Dirty laundry in space? NASA, Tide tackle cleaning challenge
CAPE CANAVERAL, Fla. (AP) — How do astronauts do laundry in space? They don’t. They wear their underwear, gym clothes and everything else until they can’t take the filth and stink anymore, then junk them.
FOTW #1190, June 14, 2021: Battery-Electric Vehicles Have Lower Scheduled Maintenance Costs than Other Light-Duty Vehicles
The estimated scheduled maintenance cost for a light-duty battery-electric vehicle (BEV) totals 6.1 cents per mile, while a conventional internal combustion engine vehicle (ICEV) totals 10.1 cents per mile.
California residents urged to conserve energy amid heat wave
LOS ANGELES (AP) — The operator of California's power grid is asking residents to voluntarily conserve power for a few hours Thursday evening as record-breaking heat blankets the West this week. The California Independent System Operator issued a Flex Alert for Thursday from 5 p.m.
What’s not in the news headlines or titles of Alzheimer disease articles? #InMice
This study reveals that when scientists omit from the papers’ title that research findings were obtained using mice, as opposed to humans, the media tend to replicate the trend by omitting the use of mice from the news stories headlines that report on these papers, thereby perpetuating the misleading omission.
Ice-shelf retreat drives recent Pine Island Glacier speedup
Speedup of Pine Island Glacier over the past several decades has made it Antarctica’s largest contributor to sea-level rise. The past speedup is largely due to grounding-line retreat in response to ocean-induced thinning that reduced ice-shelf buttressing. While speeds remained fairly steady from 2009 to late 2017, our Copernicus Sentinel 1A/B–derived velocity data show a >12% speedup over the past 3 years, coincident with a 19-km retreat of the ice shelf. We use an ice-flow model to simulate this loss, finding that accelerated calving can explain the recent speedup, independent of the grounding-line, melt-driven processes responsible for past speedups. If the ice shelf’s rapid retreat continues, it could further destabilize the glacier far sooner than would be expected due to surface- or ocean-melting processes.
Hannah Brenkert-Smith has studied the role of residents' choices in wildfire risk for two decades, with one goal being to improve mitigation programs. Her most recent work near Bailey, Colorado, concludes residents often overestimate their preparation and underestimate their risk.
Artificial intelligence spots coronal holes to automate space weather prediction
Scientists from the University of Graz (Austria), Skoltech and their colleagues from the US and Germany have developed a new neural network that can reliably detect coronal holes from space-based observations. This application paves the way for more reliable space weather predictions and provides valuable information for the study of the solar activity cycle. The paper was published in the journal Astronomy & Astrophysics.
