Using Magnets To Toggle Nanolasers Leads to Better Photonics

Plasmonic Laser Nanodot Array

A plasmonic laser is turned on (top) and off (bottom) by switching the magnetization of a nanodot array. The zoomed insets show the magnetic field around a single nanodot.

Webb Sunshield Deployment Animation

Credit: NASA’s Goddard Space Flight Center Conceptual Image Lab With Webb’s first major structural deployments completed and the observatory’s Deployable Tower Assembly extended, we are taking a step back to learn more about Webb’s sunshield. Observatory Project Scientist Michael McElwain, from NASA’s Goddard Space Flight Center, provided these thoughts: “The Webb telescope and science instruments … Read more

Webb Space Telescope’s Deployable Tower Assembly Extends in Space

Webb Central Tower Deploymemt

By NASA December 30, 2021 Webb Central Tower deploymemt. Credit: NASA’s Goddard Space Flight Center Conceptual Image Lab Yesterday afternoon, the Webb team successfully extended the observatory’s Deployable Tower Assembly (DTA), creating critical distance between the two halves of the spacecraft. The DTA extended about 48 inches (1.22 meters), putting room between the upper section … Read more

Scientists Discover How Toxoplasma Parasites in the Brain Manipulate Host Cells To Survive

Toxoplasma-Infected Human Cell

A Toxoplasma-infected human cell moments before it bursts. Credit: WEHI WEHI researchers have discovered how dormant Toxoplasma parasites in the brain manipulate their host cells to ensure their own survival. The researchers showed that the parasites were able to lay dormant and undetected inside neurons (brain cells) and muscle cells by releasing proteins that switch … Read more

“A True Cosmic Monster!” Violent High-Frequency Oscillations Captured in Gigantic Eruption of a Neutron Star

"A True Cosmic Monster!" Violent High-Frequency Oscillations Captured in Gigantic Eruption of a Neutron Star

Credit: RUVID An international scientific group with outstanding Valencian participation has managed to measure for the first time oscillations in the brightness of a neutron star – magnetar – during its most violent moments. In just a tenth of a second, the magnetar released energy equivalent to that produced by the Sun in 100,000 years. … Read more

Innovative X-Ray Imaging Directly Shows COVID-19 Can Cause Vascular Damage to the Heart

Heart Tissue Severe COVID-19

Vascular network (red) in healthy heart tissue (left) and in severe Covid-19 (right). Due to faulty reforming of the network as a result of Covid-19, numerous branches, splits and even loops develop in the capillaries, which can be analyzed mathematically. Credit: M. Reichardt, P. Møller Jensen, T. Salditt Interdisciplinary research team from Göttingen University and … Read more
