Researchers have found that medieval activities contributed to two massive tsunamis at Lake Iseo in Italy, and they warn that similar events could happen again. A study published in Nature Communications combined data from sediment cores, seismic profiles, and historical records to model these disasters.

As human land use intensified after the fall of the Roman Empire, deforestation and increased sediment flow steepened the lake's underwater banks. In 1117 CE, an earthquake triggered a landslide, causing waves over 50 meters high that flooded nearby areas within minutes. A similar event occurred in 1222 CE, with waves reaching 13 meters.

Today, the lake's shores are densely populated, and the sediment buildup since those medieval tsunamis raises concerns about potential future disasters. The study suggests that human-driven erosion is increasing worldwide, making such catastrophic failures more likely.

Scientists generate vast amounts of research data, but connecting information across studies can be difficult. The NIH Common Fund Data Ecosystem is working to change that by making research data sets from 18 NIH programs easier to find, connect and analyze.

Scientists from Skoltech, together with colleagues from the Kharkevich Institute for Information Transmission Problems of the Russian Academy of Sciences, Lomonosov Moscow State University and other organizations, conducted a comparative study of the 3D genome organization in neurons derived from induced pluripotent stem cells and in neurons of the adult human brain.

Imagine shuffling a deck of cards where some of the cards are fading just because of the way they interact with the external environment as you shuffle them. Your job is to figure out the interplay between the shuffling, or "imposed randomness," due to the way you shuffle your cards and how that relates to the fading as cards are exposed to the external environment.

Eighty-eight years after the murder of British archaeologist James Starkey, new archival research has shed light on the mystery surrounding his death. Starkey was shot while traveling from Lachish to Jerusalem in 1938, and historians have been piecing together the events ever since. Recent findings suggest that his murder was politically motivated, tied to the tensions between Jewish and Arab communities during that period.

The evidence points to a specific group that may have been responsible for the attack, highlighting the complex landscape of pre-war Palestine. Starkey’s work had implications for both communities, and his research was seen as controversial by some. This new perspective not only clarifies who may have been behind the shooting but also emphasizes the broader historical context of conflict in the region.

While this discovery doesn’t bring closure to the case, it certainly adds depth to our understanding of Starkey’s life and the dangerous environment in which he worked. The researchers hope that these insights will encourage further investigation into other unsolved historical mysteries from that era.

Australia's redfish, a species facing serious overfishing issues, has been reclassified as "conservation dependent." This label acts as a loophole, meaning it can still be caught and sold, despite being on the brink of critical endangerment. The reclassification allows the fishing industry to continue exploiting this fish, raising concerns among conservationists who argue that it undermines efforts to protect vulnerable marine life. Critics are worried that this decision will enable ongoing overfishing and threaten the species further. The situation highlights the complexities of conservation policies and the need for stricter regulations to genuinely protect endangered marine species.

In the latest episode of VisionQuest, titled “Immolation,” we dive deeper into the origins of AI in the Marvel Cinematic Universe. The episode reveals that the initial AI technology was created by Josephine Carrington and Katerina Wells, but it also introduces a significant twist. Flashbacks show Phineas Horton, played by Paul Bettany, as one of the original creators of artificial lifeforms, linking him to the history of robotics in the MCU.

However, the biggest revelation is the introduction of a character known as TK, a human version of Ultron, portrayed by James Spader. This character is revealed to be a partner of Carrington in the creation of the AI tech sold to Tony Stark. The episode hints at a deeper connection between Vision and Ultron, suggesting that Ultron is not just a villain but also a pivotal figure in Vision's creation.

As the narrative unfolds, it becomes clear that the roots of AI in this universe are more complex than previously thought, intertwining human and synthetic elements in a way that adds layers to the story. The episode leaves us with lingering questions about TK and his role, but it’s evident that Ultron's influence runs deeper than we realized.

A recent study suggests that around 75% of deceased NFL players had chronic traumatic encephalopathy (CTE), a degenerative brain disease linked to repeated head injuries. This research builds on earlier findings, like the 2017 study that reported CTE in 99% of examined brains, but those results were limited due to selection bias—mostly players with symptoms donated their brains for study.

The new study analyzed data from 1,712 former NFL players who died between 2008 and 2021, adjusting for that bias. They found that while 74.5% of deceased players had CTE at the time of death, this doesn’t mean all former players will develop dementia. Researchers emphasize that there are ways to improve cognitive health and quality of life for players, especially those in midlife.

Looking ahead, the team plans to investigate CTE prevalence in younger players at high school and college levels, though they acknowledge the challenges in gathering that data. Overall, while the findings are concerning, there's a focus on prevention and better brain health strategies.

Meet Aria, Mila, Dave and Amar – the first four models coming out of Las Vegas-based humanoid company Realbotix. To make them more affordable than what consumers are likely to have to pay for ambulatory humanoids for at least a few years, the makers have decided to focus on the top half.

Want more engagement on social media? Stop repeating yourself. Just don't change who you are in the process. That's according to new Case Western Reserve University research suggesting that public figures can increase engagement by varying their topics and wording while "maintaining a consistent psychological voice."
