The researchers analysed human atherosclerotic lesions to map the chromatin accessibility of more than 7,000 cells. |
| Climate changed the size of our bodies and, to some extent, our brains Posted: 08 Jul 2021 05:39 AM PDT The average body size of humans has fluctuated significantly over the last million years and is strongly linked to temperature. Colder, harsher climates drove the evolution of larger body sizes, while warmer climates led to smaller bodies. Brain size also changed dramatically but did not evolve in tandem with body size. |
| Novel study of high-potency cannabis shows some memory effects Posted: 08 Jul 2021 05:38 AM PDT Researchers observed participants over Zoom as they used high-potency cannabis they purchased themselves from dispensaries in Washington state, where recreational cannabis is legal. After administering cognitive tests, researchers found no impact on users' performance on decision-making tests in comparison to a sober group but did find memory impairments related to free recall, source memory and false memories. This study is one of the few to investigate cannabis flower and concentrates containing more than 10% THC. |
| Posted: 07 Jul 2021 03:53 PM PDT If global warming is not curbed, the increase in heat-related deaths will outstrip the decline in cold-related mortality, especially in the Mediterranean Basin, a new study concludes. |
| Protein's 'silent code' affects how cells move Posted: 07 Jul 2021 03:53 PM PDT Two forms of the ubiquitous protein actin differ by only four amino acids but are dissimilar in 13% of their nucleotide coding sequences due to silent substitutions. A new study reveals that these supposedly 'silent' differences have an impact on how fast actin mRNA gets translated into protein and subsequently on the protein's function in propelling cell movement. |
| More EVs could reduce CO2 emissions in Hawaii by 93% in less than 30 years Posted: 07 Jul 2021 03:53 PM PDT By 2050, faster adoption of electric vehicles (EVs) and faster generation of renewable energy will result in 99% less fossil fuel consumed and 93% less CO2 emissions from passenger and freight vehicles on Oahu. |
