California officials collect more than 1,000 dead birds following outbreak of contagious, bacterial disease

Posted by in category: biotech/medical

More than 1,000 birds died at a lake in Southern California earlier this month, state wildlife officials announced Tuesday.

The birds – primarily migratory water fowls such as Ruddy Ducks, Northern Shovelers, Black-necked Stilts and Gulls – died at the Salton Sea after contracting a contagious bacterial disease known as avian cholera, which is caused by the bacterium Pasteurella multocida, the California Department of Fish & Wildlife (CDFW) said in a statement.

It’s the End of the Gene As We Know It

Posted by in categories: biotech/medical, genetics

We’ve all seen the stark headlines: “Being Rich and Successful Is in Your DNA” (Guardian, July 12); “A New Genetic Test Could Help Determine Children’s Success” (Newsweek, July 10); “Our Fortunetelling Genes” make us (Wall Street Journal, Nov. 16); and so on.

The problem is, many of these headlines are not discussing real genes at all, but a crude statistical model of them, involving dozens of unlikely assumptions. Now, slowly but surely, that whole conceptual model of the gene is being challenged.

We have reached peak gene, and passed it.

In surprising reversal, scientists find a cellular process that stops cancer before it starts

Posted by in categories: biotech/medical, life extension

Just as plastic tips protect the ends of shoelaces and keep them from fraying when we tie them, molecular tips called telomeres protect the ends of chromosomes and keep them from fusing when cells continually divide and duplicate their DNA. But while losing the plastic tips may lead to messy laces, telomere loss may lead to cancer.

Salk Institute scientists studying the relationship of telomeres to cancer made a surprising discovery: a cellular recycling process called autophagy—generally thought of as a —actually promotes the death of cells, thereby preventing cancer initiation.

The work, which appeared in the journal Nature on January 23, 2019, reveals autophagy to be a completely novel tumor-suppressing pathway and suggests that treatments to block the process in an effort to curb cancer may unintentionally promote it very early on.

Common Food Additives May Promote Anxiety-Related Behavior In Mice

Posted by in categories: biotech/medical, food, neuroscience, sex

Food additives known as dietary emulsifiers, commonly found in processed foods to improve texture and extend shelf life, may adversely affect anxiety-related and social behaviors in mice, Georgia State researchers have found.

The scientists also observed sex differences in the mice’s behavioral patterns, suggesting that emulsifiers affect the brain via distinct mechanisms in males and females.

The study, published in Scientific Reports, was led by Geert de Vries, professor of neuroscience and associate vice president for research at Georgia State, and Benoit Chassaing, assistant professor of neuroscience. Andrew T. Gewirtz, professor in the Institute for Biomedical Sciences, also contributed.

Yet another blood pressure medication has been recalled over cancer-causing impurity

Posted by in category: biotech/medical

Last year, the FDA announced a whole bunch of recalls related to blood pressure medication over fears that an impurity created during the manufacturing process could lead to cancer. The compound in question was found in dozens of prescription medications that contained the active ingredient valsartan, prompting several distributors and manufacturers to issue voluntary recalls affecting countless heart patients.

Now, additional medications containing a similar blood pressure drug, irbesartan, have been found to contain the same impurity, and a new round of recalls is upon us. Solco Healthcare LLC is now asking anyone with potentially contaminated medication to stop taking the drug.

Large meta-study reveals aspirin bleeding risks outweigh heart benefits

Posted by in category: biotech/medical

A large meta-study from a team of UK researchers has examined data from over a dozen different clinical trials to conclude that the dangers of daily aspirin use may outweigh any potential benefits for individuals that are generally healthy.

Chinese scientist who gene-edited babies fired

Posted by in categories: bioengineering, biotech/medical, ethics, genetics

A Chinese scientist who created what he said were the world’s first “gene-edited” babies evaded oversight and broke ethical boundaries in a quest for fame and fortune, state media said on Monday, as his former university said he had been fired.

He Jiankui said in November that he used a gene-editing technology known as CRISPR-Cas9 to alter the embryonic genes of twin girls born that month, sparking an international outcry about the ethics and safety of such research.

Hundreds of Chinese and international scientists condemned He and said any application of gene editing on human embryos for reproductive purposes was unethical.
