Honey Bees Attracted to Glyphosate and a Common Fungicide

By Dan Nosowitz

All species evolve over time to have distinct preferences for survival. But with rapidly changing synthetic chemicals, sometimes animals don't have a chance to develop a beneficial aversion to something harmful.


New research from the University of Illinois indicates that honey beeswhich are dying en masse—may actually prefer the taste of flowers laced with pesticides that are likely harmful. The study tested honey bee consumption of different sugar syrups, some plain and some with different concentrations of common pesticides. They found that while the bees didn't care for syrup with extremely high concentrations of pesticides, at low levels, the bees flocked to those pesticides.

Among the pesticides tested were the ever-controversial glyphosate, the most common pesticide in the U.S., which previous studies have also shown to be attractive to honey bees. Chlorothalonil, which is ranked as the 10th most commonly used fungicide in the U.S., usually on peanuts and potatoes, also proved to attract more honey bees. (The connection between fungicides and honey bee health is not that clear; studies suggest they are not in themselves highly toxic, but in combination with other factors can be dangerous).

The bees did not universally prefer adulterated syrups; the researchers note that they avoided prochloraz, a fungicide sold under the name Sportak. And of course, laced sugar syrup is not the same as a flower in the wild. Still, it's another alarming bit of news about our bees.

Judge Halts Seismic Testing Permits During Shutdown

Finally, some good news about the otherwise terrible partial government shutdown. A federal judge ruled that the Trump administration cannot issue permits to conduct seismic testing during the government impasse.

The Justice Department sought to delay—or stay—a motion filed by a range of coastal cities, businesses and conservation organizations that are suing the Trump administration over offshore oil drilling, Reuters reported. The department argued that it did not have the resources it needed to work on the case due to the shutdown.

DiCaprio-Funded Study: Staying Below 1.5ºC is Totally Possible

Climate change has been called the biggest challenge of our time. Last year, scientists with the United Nations said we basically have 12 years to limit global warming to 1.5ºC to avoid planetary catastrophe.

Amid a backdrop of rising global carbon emissions, there's a real case for pessimism. However, many scientists are hopeful of a way out.

MLK Would Have Been an Environmental Leader, Too

"Injustice anywhere is a threat to justice everywhere." Dr. Martin Luther King Jr.'s words and actions continue to resonate on the 90th anniversary of his birth.

As the country honors the life and legacy of the iconic civil rights leader today, we are reminded that the social justice and the climate movements are deeply connected.

Climate Change Leading to Fatal Bird Conflicts

By Marlene Cimons

Most Europeans know the great tit as an adorable, likeable yellow-and-black songbird that shows up to their feeders in the winter. But there may be one thing they don't know. That cute, fluffy bird can be a relentless killer.

The great tit's aggression can emerge in gruesome ways when it feels threatened by the pied flycatcher, a bird that spends most of the year in Africa, but migrates to Europe in the spring to breed. When flycatchers arrive at their European breeding grounds, they head for great tit territory, knowing that great tits—being year-round European residents—know the best nesting sites.

Saving the World’s Largest Tropical Wetland

Most people have heard of the Amazon, South America's famed rainforest and hub of biological diversity. Less well known, though no less critical, is the Pantanal, the world's largest tropical wetland.

Like the Amazon, the Pantanal is ecologically important and imperiled. Located primarily in Brazil, it also stretches into neighboring Bolivia and Paraguay. Covering an area larger than England at more than 70,000 square miles, the massive wetland provides irreplaceable ecosystem services that include the regulation of floodwaters, nutrient renewal, river flow for navigability, groundwater recharge and carbon sequestration. The wetland also supports the economies of the four South American states it covers.

Trump Once Again Confuses Weather and Climate in Response to Deadly Winter Storm

President Donald Trump has once again contradicted the findings of the U.S. government when it comes to the threat posed by climate change. Days after a Department of Defense report outlined how climate-related events like wildfires and flooding put U.S. military installations at risk, Trump took to Twitter to mock the idea that the world could be getting warmer, Time reported.

Trump's tweet came in response to a massive winter storm that blanketed the Midwest and Northeast this weekend.

85 Dead in Mexican Pipeline Explosion

A dramatic pipeline explosion in central Mexico Friday has killed at least 85 people, Mexican Health Minister Jorge Alcocer Valera said Sunday night, The Associated Press reported.

The explosion occurred in a field in the municipality of Tlahuelilpan as people rushed to gather fuel from the pipeline, which had been ruptured by suspected thieves. Many were covered in oil before a fireball shot into the air.
