DNA damage can originate from internal sources like metabolic by-products or normal cellular activities, as well as external factors such as cosmic radiation, diet, and pollution.

Incyte tops this list due to its rare combination of commercial scale, cash generation, and pipeline depth. The company posted FY2025 revenue of $5.14 billion, up 21.2% YoY, anchored by Jakafi generating $828.2 million in Q4 2025 alone (+7% YoY) and Opzelura delivering $207.3 million (+28% YoY). With $3.58 billion in cash and 14 pivotal clinical trials underway, Incyte offers an acquirer immediate revenue, margin expansion potential, and a deep oncology pipeline spanning KRASG12D, CDK2 inhibition, and mutCALR.

Ferroptosis, a major mechanism of non-apoptotic programmed cell death, critically regulates the homeostasis and functionality of peripheral CD4+ and CD8+ T cells. Here we demonstrate that in mouse, resistance of T cells to ferroptosis depends critically on the composition of standard rodent diets, and that dietary effects on ferroptosis have a crucial role in regulation of T cell homeostasis and immune responses.

Before treatment began, participants underwent neuroimaging. Instead of relying on a single modality, the researchers fused structural connectivity (how regions are physically wired) with functional connectivity (how regions co-activate at rest). The goal was not to throw every possible feature at a black box, but to learn a constrained pattern-what the authors call structure-function "covariation"-that carries the most predictive signal for outcome. In other words, the model tries to find the smallest set of connections that meaningfully forecasts symptom change.

The news is the latest sign of the FDA's heightened scrutiny of vaccines under Health Secretary Robert F. Kennedy Jr., particularly those using mRNA technology, which he has criticized before and after becoming the nation's top health official. Moderna received what's called a "refusal-to-file" letter from the FDA that objected to how it conducted a 40,000-person clinical trial comparing its new vaccine to one of the standard flu shots used today.

Although specific bacterial taxa have been associated with favourable clinical responses to immune checkpoint blockade (ICB) in cancer patients12,13,18,19,20,21,22, the mechanisms by which the intestinal microbiota influences anti-tumour immune responses remain poorly defined. Products of the microbiota, including metabolites23,24,25 and innate receptor ligands26, may reprogramme myeloid cells27, lowering the activation threshold for antigen presentation and thereby facilitating priming and activation of tumour-reactive T cells.

During viral infection and in the case of cancer, CD4+ helper T-cells release cytokines, or small signaling proteins, that activate and "give permission" to other immune cells to control and clear viral pathogens. In certain viral infections, such as lymphocytic choriomeningitis virus (LCMV), which is spread by infected rodents, CD4+ T-cells differentiate into different subpopulations, including one subset of progenitor CD4+ T-cells that replenish type 1 helper (Th1) and follicular helper (Tfh) T-cells.

For years, scientists have viewed cancer as a localized glitch in which cells refuse to stop dividing. But a new study suggests that, in certain organs, tumors actively communicate with the brain to trick it into protecting them. Scientists have long known that nerves grow into some tumors and that tumors containing lots of nerves usually lead to a worse prognosis.

A virus that sickens marine mammals has been detected in Arctic waters for the first time. Scientists used drones armed with petri dishes to collect samples of blow - the air and mucus whales expel from their blowholes - from whales in northern Norway. The team identified cetacean morbillivirus in samples from humpback whales ( Megaptera novaeangliae) and one sperm whale ( Physeter macrocephalus), though the humpbacks showed no symptoms of disease.

When Lisa Dutton was declared free of breast cancer in 2017, she took a moment to celebrate with family and friends, even though she knew her cancer journey might not be over. As many as one-third of people whose breast tumours are cleared see the disease come back, sometimes decades later. Many other cancers are known to recur in the years following an initial treatment, some at much higher rates.

Eduardo Vilar-Sanchez has spent more than 10 years pursuing a goal that seemed very distant, but which he now sees as a little closer: to develop a preventive vaccine against cancer. The physician and researcher is leading a study that presented the first promising results of a colon cancer vaccine in a small group of patients suffering from a rare disease that makes them 17 times more likely to develop colon cancer than the general population.

We knew that if you inject these nanoparticles into an animal model, the nanoparticles get taken up by antigen presenting cells and this resulted in increased regulatory T-cells and decreased inflammatory disease. However, we did not know how this happens,

As for side effects, the companies reported that little had changed from previous analyses; adverse events were similar between the two groups. The top side effects linked to the vaccine were fatigue, injection site pain, and chills. The results "highlight the potential of a prolonged benefit" of the vaccine combined with Keytruda in patients with high-risk melanoma," Kyle Holen, a senior vice president at Moderna, said. They also "illustrate mRNA's potential in cancer care," he said, noting that the company has eight more Phase 2 and Phase 3 trials going for mRNA vaccines against a variety of other cancers, including lung, bladder, and kidney cancers.

Laboratories turned to a smart workaround when COVID‑19 testing kits became scarce in 2020. They mixed samples from several patients and ran a single test. If the test came back negative, everyone in it was cleared at once. If it was positive, follow-up tests would zero in on who was infected. That strategy, known as group testing, saved valuable time, money, and resources.
