How alike are the cancer cells from a single patient?

Added: 11.11.2021 22:19 | 207 views | 0 comments

Using an experimental system involving new genetic technology, researchers analyzed the gene expression signatures of a representative sample of barcoded leukemia cells. After implanting some of the leukemia cells in mice, they discovered that distinct gene expression signatures correlated with the various organs where the cancer cells ended up. They were also able to identify previously unknown genes that are involved in disease progression and chemotherapy resistance, which may offer new targets for treatment.

Environmental implications of ultra-processed foods

A new study finds that over the last 30 years, Brazil has undergone a nutrition transition toward a diet higher in ultra-processed foods, and that of food types consumed, these have been the largest contributor to worsening impacts on greenhouse gas emissions, the nation's water footprint and ecological footprint, such as deforestation.

Students who self-identify as multilingual perform better in exams

Added: 11.11.2021 22:19 | 204 views | 0 comments

Young people who consider themselves 'multilingual' tend to perform better across a wide range of subjects at school, regardless of whether they are actually fluent in another language, new research suggests. The study of more than 800 pupils in England found a measurable, positive relationship between their personal connection with other languages, and their GCSE exam results in both modern language and non-language subjects. This applied whether or not they actually spoke a second language fluently.

Inputs and impacts of human wastewater in coastal ecosystems

Added: 11.11.2021 22:19 | 207 views | 0 comments

The tendency for most of us when it comes to human wastewater is out of sight, out of mind. Rarely do we consider what happens after we flush that toilet or turn off that tap. However, researchers have turned their attention and considerable computational power to the subject and its impacts on global coastal ecosystems. The results aren't pretty, but they are enlightening.

'Tug of war' between cells – When crucial connections are missing

Added: 11.11.2021 22:19 | 206 views | 0 comments

The ability of cells to move together in harmony is crucial for numerous biological processes in our body, for example, wound healing, or the healthy development of an organism. This movement is made possible by the connections between individual cells. A research team has shown that particularly close connections -- 'tight junctions' -- play an important role in cell movement. In addition, researchers investigated the consequences of losing these connections.

Mosaic brain evolution in guppies helps to explain vertebrate cognitive evolution

Added: 11.11.2021 22:19 | 205 views | 0 comments

Researchers have provided the first experimental evidence that brain regions can evolve independently of each other during cognitive evolution. This so called mosaic brain evolution was verified empirically in an artificial selection experiment with guppies (Poecilia reticulata) where telencephalon size (but no other regions) differed by 10 percent after only four generations of selection. The findings can have wide implications for the understanding of cognitive evolution in other vertebrates, such as primates and humans.

A newly discovered genetic link to non-alcoholic inflammatory liver disease

Added: 11.11.2021 22:19 | 190 views | 0 comments

Researchers have shown that albino mice of the C57BL/6 line are highly susceptible to developing the inflammatory liver condition non-alcoholic steatohepatitis (NASH) when fed a high cholesterol diet. The albino mice carry a mutation in the tyrosinase gene leading to a deficiency of melanin synthesis. NASH is a serious illness in humans, and the identification of the involvement of tyrosinase in NASH development will guide future research into this condition.

Human Neurons are Strikingly Different from Those of Other Mammals, Study Says

Added: 11.11.2021 21:45 | 201 views | 0 comments

Human neurons have a much smaller number of channels that control the flow of ions (such as potassium and sodium) than expected, compared to the neurons of other mammals, according to new research led by MIT neuroscientists; and this reduction in channel density may have helped the human brain evolve to operate more efficiently, allowing [...]

Eggshell Exoplanets: Rocky Worlds with Ultra-Thin Brittle Lithospheres Could Theoretically Exist

The thickness of the brittle lithosphere - the outer portion of a planetary body that fails via fracturing - plays a key role in the geological processes of that body. The properties of both a planet and its host star can influence that thickness, and the potential range of those properties exceeds what researchers see [...]
