Though Johnson  &  Johnson and Purdue Pharma are on the hook for big judgments due to their marketing practices related to opioids, claims that they "created" an opioid epidemic are the scientific equivalent of fat shaming people if you don't like Burger King commercials.

Attorneys will claim it, they will get thousands of people to sign up as litigants, and juries will agree with the emotional arguments they hear, but that has nothing to do with science or health. In appeals cases, science data is used, which is why so many spectacularly ridiculous judgments (like baby powder or a weedkiller magically causing cancer) get overturned.
In America, some groups tell us expiration dates on food are just a conservative guideline while other groups insist that if someone buys expired food the merchant should go to jail. In Europe it can be even more strange, they once tried to ban ugly fruit from being sold because it would likely be purchased by poor people,

If you are a believer in the precautionary principle over all, you buy armloads of organic food at the farmer's market on Saturday, ingest herbs and supplements to promote probiotic health, and religiously obey expiration dates, your refrigerator is probably where food goes to die.
If you believe in medieval accounts of wine harvest dates, Burgundy grapes are in crisis. A new look at dates of grape harvest from the last 664 years says wine grapes in Burgundy, eastern France, have been picked 13 days earlier on average since 1988 than they were in the previous six centuries, and that is due to the region's hotter and drier climate in recent years. 

How accurate that is beyond the last 30 years is unclear.
If you never care about Haiti until a hurricane hits, are you really altruistic or did you instead imagine how others will perceive your actions? Can altruism even exist or does it all come down to social exchange?

When people see someone in distress, neural pathways in the brain create facets of imagination that allow people to see the episode as it unfolds, finds a recent paper. That "episodic simulation", essentially the ability of individuals to re-organize memories from the past into a newly-imagined event simulated in the mindmay help them envision how to aid those in need.
Millennials, the first "Net Generation," say they can use many technologies simultaneously, masterfully switching from emails to instant messaging, app notifications, RSS feeds, and rants on Twitter much better than older generations.

Maybe they can. Generation Z certainly can.

A new study simulated a typical working environment, complete with technology interruptions, to allow scholars to track the effects on participants' inhibitory processes. College-age participants (naturally) totaling and a few other folks totaling 177 were divided into three groups: those who received IT interruptions; those who did not, and a control group. 
Discovery of a "remarkably complete" cranium  (MRD-VP-1/1, shortened to MRD) in February 2016 from a 3.8-million-year-old early human ancestor from the Woranso-Mille paleontological site, located in the Afar region of Ethiopia, represents a time interval between 4.1 and 3.6 million years ago when early human ancestor fossils are extremely rare, especially outside the Woranso-Mille area.
In recent Pew Survey data, 75 percent of moderate Democrats believe global climate change is a major threat to the well-being of the United States while 94 percent of Democrats who skew farther left believe that, up 30 percent from 2013.

Overall, more Americans feel that way, 57 percent this year versus 40 percent in 2013, but that increase is almost all on the left. Among the right, Republicans and people who vote Republican, that belief was 27 percent in 2019, up from 22 percent in 2013.
The salty ocean is the last place you'd expect to find fresh water but a remote-controlled vehicle deployed from the research vessel G.O. Sars found, collected and measured just that during a Norwegian Sea expedition in 2017. 

The Norwegian Sea is near the Arctic, between the North Sea and the Greenland sea, separated from the Atlantic Ocean by Iceland. 

The leakage likely originated from a large pocket of fresh water, otherwise known as an aquifer, hidden beneath the sediment of the seabed, a remnant of the last ice age.
If you insist your baby has to breastfeed for a year you have a cultural heritage to justify it. Extinct species such as Australopithecus africanus likely breastfed for that long.

How could scholars determine how long A. africanus  breastfed? Like trees, teeth contain growth rings that can be counted to estimate age. Teeth rings also incorporate dietary minerals as they grow. Breast milk contains barium, which accumulates steadily in an infant's teeth and then drops off after weaning. In a new study, researchers analyzed trace minerals in two sets of fossilized A. africanus teeth from the Sterkfontein Cave outside Johannesburg, South Africa.
One thing that makes the science community spit its Fresca out its collective nose is the organic industry's claims to be more natural than conventional.

Mutagenesis, where seeds are literally dunked in chemical and radiation baths in hopes to get a good mutation, is placed under the organic halo (along with 50 synthetic ingredients exempted because there is "no organic alternative") but if one gene is moved from a Pacific Salmon to an Atlantic salmon so the latter grows faster, it is Frankenfish to environmental lawyers.
