Researchers have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart's aortic valve and the surrounding structures that mimic the exact look and feel of a real patient.
A new study shows how two responses in separate locations inside plant cells work in concert to help corn plants respond to heat stress. The research was made possible by the Enviratron, an innovative plant sciences facility at Iowa State University that utilizes a robotic rover and highly controlled growth chambers.
'Jumping' sequences of DNA, known as transposable elements, partner up with evolutionarily recent proteins to influence the differentiation and physiological functioning of human neurons.
The anatomy of plant fossils including an enormous tree that grew 10 million years ago in the now arid, high-elevation Central Andean Plateau calls current paleoclimate models into question, suggesting that the area was more humid than models predict.
Small-scale poultry farmers in Vietnam tend to respond to viral outbreaks of highly pathogenic avian influenza (HPAI) by rapidly selling their birds as a way to avoid financial loss, according to a new study. As these birds are commingled with other birds in markets and trading networks, this practice may increase the likelihood of widespread disease transmission.
Infants from households reporting very low 'food security,' a measure of access to adequate and healthy meals, tend to weigh more than those from households with relatively high food security.
Researchers working with tungsten to armor the inside of future fusion reactors had some surprising results when looking at the probability of contamination.
A simple coffee and a quick catnap could be the cure for staying alert on the nightshift as new research shows that this unlikely combination can improve attention and reduce sleep inertia.
Climate change occurring shortly before their disappearance triggered a complex change in the behavior of late Neanderthals in Europe: they developed more complex tools, suggests new research.
Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body.
In a study carried out over more than two years, scientists were able to draw a new and surprisingly detailed picture of coastal cliff failure activity.
A study of a gateway receptor for SARS-CoV-2 may help explain the wide variety of symptoms and organs involved with SARS-CoV-2 infection and COVID-19. The results suggest that a multi-organ infection with SARS-CoV-2 may be via the angiotensin-converting enzyme 2 (ACE2) receptor, which is found almost everywhere throughout the body.
Researchers found that last-mile delivery networks will become more decentralized and the delivery speed of the drones will increase as the technology matures.
While speakers of English and other Western languages prefer using suffixes more than prefixes, a new study reveals that this preference is not as universal as once thought.
Breast milk strengthens a child's immune system, supporting the intestinal flora. These facts are common knowledge. But how does this work? What are the molecular mechanisms behind this phenomenon? And why is this not possible the same way with bottle feeding? The reasons were unknown until a team recently discovered the role of alarmins.
New biomaterials reduce the risk of infection and facilitate the body's healing processes. These nanostructured materials are based on spider silk proteins. They prevent colonization by bacteria and fungi, but at the same time proactively assist in the regeneration of human tissue. They could be used for implants, wound dressings, prostheses, contact lenses, and other everyday aids.
High-resolution ocean modelling has found the world's strongest ocean currents, which play key roles in fisheries and ocean ecosystems, will experience more intense marine heatwaves than the global average over the coming decades.
The northern quoll, one of Australia's most adorable and endangered native carnivores, appears to be adapted to dramatically different landscapes -- which may be key to the species' survival. A new study that found similarities between northern quoll skulls across a 5000 kilometer range, which has raised hopes scientists will be able to cross-breed isolated populations.
A surface displays structural colors when light is reflected by tiny, regular structural elements in a transparent material. Researchers have now developed a method to make structural colors from cellulose-based polymers by using coated droplets that exist in a surrounding fluid -- so-called liquid marbles. The system readily responds to environmental changes, which makes it interesting for...
Feelings of panic when a person is away from their smartphone could be connected to general feelings of inadequacy and inferiority, a new study of young people suggests.
A new study shows that the role of personality may vary depending on how physical activity is measured.
Understanding the skin damage caused by rubbing could lead to better topical skin treatments and help prevent the formation of new routes for viral and bacterial infection.
In order to kill diseased cells, our immune system must first identify them. The so-called peptide-loading complex plays a key role in this process. A research team has analyzed this nanomachine in atomic detail.
A stretchable, wearable gas sensor for environmental sensing has been developed and tested.
