Cancer may offer a certain degree of protection against alzheimer’s disease thanks too a protein produced by tumor cells that appears to contribute to the breakdown of protein plaques associated with this type of dementia.This is the main conclusion of research led by the Huazhong University of Science and Technology (HUST),which provides new clues about a relationship that has generated speculation for decades within the scientific community.
In 2012, after analyzing and tracking the clinical details of nearly 1,300 patients over the age of 65 for a decade, a study observed that cancer survivors had a 33% lower risk of developing cognitive impairment compared to people with no history of cancer. The finding drew attention for suggesting a possible inverse association between the two diseases, traditionally considered unrelated to each other.
However, the results were received with caution. Several specialists warned that they may be influenced by the so-called survival bias: it is possible that many people with cancer do not live long enough to develop or manifest the first signs

The legal battle surrounding a potential ban of TikTok in the United States continues, with recent developments focusing on data security concerns and ongoing appeals.As of January 26, 2026, a nationwide ban is not in effect, but the situation remains fluid following court rulings and legislative actions.
TikTok and National Security Concerns
Table of Contents
The U.S. government maintains that TikTok, owned by ByteDance, poses a national security risk due to concerns that user data could be accessed by the Chinese government. This concern stems from China’s National Intelligence Law, which compels organizations to support and cooperate with state intelligence work.
In April 2024, President Biden signed into law H.R.7535 – Protecting Americans from foreign Adversary controlled Applications Act, giving ByteDance nine months to divest its ownership stake in TikTok or face a ban in the United States. ByteDance has challenged this law in court.
Example: The Justice Department filed a motion in November 2024 to dismiss TikTok’s lawsuit challenging the law, arguing the legislation is a legitimate exercise of national security authority. Justice Department Press Release
Committee on Foreign Investment in the United States (CFIUS) Review
The committee on Foreign Investment in the united States (CFIUS) has been reviewing TikTok’s operations since 2020, seeking to mitigate potential security risks. CFIUS has the authority to recommend actions to the President, including divestment orders.
Detail: CFIUS’s concerns center on the potential for the Chinese government to access the data of 170 million monthly active U.S. users, including location data, browsing history, and biometric identifiers.The proposed Project Texas, a plan by ByteDance to store U.S. user data on servers located in the United States and managed by Oracle, was initially seen as a potential solution, but has been deemed insufficient by U.S.officials.
Example: In February 2025, CFIUS formally rejected ByteDance’s revised project Texas proposal, citing ongoing concerns about data access and control. Reuters Report on CFIUS Rejection
Legal Challenges and Court rulings
TikTok has filed multiple lawsuits challenging the federal government’s actions, arguing that the law violates the First Amendment rights of its users. These cases have progressed through the court system.
Detail: In December 2025, the U.S. Court of Appeals for the District of Columbia Circuit heard oral arguments in TikTok’s challenge to the law. The court is expected to issue a ruling in February 2026. tiktok argues the ban is a violation of free speech, while the government maintains it is a necessary measure to protect national security.
Example: The D.C.Circuit Court case is TikTok, Inc. v. United States, case number 24-5081. Case Details on the D.C. Circuit Website
Federal Communications Commission (FCC) Involvement
The Federal Communications Commission (FCC) has also been involved in the debate, with Commissioner Brendan Carr advocating for a ban on TikTok and other apps deemed to pose a national security risk.
Detail: In March 2025, Commissioner Carr called for a ban on TikTok, citing concerns about data security and potential Chinese government influence. He also urged Apple and Google to remove TikTok from their app stores.
