Laboratory could improve crop resilience In a discovery three decades in the making, scientists have acquired detailed knowledge about the internal structures and mode of regulation for a specialized protein and are proceeding to develop tools that can capitalize on its ability to help plants combat a wide range of diseases. The work, which exploits a natural process where plant cells die on purpose to help the host plant stay healthy, is expected to have wide applications in the agricultural sector, offering new ways to protect major food crops from a variety of devastating diseases, the scientists said.View the full article

Forest-based agroforestry can restore forests, promote livelihoods, and combat climate change, but emerging agroforestry initiatives focusing only on tree planting is leading to missed opportunities to support beneficial outcomes of forest management, scientists found.View the full article

New HIV research shows that small changes in the virus affect how quickly or slowly it replicates and how easily it can reawaken in the body. These insights bring researchers closer to finding ways to flush out the dormant virus and eliminate it for good.View the full article

A virus responsible for damaging cotton crops across the southern United States has been lurking in U.S. fields for nearly 20 years -- undetected. According to new research, cotton leafroll dwarf virus (CLRDV), long believed to be a recent arrival, was infecting plants in cotton-growing states as early as 2006.View the full article

Scientists analyzed almost 200 cannabis genomes to create the most comprehensive, high-quality, detailed genetic atlas of the plant to date. The atlas reveals unprecedented diversity and complexity within the species, sets the stage for advances in cannabis-based agriculture, medicine, and industry, and builds on a 10,000-year long relationship between humans and cannabis, showing that cannabis can be as important as other crops like corn or wheat.View the full article

Reducing travel speeds and using an intelligent queuing system at busy ports can reduce greenhouse gas (GHG) emissions from oceangoing container vessels by 16-24%, according to researchers. Not only would those relatively simple interventions reduce emissions from a major, direct source of greenhouse gases, the technology to implement these measures already exists.View the full article

Close to five million smuggled seahorses worth an estimated CAD$29 million were seized by authorities over a 10-year span, according to a new study that warns the scale of the trade is far larger than current data suggest. The study analyzed online seizure records from 2010 to 2021 and found smuggling incidents in 62 countries, with dried seahorses, widely used in traditional medicine, most commonly intercepted at airports in passenger baggage or shipped in sea cargo.View the full article

An analysis of data from a national health survey conducted before the pandemic found that pizza, soup and chicken are some of the main sources of sodium (salt) intake for people in all racial and ethnic groups. The study also showed clear differences among adults based on race and ethnicity.View the full article

A new species of velvet worm, Peripatopsis barnardi, represents the first ever species from the arid Karoo, which indicates that the area was likely historically more forested than at present. In the Cape Fold Mountains, we now know that every mountain peak has an endemic species. This suggests that in unsampled areas there are likely to be additional novel diversity, waiting to be found.View the full article

Parasitic worms that infect humans are not interbreeding with those that infect cattle as previously thought. This is good news for when it comes to controlling schistosomiasis, a disease caused by these worms that affects more than 200 million people globally.View the full article

A team identified herpes virus saimiri, which infects the T cells of squirrel monkeys, as a source of proteins that activate pathways in T cells that are needed to promote T cell survival.View the full article

Scientists show that wolves that are eating sea otters in Alaska have much higher concentrations of mercury than those eating other prey such as deer and moose.View the full article

Many bat species native to Germany, such as the Leisler's bat, are forest specialists. However, as it is becoming increasingly hard for them to find tree hollows in forest plantations, so they are moving to settlements instead. Using high-resolution GPS data from bats, a team led by scientists has analyzed in greater detail than ever before how Leisler's bats use their habitats, which tree species they look for when searching a roost, and which forest types they avoid. They found that these bats increasingly seek refuge in old trees in urban areas and in old buildings such as churches.View the full article

A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place.View the full article

Researchers conducted a systematic review of 99 scientific publications that compared the flora or fauna of old-growth forests, managed forests and clearcut sites in boreal Europe. The reviewed studies showed large differences in the species communities inhabiting these forest types. The species richness of full-canopy forests increases as the forest gets older. Clearcut sites are also species-rich, but they are inhabited by a distinct set of species in comparison to full-canopy forests.View the full article

Scientists, who have spent more than a decade examining the impact of artificial light at night on the world's coasts and oceans, have shown that more than one-fifth of the global ocean -- an area spanning more than 75 million sq km -- has been the subject of ocean darkening over the past two decades. Ocean darkening occurs when changes in the optical properties of the ocean reduce the depth of its photic zones, home to 90% of all marine life and places where sunlight and moonlight drive ecological interactions.View the full article

New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent.View the full article

Planting flower strips in a field with at least two species can increase the number of natural enemies of pests by 70 percent. The more flower species, the better the effect, according to a new meta-analysis.View the full article

Forests play a crucial role in promoting health and wellbeing, but not all forests provide the same benefits. A large-scale study demonstrates how specific forest characteristics -- such as canopy density and tree species diversity -- can affect various health outcomes.View the full article

A novel analysis suggests more than 3,500 animal species are threatened by climate change and also sheds light on huge gaps in fully understanding the risk to the animal kingdom.View the full article

A team of researchers has discovered 71 new native bee species belonging to the resin pot bees, or Megachile (Austrochile), which are unique to Australia and present in every state and territory except Tasmania.View the full article

New research has revealed that high densities of European honey bees could be harming Australian native bees' 'fitness' by reducing their reproductive success and altering key traits linked to survival.View the full article

When trees and soil fungi form close associations with each other, both partners benefit. Many tree species have further enhanced this cooperation by forming a concurrent symbiosis with two different groups of mycorrhizal fungi. Those trees cope better with water and nutrient scarcity, which is an important trait for forestry in the face of climate warming.View the full article
