Evolving complexity out of 'junk DNA'

A study by Alysha Heimberg and colleagues found that microRNAs, previously considered 'junk DNA', are diverse in primitive vertebrates like sharks and lampreys, but less common in invertebrates. This discovery suggests that microRNAs played a crucial role in the evolution of complex organs unique to vertebrates.

Why it pays to be choosy

A study published in Nature found that when individuals are choosy about their partners, cooperativeness increases and becomes more stable. This is because individuals with low cooperativeness are penalized by being left by their current partner for a more cooperative one.

Student identifies enormous new dinosaur

A new species of massive carnivorous dinosaur, Carcharodontosaurus iguidensis, has been discovered in Niger, measuring up to 13-14 meters long and 1.75 meters skull length. The fossils provide insights into the ecosystems of Africa 95 million years ago and shed light on the evolution of these ancient creatures.

Giant fossil sea scorpion bigger than man

Scientists have discovered a giant fossilized claw from an ancient sea scorpion, indicating that the creature was approximately 2.5 meters long and much taller than the average man. This finding suggests that spiders, insects, crabs, and similar creatures were larger in the past than previously thought.

The dating game

The discovery of geologic time revolutionized our understanding of the world, allowing scientists to date rocks and calculate the age of the Earth. This breakthrough, achieved by Arthur Holmes in the early 20th century, had a profound impact on fields like plate tectonics and evolution.

How dirty is your money?

Researchers from the University of Bristol and Mass Spec Analytical Ltd found that geographical location has no influence on the distribution of drug contamination on bank notes. The study analyzed £10 and £20 notes from areas across the UK, including urban and rural regions, and found that contamination levels were unrelated to location.

Ants show us how to make super-highways

Army ants form living 'plugs' to plug uneven potholes in their trails, reducing the impact on prey-laden foragers and increasing daily prey intake. The study found that specialized behavior by a minority of ant workers improves the performance of the majority, resulting in a clear benefit for the society as a whole.

Blame the brain for high blood pressure

Scientists at the University of Bristol have found that inflammation caused by trapped white blood cells can obstruct blood flow to the brain, leading to poor oxygen supply. This discovery suggests a new mechanism for high blood pressure, with potential therapeutic targets for treatment.

Females do best if they wait a while

A study by researchers at the University of Bristol found that female woodhoopoes that started breeding later in life produced more offspring than those that started earlier. The researchers attributed this to a high mortality rate among young females, suggesting they were not yet in optimal condition to breed.
