Beer byproduct mixed with manure proves an excellent pesticide
A new study published by the open access publisher Frontiers has demonstrated that beer bagasse and rapeseed cake can be used as effective biodisinfestation treatments to reduce populations of soil parasites and increase crop yields. Researchers demonstrated that using these organic treatments in soils significantly reduced root-knot nematodes and boosted beneficial soil populations, as well as reducing waste from the agricultural industry by incorporating organic by-products as a treatment instead of harmful chemical fumigants.

A fiery past sheds new light on the future of global climate change
Centuries-old smoke particles preserved in the ice reveal a fiery past in the Southern Hemisphere and shed new light on the future impacts of global climate change, according to a research led by Harvard University and a group of international researchers from the Desert Research Institute in Nevada and the University of Hong Kong, etc. recently published in Science Advances.

Right off the bat: Navigation in extra-large spaces
How we and other mammals manage to navigate large-scale environments even though the brain's spatial perception circuits are seemingly suited to representing much smaller areas? A team of researchers from the Weizmann Institute of Science, led by Professor Nachum Ulanovsky of the Neurobiology Department, tackled this riddle by thinking outside the experimental box. By combining an unusual research model -- fruit bats -- with an unusual setting -- a 200-meter-long bat-tunnel -- they were successful in revealing a novel neuronal code for spatial perception.

Browning could make lakes less productive, affecting food webs and fish
As more dissolved organic matter enters lakes across the northeast United States, darkening the lakes in a phenomena called 'browning,' new research shows that these waters may be growing less productive and able to sustain less life.

Less is more? New take on machine learning helps us "scale up" phase transitions
Researchers from Tokyo Metropolitan University have enhanced "super-resolution" machine learning techniques to study phase transitions. They identified key features of how large arrays of interacting "particles" behave at different temperatures by simulating tiny arrays before using a convolutional neural network to generate a good estimate of what a larger array would look like using "correlation" configurations. The massive saving in computational cost may realize unique ways of understanding how materials behave.

Being born very preterm or very low birthweight is associated with continued lower IQ performance into adulthood
The average IQ of adults who were born very preterm (VP) or at a very low birth weight (VLBW) has been compared to adults born full term by researchers from the Department of Psychology at the University of Warwick. Researchers have found VP/VLBW children may require special support in their education to boost their learning throughout childhood.

New GSA Bulletin articles published ahead of print in May
The Geological Society of America regularly publishes articles online ahead of print. For April, GSA Bulletin topics include multiple articles about the dynamics of China and Tibet; new insights into the Chicxulub impact structure; and the dynamic topography of the Cordilleran foreland basin. You can find these articles at https://bulletin.geoscienceworld.org/content/early/recent.

New tool activates deep brain neurons by combining ultrasound, genetics
A team at Washington University in St. Louis has developed a new brain stimulation technique using focused ultrasound that is able to turn specific types of neurons in the brain on and off and precisely control motor activity without surgical device implantation.

Exoskeleton-assisted walking may improve bowel function in people with spinal cord injury
"Our results support the idea that walking may have a beneficial effect on bowel function," said Dr. Gorman at the University of Maryland. Subjects in the exoskeletal-assisted walking program saw some improvement in bowel function compared to a control group. "We saw a notable reduction in bowel evacuation time, with 24 percent of participants reporting an improved experience," said Dr. Forrest at Kessler Foundation. "Also, participants' stools trended toward better consistency, supporting our hypothesis that this intervention may improve several measures of bowel function."

Same difference: Two halves of the hippocampus have different gene activity
A study of gene activity in the brain's hippocampus, led by UT Southwestern researchers, has identified marked differences between the region's anterior and posterior portions. The findings, published today in Neuron, could shed light on a variety of brain disorders that involve the hippocampus and may eventually help lead to new, targeted treatments.

Researchers create new CRISPR tools to help contain mosquito disease transmission
UC San Diego scientists have developed a genetics toolkit that helps pave the way to a gene drive designed to stop Culex mosquitoes from spreading disease. Much less studied than other genera, Culex mosquitoes spread devastating afflictions stemming from West Nile virus, Japanese encephalitis virus and the pathogen causing avian malaria.

Declining biodiversity in wild Amazon fisheries threatens human diet
A new study of dozens of wild fish species commonly consumed in the Peruvian Amazon says that people there could suffer major nutritional shortages if ongoing losses in fish biodiversity continue. Furthermore, the increasing use of aquaculture and other substitutes may not compensate.

Elucidating how the production of antibodies is regulated, one cell at a time
A study coordinated by Luís Graça, principal investigator at the Instituto de Medicina Molecular (iMM; Portugal) used lymph nodes, tonsils and blood, to show how the cells that control production of antibodies are formed and act. The results published now in the scientific journal Science Immunology unveiled key aspects about the regulation of antibody production, with significant importance for diseases where antibody production is dysregulated such as autoimmune diseases or allergies.
