Empirical energy consumption model quantifies Bitcoin's carbon footprint
Researchers have conducted the first analysis of Bitcoin power consumption based on empirical data from IPO filings and localization of IP addresses. They found that the cryptocurrency's carbon emissions measure up to those of Kansas City—or a small nation. The study, published June 12 in the journal Joule, suggests that cryptocurrencies contribute to global carbon emissions, an issue that must be considered in climate change mitigation efforts.

'Self-healing' polymer brings perovskite solar tech closer to market
A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells (PSCs), according to scientists from the Okinawa Institute of Science and Technology Graduate University (OIST). Adding a "self-healing" polymer to the top of a PSC can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology.

Wearable device reveals how seals prepare for diving
A wearable non-invasive device based on near-infrared spectroscopy (NIRS) can be used to investigate blood volume and oxygenation patterns in freely diving marine mammals, according to a study publishing June 18 in the open-access journal PLOS Biology by J. Chris McKnight of the University of St. Andrews, and colleagues. The results provide new insights into how voluntarily diving seals distribute blood and manage the oxygen supply to their brains and blubber, yielding important information about the basic physiological patterns associated with diving.

The hunt for hot nuclear matter
In particle physics, a jet is a shower of collimated particles generated by a highly energetic quark or gluon. In a lead-lead collision, jets must traverse through quark gluon plasma, altering their energy, track and consistency.

Witnessing uncivil behavior
Suppose you're at a nice restaurant celebrating your anniversary. When a customer at a nearby table complains that it's taking too long to get his meal, you and your spouse overhear the server's brusque response. Would the server's behavior prompt you to leave a smaller tip for your own meal?
