An international team of astronomers has discovered seven potentially habitable exoplanets -- or planets outside our solar system -- that could have liquid water on their surfaces, according to a paper published Wednesday in the journal Nature. It is unclear whether any of the newly discovered planets can harbor life. However, scientists pointed out that the new planetary system orbits TRAPPIST-1, a dwarf star that is much younger than our sun and that will continue to burn for another 10 trillion years -- more than 700 times longer than the universe has existed so far. Astronomers said that is "arguably enough time for life to evolve," the article reported. TRAPPIST-1 is about 39 light-years
The clock is ticking to save Central Africa's forest elephants. Within Gabon's Minkébé National Park, poachers likely killed about 25,000 forest elephants for their ivory tusks between 2004 and 2014, according to a Duke University-led study in the journal Current Biology.
When Olympia LePoint was 6 years old, a school field trip altered her young life. The South Central, Los Angeles, native says she “became alive” as she viewed a mission control room and jet engines at the Jet Propulsion Laboratory in California, where her late grandfather was a janitor. “It was uplifting for me,” LePoint tells PEOPLE.
On Sunday, Elon Musk 's SpaceX made history, successfully completing the first commercial rocket launch from the NASA launch pad that also sent astronauts to the moon. The win comes after multiple failures for the SpaceX and Tesla (TSLA) CEO, who wants to change the way people travel and send humans to Mars. Since his childhood, books have played a crucial role in fueling Musk's ambitions.
The number of people dying from cocaine overdoses in the United States is on the rise, and a new study suggests why: People are using cocaine and opioids together. The study researchers analyzed information on people who died due to drug overdoses in the U.S. from 2000 to 2015, looking at deaths that involved just cocaine as well as those involving both cocaine and opioids. This 2015 increase occurred despite a continued drop in cocaine use since 2006, the researchers said.
South Dakota legislators are weighing whether to let teachers decide how much skepticism to work into lessons on contentious scientific topics such as evolution and climate change. A House committee on Wednesday is set to consider the measure, which would give legal protection to teachers who want to discuss "in an objective scientific manner the strengths and weaknesses" of the subjects. South Dakota is one of at least three states, along with Texas and Oklahoma, considering such a bill.
Even as northeastern Brazil suffers a devastating drought, few remember a grim chapter of a past drought when the government forced mass internment of peasants trying to flee dying farms. The first was in 1915 and the last time was between 1932 and 1933 when the authorities set up what they called concentration camps -- a fairly common term in several countries at the time and yet to be associated with the horrors of Nazi Germany. Fearing the peasants would descend in huge numbers from their parched lands into the city of Fortaleza, the government ordered thousands of families incarcerated in camps with little food, unhealthy living conditions and under guard.
Sid Miller, the state's agriculture commissioner, just approved a pesticide — called "Kaput Feral Hog Lure" — for statewide use. "The 'hog apocalypse' may finally be on the horizon," Miller said in a statement on Tuesday. Texas's agriculture commission estimates that feral hogs cause $52 million in damage each year to agricultural businesses by tearing up crops and pastures, knocking down fences and ruining equipment.
While truly large animals are not so common on land any more — most of them having been killed off by modern humans — a much bigger number of large species still thrived in the world’s oceans. But gigantism, or growing to really large sizes, was a common trait in the past since size was an obvious advantage. While dinosaurs exemplified that gigantism like nothing before or after them, it was an evolutionary characteristic found across many life forms, including worms. And a newly discovered fossil of a worm that lived in the Devonian period, about 400 million years ago, shows that its body grew in excess of a meter in length, and it had a terrifying large (relatively speaking, of course) mouth
According to the Washington Post, Donald Trump wants to make a splash in space. And he apparently wants to make that splash by orbiting the Moon. Orbiting the Moon? Merely circling it? What a comedown from America’s past high…landing twelve humans on the lunar surface. But there is a way to outdo America’s past achievements. And to accomplish this in a shorter time with a smaller budget than the Trump team imagines. It’s a way to get to the Moon and to stay there permanently. A way to begin this process immediately and to achieve moon landings in less than four years. How? Turn to private industry. Turn to two companies in particular—Elon Musk’s SpaceX and Robert Bigelow’s Bigelow Aerospace.
The planets have been nicknamed "Earth's seven sisters." Big news is that around a very nearby. Cold small star be found seven rocky earth size planet. All of which could potentially have with the water. For me it's mind blowing. The first night's what
Wednesday marks the 20th anniversary of the announcement of Dolly the sheep, the first mammal cloned from an adult cell. Her creation left a lasting impact on both the public and the field of developmental biology, experts say. At the time, other researchers had managed to clone mammals by splitting embryos in a test tube and implanting them in adults. However, none had successfully used an adult somatic (body) cell to clone a mammal. Researchers at the Roslin Institute in Scotland were finally able to produce Dolly — cloned from the udder cell of an adult sheep — after 276 attempts, according to the National Human Genome Research Institute (NHGRI). “For a developmental biologist, the ability
The six ocean hot spots that teem with the biggest mix of species are also getting hit hardest by global warming and industrial fishing, a new study finds. An international team looked at more than 2,100 species of fish, seabirds, marine mammals and even tiny plankton to calculate Earth's hot spots of marine biodiversity. "In those hot spots, the changes are already happening," says study co-author Andre Chiaradia, a senior scientist and penguin expert at the Phillip Island Nature Parks in Australia.
Johns Hopkins researchers say that in early pregnancy in mice with complete immune systems, Zika virus can cross the placenta -- intended to protect the developing fetus -- and appears to lead to a high percentage of miscarriages and to babies born with thin brain tissue and inflammation in brain cells. These findings, published Feb. 21 in Nature Communications, put scientists one step closer to developing targets for vaccines or other treatments for Zika. Currently there is no cure or treatment for the virus, which has been linked to serious neurological problems in infants whose mothers were exposed in early pregnancy. For much of 2016, Zika was considered a public health emergency by the World
The National Oceanic and Atmospheric Administration says strong atmospheric rivers can transport 7.5 to 15 times the average water flow at the mouth of the Mississippi River. These flowing columns of condensed water vapor produce "significant levels of rain and snow," and can account for 30-50% of the Pacific Coast's rain and snow.
Ivory Coast, which has seen a 90 percent decrease in its chimpanzees in just 20 years, is to host international talks in July in a bid to save the primates. Some 200 experts are due in the economic capital Abidjan from July 24 to 27 "to share experiences on chimpanzee conservation across Africa," Inza Kone, who heads a Swiss Scientific Research Centre (CSRS) in Ivory Coast, told AFP. The Wild Chimpanzee Foundation, which works to safeguard chimpanzees in west Africa, says less than 2,000 chimpanzees are left in the country compared to 12,000 in 2002.
President Donald Trump has promised to return the U.S. coal sector to its glory days. Experts say that isn't likely to happen, given the nation's shift toward natural gas and renewable energy. But if the coal sector does rebound, it'd be a boon for
Kenneth J. Arrow, a Nobel Prize-winning economist and mathematical theorist who made seminal contributions to social sciences as varied as election theory and health economics and was one of the most influential economists of his generation, died Feb. 21 at his home in Palo Alto, Calif. He was 95. His son Andrew Arrow confirmed the death, but he did not know the immediate cause. Dr. Arrow, who spent the majority of his career at Stanford University as an economics professor, was the youngest recipient of the Nobel Prize in economic sciences. He was 51 when he shared the Nobel with British economist Sir John Hicks in 1972 for their contributions to welfare economics and general equilibrium theory,
Twenty years ago, British scientists introduced the world to Dolly the Sheep - the first mammal to be cloned using nuclear transfer. She only lived for seven years, but the scientific advances that came from her creation still live on. Dolly died prematurely in 2003, after developing osteoarthritis and a lung infection, raising concerns that cloned animals may age more quickly than normal offspring. But 20 years on, researchers have allayed those fears by reporting that 13 cloned sheep, including four genomic copies of Dolly, are still in good shape at between seven and nine years of age, or the equivalent of 60 to 70 in human years. Professor Kevin Sinclair, a professor of developmental biology
Actor and singer David Cassidy recently revealed he has dementia, but what exactly does this term mean? Cassidy, who is 66, told People magazine on Monday (Feb. 20) that he has dementia, and will stop touring as a musician because of his diagnosis. The actor also said that both his mother and grandfather suffered from dementia.
It isn’t easy to marshal the will to create a human colony on Mars. It’s an expensive project, and to pull it off, you need a vision. To build that vision, the National Aeronautics and Space Administration (NASA) turned to a video game company. Blackbird Interactive, a Canadian game developer, has built an interactive art demo that illustrates NASA’s vision for a human settlement on Mars. It unveiled the demo, dubbed Project Eagle, at the DICE Summit, the elite game event in Las Vegas this week. It is the brainchild of Jeff Norris, founder and director of the Mission Operations Innovation Office at NASA’s Jet Propulsion Laboratory. He and Blackbird studied the work of the original moon exploration
To help us gain a better understanding of air quality around the world, BreezoMeter, an air quality analytics provider, is visually breaking things down with a new interactive air pollution map. The map delivers real-time information on air pollution along with hourly forecasts and helpful weather-related health and fitness recommendations. Its data is drawn from "official air quality sensors" placed across cities that monitor airborne particles and combined with information on wind, weather and traffic conditions.
Invisible particles washed off products like synthetic clothing and car tyres account for up to a third of the plastic polluting oceans, impacting eco-systems and human health, a top conservationist body warned Wednesday. In its report "Primary Microplastics in the Oceans", IUCN found that in many developed countries in North America and Europe, which have effective waste management, tiny plastic particles are in fact a bigger source of marine plastic pollution than plastic waste.
This article was originally published on The Conversation. Personalized medicine, which involves tailoring health care to each person’s unique genetic makeup, has the potential to transform how we diagnose, prevent and treat disease. After all, no two people are alike. Mapping a person’s unique susceptibility to disease and targeting the right treatment has deservedly been welcomed as a new power to heal. The human genome, a complete set of human DNA, was identified and mapped a decade ago. But genomic science remains in its infancy. According to Francis Collins, the director of the National Institutes of Health, “It is fair to say that the Human Genome Project has not yet directly affected the
Feb. 21 (UPI) -- Scientists at Kyoto University in Japan have identified another chimpanzee with trisomy 22, a Down syndrome-like chromosomal disorder. It's the second case of chimpanzee Down syndrome known to science. Healthy human cells contain a total of 46 chromosomes, 23 pairs. The cells of humans with Down syndrome feature an extra chromosome -- a third copy of chromosome 21, or trisomy 21. Apes have 48 chromosomes, one more pair than humans. When chimpanzees, gorillas or orangutans are born with an extra copy of chromosome 22, they're diagnosed with the disorder known as trisomy 22. The name of the newly diagnosed chimp is Kanako. She was born in captivity in 1992. In 2011, the facility
