YouTube Will Prompt You to Reword Potentially Offensive Comments

YouTube creators love to connect with their audience through the platform’s comments section, but it’s not much fun when posts left by viewers are offensive, bullying, or just plain nasty.

YouTube has implemented various measures over the years to try to ensure such comments stay off its video-sharing platform, or at least get pushed down the list to reduce visibility, but this week it’s launching a new feature aimed at encouraging people to think twice before posting a potentially offensive comment.

It means that when YouTube’s algorithms detect a such a comment, it’ll issue a note to the poster saying, “Keep comments respectful,” adding, “If you’re not sure whether your comment is appropriate, review our Community Guidelines.” It also asks the poster to let YouTube know if they think its algorithm has made a mistake in singling out the comment as potentially offensive. Indeed, YouTube notes that its computer systems

UBER driver data helps track and potentially alleviate urban traffic congestion — ScienceDaily

A new machine learning algorithm is poised to help urban transportation analysts relieve bottlenecks and chokepoints that routinely snarl city traffic.

The tool, called TranSEC, was developed at the U.S. Department of Energy’s Pacific Northwest National Laboratory to help urban traffic engineers get access to actionable information about traffic patterns in their cities.

Currently, publicly available traffic information at the street level is sparse and incomplete. Traffic engineers generally have relied on isolated traffic counts, collision statistics and speed data to determine roadway conditions. The new tool uses traffic datasets collected from UBER drivers and other publicly available traffic sensor data to map street-level traffic flow over time. It creates a big picture of city traffic using machine learning tools and the computing resources available at a national laboratory.

“What’s novel here is the street level estimation over a large metropolitan area,” said Arif Khan, a PNNL computer scientist who

We Have No Idea What Makes A Planet ‘Potentially Habitable’

One of the most compelling scientific goals humanity has set for itself is to find extraterrestrial life: biological activity originating and continuing to occur on a world beyond Earth. It isn’t just our imaginations that have run wild with this possibility, it’s that we have a lot of indirect evidence identifying other potential locations where life could have arisen through similar processes to whatever occurred on Earth in our past. If we compare what’s out there with our expectations for what life requires, there’s a lot that appears to make sense.

One Way To Potentially Improve Your Returns

There are many ways to improve your investing performance. However, sometime the low-hanging fruit doesn’t require any investing skill. This can include being tax-aware with your investing approach or simply considering how you place orders. Research suggests that using limit orders can often improve your investing outcomes, even if you’ll miss out on some trades.

What Academics Have Found

The key as researchers Lawrence Harris and Joel Hasbrouck wrote in a 1996 paper is that, “Market orders pay an implicit price for immediacy.” Yes, if you absolutely have to trade right now, then a market order it is necessary because it will be filled.

However, you are typically paying a premium for that certainty of execution. If the trade isn’t essential or you have a bit of patience, then limit orders are often the better strategy.

Now, of course, using limit orders won’t transform your investment performance overnight,

About half of Sun-like stars could host rocky, potentially habitable planets — ScienceDaily

Since astronomers confirmed the presence of planets beyond our solar system, called exoplanets, humanity has wondered how many could harbor life. Now, we’re one step closer to finding an answer. According to new research using data from NASA’s retired planet-hunting mission, the Kepler space telescope, about half the stars similar in temperature to our Sun could have a rocky planet capable of supporting liquid water on its surface.

Our galaxy holds at least an estimated 300 million of these potentially habitable worlds, based on even the most conservative interpretation of the results in a new study to be published in The Astronomical Journal. Some of these exoplanets could even be our interstellar neighbors, with at least four potentially within 30 light-years of our Sun and the closest likely to be at most about 20 light-years from us. These are the minimum numbers of such planets based on the most

Our galaxy holds at least 300 million potentially habitable planets, NASA finds

Our galaxy is filled with potentially habitable planets — at least 300 million of them, according to NASA.

After nine years in deep space collecting data that revealed our night sky to be filled with billions of hidden planets -- more planets even than stars -- NASA's Kepler space telescope ran out of fuel needed for further science operations in 2018.

An illustration representing the legacy of NASA’s Kepler space telescope. After nine years in deep space collecting data that revealed our night sky to be filled with billions of hidden planets — more planets even than stars — NASA’s Kepler space telescope ran out of fuel needed for further science operations in 2018.

The US space agency’s Kepler Space Telescope spent nine years on a planet-hunting mission, successfully identifying thousands of exoplanets in our galaxy before running out of fuel in 2018. But the original mission’s core question remained: how many of these planets are habitable?

SpaceX will stream potentially fireworks-filled Starship test flight


SpaceX assembled the shiny pieces of its planned Starship orbital prototype in late 2019. This wasn’t a launch-ready version, but it shows what the spacecraft will probably look like when it’s finally ready for testing.


The latest prototype of Elon Musk’s planned Mars rocket has been coming together at the SpaceX development facility in Boca Chica, Texas. SN8 looks more like an actual rocket than previous iterations, and it could be the first to make an actual high altitude flight, though Musk has been quick to lower expectations.

Previous versions have managed a few short “hops” of nearly 500 feet (150 meters) in altitude before making controlled landings not far from where they lifted off. Now Musk hopes to fly SN8 to over 9 miles (15 kilometers) high, but he also isn’t guaranteeing it’ll make it far off the launchpad.

New method could potentially reduce dioxide emission into the atmosphere and slash costs of chemical manufacturing — ScienceDaily

Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have demonstrated a room-temperature method that could significantly reduce carbon dioxide levels in fossil-fuel power plant exhaust, one of the main sources of carbon emissions in the atmosphere.

Although the researchers demonstrated this method in a small-scale, highly controlled environment with dimensions of just nanometers (billionths of a meter), they have already come up with concepts for scaling up the method and making it practical for real-world applications.

In addition to offering a potential new way of mitigating the effects of climate change, the chemical process employed by the scientists also could reduce costs and energy requirements for producing liquid hydrocarbons and other chemicals used by industry. That’s because the method’s byproducts include the building blocks for synthesizing methane, ethanol and other carbon-based compounds used in industrial processing.

The team tapped a novel energy source from the

Potentially raising risk of neurological damage in COVID-19 patients — ScienceDaily

Like a key, SARS-CoV-2 — the virus that causes coronavirus disease 2019 (COVID-19) — attaches to specific molecules on the host cell surface, opening gateways into the cell interior. Viral entry into host cells triggers a prodigious immune response. Much of this battle is waged within the lungs, which explains why many patients hospitalized with COVID-19 have severe respiratory symptoms.

Respiratory symptoms, however, are only part of the story. Increasing evidence points toward blood vessel inflammation as having a crucial impact on the severity of COVID-19. In addition, anywhere from 30 to 80 percent of patients experience neurological symptoms, including dizziness, headache, nausea, and loss of concentration. These symptoms suggest that SARS-CoV-2 also affects cells of the central nervous system.

While there is no evidence yet that the virus invades the brain, new work by scientists at the Lewis Katz School of Medicine at Temple University shows that the spike

34% of older adults in the US are prescribed potentially inappropriate drugs — ScienceDaily

The prescription of potentially inappropriate medications to older adults is linked to increased hospitalizations, and it costs patients, on average, more than $450 per year, according to a new University at Buffalo study.

The research, which sought to determine the impact of potentially inappropriate medications on health care utilization and costs in the United States, also found that more than 34% of adults age 65 and older were prescribed these problematic drugs.

“Although efforts to de-prescribe have increased significantly over the last decade, potentially inappropriate medications continue to be prescribed at a high rate among older adults in the United States,” says David Jacobs, PharmD, PhD, lead investigator and assistant professor of pharmacy practice in the UB School of Pharmacy and Pharmaceutical Sciences.

Collin Clark, PharmD, first author on the paper and clinical assistant professor in the School of Pharmacy and Pharmaceutical Sciences, adds, “The average age of the U.S.
