Having more children could slow aging

In the journal PLOS One, researchers reveal that women who had more children had longer telomeres than women who had fewer children.

Telomeres are caps at the end of each DNA strand that protect our chromosomes - thread-like structures that contain all our genetic information - from damage.

Each time a cell replicates, telomeres become shorter. They eventually become so short that they stop protecting chromosomes, leaving them vulnerable to damage, which in turn causes our cells to age and stop functioning effectively.

Previously, animal studies have supported the "life history theory," suggesting that higher reproductive behavior is associated with accelerated biological aging.

However, this latest study, led by Prof. Pablo Nepomnaschy and Cindy Barha - both of Simon Fraser University in Canada - contradicts this theory.

    WASHINGTON, Feb 9(Reuters) - Washington must commit more diplomatic and
    security resources to the Indo-Pacific to push back against China as Beijing seeks to create a regional sphere of influence and become the world's most influential power,
    U.S.

    Senate Democrats said on Thursday.

    The majority Democratic staff of the Senate
    Foreign Relations Committee issued the report - seen by Reuters before
    its release - almost exactly a year after President Joe Biden's administration released its strategy to modernize alliances
    in the region, strengthen emerging partnerships
    and invest in relationships.

    The committee's chairman, Senator Robert Menendez, is expected to discuss the report at a hearing on Thursday where senior
    diplomat Wendy Sherman will testify on China policy.


    The Senate report says that vision is "commendable," but gives
    recommendations as to how the U.S.

    government should sharpen the aims of the strategy and
    do more to ensure there are enough resources available to back up its efforts.


    "Despite four successive administrations identifying Asia as a priority region for U.S. attention and assistance, none have made the necessary tradeoffs to ensure that sources are allocated in a manner commensurate with such prioritization," the report said.


    For example, the administration's foreign assistance request for the region for the fiscal year ending in September 2023 was $1.7 billion,
    or only 7.7% of the overall foreign assistance budget, even though the Indo-Pacific region accounts for more than half of the world's population, the report
    said.

    The United States is trying to reassert itself in the region after a period of uncertainty about its
    commitment to Asia under then-U.S.

    President Donald Trump, and concerted efforts by rival China
    to boost its own influence.

    The report said the Biden administration must significantly increase funding for diplomacy and development across the U.S.
    government and dedicate a larger portion of the Department of State operating budget and foreign assistance
    to the Indo-Pacific.

    Its recommendations include working closely with Congress, including providing
    a detailed list of its plans for implementing the Indo-Pacific Strategy and advancing economic integration with countries in the
    region, including prioritizing a meaningful trade program with Taiwan.

    A desire for a hard line in dealings with Beijing
    is one of the few truly bipartisan sentiments in the deeply
    divided U.S.

    Congress, with both Republicans and Biden's Democrats calling for increased
    efforts to counteract China's global influence.



    Tensions between the two countries have been especially high of late, most recently as the United States shot
    down a Chinese spy balloon on Saturday for spying over U.S.

    territory.

    The appearance of the Chinese balloon last week caused political outrage in Washington and prompted Secretary of
    State Antony Blinken to cancel a trip to Beijing that both countries had hoped
    would patch their frayed relations.

    Blinken would have arrived in Beijing on Sunday.

    With havin so much written content do you ever run into any issues of plagorism or copyright infringement?
    My site has a lot of unique content I've either authored myself or outsourced but it appears a lot of it is popping it up
    all over the internet without my authorization. Do you
    know any techniques to help stop content from
    being ripped off? I'd genuinely appreciate it.

    Write more, thats all I have to say. Literally, it seems as
    though you relied on the video to make your point. You obviously know what youre talking about, why
    waste your intelligence on just posting videos to your site when you could be giving us something
    enlightening to read?

    extremely long) so I guess I'll just sum it up what I submitted and say, I'm thoroughly enjoying your
    blog. I as well am an aspiring blog blogger but I'm still new to the whole thing.

    Do you have any points for newbie blog writers?
    I'd certainly appreciate it.
