Challenges in Hiring Recent College Graduates: A Survey Reveals Employer Concerns

January 14, 2024

A recent survey conducted in December 2023, involving 800 U.S. directors and executives responsible for filling open job positions, has shed light on some concerning trends in hiring recent college graduates. The findings indicate that nearly four in ten managers avoid hiring these graduates, citing concerns about their readiness for the professional world.

One particularly surprising statistic from the survey reveals that one in five employers reported instances of recent college graduates bringing their parents to job interviews. Additionally, 21% of employers noted candidates refusing to turn on their cameras during virtual interviews, which was perceived as a significant challenge.

Advancements at KSTAR: Paving the Way for Fusion Energy’s Future

January 14, 2024

The global fusion energy community eagerly awaits the International Thermonuclear Experimental Reactor (ITER)’s momentous first plasma, expected in 2025. While ITER takes center stage, smaller reactors worldwide are making groundbreaking strides in preparation for the next-generation energy project. Among these pioneering reactors stands the Korea Superconducting Tokamak Advanced Research reactor (KSTAR) in Daejeon, South Korea.

Since its inception in 2008, KSTAR has been a bastion of research into the fundamental principles of fusion energy, the same process that powers our Sun. By generating plasma temperatures exceeding a scorching 100 million degrees Celsius, KSTAR compels specific hydrogen isotopes to fuse, producing colossal amounts of energy.

Breakthrough Nanodrones Utilize Natural Killer Cells for Targeted Cancer Treatment

January 12, 2024

Researchers have achieved a significant breakthrough in cancer treatment by harnessing the potent capabilities of the body’s natural killer (NK) cells. These innovative nanodrones are designed to selectively target tumors, allowing NK cells to suppress cancer growth effectively. This discovery paves the way for the development of tumor-specific immunotherapies, particularly for challenging-to-treat cancers.

NK cells are specialized white blood cells known for their ability to destroy infected and diseased cells, including cancer cells, without prior exposure to a specific pathogen. Researchers from the Ulsan National Institute of Science and Technology (UNIST) in South Korea have unlocked the potential of NK cells by creating nanodrones that engage these cells and direct them to target and eliminate cancer cells.

GE Aerospace’s Hypersonic Engine Breakthrough Takes Flight

January 12, 2024

Last month, the race to develop reusable hypersonic aircraft heated up as GE Aerospace unveiled a groundbreaking advancement in high-speed jet engine design, potentially enabling conventional aircraft to reach speeds exceeding Mach 10. According to GE’s press release, the company achieved a world-first hypersonic dual-mode ramjet (DMRJ) rig test with rotating detonation combustion (RDC) in a supersonic flow stream. This breakthrough leverages rotating detonation combustion, a highly efficient power production method, within a dual-mode ramjet/scramjet engine.

Ramjets and scramjets are air-breathing jet engines that excel at high speeds, typically from around Mach 3 up to Mach 5 and beyond, but are less effective at lower speeds. GE’s achievement represents a significant step towards developing dual-mode ramjet/scramjets with extended range, especially when combined with a turbine-based combined cycle (TBCC) propulsion system.

Samsung Unveils Next-Generation Sensors to Elevate Machine Vision Technology

January 11, 2024

Samsung has recently introduced two cutting-edge sensors as part of its Isocell Vizion family, poised to revolutionize machine vision technology. These sensors have been meticulously crafted to elevate 3D imaging capabilities and enhance image clarity in motion, with one holding remarkable promise for facial recognition and iris biometrics applications.

The Isocell Vizion 63D stands out by incorporating Time-of-Flight (ToF) technology, which precisely measures the time taken by light to travel from the sensor, bounce off objects, and return to the sensor. This sophisticated technology plays a pivotal role in generating 3D representations of the surrounding environment, making it exceptionally valuable for applications like virtual and augmented reality, iris biometrics, facial detection, and gesture recognition. To craft a three-dimensional perspective, the sensor gauges the phase shift between emitted and reflected light, a distinguishing feature of iToF technology that ensures exceptional accuracy.

“Brainoware”: Biohybrid Computer Combining Human Brain Organoid and AI Shows Promise in Speech Recognition

January 11, 2024

In a groundbreaking development, researchers from the University of Indiana Bloomington (UIB) have introduced a new biohybrid computer named “Brainoware,” which merges a “brain organoid” with traditional artificial intelligence (AI). This innovative system demonstrated its potential by achieving 78% accuracy in a speech recognition task, highlighting the possibilities of enhancing computing capabilities with elements of human biology.

The rationale behind this endeavor stems from the remarkable energy efficiency of the human brain. While supercomputers require 20 megawatts of power for processing over a quintillion calculations per second, the human brain accomplishes equivalent tasks with a mere 20 watts. Inspired by this efficiency, scientists explored the idea of augmenting computers by integrating them with three-dimensional clusters of lab-grown human brain cells, known as brain organoids.

See-Through Wood: A Sustainable Future Material

January 10, 2024

Three decades ago, German botanist Siegfried Fink pioneered a revolutionary concept: creating transparent wood by bleaching plant cells. His breakthrough technique, published in a 1992 wood technology journal, remained dormant until materials scientist Lars Berglund stumbled upon it, sparking a renewed interest in transparent wood. Collaborating with researchers at the University of Maryland, Berglund and his counterparts at KTH Royal Institute of Technology in Sweden have now harnessed the potential of transparent wood for various applications.

Wood’s intricate structure consists of vertical channels resembling bundled straws held together by glue called lignin. To achieve transparency, researchers remove or modify lignin, leaving a milky-white skeleton of hollow cells. By filling these cells with a substance like epoxy resin that bends light similarly to cell walls, transparent wood is created. Despite its thin profile, transparent wood exhibits remarkable strength, outperforming plastic and glass in fracture and pressure tests.

Revolutionizing Biomedical 3D Printing: Duke University and Harvard Researchers Introduce Deep-Penetrating Acoustic Volumetric Printing

January 10, 2024

A groundbreaking advancement in 3D printing within the human body has been achieved by a collaborative team of researchers from Duke University and Harvard Medical School. Their innovative approach involves utilizing ultrasound waves to solidify an injectable biocompatible ink, as detailed in a recent paper published in the journal Science.

Building upon a previously developed photo-sensitive ink that hardens when exposed to light, the researchers sought to overcome the limitation of light penetration, which extends only a few millimeters into the patient’s tissue. The new technique, termed “deep-penetrating acoustic volumetric printing” (DVAP), leverages the sono-thermal effect, where soundwaves are absorbed, increasing the temperature and subsequently solidifying the ink.
