New research finally explains why. Scientists discovered that these T cells aren’t all the same: one subtype actually helps keep tumors in check, while another shields cancer from immune attack. The balance between these “good” and “bad” cells can determine whether a tumor grows or shrinks. Fri, 06 Feb 2026 11:03:34 EST https://www.sciencedaily.com/releases/2026/02/260206012229.htm https://www.sciencedaily.com/releases/2026/01/260129080432.htm Researchers have discovered how pancreatic cancer reprograms its surroundings to spread quickly and stealthily. By using a protein called periostin, the tumor remodels nearby tissue and invades nerves, which helps cancer cells travel and form metastases. This process also creates a tough, fibrous barrier that makes treatments less effective. Targeting periostin could help stop this invasion before it starts. Fri, 30 Jan 2026 07:44:14 EST https://www.sciencedaily.com/releases/2026/01/260129080432.htm https://www.sciencedaily.com/releases/2026/01/260128075332.htm Scientists at Mount Sinai have unveiled a bold new way to fight metastatic cancer by turning the tumor’s own defenses against it. Instead of attacking cancer cells head-on, the experimental immunotherapy targets macrophages—immune cells that tumors hijack to shield themselves from attack. By eliminating or reprogramming these “bodyguards,” the treatment cracks open the tumor’s protective barrier and allows the immune system to flood in and destroy the cancer.

Researchers found that inflammation in the brain disrupts the energy supply of vital movement-controlling neurons. As their mitochondria fail, these cells weaken and eventually die, worsening motor problems over time. Protecting brain energy systems could open the door to slowing these symptoms. Tue, 06 Jan 2026 03:18:40 EST https://www.sciencedaily.com/releases/2026/01/260106001913.htm https://www.sciencedaily.com/releases/2025/12/251228020016.htm Researchers discovered that clogged brain “drains” show up early in people at risk of Alzheimer’s disease. These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some cases, they may signal Alzheimer’s earlier than other commonly used brain markers. This could help physicians detect the disease earlier, before irreversible damage sets in.

Unlike traditional vaccines designed to target specific tumor proteins, this approach simply revs up the immune system as if it were fighting a virus. The results were dramatic—when paired with checkpoint inhibitors, tumors shrank, and in some cases, the vaccine alone wiped them out. Tue, 19 Aug 2025 02:22:25 EDT https://www.sciencedaily.com/releases/2025/08/250818102951.htm https://www.sciencedaily.com/releases/2025/08/250816113522.htm Scientists have engineered a groundbreaking cancer treatment that uses bacteria to smuggle viruses directly into tumors, bypassing the immune system and delivering a powerful one-two punch against cancer cells. The bacteria act like Trojan horses, carrying viral payloads to cancer’s core, where the virus can spread and destroy malignant cells. Built-in safety features ensure the virus can’t multiply outside the tumor, offering a promising pathway for safe, targeted therapy.

Researchers discovered that combining radiation with immunotherapy can transform stubborn, unresponsive lung tumors into targets for immune attack—especially those considered “cold” and typically resistant. This happens through a rare and poorly understood effect where immune cells are activated systemically, not just at the radiation site. Patients whose tumors underwent this “warm-up” had significantly better outcomes, revealing a promising new strategy for fighting hard-to-treat cancers.

Researchers focused on a group of interacting genes called the Hippo pathway, which serve as a 'stop growing' signal that the lab has shown to inhibit cell proliferation in the ear during embryonic development. The scientists demonstrated that the Hippo pathway also suppresses the regeneration of damaged sensory receptors in the ear and eye of adult mice.

A new study examined records of Campylobacter jejuni infections from 10 states, plotting regional, age-related, and drug-resistance trends from 2013 to 2019. The study found that drug-resistant C. jejuni infections were highest in the 20-39 age group and that quinolone-resistant C. jejuni infections increased from 2013-2019. The researchers also identified regional differences in C. jejuni resistance to quinolones and six other classes of antibiotics.
