Mechanism that helps immune cells to invade tissues

To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within. Scientists have now discovered how immune cells protect their sensitive insides as they squeeze between tissue cells. The team lays the foundation for identifying new targets in cancer treatment.

California mice eat monarch butterflies

At the largest winter monarch aggregation in central Mexico, scientists have observed that rodents attack monarchs that fall to the ground. Biologists have now discovered that the western harvest mouse also eats grounded monarchs. Documenting this new feeding behavior is a reminder of little we know about the interactions that may be lost as insect populations decline.

Novel way to perform ‘general inverse design’ with high accuracy

'Inverse design' is a design approach that reverses the traditional design process and enables the designer to discover and create materials that possess a user-defined set of properties. Researchers demonstrate a nascent machine learning-based solution that uses an algorithm to identify any material that exhibits specific properties or characteristics. Termed 'general inverse design,' the novel...

Microbes produce oxygen in the dark

It is common knowledge that there would be no oxygen on Earth were it not for sunlight; the key component in photosynthesis. Now researchers have made the surprising discovery that oxygen is also produced without sunlight, possibly deep below the ocean surface.

Mass production of revolutionary computer memory moves closer with ULTRARAM™ on silicon wafers for the first time

A pioneering type of patented computer memory known as ULTRARAM™ has been demonstrated on silicon wafers in what is a major step towards its large-scale manufacture. ULTRARAM™ is novel type of memory with extraordinary properties. It combines the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency and endurance of a working memory, like DRAM. To do this it...

Sending life to the stars

No longer solely in the realm of science fiction, the possibility of interstellar travel has appeared, tantalizingly, on the horizon. Although we may not see it in our lifetimes -- at least not some real version of the fictional warp-speeding, hyperdriving, space-folding sort -- we are having early conversations of how life could escape the tether of our solar system, using technology that is...

'Simple' bacteria found to organize in elaborate patterns

Researchers have discovered that biofilms, bacterial communities found throughout the living world, are far more advanced than previously believed. Scientists found that biofilm cells are organized in elaborate patterns, a feature that previously only had been associated with higher-level organisms such as plants and animals.

Fingerprint patterns are linked to limb development genes

In the most comprehensive analysis to date, researchers found that the shapes of fingerprints -- whether they are circular, wavy, or winding -- are influenced by the genes responsible for limb development instead of skin patterning. The study could help scientists better understand the association between genes and phenotypical traits in humans.

Zoo air contains enough DNA to identify the animals inside

The air in a zoo is full of smells, from the fish used for feed to the manure from the grazing herbivores, but now we know it is also full of DNA from the animals living there. Two research groups have each published an independent proof-of-concept study showing that by sampling air from a local zoo, they can collect enough DNA to identify the animals nearby. This may prove to be a valuable,...

Can a human microglial atlas guide brain disorder research?

Researchers analyzed thousands of microglia from different brain regions of deceased patients who had been diagnosed with a variety of neuropsychiatric and neurodegenerative disorders. Their results support the idea that microglia may play critical roles in some cases of brain disease while also providing a potentially valuable guide for future studies.

Unexpected hope for millions as bleached coral reefs continue to supply nutritious seafood

Coral reef ecosystems support diverse small-scale fisheries -- and the fish they catch are rich in micronutrients vital to the health of millions of people in the tropics, a new study reveals. And, counter-intuitively, following bleaching events that kill off coral and can transform the composition of reef ecosystems, reef fisheries can remain rich sources of micronutrients, even increasing in...
