| Using gene scissors to specifically eliminate individual cell types Posted: 04 Apr 2022 07:57 AM PDT With the help of the CRISPR/Cas molecular scissors, genetic information in a plant can be modified to make the latter more robust to pests, diseases, or extreme climatic conditions. Researchers have now developed this method further to eliminate the complete DNA of specific cell types and, thus, prevent their formation during plant development. This will also help researchers better understand development mechanisms in plants. |
| Monkeys routinely consume fruit containing alcohol, shedding light on our own taste for booze Posted: 01 Apr 2022 11:13 AM PDT Scientists analyzed the ethanol content of fruit eaten by spider monkeys in Panama, and found that the fruit regularly contained alcohol: between 1% and 2%. The researchers also collected urine samples, most of which contained secondary metabolites of ethanol. The results provide further evidence that our primate ancestors preferentially sought out fermented, alcohol-containing fruit likely for its greater nutritional value, and that humans may have inherited this proclivity for ethanol. |
| Posted: 01 Apr 2022 11:13 AM PDT The concept of a 'person' or 'people' is, despite its definition, not gender-neutral when it comes to how we use these terms. In fact, we tend to prioritize men when referring to people in general, shows a new study by a team of psychology and linguistics researchers. |
| Study shows: Fish can calculate Posted: 01 Apr 2022 09:22 AM PDT Cichlids and stingrays can perform simple addition and subtraction in the number range of one to five, according to new research. It is not known what the animals need their mathematical abilities for. |
| Gene linked to hearing in humans also linked to touch in sea anemones Posted: 01 Apr 2022 09:21 AM PDT Researchers have discovered a developmental gene linked to touch in the tentacles of sea anemones as well as hearing in humans. The gene, called pou-iv (pronounced 'pow four'), is important for the development of auditory cells in the human inner ear. |
| Perseverance records the first ever sounds from Mars Posted: 01 Apr 2022 09:21 AM PDT NASA's Perseverance rover, which has been surveying the surface of Mars since February 2021, has for the first time recorded the acoustic environment of the Red Planet. |
| Shapeshifting volcano virus points to new ways to deliver drugs, vaccines Posted: 01 Apr 2022 06:49 AM PDT A discovery about a shapeshifting virus found in hot volcanic springs could have very useful implications. |
| Fruit flies adapt activity to 'white nights' Posted: 31 Mar 2022 10:42 AM PDT Fruit flies with a new variant of a 'clock gene' are spreading northwards. Neurobiologists have now found an explanation for this phenomenon. |
| Posted: 31 Mar 2022 07:16 AM PDT An international team of scientists has proved that Mercury, our solar system's smallest planet, has geomagnetic storms similar to those on Earth. Their finding, a first, answers the question of whether other planets, including those outside our solar system, can have geomagnetic storms regardless of the size of their magnetosphere or whether they have an Earth-like ionosphere. |
| Flowers' unseen colors can help ensure pollination, survival Posted: 30 Mar 2022 07:33 AM PDT You can't see it, but different substances in the petals of flowers create a 'bulls-eye' for pollinating insects, according to a scientist whose research sheds light on chemical changes in flowers which helps them respond to environmental changes, including climate change, that might threaten their survival. |
