Blessing in disguise: Mycoviruses enhance fungicide effectiveness against plant pathogens      (via sciencedaily.com)     Original source 

Researchers discovered that mycoviruses, or oomycete viruses, can increase the sensitivity of plant pathogenic oomycete to fungicides like metalaxyl. Their findings suggest greater potential for mycoviruses in biocontrol and contributing to sustainable agriculture.

What happens when neutron stars collide?      (via sciencedaily.com)     Original source 

New simulations show that hot neutrinos created at the interface of merging binary neutron stars are briefy trapped and remain out of equilibrium with the cold cores of the stars for 2 to 3 milliseconds.

Odors are encoded in rings in the brain of migratory locusts      (via sciencedaily.com)     Original source 

Researchers describe how odors are encoded in the antennal lobe, the olfactory center in the brain of migratory locusts. Using transgenic locusts and imaging techniques, the researchers were able to show a ring-shaped representation of odors in the brain. The pattern of olfactory coding in the antennal lobe is the same at all stages of locust development. A better understanding of olfactory coding in the locust brain should help to learn more about how the behavior of these insects is controlled, especially their swarming.

Fishy parenting? Punishing offspring encourages cooperation      (via sciencedaily.com)     Original source 

Scientists discovered that Neolamprologus savoryi fish use punishment to encourage offspring to cooperate in brood care, revealing advanced cognitive abilities previously thought unique to higher vertebrates. This study highlights that punishment for promoting cooperation exists beyond human societies, prompting a reevaluation of animal intelligence.

Where to put head and tail?      (via sciencedaily.com)     Original source 

Formation of the body axes is a critical part of embryonic development. They guarantee that all body parts end up where they belong and that no ears grow on our backs. The head-tail axis, for example, determines the orientation of the two ends of the body. It was previously assumed that this axis is largely determined by the interplay between the Nodal and BMP signals. However, there appears to be another player in this system, as researchers have now discovered by using an embryo-like model system they developed. In the absence of BMP, the signalling molecule beta-catenin takes on the role of the Nodal antagonist. This new mechanism could be a flexible solution for axis formation in embryos with different shapes.

Astronomers see a massive black hole awaken in real time      (via sciencedaily.com)     Original source 

In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory's Very Large Telescope (ESO's VLT), to track how the galaxy's brightness has varied. In a study out today, they conclude that they are witnessing changes never seen before in a galaxy -- likely the result of the sudden awakening of the massive black hole at its core.

How the ketogenic diet improves healthspan and memory in aging mice      (via sciencedaily.com)     Original source 

The ketogenic diet has its fanatics and detractors among dieters, but either way, the diet has a scientifically documented impact on memory in mice. While uncovering how the high fat, low carbohydrate diet boosts memory in older mice, scientists identified a new molecular signaling pathway that improves synapse function and helps explain the diet's benefit on brain health and aging.

Treating the gut-brain connection with B vitamins to treat Parkinson's Disease      (via sciencedaily.com)     Original source 

A study has revealed a link between gut microbiota and Parkinson's disease. The researchers discovered a decrease in bacterial genes related to the synthesis of vitamins B2 and B7. The lack of these genes was associated with reduced intestinal short-chain fatty acids and polyamines, agents that maintain the intestinal barrier and prevent the leakage of toxins into the blood that can then access the brain. Using B vitamin therapy to address these deficiencies may restore the barrier and treat Parkinson's disease.

Nile perch invasion triggered genetic bottlenecks in Lake Victoria's endemic cichlids      (via sciencedaily.com)     Original source 

Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists. Through large-scale comparative genomic analyses, the researchers found concrete proof in the collective genome of multiple species that this artificially introduced perch decimated many local fish populations, causing a 'bottleneck effect.'

Modified gravity theory: A million light years and still going      (via sciencedaily.com)     Original source 

In a breakthrough discovery that challenges the conventional understanding of cosmology, scientists have unearthed new evidence that could reshape our perception of the cosmos. New research shows that rotation curves of galaxies stay flat indefinitely far out, corroborating predictions of modified gravity theory as an alternative to dark matter.

Previously uncharacterized parasite uncovered in fish worldwide      (via sciencedaily.com)     Original source 

Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.
