Scope 3 Carbon Emissions and the Management of Supply Chains – State of the Planet

When measuring and managing an organization’s production of pollution, it is not enough to reduce the emissions you produce directly, you must also reduce the pollution created by your suppliers. In the language of greenhouse gas pollution, these are called Scope 3 emissions. Scope 1 emissions are those directly caused by your organization, for example, the emissions from motor vehicles owned by your organization. Scope 2 emissions are those emissions caused indirectly, for example, by the utility that supplies your electricity. Scope 3 emissions are emissions from the organizations you contract with for services or supplies. A growing area of my study of organizations has been an effort to understand the management of organizations and people who are not under direct hierarchical control...

AI noise-cancelling headphones let you focus on just one voice

Selectively cutting out some external noises could leave you hearing only the sounds you wantCavan Images/Alamy Prototype noise-cancelling headphones allow you to select which background noises to drown out, letting you put an “audio spotlight” on one specific voice so you can concentrate on it. Conventional noise-cancelling headphones reduce unwanted sounds like the rumble of a bus engine, but because the technology cancels out certain frequencies entirely, it can also suppress sounds we want to hear. Now, Shyam Gollakota at the University of Washington in Seattle and his colleagues have created headphones that can remove any unwanted noises while leaving others intact, regardless of their frequencies. It can also be trained with the press of a button to home in...

Doughnut-shaped swirls of laser light can be used to transmit images

Smoke rings are similar to the vortices created in laser lightYevhen Rychko / Alamy Stock Photo Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar swirling structures can also be made to form in beams of light. One such structure is a vortex ring, in which particles of light – or photons – twist and swirl like particles of air do in a smoke ring. Jinping Yao at the Chinese Academy of Sciences and her colleagues have now worked out how to pack up to 28 vortex rings into one laser pulse. To do so, the team precisely tailored the light’s intensity, and tweaked another property of light called phase. Light is an electroma...

How Can ESG Support Female Leadership? – State of the Planet

Credit: Christina @wocintechchat.com, Unsplash ESG adoption has been on a sharp rise, and so has criticism of it. ESG—which stands for environment, social and governance—is a framework used to assess a company’s impact on society and the environment, helping investors and stakeholders evaluate its sustainability and ethical practices. As global awareness of sustainability and responsible business practices continues to grow, ESG has become a pivotal tool for assessing how well companies align with ethical, human capital and environmental considerations, while also laying the foundation for businesses to take sustainability beyond marketing. As of Feb 2024, more than 90% of S&P 500 companies reported on ESG, indicating that adoption of its precepts is more than just a trend. ...

DeepMind is experimenting with a nearly indestructible robot hand

The Shadow Hand robotic device was built to withstand collision damageShadow Robot Company A new robot hand provides extremely fast and flexible finger movements, while also being tough enough to survive intense damage. That durability helps the hand, which is already being used in Google DeepMind’s robotics experiments, during the trial-and-error learning required to train artificial intelligence. This latest robotic hand developed by the UK-based Shadow Robot Company can go from fully open to closed within 500 milliseconds and perform a fingertip pinch with up to 10 newtons of force. It can also withstand repeated punishment such as pistons punching the fingers from multiple angles or a person smashing the device with a hammer. The new hand’s robust design is w...
