No convincing scientific evidence that hangover cures work, according to new research
Peer-Reviewed Publication
A new systematic review has found only very low-quality evidence that substances claiming to treat or prevent alcohol-induced hangover work.
In a paper published in National Science Review, an international team of scientists evaluate scenarios about what is causing methane concentrations to rapidly increase in the atmosphere. By combining new and novel isotopic datasets on methane source ‘signatures’ with simple atmospheric models, they ran thousands of potential emission pathways and isolated those that best matched the observed change of methane isotopes in the atmosphere. Using this approach, the authors found that the methane sources most likely driving the increase are from human activities, including agriculture, landfills and waste management, and from the use of coal, oil and gas. These activities are responsible for more than 80% of the rise of atmospheric methane since 2007. The analysis suggests that wetland emissions have not contributed significantly to increases in atmospheric methane, despite continued warming and climate extremes.
A recent paper published in SCIENCE CHINA Earth Sciences presents an improved pDSSAT model based on the Wang-Engel temperature response function and further analyses the spatiotemporal changes in winter wheat phenology in China from 2000 to 2015 and its climatic drivers.
A new systematic review finds that the British food environment actively undermines people’s attempts to lose weight and keep it off, and suggests that even well-designed weight management services will have limited impact on long-term efforts at weight loss and weight loss maintenance if Government does not employ effective policy to address the food environment.
A new technique takes bioprinting — in which an ink of cells is printed, layer by layer, to form a structure — to a whole new, and icy level. Investigators from the Zhang lab at Brigham and Women’s Hospital have developed a technology that they term “cryobioprinting,” a method that uses a bioink embedded with cells to print frozen, complex structures that can be easily stored for later use.
The secret to producing large batches of stem cells more efficiently may lie in the near-zero gravity conditions of space. Scientists at Cedars-Sinai have found that microgravity has the potential to contribute to life-saving advances on Earth by facilitating the rapid mass production of stem cells.
Down near the Earth's core, there are zones where seismic waves slow to a crawl. New research finds that these enigmatic and descriptively-named ultra-low velocity zones are surprisingly layered. Modeling suggests that it’s possible some of these zones are leftovers from the processes that shaped the early Earth—remnants of incomplete mixing like clumps of flour in the bottom of a bowl of batter.
