Researchers have identified more than 250 'severity associated' proteins in the worst cases of COVID-19. These findings could help researchers identify the mechanisms that cause severe COVID-19.
Researchers have found that people who live beyond 105 years tend to have a unique genetic background that makes their bodies more efficient at repairing DNA, according to a new study.
Researchers have developed a breakthrough in energy-efficient phototransistors. Such devices could eventually help computers process visual information more like the human brain and be used as sensors in things like self-driving vehicles.
Studying protein changes in the kidneys as we age, as well as the transcription of genes into proteins, helps provide a full picture of the age-related processes that take place in these organs.
Scientists have revealed how an antibiotic of 'last resort' kills bacteria.
Researchers have identified an enzyme that may help to curb chronic kidney disease, which affects approximately 700 million people worldwide.
Scientists have developed algorithms that more efficiently measure how difficult it would be for an attacker to guess secret keys for cryptographic systems. The approach could reduce the computational complexity needed to validate encryption security.
New research has found that by eating just one cup of nitrate-rich vegetables each day people can significantly reduce their risk of heart disease.
Researchers have identified a set of genes, called clock genes, that control circadian rhythms. But a more complicated gene network than previously known appears related to these rhythms. Scientists detail a statistical model they are using to help identify the genes involved in this network. With help from other disciplines, they hope to fully understand how these genes work together to make...
If a respiratory droplet from a person infected with COVID-19 lands on a surface, it becomes a possible source of disease spread, because while 99.9 percent of the droplet's liquid content evaporates within minutes, a residual thin film that allows the virus to survive can be left behind. In a new study, researchers explore how the evaporation rate of residual thin films can be accelerated by...
Researchers identify a key area in the cortex that appears to be the gate of conscious awareness.
A meta-analysis of 14 air pollution studies from around the world found that exposure to high levels of air pollutants during childhood increases the likelihood of high blood pressure in children and adolescents, and the risk of hypertension later in life.
There has been an increase in the number of people over 65 who have needed spinal fusion surgery, and many have focused on trying to create a biomimetic scaffold that induces vascularization. Researchers present a solution to address the challenge: They designed a microchannel scaffold made of a collagen and hydroxyapitite combination, with each strut consisting of micrometer-scaled microchannels....
Scientists have developed an extension to an ordinary cellphone that makes it capable of detecting chemicals, drugs, biological molecules, and pathogens. The development is based on fluorescence spectroscopy and Raman spectroscopy and uses the high-quality cameras found in modern cellphones. An inexpensive diode laser is used as a light source, oriented at right angles to the line connecting the...
Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they've been extremely difficult to detect -- until now. Using what they describe as a 'chemical nose,' chemists are able to 'smell' when bits of DNA are folded in unusual ways.
Astronomers have identified more than 4,000, and counting, confirmed exoplanets -- planets orbiting stars other than the sun -- but only a fraction have the potential to sustain life. Now, new research is using the geology of early planet formation to help identify those that may be capable of supporting life.
Researchers are looking into a possible future in which doctors can hit a button to print out a scaffold on their 3-D printers and create custom-made replacement skin, cartilage, or other tissue for their patients.
Researchers have demonstrated how two interfering photons can bunch into various shapes. These complex shapes are beneficial for quantum technologies, such as performing fast photonic quantum computations and safe data transfer. The method opens new possibilities also for creating enhanced measurement and sensing techniques.
Sea turtles in the Cayman Islands are recovering from the brink of local extinction, new research shows.
In 2019 the climate movement experienced an unprecedented growth in its mobilization capacity and its political and media impact. The success of the movement is closely linked to the figure of Greta Thunberg and the global impact of her discourse and the 'Fridays for Future' movement in hundreds of cities around the world.
Microplastics do not just end up in the open sea - in fact, a lot also end up in the ecosystems of the coastal zones, a new study shows and this may threaten wildlife.
Artificial intelligence that enhances remote monitoring of water bodies - highlighting quality shifts due to climate change or pollution - has been developed.
A team of researchers have identified a genetic mutation associated with exfoliation syndrome, characterized by abnormal protein material accumulating in the front of the eye. It is the most common cause of glaucoma, and a major cause of irreversible blindness. The findings could lead to further research on the causes of the systemic disorder and potential cures.
Cancerous tumors thrive on blood, extending their roots deep into the fabric of the tissue of their host. They alter the genetics of surrounding cells and evolve to avoid the protective attacks of immune cells. Now, researchers have developed a way to study the relationship between solid, difficult-to-treat tumors and the microenvironment they create to support their growth.
New research into octopus vision has led to a quick and easy test that helps optometrists identify people who are at greater risk of macular degeneration, the leading cause of incurable sight loss.
