Sleep Is Vital to Remember People's Faces and Names Shows Recent Study

Uninterrupted deep sleep was crucial to this progress. Nathan Whitmore, a PhD candidate in the Interdepartmental Neuroscience Program at Northwestern said, “It’s a new and exciting finding about sleep, because it tells us that the way information is reactivated during sleep to improve memory storage is linked with high-quality sleep .” Memory reactivation did not benefit and may even be harmful to study participants with EEG data (a recording of electrical activity in the brain picked up by electrodes on the scalp) that indicated interrupted sleep. The reactivation resulted in a relative improvement of a little over 1.5 more names recalled in those who slept uninterrupted throughout the specif

Scientists Tested a Well Known Colourful Jumping Spider to Find That It Is Colorblind.

The males of this species have furry red crowns and legs. They perform courtship dances to attract their female counterparts. "We assumed they were using colour for communication. But we didn't know if their visual system even allowed them to see those colours," said David Outomoro , a researcher associated with the study. The biologists collected spiders for lab study in Germany. They used microspectrophotometry to identify the sensitivity of their photoreceptors (light-sensing cells) towards the light of different colours and wavelengths . But, they found no evidence for red photoreceptors.  Microspectrophotometry is a technique used to measure the absorption and transmission of a light spectrum. This can be measured through a microspectrophotometer. Here, the t

China's Chang'E-5 Moon Lander Has Returned With Samples That Contain Water

There are numerous things that astronauts do in space and water is important for a few among those. It is also essential for astronaut landings, survival, and other purposes such as the production of rocket fuel. Researchers in China discovered the first signs of the  presence of water on the moon’s surface . This was done with help of the data obtained from Chang’E-5 lander’s lunar mineralogical spectrometer (LMS).  Professors  LIN Yangting and LIN Honglei of the Chinese Academy of Sciences' Institute of Geology and Geophysics (IGGCAS) were the ones who made the discovery. The study also included researchers from CAS's National Space Science Center, the University of Hawai'i at Mānoa, CAS's Shanghai Institute of Technical Physics, and Nanjing University.

US Researchers Make Flexible OLED Display Screen Using 3D Printing for the First Time

Image credit: University of Minnesota                                       The researchers at the University of Minnesota Twins Cities have developed a fully 3D-printed, flexible OLED display using a customised printer that can print objects for you. This finding can help to produce low-cost OLED displays in the coming years, instead of technicians using costly microfabrication facilities to construct small-scale structures such as computer chips, smartphone displays, etc. The detailed study is published in Science Advances . OLED Technology- Overview OLED stands for Organic Light-Emitting Diode- a technology that uses LEDs to produce light by organic molecules. This technology helps to create the world’s best display panels. Organic displays are prepared by placing thin films of organic semiconductors such as silicon or gallium arsenide between two conductors. These films emit a bright light when an electric current is applied. Each pixel emits its own light and is controlled indivi

New Research Shows That Dogs Can Differentiate Between Different Human Languages

The close association over several centuries may have also given them an extraordinary ability to understand human languages. New research published in the journal, NeuroImage has revealed that dogs can actually distinguish between different human languages. The research was conducted by  Laura Cuaya , a neurobiologist at Eötvös Loránd University , and her team in Hungary.  Analyses of Dogs' Auditory Abilities Cuaya and her team trained 18 dogs including Kun-Kun (Cuaya's own pet), to lie motionless inside the MRI machine so their brains could be scanned while listening to the audio recordings of the human speech.  A dog trained to lie motionless for a MRI scan.

In the machine, each dog was exposed to an excerpt from a popular children's book, ‘The Little

Scientists conducted an experiment in the lab that explains why the Sun is sooooo hot!

Source: Solar Dynamics Observatory, NASA One of the major mysteries of solar physics is why the Sun's corona, the outermost part of its atmosphere reaches temperatures of several million degrees Celsius . A "hot" path leading to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves move at the same speed, explains this effect. A team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) , a German national lab, developed a laboratory model and for the first time experimentally confirmed the theoretically predicted behaviour of these plasma waves – called Alfvén waves. This was done in an experiment using the molten alkali metal rubidium and pulsed high magnetic fields, as reported in the journal Physical Review Letters. In solar physics, it is now comm

A Recent SpaceX Resupply Mission Sent P&G's Laundry Detergent and a Skin Printer to Space

The Dragon spacecraft separated from Falcon 9 and landed autonomously on the space station on Wednesday, December 22 2021, around 4:30 a.m., and will remain there for a month. Among the 6500 pounds of materials that the spacecraft launched from the Kennedy Space Center in Florida were supplies for the crew, a skin bioprinter, and even a detergent . Skin Bioprinting Bandages Skin bioprinting is a new approach for creating artificial skin from natural and synthetic building blocks. This process uses biological molecules and cell viability (a measure of live and healthy cells in a population) to print tissue structures. Skin reconstruction via burns is one of the applications of bioprinting that has been developing in the past years. However, it still needs a large bioprinter to print a tissue, allow
