Hubble discovers that dwarf planet Makemake has a moon

The Hubble telescope has spotted a shadowy moon with a charcoal black surface orbiting the dwarf planet Makemake. Astronomers first observed Makemake in 2005, but since it’s the second brightest icy dwarf planet after Pluto , it took some time to see a satellite that’s 1, 300 times fainter than the celestial body it’s orbiting. Also, it’s positively tiny with a diameter measuring 100 miles across, making it but a fraction of our own moon that has a diameter measuring 2, 159.2 miles. The Hubble team used the telescope’s Wide Field Camera 3 and the same technique that found Pluto’s satellite’s in 2005, 2011 and 2012 to discover Makemake’s companion that has been christened “MK 2.” NASA says its presence can tell us more about the dwarf planet, including its density. “Makemake is in the class of rare Pluto-like objects, so finding a companion is important, ” Southwest Research Institute’s Alex Parker said. “The discovery of this moon has given us an opportunity to study Makemake in far greater detail than we ever would have been able to without the companion.” Astronomers plan to look more closely into the satellite to find out if it’s the “warm region” they’ve been seeing on Makemake’s surface, which is inconsistent with its icy shell. They also intend to observe its movements: a tight orbit means it’s the product of a collision, while a wide one means it was captured from the Kuiper belt. Either way, MK 2 — just like our Earth’s own satellite — has been orbiting Makemake for billions of years. Via: Space Source: Space Telescope Science Institute , NASA

J&J’s anesthesia-bot loses against its human counterparts

Just because robots can be more efficient than humans and can make certain processes cheaper doesn’t mean they’ll always come out on top. Case in point: Johnson & Johnson is pulling its anesthesia robot called Sedasys from the market over poor sales, according to Outpatient Surgery and Anesthesiology News . It was once a promising alternative to anesthesiologists, since it can bring down the cost of administering sedation from $2, 000 per procedure to $150 to $200. It eliminates the need for an anesthesia professional, after all, as it allows any nurse or doctor to put a patient under in the operating room. One of the reasons why it experienced such slow adoption rates is because the American Society of Anesthesiologists campaigned against it. The group eventually backed down after the machine was limited for use in routine procedures like colonoscopy, but by then, they’ve already done their job. Unfortunately, J&J now plans to lay off 3, 000 employees from its medical devices division due to its products’ (Sedasys included) poor sales, so it’s not a total victory for humans after all.

AT&T gets ready to test 5G technologies this 2016

AT&T has been working on possible 5G technologies, such as millimeter waves, for years. Now that it’s time to get serious, it’s teaming up with Ericsson and Intel to ramp up its development in the lab in the second quarter of the year. After that, it’s moving its 5G endeavors out of the lab and into the field, starting with outdoor tests over the summer. The carrier says 60 percent of its mobile traffic in 2015 came from video. It’s moving forward with its 5G plans, because emerging technologies like virtual reality, 4K video, robots, Internet of Things and self-driving cars will be even more demanding. As AT&T’s Chief Strategy Officer John Donovan notes, those technologies “will be immersive, pervasive and responsive to customers. 5G will help make them a reality.” 5G internet could be anywhere from 10 to 100 times faster than LTE, with users observing downloads going gigabits (yes, giga bits) per second. Imagine being able to finish downloading a TV show for less than three seconds. That’s nowhere near enough time to get up and microwave some popcorn. AT&T believes its 5G network will even be able to start streaming videos much, much faster — just 1 to 5 milliseconds from the moment you press play — than an LTE connection. If everything goes well, some parts of Austin, Texas will be able to test out Ma Bell’s 5G tech by the end of this year. The company says it’s conducting tests in a way that enables it to deploy the network commercially as soon as 5G standards are set. You’d have to wait a while for that to happen, though. 3GPP, the international consortium in charge of hashing out network standards, is working on it right now. However, phase one (of two) won’t be completed until the first half of 2018. By the way, AT&T isn’t the only US carrier gearing up to test its next-gen mobile network: Verizon will soon begin its 5G wireless service trials, as well.

US Customs seize 16,000 counterfeit ‘hoverboards’

The US Customs and Border Protection has prevented 16, 000 counterfeit “hoverboards” from making it to people’s homes. Authorities have seized a warehouse full of the controversial two-wheeled scooters stamped with fake trademark logos and equipped with unauthorized batteries in Chicago. They believe the goods they collected amount to $6 million overall, at least for now. That figure will grow even bigger, since the warehouse is expecting a “massive amount of shipments” to arrive in the next few weeks. These self-balancing scooters became a huge hit last year, so numerous questionable manufacturers took advantage of the craze and released subpar, non-quality controlled versions to stores. They’ve been all over the news in the past few months for spontaneously catching fire and burning people’s houses down. At least one incident took place in Illinois. Due to the hazard inferior-quality hoverboards pose, the scooters had been banned from many airplanes , universities and even from NYC’s trains and buses . Last year, UK authorities also seized 15, 000 units after inspecting shipments at seaports and airports. [Image credit: US Customs/Flickr ] Via: Mashable Source: US Customs and Border Protection

Lyft will pay $12.25 million to settle drivers’ lawsuit in CA

One company is done battling a gig economy -related lawsuit, at least in California. Lyft has agreed to grant its drivers more workplace protection and to pay $12.5 million to settle a proposed class action lawsuit. The California drivers who filed the lawsuit against the company wanted to be reclassified as employees in order to receive minimum wage and benefits, as well as to get Lyft to pay for their gas and vehicle maintenance. While they’ve unfortunately failed to get their status changed — they’re still considered contractors — drivers in the state will get part of the settlement fund based on the hours they’ve put into working for the company. Lyft also can’t drop drivers whenever it wants. The company can only terminate someone based on a number of predetermined reasons, such as low passenger ratings. Even then, the driver will be given the chance to air their side of the story. Finally, drivers who consistently get high ratings and who passengers pinpoint as their favorites will be rewarded with bonuses. Jackdaw Research chief analyst Jan Dawson told Reuters that while Lyft is losing millions, it still got off “fairly lightly.” Reclassifying drivers as employees, he said, would have cost the company much, much more. Uber wasn’t able to prevent a similar case from becoming a full-fledged class action lawsuit, but this proves it’s possible to settle with the plaintiffs without changing how the company operates.

NASA’s FireSat system will be able to detect wildfires from space

NASA’s Jet Propulsion Laboratory and San Francisco-based company Quadra Pi R2E are developing a space-based wildfire detector that can keep an eye on the whole world. This system, called FireSat, will be made up of over 200 thermal infrared imaging sensors installed on satellites in low-Earth orbit. It will be powerful enough to detect wildfires 35 to 50 feet wide within 15 minutes from the time they begin. And since wildfires spread very quickly , it will have the capability to contact authorities, so they can send emergency responders to the scene as early as possible. Source: NASA

A startup is growing faux shrimp meat in the lab using algae

Someday, you might be able to throw a lab-grown meat party with not only burgers , but also tempura on the menu. A startup called New Wave Foods is developing artificial shrimp meat in the laboratory, urged by environmental destruction and the other troubles brought about by commercial fishing. According to Motherboard , the team is currently testing different ways of extracting proteins from algae that the crustaceans eat, mixing and mashing them together with protein gels to create the meat. So far, they’ve already nailed the taste, but mimicking the seafood’s texture is proving to a bit more difficult. Source: Motherboard , New Wave Foods

Cassini gets cozy with Saturn’s moon, flies 30 miles above its surface

Cassini has just finished the second of three planned Enceladus flybys on October 28th, going as close at 30 miles above the surface of the icy moon’s south polar region. The photo above was taken after the flyby, showing both the moon and Saturn’s rings, but rest assured the probe took a lot of close-up photos. It even grabbed some of the gas and dust that erupted from one of Enceladus’ geysers that typically spew water and other materials up to 125 miles into the sky. NASA will analyze those samples within the next few weeks, which should gives us more details about the composition of the moon’s ocean floor, as well as about any underwater hydrothermal activity. Cassini made the first flyby this early October to take a closer look at Enceladus’ north pole region. It’s scheduled to make its last one on December 19th to measure the heat the moon gives of, after which it’ll move on to other things for the last two years of its life. Source: NASA

Google’s driverless cars skirt deer and pedestrians in Texas

By the looks of things, Google’s self-driving cars have been learning a lot in Austin, Texas . In its first report since it began testing autonomous vehicles in the city, the company details the challenges its cars have had to face while driving on its roads. For instance, they’ve been spotting and avoiding a lot of deer, some of which might have ended up as road kill if they happened to come across ordinary vehicles instead. The system also had to learn to identify new infrastructure, such as horizontal traffic signals. Google has learned, however, that one of the major problems it has to tackle is pedestrians stepping off the curb onto the road while hidden by other vehicles. On August 20th, a Lexus unit was rear ended after spotting a person starting to cross the road. See, its human driver took over to make sure he doesn’t end up harming anyone, but it turns out — based on the footage of the incident — that the accident wouldn’t have happened if he just allowed the car to brake on its own. Clearly, Google’s doing what it can to achieve its original goal of developing autonomous vehicles that can drive better than humans. In addition to discussing what it has learned in Austin, Mountain View has also revealed through the report that it’s deploying more of its egg-like prototype models in the city this September.

Google expands health conditions feature to over 900 illnesses

Google’s health conditions feature is about making it easier to find information about an illness. So, when there’s a local outbreak, or you get early symptoms, you can be better prepared. Mountain View has doubled the number of diseases in its database, bringing the number up to over 900 — including neglected tropical diseases and infections that typically affect people in developing nations. If you do a query for any of those illnesses on either mobile or desktop, you’ll see a quick results panel, which contains info on its symptoms, treatments and prevalence. You can even download the panel as a PDF file that you can print — apparently, that’s the most requested feature among the doctors Google worked with to ensure each condition’s accuracy. Unfortunately, the feature remains accessible only via Google US (that’s Google.com, or the one without a country-specific domain), but the company promises to make it available in more languages in the future.
