Google announced on Thursday that it is updating the summaries of search results generated by artificial intelligence. Check out their blog post here. The company acknowledged issues with the feature, such as providing strange or inaccurate answers, and plans to limit searches that return AI-generated summaries.
Liz Reid, Google’s head of search, stated that the company has implemented restrictions on the types of searches that trigger AI Overview results, specifically excluding satire or humorous content. Google has also addressed a few cases where AI Overviews violated content policies, which occurred in a small fraction of searches.
Google introduced the AI Overview feature in the US this month, but it quickly encountered problems with misinterpreting information and using sources like The Onion and Reddit for generating answers. This led to widespread mockery and the creation of memes highlighting the tool’s failures.
Despite Google’s initial promotion of the AI Overview feature as a key part of integrating artificial intelligence into its services, the company faced criticism due to its errors. This follows a previous incident earlier this year where Google’s AI tool inserted people of color into historical images incorrectly.
In a blog post, Google explained the issues with AI Overviews, attributing errors to missing information from rare or unusual searches. The company denies deliberately manipulating the feature to produce inaccurate results.
Despite some of the viral posts originating from quirky searches, there were also concerning examples, such as an AI-generated summary perpetuating a false conspiracy theory about Barack Obama. Google has made technical improvements to address these issues.
Experts in artificial intelligence point out that Google’s AI Overview issues are indicative of broader challenges, including the reliability of AI in assessing factual accuracy and the risks of automating access to information.
Google states that user feedback indicates satisfaction with search results thanks to the AI Summary feature, but the long-term effects of the company’s AI tool changes remain uncertain. Concerns have been raised by website owners about potential impacts on traffic and revenue, as well as researchers worried about Google’s increasing control over online information.
It’s finally here. Once every 200 years, two flocks of periodical cicadas will emerge from the ground.
Across much of the US, billions of winged insects are emerging from the ground in search of a mating opportunity, but an unlucky few have been infected by a mysterious pathogen that is transforming them into flying insects. The salt shaker of death.
Are you locking the door and hiding under the covers? Before you do, hear this: Although zombie insects sound like the plot of a low-budget ’70s horror movie, they’re completely harmless to humans, plants, and pets, so feel free to marvel (probably from afar) as one of nature’s most powerful forces takes control.
Why do cicadas turn into zombies?
Cicada species live all over the planet, but the species currently abundant across the US are called “periodic cicadas,” which spend years underground as larvae before emerging as adults to mate.
Currently, two so-called “swarms” occur simultaneously in parts of the eastern U.S.: one that appears every 13 years, the other every 17. If you live in an area where this phenomenon is occurring, you’ll notice that it’s accompanied by a noise that’s louder than traffic.
The current occupation is expected to continue until the end of June, by which time most of the cicadas will have died and their eggs will have hatched and burrowed underground for another 13 to 17 years.
“One of the main reasons for this periodic emergence is to prevent predators from developing specialized ways to catch them,” says Dr. Jonathan Larson, an entomologist at the University of Kentucky. BBC Science Focus.
The only exception, Larson said, is Massospora cicadaina. “It’s likely that the disease will play a long game and remain dormant and not cause any symptoms until the cicadas emerge as adults above ground,” he said.
Once above ground, the infected cicada’s normally hollow body fills with white fungal spores and the abdomen bursts open to reveal what Larson describes as a “chalky white mass.”
Once exposed, the spores are free to infect other cicadas…

Imagine a third of your body being filled with a harmful pathogen. You might not feel too great, and for good reason. However, infected cicadas can carry on with life as normal. In fact, the fungus changes the cicada’s behavior in some pretty significant ways.
“They can continue to act normally as if they are not infected, which allows them to continue spreading the virus,” Larson explains.
What is normal cicada behavior? After 17 years (or 13) underground, all they have on their mind is finding a mate. Male cicadas shake their abdomens to attract females, hence the loud explosion. Infected males do the same, killing unsuspecting females.
But the fungus has another trick up its sleeve.
“Female cicadas flap their wings in response to the loud, boisterous calls of males,” Larson explains, “but if the males are infected, they also start flapping their wings, fooling other males into thinking they’re mating with the female.”
How cicadas manage to stay alive with so many parts of their bodies packed with spores remains a mystery, but scientists have found some clues in recent years.

For example, a study published in the journal Fungal EcologyIt turns out that the fungus produces a type of amphetamine in its mass, which is used as a powerful human stimulant. Massospora Cicadina Will it stick?
Larson explains that it’s not clear exactly how the psychoactive substances affect the cicadas, but that the insects must be stimulated in some way. “That’s the real zombification part: They’re doing their job, they’re alive, but they’re just going through the motions. The lights are on, but no one’s home,” Larson says.
Should we worry about zombies?
First, the percentage of infected insects is very small, less than 5%, but 5% out of billions or even trillions of insects is still a lot of zombies flying around.
Thankfully, this fungus is specialized for cicadas. Massospora Cicadina ‘ is just a little hint so you don’t have to worry about infecting yourself.
“Transmission tends to be very localized, so while there are hotspots, it’s not common everywhere,” Larson said.
However, if you are planning to eat cicadas, you should definitely be careful. Yes, there are a lot of people out there who eat cicadas. Spicy Popcorn Cicada RecipeIf you’re interested, however, you should definitely avoid eating infected varieties.
“If you’re catching cicadas, the infected ones will be noticeably different,” Larson says. “If some fall off and you see a whitish lump, throw it away and don’t eat it.” Who would have thought eating insects infected with a pathogenic zombie fungus would be a bad idea? Everyone would.

It can be challenging to ask for help when you need it, but you’re not alone in feeling this way.
Psychologists have studied this phenomenon for many years, as people’s reluctance to seek help has led to various high-profile failures. These failures, such as those with the Hubble Space Telescope and the Deepwater Horizon oil spill, were often worsened by key individuals not seeking assistance.
Asking for help requires bravery because it means admitting you have needs or lack knowledge in certain areas. You may fear appearing incompetent, losing control, or giving someone else credit for your efforts. However, seeking help is essential for growth and success.
Low self-esteem or anxiety can make asking for help even more challenging, as you may fear rejection. Remember, it’s okay to seek help, as no one can do everything alone. Research shows that asking for advice actually makes you appear more competent.
Studies indicate that those who help others tend to like them more, and people are often more willing to assist than you might think. Remind yourself of this the next time you need help and be thoughtful about who you ask and when.
If someone can’t help, don’t take it personally. They may be busy or unsure of how to assist. Asking for help is a normal and necessary part of life, so don’t hesitate to reach out when needed.
This article addresses the question of why it’s challenging to ask for help, posed by Sally Gardner via email.

Astronomers NIR Specs The NASA/ESA/CSA James Webb Space Telescope (Near-Infrared Spectrometer) instrument Obtained Spectrum of the record-breaking galaxy JADES-GS-z14-0, observed just 290 million years after the Big Bang. Redshift It’s about 14, a measure of how much the galaxy’s light has been stretched by the expansion of the universe.

The galaxy is much brighter than expected, with a resolved radius of 260 parsecs (848 light years).
The discovery proves that luminous galaxies were already in existence 300 million years after the Big Bang, and that they are more common than expected before Webb.
“The Webb instrument is designed to discover and understand the oldest galaxies, and in its first year of observing as part of JADES, it has found hundreds of candidate galaxies spanning the first 650 million years after the Big Bang,” said Dr. Stefano Carniani of the École Normale Supérieure in Pisa, Italy, and Dr. Kevin Hainline of the University of Arizona, Tucson.
“Early in 2023, we discovered a galaxy in our data with strong evidence of being at a redshift greater than 14. This was very exciting, but some properties of its source made us wary.”
“The source was incredibly bright, something not expected in such a distant galaxy, and it was so close to another galaxy that the two appeared to be part of a single, larger object.”
“When Webb observed the source again in October 2023 as part of the JADES Origins Field, NIR Cam (Near-infrared camera) filters further supported the high-redshift hypothesis.”
“We knew we needed a spectrum, because anything we learn would be of immense scientific importance, either as a new milestone in Webb’s study of the early universe or as a mysterious outlier in a middle-aged galaxy.”
“In January 2024, NIRSpec observed JADES-GS-z14-0 for almost 10 hours, and when the spectrum was first processed, there was unequivocal evidence that the galaxy is indeed at redshift 14.32, breaking the previous record for the most distant galaxy, JADES-GS-z13-0.”
“Seeing this spectrum was very exciting for the whole team, given that its source remained a mystery.”
“This discovery was not just a new distance record for our team. The most important thing about JADES-GS-z14-0 is that it shows that at this distance, this galaxy must be intrinsically very luminous.”
“The images show that the source is more than 1,600 light-years in diameter, proving that the light we are seeing is coming primarily from young stars, and not from the vicinity of a growing supermassive black hole.”
“This much starlight suggests that the galaxy’s mass is hundreds of millions of times that of the Sun!”
“This raises the question: How could nature create such a bright, massive and large galaxy in less than 300 million years?”
“The data reveal other important aspects of this remarkable galaxy,” the astronomers said.
“We found that the galaxy’s color is not inherently blue, which indicates that even at its very earliest stages, some of its light is being reddened by dust.”
They also confirmed that JADES-GS-z14-0 was detected at Webb’s longer wavelengths. Milli (mid-infrared observation instrument), a remarkable achievement considering its distance.
MIRI’s observations cover wavelengths of light emitted in the visible range that are redshifted and cannot be seen by Webb’s near-infrared instrument.
According to the analysis, the brightness of the source suggested by the MIRI observations exceeds that estimated from measurements by other Webb instruments, indicating the presence of strong ionized gas emission in the galaxy in the form of bright emission lines from hydrogen and oxygen.
The presence of oxygen so early in the galaxy’s life was surprising, suggesting that several generations of very massive stars had already died before the galaxy was observed.
“Taken together, all these observations show that JADES-GS-z14-0 is different from the types of galaxy predicted to exist in the early universe by theoretical models and computer simulations,” the researchers said.
“Given the observed luminosity of a source, we can predict how it will grow over cosmic time. So far, we have not found a suitable analogue among the hundreds of other galaxies we have observed at high redshifts in our survey.”
“Because the region of sky we searched to find JADES-GS-z14-0 is relatively small, its discovery has a significant impact on the predicted number of luminous galaxies seen in the early universe, as discussed in a separate, concurrent JADES study.”
“Webb’s observations will enable astronomers to discover many more such luminous galaxies over the next decade, and perhaps sooner.”
“We’re excited to see the incredible diversity of galaxies present in Cosmic Dawn!”

Vermont’s groundbreaking new law is set to become the first in the United States to mandate that fossil fuel companies contribute to the expenses associated with weather-related disasters caused by climate change.
The bill was authorized by Republican Governor Phil Scott on Thursday night without his signature, following its passage in the state Legislature with majority support from Democrats.
According to Vermont law, the Climate Superfund Act is designed to hold companies accountable, similar to the EPA’s Superfund program, by requiring large oil and high-emission companies to cover expenses related to preparing for and recovering from extreme weather events resulting from climate change.
The companies subject to taxation and the specific amounts they must pay will be determined based on a calculation of the role of climate change in Vermont’s weather disasters and the costs incurred by the state. Each company’s share will be based on their carbon dioxide emissions between 2000 and 2019.
Following the bill’s passage in Vermont, there was uncertainty among state lawmakers regarding Governor Scott’s potential veto of the legislation. In a memo to lawmakers, Scott expressed concerns about the bill’s impacts.
However, supporters of the law celebrated its enactment, viewing it as a step towards holding major polluters accountable for environmental damage. Elena Millay, vice president of the Vermont Environmental Protection Law Foundation, praised the legislation.

Lauren Hierle, executive director of Vermont Environmental Voters, highlighted the importance of the Climate Superfund in distributing cleanup costs fairly and preventing taxpayers from bearing the burden alone.
The funds collected from fossil fuel companies under the new law will go towards upgrading infrastructure, securing schools and public buildings against extreme weather, storm cleanup, and reducing public health expenses related to climate change. State agencies will determine each company’s financial obligations by 2027.
While the law is expected to face legal challenges, including potential lawsuits, critics like the American Petroleum Institute argue that the fees are unjust and damaging to the energy industry.
Other states such as Massachusetts, Maryland, and New York are also contemplating similar legislation in response to escalating climate disasters, showcasing a growing need for financial resources to support recovery efforts.
Jennifer Rushlow, a Vermont Law School professor, emphasized the significance of Vermont’s law in setting a precedent for resilient climate Superfund legislation that could be adopted by other states.
