Social media suggests seed oils — like canola — are bad for you. More science is saying otherwise
There's a sizzling debate on social media over seed oils, with some people adamantly claiming they are unhealthy. But new research, which expands on previous studies in this area, finds that they could reduce your risk of an early death.

Autotrophs are organisms which use pigments for photosynthesis by absorbing light at specific wavelengths. The dominant chlorophyll-a absorbs #light in the violet-blue (430nm) and red (660nm) wavelengths, but not green, which is why #algae is green. Phycocyanin, an accessory #pigment in #cyanobacteria, absorbs in those green wavelengths, so is blue in colour. This is why we can determine algae types from space.

"The brunt of the pain stems from changes at the National Institutes of Health, which provides the bulk of biomedical research funding in the United States and supports more than 300,000 researchers across the country. Since Trump’s inauguration on Jan. 20, NIH funding has dropped by more than $3 billion compared with grants issued during the same period last year, according to a review of publicly available grant data. The slowdown represents a nearly 60 percent decline in NIH funding, touching all corners of the American science establishment — and going far beyond areas that the White House has targeted for cuts, such as transgender health.

In interviews, more than a dozen scientists in fields ranging from cancer research to mental health described canceling planned studies, furloughing staff and rescinding job offers. All said that the U.S. research community has been hit with a bigger shock than the Great Recession in 2008 or the coronavirus pandemic that began in 2020, and that the resulting damage could linger for years.

“It’s already pretty dire,” said Dino Di Carlo, a UCLA bioengineering professor and entrepreneur, warning that the research pipeline and talent pool is drying up as laboratories shrink and students get turned away. He pointed to his own lab: Di Carlo said that for the first time in nearly 20 years, he is not recruiting PhD students to work with him given the funding uncertainty, and he knows other researchers making similar decisions."
