When Bonnie hears the opening bars of the Verve’s Bitter Sweet Symphony, she is transported back to 1997. But it isn’t a joyful memory that comes to mind; it is the painful recollection of driving home from school and seeing the sheriff changing a lock on her house.

Then a teenager, Bonnie and her family were about to be evicted. And the Verve’s song was everywhere.

“It was a big hit at the time, and it just seemed to be playing all the time, in takeaway shops and shopping centres, on the radio in the car. I just couldn’t get away from this song,” she says.

To this day the 46-year-old who lives in Canberra, Australia, says she will change the radio or leave the location where the song is playing to avoid hearing it. “The lyrics of this song too closely described our situation,” she says.

Bitter Sweet Symphony was the recessional at my first wedding. I'm pretty certain neither of us (both trancewhore ravers) had bothered listening to the lyrics when we made that selection.

There’s a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped aluminum ion. Part of the latest wave of optical atomic clocks, it can perform timekeeping with 19 decimal places of accuracy.

Optical clocks are typically evaluated on two levels — accuracy (how close a clock comes to measuring the ideal “true” time, also known as systematic uncertainty) and stability (how efficiently a clock can measure time, related to statistical uncertainty). This new record in accuracy comes out of 20 years of continuous improvement of the aluminum ion clock. Beyond its world-best accuracy, 41% greater than the previous record, this new clock is also 2.6 times more stable than any other ion clock. Reaching these levels has meant carefully improving every aspect of the clock, from the laser to the trap and the vacuum chamber.

The team published its results in Physical Review Letters.

“It’s exciting to work on the most accurate clock ever,” said Mason Marshall, NIST researcher and first author on the paper. “At NIST we get to carry out these long-term plans in precision measurement that can push the field of physics and our understanding of the world around us.”

Indulge me in a rant. If we're going to redefine the second because of advancements in measuring sensitivity, doesn't this become a good time to reconsider the SI structure?

Bad approximations of distances in the 18th century brought us the metric system. With the sort of precision we now have, not to mention the need for nongeocentric units as space increasing becomes a field of research, why are we using a flawed system based on guesses from a few guys in France during The Enlightenment?

I've no issue with shorthand like AUs or light-years for large distances, but it feels we should have the basic tenets of the universe as the basis. Like, the light-nanosecond for distance on the human scale (it's about 11.8 inches or 29.98cm) and then reconfigure the system from first principles.

I'm not saying we should throw out measuring systems each time they get more precise, but a lot of cruft is grandfathered in to what we currently use. We can't just go for further precision and then shrug and say "well, nothing we can do about it."

Ten years ago, medical marijuana was only legal in about half of U.S. states, and recreational use was outlawed in most of the country. Today, although marijuana remains illegal at the federal level, most states have legalized some use of the drug, setting off a green rush that, according to the data platform Statista, is predicted to bring in nearly $47 billion in revenue this year.

But in the absence of regulations or guidance from the federal government, states are struggling to oversee the flood of new businesses and products. Although experts told Undark that illicit marijuana remains the bigger safety hazard, across the country, independent tests have documented rampant problems with the legal products on dispensary shelves, including overstated THC levels as well as amounts of pesticides, mold, and heavy metals that exceed state limits.

Whistleblower reports and interviews with industry insiders show how some producers seek out lenient testing labs to examine their product. Some labs, in turn, may see a boost in business if they inflate THC values and greenlight contaminated products — a pattern corroborated by Undark’s own analysis of testing data obtained through state open records laws.

More potent products sell better, said Mike Graves, a one-time major Oklahoma grower who has tangled with Parker and Hrabina. In an interview with Undark, Graves acknowledged shopping around for favorable labs: “I’d roll a joint,” he said, and would “send it out to three different companies.” He would then use whichever company returned the highest THC level to provide the required testing certification for his products.

The industry’s problem, Graves said, is lax oversight of bad labs.

Believe it or not, this is a very short excerpt. Ever since I discovered Delta 8 years ago, I won't buy anything without a CoA, but back then it was all online, and Redditors would regularly post about differing results when they sent samples off for testing.

In this way, users were regulating the market for those who knew where to look -- and, in the end, pretty much three to four distillate producers got the overall stamp of approval. That's simply not feasible in a fractured physical retail flower market.

And boards or commissions previously used to handling just alcohol have an entirely new issue on their hands, as alcohol is rather widely known for being a good disinfectant. Under a previous administration, I'd have said marijuana should have fallen under USDA testing upon federal legalization, but should both randomly happen, the current patchwork system would likely be more reliable.

I'm trying to beef up my reading agenda. Also, I prefer a broad range of scientific topics like ones offered by Scientific American.

As the 2024 U.S. presidential election unfolded, many young Americans found themselves emotionally drained—not just by the outcome, but by the long months of anticipation and constant news coverage.

Humpback whales may be trying to communicate with us, using bubbles.

For the first time, scientists from the SETI Institute and UC Davis have documented humpback whales blowing large “vortex bubble rings” that resemble “smoke” rings during calm, voluntary interactions with humans — behavior that appears unrelated to feeding, mating or defense.

“Humpback whales often exhibit inquisitive, friendly behavior towards boats and human swimmers,” said Jodi Frediani, a marine wildlife photographer and UC Davis affiliate, in a press release.

The team observed 12 separate bubble ring episodes involving 11 whales and 39 rings across the Pacific and Atlantic Oceans. Researchers say the bubble rings differ from other whale behaviors involving bubbles.

While humpbacks commonly use bubble nets to trap prey and bubble trails during mating, these bubble rings seemed to occur only during relaxed, voluntary encounters with humans — not while hunting or competing for mates.

Stephen Hawking, a British physicist and arguably the most famous man suffering from amyotrophic lateral sclerosis (ALS), communicated with the world using a sensor installed in his glasses. That sensor used tiny movements of a single muscle in his cheek to select characters on a screen. Once he typed a full sentence at a rate of roughly one word per minute, the text was synthesized into speech by a DECtalk TC01 synthesizer, which gave him his iconic, robotic voice.

But a lot has changed since Hawking died in 2018. Recent brain-computer-interface (BCI) devices have made it possible to translate neural activity directly into text and even speech. Unfortunately, these systems had significant latency, often limiting the user to a predefined vocabulary, and they did not handle nuances of spoken language like pitch or prosody. Now, a team of scientists at the University of California, Davis has built a neural prosthesis that can instantly translate brain signals into sounds—phonemes and words. It may be the first real step we have taken toward a fully digital vocal tract.

Some interesting developments here that definitely seem to advance the state of the art.

The U.S. Department of Defense will no longer provide satellite weather data, leaving hurricane forecasters without crucial information about storms as peak hurricane season looms in the Atlantic.

For more than 40 years, the Defense Department has operated satellites that collect information about conditions in the atmosphere and ocean. A group within the Navy, called the Fleet Numerical Meteorology and Oceanography Center, processes the raw data from the satellites, and turns it over to scientists and weather forecasters who use it for a wide range of purposes including real-time hurricane forecasting and measuring sea ice in polar regions.

This week, the Department of Defense announced that it would no longer provide that data, according to a notice published by the National Oceanic and Atmospheric Administration, NOAA.

Well, that's just great at the start of hurricane season.

First off, that hed is terrible. And this could have gone in either Food and Drink or Environment; for that reason, I'm splitting the baby and putting it here, as the "this" referenced is still in research phases.

Inside an anonymous building in Oxford, Riley Jackson is frying a steak. The perfectly red fillet cut sizzles in the pan, its juices releasing a meaty aroma. But this is no ordinary steak. It was grown in the lab next door.

What's strangest of all is just how real it looks. The texture, when cut, is indistinguishable from the real thing.

"That's our goal," says Ms Jackson of Ivy Farm Technologies, the food tech start-up that created it. "We want it to be as close to a normal steak as possible."

Lab-grown meat is already sold in many parts of the world and in a couple of years, pending being granted regulatory approval, it could also be sold in the UK too - in burgers, pies and sausages.

The elephant in the room is the reporter got to see it and smell it being cooked, but because of the lack of approval, couldn't speak to the taste.

Bacteria can be used to turn plastic waste into painkillers, researchers have found, opening up the possibility of a more sustainable process for producing the drugs.

Chemists have discovered E coli can be used to create paracetamol, also known as acetaminophen, from a material produced in the laboratory from plastic bottles.

“People don’t realise that paracetamol comes from oil currently,” said Prof Stephen Wallace, the lead author of the research from the University of Edinburgh. “What this technology shows is that by merging chemistry and biology in this way for the first time, we can make paracetamol more sustainably and clean up plastic waste from the environment at the same time.”

The publication of AviList today means that, for the first time ever, there is a unified global checklist of all bird species found on planet Earth.

AviList is a brand-new, complete global checklist of species and taxonomy. Containing 11,131 species, 19,879 subspecies, 2,376 genera, 252 families and 46 orders, it brings together the latest global thinking on what constitutes a species and shakes up our understanding of the avian world.

Until now, ornithologists, conservationists and birders have used a selection of global checklists, each with its own reasoning on what constitutes a specific species of bird. AviList’s unified view has been developed by the Working Group on Avian Checklists, containing representatives from BirdLife International, the Cornell Lab of Ornithology, the American Ornithological Society, the International Ornithologists’ Union IOU) and Avibase. The new checklist will replace the International Ornithological Congress and Clements lists, and will be updated annually.
