WASHINGTON (AP) — Most Americans say it would be OK to use gene-editing technology to create babies protected against a variety of diseases — but a new poll shows they’d draw the line at changing DNA so children are born smarter, faster or taller.
A month after startling claims of the births of the world’s first gene-edited babies in China, the poll by The Associated Press-NORC Center for Public Affairs Research finds people are torn between the medical promise of a technology powerful enough to alter human heredity and concerns over whether it will be used ethically.
Jaron Keener, a 31-year-old exhibit designer at Pittsburgh’s Carnegie Museum of Natural History, said he’s opposed to “rich people being able to create designer babies.”

Anxiety disorders are severe mental disorders in which patients suffer from intense fears and anxiety or from sudden, inexplicable panic attacks. In extreme cases, the affected individuals barely leave their homes, which can have serious consequences for their relationships with family and friends as well as for their professional lives. Scientists at the Max Planck Institute for Experimental Medicine in Göttingen have now identified a synaptic protein which, when inactivated, has an anxiolytic effect in mice.
Around 10 percent of the population suffer from anxiety disorders, and current treatment options only offer effective help for a proportion of those affected. One of the changes observed in the brains of patients with anxiety disorders is an increased neuronal activity in the amygdala, a brain region that plays a key role in processing emotions such as anxiety or fear. An overactivation of the amygdala is thought to be involved in causing exaggerated anxiety. Many anxiolytic medications such as benzodiazepines presumably normalize this overactivation by strengthening the function of inhibitory synapses.
Synapses are connections between nerve cells in the brain, at which information is transmitted from one nerve cell to another. At inhibitory synapses, this transmission results in a reduction in the activity of the neighbouring nerve cells. In the amygdala, for instance, this inhibits the transmission of stimuli that trigger fear and anxiety. Benzodiazepines strengthen this inhibitory effect—but unfortunately they affect not only those inhibitory synapses that transmit anxiogenic stimuli but also many other inhibitory synapses in the brain. This can lead to significant side effects such as pronounced sedation and impaired concentration. Accordingly, scientists are searching for new, more specific targets for anxiolytic medications.

The next step for our Forever Healthy Berlin meetup…
We are a community collaborating on how to implement our early stage rejuvenation treatments.
The world has started the transition from an era where we were utterly helpless about our aging process to one where aging is under full medical control, and age-related diseases are a thing of the dark past.
We are not there yet, but the theoretical groundwork has been laid out, and scientists have successfully started working on the fundamentals. The first human rejuvenation therapies are under development and with Senolytics, NAD+ Restoration, Lipid Replacement, Decalcification, mTOR Modulation, Geroprotectors, and others some of those therapies are already available to the early adopters today.

BEIJING, Dec. 28 (Xinhua) — A Chinese research group has identified a gene variant that plays a key role in the development of Alzheimer’s disease in Han Chinese, the largest ethnic group in China.
The study was recently published by the National Science Review, an English journal affiliated with the Chinese Academy of Sciences (CAS).
Alzheimer’s disease (AD) is an irreversible, progressive brain disorder that slowly destroys memory, thinking skills and the ability to carry out simple tasks. The disease affects about 48 million people worldwide, and the number is expected to increase with the aging population. There is no effective cure.

Replication is nature’s greatest magic trick. Watch closely, and before your very eyes you’ll see a single cell blur into two virtually identical copies. Presto.
After more than half a century of research on molecular genetics, it would be easy to assume we’ve had this biological sleight-of-hand all figured out — but it’s not the case.
Now, by applying cutting edge technology, researchers have uncovered crucial details showing how DNA times its own replication.
