A child's educational success depends on the genes that they haven't inherited from their parents, as well as the genes they have, according to a new study led by UCL researchers.
Researchers make a breakthrough in understanding the genesis of uterine leiomyomas
Scientists at the University of Helsinki and Helsinki University Hospital have made a breakthrough in understanding the genesis of uterine leiomyomas, also called fibroids.
Fibroids are extremely common tumors. They are a major burden for women s health worldwide, and the most common cause of hysterectomy. The Finland Myoma Study published in
Nature found that the part of the human genome that controls expression of genes, is of major importance in fibroid development.
The findings of the new study represent a significant advance in fibroids research. Without detailed knowledge on the mechanisms of tumorigenesis involved, it would be difficult to develop targeted therapies for this condition affecting hundreds of millions of women.

Researchers have found evidence that a coronavirus epidemic swept east Asia some 20,000 years ago and was devastating enough to leave an evolutionary imprint on the DNA of people alive today.
The new study suggests that an ancient coronavirus plagued the region for many years, researchers say. The finding could have dire implications for the Covid pandemic if it s not brought under control soon through vaccination. It should make us worry, said David Enard, an evolutionary biologist at the University of Arizona who led the study, which was published on Thursday in Current Biology. Until now, researchers could not look back very far into the history of this family of pathogens.

Los seres humanos a veces pensamos en nosotros mismos como algo muy especial: aunque somos animales, somos los únicos que desarrollamos una civilización.
Si a eso le sumamos que nuestra especie es la única que actualmente existe en el género
Homo, pues tendríamos más razones para sentirnos únicos.
Esto no siempre fue así: incluso algunas de esas especies, como los neandertales, ahora extintos, compartieron el tiempo y el territorio con algunos de nuestros ancestros.
Incluso el
Homo sapiens: también tenemos evidencias de que los
denisovanos u homínidos de Denisova, coexistieron con los humanos arcaicos.
