“We have developed a method to convert polyolefin waste, which include Type 2 (HDPE), Type 4 (LDPE and LLDPE), and Type 5 (PP), into various useful products,” Nien-Hwa Linda Wang, a professor in Purdue’s Davidson School of Chemical Engineering, told Digital Trends. “The conversion is achieved using subcritical or supercritical water, which can convert plastic waste into oil, fuels, or gas, depending on the processing conditions. Some impurities in the plastic waste is converted into oil or extracted into the processing water. Both conversion and extraction are achieved in the same process.”

Late Tuesday night, scientists at NASA’s Jet Propulsion Laboratory sent their final data uplink to the Opportunity rover on Mars. Over this connection, via the Deep Space Network, the American jazz singer Billie Holiday crooned “I’ll Be Seeing You,” a song that closes with the lines:
I’ll find you in the morning sun
And when the night is new
I’ll be looking at the moon
But I’ll be seeing you
The scientists waited to hear some response from their long-silent rover, which had been engulfed in a global dust storm last June, likely coating its solar panels in a fatal layer of dust. Since then, the team of scientists and engineers has sent more than 835 commands, hoping the rover will wake up from its long slumber—that perhaps winds on Mars might have blown off some of the dust that covered the panels.
So on Tuesday night, they listened. They reminisced. But in the end, no response came. Opportunity would finally be declared dead on Sol 5352, as in five thousand, three hundred, and fifty-two days on Mars. NASA is expected to make it official at 2pm ET Wednesday, when NASA Administrator Jim Bridenstine and the chief of the agency’s science division, Thomas Zurbuchen, convene a news conference.
Opportunity landed on Mars more than 15 Earth years ago, on January 25, 2004. So much time has passed since then. Facebook would not be created until a month later. YouTube would not get its first video upload for more than a year. George W. Bush was still in his first presidential term. NASA’s Cassini spacecraft had not yet even arrived in the Saturn system.
And yet from that moment on, Opportunity and its sister rover Spirit began plugging along the surface of Mars. Originally designed for 90-day lifetimes, the rovers persisted. Spirit lasted until 2010, when its batteries were unable to keep the spacecraft’s critical components from freezing.

Two men wearing MAGA (Make America Great Again) caps attacked Empire star Jussie Smollett in Chicago this morning and while calling him homophobic names, racial slurs, and shouting that this is MAGA country, they beat him, broke his ribs, put a noose around his neck, and tried to pour bleach down his throat. These masked assailants are still at large. The increase in hate crimes, mass murders, and racial divides since President Trump took office to “Make America Great Again” is not very “great” at all. These actions represent the worst of America and humankind. Our thoughts and prayers go out to Jussie, an innocent actor, and his family for his full recovery from this horrible hateful crime.

The Food and Drug Administration is sacrificing American lives by continuing to approve new high-strength opioidpainkillers, and manipulating the process in favor of big pharma, according to the chair of the agency’s own opioid advisory committee.
Dr Raeford Brown told the Guardian there is “a war” within the FDA as officials in charge of opioid policy have “failed to learn the lessons” of the epidemic that has killed hundreds of thousands of people over the past 20 years and continues to claim about 150 lives a day.
Brown accused the agency of putting the interests of narcotics manufacturers ahead of public health, most recently by approving a “terrible drug”, Dsuvia, in a process he alleged was manipulated.
“They should stop considering any new opioid evaluation,” said Brown. “For every day and every week and every month that the FDA don’t do the right thing, people drop dead on the streets. What they do has a direct impact on the mortality rate from opioids in this country.”
Brown, an anesthesiologist who chairs the FDA committee of specialists advising the agency on whether to approve new opioid painkillers, said he no longer had confidence in repeated assurances by the FDA leadership that it was taking the epidemic seriously and prepared to put public health above the commercial interests of drug makers.
“I think that the FDA has learned nothing. The modus operandi of the agency is that they talk a good game and then nothing happens. Working directly with the agency for the last five years, as I sit and listen to them in meetings, all I can think about is the clock ticking and how many people are dying every moment that they’re not doing anything,” he said. “The lack of insight that continues to be exhibited by the agency is in many ways a willful blindness that borders on the criminal.”

A California judge has ruled that American cops can’t force people to unlock a mobile phone with their face or finger. The ruling goes further to protect people’s private lives from government searches than any before and is being hailed as a potentially landmark decision.
