Yeast and bacteria together biosynthesize plant hormones for weed control

Plants regulate their growth using hormones, including a group called strigolactones that prevent excessive budding and branching. Strigolactones also help plant roots form symbiotic relationships with microorganisms that allow the plant to absorb nutrients from the soil. These two factors have led to agricultural interest in using strigolactones to control the growth of weeds and root parasites,...

Brain microstructural damage related to cognitive dysfunction and steroid medication in lupus patients

Researchers attempted to unravel such mechanisms by adopting non-invasive diffusion magnetic resonance imaging (MRI) to study the brains of SLE patients, particularly the white matter, coupled with computerized neuropsychological assessment. White matter lies beneath the grey matter cortex in the human brain and comprises millions of bundles of nerve fibers that transmit signals to different brain...

Now we’re cooking with lasers

Imagine having your own digital personal chef; ready to cook whatever you want, tailoring the shape, texture, and flavor just for you -- all at the push of a button. Engineers have been working on doing just that, using lasers for cooking and 3D printing technology for assembling foods. In their new study they discovered that laser-cooked meat shrinks 50% less, retains double the moisture content,...

Quantitative assessment for sustainable agriculture

Scientists have assembled a quantitative assessment for agriculture sustainability for countries around the world based not only on environmental impacts, but economic and social impacts, as well. The Sustainable Agriculture Matrix, or SAM, provides independent and transparent measurements of agricultural sustainability at a national level that can help governments and organizations to evaluate...

The microbial molecule that turns plants into 'zombies'

A newly discovered manipulation mechanism used by parasitic bacteria to slow down plant aging, may offer new ways to protect disease-threatened food crops. Research has identified a manipulation molecule produced by Phytoplasma bacteria to hijack plant development. When inside a plant, this protein causes key growth regulators to be broken down, triggering abnormal growth. The new findings show...

Coral reefs are 50% less able to provide food, jobs, and climate protection than in 1950s, putting millions at risk

The capacity of coral reefs to provide ecosystem services such as food and jobs, relied on by millions of people worldwide, has declined by half since the 1950s, according to a new study. Other findings are equally bleak: the authors found that global coverage of living corals had declined by about half since the 1950s and consequently, the diversity of species had also declined, by more than 60...

Faster research through automation: New way to count micronuclei in cells

Researchers have created a novel automated program that accurately and quickly counts micronuclei in stained images. Micronuclei are small nucleus-like structures that are markers of pathologies such as cancer. The development of this automated program will be useful for future research into micronuclei and may aid in the diagnosis and tracking of a range of pathologies.

When organoids meet coronaviruses

Researchers established an organoid biobank to search for the genes that are essential for the spreading of a SARS-CoV2 infection. Their study highlights the usefulness of organoids for basic research into coronaviruses, as well as highlighting potential drug targets.

How do higher waves cause more ice clouds? Research expedition into arctic sea explains

Global warming is causing a rapid decline in sea-ice area, which affects weather patterns and, surprisingly, increases wave height in the Arctic. In a new study, Japanese scientists analyzed data from a 2018 research expedition into Chukchi Sea to demonstrate the peculiar link that exists between sea spray induced by high waves and the formation of ice-containing clouds. Their results pave the way...

Researchers improve optical tissue clearing method to diagnose cancer

The ability to visualize cancerous tumors and metastatic tissue three dimensionally (3D) can help clinicians diagnose the precise type and stage of cancer, while also informing the best treatment methods. To obtain an even clearer tissue for imaging, a research team based in Japan has tested the effectiveness of specialized hydrogels. Acting as a 3D molecular network, these hydrogels can rapidly...
