hubie writes:For several decades there have been various incarnations of the idea of using lasers to zap flying insects, particularly mosquitoes. One of the systems in active development is the Photonic Fence from Intellectual Ventures Laboratory. Researchers from the laboratory recently published their findings on determining the optimal dosage to kill mosquitoes using the least amount of energy. One of the criticisms of their system has been that the areas in greatest need for mosquito eradication provide unreliable power, so their system would most likely need to operate by providing its own power.Their research found that the optimal pulse duration for the lasers they are considering in their design is 25 ms. A significant difference between this research and their previous work is that this study was conducted on in-flight mosquitoes as opposed to previous work that used anesthetized specimens, which demonstrated their vision-based track and targeting system. An added bonus is the four slow-motion videos provided in the Supplemental Information section showing mosquitoes being zapped.Keller, M.D., Norton, B.J., Farrar, D.J. et al.

Given the designs under consideration and that these vehicles would fly above the ozone layer, they considered the effects of water vapor and nitrogen compounds on the ozone layer as a function of the altitude they are released.
HudsonLunatic writes:The 2020 Atlantic hurricane season continues to shatter records with Tropical Storm Beta churning in the Gulf of Mexico. When the normal list of names is exhausted, the Greek alphabet is used for storm names. The 2005 Atlantic hurricane season also went into the Greek alphabet and Beta became a major hurricane with maximum sustained winds of 115 mph at the storm's peak intensity. Hurricane Beta (2005) didn't form until October 26, 2005 making the 2020 season over a month ahead of the pace of the record breaking 2005 season. This raises the conundrum of whether to retire letters of the Greek alphabet if a storm is particularly damaging. It appears the name would not be fully retired but a storm could be retired with a name like "Beta 2020" with the Greek letter remaining in use for future seasons. The extremely active hurricane season can probably be attributed significantly to climate change.Original SubmissionRead more of this story at SoylentNews.
canopic jug writes:David Rosenthal discusses the last 25 years of digital preservation efforts in regards to academic journals. It's a long-standing problem and discontinued journals continue to disappear from the Internet. Paper, microfilm, and microfiche are slow to degrade and are decentralized and distributed. Digital media are quick to disappear and the digital publications are usually only in a single physical place leading to single point of failure. It takes continuous, unbroken effort and money to keep digital publications accessible even if only one person or institution wishes to retain acccess. He goes into the last few decades of academic publishing and how we got here and then brings up 4 points abuot preservation, especially in regards to Open Access publishing.
hubie writes:Homemade and small scale chocolate making has followed an arc similar to the beer industry where a "golden age" declines through consolidation to industrial dominance from which an "artisan" resurgence grows. In the early 20th century there were a relatively large number of chocolate makers where most of them were small-scale producers. As the century progressed, a number of factors drove the industry to consolidate where essentially all the small-scale makers were bought, or they went out of business. The global industry today is dominated by the "big five": Hershey's, Mars, Ferrero Rocher, Cadbury, and Nestlé. However, over the last 15 or so years, a number of small but dedicated "bean to bar" chocolate makers have been springing up.Read more of this story at SoylentNews.

Since the COVID pandemic started many stores have had to count how many people enter and leave the store. Woolworths will introduce customer counting devices to do this task instead of human staff, taking care to avoid the debacle experienced by the TSA by storing the images as blocks to ensure a level of privacy is afforded customers.Can I apply for a job to be a machine?Original SubmissionRead more of this story at SoylentNews.
