Scientists reveal the role of 'shark dandruff' in coral reef conservation

For 400 million years, shark-like fishes have prowled the oceans as predators, but now humans kill 100 million sharks per year, radically disrupting ocean food chains.

Plant eaters diversified quickly after mass extinctions to eat different kinds of plants

Researchers at the University of Bristol found that plant eaters diversified quickly after mass extinctions to eat different kinds of plants, and the ones that were able to chew harsher materials, which reflected the drying conditions of the late Triassic, became the most successful. These tougher herbivores included some of the first dinosaurs.

The history of the Amazon Basin affects the distribution of manatees

All three species of manatee now present on Earth share a common ancestor from which they split some 6.5 million years ago, when a huge lake in Amazonia, then linked to the Caribbean, was cut off from the sea.

TBI: Increased levels of immune cells promote inflammation that may worsen brain damage

Immediately after a traumatic brain injury and as long as one year later, there are increased levels of immune cells called ILCs in the brain promoting inflammation, which can worsen brain damage, scientists report.

Synthetic cannabidiol can kill bacteria that causes gonorrhoea

Synthetic cannabidiol, commonly called CBD, has been demonstrated to destroy the bacteria that cause meningitis, gonorrhea, and Legionnaires’ disease.

Using proteomics to determine how long a corpse has been underwater

In this interview, AZoLifeSciences speaks to Dr. Noemi Procopio about her latest research which involved using bone proteomics to determine the length of time a corpse had been left underwater.

Study uncovers unusual sex chromosomes of Australian iconic animals

The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually, appear as one pair of morphologically different chromosomes between sexes.

Researchers map platypus genome to understand its bizarre characteristics

Often considered the world's oddest mammal, Australia's beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live babies, sweats milk, has venomous spurs and is even equipped with 10 sex chromosomes.

Researchers reconstruct the chewing motion of an early mammal

Paleontologists at the University of Bonn (Germany) have succeeded in reconstructing the chewing motion of an early mammal that lived almost 150 million years ago.

Changes to oral microbiota affect the cardiovascular benefits of sport

Exercise plays a key role in maintaining good physical and mental health throughout life. There is an increasing amount of scientific evidence that some of the immune system and metabolism benefits provided by sport are related to the thousands of millions of bacteria that colonize the digestive tract, from the mouth to the intestines, known as microbiota.

KAUST researchers report a peculiar feeding strategy by titan triggerfish

Any Red Sea diver will have encountered colorful triggerfish along coral reefs, and some divers will have experienced the painful bite of their huge teeth if they get too close to their nesting grounds.

Biofilms of major pathogenic bacteria can deform soft surfaces

The vast majority of bacteria in the world live on surfaces by forming structures called "biofilms". These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that scientists describe them as "cities".

A new method to fish out Y chromosome molecules from microbial DNA

In 1997, the very first Neanderthal DNA sequence - just a small part of the mitochondrial genome - was determined from an individual discovered in the Neander Valley, Germany, in 1856.

Research finds gene family critical to unlocking vertebrate evolution

New University of Colorado Boulder-led research finds that the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago, documenting an important episode in evolution where new genes played a significant role in the evolution of novel traits in vertebrates.

Mathematical model shows how stability inherently arises in the brain

Whether you are playing Go in a park amid chirping birds, a gentle breeze and kids playing catch nearby or you are playing in a den with a ticking clock on a bookcase and a purring cat on the sofa, if the game situation is identical and clear, your next move likely would be, too, regardless of those different conditions.
