The direction of movement of a microbe directly depends on the curvature of its environment, according to new findings. The researchers investigated the navigation of a model microbe, a small self-propelling microalga, in confined compartments with different shapes. They also developed theoretical models to predict the probability flux of that microswimmer which was confirmed by experiments. With...
Researchers have developed a time-domain single-pixel imaging technique to speed the measurement of ultrafast pulses in infrared and far infrared wavelengths.
The debate on green vehicles often focuses on fuel efficiency and alternative fuels, with the transition to fuel alternatives commonly being considered better for the environment the faster it is. A new study shows that keeping and using existing fuel-efficient cars a little longer can actually reduce CO? emissions even with gasoline cars. Thus, a gradual transition and policies that encourage a...
In 2020, an estimated 10 million people lost their lives to cancer. This devastating disease is underpinned by changes to our DNA – the instruction manual for all our cells.
The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles' origins remain unexplained.
Researchers have identified a protein that may critically contribute to severe forms of COVID-19.
The discovery provides a new causal explanation for 1-2% of adults with the condition.
An international research team uses topological platform to demonstrate coherent array of vertical lasers.
An observational study confirms a prevailing theory that volatile organic compounds emitted by vegetation form atmospheric aerosols which make clouds more reflective.
New research suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure.
Machine learning can pinpoint 'genes of importance' that help crops to grow with less fertilizer, according to a new study. It can also predict additional traits in plants and disease outcomes in animals, illustrating its applications beyond agriculture.
An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments.
Scientists offer an alternative way to understand and minimize health impacts from human-caused changes to the climate and environment.
In a preclinical study show that their small molecule drug, SRI-42127, can potently attenuate the triggers of neuroinflammation. These experiments in glial cell cultures and mice now open the door to testing SRI-42127 in models of acute and chronic neurological injury.
People are more aware of the plight of endangered gorillas than of gorillas' gut worms, and are understandably more enamored with mouse lemurs than their mites. Half of the world's roughly 500 primate species are at risk of extinction due to human activities such as hunting, trapping and deforestation. But the demise of the world's threatened primates could also trigger even more extinctions for...
Researchers have developed a new way of determining the age of a lobster based on its DNA. Lobsters are notoriously difficult to age. Nobody knows exactly how old they can get, and some experts have estimated they could live on the ocean floor for as long as a century or more. Until now, a lobster's age has usually been estimated using its size - but this is inaccurate as individual lobsters grow...
