A group of scientists, patient advocates and bioethicists are pushing for Washington to lift the ban on mitochondrial replacement therapy, a procedure that combines genetic material from a mother, father and female donor, Stat News reports.

The big picture: Advocates for the procedure say it helps women who carry genetic diseases have healthy children that are biologically related to them. Opponents cite safety, ethical and religious concerns.

What's new: Last week, a Greek woman had the first successful birth in a clinical trial of the treatment.

Where it stands: Congress passed an amendment in 2015 that effectively banned the procedure in the U.S., and it's been renewed every year since.

  • Congress could either change the amendment, which is voted on every year, or the Food and Drug Administration could change its interpretation of it.

How it works: The point, at least for supporters in the U.S., is to help babies avoid mitochondrial diseases, which are inherited through the mother's DNA. Other countries have used it as a response to infertility.

  • Mitochondrial therapy involves taking the nucleus of the mother's egg and placing it into a donor egg that has healthy mitochondria and has had its nucleus removed.
  • The egg is fertilized with sperm before or after this, and then the rest of the in vitro fertilization process is standard.
  • The baby then ends up with DNA from all three people involved, although only with a tiny amount from the donor.

Capitol review panel recommends more police, mobile fencing

A panel appointed by Congress to review security measures at the Capitol is recommending several changes, including mobile fencing and a bigger Capitol police force, to safeguard the area after a riotous mob breached the building on Jan 6.

Why it matters: Law enforcement officials have warned there could be new plots to attack the area and target lawmakers, including during a speech President Biden is expected to give to a joint session of Congress.

Financial fallout from the Texas deep freeze

Texas has thawed out after an Arctic freeze last month threw the state into a power crisis. But the financial turmoil from power grid shock is just starting to take shape.

Why it matters: In total, electricity companies are billions of dollars short on the post-storm payments they now owe to the state's grid operator. There's no clear path for how they will pay — something being watched closely across the country as extreme weather events become more common.

U.S. Chamber decides against political ban for Capitol insurrection

The U.S. Chamber of Commerce revealed Friday it won't withhold political donations from lawmakers who simply voted against certifying the presidential election results and instead decide on a case-by-case basis.

Why it matters: The Chamber is the marquee entity representing businesses and their interests in Washington. Its memo, obtained exclusively by Axios, could set the tone for businesses debating how to handle their candidate and PAC spending following the Jan. 6 Capitol attack.
