- ScienceDaily
- 23/3/31 18:06
Researchers have developed a technology for delivering a microrobot to a target point of a hippocampus in an in-vitro environment, connecting neural networks, and measuring neural signals. The findings are expected to contribute to neural network research and the verification and analysis of cell therapy products.
Researchers discover birds with neurotoxin-laden feathers

- 23/3/31 18:06
An expedition into the jungle of New Guinea has resulted in the discovery of two new species of poisonous birds. Genetic changes in these bird species have allowed them to carry a powerful neurotoxin.
Scallop eyes as inspiration for new microscope objectives
- ScienceDaily
- 23/3/31 18:06
Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.
Why are forests turning brown in summer?
- ScienceDaily

European forests are increasingly turning brown in the course of hot, dry summers. In the scorching summer of 2022, Europe experienced more trees turning brown than ever, with 37% of temperate and Mediterranean forest regions affected. In the three-year meteorological history of low-?greenness events, characteristic weather signals can be found as precursors of the events.
At the end of the dry season: Carbon dioxide pulses over Australia
End-of-dry-season CO2 pulses recur each year in the atmosphere above the Australian continent, a discovery made by an international research team led by environmental physicist Prof. Dr. André Butz of Heidelberg University.
Scientists measure laser-heated plasma using Doppler weather forecasting technique
Scientists have used a common weather forecasting technique for insights into how powerful lasers turn hunks of solid material into soups of electrically charged particles known as plasmas.
Connecting distant silicon qubits for scaling up quantum computers
In a demonstration that promises to help scale up quantum computers based on tiny dots of silicon, RIKEN physicists have succeeded in connecting two qubits—the basic unit for quantum information—that are physically distant from one another.
Richard Branson's Virgin Orbit slashing 85% of its workforce
Richard Branson's Virgin Orbit is letting go of almost its entire work force with the satellite launch company finding it difficult to secure funding three months after a failed mission.
NASA-enabled AI predictions may give time to prepare for solar storms
Like a tornado siren for life-threatening storms in America's heartland, a new computer model that combines artificial intelligence (AI) and NASA satellite data could sound the alarm for dangerous space weather.
Researchers elucidate the complexity of flames
A research team, led by Professor Yuji Nakamura of the Department of Mechanical Engineering at Toyohashi University of Technology, discovered that the flickering of flames can be freely controlled by moving two flames closer together or further apart. Until now, it had been known that interference between flames separated by a certain distance causes the flames to flicker during in-phase or...
Imaging technique reveals electronic charges with single-atom resolution
Materials typically conduct electricity or insulate against it—so experimental and theoretical physicists have been captivated by a compound called samarium hexaboride (SmB6) that appears to do both. Numerous studies over the course of 50 years have revealed that SmB6 acts like an insulator as well as an electricity-conducting metal.
Researchers predict a large population of ultra-diffuse local galaxies
Using the most accurate and detailed cosmological simulations available, an international team has made an exciting prediction that may shed new light on our understanding of the universe: a large population of faint galaxies in our cosmic neighborhood await discovery.
Successful visualization of two-dimensional electron gas in high-frequency/power devices
The group led by Professor Naoya Shibata of the University of Tokyo, in collaboration with Sony Group Corporation, succeeded in directly observing a two-dimensional electron gas that accumulated at the semiconductor interface.
Sustainable space exploration will harness microbes
Global warming, pollution and diminishing resources are generating great urgency among scientists seeking solutions by expanding frontiers of exploration and developing new technologies.
Researchers synthesize graphene using intense light
DGIST Professor Yoonkyu Lee's research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible electrode materials and consequently enabling its mass production. The results were published in the February 23 issue of Nano Energy.
Research finds that cKMT1 methylates FNR and regulates energy transfer in cyanobacteria
Cyanobacteria are a diverse group of prokaryotes and the only prokaryotes capable of oxygenic photosynthesis. They exist in a variety of environments and play crucial roles in the global carbon and nitrogen cycles. Synechocystis sp. PCC 6803 (Synechocystis) has been used extensively as a model cyanobacterium for studies concerned with photosynthesis and environmental adaptation.
Researchers suggest metal labeling strategy for single-cell multiplexing with mass cytometry
Researchers from the Suzhou Institute of Biomedical Engineering and Technology (SIBET) of the Chinese Academy of Sciences (CAS) have recently proposed a novel metal labeling strategy to increase the sensitivity of mass cytometry (MC) and expand the number of MC detection channels.
Researchers explore effects of fully relativistic condition on electron cyclotron maser emission
Radio emission, carrying a wealth of information, is critical for understanding the physical process of various outbursts. The electron cyclotron maser emission (ECME) plays an important role as a coherent radiation mechanism in explaining radio emission phenomena from celestial bodies.
Earth's anisotropic inner core structure driven by dipole geomagnetic field, reveals study
A geomagnetic field is generated in Earth's interior and extends into outer space to protect Earth from cosmic radiation and the charged particles of solar wind. The magnetic field is generated by the convection of charged molten iron fluids in Earth's outer core.
Ants took over the world by following flowering plants out of prehistoric forests, says study
Ants are pretty much everywhere. There are more than 14,000 different species, spread over every continent except Antarctica, and researchers have estimated that there are more than four quadrillion individual ants on Earth—that's 4,000,000,000,000,000. But exactly how ants evolved to take over the world is still a mystery.
Moths are more efficient pollinators than bees, shows new research
Moths are more efficient pollinators at night than day-flying pollinators such as bees, finds new research from the University of Sussex, published March 29 in PLOS ONE.
