Viruses, including the coronavirus that causes COVID-19, can get passed from person to person via contaminated surfaces. But can some surfaces reduce the risk of this type of transmission without the help of household disinfectants? Wood has natural antiviral properties that can reduce the time viruses persist on its surface -- and some species of wood are more effective than others at reducing infectivity. Read more ›

Gravitational changes experienced by astronauts during space travel can cause fluids within the body to shift. This can cause changes to the cardiovascular system, including vessels in and around the eyes. These fluid shifts may be related to a phenomenon known as Spaceflight Associated Neuro-ocular Syndrome (SANS), which can cause astronauts to experience changes in eye shape and other ocular symptoms.

An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and... Read more ›

Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil. Read more ›

Measuring the heart rate of great apes in captivity is essential for both health management and animal studies. However, existing most methods are either invasive or inaccurate. Now, researchers have investigated the potential of using millimeter-wave radar technology to estimate heart rate from subtle body movements in chimpanzees. Their efforts will hopefully pave the way to better practices and techniques for monitoring heart rates in wild and captive primates. Read more ›

Looking under the microscope, a group of cells slowly moves forward in a line, like a train on the tracks. The cells navigate through complex environments. A new approach now shows how they do this and how they interact with each other. Read more ›

When low doses of cancer drugs are administered continuously near malignant brain tumors using so-called iontronic technology, cancer cell growth drastically decreases. Researchers demonstrated this in experiments with bird embryos. The results are one step closer to new types of effective treatments for severe cancer forms. Read more ›

Women diagnosed with perinatal depression are more likely to develop cardiovascular disease in the following 20 years compared to women who have given birth without experiencing perinatal depression. The study is the first of its kind to look at cardiovascular health after perinatal depression and included data on around 600,000 women. It found the strongest links with risks of high blood pressure, ischemic heart disease and heart failure. Read more ›

Autoimmune diseases cannot currently be cured, only treated, and this is also true for neuromyelitis optica spectrum disorder, which affects the central nervous system. A study of how the treatment acts on the immune system shows that it shifts the balance of types of immune cells. This finding may represent a step toward the development of personalized medicine for autoimmune diseases. Read more ›

Tuberculosis is a serious health threat, and the efficacy of the BCG vaccine against tuberculosis diminishes in adulthood, making booster vaccines a realistic option. Mycobacterial DNA-binding protein 1 (MDP1), a protein found in Mycobacterium tuberculosis, elicits higher protective IFN-gamma responses in individuals who suppress tuberculosis, thus making it a vaccine candidate.

An innovative synthesis strategy opened up the way to 2D/3D fused frameworks using inexpensive quinolines as feedstock, report scientists. By leveraging a light-sensitive borate intermediate, the scientists could transform quinoline derivatives into a great variety of 2D/3D fused frameworks in a straightforward and cost-effective manner. Their findings are expected to enable the synthesis of highly customizable drug candidates. Read more ›

A team has invented a technique to study electrochemical processes at the atomic level with unprecedented resolution. They have already used it to discover a surprising phenomena in a popular catalyst material and plan to apply their technology to studying a wide variety of electrochemical systems including batteries, fuel cells, and solar fuel generators. The insights could lead to more efficient and durable devices. Read more ›

Scientists have achieved a significant research milestone in the field of spinal cord injuries -- mapping out the cellular and molecular dynamics of paralysis in unprecedented detail with their open-source project 'Tabulae Paralytica'. Gr goire Courtine and his team have integrated cutting-edge cell and molecular mapping technologies with artificial intelligence to chart the complex molecular processes that unfold in each cell after spinal cord injuries (SCI). This seminal work not... Read more ›

Researchers describe how odors are encoded in the antennal lobe, the olfactory center in the brain of migratory locusts. Using transgenic locusts and imaging techniques, the researchers were able to show a ring-shaped representation of odors in the brain. The pattern of olfactory coding in the antennal lobe is the same at all stages of locust development. A better understanding of olfactory coding in the locust brain should help to... Read more ›
