"Twitter has proved a cherished forum for climate scientists to share research, as well as for activists seeking to rally action to halt oil pipelines or decry politicians' failure to cut pollution. But many are now fleeing Twitter due to a surge in climate misinformation, spam and even threats that have upended their relationship with the platform."

"Concerns have been growing about AI's so-called "white guy problem" and now scientists have devised a way to test whether an algorithm is introducing gender or racial biases into decision-making."

"Could we soon send emails 'telepathically'? Scientist transmits message into the mind of a colleague 5,000 miles away using brain waves"

"Going from small data analytics to Big Data analytics or to predictive and prescriptive analytics is trickier. Expanding in both dimensions is human capital intensive, requiring talented data scientists. A McKinsey report (2011) estimates that by 2018, there will be a shortage of 140,000 to 190,000 workers with "deep analytical" experience and a further 1.5 million data-literate managers in the US. Technology giants such as Google, Facebook and Amazon, and large investment banks and top hedge funds can afford such employees, however even now the competition is fierce, as is evidenced by the ongoing talent war in Silicon Valley. The data scientist is indeed a sexy job in the 21st century."

"More than just a poetic metaphor, the butterfly effect says that there are some things that even the most advanced science can never predict. Well, that list of things just got a lot shorter. Scientists from the University of Maryland have used machine learning to predict chaos."

"Computer scientists and machine learning researchers are tackling the pandemic the way they know how: compiling datasets and building algorithms to learn from them."

"Half a century ago, before the first Apple computer was even sold, climate scientists started making computer-generated forecasts of how Earth would warm as carbon emissions saturated the atmosphere (the atmosphere is now brimming with carbon). It turns out these decades-old climate models - which used math equations to predict how much greenhouse gases would heat the planet - were pretty darn accurate. Climate scientists gauged how well early models predicted Earth's relentless warming trend and published their research Wednesday in the journal Geophysical Research Letters."

"Scientists say they can deduce the lifestyle of an individual, down to the kind of grooming products they use, food they eat and medications they take, from chemicals found on the surface of their mobile phone."

"Scientists are fascinated by ant colonies because they can form collectives called "superorganisms" that function as single organisms do. Investigation into how ants behave has revealed more about how such group behavior arises, and some researchers are using that knowledge to help build smarter robot swarms, said Simon Garnier, a scientist who studies animal behavior at the New Jersey Institute of Technology."

"Most AI programs function like a "black box." "We know exactly what a model does but not why it has now specifically recognized that a picture shows a cat," said computer scientist Kristian Kersting of the Technical University of Darmstadt in Germany to the German-language newspaper Handelsblatt. That dilemma prompted Kersting-along with computer scientists Patrick Schramowski of the Technical University of Darmstadt and Björn Deiseroth, Mayukh Deb and Samuel Weinbach, all at the Heidelberg, Germany-based AI company Aleph Alpha-to introduce an algorithm called AtMan earlier this year. AtMan allows large AI systems such as ChatGPT, Dall-E and Midjourney to finally explain their outputs."

"We submitted the grant on time. The next day, while speaking to a friend, I told him, "This week, I wrote my first ChatGPT grant." He replied that he had been doing it for months and that many other scientists are doing the same. A 2023 Nature survey of 1,600 researchers found that more than 25% use AI to help them write manuscripts and that more than 15% use the technology to help them write grant proposals. Some people might see the use of ChatGPT in writing grant proposals as cheating, but it actually highlights a much bigger problem: what is the point of asking scientists to write documents that can be easily created with AI? What value are we adding? Perhaps it is time for funding bodies to rethink their application processes."

"Jack Poulson was a senior research scientist at Google whose work on machine learning work was used to improve Google's search results; now he's quit the company over its Project Dragonfly, a once-secret plan to launch a censored Chinese search engine; Poulson called the move a "forfeiture of our values." Tech companies find it hard to qualify skilled engineers at any price, and machine learning specialists are especially prize, commanding salaries of $1MM/year or more. "

"computer programs can accelerate discovery in the sciences faster than scientists can, if the computer is trained to behave like one"

"A company owned by Google has been given access to the healthcare data of up to 1.6 million patients from three hospitals run by a major London NHS trust. DeepMind, the tech giant's London-based company most famous for its innovative use of artificial intelligence, is being provided with the patient information as part of an agreement with the Royal Free NHS trust, which runs the Barnet, Chase Farm and Royal Free hospitals. It includes information about people who are HIV-positive as well as details of drug overdoses, abortions and patient data from the past five years, according to a report by the New Scientist."

"Five thousand bees will be fitted with the tiny 2.5 mm square RFID chips, which will allow the scientists to track their movements much like a toll tag on your car lets the roadway authority know when you drive past a certain point. Bees tend to fly in regular repeatable patterns, so any changes in their activity will be easy to spot. To tag the bees, they are placed in a refrigerator to make them immobile, then the tags are simply attached with adhesive. The researchers say that the tag has no effect on a bee's behavior, but how would you like to have a big square chip glued to the back of your neck?"

Scientists have developed an app that allows an ordinary smartphone to capture and display three-dimensional models of real-world objects. Instead of taking a normal photograph, a user simply moves the phone around the object of interest and after a few motions, a 3D model appears on the screen.

"Meet GIST, a gesture-controlled wearable device that helps the visually impaired navigate the world around them. University of Nevada computer scientists Vinitha Khambadkar and Eelke Folmer recently debuted GIST at a technology conference."
