Here's why "two-dad" babies aren't yet a biological reality

New Scientist

Healthy mice have been created using sperm and cells that aren't quite eggs for the first time. New Scientist questions whether this really brings us any closer to making babies with two biological fathers. Toro Suzuki at the University of Bath, UK and his team combined sperm with non-egg cells to produce 30 mouse pups that then went on to have healthy offspring themselves. But there are a few caveats. To do this, they created 104 embryos, only 30 of which survived.

Baby fat pill could be key to weight loss without going to the gym

Daily Mail - Science & tech

Researchers are one step closer to developing a weight loss pill that replicates the calorie-burning effects of the gym. A study from the University of California at Berkeley found that activating baby fat - the'brown' fat cells that help newborn babies regulate their body temperature - could help adults burn more calories. Unlike white fat cells that are just for storing excess energy, brown fat cells operate similarly to muscle cells and can turn fat and sugars into heat. Researchers are working on a weight loss solution based on the'brown' fat cells that babies use to regulate body temperature by burning calories for heat More than 70 percent of Americans over 20 are overweight and nearly 40 percent are obese. As the obesity epidemic grows, scientists are working on long-term solutions for weight loss.

Humans are biologically wired to categorise colours

Humans are biologically wired to categorise colours in certain ways, new research has found. The study indicates that babies aged between four and six months consistently divide colours up into red, blue, green, yellow and purple. But the research is controversial, as others claim that culture, specifically language, is the key driving factor to how we group colours. Humans are genetically wired to categorise colours in certain ways, new research has found. Humans see colour using the light-sensitive cone cells in their eyes, which can sense either long, short or medium wavelengths of light.

Robot implant is created to treat baby eating defect

Scientists have created a robot that is implanted into the body to treat a rare birth defect which prevents food reaching a baby's stomach.

Of mice and men: Scientists produce babies from same-sex mice pairs

The Japan Times

A team of researchers has produced viable offspring from same-sex pairs of mice, using a novel technology that involves stem cells altered to remove certain genes. While the applications of the research are largely theoretical for now, they could include improving existing cloning methods for mammals and even eventually fertility treatments for same-sex couples. The study, published Thursday in Cell Stem Cell journal, is the first time the method has been successfully implemented, though previous research has looked at other ways to produce babies from same-sex pairs. But while the team was able to produce viable babies from female pairs of mice, whose offspring went on to have their own progeny, the mice produced from male pairs fared less well. They survived only 48 hours after birth, despite a complicated process of gene manipulation intended to eliminate abnormalities resulting from the same-sex reproductive process.
