| How fasting diets could harm future generations Posted: 11 May 2021 05:11 PM PDT New research which shows that fasting diets could harm the health of future generations. Fasting diets have risen in popularity in recent years, however little is known about the long-term impact of these diets, particularly for future generations. The new study reveals that reduced food intake in roundworms has a detrimental effect on three generations of offspring - particularly when those descendants have access to unlimited food. |

| Patients may not take advice from AI doctors who know their names Posted: 11 May 2021 06:20 AM PDT Researchers found that people may be less likely to take health advice from an AI doctor when the robot knows their name and medical history. On the other hand, patients want to be on a first-name basis with their human doctors. |
| Protecting local water has global benefits Posted: 11 May 2021 06:20 AM PDT A new article demonstrates why keeping local lakes and other waterbodies clean produces cost-effective benefits locally and globally. |
| People are persuaded by social media messages, not view numbers Posted: 11 May 2021 05:12 AM PDT People are more persuaded by the actual messages contained in social media posts than they are by how many others viewed the posts, a new study suggests. Researchers found that when people watched YouTube videos either for or against e-cigarette use, their level of persuasion wasn't directly affected by whether the video said it was viewed by more than a million people versus by fewer than 20. |
| New material to treat wounds can protect against resistant bacteria Posted: 11 May 2021 05:12 AM PDT Researchers have developed a new material that prevents infections in wounds - a specially designed hydrogel, that works against all types of bacteria, including antibiotic-resistant ones. The new material offers great hope for combating a growing global problem. |
| In 'minibrains,' hindering key enzyme by different amounts has opposite growth effects Posted: 11 May 2021 05:12 AM PDT Surprising findings can help improve organoid cultures, explain role of GSK3-beta in brain development. |
| Horseradish flea beetle: Protected with the weapons of its food plant Posted: 11 May 2021 05:12 AM PDT Researchers demonstrate how the horseradish flea beetle regulates the accumulation of mustard oil glucosides in its body. The beetles have special transporters in the excretory system that prevent the excretion of mustard oil glucosides. This mechanism enables the insect to accumulate high amounts of the plant toxins in its body, which it uses for its own defense. |
| Glyphosate inhibits symbiotic bacteria in the saw-toothed grain beetle Posted: 11 May 2021 05:12 AM PDT Susceptibility of their microbial partners to the herbicide may be an underestimated weak spot of insects that could add to their decline. |
| A comprehensive map of the SARS-CoV-2 genome Posted: 11 May 2021 05:12 AM PDT Researchers have generated what they describe as the most complete gene annotation of the SARS-CoV-2 genome. In their study, they confirmed several protein-coding genes and found that a few others that had been suggested as genes do not code for any proteins. |
| Boosting body heat production: A new approach for treating obesity Posted: 11 May 2021 05:12 AM PDT Targeting a heat production 'brake' on fat tissues may be a safer way to treat obesity than current medication. |
| Hidden within African diamonds, a billion-plus years of deep-earth history Posted: 11 May 2021 05:12 AM PDT A team has come up with a way to solve two longstanding puzzles: the ages of individual fluid-bearing diamonds, and the chemistry of their parent material. The research has allowed them to sketch out geologic events going back more than a billion years -- a potential breakthrough not only in the study of diamonds, but of planetary evolution. |
