Demonstrating a 1-Pbps orbital angular momentum fiber-optic transmission
Space-division multiplexing (SDM) technology has a promising role in overcoming the so-called "capacity crunch" of existing single mode fiber (SMF). Now, researchers in China experimentally demonstrated an orbital-angular-momentum (OAM) mode based SD.....»»
Chiral transmission by an open evolution trajectory in a non-Hermitian system
In non-Hermitian systems, two or more eigenvalues and eigenstates of a resonant system coalesce at Exceptional points (EPs). Dynamic encircling of EPs has received significant interest in recent years, as it leads to highly nontrivial phenomena, such.....»»

Could fiber optic cable help scientists probe the deep layers of the moon?
An increasing number of seismologists are using fiber optic cables to detect seismic waves on Earth—but how would this technology fare on the moon, and what would it tell us about the deep layers of our nearest neighbor in space?.....»»
Researchers: We can"t say yet if grid-breaking thunderstorms are getting worse, but we shouldn"t wait to find out
On February 13, six transmission line towers in Victoria were destroyed by extreme wind gusts from thunderstorms, leading to forced electricity outages affecting tens of thousands of people. The intense winds knocked trees onto local power lines or t.....»»
Blocking fertilization of parasite-causing malaria opens new doors in eradication efforts
More than 400 people develop malaria every minute, and it can be fatal if not diagnosed and treated at the first sign of symptoms. Eliminating the disease will require interventions that stop the transmission of the parasite from mosquitoes to humans.....»»
Unlocking the heat in mosquito modeling: Exploring disease transmission under climate change
Thermal adaptation is the ability of organisms to adjust their life history traits as the temperature changes. In the case of mosquitoes, these traits can determine their risk of transmitting mosquito-borne diseases and how this risk might change in.....»»
Temperature, humidity may drive future transmission of parasitic worm infections
As climate changes, temperature isn't the only factor to influence the spread of infectious diseases. Humidity plays a role, too, according to new research published this week (Feb. 25) in Ecology Letters......»»
