The human heart beats more than two billion times in an average lifespan. The aorta’s tissue is strong enough to withstand this stress, yet flexible enough to maintain a steady flow of blood. But how ...
The Tin Man didn’t have one. The Grinch’s was three sizes too small. And for soft robots, the electronically powered pumps that function as their “hearts” are so bulky and rigid, they must be decouple...
An international team of more than 300 scientists from 80 institutions has created the first-ever image of the supermassive black hole at the center of our Milky Way galaxy.
Researchers have discovered how to “turn off” a key driver of aortic stenosis – the narrowing of the heart’s aortic valve – identifying for the first time the biological process behind certain instanc...
Study shows loss of gene function is causal to congenital heart disease（图）
loss of gene function causal congenital heart disease
2021/4/9
A team of researchers co-led by Michael Frohman of Stony Brook University has identified an important cause of congenital heart disease. The researchers discovered that certain loss of funct...
Extracellular vesicles (EVs), nanometer-sized messengers that travel between cells to deliver cues and cargo, are promising tools for the next generation of therapies for everything from autoimmune an...

Researchers machine learning predict heart damage COVID-19 victims
2020/6/12
Using machine learning, scientists are working to identify which COVID-19 patients are at risk of adverse cardiac events such as heart failure, sustained abnormal heartbeats, heart attacks, cardiogeni...
Paper is at the heart of an experimental device developed by Rice University bioengineers to study heart disease.They are using paper-based structures that mimic the layered nature of aortic valves, t...

State policies requiring children to attend additional years of school may result in a reduced risk of heart disease and improvements in cardiovascular risk factors in adulthood, according to a study ...
New dinosaur with heart-shaped tail offers clues to evolution of Africa's ecosystems（图）
New dinosaur heart-shaped tail evolution of Africa ecosystems
2019/11/22
A dinosaur that wore its "heart" on its tail is providing new clues to how ecosystems evolved on the African continent during the Cretaceous Period some 100 million years ago, according to researchers...

Heart Monitors Wild Narwhals Alarming Responses Stress
2017/12/19
Narwhals released after entanglement in nets and outfitted with heart monitors performed a series of deep dives, swimming hard to escape, while their heart rates dropped to unexpectedly low levels of ...
Old Faithful is Yellowstone National Park’s most famous landmark. Millions of visitors come to the park every year to see the geyser erupt every 44-125 minutes. But despite Old Faithful’s fame, relati...
