Baobab trees can live for more than a thousand years and provide food, livestock fodder, medicinal compounds, and raw materials. Baobab trees are incredibly significant. However, there are growing conservation concerns and until…

Photosynthetic hacks can boost crop yield, conserve water

Maize seedling (stock image). Credit: © lamyai / stock.adobe.com Plants are factories that manufacture yield from light and carbon dioxide -- but parts of this complex process, called photosynthesis, are hindered by a lack of raw materials and machinery. To optimize production, scientists from the University of Essex have resolved two major photosynthetic bottlenecks to…

Pollinating opossums confirm decades-long theory

Opossum (stock image). Credit: © Riverwalker / Adobe Stock In Brazil there is a plant so strange that researchers predicted -- and 27 years later, proved -- that opossums are key to its pollination. The findings are published in the Ecological Society of America's journal Ecology. The plant Scybalium fungiforme, a little-known fungus-like species of…

Grain traits traced to ‘dark matter’ of rice genome

Rice plant (stock image). Credit: © apisitwilaijit29 / Adobe Stock Domesticated rice has fatter seed grains with higher starch content than its wild rice relatives -- the result of many generations of preferential seed sorting and sowing. But even though rice was the first crop to be fully sequenced, scientists have only documented a few…

Experts unlock key to photosynthesis, a find that could help us...

Green leaf in sunlight (stock image). Credit: © Korn V. / Adobe Stock Scientists have solved the structure of one of the key components of photosynthesis, a discovery that could lead to photosynthesis being 'redesigned' to achieve higher yields and meet urgent food security needs. The study, led by the University of Sheffield and published…

Antimicrobial resistance is drastically rising

Chickens (stock image). Credit: © Alexbedoya / Adobe Stock The world is experiencing unprecedented economic growth in low- and middle-income countries. An increasing number of people in India, China, Latin America and Africa have become wealthier, and this is reflected in their consumption of meat and dairy products. In Africa, meat consumption has risen by…

Controversial insecticides shown to threaten survival of wild birds

Sparrows in a field (stock image). Credit: © Ingo Bartussek / Adobe Stock New research at the University of Saskatchewan (USask) shows how the world's most widely used insecticides could be partly responsible for a dramatic decline in songbird populations. A study published in the journal Science on Sept. 13 is the first experiment to…
