Sharrow has redesigned the common marine propeller by replacing the usual blades with gently twisted loops that promise to eliminate efficiency-sapping tip vortices and cavitation. Put simply, less energy is wasted, leading to claimed efficiency boosts of up to 30%, not to mention smoother, quieter overall performance.

Not only has Sharrow’s 150-patent-deep design won a host of major awards from the marine and tech industries, it’s been put to the test on numerous vessels, both internally and by third-party reviewers, with some intriguing results.

The first time we took a look at Sharrow’s unique propeller design, we noted that the one big drawback seemed to be price. At about US$5,000 a pop to start, they were an estimated 10 times more than a typical propeller, a steep upfront investment that might be difficult to recoup even with a 30% efficiency boost.

Researchers at Princeton University have developed a cement paste that is 5.6 times stronger than cement, mortar, and other conventional cement-based construction materials.

The paste features a tubular architecture inspired by the structure of human cortical bone, which forms the outer layer of the femur (thigh bone).

“Cement paste deployed with a tube-like architecture can significantly increase resistance to crack propagation and improve the ability to deform without sudden failure,” according to the researchers.

Since 5G began its rollout in 2018 or 2019, fifth-generation wireless networks have spread across the globe to cover hundreds of millions of users. But while it offers lower latency than precursor networks, 5G also requires more base stations. To avoid installing unsightly equipment on more and more shared spaces, Japanese companies are developing transparent glass antennas that allow windows to serve as base stations that can be shared by several carriers.

Because 5G networks include spectrum comprising higher frequencies than 4G, base stations for 5G networks serve a smaller coverage footprint. Which means more base stations are needed compared to 4G. Due to a lack of installation spots and the high cost of rolling out 5G networks, carriers in Japan have been sharing mobile infrastructure.

Last month the Tokyo-based communications company JTower announced the deployment of the new glass antenna, created in part by glassmaker AGC (one of the world’s largest) and the mobile carrier NTT Docomo. The first was installed on a window in Tokyo’s Shinjuku district.

According to a Chinese state-sanctioned study, signals from SpaceX Starlink broadband internet satellites could be used to track US stealth fighters, such as the F-22.

They can claim that all they want but the reality is: It’s not that useful militarily, and if it were, Beijing almost certainly wouldn’t let anyone blab about it.

The research details how the academics were able to recognize the rough location of a commercial drone by observing disturbances in electromagnetic signals from Starlink satellites caused by aircraft passing through them. The system could “provide significant advantages in detecting small and stealth targets,” the team claimed.

The academics, led by professor Yi Jianxin from Wuhan University’s School of Electronic Information, launched [paywall] a commercial DJI Phantom 4 Pro drone and sent it over the coast near the Chinese city of Guangdong. The researchers chose the drone as they estimated it has the same radar signature as a modern F-22 fighter.

The 155-year-old Campbell Soup Company plans to drop “soup” from its corporate name, rebranding as The Campbell’s Company. More consumers are reaching for snacks and ditching ready-to-serve soups, and the company has bought up other food lines to grab them.

In addition to its lineup of soups, Campbell now owns snack brands like Goldfish, Snyder’s of Hanover, Cape Cod, Pepperidge Farm and others. Campbell also recently bought Sovos Brands, maker of popular Italian food brands like Rao’s sauces.

“This subtle yet important change retains the company’s iconic name recognition, reputation and equity built over 155 years while better reflecting the full breadth of the company’s portfolio,” Campbell CEO Mark Clouse said Tuesday in a statement. The name change is subject to shareholder approval at the company’s annual meeting in November.

Israel destroyed a secretive missile production facility in northwest Syria last week in an attack that included inserting special operations forces by helicopter to retrieve equipment and documents, media outlets are reporting. The new details shed light on an attack initially described as only an airstrike. Not only did the raid strike at the heart of the Iranian military presence in Syria, but it also sent a clear message to Tehran that the Israel Defense Forces (IDF) can and will attack deep underground complexes with ground troops that it otherwise cannot destroy from the air.

The raid, which took place September 9, “obliterated” the facility, located in northwestern Syria near the Lebanese border, The New York Times reported, citing unnamed American and other Western officials. “A number of people” were killed at the site, those sources said. It is located about 140 miles north of Israel.

Multispectral imaging is a way of capturing a digital image using non-visible wavelengths such as ultraviolet and infrared (click here to learn more). Where medieval manuscripts are concerned, UV imaging in particular can make faded or effaced text legible. This is because most medieval inks (including that used to write the Voynich Manuscript) have a significant iron component. This allows the ink to “bite” into the surface of the parchment rather than sliding off of it. When ink is scraped away or fades, the molecular bond remains, and the faded text may therefore fluoresce when exposed to UV bandwidths. This technology has proven invaluable in helping scholars read palimpsests and damaged manuscripts such as the Archimedes Palimpsest and the Syriac Galen Palimpsest. Could such imaging of the Voynich Manuscript help reveal its secrets?

Via testing with a skin stand-in, a trio of physicists at Technical University of Denmark has ranked the types of paper that are the most likely to cause a paper cut. In an article published in Physical Review E, Sif Fink Arnbjerg-Nielsen, Matthew Biviano and Kaare Jensen tested the cutting ability and circumstances involved in paper cuts to compile their rankings.

Paper cuts occur through the handling of paper products. In addition to the nuisance factor due to the sudden flow of blood, there is also often a great deal of pain involved. In this new effort, the researchers noted that most research done on the topic revolves around infection factors. They chose instead to focus on the types of paper most likely to cause a cut, thereby allowing paper users a means to reduce their chances of an injury.

To test the cutting ability of different types of paper, the researchers used ballistics gelatin as a stand-in for skin. They then attempted to cut the gelatin using multiple types of paper. They noted the sturdiness and thickness of the paper, and the angles that were involved when cutting occurred.

This particular topic piqued my interest after seeing negative feedback about the quality of tracking on services like AllTrails and Strava. Users often complain about inaccurate routes, inaccurate mapping, “incorrect” elevations, “wrong” distances and more.

An international team of scientists has developed a drug delivery system that could one day treat human brain aneurysms in a way without the need for traditional surgery.

The team said it built billions of tiny simple magnetic nanorobots – each 300nm in diameter, or about a twentieth the width of a human red blood cell – that contain clotting medications. After injecting several hundred billion of these into a rabbit’s artery, the scientists used magnets and medical imaging technology to cause the bots to cluster together inside an aneurysm, according to the boffins.

The bots were then heated to their melting point. The process released a naturally occurring blood-clotting protein to prevent or stop the aneurysm bleeding into the brain, the researchers noted.

Researchers at The University of Texas MD Anderson Cancer Center have shown that therapeutically restoring ‘youthful’ levels of a specific subunit of the telomerase enzyme can significantly reduce the signs and symptoms of aging in preclinical models. If these findings are validated in clinical trials, they could have important therapeutic implications for age-related diseases such as Alzheimer’s, Parkinson’s, heart disease, and cancer.

The study, published in Cell, identified a small molecule compound that restores physiological levels of telomerase reverse transcriptase (TERT), which normally is repressed with the onset of aging. Maintenance of TERT levels in aged lab models reduced cellular senescence and tissue inflammation, spurred new neuron formation with improved memory, and enhanced neuromuscular function, which increased strength and coordination.

The researchers show that TERT functions not only to extend telomeres, but also acts as a transcription factor to affect the expression of many genes directing neurogenesis, learning and memory, cellular senescence, and inflammation.

“Epigenetic repression of TERT plays a major role in the cellular decline seen at the onset of aging by regulating genes involved in learning, memory, muscle performance, and inflammation,” said corresponding author Ronald DePinho, M.D., professor of Cancer Biology. “By pharmacologically restoring youthful TERT levels, we reprogrammed expression of those genes, resulting in improved cognition and muscle performance while eliminating hallmarks linked to many age-related diseases.”

China appears to have installed a laser directed energy weapon on one of its Type 071 amphibious assault ships, mirroring U.S. and other nations’ expanding activities in the same arena. Recent actions against Houthi drones in the Red Sea have helped to spur further interest in fitting warships with directed energy weapons of various types, although most of China’s activities with laser weapons have, so far, been conducted on land.

A photo that recently appeared on social media shows an apparently newly installed laser weapon on a People’s Liberation Army Navy (PLAN) Type 071 amphibious transport dock, the vessel having reportedly just emerged from a refit. The system is mounted immediately aft of the 76mm dual-purpose gun on the ship’s bow. When not in use, the weapon is concealed under a relatively large dome-like cover.

The pursuit of a cure for Alzheimer’s disease is becoming an increasingly competitive and contentious quest with recent years witnessing several important controversies.

In July 2022, Science magazine reported that a key 2006 research paper, published in the prestigious journal Nature, which identified a subtype of brain protein called beta-amyloid as the cause of Alzheimer’s, may have been based on fabricated data.

One year earlier, in June 2021, the US Food and Drug Administration had approved aducanumab, an antibody-targeting beta-amyloid, as a treatment for Alzheimer’s, even though the data supporting its use were incomplete and contradictory.

Some physicians believe aducanumab never should have been approved, while others maintain it should be given a chance.

With millions of people needing an effective treatment, why are researchers still fumbling in this quest for a cure for what is arguably one of the most important diseases confronting humankind?

Researchers assessed many thousands of different molecules in people from age 25 to 75, as well as their microbiomes—the bacteria, viruses and fungi that live inside us and on our skin—and found that the abundance of most molecules and microbes do not shift in a gradual, chronological fashion. Rather, we undergo two periods of rapid change during our life span, averaging around age 44 and age 60. A paper describing these findings appears in Nature Aging.

“We’re not just changing gradually over time; there are some really dramatic changes,” said Michael Snyder, Ph.D., chair of genetics and the study’s senior author. “It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that’s true no matter what class of molecules you look at.”

Conventional aircraft wings follow design principles established by the Wright brothers and rely on Bernoulli’s principle. This dictates that faster airflow over the top of the wing results in lower pressure, while slower airflow underneath generates higher pressure, thus lifting the plane.

However, as an aircraft approaches the speed of sound, shock waves come into existence, creating turbulence and drag. These reduce lift and cause damaging vibrations.

The research team, led by Professor Gao Chao of the university’s School of Aeronautics, proposed that strategic holes in the wing could solve these ill effects.

They employed computer simulations and wind tunnel experiments, which demonstrated that the holes in the wing disrupted shock waves and mitigated the ensuing vibrations. Remarkably, they also discovered a boost of over 10% in aerodynamic efficiency.

Scientists looking to tackle our ongoing obesity crisis have made an important discovery: Intermittent calorie restriction leads to significant changes both in the gut and the brain, which may open up new options for maintaining a healthy weight.

Researchers from China studied 25 volunteers classed as obese over a period of 62 days, during which they took part in an intermittent energy restriction (IER) program – a regime that involves careful control of calorie intake and relative fasting on some days.

Not only did the participants in the study lose weight – 7.6 kilograms (16.8 pounds) or 7.8 percent of their body weight on average – there was also evidence of shifts in the activity of obesity-related regions of the brain, and in the make-up of gut bacteria.

Solving a decades-old problem, a multidisciplinary team of Caltech researchers has figured out a method to noninvasively and continually measure blood pressure anywhere on the body with next to no disruption to the patient. A device based on the new technique holds the promise to enable better vital-sign monitoring at home, in hospitals, and possibly even in remote locations where resources are limited.

The new patented technique, called resonance sonomanometry, uses sound waves to gently stimulate resonance in an artery and then uses ultrasound imaging to measure the artery’s resonance frequency, arriving at a true measurement of blood pressure. In a small clinical study, the device, which gives patients a gentle buzzing sensation on the skin, produced results akin to those obtained using the standard-of-care blood pressure cuff.

Venezuelan President Nicolás Maduro’s disputed election victory spells trouble for Vice President Kamala Harris as the U.S.-Mexico border takes center stage in the race for the presidency.

The presumptive Democratic nominee in the 2024 presidential race faces difficult paths to navigate after Maduro was declared the winner on Sunday, most importantly because the result may lead to what one expert told Newsweek said was likely to be a surge in migration from Venezuelans fleeing his regime.

If that happens, Republican lawmakers who have branded Harris as Biden’s “border czar”—a description seen by her supporters as inaccurate—may attempt to capitalize on her comments about Venezuela to further attack her record on immigration policy and border security, particularly as migrant numbers typically rise between August and October.

Other aspects of the Biden-Harris administration’s policy toward Venezuela, which was an important oil supplier to the U.S. prior to sanctions as well as a source for rare earth elements crucial for emerging technologies, may also come under scrutiny.

Various elements of the Biden-Harris administration’s policies in foreign affairs are likely going to come back to bite Jambalaya right square on the ass–and rightly so.

The search is on worldwide to find ways to extract carbon dioxide from the air or from power plant exhaust and then make it into something useful. One of the more promising ideas is to make it into a stable fuel that can replace fossil fuels in some applications. But most such conversion processes have had problems with low carbon efficiency, or they produce fuels that can be hard to handle, toxic, or flammable.

Now, researchers at MIT and Harvard University have developed an efficient process that can convert carbon dioxide into formate, a liquid or solid material that can be used like hydrogen or methanol to power a fuel cell and generate electricity. Potassium or sodium formate, already produced at industrial scales and commonly used as a de-icer for roads and sidewalks, is nontoxic, nonflammable, easy to store and transport, and can remain stable in ordinary steel tanks to be used months, or even years, after its production.
