CRISPR bombshell: Chinese scientist claims he has created refurbished twins

In the week to the International Human Resource Summit in Hong Kong, China, Han Jiankui, a Chinese scientist shocked many claiming that his team had used CRISPR-Cas9 to construct DNA from twin baby girls recently born to fight a key receptor on white blood cells to make them HIV resistant. The statement – not yet reported in a scientific paper – met with criticism of criticism, with some researchers and biologists calling the work “premature”, “ethically problematic” and even “monstrous”.

Mars mission was lucky: NASA Lander moves down into a sandy crater, easier study of the interior of the planet

NASA’s InSight spacecraft survived its swinging descent through Mars’s thin atmosphere and landed successfully on the surface of the planet this week. Although InSight did not hit the eye of the bull in its target zone, the land-filled crater, like the ship, provided a good environment for the landlord to use instruments to study the interior of the planet.

“I feel an obligation to be balanced.” Noteed biologist comes to the defense of redacting researcher

This week, only a prominent scientist spoke quickly to defend Han Jiankui, the Chinese research claiming to have created the first redirected children: Geneticist George Church, whose Harvard University lab played a groundbreaking role in to develop CRISPR, the genomedifier used to manipulate embryonic cells in the controversial experiment. Even though the church has reservations about his actions, he also says that the frenzy of criticism about the experiment was extreme.

Watch bump beetles trick thousands of fishes to be dinner

Puck Choice has one of the biggest mouths on the planet – and an appetite to match. The bush size mammals can eat up to 2500 kilos of fish a day and a new study reveals a way that they are linked to these huge numbers: by opening their mouths halfway out of the water, they make small dams that many fish miss out on the place of refuge. Once they have gathered in the mouth of the whales, they squeeze their jaws in a light snack.

Spider mother spotted breastfeeding his offspring with milk

Got milk? Researchers observed jumping spider mites that deposited milk drops around the estate for their offspring to sip on. After a few days, the baby spiders began to stand at the entrance to her mother’s birth canal to suck, and they continued to supplement their diets with milk until they reached sexual maturity. This level of prolonged parental care is almost unheard of in insects or any species beyond large social mammals, such as humans and elephants.
