Realistic portraits of squishy layer that’s key to battery performance
- ScienceDaily
- 22/1/6 20:37
Scientists have made realistic close-ups of a plump, squishy layer called the solid-electrolyte interphase (SEI) that forms on lithium metal anodes as a result of chemical reactions with the electrolyte. Knowing what it really looks will give them a new way to improve next-gen battery design.
Mechanism that helps immune cells to invade tissues
- ScienceDaily
- 22/1/6 20:37
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
- ScienceDaily
- 22/1/6 20:37
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
- ScienceDaily
- 22/1/6 20:37
'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...

Engineers have found that conduction of heat plays a larger role than previously thought in the dynamics of droplets on smooth surfaces that repel water.
Astronomers capture red supergiant’s death throes
- ScienceDaily
- 22/1/6 20:36
Astronomers previously believed that red supergiant stars fell dormant at the end of their lives. A new study shows that red supergiant stars can violently erupt before collapsing into supernovae
Archaeological dig reveals participants in California’s Gold Rush dined on salted Atlantic cod
- ScienceDaily
- 22/1/6 20:36
An excavation at Thompson's Cove in San Francisco shows 'Atlantic cod were imported during the 1850s, likely as a (largely) deboned, dried and salted product from the East Coast of the United States.' The analysis underscores the importance of global maritime trade in northern California during the Gold Rush.
Clinicians report real-world results on the use of a new device to treat brain aneurysms
- ScienceDaily
- 22/1/6 20:36
In an international study of patients with brain aneurysms (balloon-like bulges in weakened blood vessels), the Woven Endobridge device had a favorable efficacy and safety profile.
Microbes produce oxygen in the dark
- ScienceDaily
- 22/1/6 20:36
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
- ScienceDaily
- 22/1/6 20:32
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...
Nematicity is a new piece in a phase diagram puzzle
- ScienceDaily
- 22/1/6 19:33
A team sees stripes in samples of twisted double bilayer graphene, indicating the presence of a nematic phase characterized by broken rotational symmetry.
Unlocking the secrets of a critical schistosomiasis drug
- ScienceDaily
- 22/1/6 19:33
For decades, no one really knew how the drug praziquantel treated a parasitic disease afflicting more than 200 million people around the world. Now, two independent teams of researchers have found the answer.
Innovative approach brings cell-reprograming therapy for heart failure closer to reality
- ScienceDaily

Researchers have developed a new cell reprogramming strategy can change large scar tissue in rat hearts into working muscle.
Sending life to the stars
- ScienceDaily
- 22/1/6 19:32
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...

Zoo air contains enough DNA to identify the animals inside
- ScienceDaily
- 22/1/6 17:15
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,...

Unexpected hope for millions as bleached coral reefs continue to supply nutritious seafood
- ScienceDaily
- 22/1/6 17:15
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...
