Scientists craft embryo model mimicking early human blood development

Posted by in categories: bioengineering, biotech/medical

The model can help evolve “better methods for growing cells for blood transfusions, novel cell therapies, and hematopoietic stem cell transplants.”


Remarkably, heX-Embryoid models developed structures akin to blood islands, the initial sites supporting the generation of blood cells in developing embryos. The study identified progenitors for red blood cells, platelets, and various white blood cell types—a pivotal advancement in the field, according to the team.

Researchers claim the model successfully replicated a process closely resembling the initial stages of blood production in humans. “This is exciting because there are extensive possibilities to apply this model to better understand how blood is formed and develop better methods for growing cells for blood transfusions, novel cell therapies, and hematopoietic stem cell transplants,” said Mo Ebrahimkhani, senior author and an associate professor at the Pittsburgh Liver Institute and the Department of Bioengineering at Pitt, in a statement.

Can Signs of Life be detected from Saturn’s Frigid Moon?

Posted by in categories: energy, physics, space

Enceladus’ ice plumes may hold the building blocks of life. Researchers have shown unambiguous laboratory evidence that amino acids transported in the ice plumes of Saturn’s moon, Eceladus, can survive impact speeds of up to 4.2 km/s, supporting their detection during sampling by spacecraft.

As astrophysics technology and research continue to advance, one question persists: is there life elsewhere in the universe? The Milky Way galaxy alone has hundreds of billions of celestial bodies, but scientists often look for three crucial elements in their ongoing search: water, energy and organic material. Evidence indicates that Saturn’s icy moon Enceladus is an ‘ocean world’ that contains all three, making it a prime target in the search for life.

During its 20-year mission, NASA’s Cassini spacecraft discovered that ice plumes spew from Enceladus’ surface at approximately 800 miles per hour (400 m/s). These plumes provide an excellent opportunity to collect samples and study the composition of Enceladus’ oceans and potential habitability.

Hyundai and Kia boast another breakthrough, unveiling new tire with retractable ‘snow chains’

Posted by in categories: engineering, sustainability, transportation

Weeks after introducing a potentially game-changing “Uni-wheel” drive system for EVs, Hyundai and Kia are showing off another next-generation technology to keep EV drivers safer during inclement weather. Today, Kia and Hyundai introduced a new snow chain-integrated tire that utilizes shape memory alloy modules inside the wheel. See how this incredible new tech works in the video below.

As EVs continue to saturate the global automotive market, their respective technologies are evolving to benefit consumers. Now more than ever, these electric vehicles drive farther, charge faster, and come equipped with exciting new technologies like vehicle-to-load (V2L) capabilities and Plug & Charge.

Hyundai Motor Group has been one of the early proponents of such technologies, featuring them in EVs atop its E-GMP platform. In fact, Hyundai and Kia especially have rolled out some exciting technologies throughout the electric mobility segment and allocated considerable funds to R&D to explore new engineering breakthroughs.

Embedding nanodiamonds in polymer can advance quantum computing and biological studies

Posted by in categories: biological, computing, nanotechnology, particle physics, quantum physics

A nitrogen-vacancy (NV) center is a defect in the crystal structure of diamond, where a nitrogen atom replaces a carbon atom in the diamond lattice and a neighboring site in the lattice is vacant. This and other fluorescent defects in diamond, known as color centers, have attracted researchers’ attention owing to their quantum properties, such as single-photon emission at room temperature and with long coherence time. Their many applications include quantum information encoding and processing, and cell marking in biological studies.

Microfabrication in diamond is technically difficult, and nanodiamonds with color centers have been embedded in custom-designed structures as a way of integrating these quantum emitters into photonic devices. A study conducted at the University of São Paulo’s São Carlos Institute of Physics (IFSC-USP) in Brazil has established a method for this, as described in an article published in the journal Nanomaterials.

“We demonstrated a method of embedding fluorescent nanodiamonds in designed for this purpose, using two-photon polymerization [2PP],” Cleber Mendonça, a professor at IFSC-USP and last author of the article, told Agência FAPESP. “We studied the ideal concentration of nanodiamond in the photoresist to achieve structures with at least one fluorescent NV center and good structural and optical quality.” The photoresist is a light-sensitive material used in the fabrication process to transfer nanoscale patterns to the substrate.

55 years ago, the ‘Mother of All Demos’ foresaw modern computing

Posted by in categories: computing, engineering, food, sustainability

Engelbart grew up on a small farm in Southeast Portland where his father operated a radio store.

He graduated from Franklin High School in 1942 and enrolled at Oregon State College, now called Oregon State University, to study electrical engineering.

When World War II interrupted his studies, he spent two years working as a Navy radio and radar technician in the Philippines.
