How many Earth-like planets are around sun-like stars?

A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun.

Barn owls may hold key to navigation and location

Engineers have created an electronic circuit that can slow down the input signals and determine the coincidence point, mimicking the working of the barn owl brain.
A random-forest, machine-learning method for identifying copy number variation from exome-sequencing data. A forest of hundreds of decision trees is trained on a validated set of genetic deletions and duplication, the model built from these trees can then be used to accurately identify copy number variation in sample exome-sequencing data.

New technique can find deletions and duplications in the human genome

Copy number variants (CNVs) are a noteworthy reason for a few genetic disorders, making their identification an essential segment of genetic analysis pipelines. Current...

Atypical eating behaviors may be a new diagnostic indicator for autism

Atypical eating behavior may include severely limited food preferences, hypersensitivity to food texture or temperatures, and pocketing food without swallowing. Such action is a...
Gluconate, a small organic molecule, inhibits neonatal seizures in rodent models and could open up new avenues for the treatment of epilepsy in human newborns. The image illustrates the structure of neonatal hippocampus (green), overlaid with a typical electrophysiological trace of seizure activity, and the molecular structure of gluconate.

A new drug that inhibits neonatal seizures

Neonatal seizures or neonatal convulsions are epileptic fits occurring from birth to the end of the neonatal period. The neonatal period is the most...

Psychology may help explain why male and female serial killers differ

A recent study has found that male serial killers and female serial killers choose their victims and commit crimes in different ways. Male serial...
