Blushing plants reveal when fungi are growing in their roots
Blushing plants reveal when fungi are growing in their roots
Scientists have created plants whose cells and tissues 'blush' with beetroot pigments when they are colonised by fungi that help them take up nutrients from the soil. We can now follow how the relationship between the fungi and plant root develops, in real-time, from the moment they come into contact.

Scientists reverse age-related memory loss in mice
Scientists reverse age-related memory loss in mice
Scientists at Cambridge and Leeds have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age. Although our study was only in mice, the same mechanism should operate in humans - the molecules and structures in the human brain are the same as those in rodents.

Brain 'noise' keeps nerve connections young
Brain ’noise' keeps nerve connections young
Researchers have found that a form of neuron-to-neuron communication that has long been dismissed as 'background noise' is required to keep nerve junctions intact as animals age. The finding suggests that defects in this type of neural communication could contribute to neurodegenerative disorders and other brain conditions.

Chromosomes separation under focus
Chromosomes separation under focus
A team from the University of Geneva has identified important regulatory mechanisms of the protein responsible for chromosome separation during cell division. During cell division, chromosomes are duplicated and separated so that one copy of each chromosome is inherited by each of the two emerging daughter cells.

Root exudation and biological nitrification potential in pearl millet can boost sustainable agriculture
Root exudation and biological nitrification potential in pearl millet can boost sustainable agriculture
Agriculture is the main source for the majority of the input of reactive N to terrestrial systems; large amounts of fertilizer N are lost from the root zone as nitrate through leaching and denitrification. Avoiding the combination of high external inputs with low resource use efficiency remains a major concern for the sustainability of N in agroecosystems.

Toxicity testing on the placenta and embryo
Toxicity testing on the placenta and embryo
Researchers at ETH Zurich have developed a cell culture test to detect substances that are directly or indirectly harmful to embryos. Based on an existing test used for developing new drugs and chemicals, the augmented version is designed to help reduce the number of animal experiments. Drugs must be safe not just for the patients; in the case of pregnant patients, drugs must also be safe for the unborn children still in the womb.

DNA regulator offers new hope for Hodgkin lymphoma treatment
DNA regulator offers new hope for Hodgkin lymphoma treatment
Researchers at The Australian National University (ANU) have discovered how a DNA-binding protein sustains Hodgkin lymphoma. The world-first discovery has the potential to help treat the rare cancer with the development of therapeutics that target cells once they become cancerous. The findings are published in EMBO Reports .

The climate impact of wild pigs greater than a million cars
The climate impact of wild pigs greater than a million cars
By uprooting carbon trapped in soil, wild pigs are releasing around 4.9 million metric tonnes of carbon dioxide annually across the globe, the equivalent of 1.1 million cars. An international team led by researchers from The University of Queensland and The University of Canterbury have used predictive population models, coupled with advanced mapping techniques to pinpoint the climate damage wild pigs are causing across five continents.

’Springing forward’ affects early birds less than night owls
Every spring, the Daylight Saving Time shift robs people of an hour of sleep-and a new study shows that DNA plays a role in how much the "spring forward” time change affects individuals. People whose genetic profile makes them more likely to be "early birds” the rest of the year can adjust to the time change in a few days, the study shows.

New 3D images of shark intestines show they function like Nikola Tesla's valve
New 3D images of shark intestines show they function like Nikola Tesla’s valve
Contrary to what popular media portrays, we actually don't know much about what sharks eat. Even less is known about how they digest their food, and the role they play in the larger ocean ecosystem. For more than a century, researchers have relied on flat sketches of sharks' digestive systems to discern how they function - and how what they eat and excrete impacts other species in the ocean.

Cancer development is influenced by tissue type
Cancer development is influenced by tissue type
Why identical mutations cause different types of cancer Why do alterations of certain genes cause cancer only in specific organs of the human body? Scientists have now demonstrated that cells originating from different organs are differentially susceptible to activating mutations in cancer drivers: The same mutation in precursor cells of the pancreas or the bile duct leads to fundamental different outcomes.

How micro-circuits in the brain regulate fear
How micro-circuits in the brain regulate fear
The brain mechanisms underlying the suppression of fear responses have attracted a lot of attention as they are relevant for therapy of human anxiety disorders. Despite our broad understanding of the different brain regions activated during the experience of fear, how fear responses can be suppressed remains largely elusive.
