Breakthrough Immunotherapy Eradicates Cancer in 84 Patients

USUnited States|

A groundbreaking immunotherapy, termed immunoablative therapy, has shown remarkable success, with 84 out of 100 participants experiencing complete cancer remission. This treatment focuses on patients with a specific genetic mutation, called mismatch repair deficiency, which enhances their response to the therapy using a humanized mouse antibody known as dostarlimab. According to the research published in the New England Journal of Medicine, 80% of participants, who had cancer types such as esophageal, stomach, colon, liver, bladder, uterus, and prostate cancers, saw their tumors vanish.

Patients like 71-year-old Maureen Sideris, who was diagnosed with gastroesophageal cancer, report feeling rejuvenated post-treatment. Sideris remarked, “The cancer has disappeared in my PET images and biopsies,” while oncologist Luis Alberto Díaz emphasized the therapy’s potential to spare patients from more aggressive treatments like chemotherapy and surgery. The therapy costs approximately $55,000 per patient, but Díaz notes it can ultimately reduce overall healthcare costs. Researchers stress that long-term benefits are still being evaluated, particularly for non-rectal cancer cases.

Cybercriminals Leverage Infostealer Malware to Harvest 1.7 Billion Credentials

A staggering 1.7 billion passwords were leaked on the dark web in 2024, according to cybersecurity researchers at Fortinet. This surge reflects an alarming 500% increase in infostealer malware activity over the past year, targeting individual devices rather than centralized databases. Infostealers, programs specifically designed to extract sensitive information like usernames, passwords, and session tokens, operate through active infections on users' machines. Once installed, they can scan for credentials stored in browsers and digital wallets. The resulting data is often sold by initial access brokers to other cybercriminals, enabling widespread exploitation, including attacks on personal bank accounts and corporate networks. Fortinet's 2025 Global Threat Landscape Report highlighted several rampant infostealers, including RedLine, Vidar, and Raccoon. Users are urged to adopt a mix of strong security habits, such as using password managers, enabling two-factor authentication, and maintaining updated security software to mitigate risks associated with this growing threat. Experts suggest that maintaining vigilance against phishing attempts and avoiding dubious downloads are essential steps to protect personal information from cybercriminals.

NASA Captures Spectacular Image of Black Hole Devouring Star 600 Million Light-Years Away

NASA has unveiled a breathtaking image of a black hole consuming a star in an event known as a Tidal Disruption Event (TDE), which occurred 600 million light-years from Earth. The image was captured by the Hubble Space Telescope and features a bright dot representing the burst of radiation emitted during the star's destruction. According to NASA's post on X, "A black hole revealed itself from 600 million light-years away when it ripped apart and swallowed a star." Yuhan Yao, a lead study author at the University of California, Berkeley, stated that this is the first offset TDE identified by optical sky surveys, hinting at the potential for discovering wandering black holes in the future. TDEs occur when a star strays too close to a black hole, resulting in its debris being stretched and heated, producing intense bursts of energy. Ryan Chornock, an associate adjunct professor at UC Berkeley, emphasized that these events are crucial for detecting massive black holes that are otherwise difficult to observe.

Bill Gates Accuses Elon Musk of Endangering Global Health

In a recent interview with the Financial Times, Microsoft founder Bill Gates accused billionaire Elon Musk of jeopardizing global health by cutting funding to the U.S. Agency for International Development (USAID). Gates stated that these funding cuts threaten to revive diseases like measles, HIV, and polio. "The picture of the world's richest man killing the world's poorest children is not a pretty one," Gates remarked, urging Musk to witness the effects of such financial decisions firsthand. Gates also announced his commitment to give away 99% of his wealth through the Bill & Melinda Gates Foundation, with a pledge of an additional $200 billion over the next two decades. The foundation has already donated over $100 billion to combat global health and poverty issues. According to his blog, Gates stated the foundation plans to cease operations by December 31, 2045, emphasizing, "There are too many urgent problems to solve for me to hold onto resources." With a personal fortune of $168 billion, Gates remains one of the wealthiest individuals globally and aims to address significant societal challenges through his philanthropic efforts.
