How Americans think about artificial intelligence

Posted by in categories: employment, food, health, law, robotics/AI, transportation

Artificial intelligence (AI) is spreading through society into some of the most important sectors of people’s lives – from health care and legal services to agriculture and transportation.1 As Americans watch this proliferation, they are worried in some ways and excited in others.

In broad strokes, a larger share of Americans say they are “more concerned than excited” by the increased use of AI in daily life than say the opposite. Nearly half of U.S. adults (45%) say they are equally concerned and excited. Asked to explain in their own words what concerns them most about AI, some of those who are more concerned than excited cite their worries about potential loss of jobs, privacy considerations and the prospect that AI’s ascent might surpass human skills – and others say it will lead to a loss of human connection, be misused or be relied on too much.

But others are “more excited than concerned,” and they mention such things as the societal improvements they hope will emerge, the time savings and efficiencies AI can bring to daily life and the ways in which AI systems might be helpful and safer at work. And people have mixed views on whether three specific AI applications are good or bad for society at large.

Metamaterials Control the Shape of Water Waves

Posted by in categories: materials, physics

A water wave incident on a grooved wall is shown to be analogous to electromagnetic waves called surface plasmon polaritons.

The ability of metamaterials to steer light has enabled amazing inventions from superresolution microscopes to “invisiblity” cloaks. But the physics underlying these structures also applies to other waves, such as acoustic, seismic, and water waves. Huanyang Chen and his colleagues at Xiamen University in China have demonstrated a structure that can change the propagation of surface water waves, making a localized wave that is analogous to an electromagnetic excitation called a surface plasmon polariton [1].

Surface plasmon polaritons occur at the interface between a dielectric and a negative-permittivity material such as a metal. Generating an equivalent excitation in surface water waves requires a similar sort of interface, such as that between water and a vertical barrier. In this case, the water’s parameter that is analogous to a metal’s permittivity is its depth. Of course, it’s impossible for water to have negative depth, but using metamaterials, Chen and his colleagues engineered the boundary conditions of the waves to achieve the same effect.

Biden says no change on “strategic ambiguity” as Taiwan overshadows Quad talks

Posted by in category: policy

View insights.

TOKYO, May 24 (Reuters) — President Joe Biden on Tuesday said there was no change to a U.S. policy of “strategic ambiguity” on Taiwan, a day after he angered China by saying he would be willing to use force to defend the democratic island.

The issue of Taiwan loomed over a meeting in Tokyo of leaders of the Quad grouping of the United States, Japan, Australia and India, who stressed their determination to ensure a free and open Indo-Pacific region in the face of an increasingly assertive China — though Japanese Prime Minister Fumio Kishida said the group was not aimed at any one country.

Monkeypox goes global: why scientists are on alert

Posted by in categories: biotech/medical, military

The virus is called monkeypox because researchers first detected it in laboratory monkeys in 1958, but it is thought to transmit to people from wild animals such as rodents or from other infected people. In an average year, a few thousand cases occur in Africa, typically in the western and central parts of the continent. But cases outside Africa have previously been limited to a handful that were associated with travel to Africa or with the importation of infected animals. The number of cases detected outside of Africa in the past week alone — which is almost certain to increase — has already surpassed the total number detected outside the continent since 1970, when the virus was first found to cause disease in humans. This rapid spread is what has scientists on high alert.

But monkeypox is no SARS-CoV-2, the coronavirus responsible for the COVID-19 pandemic, says Jay Hooper, a virologist at the US Army Medical Research Institute of Infectious Diseases in Fort Detrick, Maryland. It doesn’t transmit from person to person as readily, and because it is related to the smallpox virus, there are already treatments and vaccines on hand for curbing its spread. So although scientists are concerned — because any new viral behaviour is worrying — they are not panicked.

Unlike SARS-CoV-2, which spreads through tiny air-borne droplets called aerosols, monkeypox is thought to spread from close contact with bodily fluids, such as saliva from coughing. That means a person with monkeypox is likely to infect far fewer close contacts than someone with SARS-CoV-2, Hooper says. Both viruses can cause flu-like symptoms, but monkeypox also triggers enlarged lymph nodes and, eventually, distinctive fluid-filled lesions on the face, hands and feet. Most people recover from monkeypox in a few weeks without treatment.

Sea corals are source of sought-after ‘anti-cancer’ compound

Posted by in categories: biotech/medical, chemistry, health

The bottom of the ocean is full of mysteries but scientists have recently uncovered one of its best-kept secrets. For 25 years, drug hunters have been searching for the source of a natural chemical that had shown promise in initial studies for treating cancer. Now, researchers at University of Utah Health report that easy-to-find soft corals—flexible corals that resemble underwater plants—make the elusive compound.

Identifying the source allowed the researchers to go a step further and find the animal’s DNA code for synthesizing the chemical. By following those instructions, they were able to carry out the first steps of re-creating the soft coral chemical in the laboratory.

“This is the first time we have been able to do this with any drug lead on Earth,” says Eric Schmidt, Ph.D., professor of medicinal chemistry at U of U Health. He led the study with Paul Scesa, Ph.D., postdoctoral scientist and first author, and Zhenjian Lin, Ph.D., assistant research professor.

Thought Machine CEO Paul Taylor was the brains behind Google’s text-to-speech technology. He now runs the company on the same principles learnt in his early career at Google.

An image from the Hubble Space Telescope shows an unusual interaction of four dwarf galaxies, so close together that all of them would fit within the Milky Way.
