in a new study. The particular course the disease takes is tightly linked to the genetic make-up of the cancer cells, particularly the number of growth-spurring "driver" mutations they contain.

A rose inspires smart way to collect and purify water

The rose may be one of the most iconic symbols of the fragility of love in popular culture, but now the flower could hold more than just symbolic value. A new device for collecting and purifying water, developed at The University of Texas at Austin, was inspired by a rose and, while more engineered than enchanted, is a dramatic improvement on current methods. Each flower-like structure costs less than 2 cents and can produce more than half a gallon of water per hour per square meter.
