In rare interviews, federal judges criticize Supreme Court's handling of Trump cases Ten judges tell NBC News the Supreme Court needs to explain its rulings better, with some urging Chief Justice John Roberts to do more to defend the judiciary against external criticism.

"It took Trump 10 days to create an energy crisis reminiscent of the 1970s, replace Ayatollah Khamenei with Ayatollah Khamenei, and weaken our alliances worldwide.”

Graph of award probability of R35 and R01 from NIH factbook as a function of review rank percentile. As is apparent, 2025 is a significant departure, with lower award probabilities at all scores <40 and significant departures from norm, where even being in the top 10% is no longer a nearly certain indicator of success.

The data is in: the NIH goalposts have shifted.

What were once almost certain fundable scores have become coin flips and what used to be likely grants have become aspirational, leading to fewer awards.

Another manifestation of how HHS policies have led to fewer awards and less science.

Many heat-stressed tropical insects are reaching their limits Vast study in Peru and Kenya confirms limited defenses against rising temperatures, redoubling climate concerns

Insects living in the lowland tropics have evolved to deal with brutal heat. But many of them are close to their limit, according to a massive study that assessed the heat tolerance of hundreds of species. https://scim.ag/406Y5yh

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

OMB is still trying to screw science via administrative action since they’ve been denied legislative authorization (i.e. Congress did not cut NIH budget, but this administration will still try to). Assholes.

Only the best.

Markwayne (2 names) Mullin got the job because he knew Kristi Noem was in a precarious spot, so he went on Fox News constantly last week to flatter Donald Trump.

The people of Iran must be scared out of their minds, hearing Donald Trump says he will appoint their new leader, only moments before appointing America's Stupidest Senator, Markwayne Mullins, to run Homeland Security.

A new clue to how the body detects physical force

PIEZO2β€”unlike PIEZO1β€”is tethered to the actin cytoskeleton, enabling sensory neurons to detect localized mechanical forces such as light touch.

Chart showing in many countries, people see their fellow citizens as morally good.

We asked people around the world to rate the morality and ethics of others in their country.

The U.S. is the only place we surveyed where more adults describe the morality and ethics of others living in the country as bad than good. See our full morality report here: www.pewresearch.org/...

Nature Report, Killed by Trump, Is Released Independently

Scientists and other experts were preparing an assessment of the health of nature in the US when Trump returned to the White House. He canceled the report. The researchers went ahead and compiled it on their own. This week, they released a 868-p draft for public comment and scientific review.

We are heartbroken by the passing of Emmanuel Damas in ICE custody.

We do not have any information on Mr. Damas’ specific case at this time beyond that which has been publicly reported, but we do know ICE custody.

I wish some major media outlets would do broad reports on the impact of death threats on our politics, and on who's doing them (MAGA men mostly from what I can tell), and why law enforcement appears to be doing so little about them. They are such a big (submerged) part of our politics now.

FACT SHEET: How Much Is the War in Iran Costing American Taxpayers? - Institute for Policy Studies FACT SHEET: How Much Is the War in Iran Costing American Taxpayers?

NEW: The military systems that the U.S. sent to the Iran region in recent weeks ALONE cost us nearly $60 MILLION per day β€” just a fraction of the cost of this war.

That ~$60 million could cover Medicaid for 4 million Americans per day, or SNAP for 9.5 million.

When someone says β€žScientists do not want you to knowβ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

I guess we now know why Saudi Arabia and Qatar, Iran's two biggest regional rivals, bribed Trump and his family with a 747 jet, golf development deals, and billions of dollars of investments.

In private calls over the last several weeks, Saudi Crown Prince Mohammed bin Salman (MBS) reportedly urged President Trump to attack Iran. MBS’s influence with Trump has grown as the Saudi government has invested billions in projects that personally enrich Trump and his son-in-law, Jared Kushner.

If the US-Israel attack on Iran was for deterrence, why’d they hit a girl’s elementary school, killing 165?

This is why it's not enough for Congress to just appropriate funds to scientific agencies. How the funds are or are not spent and when they are spent needs to be enforced.

The administration is playing games with our taxpayer dollars, when they should be going towards scientific innovation.
