Scientists Reconstruct Africa’s Oldest Human Genomes

Credit: Depositphotos Reconstructing Ancient Genomes Researchers reconstructed the oldest human genomes from South Africa, based on the remains of two individuals who lived about 10,000 years ago, providing a deeper understanding of how the region was populated, explained one of the authors of the study on Sunday. A man and a woman whose remains researchers found in...

Octopus-Inspired Patches Offer Irritation-Free Skin Adhesion

Unlike some other experimental suction-based adhesive patches, the octopus-inspired AMOS patch should be relatively easy to produce on a commercial scaleKAUST Sensors like electrocardiogram (EEG) electrodes can be lifesaving, but the adhesive patches used to attach them can sometimes damage the skin. A new experimental medical patch tackles this problem by using octopus-inspired suckers. Unlike traditional...

New Living Plastic Breaks Down After Disposal

Credit: Depositphotos Scientists have developed a 'living plastic' that self-destructs when it starts to erode. During composting, this innovative material breaks down in just a month, whereas conventional plastics can take up to 55 days to decompose under similar conditions. This promising technology is inspired by plastic-degrading proteins, naturally produced by a type of bacteria discovered...

Scientists have Found Out Why Humans no Longer have Tails

Scientists have discovered why humans no longer have tails© iStock About 25 million years ago, an evolutionary divergence happened between our ancestors—the early humans and apes—and monkeys, leading to the loss of tails in our lineage. The specific genetic mutation behind this change, however, has been unknown until recently. In a recent study published in Nature, scientists...

Solar Panels: Key Milestones in Over 140 Years of Innovation

George Cove stands with his third solar array. From "Generating electricity by the sun's rays" Popular Electricity, volume 2, nr. 12, April 1910 "From a New York rooftop in the 1800s to their debut in space. From tales of kidnappings and bribery to a world-altering inkwell mishap… Solar panels stand as one of humanity's greatest inventions,...

Becoming a Father at Fifty Is on the Rise, Affecting Child Health

Credit: Pixabay Most are well aware that motherhood is limited by a biological clock – a reality that causes sleepless nights for many women, influences career and relationship decisions, and plays a significant role in the $819 million IVF industry. However, mature fatherhood carries its own risks, and a new study reveals that the number of...

Your Microwave Oven Hosts Its Own Microbiome

Credit: Depositphotos Extreme organisms, or "extremophiles," are known for their ability to thrive in extreme environments such as hot hydrothermal vents, freezing Antarctic ice, and deep within Earth's crust. Recently, researchers have discovered these resilient microbes in an unexpected location: microwave ovens. While previous research has uncovered unique microbial communities in appliances like dishwashers and...

Study: Blood Proteins Predict Risk of 60+ Diseases

Credit: Pixabay Research on thousands of proteins from a single drop of blood shows that these proteins can predict the onset of various diseases. The study, published on July 22 in Nature Medicine, results from an international collaboration involving GSK, Queen Mary University of London, University College London, Cambridge University, and the Berlin Institute of Health...

A Freeze-Dried Mammoth Reveals the Most Complete Ancient Genome in 3D

An exceptionally well-preserved, "freeze-dried" mammoth has allowed scientists to reconstruct its genome in three dimensions for the first time, including its chromosomes. Credit: Pixabay Scientists have created the most complete 3D reconstruction of the woolly mammoth genome, thanks to a remarkably well-preserved specimen that was "freeze-dried" immediately after death. With its DNA preserved in a...

Two New Hallucinogenic Mushrooms Found

Credit: Pixabay Two new hallucinogenic fungi species have been discovered and formally classified, adding to the approximately 140 known varieties of psychoactive gilled mushrooms. Researchers from Stellenbosch University, along with citizen mycologists, used phylogenetic and morphological analysis to confirm that the two mushrooms, Psilocybe ingeli and Psilocybe maluti, are novel species. These were found in southern...
