Another breastfeeding benefit: Preparing baby’s belly for solid food

The moment of birth marks the beginning of a beautiful, lifelong relationship between a baby and the billions of microbes that will soon colonize his or her gastrointestinal tract.

In a study published today in Frontiers in Cellular and Infection Microbiology,
researchers from the UNC School of Medicine and UNC College of Arts and
Sciences found that a baby’s diet during the first few months of life
has a profound influence on the composition, diversity, and stability of
the gut microbiome. These factors, in turn, influence the baby’s
ability to transition from milk to solid foods and may have long-term
health effects.

“We found that babies who are fed only breast milk have microbial
communities that seem more ready for the introduction of solid foods,”
said Andrea Azcarate-Peril, PhD, assistant professor in the department
of cell biology and physiology and the study’s senior author. “The
transition to solids is much more dramatic for the microbiomes of babies
that are not exclusively breastfed. We think the microbiomes of
non-exclusively breastfed babies could contribute to more stomach aches
and colic.”

MPs vote in favour of ‘three-person embryo’ law

MPs have voted in favour of making Britain the first country in the world to permit IVF babies to be created using biological material from three different people to help prevent serious genetic diseases.

In a historic debate, the House of Commons voted by 382 to 128 – a
majority of 254 – to allow mitochondrial donation through a
controversial amendment to the 2008 Human Fertilisation and Embryology
Act. They approved the regulation in spite of some critics warning it
was a step towards creating “three-parent” designer babies. The regulations will now have to be approved in the House of Lords, where they are likely to be passed.

Mitochondrial diseases are caused by genetic faults in the DNA of tiny structures that provide power for the body’s cells. The DNA is held
separately to the 20,000 genes that influence a person’s identity, such
as their looks and personality. Because mothers alone pass mitochondria
on to children, the diseases are only passed down the maternal line.

The “three parent” IVF therapy, which could help to eliminate certain
incurable genetic diseases, involves swapping a fraction of a mother’s
DNA with that from an anonymous female donor. Around 100 children
each year are affected by genetic defects in the mitochondria and in
around 10 cases the defects cause severe illnesses such as liver
failure, muscle wasting, blindness and brain damage.

1) Two eggs are fertilised with sperm, formulating an bud from a dictated relatives and another from a donors 2) The pronuclei, that
enclose genetic information, are private from both embryos though
usually a parents’ are kept 3) A healthy bud is combined by adding a
parents’ pronuclei to a donor embryo, that is finally ingrained into a
womb

Here’s how much plastic enters the ocean each year

Adding together all 192 countries in the world with a significant coastal population, the researchers report online today in Science that about 4 million to 12 million metric tons of plastic washed offshore in 2010 alone, or about 1.5% to 4.5% of the world’s total plastic production—enough to
cover every foot of coastline on the planet. That’s just the beginning
of the problems, the team says, as scientists still don’t know where more than 99% of ocean plastic debris
ends up—and what impact it’s having on marine life and the human food
supply. What’s more, the authors predict that the annual amount of
plastic waste tumbling out to sea will more than double in the next 10
years.

??? someone broke into my grandmas house while she was gone & shaved the matted fur off her cat

i want to emphasize that the cat was the only thing altered here

would also like to add that this occcurred sometime between 11 pm & 9 am. we have no leads. the cat is fine & probably appreciates not having a huge mat on his neck, but, like, that’s a really weird kind of vigilante justice, still

chaotic good
