Researchers have made significant advances in epigenetic editing, a technique that modifies gene expression without changing the DNA sequence. These developments enable more precise control over gene activity, opening new avenues for treating diseases and studying fundamental biology. The progress marks a turning point in the field, bringing epigenetic therapies closer to clinical application.

A new study published in Nature reveals that contrary to previous assumptions, tall and small trees face similar levels of vulnerability to drought. Researchers analyzed global data and found no consistent size-based difference in drought-induced mortality. This finding challenges forest management practices and climate models that often treat tree size as a key factor in drought resilience.

The United Nations' Space Object Database, designed to promote transparency and reduce tensions over space activities, has mysteriously gone offline. The outage raises concerns about international trust and the accessibility of crucial orbital data needed to prevent misunderstandings or conflicts in space.

Researchers are using machine learning to generate new approaches to Fermat's last theorem, a famous problem solved in the 1990s. The AI explores proof strategies and related conjectures, potentially accelerating discovery in pure mathematics. This collaboration highlights AI's growing role in theoretical fields.

Deutsche Telekom is integrating artificial intelligence across its network operations to improve efficiency, customer service, and predictive maintenance. The initiative highlights how telecom companies are leveraging AI to modernize infrastructure and adapt to growing data demands. This shift could set a precedent for broader industry adoption of AI-driven telecom solutions.

Researchers have made new progress in developing functional sperm from stem cells in the lab. This advance could eventually offer new fertility treatments for people with infertility due to genetic or medical conditions. While still far from clinical use, the work marks a significant step toward addressing male infertility.

Dolly the sheep, the first mammal cloned from an adult cell, was born in 1996 and died in 2003. This anniversary reflects on her profound impact on cloning research, ethical debates, and public understanding of biotechnology. Her legacy continues to influence reproductive science and bioethics today.

A new analysis of over 70,000 studies found that preprints and peer-reviewed papers have similar rates of errors, challenging the common perception that preprints are less reliable. Researchers compared error rates and found no significant difference, suggesting preprints can be a trustworthy source of scientific information. This could accelerate the use of preprints in decision-making and policy.

New research, published in Nature, quantifies the severe losses Hannibal's army and elephants suffered during the crossing of the Alps. The study uses environmental data to show that cold, hunger, and harsh terrain killed many troops and animals. This provides fresh insight into one of history's most famous military maneuvers and its human and animal cost.
