BHU's VRD lab gets NABL accreditation
Prof Gopal Nath, principal investigator, said that the laboratory conducted around 9 lakh tests during the Covid-19 pandemic and carried out around 8,000 tests of dengue, Covid, Japanese encephalitis, and others in the past one-and-a-half years. He credited the contribution of Prof Pradyot Prakash (Co-Principal Investigator), and the entire scientific and technical team, for this accomplishment. The team comprises Dr Sudhir Kumar Singh, Dr Alka Shukla, Dr Manoj Kumar, Dr Mayank Gangwar, Deepak Kumar, Sonam Rastogi, Digvijay Singh, Pankaj Kumar, Ashish R.
Singh, and Ajay Kumar. Prof SN Sankhwar, director, Institute of Medical Sciences, expressed happiness over NABL accreditation. tnn

Maharashtra reports 8 Covid-19 cases, 5 from Mumbai
Maharashtra reported eight COVID-19 cases on Sunday, taking the tally in the state since January 1 this year to 2,577, a health department official said. A teacher of the Gurukul School of Art makes an awareness painting of COVID-19, in Mumbai.(ANI) No death was reported in the last 24 hours, he added. Of the new cases reported during the day, five are from Mumbai, two from Pune and one from Kolhapur. Mumbai's tally now stands at 1012, of which 551 were reported in June and 20 so far in July. Since the start of the year, a total of 2,472 persons have recovered from the infection, the state health department said. The health department said it has conducted 33,157 COVID-19 tests in Maharashtra since January 1. Since January 1, a total of 41 persons have died of COVID-19, including 40 with comorbidities.

Study estimates 13 pc of biomedical abstracts published in 2024 involved use of AI
New Delhi: At least 13 per cent of research abstracts published in 2024 could have taken help from a large language model, as they included more of 'style' words seen to be favoured by these AI systems, suggests an analysis of more than 15 million biomedical papers published from 2010 to 2024. Powered by artificial intelligence, large language models are trained on vast amounts of text and can, therefore, respond to human requests in the natural language. Researchers from the University of Tubingen , Germany, said the AI models have caused a drastic shift in the vocabulary used in academic writing, with speculation about their influence in scientific writing being common. The study, published in the journal Science, revealed the emergence of large language models has sparked an increase in the usage of certain "stylistic words", including 'delves', 'showcasing', 'underscores', 'potential', 'findings' and 'critical'. The authors explained that the shift in words used during 2023-2024 were not "content-related nouns", rather style-affecting verbs and adjectives that large language models prefer. For the analysis, the researchers used a public health approach, common during the COVID-19 pandemic, for estimating excess deaths. The method involves comparing deaths during the pandemic with those before to assess the impact of COVID-19 on death rates. The approach modified for this analysis was termed as an "excess word" framework by researchers. The findings show an "unprecedented impact" of AI models on scientific writing in biomedical research, "surpassing the effect of major world events such as the COVID-19 pandemic". "We study vocabulary changes in more than 15 million biomedical abstracts from 2010 to 2024 indexed by PubMed and show how the appearance of (large language models) led to an abrupt increase in the frequency of certain style words," the authors wrote. PubMed is a search engine providing access to biomedical and life sciences literature published from around the world. "This excess word analysis suggests that at least 13.5 per cent of 2024 abstracts were processed with (large language models)," the team wrote. The figure was found to differ across disciplines, countries and journals, hitting 40 per cent in some cases, they said. In computational fields of biomedical research, about 20 per cent of the abstracts involved the use of large language models, which the researchers said could be due to computer science researchers being more familiar with and willing to adopt the technology. In non-English speaking countries, the AI systems can help authors with editing English texts, which could justify their extensive use, the authors said. However, they added that factors such as publication timelines -- which are shorter in computational fields, thereby enabling an earlier detection of AI use in these journals -- would need to be looked at. Therefore, the study's results may be re-evaluated after a couple of publication cycles in all fields and journals for which the methods used here can help, the team said. PTI

Viral: Netizens are shocked to realise what the G in 5G stands for, and it's not gigabyte
Image credits: Getty Images If you were living life peacefully, assuming you knew what the G in 5G, the internet you use daily is, then you are about to lose your mind for some time. It doesn't help the matter that the 'G' in every different data variation such as 3G, 4G, 5G and 10G has a different meaning with gigabyte being the one for only 10G. Recently a post on X by MTN Uganda asked people to answer "without Googling, what does the "G" in 4G and 5G stand for?" The options for the answers were A) Generation B) Gigabyte C) Google and D) Grid Most of the people in the comments section answered B for Gigabyte, however, the answer was A for Generation. Others went for out-of-the-box answers such as Generator, Greed, Good thief, Gamma rays and more. — mtnug (@mtnug) What does 5G mean? Image credits: X/@mtnug 5G is the fifth generation of wireless technology. It is commonly used for smartphones and is better than the previous generations at connecting multiple devices at once. The evolution of the G system began in 1980 with the invention of the mobile phone which allowed for analogue data to be transmitted via phone calls. In 1991, digital came into the arena with 2G and SMS and MMS capabilities were launched. 5G in particular debuted in South Korea in April 2019 and during the Covid-19 pandemic, US researchers found that the effects of radio-frequency radiation generated by ultra-fast mobile internet had a negligible health impact. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Trending in in 2025: Local network access control [Click Here] Esseps Learn More Undo The study published in PLOS ONE was done after several 5G masts were vandalised during lockdowns following conspiracy theories that they caused COVID-19. Thus, the researchers conducted experiments using embryonic zebrafish, an organism whose 70% genes match those of humans, meaning the results of experiments on them can be confidently applied to humans. They exposed the zebrafishes to 3.5 GHz radio frequency radiation for two days in a box made of copper. The radiation entered the box through an antenna and the copper prevented the radiation from escaping. In the results, experts found no significant impacts on mortality thus meaning that 5G is safer for humans than any other data variation. So the next time you talk about 5G internet you know it's fifth generation and not five gigabytes.
