Common Vape Flavoring May Disrupt Early Embryo Development, Laboratory Study of Human Stem Cells Suggests

Laboratory experiments found that vanillin, a common vape flavoring, altered the development of human embryonic stem cells.

In 2000, Johns Hopkins team treated 18 paralyzed rodents with neural stem cells. 6 years later, the team engineered working motor-neuron circuits in paralyzed adult animals, extending the original finding

Johns Hopkins research from 2000 and 2006 represents an important scientific progression in the search for ways to repair damaged nervous systems. The original experiment involving 18 paralyzed rodents provided evidence that neural stem cells could migrate toward spinal-cord injury and coincide with functional improvement.

Your Gut Cells Can "Forget" What They Are to Repair Damage, and Colon Tumors Steal the Same Switch

MSK researchers identified ZFP36L2 as the protein that lets gut cells revert to a stem-like state, a repair program that colorectal cancer exploits to spread.

Recurring risk: Like Zika, Oropouche virus can also affect the brains of unborn babies

Discovered in 1955, the Oropouche virus circulated mainly in the Amazon, causing a febrile illness virtually indistinguishable from dengue, Zika, and chikungunya, viruses also transmitted by biting mosquitoes.

Biohacker Bryan Johnson Says He 'Cloned' Himself, but Scientists Say It Misrepresents Stem Cell Science

Biohacker Bryan Johnson says he "cloned" himself using his own cells, but scientists say the technology is actually induced pluripotent stem cells, not human cloning.

Gray Hair Reason Found: A Japanese study explains why people get grey hair and it may be linked to cancer

Why Do People Get Grey Hair: New research in Japan suggests grey hair may signal a body's protective response against Cancer. Stem cells shut down after severe DNA damage, preventing harm, however, certain carcinogens can cause these cells to multiply unchecked. This process can lead to melanoma, the most dangerous…

Biohacker Bryan Johnson Claims He 'Cloned' Himself as a Newborn to Grow Organs After Incurable Disease Diagnosis

Bryan Johnson says his autoimmune gastritis diagnosis inspired him to create a 'newborn' version of himself using stem cells in the hope of growing replacement organs. The controversial experiment has divided opinion online.

Why Indian Hair Goes Prematurely Grey: What Science Says About Melanin and Stress

The melanin problem starts earlier than you thinkA 2016 study published in the International Journal of Trichology, drawing on data from Indian dermatology clinics, defined premature greying as onset before age 25 in Indians, compared to before 30 for Caucasians. That five-year gap is not trivial. It points to a…

Could space-grown stem cells unlock faster cancer treatments and revolutionize organ regeneration breakthroughs? NASA’s ISS experiments are revealing surprising answers about the power of microgravity medicine

Space stem cell research is rapidly changing cancer treatment and regenerative medicine worldwide. Scientists aboard the International Space Station discovered stem cells grow into realistic 3D tissue structures faster in microgravity. NASA says these conditions reveal biological processes hidden by Earth’s gravity. Researchers now study tumour growth, tissue repair, immune…

Stem cells have potent potential for diabetes treatment

Humans have around 30 trillion cells in our adult bodies. Amazingly, each of these cells came from a handful of about 100 stem cells in the earliest days of development. The ability of these embryonic stem cells to turn into any cell type makes them pluripotent — something that researchers…
