Nitrous oxide is known as the gas used in whipped cream cartridges or as an anaesthetic in hospitals. But it’s much more than that. This potent greenhouse gas is also released from biological wastewater treatment plants (WWTPs), posing a real threat to our climate. PhD student Nina Roothans (University of Technology, Delft The Netherlands), who recently graduated cum laude, has identified practical strategies to reduce nitrous oxide emissions. Her groundbreaking work has now been published in Nature Water.

It is crucial to effectively regulate the electronic structure of Pt to enhance the CO tolerance in the hydrogen oxidation reaction. Utilizing atomically dispersed W sites to modulate the electronic structure of Pt can optimize the adsorption kinetics of hydrogen and CO, thereby promoting hydrogen oxidation activity and hydrogen-oxygen fuel cell performance even in H₂/CO mixture containing 1000 ppm CO.

Even a few nights with insufficient sleep promote molecular mechanisms linked to a greater risk of heart problems. This has been shown in a new study in which the researchers investigated how sleep deprivation affects biomarkers (in this case proteins) associated with cardiovascular disease. The study was led from Uppsala University and is published in the journal Biomarker Research.

In collisions of argon and scandium atomic nuclei, scientists from the international NA61/SHINE experiment have observed a clear anomaly indicative of a violation of one of the most important symmetries of the quark world: the approximate flavor symmetry between up and down quarks. The existence of the anomaly may be due to hitherto unknown inadequacies in current nuclear collision models, but the potential connection to the long sought-after ‘new physics’ cannot be ruled out.

An international research team including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) Senior Fellow Alexander Kusenko has published a new study suggesting that galaxy NGC 1068 produces neutrinos but weak gamma rays because helium nuclei may be colliding with ultraviolet light near the galaxy's core, breaking apart and releasing neutrons that eventually decay into neutrinos.
