Jun 15, 2022 (Nanowerk News) Astronomers at MIT and elsewhere have discovered a new multiplanet system within our galactic neighborhood that lies just 10 parsecs, or about 33 light-years, from Earth, making it one of the closest known multiplanet systems to our own. At the heart of the system lies...
Functionalizing van der Waals materials by shaping them
Jun 15, 2022 (Nanowerk News) PN junction is the elementary building block of semiconductor devices, like diode, solar cell and LED, which make up the modern (opto-)electronics. Recently, researchers from the Shanghai Institute of Technical Physics of the Chinese Academy of Sciences have proposed a novel method to fabricate two-dimensional...
Origami millirobots bring health care closer to precision drug delivery
Jun 15, 2022 (Nanowerk News) If you’ve ever swallowed the same round tablet in hopes of curing everything from stomach cramps to headaches, you already know that medicines aren’t always designed to treat precise pain points. While over-the-counter pills have cured many ailments for decades, biomedical researchers have only recently...
Millisecond pulsars can explain the gamma-ray excess in the Milky Way center
Jun 13, 2022 (Nanowerk News) Old and fast spinning neutron stars called millisecond pulsars could be responsible for an unexplained signal from the center of our Milky Way, reports a team of astrophysicists in a new study published in Nature Astronomy ("Millisecond pulsars from accretion-induced collapse as the origin of...
Real-time imaging of dynamic atom-atom interactions
Jun 14, 2022 (Nanowerk News) In a breakthrough, Tokyo Tech researchers have managed to observe and characterize dynamic assembly of metallic atoms using an ingenious combination of scanning transmission electron microscopy and a video-based tracking (Nature Communications, "Dynamic hetero-metallic bondings visualized by sequential atom imaging"). By visualizing short-lived molecules, such...
Scientists create nanoparticle that helps fight solid tumors
Jun 14, 2022 (Nanowerk News) Researchers from Wake Forest University School of Medicine have discovered a possible new approach in treating solid tumors through the creation of a novel nanoparticle. Solid tumors are found in cancers such as breast, head and neck, and colon cancer. In the study, Xin Ming,...
Scientists on the hunt for planetary formation fossils reveal unexpected eccentricities in nearby debris disk
Jun 14, 2022 (Nanowerk News) Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists expected ALMA to confirm the debris...
New, highly tunable composite materials
Jun 14, 2022 (Nanowerk News) Watch for the patterns created as the circles move across each other. Those patterns, created by two sets of lines offset from each other, are called moiré (pronounced mwar-AY) effects. As optical illusions, moiré patterns create neat simulations of movement. But at the atomic scale,...
DNA nanotech safe for medical use, new study suggests
Jun 14, 2022 (Nanowerk News) Advances in nanotechnology have made it possible to fabricate structures out of DNA for use in biomedical applications like delivering drugs or creating vaccines, but new research in mice investigates the safety of the technology. Using a technique called DNA Origami (DO) – a process...
Participants wanted for study on the regulation of what future AI-driven nanomedicines should look like
Jun 14, 2022 (Nanowerk News) Would you like to help in some research on the regulation of what future AI-driven nanomedicines should look like? If so, researchers at the University of Bristol are looking for volunteers to discuss ethical and regulatory issues of using AI driven cancer therapies with swarm...
