Gene linked to severe learning disabilities governs cell stress response
- ScienceDaily
- 22/5/27 22:02
A gene that has been associated with severe learning disabilities in humans has been found to also play a vital role in cells' response to environmental stress, according to a new study. The gene, Rad6 has previously been associated with a set of symptoms called 'Nascimento Syndrome,' that include severe learning disabilities.

Novel sensors enable precise measurement of dopamine
- ScienceDaily
- 22/5/27 18:14
Dopamine is an important signalling molecule for nerve cells. Its concentration could not be precisely determined with both high spatial or temporal resolution until now. A new method has now made this possible: A research team used modified carbon nanotubes that glow brighter in the presence of the messenger substance dopamine. These sensors visualize the release of dopamine from nerve cells with...
Algorithms help to distinguish diseases at the molecular level

- 22/5/27 18:14
Machine learning is playing an ever-increasing role in biomedical research. Scientists have now developed a new method of using molecular data to extract subtypes of illnesses. In the future, this method can help to support the study of larger patient groups.
Learning from nature: Biosynthesis of cyanobacterin opens up new class of natural compounds for applications in medicine and agriculture
- ScienceDaily
- 22/5/27 18:13
Researchers have succeeded in understanding the biosynthetic mechanisms for the production of the natural product cyanobacterin, which is produced in small quantities by the cyanobacteria Scytonema hofmanni. In the process, they also discovered a new class of enzymes for building carbon-carbon bonds. The (bio)chemists are thus significantly expanding the biocatalytic repertoire currently known...
T cell warriors need their R & R
- ScienceDaily
- 22/5/27 18:13
T cells, biology textbooks teach us, are the soldiers of the immune system, constantly on the ready to respond to a variety of threats, from viruses to tumors. However, without rest and maintenance T cells can die and leave their hosts more susceptible to pathogens, scientists report.
High cost of cancer care in the U.S. doesn't reduce mortality rates
- ScienceDaily
- 22/5/27 18:13
In a new study, researchers find that the U.S. spends twice as much as the average high-income country on cancer care, but only has slightly better mortality rates.
An arms race that plays out in a single genome
- ScienceDaily
- 22/5/27 18:13
We often think of biological arms races occurring between the immune system and pathogens, or predator and prey, but biologists have now discovered an example that plays out within a single genome. Their work in fruit flies may have implications for key biological processes in humans, including fertility and even cancer.
A quarter of the world's Internet users rely on infrastructure that is susceptible to attacks
- ScienceDaily
- 22/5/27 16:12
About a quarter of the world's Internet users live in countries that are more susceptible than previously thought to targeted attacks on their Internet infrastructure. Many of the at-risk countries are located in the Global South. That's the conclusion of a sweeping, large-scale study conducted by computer scientists.
Ancient viral elements embedded in human genome not from fossil retrovirus
- ScienceDaily
- 22/5/27 16:12
Many types of animals, including humans, successfully coexist with retroviruses, and we know that ancient retrovirus viral elements can even be found within our genome. We also know that these endogenous retroviruses can be utilized for development and evolution. However, uncontrolled endogenous retroviruses may be a cause of disease in the human body. Now, researchers have discovered that...
Spines of life: Fast-breeding sea urchin provides new model for genetic research
- ScienceDaily
- 22/5/27 16:12
Researchers have established the sea urchin species Temnopleurus reevesii as a new model for genetic research. Unlike urchins previously used as biological models, T. reevesii has a short breeding cycle and other features that make it ideal for genetic studies. The team created two genome databases that will contribute to numerous fields, and enable future studies to find an even better model for...
Siberian tundra could virtually disappear by mid-millennium
- ScienceDaily
- 22/5/27 16:12
Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which are home to a unique mix of flora and fauna. Experts have now prepared a computer simulation of how these woods could spread in the future, at the tundra's expense.
