"This technique has the potential to provide a low-invasive method of determining if breast cancer is present, as well as the form of breast cancer, without the need to take tissue samples via biopsy," joint-lead author Prof. Fan Zhang from China's Fudan University said. Up until now it...
Costa and her colleagues collected more than 250 tissue samples from common bottlenose dolphins of both groups off Brazil’s coast and analyzed the DNA. The results suggest the dolphins may be going down different evolutionary paths, separating into two species. The genetic analysis found differences...
In each case the steps were similar. Scientists collect tissue samples from museum specimens: the Museums Victoria in Melbourne, Australia, had great Tasmanian tigers, for instance, while the Royal Ontario Museum in Toronto had a nice toe bone from the little bush moa. They then extract DNA. ...
Scientists collecting tissue samples from a Greenland shark. Credit: Ewan Camplisson Wielding such intriguing research results, Camplisson intends to further analyze these sharks' tissues, and their anti-aging metabolisms. It won't just satisfy deep sea biological curiosity. ...
Method The scientists performed experiments using tissue samples from people with COVID-19, as well as cultured human heart and lung cells selected to closely reflect how healthy cells respond to SARS-CoV-2 infection. They observed changes in many genes involved with the Hippo signaling pathway af...
- Microgravity:In space, tissue samples may change when exposed to near weightlessness, and this effect on cryopreserved cells needs more study. Stems cells frozen in nitrogen at -196 C.Credit: BSIP / UIG via Getty Images The great decades-long payoff, however, is that, once stored, the ...
So far, the researchers have used their technique to print out copies of tissue samples, laser-scanned statues, and topographical maps of the Moon. The ability to faithfully reproduce 3D data in a physical form could have a range of applications, from conserving historical artifacts to helping...
Scientists turn organs transparent — and use a new technique to capture 3D pictures of what’s inside The key to tissue clearing lies in changing the way light passes through tissue. Tissue is usually not transparent because light moves through water, lipids, and proteins — the three ...
The researchers also proposed another potential intervention strategy -- the use of plants. Mosquito's gut microbes in the wild are either derived from microbes in breeding waters, or in the sap and nectar of plants. "We are collecting a large number of plant samples in Wenshan, where the ...
Adenoids are unique sentinel immune system tissue that sit at the back of the nasal passages, just above the top of the throat. They sample the air we breathe and are home to germinal centers, which produce disease-fighting B cells that make antibodies. Adenoids are known to shrink in ...
