Beneath the surface web, the public form of the internet you use daily to check email or read news articles, exists a concealed "dark web." Host to anonymous, password-protected sites, the dark web is where criminal marketplaces thrive in the advertising and selling of weapons, drugs, and trafficked persons. Law enforcement agencies work continuously to stop these activities, but the challenges they face in investigating and prosecuting the real-world people behind the users who post on these sites are tremendous.

Button batteries can rapidly damage stomach lining before symptoms appear
Damage to the lining of the stomach can occur quickly when children swallow button batteries; therefore, clinicians should consider prompt endoscopic removal, even when the child is symptom free and the battery has passed safely through the narrow esophagus, according to research presented at Digestive Disease Week (DDW) 2019. The recommendations represent a change from current practice of watching and waiting.

Here's why your internet may be delivered by a drone someday soon
As the pilotless flying wing came in for a landing, winds suddenly picked up. Facebook Inc.'s Aquila drone—powered by the sun and wider than a Boeing 737 jetliner—struggled to adjust. Just before landing, part of the right wing broke off.

Dangerous pathogens use this sophisticated machinery to infect hosts
Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3-D molecular architecture of the T4SS from the human pathogen Legionella pneumophila with unprecedented details. This could in the future enable the development of precisely targeted antibiotics for the aforementioned diseases.

Bullet train champion in Japan will debut in 2030, now being tested
Testing for a train capable of 249mph (400 kph) speeds is to happen about twice a week at night. Bloomberg said ALFA-X is the world's fastest bullet train— well, for now, it is holding that title. Japan has also been working on a maglev train.

Exploring people's perception of geometric features, personalities and emotions in videos with virtual humans
Researchers at Pontifical Catholic University of Rio Grande do Sul have recently carried out a study aimed at evaluating people's perceptions of geometric features, personalities and emotions presented in video sequences with virtual humans. Their study, outlined in a paper pre-published on arXiv, merges computer science tools with psychology research practices.

Ultra-clean fabrication platform produces nearly ideal 2-D transistors
Semiconductors, which are the basic building blocks of transistors, microprocessors, lasers, and LEDs, have driven advances in computing, memory, communications, and lighting technologies since the mid-20th century. Recently discovered two-dimensional materials, which feature many superlative properties, have the potential to advance these technologies, but creating 2-D devices with both good electrical contacts and stable performance has proved challenging.

A face-following robot arm with emotion detection
Researchers at Universitat Autònoma de Barcelona (UAB) have recently developed a face-following robotic arm with emotion detection inspired by Pixar Animation Studios' Luxo Jr. lamp. This robot was presented by Vernon Stanley Albayeros Duarte, a computer science graduate at UAB, in his final thesis.

Study finds narrowing gender gap in youth suicides
New research from Nationwide Children's Hospital finds a disproportionate increase in youth suicide rates for females relative to males, particularly in younger youth aged 10-14 years. The report, which describes youth suicide trends in the United States from 1975 to 2016, appears this week in JAMA Network Open.

Black women more likely to die of breast cancer, especially in the South
When Felicia Mahone was 27, she felt her breast and found a mass. Breast cancer had killed nearly all the women in her family—her mother, two aunts and two cousins. Her doctor, though, downplayed the lump, assuring her everything would be all right.

Lunar South Pole Atlas—a new online reference for mission planners
The Lunar and Planetary Institute (LPI), managed by Universities Space Research Association (USRA), has compiled and made available an atlas of the Moon's south pole. Given NASA's recent direction to implement Space Policy Directive-1 landing astronauts at the south pole by 2024, the LPI has compiled a series of maps, images, and illustrations designed to provide context and reference for those interested in exploring this area.

Experimental brain-controlled hearing aid decodes, identifies who you want to hear
Our brains have a remarkable knack for picking out individual voices in a noisy environment, like a crowded coffee shop or a busy city street. This is something that even the most advanced hearing aids struggle to do. But now Columbia engineers are announcing an experimental technology that mimics the brain's natural aptitude for detecting and amplifying any one voice from many. Powered by artificial intelligence, this brain-controlled hearing aid acts as an automatic filter, monitoring wearers' brain waves and boosting the voice they want to focus on.

Early dengue virus infection could 'defuse' Zika virus
"We now know for sure that Zika virus infection during pregnancy can affect the unborn foetus in such a way that the child develops microcephaly and other severe symptoms," explains Prof Felix Drexler, a virologist at Charité who has been developing diagnostic tests for Zika and other viruses at the DZIF. Just a few years ago, pictures of affected newborns were cause for worldwide dismay and perplexity. "However, what we did not understand then was that high incidence of microcephaly seemed to occur particularly in northeastern Brazil," says Drexler. Why are expecting mothers in these regions at a higher risk of developing a severe Zika-associated disease than in other regions? The scientists consequently began to search for cofactors that have an influence on whether a Zika infection during pregnancy will develop fatal consequences or not.

Virtual reality game simulates experiences with race
Video games that use virtual reality to create immersive experiences have become increasingly popular for entertainment and for research. However, the representation of race in these simulations is often shallow—and fails to go beyond physical appearance attributes like skin color.

Earliest evidence of the cooking and eating of starch
New discoveries made at the Klasies River Cave in South Africa's southern Cape, where charred food remains from hearths were found, provide the first archaeological evidence that anatomically modern humans were roasting and eating plant starches, such as those from tubers and rhizomes, as early as 120,000 years ago.
