Published Fast-charging lithium-sulphur batteries on the horizon
(via sciencedaily.com)
Original source 
New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case.
Published DNA origami-based vaccines toward safe and highly-effective precision cancer immunotherapy
(via sciencedaily.com)
Original source 
Researchers have created a DNA origami platform called DoriVac, whose core component is a self-assembling square block-shaped nanostructure. DoriVac vaccines enabled tumor-bearing mice to better control the growth of tumors and to survive significantly longer than control mice.
Published New research suggests that our universe has no dark matter
(via sciencedaily.com)
Original source 
A new study challenges the current model of the universe by showing that, in fact, it has no room for dark matter.
Published Protein fragments ID two new 'extremophile' microbes--and may help find alien life
(via sciencedaily.com)
Original source 
Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Published Water droplet spun by sound screens for colon cancer
(via sciencedaily.com)
Original source 
Mechanical engineers have devised a diagnostic platform that uses sound waves to spin an individual drop of water up to 6000 revolutions per minute. These speeds separate tiny biological particles within samples placed in a very light disc sitting on top of the spinning drop. The technique could allow new point-of-care applications ranging from precision bioassays to cancer diagnosis. The technique requires less time and sample volume while inflicting less damage to delicate exosomes.
Published New high-speed microscale 3D printing technique
(via sciencedaily.com)
Original source 
A new process for microscale 3D printing creates particles of nearly any shape for applications in medicine, manufacturing, research and more -- at the pace of up to 1 million particles a day.
Published Spiral wrappers switch nanotubes from conductors to semiconductors and back
(via sciencedaily.com)
Original source 
By wrapping a carbon nanotube with a ribbon-like polymer, researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing.
Published Have metalenses expanded their reach into the ultraviolet region?
(via sciencedaily.com)
Original source 
A team achieves successful mass production of metalenses designed for application in the ultraviolet region.
Published Scientists propose new theory that explains sand ripples on Mars and on Earth
(via sciencedaily.com)
Original source 
Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Published Giving particle detectors a boost
(via sciencedaily.com)
Original source 
Researchers have tested the performance of a new device that boosts particle signals.
Published GPS nanoparticle platform precisely delivers therapeutic payload to cancer cells
(via sciencedaily.com)
Original source 
A newly developed 'GPS nanoparticle' injected intravenously can home in on cancer cells to deliver a genetic punch to the protein implicated in tumor growth and spread, according to researchers. They tested their approach in human cell lines and in mice to effectively knock down a cancer-causing gene, reporting that the technique may potentially offer a more precise and effective treatment for notoriously hard-to-treat basal-like breast cancers.
Published Peering into the tendrils of NGC 604 with NASA's Webb
(via sciencedaily.com)
Original source 
The formation of stars and the chaotic environments they inhabit is one of the most well-studied, but also mystery-shrouded, areas of cosmic investigation. The intricacies of these processes are now being unveiled like never before by NASA's James Webb Space Telescope.
Published Breakthrough in nanostructure technology for real-time color display
(via sciencedaily.com)
Original source 
New groundbreaking technology enables the real-time display of colors and shapes through changes in nanostructures.
Published Nasa’s Webb, Hubble telescopes affirm universe’s expansion rate, puzzle persists
(via sciencedaily.com)
Original source 
When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the 'Hubble Tension,' is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe's evolution.
Published Combined microscopy technique catches light-driven polymers in the act
(via sciencedaily.com)
Original source 
Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published CSI in space: Analyzing bloodstain patterns in microgravity
(via sciencedaily.com)
Original source 
As more people seek to go where no man has gone before, researchers are exploring how forensic science can be adapted to extraterrestrial environments. A new study highlights the behavior of blood in microgravity and the unique challenges of bloodstain pattern analysis aboard spacecraft.
Published Interstellar signal linked to aliens was actually just a truck
(via sciencedaily.com)
Original source 
Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
Published Baby quasars: Growing supermassive black holes
(via sciencedaily.com)
Original source 
The James Webb Space Telescope makes one of the most unexpected findings within its first year of service: A high number of faint little red dots in the distant Universe could change the way we understand the genesis of supermassive black holes.
Published Discovery tests theory on cooling of white dwarf stars
(via sciencedaily.com)
Original source 
Open any astronomy textbook to the section on white dwarf stars and you'll likely learn that they are 'dead stars' that continuously cool down over time. Astronomers are challenging this theory after discovering a population of white dwarf stars that stopped cooling for more than eight billion years.
Published New type of nanoparticle makes vaccines more powerful
(via sciencedaily.com)
Original source 
A type of nanoparticle called a metal organic framework (MOF) could be used to deliver vaccines and act as an adjuvant. Researchers find these particles provoke a strong immune response by activating the innate immune system through cell proteins called toll-like receptors.
