Schematic illustration of MEMS-integrated twisted bilayer photonic crystals illuminated by right-handed circularly polarized and left-handed circularly polarized beams. Harvard engineers have built a ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes ...

A scheme for dynamically tuning the coupling between a series of resonators and waveguides provides a means of storing light on an integrated photonic chip for longer than is possible with ...

With 17 weight classes in boxing and four major sanctioning bodies that bestow world titles, keeping track of who holds each of the belts can be difficult -- especially when there are sometimes ...

Apr. 7, 2026 A gene called KLF5 may be a key force behind the spread of pancreatic cancer—but not in the way scientists expected. Rather than mutating DNA, it rewires how genes are turned on and off, ...

Microbiology is the study of microscopic organisms, such as bacteria, viruses, archaea, fungi and protozoa. This discipline includes fundamental research on the biochemistry, physiology, cell biology, ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

Nature and climate go hand in hand. Together, they form our life‑support system - giving us clean air, fresh water, the food we eat and so much more. Yet both are under threat. Earth Hour is a global ...

How to move from promises to results by Ella F. Washington Since the murder of George Floyd, in 2020, I’ve spoken with countless CEOs and chief human resources officers as they responded to the racial ...

Iron is one of the most important items, probably even more so than diamonds in Minecraft. You can obtain iron ingots by smelting the raw iron you get from ores, but it’s a manual process and ...
