| When it comes to communication skills, maybe we’re born with it? Posted: 24 Sep 2021 03:25 PM PDT A neuroscientist and speech pathologist, led a study that uncovered how neural networks in infants influence their language learning skills in early childhood. |
| In a gene tied to growth, scientists see glimmers of human history Posted: 24 Sep 2021 03:25 PM PDT A new study delves into the evolution and function of the human growth hormone receptor gene, and asks what forces in humanity's past may have driven changes to this vital piece of DNA. |
| Guiding microbes along their path Posted: 24 Sep 2021 07:43 AM PDT The direction of movement of a microbe directly depends on the curvature of its environment, according to new findings. The researchers investigated the navigation of a model microbe, a small self-propelling microalga, in confined compartments with different shapes. They also developed theoretical models to predict the probability flux of that microswimmer which was confirmed by experiments. With this model available, it is now possible to pre-define the average trajectory of such microbes by manipulating the curvature of the compartments which directly affects their movement. |
| Insights from our genome and epigenome will help prevent, diagnose and treat cancer Posted: 24 Sep 2021 07:43 AM PDT In 2020, an estimated 10 million people lost their lives to cancer. This devastating disease is underpinned by changes to our DNA -- the instruction manual for all our cells. |
| New cause of inherited heart condition discovered Posted: 24 Sep 2021 07:42 AM PDT The discovery provides a new causal explanation for 1-2% of adults with the condition. |
| Radiation therapy reprograms heart muscle cells to younger state Posted: 24 Sep 2021 07:40 AM PDT New research suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure. |
| Lab grown tumor models could improve treatment for pancreatic cancer Posted: 24 Sep 2021 04:55 AM PDT An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments. |
| Wide heads help sperm swim together Posted: 23 Sep 2021 01:59 PM PDT Researchers used machine learning to discover that sperm with a wide head relative to length are more likely to clump together and swim collectively, a rare behavior that sometimes helps them reach an egg faster. The study provides a new method for understanding how form and function are related in cells with complex behaviors in all animals, including humans. |
