Geologists Simulate Soil Conditions to Help Grow Plants on Mars

Humankind's next giant step may be onto Mars. But before those missions can begin, scientists need to make scores of breakthrough advances, including learning how to grow crops on the red ...

US Corn Crop's Growing Sensitivity to Drought Revealed

New management approaches and technology have allowed the US. Corn Belt to increase yields despite some changes in climate. However, soil sensitivity to drought has increased significantly, according ...

Genome Sequencing Shows Climate Barrier to Spread of Africanized Bees

Since the 1950s, 'Africanized' honeybees have spread north and south across the Americas until apparently coming to a halt in California and northern Argentina. Now genome sequencing of hundreds of ...

Plants Communicate at a Molecular Level

Biologists have discovered how tomato plants identify Cuscuta as a parasite. The plant has a protein in its cell walls that is identified as 'foreign' by a receptor in the ...

More Diversity Needed in Oil Palm Plantations

Growing global demand for palm oil has led to a rapid spread of oil palm monoculture plantations in South East Asia, often associated with the loss of habitats and biodiversity. Plantations are ...

Atmospheric Dust Levels Are Rising in the Great Plains

A study finds that atmospheric dust levels are rising across the Great Plains at a rate of up to 5% per year. The trend of rising dust parallels expansion of cropland and even seasonal crop cycles. ...

Planting Parasites: Unveiling Common Molecular Mechanisms of Parasitism and Grafting

Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing one ...

Crabs Are Key to Ecology and Economy in Oman

The intertidal mudflats of Barr Al Hikman, a nature reserve at the south-east coast of the Sultanate Oman, are crucial nursery grounds for numerous crab species. In return, crabs are a vital element ...

Dietary Migration of Impala Rivals the Geographical Migration of Serengeti Wildebeest

A new study shows the Impala's migration is a 'dietary migration', where they switch from eating mostly grass in the wet season, to eating more tree leaves or 'browse' during ...

The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout from branches and eventually reach the soil. The tree also has a unique relationship with a wasp that has coevolved ...

Pollinator Monitoring More Than Pays for Itself

Study found pollinator monitoring schemes, which often combine expert and volunteer observations, provide high-quality scientific data at a far lower cost than individual research ...

Rising nitrous oxide emissions are jeopardizing the climate goals of the Paris Agreement, according to a major new study. The growing use of nitrogen fertilizers in the production of food worldwide ...

Pesticides and Food Scarcity Dramatically Reduce Wild Bee Population

The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers found that the combined threats reduced blue orchard bee ...

Shattering Expectations: Novel Seed Dispersal Gene Found in Green Millet

Researchers generated genome sequences for nearly 600 green millet plants and released a very high-quality reference S. viridis genome sequence and also identified a gene related to seed dispersal in ...

Efficient Pollen Identification

From pollen forecasting, honey analysis and climate-related changes in plant-pollinator interactions, analysing pollen plays an important role in many areas of research. Microscopy is still the gold ...

Dozens of Mammals Could Be Susceptible to SARS-CoV-2

Numerous animals may be vulnerable to SARS-CoV-2, the virus that causes Covid-19, according to a large study modelling how the virus might infect different animals' ...

Harvesting Vegetation on Riparian Buffers Barely Reduces Water-Quality Benefits

Allowing farmers to harvest vegetation from their riparian buffers will not significantly impede the ability of those streamside tracts to protect water quality by capturing nutrients and sediment -- ...

Potential New Tool for Frost Screening in Crops

Agricultural scientists and engineers have identified a potential new tool for screening cereal crops for frost ...

New Research Sheds Light on the Reluctance of Farmers to Adopt New Technologies

Research sheds new light on a long-standing obstacle to improving agricultural productivity in developing countries: the reluctance of small-scale farmers to adopt modern technologies because of the ...

Bright Light Bars Big-Eyed Birds from Human-Altered Landscapes

New research shows the glaring light in human-altered landscapes, such as livestock pastures and crop fields, can act as a barrier to big-eyed birds, potentially contributing to their ...

Satellite Imaging to Map Groundwater Use in California's Central Valley

Researchers report in a new study a way to improve groundwater monitoring by using a remote sensing technology (known as InSAR), in conjunction with climate and land cover data, to bridge gaps in the ...

Hand Pollination, Not Agrochemicals, Increases Cocoa Yield and Farmer Income

Agroecologists compare pesticides, fertilizers, manual pollination and farming costs in ...

Can Organic Plant Protection Products Damage Crops?

Some organic pesticides contain live spores of the fungus Trichoderma to suppress other pathogens. Researchers found one Trichoderma species can cause severe rot in cobs of maize ...

Rapeseed Instead of Soy Burgers: Researchers Identify a New Source of Protein for Humans

Rapeseed has the potential to replace soy as the best plant-based source of protein for humans. In a current study, nutrition scientists found that rapeseed protein consumption has comparable ...
