The European Southern Observatory (ESO) has released a stunning image snapped by the FOcal Reducer and low dispersion Spectrograph (FORS) instrument on ESO’s Very Large Telescope of Gum 26, an emission nebula located some 20,000 light-years away in the southern constellation of Vela. Emission nebulae are glowing clouds of ionized hydrogen gas that, as the [...]
Researchers tested approximately 4,518 drug compounds on 578 human cancer cell lines and found nearly 50 that have previously unrecognized anti-cancer activity. These drugs have been used to treat conditions such as diabetes, inflammation, alcoholism, and even arthritis in dogs. The findings suggest a possible way to accelerate the development of new cancer drugs or repurpose existing drugs to treat cancer.
Japanese cultural art of 'gyotaku,' which means 'fish impression' or 'fish rubbing,' captures accurate images of fish specimens. It has been used by recreational fishermen and artists since the Edo Period. Distributional data from 261 'Gyotaku' rubbings were extracted for 218 individual specimens, roughly representing regional fish fauna and common fishing targets in Japan through the years.
Children born to mothers who both drank and smoked beyond the first trimester of pregnancy have a 12-fold increased risk for Sudden Infant Death Syndrome (SIDS) compared to those unexposed or only exposed in the first trimester of pregnancy, according to a new study.
Scientists have shown how to combine the forecasts of a collection of suboptimal 'delay embedding' predictors for time series data. This work may help improve the forecasting of floods, stock market gyrations, spatio-temporal brain dynamics, and ecological resource fluctuations.
In a series of experiments, a duo of researchers from the Department of Zoology at Stockholm University has observed eight-week-old wolf puppies spontaneously responding to social-communicative behaviors from an unfamiliar person by retrieving a ball. These observations come as a surprise because it had been hypothesized that the cognitive abilities necessary to understand cues given [...]
Despite having proven effective at reducing wildfire risks, prescribed burns have been stymied by perceived and real risks, regulations and resource shortages. A new analysis highlights ways of overcoming those barriers, offering solutions for wildfire-ravaged landscapes.
River flow is reduced in areas where forests have been planted and does not recover over time, a new study has shown. Rivers in some regions can completely disappear within a decade. This highlights the need to consider the impact on regional water availability, as well as the wider climate benefit, of tree-planting plans.
The exceptionally preserved fossils of the oldest species of scorpion ever found have been unearthed in Wisconsin, the United States. The newly-discovered ancient scorpion lived around 437 million years ago during the early Silurian period. Dubbed Parioscorpio venator, the animal was about 2.5 cm (one inch) long - about the same size as many extant [...]
An international team of researchers has discovered a new species of titi monkey living in the forests of Brazil. Titi monkeys are one of the most diverse Neotropical primate groups, with over 30 species currently recognized. These tree-dwelling monkeys are small, between 23 and 46 cm (9-18 inches) tall. They have long, soft fur and [...]
The NASA/ESA Hubble Space Telescope has imaged a beautiful spiral galaxy called NGC 1022. NGC 1022 was discovered by the German-born British astronomer William Herschel on September 10, 1785. The galaxy is located some 62 million light-years away in the constellation Cetus. Also known as LEDA 10010 or IRAS 02360-0653, NGC 1022 is officially classified [...]
Engineers have devised a model that can predict the early mechanical behaviors and origins of an earthquake in multiple types of rock. The model provides new insights into unobservable phenomena that take place miles beneath the Earth's surface under incredible pressures and temperatures, and could help researchers better predict earthquakes -- or even, at least theoretically, attempt to stop them.
A study tracing acoustic communication across the tree of life of land-living vertebrates reveals that the ability to vocalize goes back hundreds of millions of years, is associated with a nocturnal lifestyle and has remained stable. Surprisingly, acoustic communication does not seem to drive the formation of new species across vertebrates.
Pet dogs are highly receptive to commands from their owners. But is this due to their training or do dogs have an innate ability to understand human signals? A new study finds that 80% of untrained stray dogs successfully followed pointing directions from people to a specific location. The results suggest that dogs can understand and respond to complex gestures without any training, meaning that dogs may have an innate connection to human behaviors.
Using DNA, smallest silica particles, and carbon nanotubes, researchers developed novel programmable materials. These nanocomposites can be tailored to various applications and programmed to degrade quickly and gently. For medical applications, they can create environments in which human stem cells can settle down and develop further. Additionally, they are suited for the setup of biohybrid systems to produce power, for instance.
Researchers have developed an original approach to flight scheduling that, if implemented, could result in a significant increase in profits for airlines and more flights that align with passengers' preferences.
