Just before it sank, the RMS Titanic ship was sent an iceberg warning by other ships but the message never reached the bridge on the fateful night of 15th April 1912.  Ironic, one merchant steamship SS Mesaba which had sent the message also met with similar fate six years later. In 1912 the merchant steamship SS Mesaba was crossing the Atlantic and sent ...

Stressful life circumstances can affect how married couples interact, but can they affect how partners see each other? A person experiencing stress is more likely to notice their spouse’s negative behavior than positive, according to a new study published in Social Psychological and Personality Science. Prior research has focused on how stress influences behavior, but this study suggests that stress could affect ...

Scientists estimate that more than 95 percent of Earth’s oceans have never been observed, which means we have seen less of our planet’s ocean than we have the far side of the moon or the surface of Mars. The high cost of powering an underwater camera for a long time, by tethering it to a research vessel or sending a ...

An unexpected ‘heat wave’ of 700 degrees Celsius, extending 130,000 kilometres (10 Earth diameters) in Jupiter’s atmosphere, has been discovered. James O’Donoghue, of the Japanese Aerospace Exploration Agency (JAXA), has presented the results this week at the Europlanet Science Congress (EPSC) 2022 in Granada. Jupiter’s atmosphere, famous for its characteristic multicoloured vortices, is also unexpectedly hot: in fact, it is ...

Wearable sensors styled into t-shirts and face masks Imperial researchers have embedded new low-cost sensors that monitor breathing, heart rate, and ammonia into t-shirts and face masks. Potential applications range from monitoring exercise, sleep, and stress to diagnosing and monitoring disease through breath and vital signs. Spun from a new Imperial-developed cotton-based conductive thread called PECOTEX, the sensors cost little ...

A study led by Durham University’s Fetal and Neonatal Research Lab, UK, took 4D ultrasound scans of 100 pregnant women to see how their unborn babies responded after being exposed to flavours from foods eaten by their mothers. Researchers looked at how the fetuses reacted to either carrot or kale flavours just a short time after the flavours had been ...

Activated carbon is used in kitchen fans to eliminate food odours. A new dissertation from the University of Gothenburg shows that activated carbon could also eliminate the smell of urine from diapers. Experiments with the odour molecule p-cresol show that activated carbon, which largely consists of the carbon variant graphene, can lock in odour instead of it being released to ...

Mosquitoes that spread Zika, dengue and yellow fever are guided toward their victims by a scent from human skin. The exact composition of that scent has not been identified until now. A UC Riverside-led team discovered that the combination of carbon dioxide plus two chemicals, 2-ketoglutaric and lactic acids, elicits a scent that causes a mosquito to locate and land ...

NASA Television will provide live coverage of the upcoming Artemis I cryogenic demonstration test on NASA TV beginning at 7:15 a.m. EDT or 4.30 pm IST on Wednesday, Sept. 21. The demonstration test will allow teams to confirm the repair to a hydrogen leak seen during an early September Artemis I launch attempt, evaluate updated propellant loading procedures, and conduct additional evaluations. The demonstration will ...

One approach to treating cancer is photodynamic therapy using photo-uncaging systems, in which light is used to activate a cancer-fighting agent in situ at the tumor. However, suitable agents must be stable under visible light, have an anti-tumor effect in low-oxygen environments, and have the ability to be activated by low-energy tissue-penetrative red light – a combination of properties that is difficult to ...

InSight, which has hit headlines this week with the realtime recording of sound from the Mars when meteoroids struck Mars’ surface at four places since its landing on the Red Planet in November 2018, is nearing the end of its mission by mid-2023. The first NASA mission to explore Mars’ deep interior, InSight rover landed on Mars surface on Nov. ...

The Mars lander’s seismometer has picked up vibrations from four separate impacts in the past two years, which is the first of its kind to have recorded seismic and acoustic waves from an impact on the Red Planet. NASA’s InSight lander has detected seismic waves from four space rocks that crashed on Mars in 2020 and 2021, detected by the ...

Scientists have created a ‘digital mask’ that will allow facial images to be stored in medical records while preventing potentially sensitive personal biometric information from being extracted and shared. In research published today in Nature Medicine, a team led by scientists from the University of Cambridge and Sun Yat-sen University in Guangzhou, China, used three-dimensional (3D) reconstruction and deep learning algorithms ...

Instead of sitting in a tattoo chair for hours enduring painful punctures, imagine getting tattooed by a skin patch containing microscopic needles. Researchers at the Georgia Institute of Technology have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics. “We’ve miniaturized the needle so that it’s ...
