| A better informed society can prevent lead poisoning disasters Posted: 18 Sep 2020 12:45 PM PDT An article address unresolved scientific questions that can help avert future lead poisoning disasters. A better-informed society can prevent such disasters from happening through improved risk assessment, anticipation and management of factors affecting lead release.      |
| Connecting the dots on food access Posted: 18 Sep 2020 10:59 AM PDT A new study simultaneously examined the preferences of community members and compared those with the community-based programs and resources available to identify the most viable strategies for addressing disparities in healthy food consumption. |
| Nose's response to odors more than just a simple sum of parts Posted: 18 Sep 2020 07:42 AM PDT Based on highly sensitive recordings of neuron activity in the noses of mice, researchers have found that olfactory sensory neurons can exhibit suppression or enhancement of response when odors are mixed, overturning a long-standing view that the response is a simple sum with more complex processing only happening at later stages. |
| Unverricht-Lundborg disease is more common in Finland than elsewhere in the world Posted: 18 Sep 2020 07:42 AM PDT Based on reported cases, Unverricht-Lundborg disease, also known as progressive myoclonic epilepsy-1A, EPM1, is more common in Finland than anywhere else in the world, a new study finds. |
| Mosquito-borne viruses linked to stroke Posted: 18 Sep 2020 07:42 AM PDT A deadly combination of two mosquito-borne viruses may be a trigger for stroke, new research has found. |
| Mapping the decision-making pathways in the brain Posted: 18 Sep 2020 07:42 AM PDT Scientists have identified a new area of the brain that could be involved in cost-benefit decision-making. |
| Coffee associated with improved survival in metastatic colorectal cancer patients Posted: 17 Sep 2020 03:12 PM PDT In a large group of patients with metastatic colorectal cancer, consumption of a few cups of coffee a day was associated with longer survival and a lower risk of the cancer worsening, researchers report in a new study. |
| New high-speed test shows how antibiotics combine to kill bacteria Posted: 17 Sep 2020 03:12 PM PDT Researchers have developed a new method to determine - rapidly, easily and cheaply - how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for laboratories to use and can provide greater scope for customizing treatment of bacterial infections. |
| Quizzes improve academic performance Posted: 17 Sep 2020 03:04 PM PDT Students who are quizzed over class material at least once a week tend to perform better on midterm and final exams compared to students who did not take quizzes, according to a new meta-analysis. The researchers found in addition to frequency, immediate feedback from instructors also seemed to positively impact student performance. |
| Algorithms uncover cancers' hidden genetic losses and gains Posted: 17 Sep 2020 03:02 PM PDT Limitations in DNA sequencing technology make it difficult to detect some major mutations often linked to cancer, such as the loss or duplication of parts of chromosomes. Now, methods developed by computer scientists will allow researchers to more accurately identify these mutations in cancerous tissue, yielding a clearer picture of the evolution and spread of tumors than was previously possible. |
| Novel mechanism may confer protection against glaucoma Posted: 17 Sep 2020 10:55 AM PDT Researchers provides the first evidence that patients with ocular hypertension may exhibit superior antioxidant protection that promotes resistance to the elevated intraocular pressure associated with glaucoma. |
| Consumers value difficult decisions over easy choices Posted: 17 Sep 2020 10:52 AM PDT Researchers found that disfluency, or the difficulty for an individual to process a message, increases people's attitudes toward that message after a time delay. |
| Keys to control the 'driver of cancer's aggressiveness' Posted: 17 Sep 2020 09:28 AM PDT A dangerous protein named SNAI2 helps cancers metastasize and shields cancer from both the immune system and chemotherapy. Worse, SNAI2 is in a family of proteins that are notoriously hard to fight with drugs. But now researchers have found a way to use the cell's recycling system to control SNAI2, providing a new possibility for treatments. |
| How Dantu blood group protects against malaria, and how all humans could benefit Posted: 16 Sep 2020 08:35 AM PDT The secret of how the Dantu genetic blood variant helps to protect against malaria has been revealed for the first time. The team found that red blood cells in people with the rare Dantu blood variant have a higher surface tension that prevents them from being invaded by the world's deadliest malaria parasite, Plasmodium falciparum. |
| Generation of three-dimensional heart organoids Posted: 16 Sep 2020 06:42 AM PDT Researchers engineered three-dimensional functional heart organoids resembling the developing heart. By exposing mouse embryonic stem cells to two key proteins during heart development, the researchers were able to form heart organoids with structural, functional, and molecular similarities to the embryonic heart during development. This method could be used to study heart development and to screen for novel drugs against heart disease. |
| Potent drug supply drop, not domestic drug policies, likely behind 2018 OD death downturn Posted: 16 Sep 2020 06:05 AM PDT The slight decline in drug overdose deaths in 2018 coincides with Chinese regulations on the powerful opioid carfentanil, rather than the result of domestic U.S. efforts to curb the epidemic, a new analysis reveals. What many - including President Donald Trump - perceived as a decline in overdose deaths in 2018, appears to be a return to the historic exponential curve. |
