Apple’s AirPods Pro are on sale just weeks after their release

  Apple’s AirPods Pro are on sale just weeks after their release Less than a month after Apple released its AirPods Pro, they're on sale for $235 on Amazon. That $14 savings is a little surprising. It's unusual to see these things go on sale so soon, and it might irk some of the folks who bought them at full price a couple weeks ago. Normally $249, the AirPods Pro are Apple's best and most expensive true wireless earbuds yet. They offer refined design, better sound and more features, like active noise cancellation (ANC). They add transparency mode, on-board controls and silicone ear tips. They're rated as sweatproof (IPX4), and of course, they have hands-free Siri.

The international team studied the formation of fine SOA particles from different vapours emitted from natural plants and from mixtures of manmade and natural vapours reacting in the lab. "By including this experimentally observed effect in a global air quality model, we have shown that the fine particle

Major Air Pollutants . Air pollution is a real public health and environmental problem that can lead to-among other things- global warming, acid rain, and the deterioration of the ozone layer. This chart names some common pollutants , their sources, and their effect on the environment.

It is well known that human hubbub can have a negative impact on some animals, but a new study Wednesday says the noise we make should be treated as a "major global pollutant".

"We found that noise affects many species of amphibians, arthropods, birds, fish, mammals, molluscs and reptilians," scientists at Queen's University Belfast said in the Royal Society's Biology Letters.

Human noise pervades the environment, from vehicles and industry in dense urban centres, to planes flying overhead, to ocean going vessels whose propellor is thought to interfere with whale sonar communications and may be implicated in mass beaching as the disorientated animals lose their sense of direction.

Apple Announces New Research App and 3 Major Health Studies for iPhone and Watch Users

  Apple Announces New Research App and 3 Major Health Studies for iPhone and Watch Users Here's what that means for your data, and privacy.Tech giants have long been carving their way into the health-sphere, and Apple already has a rich history in building medical-serving functions into the Apple Watch. But while Google is teaming up with health care providers and Amazon has been rumored to be innovating on how to sell generic drugs, Apple is now leveraging its position as the No. 1 smartwatch in America (Apple is said to have shipped more than 22 million units in 2018, compared to the second biggest seller, Fitbit, which shipped 5.5 million units last year, according to NPD data) to allow users to opt into scientific research.

OneNewsNow discusses a change in the rhetoric surrounding manmade pollutants with Chris Horner. The same “climate change” scientists and activists who have claimed for more than three decades that pollutants were driving the planet toward a “ global warming” cataclysm are now arguing that human

Reviewing a series of individual studies in what is known as a meta-analysis, Hansjoerg Kunc and Rouven Schmidt said the issue should be seen as the "majority of species responding to noise rather than a few species being particularly sensitive to noise."

"The interesting finding is that the species included range from little insects to large marine mammals such as whales," he Kunc told AFP.

"We did not expect to find a response to noise across all animal species."

The paper said that an animal's response to the clatter of human activity is not necessarily straightforward, and cannot be easily termed as positive or negative.

Manmade noise, for example, has been shown to interfere with the sonar detection systems that bats use to find their insect prey, making it more difficult for the flying mammals to catch insects.

Medicines pose global environmental risk, experts warn

  Medicines pose global environmental risk, experts warn Residues from billions of doses of antibiotics, painkillers and antidepressants pose a significant risk to freshwater ecosystems and the global food chain, a new analysis said Thursday. One study cited in its report estimates that 10 percent of all pharmaceuticals are potentially harmful to the environment -- including hormones, painkillers and antidepressants. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.

Air pollution is a serious issue because when the air we breathe carries pollutants , it can affect us in many ways. A variety of diseases have been linked 1. Review the lesson by asking students to recall the names of the six major air pollutants and the regions of the world where they were most prevalent.

Scientists are a step closer to understanding what controls fine particulate matter in the Earth's atmosphere after identifying new linkages between natural contaminants and with manmade pollutants .

But that may be good news for the bugs: "Potential prey may benefit directly from anthropogenic noise," the paper said.

Kunc cautioned, however, that the big picture is still one of serious disruption across the natural environment.

"In the bat example, the predator might suffer because they cannot locate their prey... but in species where potential prey rely on sound to detect predators, the prey might suffer because they might not be able to hear them early enough to escape."

Human sound pollution and the animal response to it must be seen in the context of an ecosystem, especially when considering conservation efforts, the authors note.

"Noise must be considered as a serious form of environmental change and pollution as it affects both aquatic and terrestrial species," they said.

"Our analyses provide the quantitative evidence necessary for legislative bodies to regulate this environmental stressor more effectively."

Samsung gets closer to building 'QD-OLED' TVs that rival LG's OLED .
While Samsung has become dominant in using OLED technology on mobile displays -- even Apple uses its screens for iPhones -- in TVs, the big name in OLED is its competitor, LG. LG's TVs have wowed testers with their ability to control light precisely because each pixel is self-illuminating, unlike the "QLED" branded quantum dot LCD tech Samsung relies on exclusively, which still puts LED backlights behind a filter. That could change soon,That could change soon, however, as Samsung announced in October that it's investing $11 billion by 2025 to build a plant capable of manufacturing true QLED TV screens that self-illuminate.
