New method advances single-cell transcriptomic technologies

Single-cell transcriptomic methods allow scientists to study thousands of individual cells from living organisms, one-by-one, and sequence each cell's genetic material. Genes are activated differently in each cell type, giving ...

How cellular fingertips may help cells 'speak' to each other

What if you found out that you could heal using only a finger? It sounds like science fiction, reminiscent of the 1982 movie "E.T." Well, it turns out that your body's own cells can do something similarly unexpected. Researchers ...

Widening political rift in U.S. may threaten science, medicine

The lightning speed with which scientists developed and tested the COVID-19 vaccine is a true scientific triumph—one that would not have been possible without the more than 70,000 volunteers who participated in clinical ...

Researchers grow most lifelike bone yet from woven cells

Imagine using stem cells from your bone marrow to grow a piece of bone tissue in the lab, after which medical doctors explore which drugs have the desired effect on your bones. In this way, a tailor-made treatment plan would ...

Graph theory helps biologists study homeostasis

Healthy human bodies are good at regulating: Our temperatures remain around 98.6 degrees Fahrenheit, no matter how hot or cold the temperature around us. The sugar levels in our blood remain fairly constant, even when we ...

Engineers 3-D-print a miniaturized spectrometer

The miniaturization of spectroscopic measurement devices opens novel information channels in medical science and consumer electronics. Scientists of the University of Stuttgart, Germany, developed a 3-D-printed miniature ...

Researchers design next-generation photodetector

Northwestern University researchers have developed a new approach to quantum device design that has produced the first gain-based long-wavelength infrared (LWIR) photodetector using band structure engineering based on a type-II ...
