Flesh-eating parasite case detected in US traveler returning from Central America
Fox News senior medical analyst Dr. Marc Siegel shares his perspective on whether the mosquito-borne virus in China will spread to the United States and how AI can be detrimental to children's and young adults' mental health on'Fox Report.' The first case of a travel-associated human screwworm infection has been detected in Maryland. Andrew Nixon, spokesperson for the Department of Health and Human Services, confirmed to Fox News Digital that the patient had recently returned from a trip to El Salvador, a country affected by a screwworm outbreak. The Centers for Disease Control and Prevention (CDC) worked in conjunction with the Maryland Department of Health to investigate the case. The CDC confirmed the diagnosis on Aug. 4 after experts reviewed larvae images. "The risk to public health in the United States from this introduction is very low," Nixon said.

Early Detection of Coffee Leaf Rust Through Convolutional Neural Networks Trained on Low-Resolution Images
Cabrera, Angelly, Avramidis, Kleanthis, Narayanan, Shrikanth
Coffee leaf rust, a foliar disease caused by the fungus Hemileia vastatrix, poses a major threat to coffee production, especially in Central America. Climate change further aggravates this issue, as it shortens the latency period between initial infection and the emergence of visible symptoms in diseases like leaf rust. Shortened latency periods can lead to more severe plant epidemics and faster spread of diseases. There is, hence, an urgent need for effective disease management strategies. To address these challenges, we explore the potential of deep learning models for enhancing early disease detection. However, deep learning models require extensive processing power and large amounts of data for model training, resources that are typically scarce. To overcome these barriers, we propose a preprocessing technique that involves convolving training images with a high-pass filter to enhance lesion-leaf contrast, significantly improving model efficacy in resource-limited environments. This method and our model demonstrated a strong performance, achieving over 90% across all evaluation metrics--including precision, recall, F1-score, and the Dice coefficient. Our experiments show that this approach outperforms other methods, including two different image preprocessing techniques and using unaltered, full-color images.

The Download: How AI capitalizes on catastrophe, and the Bitcoin cities of Central America
It was meant to be a temporary side job--a way to earn some extra money. Oskarina Fuentes Anaya signed up for Appen, an AI data-labeling platform, when she was still in college studying to land a well-paid position in the oil industry. But then the economy tanked in Venezuela. Inflation skyrocketed, and a stable job, once guaranteed, was no longer an option. Her side gig was now full time; the temporary now the foreseeable future.

A Panorama of Computing in Central America and the Caribbean
Despite being a poor and unequal country, Costa Rica has managed to close the gap in access to technology for its citizens, and it is now leading the way in the region. The country started the process of admission for the Organization for Economic Cooperation and Development (OECD) several years ago with reforms on laws, the creation of policies and the use of Computer Technologies to improve education, information access, financial markets, competitiveness, and a more open government. In May 2020, Costa Rica became the first Central American or Caribbean country invited to become an OECD member. The OECD has almost 60 years of existence, and its members are many of the world's more developed countries that work together to shape policies that foster prosperity, equality, opportunity, and well-being for their citizens. Costa Rica will become the 38th member, the fourth of Latin America.

ARTIFICIAL INTELLIGENCE: Researchers to use 'big data' to predict sea crimes
Researchers using artificial intelligence and "big data" plan to develop new algorithms that they say will enable them to identify, locate – and eventually predict – crimes committed in the world's oceans, from illegal fishing off the Patagonia shelf to drug smuggling in Central America to slave labor and human trafficking in the Indian Ocean. The perpetrators of these illegal, unreported and unregulated (IUU) activities collectively use vessels called "the dark fleet," not just because of their criminal activity, but because they try to hide their location by turning off their GPS tracking systems and navigating between legally operating and visible boats. "IUUs include all kinds of terrible things," said James Watson, a marine scientist expert at Oregon State University, and a principal investigator on the project. "We came into this thinking primarily about illegal fishing, but that turns out to be just the tip of the iceberg. It is much, much bigger."

Thousands of Mayan pyramids and palaces found in Guatemala
More than 60,000 previously unknown Mayan structures - including pyramids, palaces and causeways - have been revealed under jungle foliage in Guatemala in what has been hailed as a'major breakthrough'. Researchers used laser technology to look beneath the forest canopy in northern Peten - an area close to already-known Mayan cities. The lasers revealed the'breathtaking' remains of a sprawling pre-Columbian'megalopolis' that was far more complex than most specialists had ever believed. The discovery suggests that Central America supported a civilization that was, at its peak 1,500 years ago, more advanced than ancient Greek and Chinese cultures. The landscape may have been home to up to 15 million individuals and the abundance of defensive walls, ramparts and fortresses suggests that warfare was rife throughout their existence and not just at the end.

An Ancient City Emerges in a Remote Rain Forest
Most of the important archaeological sites in Central America were "discovered" by archaeologists who, in fact, didn't discover them at all but were led to the ruins by local people. I've known several Maya archaeologists who routinely started fieldwork in a new area by heading into a dive bar and hoisting beers with the locals while listening to various bullshitters spin tales about ruins they'd seen in the jungle; once in a while, a story would turn out to be true. But, because these sites were long known to local people, they had invariably been disturbed, if not badly looted. The revelation of an ancient city in a valley in the Mosquitia mountains, of Honduras, one of the last scientifically unexplored regions on Earth, was a different story. This was the first time a large archaeological site had been discovered in a purely speculative search using a technology called LIDAR, or "light detection and ranging," which can map terrain through the thickest jungle foliage, an event I chronicled in a story for the magazine in 2013.

Rich Americans seek black market brain implants to plug into AI 'matrix'
A pair of super-rich American technology gurus are planning to undergo surgery to install experimental implants directly into their brains. The two men are currently trying to find a doctor willing to perform this untested and highly risky procedure, The Mirror has learned. If they survive the operation, the men hope to be able to directly communicate with the primitive forms of artificial intelligence currently being developed in labs across the world. But critics and conspiracy theorists fear these pioneering implants are the first step towards creating a society where every human is plugged into "the matrix". Zoltan Istvan, a U.S. Presidential candidate, personally knows both of these would-be bionic men.
