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. |

| What to do with food waste? Well, that depends Posted: 07 Jul 2021 01:05 PM PDT The expected decline in the number of landfills across the United States coupled with bans on disposing large amounts of organic waste in landfills that have been enacted in multiple states has prompted researchers to examine other ways to grapple with the issue of food waste disposal. |
| Could ketogenic diet be helpful with brain cancer? Posted: 07 Jul 2021 01:05 PM PDT A modified ketogenic diet may be worth exploring for people with brain tumors, according to a new study. The small study found that the diet was safe and feasible for people with brain tumors called astrocytomas. The study was not designed to determine whether the diet could slow down tumor growth or improve survival. |
| How plants compensate symbiotic microbes Posted: 07 Jul 2021 01:05 PM PDT Combining economics, psychology and studies of fertilizer application, researchers find that plants nearly follow an 'equal pay for equal work' rule when giving resources to partner microbes - except when those microbes under-perform. |
| When taste and healthfulness compete, taste has a hidden advantage Posted: 07 Jul 2021 01:05 PM PDT You dash into a convenience store for a quick snack, spot an apple and reach for a candy bar instead. Poor self-control may not be the only factor behind your choice, new research suggests. That's because our brains process taste information first, before factoring in health information, according to new research. |
| Human-driven habitat change leads to physical, behavioral change in mosquitofish Posted: 07 Jul 2021 01:04 PM PDT Bahamian mosquitofish in habitats fragmented by human activity are more willing to explore their environment, more stressed by change and have smaller brain regions associated with fear response than mosquitofish from unaffected habitats. |
