An international team of scientists identified the snake and its range, which includes Turkey, Azerbaijan, Armenia, Georgia, Iraq, Iran, and Russia including a small region extending into the corner of...

New genetic engineering strategy makes human-made DNA invisible

1 week ago from

Bacteria are everywhere. They live in the soil and water, on our skin and in our bodies. Some are pathogenic, meaning they cause disease or infection. To design effective treatments...

A team from the transdisciplinary laboratory FoAM Kernow and the British Science Association detail how to run an innovative approach to understanding evidence called AccessLab in a paper published on...

'Neural Lander' uses AI to land drones smoothly

1 week ago from

Control engineers and AI experts team up to make drones that fly more smoothly close to the ground.

Gut is organized by function, and opportunities for better drug design

1 week ago from

New findings provide insights about how the intestine maximizes nutrient uptake, while at the same time protecting the body from potentially dangerous microbes.

More than a protein factory: A role for ribosomes in regulating human gene expression

1 week ago from

Researchers have discovered a new function of ribosomes in human cells that may show the protein-making particle's role in destroying healthy mRNAs, the messages that decode DNA into protein.

Paper stickers to monitor pathogens are more effective than swabs

1 week ago from

Using paper stickers to collect pathogens on surfaces where antisepsis is required, such as in food processing plants, is easier, and less expensive than swabbing, yet similarly sensitive.

Coat of proteins makes viruses more infectious and links them to Alzheimer's disease

1 week ago from

New research shows that viruses interact with proteins in the biological fluids of their host which results in a layer of proteins on the viral surface. This coat of proteins...

Exploring the origins of the apple

1 week ago from

Apples originally evolved in the wild to entice ancient megafauna to disperse their seeds. More recently, humans began spreading the trees along the Silk Road with other familiar crops. Dispersing...

New causes of autism found in 'junk' DNA

1 week ago from

Leveraging artificial intelligence techniques, researchers have demonstrated that mutations in so-called 'junk' DNA can cause autism. The study is the first to functionally link such mutations to the neurodevelopmental condition...

How language developed: Comprehension learning precedes vocal production

1 week ago from

Researchers recently investigated how the closely related West African green monkeys react to unknown sounds.

Scientists uncover a trove of genes that could hold key to how humans evolved

1 week ago from

New computational analysis finds that more than two dozen human zinc finger transcription factors, previously thought to control activity of similar genes across species have in fact human-specific roles and...

Group A strep genome research expedites vaccine development efforts

1 week ago from

The global search for a group A streptococcal (Strep A) vaccine has narrowed after researchers identified a common gene signature in almost all global Strep A strains by sequencing thousands...

Broken brain cells repaired in dementia mouse model

1 week ago from

Dysfunctional neurons in the hippocampus of adult female mice modeling dementia can be repaired and reconnected to distant parts of the brain, reports a new study. The similarity between the...

Unexpected survival mechanism of a subset of cancer cells revealed

1 week ago from

Researchers have discovered that a human enzyme named FANCM is required for the survival of ALT tumor cells. Future strategies targeting the activity of this molecule in ALT tumor cells...

Inhibitory neurons have two types of impact on brain oscillations

1 week ago from

Synchronization is important to understanding how neurons behave, which is particularly relevant with regard to brain diseases like Alzheimer's, epilepsy and Parkinson's. Now, a group of researchers has used a...

New genetic engineering strategy makes human-made DNA invisible

1 week ago from

Scientists have developed a new technique to genetically engineer bacteria by making human-made DNA invisible to a bacterium's defenses. In theory, the method can be applied to almost any type...
