Japan on Sunday successfully launched a climate change monitoring satellite on its mainstay H-2A rocket, which made its final flight before it is replaced by a new flagship model designed to be more cost competitive in the global space market.

The H-2A rocket lifted off from the Tanegashima Space Center in southwestern Japan, carrying the GOSAT-GW satellite as part of Tokyo's effort to mitigate climate change. The satellite was safely separated from the rocket and released into a planned orbit about 16 minutes later.

Scientists and space officials at the control room exchanged hugs and handshakes to celebrate the successful launch, which was delayed by several days due to a malfunctioning of the rocket's electrical systems.

Keiji Suzuki, a Mitsubishi Heavy Industries official in charge of rocket launch operations, said he was more nervous than ever for the final mission of the rocket, which has been his career work. "I've spent my entire life at work not to drop H-2A rocket ... All I can say is I'm so relieved."

For years now, U.S. police departments have employed officers who are trained to be experts in detecting "drugged driving." The problem is, however, that the methods those officers use are not based on science, according to a new editorial in the Journal of Studies on Alcohol and Drugs (JSAD).

With marijuana now legal in many U.S. states, the need for reliable tests for marijuana impairment is more pressing than ever. Police can evaluate alcohol-intoxicated drivers by using an objective measure of breath alcohol results. But there is no "breathalyzer" equivalent for marijuana. The drug is metabolized differently from alcohol, and a person's blood levels of THC (the main intoxicating chemical in marijuana) do not correlate with impairment.

So law enforcement relies on subjective tactics—roadside tests and additional evaluations by police officers specially trained to be so-called drug recognition experts (DREs). These officers follow a standardized protocol that is said to detect drug impairment and is said to even determine the specific drug type, including marijuana.

The process involves numerous steps, including tests of physical coordination; checking the driver's blood pressure and pulse; squeezing the driver's limbs to determine if the muscle tone is "normal" or not; and examining pupil size and eye movements.

But while the protocol has the trappings of a scientific approach, it is not actually based on evidence that it works, said perspective author William J. McNichol, J.D., an adjunct professor at Rutgers University Camden School of Law.

Used a 12 inch bit. It's a great workout, but really sucked when we encountered tree roots with it. Tomorrow, I'm going to set some posts in concrete using the holes.

The number and diversity of insects is declining worldwide. Some studies suggest that their biomass has almost halved since the 1970s. Among the main reasons for this are habitat loss—for example through agriculture or urbanization—and climate change.

These threats have long been known. What is less well-known is how these global change drivers interact and how their effects can become even more severe that way. For example, insects that have been deprived of their natural habitat could be even more affected by higher temperatures in a new environment.

Researchers at Julius-Maximilians-Universität Würzburg (JMU) have investigated precisely this serious interaction at 179 locations throughout Bavaria. The study is part of the LandKlif research cluster, coordinated by Professor Ingolf Steffan-Dewenter within the Bavarian Climate Research Network bayklif.

They published their results in the journal Proceedings of the Royal Society B: Biological Sciences.

In 2019, Tesla set out to lower insurance rates for owners of its electric cars. The goal was simple, at least in theory: fix the broken cost of car insurance. Instead, Tesla may have broken its own calculator trying to make sense of repair costs.

See, Musk's vision of Tesla's insurance product was that traditional companies just didn't "get it." Tesla's data claims that its Full Self-Driving software has fewer accidents than a human driver. Plus, its cars are rolling computers that can collect copious amounts of data on its drivers and adjust risk based on their driving. So why wouldn't drivers get a lower rate for putting around with FSD enabled if they also happen to be a safe driver? Tesla quickly found out that despite these assumptions, it's still taking a bath on claim-related losses.

The data comes from S&P Global and shows that the automaker's insurance subsidiary took a loss ratio of 103.3 in 2024. The loss ratio, for those who don't know, is the amount of money that Tesla pays out per claim versus the money it takes in from premiums. The lower the number, the better, and break-even is a flat 100. In 2024, the rest of the industry averaged 66.1.

The Federal Trade Commission has delayed the start of a rule that aims to make the process of canceling subscriptions less of a nightmare. Last year, the FTC voted to ratify amendments to a regulation known as the Negative Option Rule, adding a new "click-to-cancel" rule that requires companies to be upfront about the terms of subscription signups and prohibits them "from making it any more difficult for consumers to cancel than it was to sign up." Surprising no one, telecom companies were not happy, and sued the FTC. While the rule was nevertheless set to be implemented on May 14, the FTC now says enforcement has been pushed back 60 days to July 14.

Some parts of the updated Negative Option Rule went into effect on January 19, but the enforcement of certain provisions were deferred to May 14 by the previous administration to give companies more time to comply. Under the new administration, the FTC says it has "conducted a fresh assessment of the burdens that forcing compliance by this date would impose" and decided it "insufficiently accounted for the complexity of compliance."

Once the July 14 deadline hits, the FTC says "regulated entities must be in compliance with the whole of the Rule because the Commission will begin enforcing it." But, the statement adds, "if that enforcement experience exposes problems with the Rule, the Commission is open to amending" it.

Intriguing match-ups in the fall elections emerged Friday as Democrats look to retain control of several seats in the Washington state Legislature.

Two Senate contests should provide a test of voters’ views on new laws, higher taxes and spending decisions pushed through by the majority Democrats over the objections of Republicans.

Races for two other legislative seats will showcase strains within the Democratic Party between its progressive and moderate factions.

Three appointed Democratic lawmakers are breathing easy. They drew no challengers before the filing window closed Friday.

This all but assures the trio — state Sens. Tina Orwall of Des Moines and Emily Alvarado of Seattle, and Rep. Brianna Thomas of West Seattle — will retain their seats for the 2026 session.

Here’s where things stood Friday. Candidates have until Monday to formally withdraw from any of the races.

A major part of NASA's nearly complete Nancy Grace Roman Space Telescope just passed a lengthy thermal test to ensure it will function properly in the space environment.

"This milestone tees us up to attach the flight solar array sun shield to the outer barrel assembly and deployable aperture cover, which we'll begin this month," said Jack Marshall, who leads integration and testing for these elements at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "Then we'll complete the remaining environmental tests for the flight assembly before moving on to connect Roman's two major assemblies and run the full observatory through testing, and then we'll be ready to launch."

Prior to this thermal testing, technicians integrated Roman's deployable aperture cover, a visor-like sunshade, into the outer barrel assembly, which will house the telescope and instruments, in January, then added test solar panels in March. They moved this whole structure into the Space Environment Simulator test chamber at NASA Goddard in April.

The National Oceanic and Atmospheric Administration has warned the National Weather Service of possible attacks from an armed conspiracy group targeting Doppler radar stations, according to a report from CNN. The group, Veterans on Patrol, is going after government radars because it believes they're being used as "weather weapons."

CNN learned of the possible attacks through NOAA emails warning NWS staff that Veterans on Patrol was planning to conduct "penetration drills on NEXRAD sites to identify weaknesses," with the ultimate goal of destroying NEXRAD. Despite its cooler-than-average name, the NWS uses NEXRAD or "Next Generation Weather Radar" for a fairly mundane purpose: detecting precipitation in the atmosphere. NEXRAD plays a vital role in locating thunderstorms and tornados, making it easier to evacuate vulnerable communities before disaster strikes.

Wildfires driven by climate change contribute to as many as thousands of annual deaths and billions of dollars in economic costs from wildfire smoke in the United States, according to a new study.

The paper, published Friday in the journal Nature Communications Earth & Environment, found that from 2006 to 2020, climate change contributed to about 15,000 deaths from exposure to small particulate matter from wildfires and cost about $160 billion. The annual range of deaths was 130 to 5,100, the study showed, with the highest in states such as Oregon and California.

“We’re seeing a lot more of these wildfire smoke events,” said Nicholas Nassikas, a study author and a physician and professor of medicine at Harvard Medical School. So he and multidisciplinary team of researchers wanted to know: “What does it really mean in a changing environment for things like mortality, which is kind of the worst possible health outcome?”
