New genetic engineering strategy makes human-made DNA invisible

2 weeks 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...

AccessLab: New workshops to broaden access to scientific research

2 weeks ago from

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...

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

2 weeks 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

2 weeks 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

2 weeks 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

2 weeks 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

2 weeks 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

2 weeks 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

2 weeks 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

2 weeks 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

2 weeks 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...

Newly discovered mechanism reveals how Parkinson's disease can spread between brain cells

2 weeks ago from

Tiny channels between nerve cells are involved in a newly discovered mechanism of how Parkinson's disease can spread throughout the brain, according to new research from Linköping University, Sweden. The...

Stem cell identity unmasked by single cell sequencing technology

2 weeks ago from

Scientists have revealed the difference between a stem cell and other blood vessel cells using gene-sequencing technology.

New cable-free brain imaging method may take social neuroscience to the next level

2 weeks ago from

Researchers developed a cable-free recording method that can measure brain activity associated with social behavior in mice. The method was based on a bioluminescent indicator of membrane voltage called 'LOTUS-V',...

Finding a cell's true identity

2 weeks ago from

In a bid to reveal even more distinctive differences and similarities, researchers have developed two new artificial intelligence methods that decipher complex gene activity controlling cell fate decisions in retina...

New genetic engineering strategy makes human-made DNA invisible

2 weeks 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...

New mutations for herbicide resistance rarer than expected

2 weeks ago from

New evidence suggests that herbicide resistance in weeds is more likely to occur from pre-existing genetic variation than from new mutations.

AccessLab: New workshops to broaden access to scientific research
