The Indian Navy, like the Indian Air Force and Army Aviation Corps has a significant shortage of pilots, and needs steady interest in its flying wing to justify proposals to buy expensive new jets in the future.
An officer at the Navy’s Goa base told Livefist, “The film being made is pointed directly at the young. When it’s ready, it will be an exhilarating showcase of speed from something that many can’t really relate to — a fighter jet that costs hundreds of crores — to the things they can relate to — a sports car, for instance. The line of the film will be direct too: If you have the passion, if you crave adventure and speed, then look no further than the Indian Navy.”
I wear my contact lenses most days—especially during the summer when I hope to don some fly-ass sunglasses. At the end of every month, my two flexible lenses’ lives are over. Into the bathroom garbage bin they go.
Turns out that one in five users of contacts may be flushing them down the drain or toilet—an ungodly act that exacerbates our plastic pollution problem. That’s according to a not-yet peer-reviewed paper led byresearchers from Arizona State University’s Biodesign Institute’s Center for Environmental Health Engineering. They presented their research at an American Chemical Society meeting Sunday.
Those of the roughly 45 million U.S. contact wearers who throw their lenses down the drain are causing additional plastic to wind up in our sewage system and reach wastewater treatment plants. There, contacts eventually meet their fate as part of the sewage sludge these plants produce. The study authors estimated how many contact lenses end up in our waste by conducting an online survey of about 400 users to figure out what proportion throw them down the drain. They also tested how bacteria found in treatment plants interact with 11 lens polymer types and found that none are particularly biodegradable.
The paper’s abstract, which is all that’s publicly available until the study is accepted into an academic journal, estimates that more than 24,000 pounds of the polymers found in contact lenses end up on U.S. land a year as “biosolids,” or processed sludge, through some form of application like farm fertilizer.
“We’re hoping people will stop flushing their lenses and that that number goes down,” said Rolf Halden, the director of the Center for Environmental Health Engineering who co-authored the paper, to Earther.
The research team worries about these plastics eventually making their way into the food chain through our land-based friends (like worms and birds) and/or our aquatic buds (like mussels and fish). That’s potentially bad news for humans, too, as researchhasshown that plastics can absorb pollutants (like mercury) in the water, causing them to accumulate infish, which may eventually make their way into our bodies when we eat them.
The impact on human health remains to be seen, but this latest research is another warning to humanity to slow down its plastic consumption.
Still, plastics aren’t all we should be worrying about, said Allen Burton, an environmental sciences professor at the University of Michigan who oversees the Environmental Toxicology and Chemistry academic journal, which examines similar research topics. The way he sees it, people also need to be worrying about the threats from excess nutrients and urban runoff, which he sees as a bigger main cause of problems in our aquatic systems.
“In general, yes we need to get rid of plastics,” Burton told Earther. “They are causing huge problems.”
However, he doesn’t want this research to spur the sort of backlash we’ve seen against, say, plastic straws to the points where they’re banned or severely restricted.“Don’t tell me that I need to get rid of my contact lenses,” he said. “They’re not causing a huge problem .”
Of course, Halden and his team aren’t calling for such, but they do hope users quit flushing these plastic lenses down their drains. Microplastics expert Susanne Brander, an assistant professor at Oregon State University, is grateful for these findings. She told Earther she wasn’t surprised by them, but she thinks the public needs as much research on plastics as it can get.
“This study is timely in that it points out that we’ve only scratched the surface when it comes to eliminating [microplastics],” Brander said.
4Pockets have been around a very long time indeed. Back in 2011 I did an interview with 4Pockets when they launched their original version of MeTeoR (Multi-Track Recorder) for Windows Mobile! You can read about it here. A lot has changed since then. In the last few years 4Pockets has been relatively quiet. There have been a few updates to Meteor and Synergy Studio (still a personal fav of mine), but not a great deal that’s new. Now that’s changed. There’s a suite of new audio unit plug ins aimed at improving your sound. Each is a separate app, and, there’s also a bundle deal for all three, details are below. For now, here are the app descriptions.
Audio Expander AUv3 Plugin
This is an AUv3 compatible audio expander which can be used as a plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a graphical interface and presets with stereo metering to monitor signal levels.
The expander can be used to increase the dynamic range of the audio signal by reducing specific bandwidths that fall below a specified threshold. This is essentially the opposite of a compressor and can be used when you have a noisy recording and want to reduce the volume of the quieter parts to reduce noise. Expanders are also great for enhancing drum tracks creating gated effects which give your drum tracks more punch.
Audio Expander costs $4.99 on the app store now
Audio Compressor AUv3 Plugin
This is a AUv3 compatible audio compressor which can be used as plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a modern graphical interface and presets with stereo meters for monitoring signal levels.
Audio Compressor costs $4.99 on the app store now
Parametric EQ AUv3 Plugin
This is an AUv3 compatible stereo parametric equalizer which can be used as a plugin with your favourite DAW such as Cubasis, Meteor, Auria or GarageBand. It supports a graphical interface and presets with stereo metering to monitor signal levels.
Parametric EQ costs $4.99 on the app store now
Finally, the bundle deal includes all 3 plugins and costs just $11.99, which is a pretty good saving.
WasteShark is an aquadrone that can collect waste and swim 8 hours at a time. It is steered by a remote control and it’s movements are tracked via GPS. This aquadrone has customizable sensors that can measure environmental data such as depth, salinity, chemical makeup, pH balance, and temperature. Following is a transcript of the video.
This aquadrone swims through the water to collect waste
WasteShark efficiently collects trash out of rivers, ports, and marinas while simultaneously scanning and collecting water quality data.
Richard Hardiman: So all the platform does really is give us the ability to go autonomously through water and take out stuff that shouldn’t be in there and create a better water environment for everybody."
It can pick up trash close to one foot under the surface.
Hi! You didn’t come here to avoid studying, did you? Well, at least you’ll learn how to study better when you’re done with this little break. These are Lifehacker’s most popular study tips from the last five years.
It’s Freshman Orientation Week at Lifehacker! This week, we’re covering ways to snap out of your summer haze and into an autumnal blitz of activity, whether you’re actually heading to campus for the first time, getting your own kids ready for school, or looking for ways to just be more productive in the classroom of life. So velcro up your Trapper Keepers, students. Class is now in session.
1. Study Less, Study Smart
In an hour-long lecture, psychology professor Dr. Marty Lobdell lays out study techniques and habits. Among them: use a designated study area, study a half hour at a time, and divide what you learn into facts and concepts. (Facts might require tricks or mnemonics to memorize; concepts stick with you.)
2. The Feynman Technique
“Once you can explain an idea in simple language, you have deeply understood it, and will remember it for a long time,” says this two-minute video from the educational YouTube channel Sprouts. In the Feynman Technique, named after the plain-spoken physicist, you study by teaching, or pretending to teach, the material. You know you’ve learned something when you can explain it to a new student.
Richard Feynman was a famously good professor, as he could explain physics simply and entertainingly. Just watch him do it, it’s astounding. Even his lectures are satisfying to read. That’s the promise of the Feynman Technique.
3. Video Game Music
OK, the original post is just an advice animal from Reddit, reading “Looking for good music to work to? Try video game soundtracks. The music’s designed to provide a stimulating background that doesn’t mess with your concentration.”
If you just cannot use a damn index card, here are eight flashcard apps to study with. Some are free, some come with study games, some offer huge packs of pre-written cards. Just, you know, don’t spend an hour picking apps instead of studying.
5. Take Study-Worthy Lecture Notes
This post by Lifehacker founder Gina Trapani dates back to 2006, but thousands of people are still learning from it. Gina explains the Cornell Notetaking Method, which includes layout and conceptual organization. She tells you how to study those notes and links to some template resources. This is some real meaty study advice.
6. Study Before Bed
Another classic post, this one explains the results of a scientific study, which indicates that when you’re studying unfamiliar material, you might get a boost by studying before bed—instead of, say, the morning.
7. Bad Study Habits
“Highlighting and re-reading don’t really help you retain any information. They’re like liking a charity’s page on Facebook: it might look good and make you feel like you’re helping, but in reality it’s a big waste of time.” This Adam Ruins Everything-style video lists bad habits to avoid, then good ones to replace them with.
8. Retain Information
Four tips pulled from some of the methods above, like self-quizzing, visualization, and making metaphors to understand concepts.
9. Classical Music Study Playlist
Classical music is a great study genre, if you know what pieces to pick. You don’t want Beethoven’s Fifth. That’s why we love this six-hour playlist curated by classical record label NAXOS.
10. Study Tips
Educational YouTube channel AsapSCIENCE gives study tips based on science, like “make your own flashcards” and “make practice tests.”
11. The Case for Silence
The best study music might be no music, according to scientific research. Subjects performed better on demanding cognitive tasks without music or background noise. For less demanding tasks, music can help. But for a particularly tough topic, see how long you can study in silence without getting bored.
