Cutting to the Core of How 3D Structure Shapes Gene Activity
In biology textbooks and beyond, the human genome and DNA therein typically are taught in only one dimension. While it can be helpful for learners to begin with the linear presentation of how stretches of DNA form genes, this oversimplification undersells the significance of the genome’s 3D structure. Problems with this 3D structure are associated with many diseases including developmental disorders and cancer. Scientists at Sanford Burnham Prebys and colleagues in Hong Kong published findings June 27, 2025, in Genome Biology demonstrating a new approach for better understanding the human genome’s 3D structure and its influence.

Nobel Laureate Conversation: Prof. Pierre Agostini
Prof. Pierre Agostini was awarded the 2023 Nobel Prize in Physics for demonstrating experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter, along with Ferenc Krausz and Anne L’Huillier. Their ingenious experimental designs and rigorous measurement techniques turned attosecond pulses into a new probe for exploring the microscopic behavior of matter. From electron rearrangements inside atoms to the ultrafast transfer of energy in molecules, attosecond technology is reshaping our understanding of light-matter interactions. Today, its impact extends far beyond fundamental physics, enabling real-time tracking of chemical reactions, the development of novel materials, and even the study of ultrafast processes in life sciences. Agostini’s scientific achievement lies not only in the technical breakthrough itself, but in opening a door to an unexplored world—where time is sliced into its finest fragments, and every instant of an electron’s mot

Nobel Laureate Conversation: Prof. J. Michael Kosterlitz
Prof. J. Michael Kosterlitz is the 2016 Nobel Prize Winner for Physics. Through his career, he overturned the conventional understanding that two-dimensional systems could not undergo phase transitions due to thermal fluctuations, along with David Thouless. They showed that vortex-antivortex pairs play a key role in phase transitions, leading to a topological phase transition now known as the Kosterlitz-Thouless (KT) transition. He is a true trailblazer in breaking the disciplines’ boundary, his idea of implementing topology—a subfield of mathematics—in exploring physics has been transformative. He is an adventurer who cares most about the fun of exploring science. Scientists are paid to have fun, said by him.

Tipping the Balance: How Hidden Chemical Threats Are Reshaping Ecosystems
Since the onset of the Anthropocene, chemical pollution has become a major global threat to biodiversity across all ecosystems. It is no longer a problem of simple cause and effect. A new study reveals that pollutants can trigger sudden and dramatic ecological changes, acting like hidden levers that push ecosystems past points of no return. These shifts often happen without warning—disrupting biodiversity, altering food webs, and weakening natural resilience. Rather than following a predictable pattern, the impact of chemical contaminants often unfolds through complex, nonlinear dynamics. To tackle this, researchers propose an integrated framework that blends real-time monitoring with predictive modeling, offering a sharper lens to detect early warning signs and prevent irreversible damage. This approach could transform how we safeguard global ecosystems in the face of escalating environmental stress.
