For centuries, climate changes in the Indian Ocean closely followed the Pacific, but that relationship is now weakening. Over the past 400 years, climate conditions in the tropical Indian Ocean generally changed along with those in the Pacific. In other words, shifts in Pacific climate have historically had a strong influence on what happens in […]
Two DNA Molecules Should Repel. Instead, They “Zip” Together
Scientists have revealed how tiny metal ions help DNA molecules overcome electrical repulsion and “zip” together with striking precision. DNA molecules carry the same negative charge, so they would normally be expected to push apart. Inside living cells, however, DNA must sometimes come together for processes such as genetic recombination, gene silencing and cancer development. […]
The Story of How Wolves Became Dogs Is Stranger Than We Thought
For 15,000 years, humans and dogs have been changing together, creating one of evolution’s most remarkable partnerships. Dogs have long been known as “man’s best friend,” and archaeology suggests that bond reaches deep into prehistory. Dogs have been discovered buried beside humans in graves dating back 14,000 years. They also appear in ancient artwork from […]
Harvard Scientists Use Tiny Sound Waves To Protect Quantum Information
The same tiny vibrations that carry quantum information across a chip could also keep that information from fading away. Quantum technologies face a persistent problem: qubits are extraordinarily sensitive to disturbances from their surroundings. Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have now protected a qubit using mechanical […]

Einstein’s Gravity Just Passed a Strange New Quantum Test
An experiment comparing falling and stationary rubidium atomic waves found a quantum phase difference consistent with Einstein’s equivalence principle. A rubidium atom can behave as a wave that researchers can split between two paths. This allows the same atom to effectively follow both paths at once, without being broken into pieces. Physicists have now used […]
Researchers Uncover a Hidden Trigger Behind Chronic Inflammation
The findings offer new insights that could help guide the development of future therapies. A protein called human resistin may help flip on one of the immune system’s most powerful inflammatory switches. Researchers at Johns Hopkins Medicine found that resistin can activate a pathway involved in chronic inflammation, a process linked to conditions including cardiovascular […]
