Experts attributed the decline to top oil producer Saudi Arabia’s pledge on Tuesday to help stabilize the market — which in turn assuaged fears of disruptions, according to Reuters.  

Saudi and Russian officials met in Moscow on Wednesday, at which time Russian President Vladimir Putin said that the Organization of the Petroleum Exporting Countries (OPEC) and its allies would coordinate efforts “for the predictability of the oil market,” Reuters reported. 

While not part of OPEC, Russia is part of the OPEC+ group, which includes 10 oil-producing countries beyond the 13 OPEC members.  

Saudi Arabia had also said on Tuesday that it was working with its regional and international partners to prevent a rise in oil prices, Reuters reported.  

With what appeared to be Putin’s reassurances, however, also came a warning. 

At the meeting in Moscow on Wednesday, Putin also said that existing cuts to oil supplies would “most likely” continue despite ongoing concerns, according to The Guardian. 

Such a move would provide what The Guardian described as an economic windfall for Russia, which has experienced a decline in gas sales to Europe following its invasion of Ukraine last year.  

Asked if current oil supply cuts would be extended at Wednesday’s Russian Energy Week conference, Putin said that his country’s decisions “are made by consensus,” The Telegraph reported. 

“Today it looks like we will continue our cooperation,” he said.  

By Wednesday afternoon, Brent Crude Oil — a European benchmark used for global market purchases — was sitting at $86.33, or a 1.51 percent drop since the previous day, according to MarketWatch.   

Brent’s lowest point in the day occurred in the late morning eastern time, when the benchmark plunged 2.67 percent from the previous day to about $85.31. 

The West Texas Intermediate (WTI) — a futures contract traded on the New York Mercantile Exchange — was at about $84, or a 1.96 percent drop from the day before.  

Both Brent and WTI had skyrocketed by more than $3.50 on Monday, amid concerns that the war between Israel and Hamas could have knock-on effects on global oil supplies, Reuters reported.

Two of the most popular herbicides may be associated with negative neurobehavioral effects in adolescents, a new study has found.  

A pervasive problem: Scientists made these determinations for both glyphosate and 2,4-dichlorophenoxyacetic acid (2,4-D) — herbicides used for a variety of agricultural and ornamental purposes.  

• They published their findings on Wednesday in Environmental Health Perspectives.
• Following the introduction of glyphosate-resistant crops in 1996 and 2,4-D-resistant crops in 2014, these two herbicides became among the most common around the world.  

Neurotoxins and mental health: “Many chronic diseases and mental health disorders in adolescents and young adults have increased over the last two decades worldwide,” senior author Jose Ricardo Suarez, of the University of California San Diego’s Herbert Wertheim School of Public Health, said in a statement.  

“Exposure to neurotoxic contaminants in the environment could explain a part of this increase,” Suarez added.  

Connecting exposure to behavior: To investigate this hypothesis, Suarez and his colleagues measured the metabolite concentrations — intermediate products of reactions catalyzed by certain enzymes — of glyphosate, 2,4-D and DEET in human urine samples. 

• The samples came from 519 adolescents, aged 11 to 17, living in the agricultural county of Pedro Moncayo, Ecuador, in 2016.
• The researchers assessed neurobehavioral performance in five areas: attention and inhibitory control, memory and learning, language, visuospatial processing and social perception. 

Different compounds, different effects: The scientists found glyphosate, which is used in crops like corn and soy and for vegetation control in residential settings, in the urine of 98 percent of participants. 

• Glyphosate levels in urine were linked to lower scores in social perception only.
• 2,4-D — used on lawns, aquatic sites and agricultural crops — was present in 66 percent of participants.
• Higher amounts of 2,4-D were associated with lower neurobehavioral performance in attention and inhibitory control, memory, learning and language.
• DEET metabolites were not connected to neurobehavioral performance.  

Widespread reach, impacts unknown: “There is considerable use of herbicides and insecticides in agricultural industries in both developed and developing nations around the world,” first author Briana Chronister, a UC San Diego doctoral candidate, said in a statement.  

This spread is “raising exposure potential for children and adults, especially if they live in agricultural areas, but we don’t know how it impacts each stage of life,” Chronister added.  

Tracking lifelong exposures: The study occurred under the umbrella of ESPINA: The Study of Secondary Exposures to Pesticides Among Children and Adolescents, funded by the National Institute of Environmental Health Sciences.  

ESPINA, the scientists noted, seeks to investigate the impacts of pesticide exposures on the development of humans from childhood through adulthood. 

Mysteries on the market: “Hundreds of new chemicals are released into the market each year, and more than 80,000 chemicals are registered for use today,” Suarez said.  

“Sadly, very little is known about the safety and long-term effects on humans for most of these chemicals,” he added.
