Fixating on whether the planet’s surface has warmed by more than 1.5 degrees C can lead us astray, Prof. Raghu Murtugudde writes
Scientists hope to advance precision medicine through the discovery of a gene variant that leads to the same phenotype in separate high-dwelling populations while taking a different evolutionary path.
A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for Alzheimer's. Scientists now theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors.
Snail shells are often colorful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed. Residues of ancient color patterns are therefore very rare. This makes a new discovery all the more astonishing: researchers found pigments in twelve-million-year-old fossilized snail shells.
Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers investigated the bond that builds between the electrons and holes contained in these materials. By using a special method to break up the bond between electrons and holes, they were able to gain a microscopic insight into charge transfer processes across a semiconductor interface.
A small ultrasound sticker, worn on the skin, can monitor the stiffness of organs deep inside the body. The sensor could detect signs of disease such as liver and kidney failure, and the progression of solid tumors.
A research team has picked a side in the 'Snowball Earth' debate over the possible cause of planet-wide deep freeze events that occurred in the distant past. According to a new study, these so-called 'Snowball' Earth periods, in which the planet's surface was covered in ice for thousands or even millions of years, could have been triggered abruptly by large asteroids that slammed into the Earth.
Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.
Immigrants living with dementia were more likely to present with agitation and aggression compared with their non-immigrant counterparts, a new study has found.
Engineers have created a more efficient way of converting carbon dioxide into valuable products while simultaneously addressing climate change.
Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel.
Researchers have captured time-lapse videos of stem cells dividing in growing plant roots. By watching how the cells divide in response to certain chemical signals over time, the team is uncovering new clues to how stem cells choose one developmental path over another.
In an effort five years in the making, researchers describe the interplay between fats and proteins in brain cells and how their dysfunction contributes to the development of late-onset Alzheimer's disease.
A coating that can hide objects in plain sight, or an implant that behaves exactly like bone tissue: These extraordinary objects are already made from 'metamaterials'. Researchers have now developed an AI tool that not only can discover such extraordinary materials but also makes them fabrication-ready and durable. This makes it possible to create devices with unprecedented functionalities.
Beaked whales are among the least studied mammals in the world. Now, a new study reveals surprising information about the Baird's beaked whale species.
A research team has developed a tape that can be used to stick two-dimensional (2D) materials to many different surfaces, in an easy and user-friendly way. Their finding will aid research into and boost production of 2D materials for next-generation devices.
Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All these photocatalysts require high energy light for excitation and their oxidizing power has not yet been fully exploited. Furthermore, precious and hence expensive metals are the decisive ingredients in most cases. A team of researchers has now developed a new molecular system based on the element manganese. Manganese, as opposed to precious metals, is the third most abundant metal after iron and titanium and hence widely available and very cheap.
FuncOmap directly maps the functional states of oncoproteins in patients' tumour sections, so that clinicians can predict which treatments will work best.
A team of scientists has devised means for classical computing to mimic a quantum computing with far fewer resources than previously thought. The scientists' results show that classical computing can be reconfigured to perform faster and more accurate calculations than state-of-the-art quantum computers.
Wherever hot water flows, limescale is never far away. In households, this is a nuisance; in thermal power stations, it's an expensive problem. Now researchers have found an answer.
