Syria’s Sharaa holds phone call with Trump, Syrian presidency says
Suzanne Simard’s 1997 forest experiment did not show trees whispering to each other. It showed something narrower, stranger, and easier to test: carbon that began in the air around a paper birch seedling later appeared inside a neighbouring Douglas fir, after passing through roots and fungal tissue in the soil. The experiment, published in Nature in August 1997, used two carbon labels in the field. Paper birch and Douglas fir seedlings were sealed in plastic labelling chambers, exposed to carbon-14 dioxide or carbon-13 dioxide, left for a nine-day chase period, then harvested and analysed to see where the labelled carbon…
While tech is still leading the party, more parts of the market are starting to join in.
Stablecoin demand may soon fade, BoE’s Greene says
Students who enroll, pay housing fees, and physically live on campus are increasingly being funneled into online classes — raising a question about whether the on-campus price tag still buys an on-campus education.A CalMatters investigation found that roughly 40% of all California community college classes are now online, even though most campuses fully reopened years ago. The majority are asynchronous, meaning pre-recorded online lectures with no live instruction. Allegedly, some recordings at San Joaquin Delta College are more than a decade old.The pattern is not limited to two-year schools. The University of California and California State University systems are offering…
“The neighbor estimates damage from the tree at approximately $6,000 or more.”
Voyager 1 is currently drifting through interstellar space at roughly 38,000 miles per hour, more than 15 billion miles from the Jet Propulsion Laboratory antenna in Pasadena that still talks to it, and a radio command sent from Earth today will not arrive at the spacecraft until tomorrow evening. The light-speed delay one way is over 22 hours. A round-trip conversation, send a command and hear the acknowledgement, takes nearly two days. This means every instruction NASA transmits is, in a strict sense, aimed at a ghost. The spacecraft the engineers are commanding does not exist yet at the coordinates…
The historical claim in the lede is well documented. On 1 and 2 September 1859, a coronal mass ejection from the Sun struck Earth’s magnetosphere with such force that telegraph systems across North America, Europe, and parts of Asia and Australia were disrupted. Operators in some stations received electric shocks. Paper caught fire from sparks leaping from telegraph keys. A few stations burned. On the night of 2 September, two operators on the Boston-to-Portland line held a conversation over wires they had disconnected from their batteries, exchanging messages on what they called the auroral current alone. The forward claim in…
