We Finally Understand What Happened Before the Big Bang

For decades, we were taught the universe is 13.8 billion years old. Textbooks repeated it. Documentaries swore by it. Every model of cosmic history depended on it.
But now the numbers are breaking.

The James Webb Space Telescope is detecting galaxies that shouldn’t exist, stars older than our timeline allows, and cosmic structures so mature they overturn everything we thought we understood.
Reality is being rewritten in real time.

New evidence points to a universe that could be 26.7 billion years old – nearly double the age we believed. And if that’s true, then the biggest question becomes unavoidable.
What came before the Big Bang?

The answer is colder, emptier, and far stranger than anything in standard cosmology.
Get ready. We’re going back to the moment before everything.

This Changes Everything! What Euclid Saw in 1.2 Million Galaxies Will Surprise You

Euclid’s first data release is here — and it’s already transforming our understanding of galaxy evolution, black hole growth, and the hidden structure of the Universe. From secondary galactic nuclei to rare ionized systems and newly revealed dwarf galaxies, Euclid is opening a new chapter in cosmology. To learn more about Euclid’s First Data Release, you can watch our full video on YouTube.

Cellular senescence related gene signature predicts prognosis and immune features in skin cutaneous melanoma

Skin cutaneous melanoma (SKCM) is the deadliest skin cancer, with rising global incidence. Cellular senescence plays an essential role in tumorigenesis, progression, and immune modulation in cancer, however, its role in SKCM prognosis and immunotherapy response remains unclear.

We analyzed 279 senescence-related genes (SRGs) in 469 patients with SKCM from The Cancer Genome Atlas. A cellular senescence-related signature (CSRS) was constructed using univariate and LASSO Cox regression analyses. Kaplan-Meier survival curves and receiver operating characteristic (ROC) analyses were used to evaluate its predictive performance. Consensus clustering based on SRG expression stratified patients into distinct subgroups. External validation was performed using the GSE65904 dataset. We further assessed the association between CSRS, immune cell infiltration, and immunotherapy response. Additionally, immunohistochemistry validated the expression of prognosis-related SRGs and functional assays explored the role of RuvB-like AAA ATPase 2 (RUVBL2) in SKCM cells.

The CSRS effectively stratified patients with SKCM into high-and low-risk groups with significantly different survival outcomes and immune profiles. Moreover, our results suggest that higher levels of cellular senescence may enhance immunosurveillance and promote tumor suppression via a senescence-associated secretory phenotype-dependent mechanism. Based on the expression profiles of 113 SRGs, patients were classified into three distinct clusters, with Cluster 1 associated with the poorest prognosis. Among the identified SRGs, RUVBL2 was markedly upregulated in SKCM cells and its knockdown inhibited cell proliferation.
