Every human and natural system — from oil extraction to the flight of a flock of starlings — can be seen as a set of repeating patterns. These patterns can be disrupted for good or for bad, says Nigel Topping, the High Level Climate Action Champion for COP26, the UN's climate change conference set to take place in November 2021 in Glasgow, Scotland. He shares three rules of radical collaboration
A new startup is claiming it can deliver a dramatic improvement over existing battery designs. Stories like this often elicit rightful skepticism from readers. While battery technology absolutely improves over time, virtually all of that improvement comes from enhancements to existing Li-ion chemistry rather than brand-new ideas. That's actually one reason why this announcement might lead to some
There is an urgent need to develop and implement effective screening, diagnosis and treatment strategies for patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), common liver conditions with a rising burden in the U.S. and globally. This is particularly important for the most at-risk patients, those with diabetes and obesity.
Research published in the International Journal of Product Lifecycle Management has looked at the concept of obsolescence. A. Sánchez-Carralero and C. Armenta-Déu of the Universidad Complutense de Madrid in Spain explain how they have developed a model to simulate the obsolescence process that leads to the need to replace durable goods.
A research team at the University of Cadiz (Spain), together with researchers from the University of Aveiro (Portugal) from the research group Biopol4fun, have developed a bioactive or functionalised plastic made from nanofibrillated cellulose and mango leaf extracts that preserves food longer than non-functionalised plastics.

Anthropogenic climate change is already affecting the marine plankton populations present in the western Mediterranean Sea. This is the result of a study led by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) thatwarns on the increasing surface ocean temperature lowering organic matter production (primary production), which has negative imp
The return of wolves to Yellowstone National Park in 1995 popularized the idea of reintroducing long-lost species to modern habitats. While scientists are still trying to fully understand the ecological consequences, the wolf's reintroduction likely benefited other species, illustrating how conservation can not just slow biodiversity loss, but even reverse it.
Researchers have documented an entirely new class of fire, spherical cool diffusion flames, appropriately referred to as "cool flames." Creating this unique fire required an equally unique laboratory: the microgravity environment of space. Researchers documented these dim, quiet flames aboard the International Space Station. "The Space Station is a lab like no other," says Richard Axelbaum , prof
The Paris Agreement adopted a target for global warming not to exceed 1.5°C. This sets a limit on the additional carbon we can add to the atmosphere—the carbon budget. Only around 17% of the carbon budget is now left. That is about 10 years at current emission rates.

Scientists around the world are collaborating on a project that is changing the way they trace the evolutionary history of flowering plants. By using new technology allowing them to rapidly retrieve and compare DNA sequences from among any of the 300,000 species of flowering plants, scientists are unraveling the 140-million-year history of the largest group of land plants on Earth and providing a
An impossible standard is at the root of gender inequalities in the workplace, according to two new studies on inflexibility and discrimination against mothers. Put simply: Working mothers are often expected to work like they don't have children and raise children as if they don't work. The research papers, published separately ( first , second ) in Demography , demonstrate how inflexible schedul
Hubble has been orbiting Earth for decades, capturing incredible images of the cosmos that aren't possible with other instruments. That's not because Hubble is the biggest, and it's certainly lacking in modern technology. Hubble is unmatched because of where it is, far above Earth's murky atmosphere. A new project from Durham University, Princeton University, NASA, and others envisions a cheaper
There's one reason that businesses use software suites from Microsoft and Google to facilitate their work: simplicity. These companies allow users to toggle between different apps for email, video chat, documents and more, which lets a workplace conduct all of its work in one place. Well, not exactly. If, for example, you're looking to collect various documents and correspondences for a recent hi
Mark Zuckerberg has revealed that he plans to transition Facebook from a social media company to one that build and manages an immersive virtual reality "metaverse". The idea sounds a lot like Oasis from Ready Player One . The term itself was coined in the 1992 science fiction novel, Snow Crash , by Neal Stephenson. The basic idea is of a joining of physical, virtual, and augmented reality into o

I just watched a documentary about artificial hearts. The old school designs try to mimic an actual heart, and they've gotten pretty polished over the years, but they have a fundamental problem. The mechanical components wear out really fast when you have a membrane that's constantly flexing, so even the best ones only last a few years. One guy came up with a version that basically lasts forever
