| 'I know this song!' Evolutionary keys to musical perception Posted: 25 Apr 2022 09:11 AM PDT When we hear a song that we already know, we can identify it even if it is not an exact version of the original. If it sounds higher or lower, faster or slower, or if the instruments are different from the known version, humans can identify it even if there are these superficial changes to the melody. New research explores the extent to which this skill is based on skills that are also present in other animals, i.e., not unique to humans. |
| Automated nutrition app can help people follow healthier diet Posted: 25 Apr 2022 09:11 AM PDT People could benefit from fully automated personal nutritional advice, as a new research paper shows that an app improved healthy diet in clinical trials. |
| Researchers discover drug-resistant environmental mold is capable of infecting people Posted: 25 Apr 2022 09:10 AM PDT A new study finds that drug-resistant mold is spreading from the environment and infecting susceptible people's lungs. |
| Reprogrammed macrophages promote spread of breast cancer Posted: 25 Apr 2022 09:10 AM PDT Metastatic breast cancer cells abuse macrophages, a type of immune cell, to promote the settlement of cancer metastases in the lungs. The reprogrammed macrophages stimulate blood vessel cells to secrete a cocktail of metastasis-promoting proteins that are part of the so-called metastatic niche. |
| Using AI to detect cancer from patient data securely Posted: 25 Apr 2022 09:10 AM PDT A new way of using artificial intelligence to predict cancer from patient data without putting personal information at risk has been developed. Swarm learning can be used to help computers predict cancer in medical images of patient tissue samples, without releasing the data from hospitals. |
| How equal charges in enzymes control biochemical reactions Posted: 25 Apr 2022 07:49 AM PDT It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes -- the biological catalysts in all living organisms -- form or break chemical bonds. |
| A friend, not foe: Parasite in gastrointestinal system found to promote health Posted: 25 Apr 2022 07:49 AM PDT Researchers have demonstrated that a gut parasite suppresses inflammation and improves the health of the gastrointestinal system. |
| Palmitoylation, a new target for anti-cancer drugs Posted: 25 Apr 2022 07:49 AM PDT By developing a tool to visualize the membrane association and activation status of normal and oncogenic proteins, scientists have established the basis for innovative drug discovery. |
| Learning from endangered zebra stem cells Posted: 25 Apr 2022 07:49 AM PDT Scientists have produced stem cells from the endangered Grévy's zebra using human reprogramming factors. Further comprehensive gene analyses identified key genes that are also found in human and mouse cells, providing insight into evolutionary conservation between mammals. |
| Offspring weakens when parents are given antibiotics Posted: 25 Apr 2022 07:48 AM PDT New study shows the immune system of zebrafish weakens if one parent has been exposed to antibiotics. Antibiotics can have unwanted effects for several generations, researchers discover. |
| Scientists discover mechanism behind chemically induced suppression of fearful memories Posted: 25 Apr 2022 07:43 AM PDT Fearful events negatively impact the brain. For instance, war veterans often go through post-traumatic stress disorder months after the cessation of the triggering event. Now, the precise mechanism of suppression of such fearful memories has been uncovered. Using a mouse model, the researchers identified the associated biochemical pathways, thus paving the way for the development and clinical evaluation of therapeutic compounds such as KNT-127. |
| Firearms kill more children than car crashes, new report finds Posted: 21 Apr 2022 03:11 PM PDT In an analysis of the most recent data available through the CDC, clinical researchers revealed that firearm injuries are now the leading cause of death among children up to age 19, and the racial gap between black and white youth is widening. The article calls for health care workers to recognize this as an epidemiological and public health challenge and to help find solutions. |
