Ancient reptile had mammal-like tooth enamel
- ScienceDaily
- 20/5/12 21:20
A new study by paleontologists shows that one type of ancient reptiles evolved a special type of tooth enamel, similar to that of mammals, with high resistance to wear and tear. The study is the first to report this kind of enamel in a fossil reptile.

Marine waste management: Recycling efficiency by marine microbes
- ScienceDaily
- 20/5/12 21:19
It was only relatively recently that tiny, single-celled thaumarchaea were discovered to exist and thrive in the pelagic ocean, where their population size of roughly 1028 (10 billion quintillion) cells makes them one of the most abundant organisms on our planet.
Silver nanocubes make point-of-care diagnostics easier to read
- ScienceDaily
- 20/5/12 21:19
Engineers have shown that nanosized silver cubes can make diagnostic tests that rely on fluorescence easier to read by making them more than 150 times brighter. Combined with an emerging point-of-care diagnostic platform already shown to be able to detect small traces of viruses and other biomarkers, the approach could allow such tests to become much cheaper and more widespread.
Powerful new AI technique detects and classifies galaxies in astronomy image data
- ScienceDaily
- 20/5/12 21:19
Researchers have developed a powerful new computer program called Morpheus that can analyze astronomical image data pixel by pixel to identify and classify all of the galaxies and stars in large data sets from astronomy surveys. Morpheus is a deep-learning framework that incorporates a variety of artificial intelligence technologies developed for applications such as image and speech recognition.
New software supports decision-making for breeding
- ScienceDaily
- 20/5/12 21:19
Researchers have developed an innovative software program for the simulation of breeding programs. The ''Modular Breeding Program Simulator'' (MoBPS) enables the simulation of complex breeding programs in animal and plant breeding and is designed to assist breeders in their everyday decisions. In addition to economic criteria in breeding, the research team strives for goals such as sustainability,...
Dogs can detect traces of gasoline down to one billionth of a teaspoon
- ScienceDaily
- 20/5/12 21:19
Trained dogs can detect fire accelerants such as gasoline in quantities as small as one billionth of a teaspoon, according to new research by chemists. The study provides the lowest estimate of the limit of sensitivity of dogs' noses and has implications for arson investigations.
A combo of fasting plus vitamin C is effective for hard-to-treat cancers, study shows
- ScienceDaily
- 20/5/12 21:19
Researchers have discovered that a fasting-mimicking diet could be more effective at treating some types of cancer when combined with vitamin C. In studies on mice, researchers found that the combination delayed tumor progression in multiple mouse models of colorectal cancer; in some mice, it caused disease regression.
New tool helps distinguish the cause of blood clots
- ScienceDaily
- 20/5/12 21:19
A new tool using cutting-edge technology is able to distinguish different types of blood clots based on what caused them, according to a new study.
Protein that helps cancer cells to survive
- ScienceDaily
- 20/5/12 21:19
In a new study, researchers have discovered two important functions of a protein called RTEL1 during cell division. The researchers hope that the new knowledge will help to find new cancer treatments.
How memory function could be preserved after brain injury
- ScienceDaily
- 20/5/12 21:19
A new study examining the effect of the immune receptor known as Toll-like Receptor 4, or TLR4, on how memory functions in both the normal and injured brain has found vastly different cellular pathways contribute to the receptor's effects on excitability in the uninjured and injured brain. Further, the researchers found novel mechanisms for how TLR4 regulates memory function in the normal,...

Psychologists find that we are less likely to amplify fears in social exchange if we are stressed.
Little skates could hold the key to cartilage therapy in humans
- ScienceDaily
- 20/5/12 19:45
Unlike humans and other mammals, the skeletons of sharks, skates, and rays are made entirely of cartilage and they continue to grow that cartilage throughout adulthood. New research finds that adult skates go one step further than cartilage growth: They can also spontaneously repair injured cartilage. This is the first known example of adult cartilage repair in a research organism. The team also...
The butterfly effect: Climate change could cause decline of some alpine butterfly species
- ScienceDaily
- 20/5/12 19:45
The long-term effects of climate change suggests that the butterfly effect is at work on butterflies in the alpine regions of North America, according to a new study -- and the predictions don't bode well.
AI techniques in medical imaging may lead to incorrect diagnoses
- ScienceDaily
- 20/5/12 19:45
Machine learning and AI are highly unstable in medical image reconstruction, and may lead to false positives and false negatives, a new study suggests.
