The proliferation of all things digital doesn’t mean that printing technology is no longer relevant. In fact, printing technology is required to make the semiconductors necessary for the digital world. And as an Osaka Metropolitan University-led team has shown using a new printing technique, printable magnetic devices for high-density data storage might soon be realized.

Dr. Ken-ichi Yuyama, a lecturer at the Graduate School of Science, and his colleagues report in APL Materials on the development of a new type of laser-induced forward transfer (LIFT) for laser printing using an optical vortex, which has been dubbed OV-LIFT.

The team shined a laser beam on a spatial light modulator and through a quarter-wave plate to convert the beam into a circularly polarized optical vortex. This beam was then focused onto a plate with magnetic ferrite nanoparticles that were shown to successfully be printed on a surface at high precision. The resulting printed crystals also have helix-like twisted structures, the direction of which could be controlled by changing the optical vortex’s helicity to the opposite rotation.

“The results of this research have the potential to be used not only for fine particle patterning but also for single crystal synthesis, which can be expected to lead to the development of new materials,” declared Dr. Yuyama. “We plan to apply this technology to various types of fine particles, as well as to shine a light on the formation mechanism and function of twisted crystals.”

Early onset dementia more common than previously reported – the incidence of Alzheimer’s disease seems to be on the rise

2024-07-25
A new major study by the University of Eastern Finland, the University of Oulu and Neurocenter Finland explored early-onset dementia in the working-age population in Finland. The study cohort was one of the largest in the world to date, and the findings were published on 24th of July 2024 in Neurology®, the medical journal of the American Academy of Neurology. Current epidemiological data on early-onset dementia is scarce and based on small study cohorts, with no recent data from Finland available. For the present ...

Pesticides potentially as bad as smoking for increased risk in certain cancers

2024-07-25
In modern day agriculture, pesticides are essential to ensure high enough crop yields and food security. These chemicals, however, can adversely affect plant and animal life as well as the people exposed to them. Now, in a population-based, nation-wide study, researchers in the US have put increased cancer risk through agricultural pesticide use into context with smoking, a better understood cancer risk factor. The results were published in Frontiers in Cancer Control and Society. “In our study we found that for some cancers, the effect of agricultural pesticide usage is comparable in magnitude to the effect of smoking,” said the study’s ...

NUS researchers develop new battery-free technology to power electronic devices using ambient radiofrequency signals

2024-07-25
Ubiquitous wireless technologies like Wi-Fi, Bluetooth, and 5G rely on radio frequency (RF) signals to send and receive data. A new prototype of an energy harvesting module – developed by a team led by scientists from the National University of Singapore (NUS) – can now convert ambient or ‘waste’ RF signals into direct current (DC) voltage. This can be used to power small electronic devices without the use of batteries. RF energy harvesting technologies, such as this, is essential as they reduce battery dependency, extend device lifetimes, minimise environmental impact, and enhance the feasibility of wireless sensor networks and IoT devices in remote ...

New protein discovery may influence future cancer treatment

2024-07-25
Researchers from the University of Otago, Christchurch, have spearheaded the discovery of a protein function which has the potential to guide the development of novel cancer treatment options and improve the diagnosis of various cancers. The exciting research finding, carried out alongside Dr Vanessa Morris from the University of Canterbury’s School of Biological Sciences as well as researchers in Australia and Denmark, centres on the activity of a tumour- suppressing protein called p16. The discovery, published in the British scientific journal Nature Communications and first authored by ...

Timing matters: Scripps Research study shows ways to improve health alerts

Timing matters: Scripps Research study shows ways to improve health alerts
2024-07-25
LA JOLLA, CA—When seemingly healthy people receive an alert from a wearable sensor telling them they might have a respiratory virus—based on small changes in their unique heartrate, sleep and activity patterns—what do they do? According to a new study by Scripps Research scientists carried out at the height of the COVID-19 pandemic, only a quarter of people follow up such an alert with an at-home viral test. That is just one conclusion of the new study, published in The Lancet Digital Health on July 24, 2024, which tested the feasibility ...

Chemical analyses find hidden elements from renaissance astronomer Tycho Brahe’s alchemy laboratory

Chemical analyses find hidden elements from renaissance astronomer Tycho Brahe’s alchemy laboratory
2024-07-25
In the Middle Ages, alchemists were notoriously secretive and didn’t share their knowledge with others. Danish Tycho Brahe was no exception. Consequently, we don’t know precisely what he did in the alchemical laboratory located beneath his combined residence and observatory, Uraniborg, on the now Swedish island of Ven. Only a few of his alchemical recipes have survived, and today, there are very few remnants of his laboratory. Uraniborg was demolished after his death in 1601, and the building materials were scattered for reuse. However, during an excavation ...

Pacific Northwest launches clean hydrogen energy hub
2024-07-25
RICHLAND, Wash.—The Pacific Northwest is set to begin work building out a clean hydrogen economy with today’s announcement of a Phase 1 funding award from the Department of Energy. The $27.5 million award to the Pacific Northwest Hydrogen Association (PNWH2), a multi-state nonprofit organization, will be matched by industry partners up to $125 million in Phase 1 of the project. DOE’s Pacific Northwest National Laboratory will serve as an advisor to the PNWH2 by conducting life-cycle analysis to predict and understand the planned hydrogen energy infrastructure impact on decreasing emissions and aiding in community engagement.   Public ...

Tiny deletion in heart muscle protein briefly affects embryonic ventricles but has long-term effects on adult atrial fibrillation

Tiny deletion in heart muscle protein briefly affects embryonic ventricles but has long-term effects on adult atrial fibrillation
2024-07-25
BIRMINGHAM, Ala. – Millions of adults have atrial fibrillation — an irregular beating of the upper chambers of the heart that yields increased risk of heart failure, stroke and death. Many genetic mutations in the developing fetus can lead to adult atrial fibrillation, including mutations that shorten the massive protein titin in cardiac muscle cells. Now, in a study in zebrafish and human heart muscle cells, researchers show that a tiny deletion in the A-band of titin — the loss of just nine amino acids out of more than 27,000 to 35,000 amino acids of an intact titin protein — causes a developmental ...

Harms of prescribing NSAIDs to high risk groups estimated to cost NHS £31m over 10 years

2024-07-25
Prescribing non-steroidal anti-inflammatory drugs (NSAIDs) to people at high risk of harm from them is estimated to cost the NHS in England around £31 million and cause more than 6,000 lost years of good health over 10 years, finds a study published by The BMJ today. NSAIDs continue to be a source of avoidable harm and healthcare costs, and more needs to be done to address this, especially in high risk groups, say the researchers. NSAIDs are used for pain and inflammation and are one of the most widely prescribed groups of medicines in the world, But they are known to increase the risk of gastrointestinal bleeding, heart attacks, stroke, and kidney damage. Yet ...
