The deletion of the autism-associated Tbx1 gene results in slower cognitive processing and decreased myelin in mouse models.

A brain network implicated in learning by trial and error also becomes engaged when people adapt to social norms, a new study reports. Findings suggest people learn from social information similarly to learning by trial ...

Miniaturization of optical components is a challenge in photonics. Researchers of Karlsruhe Institute of Technology (KIT) and Friedrich Schiller University of Jena have now succeeded in developing a diffuser, a disk that...

Are electric toothbrushes better than manual brushes? We explore how to get the best results from our toothbrushes.

A large, unconventional anomalous Hall resistance in a new magnetic semiconductor in the absence of large-scale magnetic ordering has been demonstrated by Tokyo Tech materials scientists, validating a recent theoretical ...

Scientists have identified a series of molecular candidates for those parts of dog allergens that cause immune reactions in people--the first step in developing a vaccine against most causes of dog allergies.

In an effort to make sense of new COVID-19 variants, scientists have developed methods to quantify how much more or less transmissible they are, which could have far-reaching implications for public health in terms of CO...

From the smooth tubes of our arteries and veins to the textured pockets of our internal organs, our bodies are made of tissues arranged in complex shapes that aid in performing specific functions.

A molecular building block of many animal proteins, the amino acid valine, plays a key role in cancerous growth seen in T cell acute lymphoblastic leukemia, a new study shows.

The smallest fish in the world, the Paedocypris, measures only 7 millimeters. This is nothing compared to the 9 meters of the whale shark. The small fish shares many of the same genes and the same anatomy with the shark,...

An interdisciplinary Danish team of researchers has used new astronomical knowledge to establish an exact time anchor for the arrival of trade flows from the Middle East in Viking-age Scandinavia. The results are publish...

A new study shows how the brown anole lizard solves one of nature's most complex problems -- breathing -- with ultimate simplicity. Whereas human lungs develop over months and years into baroque tree-like structures, the...

Large-scale in Norway finds the evolutionary fitness of wild Altantic salmon is being damaged after they breed with escaped fish from the country's huge aquaculture industry

While conventional electronics relies on the transport of electrons, components that convey spin information alone may be many times more energy efficient. Physicists at the Technical University of Munich (TUM) and the M...

The growing interest in deep-space exploration has sparked the need for powerful long-lived rocket systems to drive spacecraft through the cosmos. Scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Phys...

Free-floating planets are hard to spot, but astronomers have bagged a large haul by looking for candidates in a nearby star-forming region

Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics--circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schem...

Analysis of ancient DNA reveals a mass migration of people from what is now France to England and Wales between 1000 and 875 BC

Understanding why plant-eating mammals like antelopes and sheep are far less likely to die of cancer than carnivores may help protect us from cancer too

For the first time, grafting has been made to work in monocots, a type of plant including oats, wheats and bananas - and it might improve disease tolerance among these important crops

A Neolithic tomb in England holds the remains of five generations of family members descended from one man and four women, DNA analysis reveals.

A Rice University-led study is forcing physicists to rethink superconductivity in uranium ditelluride, an A-list material in the worldwide race to create fault-tolerant quantum computers.
