Jupiter: a massive, lifeless gas giant out there on the other side of the asteroid belt. It’s a behemoth, containing 2.5 times as much mass as all the other planets combined. To top it off, it’s named after the Roman God of War.
Only seven months after NASA's Oceans Melting Greenland (OMG) mission wrapped its last field campaign on the world's largest island, an OMG crew is back in Greenland to collect more data. With two or three field projects a year since 2016, no wonder OMG has made the most comprehensive measurements yet of how ocean water lapping at the undersides of Greenland's melting glaciers affects them. All that data has answered a lot of existing questions — and it's raised plenty of new ones.
On the long-running television series Star Trek, the characters were knowledge workers and did not seem to worry about food, lodging or acceptance. Theirs was an inclusive society, one that collaboratively practised sustainable innovation.
Brrr … it’s cold out there! Children are flocking to the television in hopes of hearing there will be a snow day; the bread and milk aisles at grocery stores are empty because of an impending snow storm; and utility trucks are out spraying salt or salt water on the roads.
A gigantic cavity — two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall — growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers' undersides in calculating how fast global sea levels will rise in response to climate change.
Compared to gene-edited babies in China and ambitious projects to rescue woolly mammoths from extinction, biotech trees might sound pretty tame. But releasing genetically engineered trees into forests to counter threats to forest health represents a new frontier in biotechnology.
Plastic pollution in the world’s oceans has become a global environmental crisis. Many people have seen images that seem to capture it, such as beaches carpeted with plastic trash or a seahorse gripping a cotton swab with its tail.
Is your morning coffee an espresso or a skinny latte? Is it from a darkly roasted French or Italian blend? If it’s a high quality brew, it’s almost certainly made with beans from the Arabica species (Coffea arabica), which is known for its finer flavours. Examples would be Javan coffees, Ethiopian sidamo, and the expensive Jamaican blue mountain.
If we’re serious about feeding the world’s growing population healthy food, and not ruining the planet, we need to get used to a new style of eating. This includes cutting our Western meat and sugar intakes by around 50%, and doubling the amount of nuts, fruits, vegetables and legumes we consume.
Water is becoming a scarce resource in many parts of the world. Water tables have been falling in many regions for decades, particularly in areas with intensive agriculture. Wells are going dry and there are few long-term solutions available — a common stopgap has been to drill deeper wells.
The winter holidays are a busy time for many businesses, including retail stores, grocers, liquor stores – and dry cleaners. People pull out special-occasion clothes made of silk, satin or other fabrics that don’t launder well in soap and water. Then there are all those specialty items, from stained tablecloths to ugly holiday sweaters.
Wageningen University & Research is working on a road-map to future-proof crops as part of EU-project CropBooster-P. Future crop yields will increase with optimal use of water and minerals. In addition to that nutritional value and crop quality are high on the list of targets. To feed a future population of 10 billion people and alleviate climate change these new crops need to eventually double the total world wilde food production. The great news that has been scientifically proven to be possible.
Not only is air pollution bad for our lungs and heart, it turns out it could actually be making us less intelligent, too. A recent study found that in elderly people living in China, long-term exposure to air pollution may hinder cognitive performance (things like our ability to pay attention, to recall past knowledge and generate new information) in verbal and maths tests. As people age, the link between air pollution and their mental decline becomes stronger. The study also found men and less educated people were especially at risk, though the reason why is currently unknown.
Much like Oxford English Dictionary’s “Word of the Year” competition, the international statistic is meant to capture the zeitgeist of this year. The judging panel accepted nominations from the statistical community and the public at large for a statistic they feel shines a light on today’s most pressing issues.
The Earth’s core is cooling down very slowly over time. One day, when the core has completely cooled and become solid, it will have a huge impact on the whole planet. Scientists think that when that happens, Earth might be a bit like Mars, with a very thin atmosphere and no more volcanoes or earthquakes. Then it would be very difficult for life to survive – but that won’t be a problem for several billions of years
Each time there’s a headline about driverless trucking technology, another piece is taken out of the old equation. First, an Uber/Otto truck’s safety driver went hands-off once the truck reached the highway (and said truck successfully delivered its valuable cargo of 50,000 beers). Then, Starsky Robotics announced its trucks would start making autonomous deliveries without a human in the vehicle at all.
The outer layer of the Earth, the solid crust we walk on, is made up of broken pieces, much like the shell of a broken egg. These pieces, the tectontic plates, move around the planet at speeds of a few centimetres per year. Every so often they come together and combine into a supercontinent, which remains for a few hundred million years before breaking up. The plates then disperse or scatter and move away from each other, until they eventually – after another 400-600 million years – come back together again.
NASA scientist Jeremy Harbeck was on a surveying flight over the Antarctic Peninsula earlier this month when he spotted an iceberg that looked like no other. It was almost perfectly rectangular, with square sides and a flat top that made it look more human-made than natural.
Just like a teenager wanting to be older, volcanoes can lie about their age, or at least about their activities. For kids, it might be little white lies, but volcanoes can tell big lies with big consequences.
Arctic sea ice likely reached its 2018 lowest extent on Sept. 19 and again on Sept. 23, according to NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. Analysis of satellite data by NSIDC and NASA showed that, at 1.77 million square miles (4.59 million square kilometers), 2018 effectively tied with 2008 and 2010 for the sixth lowest summertime minimum extent in the satellite record.
Earlier this year, experts feared that a drought would force the South African metropolis of Cape Town to shut off residential tap water. Cape Town would have been the first major world city to face “Day Zero.”
On the cusp of our atmosphere live a thin group of seasonal electric blue clouds. Forming 50 miles above the poles in summer, these clouds are known as noctilucent clouds or polar mesospheric clouds — PMCs. A recent NASA long-duration balloon mission observed these clouds over the course of five days at their home in the mesosphere. The resulting photos, which scientists have just begun to analyze, will help us better understand turbulence in the atmosphere, as well as in oceans, lakes and other planetary atmospheres, and may even improve weather forecasting.
There is no doubt that plastic pollution in oceans is a growing worldwide problem. The internet is full of images of seabirds and other marine animals entangled in plastic waste, and animals starve because their guts are blocked with plastic bags.
