New psychology findings suggest that attractive students earn higher grades in school, but for female students, this beauty premium disappears when classes are taught remotely. The findings were published in the journal Economic Letters.
A large body of research suggests that physical appearance has an impact on a personâs success. For example, attractive people tend to earn more money and report higher life satisfaction than less attractive people. Interestingly, scholars have yet to agree on the explanation behind this beauty premium.
One account suggests that the beauty advantage can be explained by discrimination. For example, employers may inherently favor attractive over unattractive workers. Another perspective suggests that beauty is a productivity-enhancing attribute. This view suggests that attractiveness lends itself to higher productivity, for example, through increased self-confidence.
The James Webb Space Telescope has revolutionized the way we look at the universe in less. than a year. Since its launch on December 25, 2021 multiple images captured by the largest. telescope with potentially the highest infrared resolution and sensitivity have been going viral. around the globe. James Webb is no doubt the most advanced telescope in human history. The. telescopeâs integrated science instrument module or ISIM framework provides it with electrical. power, computing framework, cooling capability and structural stability. The ISIM also holds the. four science instruments and the guide camera of the telescope. The infrared imager NIRICam. serves as the Observatoryâs wavefront sensor while the NIRISpec performs spectroscopy over. the same wavelength range as that of NIRICam. The Mid-Infrared Instrument measures the mid. to long infrared wavelengths and the Fine Guidance Center and Near Infrared Imager and. Slitless Spectrograph is used to stabilize the line of sight during the science observations. So far. the images and data received from the JWST are well worth the ten billion spent on building this. miraculous invention. The first ever in ages from the telescope were revealed to the world on. July 12, 2022 and experts believe these pictures from the largest and most powerful telescope. in the world demonstrate Webb at its absolute best, fully prepared to further unravel the infrared universe. These included images of cosmic cliffs in the carina nebula, exoplanet WASP-06b. southern ring nebula, Stephenâs quintet and the brilliant deep field view of the universe. But. these were just the first batch, since then the James Webb Telescope has provided scientists. with even more dazzling and awe-inspiring images of the cosmos. Some of these images have. left astronomers and cosmologists quite confused. A flood of astronomical papers has been. published since the revelation of these images and data from the JWST, a few of these papers. have incited panic among the cosmologists. But what exactly is the reason behind this wave of. panic? Well, itâs the assumption that the findings of James Webb Space Telescope are blatantly. and repeatedly contradicting the Big Bang Theory. In order to better understand whatâs going. on, we first need to understand what the Big Bang exactly is.

Physicists are devising clever new ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But so far, theyâve seen no signs of exotica.

In a study recently published in the journal Nature Biomedical Engineering, researchers from Kanazawa University use a method called âlasso-graftingâ to design therapeutics with enhanced longevity and brain penetration.
Cell growth and repair are stimulated by biomolecules known as cytokines and growth factors. Unfortunately, delivering adequate concentrations of these molecules to the brain for treating neurological conditions like Alzheimerâs disease is challenging as they are either cleared out of the blood very quickly or do not penetrate neural tissue effectively.
A research team led by Kunio Matsumoto and Katsuya Sakai at Kanazawa University in collaboration with Junichi Takagi, Osaka University and Hiroaki Suga, the University of Tokyo has now used a technique called âlasso-graftingâ to design molecules that replicate growth factors with longer retention in the body and brain penetration.
An in-depth survey of the various technologies for spaceship propulsion, both from those we can expect to see in a few years and those at the edge of theoretical science. Weâll break them down to basics and familiarize ourselves with the concepts. Note: I made a rather large math error about the Force per Power the EmDrive exerts at 32:10, initial tentative results for thrust are a good deal higher than I calculated compared to a flashlight.
The UK @Ministry of Defence #Defence Science and #Technology Laboratory (Dstl) has hosted the UKâs first high-powered, long-range #Laser Directed Energy Weapon (LDEW) trial on its ranges at Porton Down.
The trials involve firing the UK #DragonFire demonstrator at a number of targets over a number of ranges, demanding pinpoint accuracy from the beam director.
The trial improves the UKâs understanding of how high-energy lasers and their associated technologies can operate over distance and defeat representative targets. The ability to deliver high levels of laser power with sufficient accuracy are two of the major areas that need to be demonstrated in order to provide confidence in the performance and viability of LDEW systems.
The programme has developed a UK Sovereign âCentre of Excellenceâ staffed with experts from multiple fields. LDEW have the potential to provide lower cost lethality, reduced logistical burden and increased effectiveness when compared to other weapon systems â the technology could have a huge effect on the future of Defence operations.
Plastic waste is clogging up our rivers and oceans and causing long-lasting environmental damage that is only just starting to come into focus. But a new approach that combines biological and chemical processes could greatly simplify the process of recycling it.
While much of the plastic we use carries symbols indicating it can be recycled, and authorities around the world make a big show about doing so, the reality is that itâs easier said than done. Most recycling processes only work on a single type of plastic, but our waste streams are made up of a complex mixture that can be difficult and expensive to separate.
On top of that, most current chemical recycling processes produce end products of significantly worse quality that canât be recycled themselves, which means weâre still a long way from the goal of a circular economy when it comes to plastics.
A new type of material can learn and improve its ability to deal with unexpected forces thanks to a unique lattice structure with connections of variable stiffness, as described in a new paper by my colleagues and me.
The new material is a type of architected material, which gets its properties mainly from the geometry and specific traits of its design rather than what it is made out of. Take hook-and-loop fabric closures like Velcro, for example. It doesnât matter whether it is made from cotton, plastic or any other substance. As long as one side is a fabric with stiff hooks and the other side has fluffy loops, the material will have the sticky properties of Velcro.
My colleagues and I based our new materialâs architecture on that of an artificial neural networkâlayers of interconnected nodes that can learn to do tasks by changing how much importance, or weight, they place on each connection. We hypothesized that a mechanical lattice with physical nodes could be trained to take on certain mechanical properties by adjusting each connectionâs rigidity.
