Black hole vibes

2025-07-31
Kyoto, Japan -- Black holes embody the ultimate abyss. They are the most powerful sources of gravity in the universe, capable of dramatically distorting space and time around them. When disturbed, they begin to "ring" in a distinctive pattern known as quasinormal modes: ripples in space-time that produce detectable gravitational waves. In events like black hole mergers, these waves can be strong enough to detect from Earth, offering a unique opportunity to measure a black hole's mass and shape. However, precise calculation of these vibrations through theoretical methods ...

Actual distance travelled by migrating whales drastically underestimated

Whales are swimming further than previously estimated - up to 20% more - according to a new study published in Ecology. Co-authored by Griffith University’s Dr Olaf Meynecke, the study reveals traditional methods for calculating animal movement may be drastically underestimating the actual distance travelled, particularly for marine species such as whales. “For years, we've tracked whales using satellite tags, plotting their movements across oceans,” Dr Meynecke said. “But this research shows we’ve been looking ...

The eagles resistant to poisonous toads

2025-07-31
Kyoto, Japan -- In 1978, cane toads, which are native to South and Central America, were introduced for pest control to Ishigaki island in Okinawa prefecture in Japan. These poisonous toads secrete deadly toxins, killing enough of the predators in their new territories that they have been designated an invasive species. However, one predator on Ishigaki has proven resistant to the cane toads' poison. The crested serpent eagle, common across Asia but considered critically endangered in Japan where only about 200 individuals reside, has been observed feeding on the toads on the ...

Cancer's double agents: Fibroblasts both help and hinder immunotherapy

2025-07-30
Cancer-associated fibroblasts (CAFs) – critical but enigmatic players in tumors – exhibit "paradoxical" effects on immunotherapy, according to a new review in Clinical and Translational Discovery. While most CAFs suppress immune cells to accelerate cancer progression, certain subtypes actively restrain tumors. This duality stems from CAFs’ extreme heterogeneity, explaining why depleting all CAFs sometimes backfires by accelerating metastasis.   CAFs sabotage immunotherapy through multiple mechanisms: ...

THER: integrative web tool for tumor hypoxia exploration and research

2025-07-30
Tumor hypoxia refers to the gradual decrease in ATP production when oxygen levels drop below a critical threshold, contributing to malignant tumor development. Studies show hypoxia-induced changes play an indispensable role in tumor progression, enabling tumors to become invasive or metastatic. However, hypoxia's effects vary across tumor types, and these mechanistic differences remain unclear. To address this, we developed THER (https://smuonco.shinyapps.io/THER/), an online tool that allows analysis of hypoxia-associated transcriptomic data without requiring programming skills.

How sources of dietary fat influence cancer growth in obesity

2025-07-30
July 30, 2025, NEW YORK – Obesity elevates the risk for at least 13 major cancers, including those of the breast, colon and liver. It also impairs immune responses that target tumors and are stimulated by cancer immunotherapies. But it has long been unclear whether these effects stem from the sheer adiposity—or mass of fat—in people living with obesity or from the specific dietary fats they consume. Now, a decade-long study led by Ludwig Princeton’s Lydia Lynch and reported in the current issue of Nature ...
