The security of traditional attribute-based searchable encryption schemes relies on traditional number-theoretic assumptions, and thus they are not able to resist the threat of quantum algorithms. Meanwhile, existing lattice-based searchable encryption schemes have two main problems: one is the low efficiency of the execution of encryption, key generation and search algorithms. The second is the large space required for storing search trapdoors. To solve the problems, a research team led by Yang YANG published their new ...

The hot-end components of high-performance high-speed aircrafts need to meet performance requirements such as long service life, wide temperature range oxidation resistance and ablation resistance. This puts forward higher requirements for high-temperature service performance of thermal protection system (TPS). With low density, low expansion and excellent high temperature mechanical properties, carbon-carbon (C/C) composites are expected to be the best choice for the new generation of TPS. However, the oxidation sensitivity of C/C composites severely limits their service life in high-temperature ablation environment. It ...

Behavioral interventions are strategies designed to help people change their behaviors in a way that is positive for themselves and the community. These behaviors can relate to various topics, such as health, citizenship, ecology, and more. Interventions can be applied individually, like someone seeing a psychologist to quit smoking, or collectively, such as NGOs and public institutions investing in anti-smoking campaigns or raising awareness about the dangers of drunk driving. Understanding how to adapt behavioral interventions to different cultures is essential for the success of health ...

New class of cancer mutations discovered in so-called ‘junk’ DNA Using artificial intelligence, Garvan Institute researchers have found potential cancer drivers hidden in so-called ‘junk’ regions of DNA, opening up possibilities for a new approach to diagnosis and treatment. Non-coding DNA – the 98% of our genome that doesn’t contain instructions for making proteins – could hold the key to a new approach for diagnosing and treating cancers, according to a new study from the Garvan Institute of Medical Research. The findings, ...

Ever wondered why you performed worse than expected in that final university exam that you sat in a cavernous gymnasium or massive hall, despite countless hours, days and weeks of study? Now you have a genuine reason – high ceilings. New research from the University of South Australia and Deakin University has revealed a link between rooms with high ceilings and poorer examination results. A study published in the Journal of Environmental Psychology, led by architecture and psychology-trained UniSA researcher Dr Isabella Bower in collaboration with educational psychology researcher Associate Professor Jaclyn Broadbent from Deakin University, demonstrates that building design impacts ...

A world-first study has found low-dose aspirin may treat flu-induced blood vessel inflammation, creating better blood flow to the placenta during pregnancy.   Animal studies examined whether the treatment for preeclampsia could be applied to flu infections – and the results, according to the research team, were very promising.  Lead researcher and RMIT Post-Doctoral Research Fellow, Dr Stella Liong, said flu infections during pregnancy can resemble preeclampsia, a pregnancy complication that causes inflammation to the aorta and blood vessels.   Low-dose aspirin is commonly taken to prevent preeclampsia, as it stops the body from creating chemicals that cause ...

Osaka, Japan – Neuroendocrine tumors, including small cell lung cancer and neuroendocrine prostate cancer, are very aggressive with high chances of spreading. However, many individuals develop resistance to few available treatment options, leading to poor patient outcomes. Researchers are therefore aiming to develop new therapeutic methods that focus on the disease-specific molecular mechanisms of these tumors. In a recent article published in Molecular Therapy: Nucleic Acids, a team of researchers at Osaka University describe a strategy targeting one such mechanism, called RNA splicing. RNA splicing is the process ...

New research from the University of Utah demonstrates how wind-carried dust from the exposed bed of Great Salt Lake is disproportionately affecting disadvantaged communities in the Salt Lake metro area. The findings suggest restoring the lake to a healthy water level would reduce disparities in harmful dust exposure experienced by different racial/ethnic and socioeconomic groups, along with delivering other ecological and economic benefits.⁠ Exposure to particulate pollution arising from dry portions of the playa is highest among Pacific Islanders and Hispanics and lowest among white people compared to other racial/ethnic ...

Everyday clothing may soon be able to capture and record body movements according to new research published by the Universities of Bristol and Bath. Harmless low voltages are passed through conductive threads which are stitched into garment seams to create electrical circuits. Their resistance changes with the movement of the wearer's body. The work opens up new possibilities to make digital clothing which senses and captures movements much more accurately than is possible using current phones and smart watches. The paper, presented at the Designing Interactive Systems (DIS) conference in Copenhagen ...

SRI today announced that researchers are developing a new treatment that aims to provide a better option to fight malaria, particularly for people in low-income and rural regions. Researchers in SRI’s Pharmaceutical Sciences Lab are working on an affordable, shelf-stable anti-malarial drug formulation that could provide months of protection against the mosquito-borne disease with just a single injection, which means that individuals would no longer have to worry about missing a dose. Additionally, it has a low propensity for resistance and can be ...

In a recent study, researchers at Johns Hopkins Medicine suggest the cell’s messenger RNA (mRNA) — the major translator and regulator of genetic material — along with a critical protein called ZAK, spur the cell’s initial response to UV radiation damage and play a critical role in whether the cell lives or dies. While UV radiation has long been known to damage DNA, it also damages mRNA, and the latest findings, published June 5 in Cell, indicate that mRNAs act as first responders in telling the cells how to manage the stress. “RNA is a canary in the coal mine. It’s telling the cell, ‘We’ve got major damage here and ...

WASHINGTON — Researchers have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing process less expensive, helping it find wider use in a variety of applications. Two-photon polymerization is an advanced additive manufacturing technique that traditionally uses femtosecond lasers to polymerize materials in a precise, 3D manner. Although this process works well for making high-resolution microstructures, it isn’t widely used in manufacturing ...

LA JOLLA, CA and NEW YORK, NY—A major challenge in developing a vaccine for HIV is that the virus mutates fast—very fast. Although a person initially becomes infected with one or a few HIV strains, the virus replicates and mutates quickly, resulting in a “swarm” of viral strains existing in a single body. But scientists at Scripps Research; IAVI; the Ragon Institute of Mass General, MIT, and Harvard; La Jolla Institute for Immunology; and additional institutions have conducted a series of preclinical ...

Electrons have an intrinsic angular momentum, the so-called spin, which means that they can align themselves along a magnetic field, much like a compass needle. In addition to the electric charge of electrons, which determines their behaviour in electronic circuits, their spin is increasingly used for storing and processing data. Already now, one can buy MRAM memory elements (magnetic random access memories), in which information is stored in very small but still classical magnets – that is, ...

Already at the beginning of the COVID-19 pandemic, a group of Brazilian researchers pioneered in showing why SARS-CoV-2 infection tends to be more severe in diabetic patients. Now, the same team based at the Institute of Biology of the State University of Campinas (IB-UNICAMP) has discovered one of the reasons why obese people who do not have diabetes or even insulin resistance also have an increased risk of developing the severe form of the disease.  “New experiments show that the molecular mechanisms are quite different in the two cases,” Pedro Moraes-Vieira, a professor at IB-UNICAMP, who is coordinating ...

Getting individuals to act in the best interest of society can be a tricky balancing act, one that often walks a fine line between trying to convince people to act of their own volition, versus passing laws and regulations that make these actions compulsory.  In a new paper, published in the journal PNAS Nexus, SFI External Professor Stefani Crabtree (Utah State University) and Science Board Fellow Simon Levin (Princeton University), together with Colin Wren (University of Colorado, Colorado Springs) and Avinash ...

“If there was any doubt, this discovery demonstrates that genomics, extensively deployed over the past two decades, still has much to reveal to us.” BUFFALO, NY- July 2, 2024 – A new editorial paper was published in Oncotarget's Volume 15 on June 20, 2024, entitled, “Genomics has more to reveal.” In this new editorial, researchers Laurène Fenwarth and Nicolas Duployez from the University of Lille and CHU Lille discuss molecular and cytogenetic analyses that are now used to identify mutations and structural variants defining distinct subtypes of acute myeloid leukemias (AML) ...

The incidence of low birth weight rose sharply in India amid the COVID-19 pandemic, according to new research from the University of Notre Dame. Globally, 1 in 4 newborns has a low birth weight (less than 5.5 pounds), and the problem disproportionately affects low- and middle-income countries — particularly in South Asia, home to approximately one-fourth of the world’s population. Santosh Kumar, associate professor of development and global health economics at Notre Dame’s Keough School of Global Affairs, co-authored the study published in Communications Medicine, a Nature series journal. “This research shows that low birth weight became more common in India ...
