In the title compound, C16H14Cl2FN3, the dihedral angle between the two aromatic rings is 64.12 (14)°. The crystal structure is stabilized by a short Cl...H contact, C—Cl...π and van der Waals interactions. The Hirshfeld surface analysis and two-dimensional fingerprint plots show that H...H (33.3%), Cl...H/H...Cl (22.9%) and C...H/H...C (15.5%) interactions are the most important contributors towards the crystal packing.

Harris Wittels, a comedy writer who worked on "Parks & Recreation," has died at 30, the Los Angeles Police Department's Jane Kim tells KPCC.

Wittels was discovered by his assistant around 12 p.m., Kim said, and was already dead. Kim said that Wittels' death was a possible overdose, but that the Coroner's Office would determine the cause of death. Wittels had attended drug rehab twice.

Comedy Central, where Wittels worked on "The Sarah Silverman Program" and "Secret Girlfriend," confirmed Wittels' death, as did the comedy show he appeared at Wednesday night.

Wittels was also well known for his @Humblebrag Twitter account and later book, helping to popularize the idea online of the false modesty of bragging while trying not to look like you're bragging.

Wittels had spoken about his struggles with addiction in places including Pete Holmes's podcast "You Made It Weird" in a November episode.

"I just really stopped caring about my life," Wittels said on "You Made It Weird," explaining how he got into doing drugs. "I just really started to think, well, if I'm only here for 80 years, then who cares if I spend it high or not?"

Wittels received his first big break when Sarah Silverman saw him performing comedy and gave him a job writing for her Comedy Central show.

Wittels also wrote for HBO's "Eastbound & Down," several MTV awards shows and the American Music Awards. He had a recurring role on "Parks & Recreation" and was a regular guest on the "Comedy Bang Bang" podcast.

Comedians, actors and fans mourned Wittels' death online.

(The Paypers) A new survey suggests the majority of Canadians remain worried about the security of their personal information online.

A preponderance of scientific evidence shows that even low doses of ionizing radiation, such as gamma rays and X-rays, are likely to pose some risk of adverse health effects, says a new report from the National Academies National Research Council.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome -- commonly referred to as ME/CFS -- is a legitimate, serious, and complex systemic disease that frequently and dramatically limits the activities of affected individuals, says a new report from the Institute of Medicine.

Cardiac arrest strikes almost 600,000 people each year, killing the vast majority of those individuals, says a new report from the Institute of Medicine. Every year in the U.S., approximately 395,000 cases of cardiac arrest occur outside of a hospital setting, in which less than 6 percent survive.

In just a few years, digital technologies have allowed faster mobilization in response to humanitarian crises, better documentation of war crimes in conflict zones like Syria and Yemen, and more accessible platforms for organizing peaceful demonstrations around the world.

The National Academies of Sciences, Engineering, and Medicine have been awarded a grant for $100,000 from Arcadia — a charitable fund of Lisbet Rausing and Peter Baldwin — to support the work of the Academies’ Roundtable on Aligning Incentives for Open Science.

Here’s another version of those capris – these are a lace print from H&M – and while I’ve seen women wearing them with high heels, it just doesn’t seem right somehow. It so sullies the legacies of Mary Tyler Moore and Audrey Hepburn to pair them with anything but flats!

This is my version of a cutaway coat. In a coat like this I could attend Royal Ascot, or invent the telegraph. Obviously it’s a girl version, but I feel empowered, even … princely. At least Fred Astaire-ish. Maybe a pair of spats would make me feel more so. And I could waltz facing forward, not dancing backward, a la Ginger.

As for the adornments, I am not a hearts-and-butterflies kind of girl, but I do like to wear themed brooches in clusters or multiples, and this pair of hearts – just like a poker hand – seemed to work. One is the arrow-pierced one [not to be confused with the Pierce-Arrow, one of the handsomest motorcars ever made].

And the other, the enormous bogus diamond heart, I got from Butler & Wilson, the imaginative London costume jewelry [or better yet ‘jewellery’] designer. It’s my homage to a recent auction of what may be the largest perfect diamond in the world, 101.73 carats.

Harry Winston, the legendary jeweler, bought it for nearly $24 million and has chosen to call it, I am sorry to say, the “Harry Legacy,” which is not the kind of name a diamond like this deserves, one redolent of romance and myth, like “the Hope Diamond” or “the Koh-I-Noor Diamond.”

If you have any suggestions about what to name this magnificent perfect diamond, I’d love to hear them.

My own faux diamond’s name, I have decided, is “The Rhinestone Corazon.” How do you like it?

Scientists have produced a list of seafloor characteristics to determine the health status of the ecosystem it supports. These indicators could improve the quality and consistency of marine conservation efforts across Europe, particularly where the impact of human activities is high.

A standardised method to help choose the most cost-effective measures to remediate contaminated sites has been developed by Austrian researchers. The method takes into account a wide range of factors, including the principles of sustainability.

Increasing noise levels are a global environmental concern, and have been linked to important health issues, such as heart disease and cognitive development. New Danish research has now shown that it is also associated with an increased risk of diabetes.

As the media environment changes, the way scientists communicate their work must also evolve. This study explored the effect of public communication on the scientific ‘impact’ of America’s most highly cited nanotechnology researchers. It provides the first evidence that outreach activities, such as speaking to journalists and being mentioned on Twitter, can increase a scientist’s impact.

The pressures facing Indian manufacturers to ‘green’ their supply chain have been explored by a recent study. Both international and national pressures from government and consumers were found to play an important role in whether a company adopts green supply chain management principles, with pressures varying to some degree depending on the business’s sector and size.

The Alang-Sosiya shipbreaking yard in India is highly polluted with heavy metals, a study concludes. The researchers studied heavy metal contamination in sediments taken from the intertidal zone of the shipbreaking yard and compared them to a control site. The area was found to be ‘strongly polluted’ with copper, cobalt, manganese, lead and zinc.

A study has evaluated three types of media campaign conducted by a large UK supermarket to encourage shoppers to reduce their food waste. These used social media, an e-newsletter and a print/digital magazine, respectively. Although they all appeared to lead to reductions in food waste to some extent, similar behavioural changes were also seen for customers who had not participated in any of the campaigns.

India saw a 62 per cent decline in job hiring in the month of April, led by hotel/restaurant/travel/airlines industries that saw a massive -90 per cent less hiring activity that the same month last year.

Sixty-four per cent of organizations in India and Europe invested in cloud technologies in the last two years, followed by IoT, where 51% firms made investments.

As Indian firms realign their focus on revenue growth, they need to leverage customer and market behaviour to place their bets on long-term, sustainable growth, a new report said.

The headcount has now come down from more than 1,000 employees a year ago, with the majority of job cuts in the wake of Covid-19 outbreak that forced shutdowns in the February-April period. The headcount comprises staff on the company’s rolls as well as those on contract and outsourced manpower.

Monitored natural attenuation (MNA) is a long-term, ‘hands-off’ approach to cleaning up contaminated land. New research has surveyed the current development of MNA in Europe and demonstrates a clear need for practitioners to systematically collect and learn from each other’s experiences with this form of brownfield remediation.

Compared with traditional remediation techniques used to remediate brownfield sites, supporters of phytoremediation argue that it is cheaper and more environmentally-friendly. A new analysis has reviewed its strengths, weaknesses, opportunities and threats, and suggests it is well suited to cleaning up sites with low to medium levels of contamination.
