Ancient Tablets Reveal the Early Roots of Imperial Governance

Ancient Tablets Reveal the Early Roots of Imperial Governance

Sunday, March 16, 2025 / No Comments

 

Archaeologists have uncovered hundreds of administrative tablets at Girsu (modern-day Tello, Iraq), shedding light on the Akkadian Empire’s bureaucracy. Dating back over 4,000 years (2300–2150 BC), these tablets provide some of the earliest evidence of state administration.

Girsu, once a major Sumerian city and religious center, was incorporated into the Akkadian Empire under Sargon of Akkad, the world’s first emperor. The tablets, found in a mud-brick archive, document transactions of goods like barley, fish, textiles, and beer, as well as the names and professions of officials, artisans, and high priestesses, revealing a structured society where even women held significant roles.

The records showcase the empire’s meticulous governance, detailing everything from major economic exchanges to minor incidents, such as the death of a sheep on the empire’s frontier. They also include architectural plans, canal maps, and temple records, illustrating the sophistication of urban planning and resource management.

Unlike many Akkadian-era tablets looted in the past, these were preserved in situ, allowing archaeologists to study their original context. This discovery provides new insights into how the empire maintained control over its vast territory, challenging previous assumptions about early bureaucratic systems.

The painstaking conservation of these fragile artifacts is underway at the Iraq Museum in Baghdad, with further research planned. These tablets offer a unique window into the daily workings of one of history’s first great empires, deepening our understanding of ancient governance and administration.

Total Lunar Eclipse to Grace the Night Sky on March 13-14, 2025

Total Lunar Eclipse to Grace the Night Sky on March 13-14, 2025

A total lunar eclipse will be visible across most of North America on the night of March 13-14, 2025, offering a rare celestial event for skywatchers. The eclipse, which will last 1 hour and 6 minutes, will be best observed from the western regions of the United States and Canada but will be visible from coast to coast.

This marks the first total lunar eclipse widely seen in North America in over two years. The phenomenon occurs when the Earth moves directly between the sun and the moon, casting a shadow that gives the moon a reddish hue, often referred to as a "Blood Moon."

Viewing Conditions and Timing

Observers on the West Coast will have the best conditions, as the eclipse will occur during mid-to-late evening hours. Across the Atlantic, the event will be visible at dawn on March 14, while in parts of Europe and Africa, the moon will set while still in total eclipse. In New Zealand and parts of Siberia, the eclipse will be visible as the moon rises.

The event will progress through several phases, beginning with the moon entering Earth's outer shadow, or penumbra, before moving into the umbra, where the total eclipse occurs. The moon will then gradually emerge from the shadow, returning to its usual brightness.

Scientific Significance

Lunar eclipses provide a unique opportunity for scientific observation, including studies of Earth’s atmosphere and its impact on light refraction. The color of the moon during totality can vary depending on atmospheric conditions, including the presence of dust or volcanic particles.

Astronomers and amateur skywatchers are encouraged to take advantage of this event. Observatories and astronomy groups may organize public viewing sessions, and individuals are advised to find locations with minimal light pollution for the best experience.

Public Engagement

Space enthusiasts are encouraged to document the eclipse, with Space.com inviting readers to submit photographs and observations. Those interested can send their images and comments to spacephotos@space.com.

With clear weather, the March 2025 lunar eclipse is expected to be a spectacular event, providing a rare opportunity to witness one of nature’s most striking astronomical displays.

New Breakthrough Treatment Could Cure Thousands of High Blood Pressure Cases

New Breakthrough Treatment Could Cure Thousands of High Blood Pressure Cases

A groundbreaking treatment could offer a cure for half a million people in the UK suffering from dangerously high blood pressure, a condition often referred to as a “silent killer” due to its lack of symptoms and high risk of heart attacks and strokes.

Researchers in London and Cambridge have developed a minimally invasive procedure called targeted thermal therapy (TTT) to tackle primary aldosteronism, a condition responsible for 5% of all high blood pressure cases. This condition occurs when small nodules on the adrenal glands cause excessive salt retention in the body, leading to dangerously high blood pressure levels—sometimes reaching 200/130, far above the healthy 120/80 range.

A Quick and Effective Alternative

TTT, also known as endoscopic ultrasound-guided radiofrequency ablation, works by using short bursts of heat to destroy the nodules causing excessive aldosterone production. Unlike traditional surgery to remove an entire adrenal gland, which requires general anesthesia and a hospital stay of several days, TTT takes just 20 minutes under sedation, allowing patients to go home the same day.

A recent 28-patient trial, published in The Lancet, showed promising results:

• 4 patients were able to stop taking medication entirely.
• 12 patients saw significant improvements in blood pressure or needed fewer drugs.
• The treatment successfully reduced excess aldosterone production in 75% of participants.

Transforming Lives

Professor Morris Brown, an expert in endocrine hypertension at Queen Mary University of London and Barts Health NHS Trust, believes this technique could be life-changing for many. “For years, people with this type of high blood pressure had no real alternative to daily medication or major surgery,” he said. “Now, we can remove the problem at its source with a simple procedure and some patients see their blood pressure return to normal the very next day.”

The treatment is currently being tested in a larger 110-patient trial to further assess its effectiveness.

Dr. Pauline Swift, chair of Blood Pressure UK, called the findings “very encouraging” and highlighted the potential for thousands of people to benefit from the new therapy. “High blood pressure is a leading cause of heart attacks, strokes, and kidney disease, yet it often goes unnoticed until serious complications arise,” she said.

If larger trials confirm these promising results, TTT could become a game-changer for those struggling with hypertension due to primary aldosteronism, offering them a safe, effective, and long-term solution.

Archaeologists Discover Oldest Known Bone Tools in Tanzania

Archaeologists Discover Oldest Known Bone Tools in Tanzania

Wednesday, March 5, 2025 / No Comments

 

In a groundbreaking discovery, archaeologists have uncovered 1.5 million-year-old bone tools in northern Tanzania, making them the oldest known of their kind by nearly a million years. The findings challenge previous assumptions about early human technology and cognition.

Historic Discovery in Olduvai Gorge

The tools, found in the Olduvai Gorge, were made from elephant and hippopotamus bones and show clear signs of being sharpened and shaped, likely with stone tools. The 27 bone fragments, some nearly 15 inches long, suggest that early human ancestors systematically produced these tools using techniques similar to stone toolmaking.

Previously, the earliest known bone tools dated back 250,000 to 500,000 years in Europe. This discovery, published in Nature, pushes that timeline back significantly, offering new insights into early hominin intelligence.

Cognitive Breakthrough for Early Humans

Researchers believe the tools demonstrate that early humans were capable of abstract reasoning, recognizing patterns, and applying learned techniques across different materials."This expansion of technological potential indicates advances in cognitive abilities" said Dr. Ignacio de la Torre, lead author of the study.

New Questions About Early Human Behavior

The discovery raises several questions:

• Who made these tools? While no human remains were found at the site, Homo erectus and Paranthropus boisei are believed to have lived in the region at the time.
• How were they used? While direct evidence is lacking, researchers suspect the tools were used for processing animal carcasses and crafting additional tools.
• Why were they made from bone? Some experts suggest bone was an alternative to stone, especially in areas where rocks were scarce.

Dr. Briana Pobiner, a paleoanthropologist at the Smithsonian, called the find “a signal that toolmaking was becoming an increasingly important part of our ancestors’ lives.”

This discovery reshapes our understanding of early technology and suggests that early human ancestors were far more advanced than previously thought.

Study Finds Bacterial Vaginosis Can Be Transmitted by Male Partners

Study Finds Bacterial Vaginosis Can Be Transmitted by Male Partners

/ No Comments

 

A new study has found that bacterial vaginosis (BV) can be passed to women by their male sexual partners, challenging long-standing beliefs that the condition is not a sexually transmitted infection (STI).

Published in the New England Journal of Medicine, the study suggests that treating male partners significantly reduces the risk of BV recurrence, potentially reshaping how the infection is managed.

Breakthrough Research

Australian researchers studied monogamous, heterosexual couples where the women had BV. One group received treatment for both the woman and her male partner, while another group treated only the woman.

The results were striking:

• BV returned in 35% of women whose partners were also treated.
• 63% of women in the other group—who were treated alone—saw their infection return.
• Women with treated partners also went longer without experiencing a recurrence.

The findings were so significant that the trial was halted early due to the clear benefits of treating both partners.

Challenge to Medical Guidelines

BV is one of the most common vaginal infections, affecting up to a third of reproductive-aged women. While it is known to be triggered by sexual activity, it has not traditionally been classified as an STI.

Experts say the study provides strong evidence that BV can be sexually transmitted and could lead to new treatment approaches.

Dr. Janet Wilson, a consultant in sexual health, called the research a “big step forward” and criticized the UK’s NHS website for providing “outdated and misleading” information on BV. She urged for medical guidelines to be updated in light of the findings.

With this discovery, BV treatment could soon change worldwide, offering better outcomes for millions of women.

Scientists Develop ‘e-Taste’ Device to Simulate Flavors in Virtual Reality

Scientists Develop ‘e-Taste’ Device to Simulate Flavors in Virtual Reality

Scientists have developed a groundbreaking device capable of recreating flavors digitally, a development that could transform virtual reality experiences, online shopping, and even weight management.

The device, known as e-Taste, allows users to experience the taste of food and drinks remotely. According to a study published in Science Advances, the system consists of two key components: an electronic tongue, which analyzes the chemical composition of a food or beverage, and a delivery system that recreates the taste using a mix of edible chemicals.

The device replicates five basic taste sensations—sweet, sour, salty, bitter, and umami—by precisely releasing corresponding chemicals onto the tongue. However, researchers note that certain sensations, such as spiciness and fattiness, are not yet reproducible.

In trials, participants successfully identified flavors with high accuracy, suggesting the technology could have widespread applications beyond entertainment, including biomedical research and sensory testing.

Experts believe the device marks a significant step toward integrating taste into digital experiences, though further development is needed before it can be widely adopted.

Fossil Discovery in China Reshapes the Timeline of Bird Evolution

Fossil Discovery in China Reshapes the Timeline of Bird Evolution

Saturday, March 1, 2025 / No Comments

 

A newly discovered fossil from southeastern China is rewriting the history of avian evolution, revealing that birds with modern anatomical features soared through the skies millions of years earlier than previously believed.

The fossil, named Baminornis zhenghensis, was found in Zhenghe County, Fujian province, and dates back approximately 150 million years to the Jurassic period. Published in the journal Nature, this discovery places Baminornis among the oldest known birds, alongside Archaeopteryx, the famed “first bird” fossil unearthed in Germany in 1862.

“For over 150 years, Archaeopteryx has stood alone as the only undisputed bird fossil from the Jurassic period,” said Steve Brusatte, a paleontologist at the University of Edinburgh. “This new fossil changes that.”

A Missing Link in Evolution

Though other birdlike fossils from the Jurassic have been found, scientists have long puzzled over the lack of confirmed bird specimens from that era. If Archaeopteryx was already flying, logic suggested that other birds must have existed too. The discovery of Baminornis fills this long-standing gap in the fossil record, making it the second confirmed bird from the Jurassic period.

Lead researcher Min Wang, from the Institute of Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences, called the find “very exciting.”

“These fossils fundamentally change our understanding of early bird evolution,” Wang told NBC News. “They show that birds originated much earlier than we previously thought.”

What Makes Baminornis Different?

Unlike Archaeopteryx, which had a long, reptile-like tail, Baminornis featured a pygostyle—a fused set of tail vertebrae similar to those found in modern birds. This shorter tail, a crucial aerodynamic feature, shifted the bird’s center of mass toward its wings, allowing for improved flight.

Until now, such adaptations were believed to have evolved at least 20 million years later, seen in birds like Eoconfuciusornis and Protopteryx.

“What excites me most is that Baminornis was a more advanced flyer than Archaeopteryx,” Brusatte said. “It shows that bird evolution was already in full swing during the Jurassic.”

The fossilized remains of Baminornis—found alongside numerous aquatic and semiaquatic species in what researchers are calling the “Zhenghe Fauna” collection—suggest a diverse ecosystem. So far, at least three fossils from this site appear to belong to early birds or their closest relatives, hinting at a broader range of Jurassic avian species yet to be uncovered.

Unanswered Questions

Although the fossil preserves much of Baminornis’ skeleton, its feathers were not fossilized, leaving gaps in understanding its wing structure and flight mechanics. The absence of a skull also limits knowledge about its diet.

Still, the discovery suggests that bird evolution began as early as 164 to 172 million years ago—pushing back previous estimates by millions of years.

“Baminornis tells us that birds were already diversifying in the Jurassic, developing different flight styles and adaptations,” Brusatte said.

With more fossils from the Zhenghe Fauna yet to be studied, researchers are optimistic that future discoveries will continue to reshape our understanding of how modern birds evolved from their dinosaur ancestors.
