Holographic 3D Printing has the potential to Revolutionize Multiple Industries

Posted by in categories: 3D printing, chemistry, holograms

A pioneering technique shows how sound can be used to create entire objects quickly and at once. Researchers at Concordia have developed a novel method of 3D printing that uses acoustic holograms. And they say it’s quicker than existing methods and capable of making more complex objects.

The process, called holographic direct sound printing (HDSP), is described in a recent article in the journal Nature Communications. It builds on a method introduced in 2022 that described how sonochemical reactions in microscopic cavitations regions — tiny bubbles — create extremely high temperatures and pressure for trillionths of a second to harden resin into complex patterns.

Now, by embedding the technique in acoustic holograms that contain cross-sectional images of a particular design, polymerization occurs much more quickly. It can create objects simultaneously rather than voxel-by-voxel.

Team engineers New Enzyme to Produce Synthetic Genetic Material

Posted by in categories: bioengineering, biotech/medical, genetics

Discovery advances development of new therapeutic options for cancer and other diseases. A research team led by the University of California, Irvine has engineered an efficient new enzyme that can produce a synthetic genetic material called threose nucleic acid. The ability to synthesize artificial chains of TNA, which is inherently more stable than DNA, advances the discovery of potentially more powerful, precise therapeutic options to treat cancer and autoimmune, metabolic and infectious diseases.

A paper recently published in Nature Catalysis describes how the team created an enzyme called 10–92 that achieves faithful and fast TNA synthesis, overcoming key challenges in previous enzyme design strategies.

Inching ever closer to the capability of natural DNA synthesis, the 10–92 TNA polymerase facilitates the development of future TNA drugs.

The human spliceosome: Decade-long study reveals first blueprint of the most complex molecular machine inside every cell

Posted by in category: nanotechnology

Researchers at the Center for Genomic Regulation (CRG) in Barcelona have created the first blueprint of the human spliceosome, the most complex and intricate molecular machine inside every cell. The scientific feat, which took more than a decade to complete, is published in the journal Science.

Off the clothesline, on the grid: MXene nanomaterials enable wireless charging in textiles

Posted by in categories: energy, nanotechnology

The next step for fully integrated textile-based electronics to make their way from the lab to the wardrobe is figuring out how to power the garment gizmos without unfashionably toting around a solid battery. Researchers from Drexel University, the University of Pennsylvania, and Accenture Labs in California have taken a new approach to the challenge by building a full textile energy grid that can be wirelessly charged. In their recent study, the team reported that it can power textile devices, including a warming element and environmental sensors that transmit data in real-time.

Mesoporous MoS₂ strategy boosts efficiency and stability of perovskite solar cells

Posted by in categories: solar power, sustainability

The efficiency and performance of photovoltaics (PVs) have improved significantly over the past decades, which has led to an increase in the adoption of solar technologies. To further enhance the performance of solar cells, energy researchers worldwide have been devising and testing alternative design strategies, leveraging different materials and cell structures.

Stem cell-like approach in plants sheds light on specialized cell wall formation

Posted by in category: biotech/medical

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, similar to the way stem cells differentiate into different cell types. Using this method, the research team explored the banding patterns that increase the stability of plant cell walls—much like the corrugated patterns in cardboard—and how they are created. Additionally, the researchers revealed how the assembly of these structures can go astray in different mutant plant cells, which they said could ultimately inform methods to break down plant cells for biofuels.

Wearable ultrasound tech for long-term muscle monitoring expands applications for human-machine interfaces

Posted by in categories: biological, cyborgs, neuroscience, wearables

A key challenge in the effort to link brain activity with behavior is that brain activity, measured by functional magnetic resonance imaging (fMRI), for instance, is extraordinarily complex. That complexity can make it difficult to find recurring activity patterns across different people or within individuals.

In a new study, Yale researchers were able to take fMRI data, reduce its complexity, and in doing so, uncover stable patterns of activity shared across more than 300 different people. The findings, researchers say, are a promising step forward in uncovering biomarkers for psychiatric disorders.

The study was published Sept. 24 in the journal PLOS Biology.

Over a thousand online shops hacked to show fake product listings

Posted by in category: cybercrime/malcode

A phishing campaign dubbed ‘Phish n’ Ships’ has been underway since at least 2019, infecting over a thousand legitimate online stores to promote fake product listings for hard-to-find items.

Unsuspecting users clicking on those products are redirected to a network of hundreds of fake web stores that steal their personal details and money without shipping anything.

According to HUMAN’s Satori Threat Intelligence team that discovered Phish n’ Ships, the campaign has impacted hundreds of thousands of consumers, causing estimated losses of tens of millions of dollars.

This Is a Glimpse of the Future of AI Robots

Pick and place bots autonomously doing household chores. Progress! 🦾🤖


The idea of a robot that does a wide range of household chores, from unloading the dryer to folding laundry to cleaning up a messy table, has long seemed like pure science fiction—perhaps most famously embodied by the 1960s fantasy that was Rosey in The Jetsons.

Physical Intelligence, a startup in San Francisco, has shown that such a dream might actually not be so far off, demonstrating a single artificial intelligence model that has learned to do a wide range of useful home chores—including all of the above—by being trained on an unprecedented amount of data.
