The clearest picture yet of LUCA suggests it was a relatively complex organism living 4.2 billion years ago, a time long considered too harsh for life to flourish.
A survey of 100 researchers in animal behavior, conducted by Marcela Benítez and colleagues from Emory University and published in the journal Royal Society Open Science, has provided insights into current scientific views on animal emotions and consciousness. The survey reflects a growing acceptance of these capacities in a wide range of animals, highlighting the evolving perspectives in the field of animal behavior.
| Animal Group | Percentage Believing in Emotions |
|-----------------------|----------------------------------|
| Non-human primates | 98% |
| Other mammals | 89% |
| Birds | 78% |
| Cephalopods | 72% |
| Fish | 53% |
| Insects | 67% |
| Other invertebrates | 71% |
The survey suggests a significant shift in scientific thought, with a majority of researchers now attributing emotions to a wide range of animals, even those previously considered less sentient. This indicates a growing acceptance of the complexity and depth of animal emotional experiences, likely influenced by recent research in animal cognition and emotions.

A recent study proposes that the universe functions as a vast quantum gravity computer, processing information at the Planck scale at an incredible rate, potentially influencing how physicists view cosmic interactions and energy conservation.
Archaeologists have discovered an ancient human settlement in Tajikistan that dates back approximately 150,000 years.
Archaeologists from the Hebrew University of Jerusalem and the National Academy of Sciences of Tajikistan have discovered a multi-layered archaeological site in the Zeravshan Valley of Tajikistan. The site, named Soii Havzak, contains artifacts dating back as far as 150,000 years, making it a significant find for understanding early human settlements and migrations in Central Asia.
The discovery suggests that the Zeravshan Valley, known historically as a Silk Road route, was an important migration corridor for human species like Homo sapiens, Neanderthals, and Denisovans.

The study investigates how well bacterial spores maintain their structural and morphological biosignatures after exposure to harsh conditions simulating the surfaces of Enceladus and Europa. It finds that spore structure remains resilient even after exposure to radiation and temperature extremes, suggesting that methods targeting cell morphology could be valuable for future life detection missions.
Yizhi 'Patrick' Cai of the University of Manchester is coordinating a global effort to write a complete synthetic yeast genome. The resulting cell would be the artificial life most closely related to humans to date.
A study by Professor Ella Been and Dr. Omry Barzilai sheds new light on the burial practices of Homo sapiens and Neanderthals in the Levant region during the Middle Paleolithic, revealing both similarities and differences in how these two species treated their dead.
Jericho, known as the oldest inhabited city in the world, has a rich history dating back over 11,000 years. UNESCO recently recognized its historical importance. Archaeological excavations have revealed significant findings, including the Tower of Jericho and prehistoric houses.
* Jericho, with over 11,000 years of history, is the oldest inhabited city in the world.
* UNESCO recognized Jericho's historical importance in 2023 by inscribing it on the World Heritage List.
* Archaeological excavations at Tell es-Sultan, led by Kathleen Kenyon in the 1950s, uncovered significant findings, including the Tower of Jericho.
* The ancient city of Jericho, situated in the Judean desert, offers a unique glimpse into the earliest human civilizations, with around 70 prehistoric houses and over 20 successive settlements.
* The city's transition from a nomadic lifestyle to a sedentary one, with the development of agriculture and food technologies, marked a significant evolution in human history.
* Notable archaeological discoveries in Jericho include ceramic utensils with prehistoric inscriptions, skulls with gypsum and shells, and the ruins of Tell es-Sultan, which provide insight into life in antiquity.

Within the last 200 years, we’ve discovered about two dozen species of hominins in Europe, Africa, and Asia—which you can see laid out in this map.
A study published by a multidisciplinary team of researchers proposes that the wheel originated in Neolithic mines of the Carpathian Mountains around 3900 B.C. The study, based on computational mechanical analysis, outlines a three-phase technological evolution of the wheel from free rollers to fixed-axle wheel design.
