Making fish farming in eastern Africa's Lake Victoria sustainable

Overfishing, water shortages and pollution—these are just some of the environmental problems Lake Victoria has been facing over the last few decades. Bordered by Kenya, Tanzania and Uganda, the world's second largest freshwater lake provides the main source of income for the populations living around the Lake Victoria basin. However, the environmental pressures put on the lake have seriously compromised fish farmers' livelihoods.

Home birth may start babies off with health-promoting microbes

For all of human history, babies have been born where their mothers lived—whether in a house, hut or cave. Only in the last century has birth moved out of the home and into the hospital. How has that changed the types of microbes that live in and on our bodies—collectively known as the microbiome—which we know are vital to human health?

The internet is surprisingly fragile, crashes thousands of times a year, and no one is making it stronger

How could a small internet service provider (ISP) in Pennsylvania cause millions of websites worldwide to go offline? That's what happened on June 24, 2019 when users across the world were left unable to access a large fraction of the web. The root cause was an outage suffered by Cloudflare, one of the internet's leading content hosts on which the affected websites relied.

Bioinspired MXene-based actuators for programmable smart devices

During photosynthesis, natural leaves with elaborate architectures and functional components can harvest and convert solar energy into chemical fuels that are converted into energy. The biological energy production has provided materials scientists a new bioinspired paradigm to produce many autonomous systems, including light-triggered motion. In a recent report, Guofo Cai and co-workers at the departments of Materials Science and Engineering, Astronautic Science and Mechanics, and Chemical Engineering, developed an unprecedented bilayered actuator base on MXene (Ti3C2Tx)-cellulose composites (MXCC) and polycarbonate (PC) membranes.

How invading fungus forces zombie ant's death grip

If it's thoughts of zombies that keep you awake at night, you shouldn't be worried about zombie humans; it's the carpenter ants (Camponotus castaneus) that should concern you most. When infected by a specialised fungus (Ophiocordyceps unilateralis sensu lato), the hapless ants are unable to resist its potent power. Losing free will, the unfortunate victims locate tall pieces of vegetation, marching to a high point before the fungal infection forces them to clamp their mandibles—jaws—tightly onto a leaf vein or twig. There, the ill-fated host expires, only to be consumed from within by its evil fungal lodger, ready to scatter its spores below in the hope of infecting the next unsuspecting victim. Yet, despite the insects' loss of control, Colleen Mangold from Pennsylvania State University, USA, explains that the fungus does not attack their brains directly: 'the mandibular muscles ... of infected ants are extensively colonised by the fungus', she says. Wondering how the fungus exerts control over the ants' powerful jaw muscles, Mangold and PI David Hughes decided to take a closer look inside the muscle itself. They have discovered that the fungus invades the mandibular muscles, breaks open the membrane covering the muscle fibres and forces the muscle to contract so forcefully that it wrecks the minute muscle filaments that slide past each other. The team publishes the discovery in Journal of Experimental Biology at http://jeb.biologists.org.

Researchers deploy a novel mobile lab for rapid, real-time pathogen testing in the field

University of Minnesota researchers have refined testing methods for tick-borne diseases in the field by using a new, deployable mobile laboratory and performing genetic sequencing of key pathogens to better understand how they move, evolve and function. The U of M research team based in the College of Veterinary Medicine (CVM) is one of the first in the U.S. to use this technology for tick-borne pathogens in this specific way.

Emotion-detection applications built on outdated science, report warns

Software that purportedly reads emotions in faces is being deployed or tested for a variety of purposes, including surveillance, hiring, clinical diagnosis, and market research. But a new scientific report finds that facial movements are an inexact gauge of a person's feelings, behaviors or intentions.

Timing of spay, neuter tied to higher risk of obesity and orthopedic injuries in dogs

Spaying or neutering large-breed dogs can put them at a higher risk for obesity and, if done when the dog is young, nontraumatic orthopedic injuries, reports a new study based on data from the Morris Animal Foundation Golden Retriever Lifetime Study. The spay/neuter study was published today in the journal PLOS ONE.

Jumbo squid mystery solved

The culprit responsible for the decline of Mexico's once lucrative jumbo squid fishery has remained a mystery, until now. A new Stanford-led study published in the ICES Journal of Marine Science identifies shifting weather patterns and ocean conditions as among the reasons for the collapse, which spells trouble for the Gulf of California's marine ecosystems and fishery-dependent economies. It could also be a sign of things to come elsewhere.

Over-claiming knowledge predicts anti-establishment voting

In light of the election and ballot victories of populist, anti-establishment movements, many people have been trying to better understand the behaviors and motivations of voters. Studying voter behavior on an EU treaty, social psychologists in the Netherlands found that knowledge overclaiming predicts anti-establishment voting, particularly at the radical right.
