NASA TV to Air International Space Station Crew Landing

Three residents of the International Space Station, including one NASA astronaut, are scheduled to wrap up their stay aboard the orbital laboratory Wednesday, Dec. 19.

Shrinking objects to the nanoscale

Researchers have invented a new way to fabricate nanoscale 3D objects of nearly any shape. They can also pattern the objects with a variety of useful materials, including metals, semiconducting quantum dots, and DNA.

Machine learning to speed chemical discoveries, reduce waste

Researchers have combined artificial neural networks with infrared thermal imaging to control and interpret chemical reactions with new precision and speed. Novel microreactors allow chemical discoveries to take place quickly and with far less environmental waste than standard large-scale reactions. The system can reduce the decision-making process about certain chemical manufacturing processes from one year to a matter of weeks, saving tons of chemical waste and energy in the process.

Tangled magnetic fields power cosmic particle accelerators

Magnetic field lines tangled like spaghetti in a bowl might be behind the most powerful particle accelerators in the universe. That's the result of a new computational study that simulated particle emissions from distant active galaxies.

How particles arrange themselves into complex structures

Complexity in nature, whether in chlorophyll or in living organisms, often results from self-assembly and is considered particularly robust. Compact clusters of elemental particles can be shown to be of practical relevance, and are found in atomic nuclei, nano particles or viruses. Researchers have decoded the structure and the process behind the formation of one class of such highly ordered clusters. Their findings have increased understanding of how structures are formed in clusters.

New discovery improves use of optical tweezers

This year's Nobel Prize in Physics, awarded for discoveries in laser physics, recognizes optical tweezers. Now researchers have developed a method that greatly simplifies and improves the use of optical tweezers.

Researchers lay foundation for smart contrast medium

Molecular imaging techniques are playing an increasingly important role in medical diagnostics and developing new treatment methods. An interdisciplinary team of researchers from the fields of chemistry, material sciences, biomedicine, quantum physics and toxicology has managed to develop the foundations for a novel contrast medium for MRI in the framework of the FET Open EU excellence programme. Molecular changes in the human body could thus become detectable by MRI and improve and elucidate the treatment of diseases such as cancer, Alzheimer's and heart diseases.

The secret life of cloud droplets

Do water droplets cluster inside clouds? Researchers confirm two decades of theory with an airborne imaging instrument.

Time travel is possible – but only if you have an object with infinite mass

The concept of time travel has always captured the imagination of physicists and laypersons alike. But is it really possible? Of course it is. We're doing it right now, aren't we? We are all traveling into the future one second at a time.

Novel X-ray imaging technique provides nanoscale insights into behavior of biological molecules

Berkeley Lab researchers, in collaboration with scientists from SLAC National Accelerator Laboratory and the Max Planck Institute, have demonstrated that fluctuation X-ray scattering is capable of capturing the behavior of biological systems in unprecedented detail.
