Stretching diamond for next-generation microelectronics
- ScienceDaily
- 20/12/31 20:15
Diamond is the hardest material in nature. It also has great potential as an excellent electronic material. A research team has demonstrated for the first time the large, uniform tensile elastic straining of microfabricated diamond arrays through the nanomechanical approach.

Spontaneous robot dances highlight a new kind of order in active matter
- ScienceDaily
- 20/12/31 20:15
Researchers have proposed a new principle by which active matter systems can spontaneously order, without need for higher level instructions or even programmed interaction among the agents. And they have demonstrated this principle in a variety of systems, including groups of periodically shape-changing robots called 'smarticles.'

Allergists offer reassurance regarding potential allergic reactions to COVID-19 vaccines
- ScienceDaily
- 20/12/31 19:16
Reports of possible allergic reactions to COVID-19 vaccines have raised public concern; however, allergists note that allergic reactions to vaccines are rare, and COVID-19 vaccine allergic reactions will have a similarly low rate of occurrence.
Social media safety messages: Pictures should match the words
- ScienceDaily
- 20/12/31 16:07
When using social media to nudge people toward safe and healthy behaviors, it's critical to make sure the words match the pictures, according to a new study. After looking at social media posts, parents of young children were better able to recall safety messages such as how to put a baby safely to sleep when the images in the posts aligned with the messages in the text.
Study points the way to boost immunotherapy against breast cancer, other solid tumors
- ScienceDaily
- 20/12/31 16:07
Researchers report that adding a small molecule to a chimeric antigen receptor-T (CAR-T) cell therapy can help immune system T cells to effectively attack solid tumors, such as breast cancers. The boost helps recruit more immune cells into battle at the tumor site, according to the new study.
Blood vessel cells implicated in chronic inflammation of obesity
- ScienceDaily
- 20/12/31 15:10
When fat cells in the body are stuffed with excess fat, the surrounding tissue becomes inflamed. That chronic, low-level inflammation is one of the driving factors behind many of the diseases associated with obesity. Now, scientists have discovered a type of cell responsible, at least in mice, for triggering this inflammation in fat tissue. Their findings could eventually lead to new ways to treat...
Transfusions with higher red blood cell levels do not improve preterm baby outcomes
- ScienceDaily
- 20/12/31 15:10
A randomized clinical trial is the largest study to-date to compare thresholds for blood transfusions in premature babies, offers guidance for health care providers.

Scientists explore deficits in processing speed in individuals with spinal cord injury
- ScienceDaily
- 20/12/30 22:12
A new study examined the neural mechanisms of higher order cognitive tasks of individuals with SCI.
New research may explain severe virus attacks on the lungs
- ScienceDaily
- 20/12/30 20:19
In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study may contribute to future treatments for COVID-19, among other diseases.
Potential new RX strategy for stroke
- ScienceDaily
- 20/12/30 17:43
new research reports that a combination of a new drug and selected DHA derivatives is more effective in protecting brain cells and increasing recovery after stroke than a single drug.
Development of fusion energy

The SUTD study will be crucial for assessing future climatic changes and making more informed water management decisions.
A pursuit of better testing to sort out the complexities of ADHD
- ScienceDaily
- 20/12/30 15:42
The introduction of computer simulation to the identification of symptoms in children with attention deficit/hyperactivity disorder (ADHD) has potential to provide an additional objective tool to gauge the presence and severity of behavioral problems, researchers suggest.

Imaging of ballistic wounds, bullet composition and implications for MRI safety
- ScienceDaily
- 20/12/29 23:55
Since patients with ballistic embedded fragments are frequently denied MRI (due to indeterminate bullet composition sans shell casings), radiography and CT can be used to identify nonferromagnetic projectiles that are safe for MRI.

Stopping RAS inhibitors tied to worse outcomes in patients with chronic kidney disease
- ScienceDaily
- 20/12/29 16:45
Small studies have suggested that a group of medications called RAS inhibitors may be harmful in persons with advanced chronic kidney disease, and physicians therefore often stop the treatment in such patients. Researchers now show that although stopping the treatment is linked to a lower risk of requiring dialysis, it is also linked to a higher risk of cardiovascular events and death.
