A 'chemical cocktail' of sewage, slurry and plastic is polluting English rivers
Hatchery-raised steelhead trout have offspring that are good at gaining size under hatchery conditions but don't survive as well in streams as steelhead whose parents are wild fish, new research by Oregon State University shows.
Fibril activity may be key to a better understanding of foot-and-mouth disease
Poor water quality in English rivers is the result of chronic underinvestment and multiple failures in monitoring, governance and enforcement, a report from the UK Parliament's Environmental Audit Committee has claimed.
Shifting ocean closures best way to protect animals from accidental catch
The imaging of vanishingly tiny structures created by the foot-and-mouth disease virus could one day help scientists develop new treatments for infected animals.
Earth BioGenome Project begins genome sequencing in earnest
Accidentally trapping sharks, seabirds, marine mammals, sea turtles and other animals in fishing gear is one of the biggest barriers to making fisheries more sustainable around the world. Marine protected areas—sections of the ocean set aside to conserve biodiversity—are used, in part, to reduce the unintentional catch of such animals, among other conservation goals.
Newly discovered carbon may yield clues to ancient Mars
A global effort to map the genomes of all plants, animals, fungi and other microbial life on Earth, is entering a new phase as it moves from pilot projects to full-scale production sequencing. This new phase of the The Earth BioGenome Project, or EBP, is marked with a collection of papers published this week in Proceedings of the National Academies of Sciences, describing the project's goals,...
Shock waves, landslides may have caused 'rare' volcano tsunami: experts
NASA's Curiosity rover landed on Mars on Aug. 6, 2012, and since then has roamed Gale Crater taking samples and sending the results back home for researchers to interpret. Analysis of carbon isotopes in sediment samples taken from half a dozen exposed locations, including an exposed cliff, leave researchers with three plausible explanations for the carbon's origin—cosmic dust, ultraviolet...
Ozone pollution costs Asia billions in lost crops: study
A rare volcano-triggered tsunami sparked by the eruption of Hunga Tonga-Hunga Ha'apai in Tonga could have been caused by shock waves or shifting underwater land, experts said Monday.
Out of this world: 555.55-carat black diamond lands in Dubai
Persistently high levels of ozone pollution in Asia are costing China, Japan and South Korea an estimated $63 billion annually in lost rice, wheat and maize crops, a new study says.
Winter storm whipping northeast US with snow, thunderstorms
Auction house Sotheby's Dubai has unveiled a diamond that's literally from out of this world.
Terrorists who use the internet are less successful
A dangerous winter storm brought significant snowfall, strong thunderstorms and blustery winds to the northeastern U.S. on a holiday Monday.
US Cold War hostility towards Chinese due to the influence of Truman's nationalist beliefs, new research argues
There is too much focus on online radicalisation, says Joe Whittaker, when this is just one of the factors that make someone become a terrorist. In fact, Whittaker's research shows that terrorists who use the internet are less successful in achieving their goal than those who stay offline. He will defend his dissertation on 19 January.
Palomar survey instrument analyzes impact of Starlink satellites
Research suggests the failure of the Truman administration to pursue rapprochement with Chinese Communists before the founding of the People's Republic of China was not based on ideological distance or domestic politics, as has previously been suggested.
Fish stocks fluctuate with seawater temperature
Since 2019, SpaceX has been launching an increasing number of internet satellites into orbit around Earth. The satellite constellation, called Starlink, now includes nearly 1,800 members orbiting at altitudes of about 550 kilometers. Astronomers have expressed concerns that that these objects, which can appear as streaks in telescope images, could hamper their scientific observations.
Rare observation of a female blanket octopus in the wild
Year-to-year fluctuations in seawater temperature are partly responsible for the much slower ups and downs in the abundance of marine fish stocks. This is the conclusion from a worldwide study by Wageningen University & Research, among others. Fish biologists have observed slow fluctuations in fish stocks for centuries, but the causes remained largely unclear. This study shows that fluctuations on...
Globular cluster Messier 14 and its peculiar multiple stellar populations investigated by Hubble
Marine biologist, photographer and videographer Jacinta Shackleton, has posted a video on Instagram of a female blanket octopus (with its psychedelic cape on full display) she came across earlier this month while snorkeling in the Great Barrier Reef. In her post, she notes that the blanket octopus is very rarely seen because it normally spends its time out in the open ocean.
Improving reading skills through action video games
Using the Hubble Space Telescope (HST), astronomers have observed the globular cluster Messier 14 and its peculiar multiple stellar populations. Results of the observational campaign, published January 7 on arXiv.org, deliver important insight into the nature of this cluster.
Nanotherapy offers new hope for the treatment of Type 1 diabetes
What if video games, instead of being an obstacle to literacy, could actually help children improve their reading abilities? A team from the University of Geneva (UNIGE) has joined forces with scientists from the University of Trento in Italy to test an action video game for children, which would enhance reading skills. The results, published in the journal Nature Human Behaviour, demonstrate...
Report indicates moving rapidly from financial stress to financial comfort may be possible
Individuals living with Type 1 diabetes must carefully follow prescribed insulin regimens every day, receiving injections of the hormone via syringe, insulin pump or some other device. And without viable long-term treatments, this course of treatment is a lifelong sentence.
UK government: 4°C warming by 2100 "can't be ruled out"
If a new report from the Financial Wellness Lab of Canada at Western University is any indication, moving from a financially stressed situation to a more comfortable level in a relatively short period of time may not be an impossible feat.
Study finds national and international frameworks are imperative for implementing nature-based solutions in Asia
As required by the Climate Change Act 2008, the government has today submitted the Third UK Climate Change Risk Assessment (CCRA3) to Parliament.
A sweet breakthrough: Scientists develop recyclable plastics based on sugars
Recognized by the United Nations Framework Convention on Climate Change (UNFCCC) and the Convention on Biological Diversity (CBD), the term "nature-based solutions" (NbS) refers to those that bring together human well-being, environmental sustainability and biodiversity benefits. NbS are also key elements to post-COVID-19 pandemic recovery strategies. NbS include a variety of elements, starting...
Image: Rolling stones on Mars
Researchers from the University of Birmingham, U.K., and Duke University, U.S., have created a new family of polymers from sustainable sources that retain all of the qualities of common plastics, but are also degradable and mechanically recyclable.
Almost 800 subglacial lakes cataloged for first time in new global inventory
There's more to this image of Mars than first meets the eye: nestled in the detail of the cliff face that cuts through this scene are signs of geology in motion. Zooming in reveals several boulders that have fallen from the cliff edge, leaving small dimples in the soft material as they tumbled down-slope.
Enhanced statistical models will aid conservation of killer whales and other species
The world's first inventory of subglacial lakes has been compiled by an international team led by the University of Sheffield, providing researchers with a comprehensive directory of where the lakes are and how they are changing in a warming climate.
Ecologists need to understand wild animal behaviors in order to conserve species, but following animals around can be expensive, dangerous, or sometimes impossible in the case of animals that move underwater or into areas we can't reach easily.
