Un equipo de arqueólogos ha descubierto en el norte de Turquía un asentamiento de cazadores-recolectores que vivieron en la cueva Koskarlı hace aproximadamente 14.000 años. Los restos encontrados durante la primera campaña de excavaciones, realizada en 2024, confirman que el lugar fue habitado por grupos humanos durante el período Epipaleolítico, una etapa de transición entre […]
La investigación arqueológica en el antiguo santuario de Apolo en Gortina, la célebre ciudad cretense cuya legislación epigráfica marcó un hito en la historia del derecho griego, ha concluido su temporada de verano con un balance de hallazgos que consolidan la importancia del enclave como un centro religioso de primer orden durante la conformación de […]
El descubrimiento en 2016 de una gran fosa común en el antiguo cementerio de Falero, en la costa de Atenas, conmocionó a la comunidad arqueológica y al público general. Allí aparecieron los restos de 79 hombres adultos, muchos de ellos aún con grilletes metálicos, colocados en tres filas paralelas. Desde entonces, los investigadores han debatido […]
Scientists have finally created what might be the only thing that can get meatheads to eat their veggies: protein lettuce.
By literally shooting pig genes into the chloroplasts of lettuce and tobacco cells, an international team of researchers were able to grow produce that contained the animal protein myoglobin, they report in a new study published in the journal Frontiers in Plant Science.
Is this the pathway to the next ridiculous protein-infused snack? (We’re looking at you, protein popcorn.) Not quite. Instead, the scientists say their findings could pave the way to weaning ourselves off of environmentally-destructive meat.
“Our study demonstrates, for the first time, that higher plants can stably produce myoglobin, one of the key proteins responsible for many of meat’s desirable properties,” study lead atuhor Alexia Groff, a plant biotechnology researcher at Imperial College London, told ScienceAlert. “This is very relevant at a time when the demand for sustainable food production platforms is greater than ever.”
To combine pig genes with plant DNA, the researchers used a machine called a biolistic particle delivery system, or a “gene gun.” The nickname is apt: it works by firing microscopic metal particles covered in genes into their target. (Biolistic, by the way, is a portmanteau of “biological ballistics.”)
The target, this time, were the chloroplasts of lettuce and tobacco seedlings. Because of their “bacterial ancestry and their high number of copies per cell,” Groff explained in a statement about the work, “chloroplasts are generally much better at making large amounts of protein than the cell nucleus.”
Their genetic bullets hit the bullseye. In followup tests, the seedlings showed they had incorporated the pig DNA into the chloroplast genome. When the plants grew into adulthood and produced seeds, their offspring still possessed the transferred genes.
In all, the lettuce and tobacco plants yielded about 800 mg and 810 mg of myoglobin protein per kilogram of their dry weight. That’s ten times less than beef, but because growing plants is far more efficient than raising animals, the tradeoff could be worth it.
“Plant cultivation is far more resource-efficient than livestock production; consequently, plant-derived myoglobin could achieve protein yields per hectare that rival — or even potentially exceed — those of animal agriculture,” the authors wrote in the study, “whilst also benefiting from substantially lower water use and greenhouse gas emissions.”
If this gets adopted at scale, these protein-infused plants could be dried up and be used to bolster the protein in plant-based meats.
Other researchers caution that the food still needs to be proven safe to eat and sustainable to produce, but are optimistic about the findings.
“This an important advance on earlier plant and algal research. Demonstrating stable myoglobin production in plant chloroplasts, including in an edible crop, raises the possibility of using plants as scalable, low-input production platforms alongside microbial fermentation,” Rodrigo Ledesma-Amaro, director of the ICL’s Bezos Center for Sustainable Protein, said in a statement. “In the longer term, this could diversify how and where these ingredients are produced.”
In terms of demoralizing the federal workforce and demolishing the public sector, Elon Musk’s Department of Government Efficiency was a success.
In terms of actually saving money, though — its ostensible raison d’être — it was a dismal failure.
Musk vowed to slash $2 trillion in government “waste and fraud.” Then he lowered that target to $1 trillion, and behind the scenes reportedly promised Trump to save just a tenth of that figure. In the end, DOGE boasted on its website’s “Wall of Receipts” that it had saved around $215 billion — peanuts compared to its original promise.
But the actual amount of spending it slashed may be even lower than that. In a sweeping audit, the Government Accountability Office looked through the $110 billion that DOGE claimed it saved between January and July 2025, and found a trail of staggering incompetency that let loads of supposedly saved money fall through the cracks. That framing, though, could be too generous to Musk and his pimple-facedlackeys. You could also take the view that DOGE, in all likelihood, was deliberately cooking the books.
Per the GAO’s new report, released this month, DOGE claimed it terminated 13,476 contracts, but nearly 2,000 of them weren’t actually terminated. Spending-wise, about $27.4 billion of the purported savings came from these contracts that DOGE botched the terminations of.
The clumsy — or deceptive — bookkeeping didn’t end there. The receipts “includes leases identified for termination before [the group] was established,” the report states, as quoted by The Washington Post. And 108 of 264 of the leases it claimed it nixed “were already in process for termination.”
In all, the GAO found that over half of DOGE’s claimed $61 billion in contract savings couldn’t be verified or came from contracts that weren’t actually terminated. Similarly, 96 percent of the savings that it claimed came from grants couldn’t be verified by the accountability office, either.
Last August, an investigation by Politicofound that of the $52.8 billion that DOGE had claimed to save by cancelling contracts at the time, its actual savings were closer to just $1.4 billion. To calculate how it saved money, DOGE dubiously used the maximum spending limit listed on the contracts it axed, figures that in practice are much higher than what the government ends up spending.
At the time, government procurement expert Jessica Tillipman told the outlet that the practice was akin to “taking out a credit card with a $20,000 credit limit, cancelling it and then saying, ‘I’ve just saved $20,000.'”
