New study allows scientists to test therapies for rare neurodegenerative disease affecting young children

In this image of a human STEM cell derived neuron, the Trk-fused gene protein (TFG) is shown in green and the Golgi Apparatus, the organelle which helps package proteins for transport to the rest of the body, is shown in red.

NASA’s DART asteroid mission is a rare opportunity for scientists

Before NASA’s planetary defense probe DART self-destructs by slamming into the asteroid Dimorphos next week, it will offer views of only the sixth asteroid we will have ever seen up close. Scientists are eager to get their hands on those images, as they admit that we know extremely little about the space rocks potentially threatening … Read more

Scientists use modified silk proteins to create new nonstick surfaces

ChemBioChem (2022). DOI: 10.1002/cbic.202200429″ width=”800″ height=”435″/> Graphical abstract. Credit: ChemBioChem (2022). DOI: 10.1002/cbic.202200429 Researchers at Tufts University have developed a method to make silk-based materials that refuse to stick to water, or almost anything else containing water for that matter. In fact, the modified silk, which can be molded into forms like plastic, or coated … Read more

Scientists chip away at the mystery of how radiation weakens metal, one atom at a time

Ocean scientists measure sediment plume stirred up by deep-sea-mining vehicle

Credit: Unsplash/CC0 Public Domain What will be the impact to the ocean if humans are to mine the deep sea? It’s a question that’s gaining urgency as interest in marine minerals has grown. The ocean’s deep-sea bed is scattered with ancient, potato-sized rocks “polymetallic nodules” that contain nickel and cobalt—minerals that are in high demand … Read more

Scientists engineer mosquitoes that can’t spread malaria

Professor George Christophides holds a cage of mosquitoes. Credit: Imperial College London Scientists have engineered mosquitoes that slow the growth of malaria-causing parasites in their gut, preventing transmission of the disease to humans. The genetic modification mosquitoes to produce compounds in their guts that stunt the growth of parasites, meaning they are unlikely to reach … Read more

New method allows scientists to determine all the molecules present in the lysosomes of mice

A cartoon representation of the new method, which allows scientists to isolate the lysosomes (left) of any cell in a mouse to analyze and identify using mass spectrometry (right) all the molecules inside them.

For microorganisms, apparently a lot. Prokaryotes are single-celled microorganisms—bacteria are an example—that are abundant the world over. They exist in the oceans, in soils, in extreme environments like hot springs, and even … Read more

A baby fossil helped scientists explain how mammals thrived after the dinosaur extinction

An artist’s impression of the Pantolambda bathmodon. Credit: H Sharpe, Author provided Sixty-two million years ago, a mother gave birth to a baby. Overcoming the shock of birth in a matter of minutes, the baby began to explore the world around it. The baby started to suckle from its mother, a natural instinct shared by … Read more

A new holographic microscope allows scientists to see through the skull and image the mouse brain
