The artificial intelligence learned using video and audio from a helmet-mounted camera worn by Sam — here aged 18 months.Credit: Wai Keen Vong An artificial intelligence (AI) model has learnt to recognize words such as ‘crib’ and ‘ball’, by studying headcam recordings of a tiny fraction of a single baby’s life. The results suggest that…

Abstract September 2023 was the warmest September on record globally by a record margin of 0.5 °C. Here we show that such a record-breaking margin is an extremely rare event in the latest generation of climate models, making it highly unlikely (p ~ 1%) that internal climate variability combined with the steady increase in greenhouse gas forcing could…

Abstract A small chlorite vial, discovered among numerous artifacts looted and recovered in the Jiroft region of Kerman province, southeastern Iran, contains a deep red cosmetic preparation that is likely a lip-coloring paint or paste. Through analytical research involving XRD (X-ray diffraction), SEM–EDS (scanning electron microscopy-energy-dispersive spectroscopy), and HPLC–MS (high-performance liquid chromatography-mass spectrometry) analyses, the…

Abstract The local quality of super-resolution microscopy images can be assessed and mapped by rolling Fourier ring correlation, even when image quality varies within a single image. Super-resolution fluorescence microscopy—recognized by the 2014 Nobel Prize—has allowed researchers to visualize biological structures and beyond in exquisite detail. As super-resolution microscopy has become more widely adopted, variations…

Dry January. The Kashmir Valley is a popular winter tourist destination owing to its mountains and ski resorts — such as Gulmarg, pictured here, where the hills are normally snow-covered in January. But the valley has been afflicted by an exceptional drought, with no snow and an almost 80% shortfall in rain between December 2023…

Innovations such as remotely operated robotic surgery are coming, but people have concerns about governments’ competence to regulate new technologies.Credit: CFOTO/Future Publishing/Getty People around the world have high levels of trust in scientists, but are concerned about governments interfering in research. These are among the findings reported by the global communications giant Edelman in its…

Hwang Lightning bolts of lime green flashed chaotically across the computer screen, a sight that stunned cancer neuroscientist Humsa Venkatesh. It was late 2017, and she was watching a storm of electrical activity…

Abstract Sensorimotor adaptation is essential for keeping our movements well calibrated in response to changes in the body and environment. For over a century, researchers have studied sensorimotor adaptation in laboratory settings that typically involve small sample sizes. While this approach has proved useful for characterizing different learning processes, laboratory studies are not well suited…

(CBC) The Nature of Things is offering a one-day workshop and networking opportunity for up to 15 selected documentary filmmakers or production crew from the Indigenous, Black, racialized, 2SLGBTQ+, and/or Deaf and Disabled communities based in Manitoba. The goal of this in-person workshop is to introduce participants to key decision-makers and insider information about science…
