Our climate future depends on the choices we make now.IPCC 2023, 6th Assessment Report As has been widely reported, 2023 was officially the hottest year on record. For the last twelve months they have exceeded 1.5°C above pre-industrial levels (the scientific base period used for global warming). That bleak milestone has led some critics to say that reaching net zero carbon dioxide emissions by 2050 is impossible. Doomsayers even claim that it is too late to stop climate change. Fortunately, science and economics show that these narratives are completely wrong. However, they are dangerous because of the regression and inertia…

Robot and young woman face to face.getty Artificial Intelligence, or AI, is like a highly specialized tool in an enterprise environment, capable of performing specific tasks such as analyzing data, predicting patterns, or automating routine processes. This isn’t new and has been around for a while – after all, wasn’t Netflix recommending content for us to use AI to watch almost a decade ago? Generative Artificial Intelligence, or GenAI, on the other hand, is a subset of AI and is relatively newer. It can create new content, such as creating an image or drawing, using its programming to “imagine” and…

The Perseverance Mars rover’s robotic arm houses the SHERLOC instrument. NASA/JPL-Caltech/ASU/MSSS It can be quite difficult to fix a technical problem on Earth. NASA’s Perseverance Mars rover team is trying to fix a technical problem with a robot on another planet. There is an attached dust cover on an important instrument that helps the rover search for organic compounds. It puts a crimp in some of the rover’s science functions. The SHERLOC instrument has a long official name: Raman & Luminescence Scanning of Habitable Environments for Organics and Chemicals. SHERLOC is mounted on the rover’s robotic arm and includes cameras,…

Studio shot of a group of business people looking bored while waiting in line against a gray … [+] Recordgetty A traditional metric for calculating how many employees you need is revenue per employee. But the measurement is very different between industries. Companies that sell software, for example, don’t need as many employees as people that sell consulting services. But in general, do most companies really need all the paid employees? The premise here is that they don’t, and that traditional revenue/employee metrics are irrelevant to productivity and profitability if companies are willing to take an objectively hard look at…

Sonoran desert toads use a fascinating defense mechanism against predators – hallucinogenic toxins. … [+] But nature has found a way to overcome it.getty Amphibians are extremely hardy creatures. In their 300 million years of existence, they have survived mass extinctions, ecological upheavals and persistent threats from predators – which include human demand for their psychedelic compound. In the process of evolution, many amphibians, such as toads, have developed strange but highly effective defense mechanisms against predators. Some are brightly colored to warn other animals of their toxicity, a strategy known as de-marking. However, others, such as the Sonoran Desert…

The top row Emergency medical services in rural areas are less likely to relieve pain in trauma patients who provide proper care to children with asthma attacks and are more likely to use lights and sirens unnecessarily, according to a study published Tuesday, adding to previous research found rural health systems struggle more compared to urban and suburban areas. An ambulance responds to the emergency scene.getty Basic elements The team of researchers from the Icahn School of Medicine of Mount Sinai reviewed all 911 dispatches in the US in 2019 – which consisted of more than 6 million responses from…

But over time, as technology has improved, we’ve gotten better at collecting and analyzing data. Much better. In response, a new approach to understanding complex phenomena—a new discipline, really—has begun to take off. This discipline is called complexity science.When faced with a complex problem—like how the oceans will respond to climate change, or how the neurons in our brains communicate with each other, or how traffic could best be routed in a rapidly growing city—complexity science encourages a holistic view. Instead of breaking the problem into tiny parts and studying each one separately, you can analyze the system as a…
