Advancing point-of-care diagnostics with an ancient process

With infectious diseases, time is of the essence. Doctors can more easily treat and prevent the spread of diseases such as tuberculosis, Ebola and COVID-19 when they can rapidly and accurately identify new infections. But testing often requires bulky machinery, specialized training and significant capital—all of which can be difficult to find outside of centralized laboratories. Every moment a sample spends in transit, or in a queue at a laboratory, the ability to respond to infectious diseases diminishes.

As molecular diagnostics have developed—most of which rely upon compounds or enzymes suspended in liquid—researchers have been exploring ways to overcome the challenges associated with point-of-care diagnostics. That work did not lead them to a new technique, but an ancient one: freeze-drying, known technically as lyophilization.

Sound beneath the waves

Unlike Space where lightwaves can travel vast distances without being scattered or absorbed, light can only travel short distances in water before it fades from repeated, energy draining collisions with water molecules. As a result, most of Earth’s ocean space exists in darkness, beyond the reach of both light and human exploration. Marine animals have evolved to navigate, communicate, and hunt without light by using sound to illuminate their environment. And, increasingly, humans are doing the same. Here, we’ll briefly explore how sound is being used by animals and humans to render ocean depths visible.

From Gloves to Benches: Recycling Plastic to Improve Biotechnology’s Sustainability

In building towards a greener future, Twist Bioscience has built sustainability into its DNA synthesis platform. Through miniaturized chemistry, Twist enables massive scaling of the DNA synthesis process while also greatly reducing the company’s chemical footprint. But, to truly work towards a sustainable future, laboratories have to go beyond their products to address the challenge of sustainable science.

Dr. Susumu Ohno: Finding the beauty in DNA

It’s an unfortunate reality that science is often viewed as being separate and independent from art. Despite their differences, the two find common ground in their ability to uncover beauty in nature. This commonality shines through in the amazing work of Dr. Susumu Ohno.

Treating Harlem: Dr. May Edward Chinn

Dr. May Edward Chinn was many things: A high school dropout, a talented and successful pianist, the first African-American woman to graduate from Bellevue Hospital Medical College, and, above all else, a dedicated and compassionate physician. Put simply, Dr. Chinn was an inspiring scientist.
