In a new study of daily ambient fine particulate matter (PM2.5) across the globe, a new study has found that only 0.18% of the global land area and 0.001% of the global population are exposed to levels of PM2.5 -- the world's leading environmental health risk factor -- below levels of safety recommended by Word Health Organization (WHO). Importantly while daily levels have reduced in Europe and...
An internal thermometer tells the seeds when to germinate
- ScienceDaily
- 23/3/7 13:32
Germination is a crucial stage in the life of a plant as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling much more vulnerable. The survival of the young plant depends on the timing of this transition. It is therefore essential that this stage be finely controlled. Botanists have now...

Researchers are looking to small towns in Iowa to understand how some support aging in place better than others. Their findings could help communities plan for the future and preserve a high quality of life for all residents.
The planet that could end life on Earth: Experiment demonstrates solar system's fragility
A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a UC Riverside experiment.
Japan's next-generation H3 rocket self-destructs after liftoff due to engine failure – video
Japan's H3 rocket, billed as a possible competitor to SpaceX's Falcon 9, self-destructed after liftoff when its second-stage engine apparently failed. It is the second H3 failure for Japan's space agency, Jaxa, after the rocket failed to leave the launchpad in a previous attempt in February. Footage taken from Jaxa's livestream shows Tuesday's launch from the Tanegashima space centre in...
Study reveals limitations in evaluating gene editing technology in human embryos
A commonly used scientific method to analyze a tiny amount of DNA in early human embryos fails to accurately reflect gene edits, according to new research led by scientists at Oregon Health & Science University.
An internal thermometer tells seeds when to germinate, researchers find
Germination is a crucial stage in the life of a plant, as it will leave the stage of seed resistant to various environmental constraints (climatic conditions, absence of nutritive elements, etc.) to become a seedling that is much more vulnerable.

This geothermal startup showed its wells can be used like a giant underground battery
In late January, a geothermal power startup began conducting an experiment deep below the desert floor of northern Nevada. It pumped water thousands of feet underground and then held it there, watching for what would happen. Geothermal power plants work by circulating water through hot rock deep beneath the surface. In most modern plants, it…
Whale-rescue experts in N.L. are showing their Canadian colleagues the ropes
Newfoundland and Labrador is a world leader in trying to save whales tangled in ocean detritus, including fishing gear, communications lines and plane debris. Now the province's whale-disentanglement experts are working to pass those skills on to...
Japan forced to destroy flagship H3 rocket in failed launch
The rocket's failure to launch is a significant blow to the country's space plans.
Pincered at sea, lobsters get new hope on land in UK
The tiny lobsters are safe from predators—including each other—as they eddy in large white plastic tanks swirling with artificial currents.
6.0-magnitude earthquake rocks southern Philippines
A 6.0-magnitude earthquake jolted the southern Philippines on Tuesday, the US Geological Survey said, but there were no reports of casualties or major damage.
Japan launches H3 rocket, destroys it over 2nd stage failure
Japan's space agency intentionally destroyed a new H3 rocket moments into its launch Tuesday after the ignition for the second stage of the country's first new rocket series in more than two decades failed.
Global food system emissions imperil Paris climate goals
The global food system's greenhouse gas emissions will add nearly one degree Celsius to Earth's surface temperatures by 2100 on current trends, obliterating Paris Agreement climate goals, scientists warned Monday.
Cartier and Tiffany are getting into AR to sell luxury to Gen Z
I recently tried on a Cartier Tank watch and a slew of Tiffany bracelets, watching the metal and diamonds shine in the dim light. I wasn’t at a store, though; I was in my bed, barefoot and in sweatpants, using an AR experience on Snap that let me see how the jewelry looked on my wrist.
The Cartier and Tiffany AR campaigns are the latest in a series of collaborations Snap is making with brands...
