How Do Hummingbirds Find Feeders Quickly ? 10 Ways

Paper Blog 

Curious about the remarkable ability of how do hummingbirds find feeders in seemingly remote areas? Despite their tiny size, these incredible birds possess an astonishing sense of direction and an uncanny knack for finding food sources, even in the middle of nowhere. Understanding the mechanisms behind this remarkable feat can shed light on the fascinating …

Researchers offer insights into solid-electrolyte interphases in next-gen aqueous potassium-ion batteries

Sciencedaily.com 

Aqueous potassium-ion batteries are a promising alternative to lithium-ion batteries owing to their safety and low cost. However, not much is known about the properties of the solid-electrolyte interphases (SEI) that form between the electrode and the aqueous electrolyte. To address this knowledge gap, researchers from Japan have now conducted a study using advanced scanning electrochemical microscopy and operando electrochemical mass spectrometry. Their findings provide a deeper understanding of SEI in next-generation batteries.

Novel ligands for transition-metal catalysis of photoreactions

Sciencedaily.com 

Transition metals exchange electrons with supporting ligands to form complexes that facilitate reaction catalysis in several industries, like pharmaceutical production. Both the metal center and the ligand moiety have pivotal roles in enabling catalysis. While numerous transition metal-catalyzed photoreactions have been developed, only a few new ligands have been reported. Researchers from Chiba University have now developed novel ligands to create transition metal complexes, defining new reaction capabilities.

Laser-based ice-core sampling for studying climate change

Sciencedaily.com 

Researchers have developed a new laser-based sampling system for studying the composition of ice cores taken from glaciers. The new system has a 3-mm depth-resolution and is expected to help reconstruct continuous annual temperature changes that occurred thousands to hundreds of thousands of years ago, which will help scientists understand climate change in the past and present.



Combustion powers bug-sized robots to leap, lift and race

Sciencedaily.com 

Researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors.

How wind turbines react to turbulence

Sciencedaily.com 

The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.

Scientists develop method to detect deadly infectious diseases

Sciencedaily.com 

Researchers have developed a way of detecting the early onset of deadly infectious diseases using a test so ultrasensitive that it could someday revolutionize medical approaches to epidemics. The test is an electronic sensor contained within a computer chip. It employs nanoballs -- microscopic spherical clumps made of tinier particles of genetic material -- and combines that technology with advanced electronics.

Assessing unintended consequences in AI-based neurosurgical training

Sciencedaily.com 

A new study shows that human instruction is still necessary to detect and compensate for unintended, and sometimes negative, changes in neurosurgeon behavior after virtual reality AI training. This finding has implications for other fields of training.

Study finds two antibiotics for children with sinusitis equally effective, but one had fewer side effects

Sciencedaily.com 

Acute sinusitis is one of the most common causes for children to be put on antibiotic medications, with patients in the United States filing nearly 5 million antibiotic prescriptions every year to treat the condition. The drugs amoxicillin and amoxicillin-clavulanate make up most of those prescriptions, but there is a lack of consensus on which should be first-line for children.
