Breastmilk microbiome linked to method of feeding

Posted by in category: biological

The idea that breastmilk has a microbiome (or microbiota)—a community of bacteria living within it—is relatively new and has sparked debate about where breastmilk bacteria come from. Some scientists believe breastmilk bacteria originate in the mother’s gut while others believe they are transferred to the mother from the infant’s mouth during breastfeeding.

New research from the CHILD Cohort Study—an ongoing birth cohort study involving thousands of Canadian children and their families—has shed some light on this question by highlighting the importance of the infant’s mouth as a source of breastmilk bacteria.

The study, published today in Cell Host & Microbe, found that among the many factors examined, the method of breastfeeding—whether mothers fed their infants directly at the breast or fed them pumped breastmilk from a bottle—was the most consistent factor associated with the milk microbiota composition.

Ending Age-Related Diseases Conference: February Update

Posted by in categories: biotech/medical, business, life extension

July 2019 will see the launch of our second Ending Age-Related Diseases conference at the Frederick P. Rose Auditorium, Cooper Union in New York City. The event was so popular last year that we decided to expand it to two full days of science and biotech business this year.

We will be bringing you the latest aging research, investment, and business knowledge from some of the top experts in the industry. We will be packing two days full of talks from and discussion panels with the people who are developing the technologies that could change the way we regard and treat aging forever.

With just over a month left to grab a lower-cost early bird ticket for the event, we thought that it would be a good opportunity to take a look at what we have in store. We have already announced lots of inspiring speakers from the research and business sectors of the industry, and here are just a few of them.

We need better laws to protect the rights of future frozen cryonicists

Posted by in categories: cryonics, law, life extension

Here’s an important story I wrote on #cryonics for Quartz about a recent tragedy of a young girl and society’s reluctance to give people rights after death. I think something like “Danielle’s Law” could be important moving forward:


Cryogenics is facing legal hurdles for people who want their bodies to be frozen for the future.

Video: Glitter-sized ‘metalenses’ may soon power your smartphone camera

Posted by in categories: computing, mobile phones

Glass lenses, used in everything from smartphone cameras to microscopes, are bulky, heavy, and expensive. Now, a team of U.S. researchers has created high-power lenses from thin, flat arrays of nanosized towers of titanium dioxide that are thinner than a sheet of paper. The novel lenses are made from so-called metamaterials, engineered to control the way in which light waves interact (above). In this case, they are able to focus light across the visible spectrum. The setup allows them to magnify images up to 170 times with high resolution, as good as conventional state-of-the-art optics, the researchers report today in. The new lenses also have the potential to be fabricated—at much lower cost—with standard computer chip–making techniques. As a result, devices such as phones, tablets, and microscopes may soon be built with smaller, and cheaper, metalenses.

MIT says proton’s core generates pressure higher than inside a neutron star

Posted by in category: physics

Physicists at MIT have for the first time calculated the pressure distribution inside a proton. One incredible finding by the researchers is that the core of a proton generates pressures greater than what’s found inside a neutron star. That discovery is so incredible because a neutron star is among the densest known objects in the universe.

Hachimoji DNA doubles the genetic code

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

Researchers in the US have built an “alien” DNA system from eight building block letters, so expanding the genetic code from four and doubling its information density. The new system meets all of the requirements for Darwinian evolution and can also be transcribed to RNA. It will be important for future synthetic biology applications and expands the scope of molecular structures that might be capable of supporting life, both here on Earth and more widely in the universe.

One of the main characteristics of life is that it can store and pass on genetic information. In modern-day organisms, this is done by DNA using just four building blocks: guanine, cytosine, adenine and thymine (G, A, C and T). Pairs of DNA strands form a double helix with A bonding to T and C bonding to G.

Four more building blocks .

Hawaii’s False Missile Alert Shows Americans Have No Idea What to Do in Nuclear Attack

Posted by in categories: existential risks, military

Many people in Hawaii faced that very question on Jan. 13, 2018. That morning, at 8:07 a.m. local time, the Hawaii Emergency Management Agency sent out an alert advising residents to seek shelter from an incoming ballistic missile.

Unbeknownst to just about everyone at the time, however, the alert was a false alarm. Even the operator who sent out the alarm, issued over text messages and on TV and radio stations, thought it was real. But it was accidentally sent out during a shift change, and the incoming operator didn’t realize that the alert was part of a preparedness drill.


An erroneous alert about a nuclear attack was sent to Hawaii residents. The ensuing confusion and hysteria revealed that Americans are not prepared.
