In the largest study performed to date to understand the relationship between habitual physical activity and physical fitness, researchers have found that higher amount of time spent performing exercise (moderate-vigorous physical activity) and low-mod…

Sand and gravel are the most mined materials in the world, with between 32 and 50 billion tons extracted globally each year. They are being extracted faster than they can be replaced. But according to a new study, the human and environmental costs of t…

The importance of the root system for agricultural yields is often underestimated. Whether roots can access water and nutrients effectively also determines the resilience of important crops to drought and climate change. Researchers have discovered and…

How to design efficient demo areas for urban carbon sequestration? In the latest policy brief research groups focus on the main principles of urban demonstration areas using biochars for carbon sequestration.

Scientists have discovered that the mass and size of nano-particles can be simultaneously measured by passing the nanoparticles, in their native solution, through an inexpensive and simple mechanical tube.

Linked Weyl surfaces, a novel type of topological phase that exists in five-dimensional space, have now been experimentally observed. The work provides a unique platform for exploring various topological phases, the transition between them, and the cor…

Roe deer are among the few mammals whose embryos go into a particularly long period of dormancy. Using modern molecular methods, researchers have shown for the first time what exactly happens in the embryo during this phase. They have identified signal…

New guidelines for the diagnosis and treatment of acute and chronic heart failure have just been published. Approximately 2% of adults worldwide have heart failure. Prevalence increases with age, from 1% in those under 55 years to more than 10% in peop…

Academics have been monitoring the Lyme Bay Marine Protected area using underwater cameras and other techniques since 2008, but this is the first known study to examine an MPA’s response and resilience in the face of extreme storms.

Around 650 million years ago, the Earth entered into the Marinoan glaciation that saw the entire planet freeze. The ‘Snowball Earth’ impeded the evolution of life. But as it warmed, biotic life began to flourish. A research team has now analyzed rock s…

Using a supercomputer simulation, a research team has succeeded in following the development of a galaxy over a span of 13.8 billion years. The study shows how, due to interstellar frontal collisions, young and chaotic galaxies over time mature into sp…

Researchers have found that while playing musical instruments can emit the same levels of potentially COVID-laden airborne particles as singing, simple safety measures, such as masking instruments, social distancing and implementing time limits, signif…

A baby born prematurely often has to be separated from its parents and placed in an incubator in intensive care. For several weeks, he or she will undergo routine medical procedures that can be painful, without being relieved by too many pharmaceutical…

Cutting 20% of sugar from packaged foods and 40% from beverages could prevent 2.48 million cardiovascular disease events (such as strokes, heart attacks, cardiac arrests), 490,000 cardiovascular deaths, and 750,000 diabetes cases in the U.S. over the l…

A feasibility study has found that drones can be used to deliver life-saving defibrillators to people with suspected cardiac arrest in the community.

A ‘humanized’ mouse model equipped with the immune system of a patient who needs an organ transplant beats current measures for identifying the best potential living donor, scientists report.

Brown dwarfs are astronomical objects with masses between those of planets and stars. The question of where exactly the limits of their mass lie remains a matter of debate, especially since their constitution is very similar to that of low-mass stars. …

New research reveals that neurons in the visual cortex — the part of the brain that processes visual stimuli — change their responses to the same stimulus over time. Although other studies have documented ‘representational drift’ in neurons in the pa…
