Exoskeletons shape the future of industrial and logistic jobs

Making workplaces healthier, safer, more productive, and more attractive – that is how Ottobock Bionic Exoskeletons shapes the future of work. The company, a leading manufacturer of exoskeletons, will present its product portfolio at the ProMat 2023 trade show in Chicago from March 20th – 23rd at booth N6354. Exoskeletons augment the human body and reduce strain during manual load-handling tasks, which reduces work-related injuries while increasing well-being and productivity.

‘Like dancing with a really bad partner’: Exoskeletons can confuse the brain, researchers say

Columbus, OH — The physical benefits that exoskeletons provide to the musculoskeletal system may be negated by the “mental strain” that results when workers wearing the devices perform tasks that require them to think about their actions, results of a recent study conducted by researchers from Ohio State and Texas A&M universities indicate.

Yukos skeletons. What links Aleksey Golubovich with former owners of the oil company. Part I

Russia's refusal to pay $50 billion to former Yukos shareholders will lead to new investigations.On March 31, the Moscow City Court will consider an appeal, which was filed against the ruling to pay $35 million to former Yukos shareholder Alexey Golubovich by his ex-wife Olga Mirimskaya. Allegedly, she received the money for the sale of Yukos shares 15 years ago, and her ex-husband asked for his share as part of the divorce proceedings that have been ongoing for the last ten years. These are unusual demands as Mirimskaya has never owned shares in the oil company. In addition, Golubovich was not only its shareholder, but also served as the director for strategic planning and corporate finance at OAO NK Yukos and was aware of all information related to the financial dealings of the oil giant. A journalistic investigation conducted by Pravda.Ru showed that Alexey Golubovich likely still works in close collaboration with other ex-owners of Yukos. Alexey Golubovich, a former shareholder of Yukos oil company, and Olga Mirimskaya, the chairwoman of the Board of Directors of BKF Bank, divorced in 2012, but the litigation over the division of their marital property continues to this day. Olga Mirimskaya is the founder of the Russian Product Company. She is also President of BKF Bank. Mirimskaya is charged with giving a bribe — two vehicles worth a total of 3.25 million rubles — to Yury Nosov, an investigator at the Moscow Region Department of the Investigative Committee in 2017. He handled the case, in which she appeared as a victim in connection with the kidnapping of her daughter. Nosov and Mirimskaya were arrested in the bribery case. They plead not guilty, claiming that the case has been initiated under false pretences with malicious intent. "According to the defendant, the case was initiated by Alexey Golubovich, as well as by her former common-law partner Nikolai Smirnov, a co-owner of the Golden Crown payment system, as an act of revenge for the return of her daughter, in order to seize her property," Mirimskaya's lawyer Alexander Chernov said.

Skeletons of Yukos. Why GML paid Alexey Golubovich $44 million. Part 2

Continued. Read Part I of the article here. Alexey Golubovich, Yukos's former director for strategic planning and corporate finance was one of the main witnesses in the case against Yukos. How can one determine the basis of his testimony? Was it a wish to help the Russian justice system or the subtle game of a "double agent"? In order to understand this, one may need to recall a few facts from his business biography. In the first part of our investigation, we talked about Alexey Golubovich's business projects and lawsuits in 2010–2022, in which one could see both the shadows of his former Yukos colleagues (for example, Mikhail Khodorkovsky, Yuri Beilin) ​and the non-systemic opposition.

African skeletons from early colonial Mexico tell the story of first-generation slaves

(Max Planck Institute for the Science of Human History) Three 16th-century skeletons from a mass burial in Mexico City highlight the role of the transatlantic slave trade in introducing and disseminating new pathogens to the Americas. Researchers from the Max Planck Institute for the Science of Human History and Escuela Nacional de Antropología e Historia in Mexico analyzed skeletal features, genetic data and isotopes to explore the life history of three enslaved Africans and explore the wide-ranging impacts of massive forced migration.
