Scientists have developed a scalable, next-generation platelet bioreactor to generate fully functional human platelets in vitro. 

A new discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees but instead 'dance' in orderly disc-shaped orbits is a challenge to our understanding of how the universe formed and evolved.   

The universe contains billions of galaxies. Some, such as the Milky Way, are immense, containing hundreds of billions of stars. Most galaxies, however, are dwarfs, much smaller and with only a few billion stars.

For decades astronomers have used computer models to predict how these dwarf galaxies should orbit large galaxies. They had always found that they should be scattered randomly.

Too much dietary fat is bad for the heart, everyone knows that by now, but not all fats are equal. The right kind of fat keeps the heart healthy, and a paper in The Journal of Experimental Medicine shows how it works.

Unlike saturated fats discussed in popular media, unsaturated dietary fatty acids, such as eicosapentaenoic acid (EPA), are known to protect against cardiovascular diseases. However, the mechanism and the specific fat metabolites responsible for this protection were unknown. 

A team of researchers made a seminal breakthrough in understanding the molecular basis of fibroadenoma, one of the most common breast tumors diagnosed in women. Led by Professors Teh Bin Tean, Patrick Tan, Tan Puay Hoon and Steve Rozen, the team used advanced DNA sequencing technologies to identify a critical gene called MED12 that was repeatedly disrupted in nearly 60% of fibroadenoma cases. 

A new single-cell technique can help investigate how the environment affects our development and the traits we inherit from our parents. It can be used to map all of the 'epigenetic marks' on the DNA within a single cell,which will boost understanding of embryonic development, enhance clinical applications like cancer therapy and even reduce the number of mice used in research.

"She'll grow out of it," used to be a common phrase about raising kids, meaning it wasn't anything that was wrong physically or in upbringing, it is just the diversity of human existence. Some kids develop later. But in today's hyper-diagnosis culture, researchers have wanted to figure out if that old saying was true, or just wishful thinking.

A  study of 473 sets of twins followed since birth has found that, compared to single-born children, 47 percent of 24-month-old identical twins had language delay compared to 31 percent of non-identical twins. Overall, twins had twice the rate of late language emergence of single-born children. None of the children had disabilities affecting language acquisition.
