The human heart is an organ whose cells rarely divide, making tissue repair and regeneration a huge problem following a heart attack. Many animals, such as zebrafish and salamanders, are different; they can regenerate damaged hearts easily.

As humans, we also once had the same regenerative capacity during our early development, but after we were born, we lost this ability. This is also true for many other organs, including the brain, spinal cord, and pancreas. The cells in these tissues divide very rarely if at all, and this is a big problem. But, what if we could get that regenerative ability back and repair damage to our hearts the way these amazing animals do?

Researchers have been trying for decades to find out how we can enjoy the same tissue regeneration, but they have met with limited success—until now.

However, the pattern seems clear, and is worth heeding by other nations: despite China’s reputation for authoritarian and hierarchical rule, in science the approach seems to be to ensure that top researchers are well supported with funding and resources, and then to leave them to get on with it.

Chinese investment is paying off with serious advances in biotech, computing and space. Are they edging ahead of the west?

Imagine constantly worrying that something you eat is going to cause your throat to swell shut or your heart to stop beating. That’s the reality people with severe peanut allergies must live with every day, because their bodies launch out-of-control immune responses against even a trace of peanut protein.

But now, relief may be on the horizon. A phase 3 clinical trial by pharmaceutical company Aimmune Therapeutics shows that gradual and methodical exposure to purified peanut protein can train the body to drastically tone down the reaction. After one year of daily treatment with the company’s peanut protein-filled capsules, currently called AR101, study participants could safely tolerate 30 times more allergen than they could before the trial began.

The trial included 496 children aged 4 to 17 with allergies so severe that they could not ingest more than 30 milligrams of peanut protein without experiencing moderate to highly dangerous effects. For reference, one peanut contains 250 to 350 milligrams of peanut protein.

According to China’s National Central Cancer Registry, Esophageal cancer is one of the most common forms of cancer in China. Like many other types, cancer of the esophagus can be treated with chemotherapy. But, as is also true of other forms of cancer, chemotherapy isn’t always successful. In China, and around the world, there’s a great need for the development of new treatments.

Dr. Shixiu Wu, president of the Hangzhou Cancer Hospital, has tested a somewhat new treatment that takes a patient’s T-cells from the body, genetically edits them to target cancerous cells, then puts the altered cells back. If the process sounds at all familiar, it’s probably because using T-cells in this manner was approved by the U.S. Food and Drug Administration back in August 2017.

Using artificial intelligence and machine learning techniques, researchers at Shiley Eye Institute at UC San Diego Health and University of California San Diego School of Medicine, with colleagues in China, Germany and Texas, have developed a new computational tool to screen patients with common but blinding retinal diseases, potentially speeding diagnoses and treatment.

Using a state-of-the-art type of electron microscopy, an MIT-led team has discovered the structure of an enzyme that is crucial for maintaining an adequate supply of DNA building blocks in human cells.

Summary: Treatability of cancer was raised to over 80% by a new intelligent system that sifts through massive genetic datasets to pinpoint targets for cancer treatment, say these scientists. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Scientists in Singapore have discovered a significantly improved way to treat cancer by listening to many different computer programs rather than just one.

Their new computer program reaches a consensus on how to treat a specific tumor, and it is significantly more accurate than existing predictive methods. The system isolates the Achilles heel of each individual tumor, helping doctors to choose the best treatment.

Summary: UCSD researchers just reported that a strain of bacteria prevents skin cancer. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

The human microbiome is emerging a major player in protecting our health and researchers at the University of California San Diego (UCSD) just reported that some strains of skin bacteria safeguard against cancer.

Leading the study is Richard Gallo, MD, Ph.D., a Distinguished Professor and the chair of the Department of Dermatology at the UCSD School of Medicine, who says.
