By James ReganSYDNEY (Reuters) - Iron ore miners were waiting for conditions to ease before assessing damage caused by a cyclone that ripped across northwest Australia on Tuesday, closing ports and threatening mining operations in the sparsely populated Pilbara region.The key shipping ports of Dampier, Cape Lambert and Port Hedland, the world’s largest iron ore export terminal, bore the brunt of the storm after clearing dozens of iron ore freighters and evacuating staff over the weekend....

When it comes to treating attention-deficit hyperactivity disorder (ADHD) a lot of kids are getting the meds they need—but they may be missing out on other treatments. Despite clinical guidelines that urge that behavioral therapy always be used alongside medication, less than half of the children with ADHD received therapy as part of treatment in 2009 and 2010, according to the first nationally representative study of ADHD treatment in U.S. children....

Editor’s note: The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. The joint NASA-ESA Cassini space probe, exploring Saturn and her moons, has revealed extraordinary lakes and seas of liquid methane around the north pole of Titan. Scientists associated with the Cassini mission described a strange rectangular area of large seas, picked out by imaging instruments aboard the probe. Elongated lakes and seas connected by long skinny peninsulas characterize the two seas picked out in the new image....

In August 2012, John Christy, a climate scientist from the University of Alabama, Huntsville, testified to the Senate Environment and Public Works Committee that the Earth is not warming. In part, Christy’s testimony, a controversial one, was based on what he described as a problem with how surface temperatures are measured and averaged. Climate scientist Gilbert Compo’s response to that was: Well, I’ll measure those temperatures differently. So he set out to use an entirely different method to determine if the Earth’s surface temperature had increased 1....

WASHINGTON—With the third annual White House Science Fair as his backdrop, Pres. Barack Obama announced plans Monday to recruit one million new science, technology, engineering and math mentors from the private and public sectors to inspire many more students to pursue advanced educations and careers in those fields. Saying he is taking an “all-hands-on-deck approach” to STEM (science, technology, engineering and mathematics) education, Obama said that in addition to recruiting an “army of new teachers in these subject areas,” the country needs “to give the millions of Americans who work in science and technology not only the kind of respect they deserve but also new ways to engage young people....

After more than a decade of telescopic monitoring, astronomers have added two newfound worlds to a nearby planetary system already known to harbor four other planets, and one of the new discoveries looks to be the kind of place where life might be able to take hold. “Since the beginning of this hunt we’ve tried to find planets at about the size of the Earth with temperatures so that water can exist,” said one of the researchers, Steven Vogt of the University of California, Santa Cruz, in a Webcast press briefing on September 29....

Poor countries have spent just as much as rich ones – and in the case of China, more – to develop low-carbon energy, according to a study coming out this week. Its conclusions could turn the conventional wisdom about the differences among nations over mitigation efforts on its head. The report by former World Bank economist David Wheeler, who now leads the climate change division at the think tank Center for Global Development, finds that China spent 94 cents of every $10,000 of average income on clean energy between 1990 and 2008....

Bees are under attack around the world. One of their nastiest foes: small hive beetles (Aethina tumida). Native to sub-Saharan Africa, these invaders can completely destroy the hives of common honeybees, which they have been pushing around throughout the U.S. and Australia. “When [small hive beetles] invade a colony, their larval feeding and the spoilage that ensues converts the comb and honey into this lavalike substance. They make an incredible mess out of the comb and [bee] brood and everything else,” says James Cane, an entomologist at the U....

March 1963 Anxious Times “Ours is said to be the age of anxiety. But what exactly is anxiety and how can it be measured? Sigmund Freud wrote much about anxiety but was content to fall back largely on introspection and semantics for its definition. He pointed to the solid distinction in his native language between Furcht (fear) and Angst (anxiety), and most psychologists have followed him in considering anxiety to be quite different from fear....

You might not think that cosmologists could feel claustrophobic in a universe that is 46 billion light-years in radius and filled with sextillions of stars. But one of the emerging themes of 21st-century cosmology is that the known universe, the sum of all we can see, may just be a tiny region in the full extent of space. Various types of parallel universes that make up a grand “multiverse” often arise as side effects of cosmological theories....

The Human Microbiome Project revealed tens of trillions of microbes residing in and on humans. Now scientists are taking a census of plant microbes—and not just the hundreds of billions found in soils. Distinct microbial communities live inside roots, on leaves and within flowers, and all in all have an estimated three to six orders of magnitude greater genetic diversity than their plant hosts. This second genome, much like the human microbiome, provides plants access to nutrients and helps to suppress disease....

It has been a roller-coaster year for sports, and we’re nowhere near done. In recent weeks, the advent of rapid testing for COVID-19 appears to have led several college conferences, the Big Ten and Pac-12 among them, to reverse earlier decisions and declare that they’ll play a fall football season after all. Pac-12 commissioner Larry Scott went so far as to call the conference’s agreement with Quidel to provide daily rapid-results testing “a game-changer” that will give student-athletes “the opportunity to pursue their dreams....

The Lydian Stater was the official coin of the Lydian Empire, introduced before the kingdom fell to the Persian Empire. The earliest staters are believed to date to around the second half of the 7th century BCE, during the reign of King Alyattes (r. 619-560 BCE). According to a consensus of numismatic historians, the Lydian stater was the first coin officially issued by a government in world history and was the model for virtually all subsequent coinage....

FCC Chairman Tom Wheeler responded to the court ruling by holding out the possibility of appealing the decision: “We will consider all available options, including those for appeal, to ensure that these networks on which the Internet depends continue to provide a free and open platform for innovation and expression, and operate in the interest of all Americans.” The D.C. Circuit court ruled in favor of Verizon because of how the FCC had originally classified broadband providers of high-speed Internet as being exempt from “common carrier” regulations....

By Zoë Corbyn A clue to how arthropods–the group of more than a million invertebrate species that includes insects, spiders and crustaceans–evolved their distinctive jointed legs has been discovered in southwestern China.Nicknamed the “walking cactus” because of its spiny appearance, the Diania cactiformis fossil find is reported in a paper published February 23 in Nature. The animal belongs to the Lobopodia, a now-extinct group of animals resembling worms with legs, which may have been a relative of today’s velvet worms....

By Valerie Volcovici WASHINGTON, Jan 20 (Reuters) - Last year’s global average temperature was the hottest ever by the widest margin on record, two U.S. government agencies said on Wednesday, adding to pressure for deep greenhouse gas emissions cuts scientists say are needed to arrest warming that is disrupting the global climate. Data from U.S. space agency NASA and the National Oceanic and Atmospheric Administration showed that in 2015, the average temperature across global land and ocean surfaces was 1....

The European Union’s second-largest economy voted yesterday to leave it, a stunning move that toppled Britain’s prime minister and ushered in a new era of economic and political uncertainty. The British referendum to leave the European Union received nearly 52 percent of the vote. Prime Minister David Cameron confirmed in a speech this morning that the “will of the British people is an instruction that must be delivered.” “So there can be no doubt about the result,” he said....
