When dinosaurs went extinct, many animals literally came out of the dark

When dinosaurs went extinct, many animals literally came out of the dark
The demise of dinosaurs was good news for mammals, whose numbers exploded in the aftermath. Now, a new study suggests that the behavior of mammals changed rapidly as well, as the first of our furry ancestors began venturing out in the daylight after living a primarily nocturnal existence. The switch may have even sparked the…

Breast cancer genetics revealed: 72 new mutations discovered in global study

Breast cancer genetics revealed: 72 new mutations discovered in global study
The genetic causes of breast cancer just got clearer. Researchers from 300 institutions around the world combined forces to discover 72 previously unknown gene mutations that lead to the development of breast cancer. Two studies describing their work published Monday in the journals Nature and Nature Genetics. The teams found that 65 of the newly identified genetic variants…

Africa’s deadliest rapids give birth to new fish species

Africa’s deadliest rapids give birth to new fish species
The world’s largest and deadliest rapids are also crucibles of life. According to a new study, the final stretch of Africa’s Congo River—which packs five times the water flow of the Mississippi River into just 320 kilometers—has likely given birth to several new fish species since it formed some 5 million years ago. That’s impressive,…

New study suggests insect populations have declined by 75% over 3 decades

New study suggests insect populations have declined by 75% over 3 decades
A new scientific study has found "dramatic" and "alarming" declines in insect populations in areas in Germany, which researchers say could have far-reaching consequences for the world's crop production and natural ecosystems. The study, published on Wednesday in peer-reviewed journal PLOS One has found that, in German nature reserves, flying insect populations have declined by…

New gene variants reveal the evolution of human skin color

New gene variants reveal the evolution of human skin color
Most people associate Africans with dark skin. But different groups of people in Africa have almost every skin color on the planet, from deepest black in the Dinka of South Sudan to beige in the San of South Africa. Now, researchers have discovered a handful of new gene variants responsible for this palette of tones.…

US scientists awarded Nobel in medicine for body clock insights

US scientists awarded Nobel in medicine for body clock insights
Three US scientists have won the Nobel Prize in Physiology or Medicine "for their discoveries of molecular mechanisms controlling the circadian rhythm," otherwise known as our biological clock, the Nobel committee said. Jeffrey C. Hall, Michael Rosbash and Michael W. Young were awarded the prize for their research on how plants, humans and animals adapt…

Gene editing of human embryos in UK reveals new fertility clue

Gene editing of human embryos in UK reveals new fertility clue
The DNA of human embryos has been altered and studied for the first time in the UK, offering new insight into the early stages of human development. Scientists at the Francis Crick Institute, a medical research center, have identified the role of a key gene that controls how embryos form during the first few days…

Reconstructing how Neanderthals grew, based on an El Sidrón child

Reconstructing how Neanderthals grew, based on an El Sidrón child
How did Neanderthals grow? Does modern man develop in the same way as Homo neanderthalensis did? How does the size of the brain affect the development of the body? A study led by the Spanish National Research Council (CSIC) researcher, Antonio Rosas, has studied the fossil remains of a Neanderthal child's skeleton in order to establish whether…
