The deep sea is far away and hard to envision. If imagined it seems like a cold and hostile place. However, this remote habitat is directly connected to our lives, as it forms an important part of the global carbon cycle. Also, the deep seafloor is, in many places, covered with polymetallic nodules and crusts that arouse economic interest. There is a lack of clear standards to regulate their mining and set binding thresholds for the impact on the organisms living in affected areas.
Mining can reduce microbial carbon cycling, while animals are less affected
An international team of scientists around Tanja Stratmann from the Max Planck Institute for Marine Microbiology in Bremen, Germany, and Utrecht University, the Netherlands, and Daniëlle de Jonge from Heriot-Watt University in Edinburgh, Scotland, has investigated the food web of the deep seafloor to see how it is affected by disturbances such as those caused

Although Prime Day has not yet officially arrived, some early Prime Day deals have already begun to roll in. The event officially starts on October 13, but if you’re in the market for something and see a great deal, go ahead and snag it. Products are likely to sell out quickly, especially on the really great Prime Day smart home deals.
Amazon has dropped the price of the Arlo Pro 3 home security camera system down to $400 for a total savings of $100. This package includes two wireless security cameras that can be mounted nearly anywhere inside or outside of your home.
The Arlo Pro 3 packs some impressive specs inside a small package. The camera has 2K HDR video, which means you can make out details even in areas of high contrast. Digital zoom
Analysts suggest Apple is on the cusp of launching its latest generation of superphone, with an event announced for Oct. 13 (you can livestream Apple’s event from home — here’s how to watch). The current hottest rumors suggest that we may see multiple versions of the iPhone 12, with features like 5G, lidar depth mapping and the latest A14 Bionic processor. (And here are some features on our iPhone 12 wish list that Apple should steal from Samsung.) But what will the phone look like? Let’s dive into the rumor mill to work it out.
North Korea showcased a series of new weapons at its 75th anniversary military parade marking the founding of the ruling Workers’ Party Saturday, including what South Korea officials say was a new intercontinental ballistic missile (ICBM).
North Korea has not broadcast a live military parade on television since 2017, when leader Kim Jong Un heightened U.S. tensions by showing off several large ICBMs. The country showed off its “new strategic weapon,” which analysts described as a much larger, liquid fuel ICBM complete with an 11 axle transporter erector launcher.
The first hint of the new weapon came earlier this week when South Korean officials relayed surveillance of thousands of North Korean soldiers in march formation as they displayed what was possibly a new
Running back Khalil Herbert made his presence felt in the quarter as well with a 52-yard touchdown run. Herbert converted the third and eight by weaving his way through the secondary to go over 100-yards for the third straight game.

The Hokies held onto the ball for nearly 11 minutes in the third quarter, but still couldn’t overcome the 21 points they spotted UNC in the first quarter.
North Carolina went straight down the field on their first three possessions to take a 21-0 lead while averaging 9.7 yards per play.
Howell was near perfect in the quarter going 10 of 12 for 123 yards with a 37-yard touchdown pass to Brown. Brown, who beat Tech cornerback Armani Chatman down the field, was able to get one foot down at the back of the end zone for the score.
WASHINGTON — NASA is delaying the launch of the first operational SpaceX commercial crew mission to the first half of November to provide more time to review a problem during a recent Falcon 9 launch attempt.
NASA announced Oct. 10 the Crew-1 mission, which was scheduled to launch on a Falcon 9 in the early morning hours of Oct. 31 from the Kennedy Space Center, will now launch no earlier than early to mid-November.
The delay, the agency said, will provide more time for SpaceX “to complete hardware testing and data reviews as the company evaluates off-nominal behavior of Falcon 9 first stage engine gas generators observed during a recent non-NASA mission launch attempt.” NASA did not identify the specific launch attempt in question, but an Oct. 2 launch of a Falcon 9 carrying a GPS 3 satellite was scrubbed just two seconds before liftoff because of SpaceX Chief Executive
Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena. Targeting this enzyme may help control plant parasitism in crops. Also, this mechanism can be exploited for novel cross-species grafting techniques to realize the goal of sustainable agricultural technologies.
Plant parasitism is a phenomenon by which the parasite plant latches onto and absorbs water and nutrients from a second host plant, with the help of a specialized organ called the “haustorium.” Once the haustorium forms, specific enzymes then help in forming a connection between the tissues of the parasite and host plants, known as a “xylem bridge,” which facilitates the transport of water and nutrients from the host to the parasite.
It was only nine years ago that the first won’t-break-the-bank electric cars arrived.
Those non-Tesla EVs — like the Nissan Leaf and Chevy Volt — weren’t priced at $80,000 like the Model S and the first- and second- generations of those cars have been hitting the used car market over the last several years.
And with a Long Range 2020 Tesla Model 3 starting at about $47,000, “dirt cheap” for an EV is anything under $20,000.
A couple of the better sites for used EVs are MYEV and CarGurus.
Most of the used EVs cited below are first- and second-generation electrics that were sold roughly between 2011 and 2017.
