Wastewater pipe dig reveals 'fossil treasure trove'      (via sciencedaily.com)     Original source 

A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.

AI helps robots manipulate objects with their whole bodies      (via sciencedaily.com) 

A new AI technique enables a robot to develop complex plans for manipulating an object using its entire hand, not just fingertips. This model can generate effective plans in about a minute using a standard laptop.

Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses      (via sciencedaily.com) 

Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.

Do measurements produce the reality they show us?      (via sciencedaily.com) 

The measurement values determined in sufficiently precise measurements of physical systems will vary based on the relation between the past and the future of a system determined by its interactions with the meter. This finding may explain why quantum experiments often produce paradoxical results that can contradict our common-sense idea of physical reality.

Researchers extract ancient DNA from a 2,900-year-old clay brick, revealing a time capsule of plant life      (via sciencedaily.com)     Original source 

For the first time, a group of researchers have successfully extracted ancient DNA from a 2,900-year-old clay brick. The analysis provides a fascinating insight into the diversity of plant species cultivated at that time and place, and could open the way to similar studies on clay material from other sites and time periods.

Ancient metal cauldrons give us clues about what people ate in the Bronze Age      (via sciencedaily.com)     Original source 

Archaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).

The modern sea spider had started to diversify by the Jurassic, study finds      (via sciencedaily.com)     Original source 

An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind.

Unveiling Japan's ancient practice of cranial modification: The case of the Hirota people in Tanegashima      (via sciencedaily.com)     Original source 

Cranial modification is a form of body alteration where the head is pressed or bound to permanently deform the skull. The practice has been reported across various cultures throughout history. Researchers report that the Hirota people -- who lived on the southern Japanese island of Tanegashima between the 3rd to 7th century CE -- also conducted cranial modification, with indication that both males and females performed the practice.

Scientists explore dinosaur 'Coliseum' in Denali National Park      (via sciencedaily.com)     Original source 

Scientists have discovered and documented the largest known single dinosaur track site in Alaska. The site, located in Denali National Park and Preserve, has been dubbed 'The Coliseum' by researchers.

Evolving elegance: Scientists connect beauty and safeguarding in ammonoid shells      (via sciencedaily.com)     Original source 

With 350 million years of evolution culminating in almost two centuries of scientific discourse, a new hypothesis emerges. Researchers propose a new explanation for why ammonoids evolved a highly elaborate, fractal-like geometry within their shells. Their analysis shows that the increasing complexity of shell structures provided a distinct advantage by offering improved protection against predators.

The 'unknome': A database of human genes we know almost nothing about      (via sciencedaily.com)     Original source 

Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.

Ancient DNA reveals an early African origin of Cattle in the Americas      (via sciencedaily.com)     Original source 

Using ancient DNA, researchers have determined cattle were imported from Africa to the Americas much earlier in the process of European colonization than documented. The first records of African cattle in the Americas date back to the 1800s, leading some historians to conclude that early colonists relied entirely on a small stock of European cattle initially shipped to the Caribbean Islands. DNA from archaeological specimens pushes the introduction of African cattle back by more than 100 years.

Quantum material exhibits 'non-local' behavior that mimics brain function      (via sciencedaily.com) 

New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.

Self-supervised AI learns physics to reconstruct microscopic images from holograms      (via sciencedaily.com) 

Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.
