Historical facts revealing corruption and racism are only dangerous to those who are currently corrupt and racist.

if the truth is so dangerous to the current order, maybe that order needs to be dismantled

$700,000 a day for a year is $255,500,000. So it would take a hair under 40 years to use up the $10 billion.

Supreme Court strikes down affirmative action at colleges

The ruling will force colleges to reimagine hallmarks of the admissions process.

The Supreme Court ruled Thursday that colleges can't explicitly consider applicants' race in admissions, a landmark ruling that will radically transform how colleges are able to attract a diverse student body.

Why it matters: The ruling will force colleges to reimagine long-standing hallmarks of the admissions process and likely jeopardize the representation of Black and Latino students on campuses nationwide.

The ruling is the second in about a year that has upended decades of precedent.

Driving the news: The conservative-majority Supreme Court ruled 6-3 against the admissions processes at Harvard and the University of North Carolina, both of which give a little extra weight to applicants from certain underrepresented groups.

Climate crisis is coming for all of us. We need to vote for people who are not insulated from reality via donor bribes.

We need a robust EPA. The current Supreme Court wants to end the EPA and Federal power to regulate our air and water. Never forget.

Get involved. Vote.

[wilwheaton]

The air quality that is so shocking in New York is identical to the air quality I grew up with in Los Angeles. The EPA and the AQMD changed all of that, and I don't ever want anyone to have to experience what I did. It was awful. We must insist on strong environmental laws and severe penalties for those who break them. We owe it to our kids.

Researchers have long recognized how the ocean responds to seasonal changes in wind and weather. Now, data from MBARI’s long-term monitoring of ocean ecosystems is filling in the gaps in our understanding of the impacts of coastal upwelling from the surface to the abyssal seafloor. 

A new publication integrates data from three MBARI time series that have monitored the ocean’s surface, the midwater, and the deep seafloor to reveal how the signal of coastal upwelling persists throughout the water column. Upwelling brings a flood of nutrients and marine life responds quickly to the bounty of food. That impact on the biological community lasts for a long time, sometimes for years.

Scientists open door to manipulating 'quantum light'

For the first time, scientists at the University of Sydney and the University of Basel in Switzerland have demonstrated the ability to manipulate and identify small numbers of interacting photons—packets of light energy—with high correlation.

This unprecedented achievement represents an important landmark in the development of quantum technologies. It is published today in Nature Physics.

Stimulated light emission, postulated by Einstein in 1916, is widely observed for large numbers of photons and laid the basis for the invention of the laser. With this research, stimulated emission has now been observed for single photons.

Specifically, the scientists could measure the direct time delay between one photon and a pair of bound photons scattering off a single quantum dot, a type of artificially created atom.

“This opens the door to the manipulation of what we can call ’quantum light’,” Dr. Sahand Mahmoodian from the University of Sydney School of Physics and joint lead author of the research said.

Dr. Mahmoodian said, “This fundamental science opens the pathway for advances in quantum-enhanced measurement techniques and photonic quantum computing.”

Chemistry behind painting pigment (1)

Paris green (copper(II) acetate triarsenite or copper(II) acetoarsenite) is an arsenic-based organic pigment. It is named after being used to kill rats in the sewers of Paris. Because of its bright color and low price, Paris green was a popular pigment in the early 19th century when its toxicity was not found. It was widely used in clothing, candles, and wallpaper.

Painters such as Monet, Cezanne, and Van Gogh often used paris green as the pigment in their works. In the 1980s, the biochemistry department of the University of Glasgow examined Napoleon's body and found that he may die from arsenic poisoning. In the past, the green wallpaper used by the aristocracy was dyed with arsenic dyes such as Paris green. This is one of the hypotheses of how Napoleon died.
