Researchers engineer electrically tunable graphene devices to study rare physics
Scientists have developed a tunable graphene-based platform that allows for fine control over the interaction between light and matter in the terahertz (THz) spectrum to reveal rare phenomena known as exceptional points. The work could advance optoelec…
An immune ‘fingerprint’ reveals path for better treatment of autoimmune diseases
Most autoimmune diseases are easy to diagnose but hard to treat. A new article proposes using your unique immune cell fingerprint to rapidly identify which treatments will work for your autoimmune disease.
Nano particle trapped between mirrors works as a quantum sensor
Sensors are a pillar of the Internet of Things, providing the data to control all sorts of objects. Here, precision is essential, and this is where quantum technologies could make a difference. Researchers are now demonstrating how nanoparticles in tin…
Blockchain offers a solution to post-Brexit border digitization to build supply chain trust, research shows
As a result of the UK leaving the European Union, logistics firms have faced additional friction at UK borders. Consequently, there have been calls for automated digital borders, but few such systems exist. Researchers have now discovered that a blockc…
How to keep knowledge alive for emergencies
Researchers have investigated how to prevent knowledge and skills that were learned long ago and are rarely used from getting rusty.
Cell biology: How mitochondria report stress
Researchers have discovered the mechanism by which the protein DELE1 detects organelle stress. This offers a possible new approach for treating neurodegenerative diseases.
Two DNA defense systems behind resilience of 7th cholera pandemic
Two DNA defense systems protect the bacterial strains responsible for the ongoing seventh cholera pandemic from potentially harmful genetic material and viruses, scientists have found. Their study also shows that the defense systems may have been key i…
The role of genes in prenatal responses to air pollution
Exposure to pollution during pregnancy can have many adverse effects in infants and children that can even extend into adulthood. For example, air pollution exposure is associated with increased risk of low birth weight, preterm birth and risk for deve…
High-ranking naked mole-rats are more resilient
Naked mole-rats are full of surprises. The latest is that higher-ranked mole-rats most likely have an immunological advantage over animals with lower social status.
Scientists unveil the format of working memory
A team of scientists has discovered how working memory is ‘formatted’ — a finding that enhances our understanding of how visual memories are stored.
Evidence in mice that bacteria in tumors help cancer cells metastasize
Bacteria promote cancer metastasis by bolstering the strength of host cells against mechanical stress in the bloodstream, promoting cell survival during tumor progression, researchers report.
AI predicts if — and when — someone will have cardiac arrest
A new artificial intelligence-based approach can predict, significantly more accurately than a doctor, if and when a patient could die of cardiac arrest. The technology, built on raw images of patient’s diseased hearts and patient backgrounds, stands t…
New evidence suggests California’s environmental policies preferentially protect whites
Asian and Hispanic communities experience significantly more air pollution from economic activity compared to predominantly white neighborhoods across the state of California, according to new research.
New hope for predicting and treating heart failure in babies born with deadly heart defect
Almost one third of babies born with hypoplastic left heart syndrome, or HLHS, die from heart failure before their first birthday. By uncovering cellular processes that drive heart failure in these young patients, a new study may hold the answers to id…
Turbulence from spawning fish keeps a healthy circulation in coastal waters
A new study has shown how fish influence ocean ecosystems in coastal regions, revealing for the first time how they circulate nutrients and oxygen around the waters when they spawn. This process is key to keeping the ecosystems running.
Private protected areas help conserve overlooked and threatened regions
New research shows that private protected areas help conserve underrepresented biomes and highly threatened regions. Researchers have assessed 17,561 privately protected areas in 15 countries across five continents. Their findings reveal that compared …
COVID-19 alters levels of fertility-related proteins in men, study suggests
Increasing evidence suggests that the COVID-19 virus can also impair fertility. Now, researchers have analyzed protein levels in semen of men who have recovered from COVID-19. The pilot study suggests that even mild or moderate illness could change the…
Engineers describe how fluid suspensions exhibit different behaviors at different scales
Honey is already a pretty thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs throughout the natural and constructed world: From mudflo…
Ocean water samples yield treasure trove of RNA virus data
Ocean water samples collected around the world have yielded a treasure trove of new data about RNA viruses, expanding ecological research possibilities and reshaping our understanding of how these small but significant submicroscopic particles evolved.
