A 37-year survey of monarch populations in North Central Florida shows that caterpillars and butterflies have been declining since 1985 and have dropped by 80 percent since 2005.

With its wind and precipitation patterns, the South Asian Monsoon influences the lives of several billion people. Recent studies indicate that its drivers are more complex than previously assumed. Scientists from the GEOMAR Helmholtz Centre for Ocean Research Kiel have now published a reconstruction of precipitation over the eastern Indian Ocean over the past one million years in the international journal Nature Communications. It points to connections with controlling processes in the southern hemisphere that have received little attention so far.

Extreme drought is one of the effects of climate change that is already being perceived.  This year, the decrease in rainfall and the abnormally hot temperatures in northern and eastern Europe have caused large losses in cereals and potato crops and in other horticultural species. Experts have long warned that to ensure food security it is becoming necessary to use plant varieties that are productive in drought conditions. Now, a team led by the researcher at the Center for Research in Agricultural Genomics (CRAG) Ana Caño-Delgado has obtained plants with increased drought resistance by modifying the signaling of the plant steroid hormones, known as brassinosteroids. The study, published in the journal Nature Communications, is the first to find to find a strategy to increase hydric stress resistance without affecting overall plant growth.

A team of more than 100 scientists has assessed global warming's impact on thousands of tree species across the Amazon rainforest, assessing the winners and losers from 30 years of climate change.

An enzyme known to help our liver get rid of ammonia also appears to be good at protecting our retina, scientists report.

Curcumin – the active ingredient in turmeric spice – is sometimes touted as having ‘miracle’ medicinal qualities for those who consume it.

The Boba Co. and four other Simon Fraser University (SFU)-related ventures took home prizes from the university’s annual product competition.

When assessing the health of reclaimed land, look for the bugs, says a University of Alberta land reclamation researcher.

The ozone hole that forms over the Antarctic each September is primarily driven by two factors: the amount of ozone-destroying chlorine in the polar stratosphere and the availability of ice crystals in stratospheric clouds for the chlorine to bind to. This year, the super-cold stratospheric temperatures measured by NOAA and NASA meant conditions were ripe for the development of ice clouds - and a big ozone hole.

Researchers at the University of Waterloo have developed a new system that could significantly speed up the discovery of new drugs and reduce the need for costly and time-consuming laboratory tests.
