    We’re Using Stem Cells to Reverse Baldness and It’s Actually Working

    Some very hairy mice are bringing us another step closer to un-LOCKing a way to regenerate a full head of hair. Did somebody say a pun?! About 50% of men and 25% of women experience at least partial hair loss by the age of 50, whether due to age, medical treatments, or disease. Current options for those looking to reverse this loss include things like medications that may slow hair loss and transplants from hair follicles elsewhere on the body. But neither have the often desired effect of restoring a thick and full volume of hair. Researchers have been optimizing techniques for culturing “hair follicle germs” in a dish for…

    Your Skin Cells Could Make a Baby, Will This Be the End of Infertility?

    We all know where babies come from. An egg is fertilized by sperm and the resulting zygote needs to be implanted in a uterus so it can grow and divide. The key here is the union of the gametes: sperm and egg. This means same-sex partners, or partners who are unable to provide gametes themselves, need to rely on donors. But what if that wasn’t the case? What if we could just generate gametes from the partners? Soon, we might be able to. The method is called in-vitro gametogenesis. It involves converting adult cells into lab-made eggs and sperm cells that can combine to create a zygote. This could pave…

    The James Webb Space Telescope Is Delayed (Again)! What Is Happening?

    The James Webb Space Telescope being developed by NASA is set to be one the most exciting space observatories ever developed!, with totally novel technologies and instruments that will give us new insights into our universe. But unfortunately, its completion and launch has been delayed. Again. What’s goin’ on? The initial completion window for the James Webb Space Telescope, or JWST, was supposed to be between 2007 and 2011. There were some pretty severe budget and schedule issues, resulting in a 2011 overhaul of the project that set a new completion date for October of 2018. That turned out to be a little too optimistic, so they pushed it back…

    Hi everyone, Dr. Ali Mattu here. Recently the awesome people at D News invited me to come over and make some science videos together! On TestTube Plus, Trace Dominguez and I explored how to overcome anxiety. I partnered with D News’s Julia Wilde to explain hair-pulling disorder. And I managed to squeeze in an episode on the psychology of sexting. Let me know what you think of the videos in the comments below and be sure to subscribe to D News for more science videos every day of the week.

    How Powerful is Singapore?

    In 1965 Singapore gained its independence from Malaysia. Since then, the tiny island city-state has been industrializing and growing at an unprecedented rate. This year, they were voted the most expensive city in the world for the second year running. So we wanted to know, how powerful is Singapore? Well, for starters, Singapore is a tiny island in Southeast Asia, with a population of a little over 5 million packed into 277 square miles. That’s roughly if everyone in Minnesota squeezed into an area the size of San Francisco. Along with South Korea, Taiwan, and Hong Kong, Singapore is one of the Four Asian Tigers; nations that have experienced significant…
