TEL AVIV...January 29, 2020 - BGN Technologies, the technology-transfer company of Ben-Gurion University of the Negev (BGU), Israel, is introducing the first all-optical "stealth" encryption technology that will be significantly more secure and private for highly sensitive cloud-computing and data center network transmission.
The new all-optical encryption innovation will be introduced at the Cybertech Global Tel Aviv conference taking place January 28-30, 2020 in Tel Aviv, Israel.
Imagine having your curtains extended or retracted automatically without needing to lift a finger?
Reversible 4D printing technology could make these 'smart curtains' a reality without the use of any sensors or electrical devices, and instead rely on the changing levels of heat during the different times of the day to change its shape.
Tidewater glaciers, the massive rivers of ice that end in the ocean, may be melting underwater much faster than previously thought, according to a Rutgers co-authored study that used robotic kayaks.
The findings, which challenge current frameworks for analyzing ocean-glacier interactions, have implications for the rest of the world's tidewater glaciers, whose rapid retreat is contributing to sea-level rise.
Tomorrow's electronics are getting ever smaller. Researchers are thus searching for tiny components that function reliably in increasingly narrow configurations. Promising elements include the chemical compounds indium selenide (InSe) and gallium selenide (GaSe). In the form of ultra-thin layers, they form two-dimensional (2D) semi-conductors. But, so far, they have hardly been used because they degrade when they get in contact with air during manufacturing. Now, a new technique allows the sensitive material to be integrated in electronic components without losing its desired properties.
Stress is prevalent in modern society and can affect human health through its effects on appetite. However, knowledge about the neural mechanisms related to the alteration of the subjective level of appetite caused by acute stress in humans remains limited. We focused on the effects of stress caused by expecting critical personal events such as school examinations and public speaking engagements on appetite and aimed to clarify the neural mechanisms by which acute stress affects appetite in healthy, non-obese males during fasting.
Until now, scientists assumed that most plants suffer from water stress during droughts: they close their stomata to retain water, stop growing and, in the worst case, wither. As a result, there is a decrease in evaporation and transpiration of water from vegetation, soil and water surfaces - a process that experts call evapotranspiration. "But despite dry and warm conditions, droughts are not occurring at higher altitudes in, say, forested mountain areas," says Simone Fatichi, senior assistant at the ETH Zurich Institute of Environmental Engineering.
British newspapers are routinely glamorising combat by creating a moral separation between combat and non-combat injuries, according to new research published in the journal Media, War and Conflict.
Academics from Anglia Ruskin University's Veterans and Families Institute for Military Social Research (VFI) examined the reporting of injuries sustained by British military personnel during the height of the UK's war in Afghanistan in 2009, and a comparison period in 2014, in all daily and Sunday UK national newspapers.
A group of materials scientists at Tokyo Institute of Technology has shown that a palladium-based intermetallic electride, Y3Pd2, can improve the efficiency of carbon-carbon cross-coupling reactions. Their findings point the way to a more sustainable world through catalysis.
New research from Kyushu University in Japan could one day help provide humans living away from Earth some of the nutrients they need to survive in space or even give clues to how life started.
Researchers at the International Institute for Carbon-Neutral Energy Research reported a new process using electricity to drive the efficient synthesis of amino acids, opening the door for simpler and less-resource-intensive production of these key components for life.
Published in Psychological Medicine, the research used fMRI scans to examine the brain activity of 13 people with a diagnosis of psychosis under the influence of a single dose of CBD or placebo and 16 controls whilst they were undertaking a memory task. The researchers showed that, during the task, there was a different pattern of activity in the prefrontal and mediotemporal brain areas of people with psychosis under placebo compared to the activity seen in those without psychosis.
A study conducted out of The University of Georgia delved into the comparative yields of sweet pepper varieties produced under organic farming conditions.
George Boyhan, Cecilia McGregor, Suzanne O'Connell, Johannah Biang, and David Berle completed a replicated, randomized experiment involving 13 pepper varieties produced on land managed organically for the 6 previous years.
An international research team which includes specialists from ITMO University has conducted a series of experiments with the goal of studying the immune system and identifying the genes and proteins involved in the response to certain harmful bacteria. The scientists found that "turning off" a gene responsible for the production of the protein Beclin 1, or the gene that produces the FIP200 protein, resulted in the test animals becoming nearly completely immune to the infectious disease listeriosis.
AUSTIN, Texas -- A multidisciplinary team of engineers and scientists has developed a new class of filtration membranes for a variety of applications, from water purification to small-molecule separations to contaminant-removal processes, that are faster to produce and higher performing than current technology. This could reduce energy consumption, operational costs and production time in industrial separations.
When chemists or engineers want to make a new type of material, they head to the laboratory and start "cooking." Much like trying to improve upon a food recipe, the process involves trying new chemical ingredients or adjusting cooking times and temperatures. But what if instead of relying on a time-consuming process without guarantees of success, scientists could simply "snap" different chemical "pieces" together to make something new?
OAK BROOK, Ill. - The presence of a blood clot on the wall of the aorta in people with abdominal aortic aneurysms is associated with more rapid, potentially dangerous growth in the aneurysm, according to a major study published in the journal Radiology. Researchers said the findings could help identify which patients need more aggressive treatment and more frequent follow-up imaging after their initial diagnosis.
