Uncovering fragmentation differences in chiral biomolecules

By combining mass spectroscopy with further analytical and simulation techniques, researchers have revealed key differences in the fragmentation of dipeptide biomolecules with different chiral structures.

Emergent magnetic monopoles controlled at room temperature

Three dimensional (3D) nano-networks promise a new era in modern solid state physics with numerous applications in photonics, bio-medicine, and spintronics. The realization of 3D magnetic nano-architectures could enable ultra-fast and low-energy data storage devices. Due to competing magnetic interactions in these systems, magnetic charges or magnetic monopoles can emerge, which can be utilized as mobile, binary information carriers. Researchers at University of Vienna have now designed the first 3D artificial spin ice lattice hosting unbound magnetic charges. The results published in the journal npj Computational Materials present a first theoretical demonstration that, in the new lattice, the magnetic monopoles are stable at room temperature and can be steered on-demand by external magnetic fields.

Novel molecular imaging technique casts complex coordination molecules in a new light

High-angle annular dark-field scanning transmission electron microscopy can be used to determine complex conformational structures of both crystalline and amorphous polynuclear non-planar coordination molecules, as shown by scientists from Tokyo Institute of Technology (Tokyo Tech). Using iridium as a tracer metal, they were successful in determining the different conformations of a highly branched coordination compound molecule. This has opened up possibilities for imaging and designing of complex inorganic and organic molecules.

'Seeing' single cells with sound

If you are a researcher who wants to see how just a few cells in an organism are behaving, it is no simple task. The human body contains approximately 37 trillion cells; the fruit fly flitting around the overripe bananas on your counter might have 50,000 cells. Even Caenorhabditis elegans, a tiny worm commonly used in biological research, can have as many as 3,000 cells. So, how do you monitor a couple of microscopic specks amid all of that?

Revisiting Clebsch's early papers on the flow of incompressible fluids

New analysis of two recently translated papers, first published in the 1850s, assesses the early methods used by Alfred Clebsch to describe the flow of incompressible fluids, and explores their impact on active areas of cutting-edge research

Using particle accelerators to investigate the quark-gluon plasma of the infant universe

In the early stages of the Universe, quarks and gluons were quickly confined to protons and neutrons which went on to form atoms. With particle accelerators reaching increasingly higher energy levels the opportunity to study this fleeting primordial state of matter has finally arrived.

Astronomy and Space news

Humans could recolonize Earth after mass extinctions with ectogenesis

Lately it seems that every movie, book and video game we see is about future apocalypses. Science articles are also painting a grim future for Earth and its inhabitants. If it's not global warming that will get us, it will be nuclear weapons, pandemics or AI gone rogue. Even if we could overcome such threats, we must still contend with the many natural forces that have caused mass extinctions in the past. Could we actually divert the asteroids, squelch volcanic upheavals and find oases of food and warmth deep enough to survive severe ice ages? Despite the heroics that we see in disaster movies, the answers to these questions are more likely to be no, no and no.

NASA Mars rover begins collecting rock in search of alien life

NASA's Perseverance rover has begun drilling into the surface of Mars and will collect rock samples to be picked up by future missions for analysis by scientists on Earth.

Observatory in Chile takes highest-resolution measurements of asteroid surface temperatures ever obtained from earth

A close examination of the millimeter-wavelength emissions from the asteroid Psyche, which NASA intends to visit in 2026, has produced the first temperature map of the object, providing new insight into its surface properties. The findings, described in a paper published in Planetary Science Journal (PSJ) on August 5, are a step toward resolving the mystery of the origin of this unusual object, which has been thought by some to be a chunk of the core of an ill-fated protoplanet.

Virgin Galactic restarts space-trip sales at $450,000 and up

The ticket window is open again for space flights at Virgin Galactic, with prices starting at $450,000 a seat.

Study reveals an increase in the frequency of nuclear power outages caused by climate change

Past research suggests that climate change and energy systems have a bidirectional relationship. In other words, just like emissions from energy systems can fuel climate change, climate change could also expose the vulnerabilities or shortcomings of energy systems.

Speed and absorption key to optimizing a new type of rechargeable battery

Rechargeable batteries are a necessity to meet the world's growing energy demands in a sustainable fashion, but not all are equal. Researchers in the Energy Materials and Surface Sciences Unit at the Okinawa Institute of Science and Technology Graduate University have worked to optimize a promising candidate of such energy sources—lithium sulfur batteries. The study was published in Nature Communications.

Doubling the performance of visual recognition AI

Prof. Sunghoon Im, from the Department of Information & Communication Engineering, DGIST, developed an artificial intelligence(AI) neural network module that can separate and convert environmental information in the form of complex images using deep learning. The developed network is expected to significantly contribute to the future advancement in the field of AI, including image conversion and domain adaptation.

Reimagining an iconic design class for remote learning

For the past 50 years, mechanical engineering students at MIT have convened on campus for a boisterous robot competition. Since the 1970s, when the late Professor Emeritus Woodie Flowers first challenged students to build a machine using a "kit of junk," students in class 2.007 (Design and Manufacturing I) have designed and built their own robots to compete in the class's final robot competition. For many students, the class and competition are a driving factor in their decision to enroll in MIT.

Startups, researchers race in the Wild West of electric vehicle battery recycling

Electric vehicles are expected to take off dramatically in the coming years. They'll be followed, eventually, by a wave of used batteries that—as it stands now—will be headed mostly for landfills.
