Investigating robot illusions and simulations of reality

To evaluate the performance of robotics algorithms and controllers, researchers typically use software simulations or real physical robots. While these may appear as two distinct evaluation strategies, there is a whole other ...

Bioengineering organ-specific tissues with high cellular density and embedded vascular channels

Bioengineers study the development of organ-specific tissues in the lab for therapeutic applications. However, the process is highly challenging, since it requires the fabrication and maintenance of dense cellular constructs ...

Programmable swarmbots help make flexible biological tools

Biomedical engineers at Duke University have developed a new platform to create biologic drugs using specially engineered bacteria that burst and release useful proteins when they sense that their capsule is becoming too ...

Earth warming more quickly than thought, new climate models show

Greenhouse gases thrust into the atmosphere mainly by burning fossil fuels are warming Earth's surface more quickly than previously understood, according to new climate models set to replace those used in current UN projections, ...

From primordial black holes new clues to dark matter

Primordial black holes (PBHs) are objects that formed just fractions of a second after the Big Bang, considered by many researchers among the principal candidates in explaining the nature of dark matter, above all following ...

North Atlantic haddock use magnetic compass to guide them

A new study found that the larvae of haddock, a commercially important type of cod, have a magnetic compass to find their way at sea. The findings showed that haddock larvae orient toward the northwest using Earth's magnetic ...

Exercise could slow withering effects of Alzheimer's

Exercising several times a week may delay brain deterioration in people at high risk for Alzheimer's disease, according to a study that scientists say merits further research to establish whether fitness can affect the progression ...

Elusive compounds of greenhouse gas isolated

Nitrous oxide (N2O) is a potent atmospheric pollutant. Although naturally occurring, anthropogenic N2O emissions from intensive agricultural fertilisation, industrial processes, and combustion of fossil fuels and biomass ...

Happy hour for time-resolved crystallography

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg ...

Miniaturizing medical imaging, sensing technology

Scientists in Christine Hendon's and Michal Lipson's research groups at Columbia University, New York, have used a microchip to map the back of the eye for disease diagnosis.

Scientists create fully electronic 2-D spin transistors

Physicists from the University of Groningen constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) ...

A matter of concentration

Plants can grow whole new organs with the help of pluripotent stem cells throughout their entire lives. When necessary, these stem cells can develop into any type of cell within an organism. The biologist Prof. Dr. Thomas ...

A reusable catalyst for the synthesis of esters

A chemist from RUDN University has developed a tin silicate catalyst for the production of esters—flavourings, plasticisers, and biofuel components. Unlike existing catalysts, the new material can be made active again and ...

A safer way for police to test drug evidence

Scientists have demonstrated a way for police to quickly and safely test whether a baggie or other package contains illegal drugs without having to handle any suspicious contents directly. The new technique can limit the ...

NASA-NOAA satellite catches Hurricane Kiko at night

Hurricane Kiko continued to track west through the Eastern Pacific Ocean when NASA-NOAA's Suomi NPP satellite passed overhead and provided a view of the storm. Satellite imagery revealed an elongated shape, which indicated ...

Researchers see need for action on forest fire risk

How do humans affect forest fires? And what can we learn from forest fires in the past for the future of forestry? An international team of researchers led by Elisabeth Dietze, formerly at the German Research Centre for Geosciences ...
