A new antibiotic acts in two ways to control bacteria.

New class of antibiotics found to fight antimicrobial resistance

Science Notes: WHO has declared AMR as one of the top 10 global public health threats

Wistar Institute scientists have discovered a new class of compounds that uniquely combine direct antibiotic killing of pan drug-resistant bacterial pathogens with a simultaneous rapid immune response for combatting antimicrobial resistance (AMR). These findings were published in December in Nature. The World Health Organization (WHO) has declared AMR as one of the top 10 global […] Read more


France to help farmers to abandon glyphosate weedkiller

Paris | Reuters – France will give financial aid to farmers who agree to halt use of glyphosate, the farm ministry said on Monday after President Macron said he had failed with efforts to ban use of the weedkiller by 2021.

Glyphosate not a carcinogen, U.S. EPA reiterates

Chicago | Reuters — The U.S. Environmental Protection Agency (EPA) said on Tuesday that glyphosate, a chemical in many popular weed killers, is not a carcinogen, contradicting decisions by U.S. juries that found it caused cancer in people. The EPA’s announcement reaffirms its earlier findings about the safety of glyphosate, the key ingredient in Bayer’s […] Read more


Over 30 years, the active ingredient volume of herbicide applied on crops has declined in Ontario, mostly because glyphosate 
is applied at lower rates than the herbicides it replaces.

Glyphosate drives long-term herbicide changes

Ontario keeps track of detailed herbicide use every five years, which shows how the use of active ingredient has declined

A study of glyphosate use in Ontario shows the herbicide has created significant change in crop management. It shows that while corn and soybean acreage and yield have increased in the province since 1983, the impact of herbicide use per acre has declined, in large part because glyphosate has displaced other herbicide chemistries. Why it […] Read more

Stop using antibiotics in healthy animals, WHO urges farmers

London | Reuters – The World Health Organization urged farmers on Tuesday to stop using antibiotics to promote growth and prevent disease in healthy animals because the practice fuels dangerous drug-resistant superbug infections in people. Describing a lack of effective antibiotics for humans as “a security threat” on a par with “a sudden and deadly […] Read more
