Proteins help organisms form or inhibit ice crystals
Contrary to what you may have been taught, water doesn’t always freeze to ice at 32 degrees F (zero degrees C). Knowing, or controlling, at what temperature water will freeze (starting with a process called nucleation) is critically important to answering questions such as whether or not there will be enough snow on the ski slopes or whether or not it will rain tomorrow.

Forscher entwickeln neue Messmethoden zur Beschreibung von Aerosolteilchen
Luft besteht aus Gasmolekülen und winzigen Teilchen – sogenannten Aerosolen. Der Großteil dieser in der Luft getragenen Teilchen ist nur einige Nanometer groß und nicht sichtbar. Die Detektion und experimentelle Beschreibung dieser Nanoteilchen ist für das Verständnis von klimarelevanten Wolkeneigenschaften und der Bestimmung der Luftqualität von großer Bedeutung und daher ein wesentlicher Aspekt der Aerosolforschung.

AUSTIN, Texas — Engineers at The University of Texas at Austin have developed a new noninvasive technique for simulating repairs to the heart’s mitral valve with levels of accuracy reliable enough for use in a clinical setting. (more…)
People can’t yet be in two places at the same time. But Los Angeles-based musician Julianna Barwick is getting around that little problem to treat guests at a new hotel in New York City to a never-ending, ever-changing, live performance that funnels the sound and mood of the skies above Manhattan down into the lobby.

Forschende zeigen, wie das Immunsystem körpereigene von krankheitserregenden Molekülen unterscheidet
Ein Team um die Freiburger Biologen Prof. Dr. Wolfgang Schamel und Prof. Dr. Wilfried Weber hat in einem Experiment die Dauer der Wechselwirkung eines Proteins mit T-Zellen, weißen Blutkörperchen, kontrolliert und damit gezeigt, wie das Immunsystem krankheitserregende von körpereigenen Molekülen unterscheidet. Die Wissenschaftlerinnen und Wissenschaftler haben die Ergebnisse in der Fachzeitschrift eLife veröffentlicht. (more…)
UD research could aid in prevention of joint injuries from infancy to adulthood
Whether you’re pitching a baseball, playing a violin, or typing at your desk, your shoulder helps you get the job done. This joint is a complex machine, and in order to protect shoulders from injury, scientists want to develop a better understanding of how the most delicate parts of these joints work. (more…)
UCLA psychologists’ experiments demonstrate severe limitations of ‘deep learning’ machines
How smart is the form of artificial intelligence known as deep learning computer networks, and how closely do these machines mimic the human brain? They have improved greatly in recent years, but still have a long way to go, a team of UCLA cognitive psychologists reports in the journal PLOS Computational Biology. (more…)
