Why do we get vaccinated in the shoulder with the Covid-19 vaccine? At this point you are probably asking yourself what’s so special about …

The girl who was born from a cryogenic embryo frozen 28 years ago

A little girl born on October 26, 2020 in the American state of Tennessee entered the history books after she was born from an embryo that underwent a cryogenic process 28 years ago. Molly Everette Gibson’s embryo was cryogenized on October 14, 1992 and was stored in a liquid nitrogen tank until February 2020. This …

C-Section born children have a 33% higher risk of having autism, according to a controversial study. What is the risk of ADHD

C-section born children have a 33% higher risk of having autism disorder and 17% of ADHD, according to a research that combined 61 studies across 19 countries. The statistical analysis, which was recently published in the JAMA Network Open, does not show that caesarean section directly causes such medical problems. Other factors that have led …

The correct age of the Earth’s core

The inner core of the Earth or the nucleus, which is a solid iron ball larger than Pluto, could be younger than previously thought. This is the conclusion of a study published Monday, suggesting that 565 million years ago it had not yet begun its consolidation. Since its existence was discovered, back in 1936, the age of …

NASA warns that a long winter can hit the space. Record temperatures could be recorded

A long winter and record low temperatures could be felt in space, NASA warns. A space agency researcher says the sunspot activity is extremely low, which will record record temperatures in space. However, the Earth’s climate will not be affected. “We are seeing a cooling trend,” said Martin Mlynczak of the Langley Research Center, NASA. He added …

An impressive detail found in a piece of amber that’s 100 million years old

Graphene could give us the electronics of the future much faster

New experiments presented in Nature magazine seem to show that this substance composed of a single layer of carbon atoms can transform electronic signals transmitted in gigahertz into higher frequency signals. We are talking about terahertz, capable of carrying up to 1,000 times more information per second. Electromagnetic waves in the terahertz range are notoriously …

Scientists created the first human esophagus made from stem cells

Bioengineering scientists working to produce the entire human gastrointestinal system in the laboratory reported that pluripotent stem cells were used to create a human esophagus. This is the first time scientists have been able to grow human pluripotent stem cell (PSC) esophageal tissue, cells that theoretically can form any type of body tissue. Published in …
