World's first CRISPR / Cas-9 control of genetic inheritance in mammals

CRISPR / Cas9 is a form of genetic engineering that is promising, such as killing cancer cells, but also contains some severe warnings, such as that it can cause DNA damage. So far, scientists have used CRISPR / Cas9 in a variety of plants and animals to process genetic information, including attempts to practice so-called "active genetics". This last approach …

Scientists discover extinct giant herbivores related to mammals

Scientists were surprised to discover a giant herbivore that lived in the Triassic period and is a relative of mammals. The creature named Lisowicia bojani was living with long-necked dinosaurs at that time. ( Pixabay | Simon Bardet ) Scientists recently discovered the remains of an elephant-sized mammal relative with features of a rhino and a turtle. This species has …

Human footprint on the extinction of mammals – News

According to a study by the University of Queensland, human impact is the biggest risk factor for the possible extinction of a quarter of all mammals on land. Researchers compared a 16-year trend in the global human footprint with extinction risk for approximately 4,500 land-based mammals. Dr. Moreno Di Marco, Adjunct Fellow of the UQ School of Earth and Environmental …

Mammals take millions of years to recover from us

The Pygmy Sloth, for example, is perhaps one of the most endangered species of mammals, but it is also one of the youngest that deviated from its closest relative 9,000 years ago. The aardvark, on the other hand, is the last survivor of a once-large mammal group that seceded from the others 75 million years ago. Losing the miniature sloth …

Why some mammals do not have testicles, but most do

Scientists have long wondered what the earliest mammalian balls look like. After all, some species live today, such as elephants, where they are safely wrapped around the kidneys. Most other mammals drop their testes under the skin – like seals – into the lower abdomen or into an extra-abdominal sac called scrotum – like humans. Which style came first was …

Biomass study finds that humans extinguish wild mammals

A team of scientists has dismantled previous studies for estimating the total mass of carbon in each group of organisms on Earth as a way to measure relative biomass. Plants harbor about 450 gigatons of 550 gigatons – or about 80 gigatons Humans find only 15 percent of the Earth's entire life form, and another 15 percent are bacteria. Humans …

People destroyed 83% of all wild mammals, study finds

Imagine all the animals on earth: lions and giraffes, monkeys, penguins and bears. All this is there, sure, but you are more likely to find cows, chickens, cows, and more cows. So, Ron Milo, a biologist at the Israeli Weizmann Institute of Science, broke a new global study for The Guardian The Work a census of life on Earth, found …
