Until now, very few DNA samples have surpassed the 100,000-year threshold due to preservation challenges. By recovering DNA from mammoth specimens spanning over more than a million years, this study showcases the importance of temporal sampling to characterize the evolutionary history of species.

By analyzing these new mitogenomes alongside over 200 previously published mammoth mitogenomes, the researchers were able to find that diversification events across mammoth lineages seem to coincide with well-described demographic changes during the Early and Middle Pleistocene.

Their findings support an ancient Siberian origin for major mammoth lineages and reveal how shifts in population dynamics might have contributed to the expansion and contraction of distinct genetic clades.

Their results confirm previous research, showing that mammoths from around a million years ago do not closely resemble later mammoths.

Hopefully that title wasn't too clickbait, here is the article and details.

Tldr:

South Africa helicopter crash blamed on penguin in cardboard box that hit pilot's controls

Everyone was ok:

The aircraft sustained substantial damage but the pilot and passengers were uninjured, according to the incident report. The penguin was also unharmed, the report noted.

How it happened:

The pilot and passengers were conducting an aerial survey flight of an island off South Africa's Eastern Cape on January 19, 2025. The helicopter safely landed on Bird Island. Before departing, one of the passengers, who the incident report referred to as a "specialist," asked that they transport one of the penguins on the island back with them. The pilot agreed, and the penguin was placed in a cardboard box.

When the helicopter was at an altitude of around 50 feet, the cardboard box slid off the passenger's lap -- onto the pilot's cyclic pitch control lever, the incident report said. The helicopter rolled to the right. The pilot could not recover, the incident report said. As the aircraft descended, the main rotor blades of the helicopter struck the ground, and the helicopter landed on its side, about 60 feet from where it had taken off.

I have been struggling with my mental health this week and seeing her really helped me. She seemed to pick up on it and was being extra playful and affectionate.

Indore in Madhya Pradesh, India, was once dotted with fetid waste dumps but after a huge campaign is now virtually spotless

This is what happens usually in India: a politician wakes up and launches a cleanliness “drive” with fanfare. They ostentatiously start sweeping a street and speak solemnly about civic duty while the media take photos. The next day it’s over and things go back to how they were before.

But not in Indore in Madhya Pradesh. From 2017, when it won the prize for being the cleanest city in the country, it kept winning for eight straight years, until last year.

Before 2017, Indore had been ranked 25th of 471 towns and cities in the government’s cleanliness rankings.

In many cities, families will keep their home scrupulously clean, but a few feet from their front door rubbish is left lying around.

“That other area is seen as someone else’s responsibility and no one sees any contradiction in walking past a stinking pile of rubbish to their clean home,” said Arjun Sehgal, a local chemistry tutor.

Residents have taken up cleanliness as their own personal responsibility, according to Prabhnit Sawhney, a petrol pump owner. “I’ve seen people stopping someone who littered. I’ve seen drivers stop their car when they see rubbish on the street to remove it. It’s become a kind of mission that inspires everyone,” he said.

As interest in nuclear power rises, startups are pursuing plans to recycle spent fuel and reuse its untapped energy to power reactors. Advocates tout new recycling methods as a breakthrough, but many experts warn it will extract plutonium that could be used for nuclear weapons.

Original Title: Study found that people who were not married were less at risk (at least 50% lower risk) than married people for dementia. One contributing factor may be that single people are better at maintaining social ties. Single people may also have a greater variety of interesting and unique experiences.

In the past few decades, several phenomena have led to excited speculation in the scientific community that they might indeed be indications that there is extraterrestrial life. It will no doubt happen again.

Recently, two very different examples sparked excitement. In 2017, it was the mystery interstellar object ‘Oumuamua. And in 2021, it was the possible discovery of the gas phosphine in the clouds of Venus.

In both cases, it seemed possible that the phenomenon indicated some kind of extraterrestrial biological source. Notably, physicist Avi Loeb from Harvard University argued in favour of the oddly shaped ‘Oumuamua being an alien spaceship.

And phosphine in the atmosphere of a rocky planet is proposed to be a strong signature for life, as it is continuously produced by microbes on Earth.

These are just two of the latest cases of a long list of examples of such initially promising phenomena. But although a few of the examples are still controversial, most have turned out to have other explanations (it wasn’t aliens).

So how can we be sure we’ve come to the right conclusion for something as subtle as the presence of a certain gas or a strange looking space rock?
