In a groundbreaking archaeological discovery, researchers have unearthed a sperm whale tooth at the Valencina de la Concepción-Castilleja de Guzmán site, located in the southwest of Seville, Spain. This remarkable find, dating back to the 3rd millennium BCE, is the first of its kind ever discovered on the Iberian Peninsula, shedding new light on the intricate relationship between ancient communities and the marine world. The tooth was found during an excavation in 2018, which was part of a project to build a new municipal library on a section of the Copper Age mega-site known as Nueva Biblioteca.

Recent research from physicists at The University of Arizona has unveiled a fascinating possibility: some asteroids may possess an extraordinary mass density that hints at the existence of heavy elements beyond the current periodic table. This groundbreaking study focuses on Compact Ultradense Objects (CUDOs), particularly spotlighting asteroid 33 Polyhymnia, which exhibits a mass density surpassing that of Osmium, the densest naturally occurring stable element.

The researchers were intrigued by the potential of CUDOs, which could contain elements with atomic numbers (Z) exceeding the known limits of the periodic table. Their study indicates that the mass density of asteroid 33 Polyhymnia is significantly greater than that of any familiar atomic matter, classifying it as a CUDO with an unknown composition. The implications of this discovery could reshape our understanding of the materials found in our Solar System.

In a groundbreaking development in the field of reproductive medicine, babies in the UK are now being born with DNA inherited from three individuals. This innovative procedure, known as mitochondrial donation treatment (MDT), aims to prevent the transmission of severe genetic disorders from mother to child.

Mitochondrial donation treatment is a targeted medical intervention that addresses specific health concerns rather than a step toward creating “designer babies.” The technique focuses on the mitochondria, which are the energy-producing structures within cells, and are passed down from mother to child. In cases where a mother carries genetic mutations in her mitochondrial DNA that could lead to serious health issues, MDT offers a potential solution.

The tech community is buzzing with discussions about the recently launched Galaxy Z Fold 7, particularly concerning some troubling reports from users on Reddit. Following its debut last week, several individuals have claimed to experience issues with store display units, specifically regarding the device’s ability to unfold completely.

According to these reports, some users have noticed that the Galaxy Z Fold 7 does not open fully flat, leaving a slight fold at the end. One user shared an image of a display model showing this flaw, which has raised eyebrows among potential buyers. However, it’s worth noting that not all users are experiencing this problem. In the same Reddit thread, others have reported that display models at different stores, such as Best Buy, opened perfectly flat, suggesting that the issue may not be widespread but rather a one-off circumstance.

In a groundbreaking discovery, astronomers have observed the largest black hole merger ever recorded, named GW231123. This extraordinary event was detected by the Laser Interferometer Gravitational-Wave Observatory (LIGO), which uses advanced technology to capture the faint ripples in space-time, known as gravitational waves, produced when two black holes collide.

The merger involved two black holes, each boasting a mass greater than 100 times that of our Sun. This significant finding not only marks a new milestone in the study of black holes but also poses intriguing questions about their formation and evolution.

The Seattle Mariners made a significant mark at this year’s All-Star Game held in Atlanta, showcasing a level of talent not seen since 2002. With five selections, the Mariners demonstrated their growing prowess in Major League Baseball, sending four players to represent the team at Truist Park. Notably, center fielder Julio Rodríguez, who was named as a reserve, opted out of attending the event.

Among the Mariners’ representatives were catcher Cal Raleigh, left fielder Randy Arozarena, starting pitcher Bryan Woo, and closer Andrés Muñoz. The game concluded in dramatic fashion, with the National League emerging victorious through a Home Run Derby-style tiebreaker after a thrilling 6-6 tie at the end of nine innings.

As the 2025 baseball season unfolds, the excitement surrounding the draft continues to resonate throughout the league. One name that has recently caught the attention of scouts and fans alike is Nick Dumesnil, an outfielder for the Tigers, who was selected in Round 8 despite being ranked as high as No. 118 in pre-draft evaluations.

Dumesnil’s journey to the Tigers has been anything but straightforward. After a stellar sophomore year where he showcased his hitting prowess in the Cape Cod League, expectations soared for the young athlete. Analysts had even projected him as a potential first-round pick, a testament to his skills and raw talent. However, as the draft approached, inconsistencies in his performance raised concerns about his ability to harness his power at the plate.

In a groundbreaking discovery, scientists have recovered ancient proteins from a fossilized rhinoceros tooth that dates back 24 million years. This remarkable find, unearthed in the Canadian Arctic, marks a significant advancement in the study of ancient life on Earth, as these proteins are ten times older than the oldest known DNA. The research, published on July 9, 2025, in the journal Nature, showcases the immense potential of paleoproteomics, a field that could revolutionize our understanding of prehistoric life.

In a shocking incident just days before her highly anticipated Cowboy Carter tour stop in Atlanta, unreleased music by Beyoncé was stolen from a rental vehicle. The theft, which occurred on July 8, involved hard drives containing not only unreleased songs but also crucial show plans and set lists for her performances. The vehicle was parked by her choreographer Christopher Grant and dancer Diandre Blue, who had briefly left to grab a bite at a nearby food hall.

Recent research from Rockefeller University has shed light on the complex interplay between hormones and brain circuitry that governs mating behaviors in mice, revealing fascinating insights into how these processes differ between sexes. The study, led by Nathaniel Heintz and his team, identifies a specific group of neurons in the prefrontal cortex that play a pivotal role in regulating sexual receptivity in females while suppressing mating interest in males.

At the heart of this research are the Cacna1h+ neurons located in the medial prefrontal cortex (PFC). These neurons are sensitive to oxytocin, often referred to as the “love hormone,” and ovarian hormones, which together influence sociosexual behaviors. The findings indicate that these neurons are not only responsive to hormonal changes but also integrate social cues from potential mates, orchestrating complex mating behaviors.
