“The challenge is getting into those hidden places,” says Machado. “It’s rare that Aedes aegypti breeding areas are found out in the open, like on a sidewalk, because when people see them, they destroy them. But with drones, we can get into areas we just can’t otherwise.”

Birdview has carried out studies with several partners since 2021, including the United Nations, the University of São Paulo (USP), and the state-owned Brazilian Agricultural Research Corporation (Embrapa), to better understand the effectiveness of releasing the disease-fighting mosquitoes with drones. First they looked at how the mechanism of the drone and outside conditions, like wind turbulence, affected the survival rate of the mosquitoes and their ability to fly.

The results were positive, so they moved on to flight-and-release tests in the Brazilian states of Pernambuco and Paraná, as well as Florida, where they’ve been working with the Lee County Mosquito Control District to see how far the mosquitoes spread upon release. They used the “mark, release and recapture” method, which involves sterile male mosquitoes being marked with a certain color before being released and later recaptured with traps so the team could see how far they had flown. They also set traps where eggs could be laid and monitored.

In the last decade, thanks to advances in AI, the internet of things, machine learning and sensor technologies, the fantasy of digital twins has taken off. BMW has created a digital twin of a production plant in Bavaria. Boeing is using digital twins to design airplanes. The World Economic Forum hailed digital twins as a key technology in the “fourth industrial revolution.” Tech giants like IBM, Nvidia, Amazon and Microsoft are just a few of the big players now providing digital twin capabilities to automotive, energy and infrastructure firms.

The inefficiencies of the physical world, so the sales pitch goes, can be ironed out in a virtual one and then reflected back onto reality. Test virtual planes in virtual wind tunnels, virtual tires on virtual roads. “Risk is removed” reads a recent Microsoft advertorial in Wired, and “problems can be solved before they happen.”

All of a sudden, Dirk Helbing and Javier Argota Sánchez-Vaquerizo wrote in a 2022 paper, “it has become an attractive idea to create digital twins of everything.” Cars, trains, ships, buildings, airports, farms, power plants, oil fields and entire supply chains are all being cloned into high-fidelity mirror images made of bits and bytes. Attempts are being undertaken to twin beaches, forests, apple orchards, tomato plants, weapons and war zones. As beaches erode, forests grow and bombs explode, so too will their twins, watched closely by technicians for signals to improve outcomes in the real world.

PORTLAND, Maine (AP) — Avian influenza is killing tens of thousands of seals and sea lions in different corners of the world, disrupting ecosystems and flummoxing scientists who don’t see a clear way to slow the devastating virus.

The worldwide bird flu outbreak that began in 2020 has led to the deaths of millions of domesticated birds and spread to wildlife all over the globe. This virus isn’t thought to be a major threat to humans, but its spread in farming operations and wild ecosystems has caused widespread economic turmoil and environmental disruptions.

Seals and sea lions, in places as far apart as Maine and Chile, appear to be especially vulnerable to the disease, scientists said. The virus has been detected in seals on the east and west coasts of the U.S., leading to deaths of more than 300 seals in New England and a handful more in Puget Sound in Washington. The situation is even more dire in South America, where more than 20,000 sea lions have died in Chile and Peru and thousands of elephant seals have died in Argentina.

Essential tremor is a movement disorder that causes involuntary, rhythmic shaking (tremor), especially in the hands. It is distinguished from tremor that results from other disorders or known causes, such as Parkinson’s disease or head trauma. Essential tremor usually occurs alone, without other neurological signs or symptoms. However, some experts think that essential tremor can include additional features, such as mild balance problems.

Essential tremor usually occurs with movements and can occur during many different types of activities, such as eating, drinking, or writing. Essential tremor can also occur when the muscles are opposing gravity, such as when the hands are extended. It is usually not evident at rest.

In addition to the hands and arms, muscles of the trunk, face, head, and neck may also exhibit tremor in this disorder; the legs and feet are less often involved. Head tremor may appear as a “yes-yes” or “no-no” movement while the affected individual is seated or standing. In some people with essential tremor, the tremor may affect the voice (vocal tremor).

Until now, it was not clear how hepatocytes were assigned tasks related to their localization. Researchers at the Spanish National Cancer Research Center (CNIO) have discovered that a gene, mTOR, is responsible for organizing the hepatocyte position map.

They also found that what triggers hepatocyte specialization is feeding after birth. The difference is marked by how nutrients reach the organism before and after birth: with no interruptions through the umbilical cord in one case, or in an intermittent fashion –when eating– in the other. The alternation of periods with and without available nutrients activates the mTOR gene and causes the hepatocytes to specialize, which completes the maturation of the liver.

The company’s long-lasting products may even help cut down on discarded food, around a third of which is tossed globally every year.

That waste then releases methane, a powerful heat-trapping gas, as it goes through the process of breaking down in landfills, contributing to rising global temperatures linked to extreme weather events that frequently cause displacement or damage vital food crops.

According to Packaging Digest, even though foodberries are perishable, they are safe and tasty to eat for anywhere from 60 to 90 days, though frozen items can last for more than a year.

Researchers from Weill Cornell Medicine have discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells that help in preventing allergic reactions to food and the bacteria themselves during early development.

The study published in the journal Science Immunology on March 15, 2024, revealed that bacteria abundant in the guts of newborns produce serotonin, which promotes the development of immune cells called T-regulatory cells or Tregs. These cells suppress inappropriate immune responses to help prevent autoimmune diseases and dangerous allergic reactions to harmless food items or beneficial gut microbes.

Scientists are embarking on a £1.1 million project aimed at revolutionising drug production by using food by-products to develop new antimicrobial drugs.

Led by the University of Strathclyde in collaboration with the University of Surrey and GSK, the research endeavours to make antimicrobial production more cost-effective and sustainable, thereby addressing the pressing global challenge of antimicrobial resistance.

The project seeks to leverage bacteria, particularly Streptomyces, known for their potential to produce various drugs including antimicrobials. By harnessing food by-products, the team is aiming to device a less carbon-intensive process for biomanufacturing, which could pave the way for a range of medications including anti-parasitic, anti-cancer, anti-fungal, and immunosuppressant drugs.
