U.S. markets took a hit as concerns over newly elected Democrats added to fears about AI. Mississippi voters nervously await the result of nail-biter Senate race. And scientists believe they\u2019re on the brink of a new era in Alzheimer\u2019s prevention.
Here\u2019s what to know today.
The Nasdaq and S&P 500 suffered their worst single-day losses since April 2025, when President Donald Trump\u2019s global tariffs sent markets tumbling, with both indexes losing trillions of dollars in value. The tech-heavy Nasdaq plunged 6.3% yesterday, shedding $2.3 trillion in market value, while the S&P 500 fell 4.4%, losing $2.8 trillion. Asian markets also plunged<\/strong><\/a> after they opened Thursday night.

Two lackluster earnings reports on Wednesday night from major chipmakers, Qualcomm and Arm Holdings, triggered the sell-off.
The plunge is partially tied to a blue wave of victories by anti-AI candidates in Tuesday\u2019s midterm elections. Democrats elected to governorships, attorneys general posts and Congress have pledged to slow or halt AI data center construction.
Tech stocks have surged in recent years as excitement about AI has fueled billions of dollars in investments, but questions about whether it will generate returns on those investments have grown louder in recent months.
Trump blamed Democrats for the market slump in a Truth Social post. But, he has said little about Republicans\u2019 election losses since Tuesday, instead signing a proclamation <\/strong><\/a>yesterday designating the Oval Office and Cabinet Room as a national monument.
Some economists aren\u2019t worried about the stock market dip. Letting some air out of the AI bubble now, they say, could reduce the risk of a full-blown crash<\/strong><\/a> later.

The Mississippi Senate race between Democrat Scott Colom and Republican incumbent Cindy Hyde-Smith remained too close to call<\/strong><\/a> as of yesterday afternoon. Colom held a lead of just over 1,700 votes, with only 3,600 ballots left to be counted.
If Colom wins, he would not only join the ranks of Democrats who flipped long-red Senate seats, but he\u2019d also become Mississippi\u2019s first Black senator since Reconstruction.
From the grounds of Jackson State University to the halls of the Masonic Lodge which houses the Mississippi State Conference of the NAACP, voters feel that the state may soon reach a turning point. \u201cHopefully, it\u2019s a sign of a new day, and hopefully people in Mississippi will start looking at policies and issues rather than skin color in deciding who will be their leaders and representatives,\u201d said 75-year-old Carroll Rhodes. NBC News\u2019 Bracey Harris reports from Jackson about the mood in Mississippi.<\/strong><\/a>
Colom, however, said he feels like Democrats gave up on voters in Mississippi before the elections were even underway. \u201cSomehow we got in this cycle where they were like, \u2018Well, we can\u2019t win, so we\u2019re not going to try,\u201d he said in an interview with NBC News. \u201cFirst of all, that\u2019s moral \u2014 that\u2019s a shame, right?\u201d he said, pointing out that Mississippians have been afflicted by healthcare cuts, tariffs and threats to voting rights.

A federal judge blocked construction of President Donald Trump\u2019s proposed \u201cTriumphal Arch\u201d hours after a planning commission dominated by Trump appointees approved the project. U.S. District Judge Tanya Chutkan granted a temporary restraining order sought by the District of Columbia and Virginia, barring the administration from taking any steps toward the project for 14 days. The Trump administration had said it expected construction to begin immediately.
The National Capital Planning Commission approved the controversial arch in an 8-4 vote, with all four opposing votes cast by commissioners not appointed by Trump. The decision followed more than nine hours of public comments, most of which raised concerns about the arch\u2019s impact on Arlington National Cemetery, as well as its height, scale and safety.
Why some lawmakers, veterans and others are opposed to the arch.<\/strong><\/a>
Alzheimer\u2019s disease has historically been difficult to detect and even harder to treat. But the past decade has brought remarkable progress, including blood tests that can identify proteins associated with the disease and treatments that help clear them from the brain. Now, scientists believe they\u2019re on the cusp of the next frontier: preventing Alzheimer\u2019s altogether.
To shed light on these advancements, our NBC News colleague Sue Kroll opened up about her journey getting tested and treated<\/strong><\/a> for early signs of Alzheimer\u2019s in her 50s. After her mother was diagnosed with the disease, Sue noticed that she was struggling to find words or speak in front of groups. A blood test, followed by a brain scan, confirmed the presence of sticky plaques in her brain that are a hallmark of Alzheimer\u2019s.
Sue\u2019s situation is unique, since most Alzheimer\u2019s cases are detected late in life when symptoms are more pronounced. And doctors generally don\u2019t recommend blood tests for people without symptoms, even if they have a family history. To Sue, however, her journey represents a vision for the future: Patients would be screened for Alzheimer\u2019s in their 40s and 50s, then manage their disease through a combination of drugs and lifestyle interventions. Doctors think that scenario could become a reality in the next 10 years. \u2014 <\/em>Aria Bendix<\/strong><\/em>, health reporter<\/em>
Zombie skin<\/strong><\/a> may sound like another TikTok beauty gimmick (or your next Halloween costume), but it\u2019s a real thing that could be impacting your complexion. Plus, can you really erase dark circles? Here\u2019s the truth<\/strong><\/a>, according to dermatologists.
