‘We have only seen this species a handful of times in the 42 years': Whale watchers spot great white sharks off Gloucester
'The sea was in this sort of glass state,' Johnston, 28, of Newburyport, recalled. 'Our captain Jay said, 'This is one of those days we're gonna see a shark.'' The tour group decided to 'go out and explore' instead of heading straight toward a far-off group of whales. That's when Johnston spotted a fin cutting through the water from a half‑mile away. 'The shark came right in front of the boat and we recognized that it was a great white,' Johnston said. 'Then we saw another fin and thought, 'What are the chances it would be a second great white?'' Advertisement Both sharks were identified as juvenile, meaning they were between six and 10-feet long, according to Johnston. 'It's incredibly rare,' Johnston said. 'In the 7,000 trips [Captain Salvatore 'Jay' Frontierro] has done, he has seen great whites six times, and this was his first time seeing two at the same time." The most common sharks whale watchers in the area encounter are basking sharks and blue sharks, according to Johnston. Advertisement 'We have only seen this species a handful of times in the 42 years we have been in business,' 7 Seas Whale Watch said in a The two sharks 'did not seem to interact with each other,' Johnston said, but it is 'not uncommon' for great whites to be looking for food in the same area. 'They were just doing what sharks do, circling, looking for food, giving us some close looks,' Johnston said. Crews and passengers on a 7 Seas Whale Watch cruise spotted two great white sharks swimming in the water 10 miles north of Gloucester on Wednesday, June 25. On the same excursion, crews and passengers also saw a group of three humpback whales — a female named Tripod and two males named Whirlwind and Chromosome — according to Johnston. Johnston said that several recent great white shark sightings off of Massachusetts could be a result of a heat wave, which increased water temperatures, driving the fish further north. On Tuesday, a 10-foot long great white was spotted in Cape Cod off of Eastham, according to The Atlantic White Shark Conservancy White sharks rely on grey seals as a primary food source, Johnston said, and as the once-endangered seal population rebounds, it's also helping the shark population grow — leading to more frequent sightings. 'I wouldn't be shocked if we see another on this year,' Johnston said. Sarah Mesdjian can be reached at

Creative Bioarray Launches Comprehensive In Vitro Test Panels for Genotoxicity Assessment
Creative Bioarray Launches Comprehensive In Vitro Test Panels for Genotoxicity Assessment NEW YORK CITY, NY, UNITED STATES, February 10, 2025 / / -- Creative Bioarray, a pioneer in providing innovative solutions for biological research and testing, proudly announces the launch of its standard array of in vitro test panels tailored for comprehensive genotoxicity assessment. This groundbreaking suite of services includes pivotal tests recognized under the Organization for Economic Co-operation and Development (OECD) guidelines, establishing Creative Bioarray as a key player in the field of toxicological research. Genotoxicity testing is a crucial component in the safety evaluation of chemical compounds, pharmaceuticals, and cosmetics. Understanding a substance's potential to cause genetic damage is vital for ensuring the safety of products throughout their lifecycle. Creative Bioarray's newly developed In Vitro Toxicology Services includes: Bacterial Reverse Mutation Test (OECD TG 471): This test, also known as the Ames test, is widely used to assess the mutagenic potential of chemical compounds. By employing various strains of bacteria, this assay provides rapid and reliable results regarding mutations induced by test substances. In Vitro Mammalian Chromosome Aberration Test (OECD TG 473): This assay evaluates the potential of chemicals to induce chromosome damage in cultured mammalian cells, thereby offering insightful data for risk assessment. In Vitro Mammalian Cell Gene Mutation Tests (OECD TG 476 and TG 490): The Hprt and MLA/tk tests are fundamental in detecting gene mutations in mammalian cells. By providing essential data on the effects of substances at the genetic level, these tests are integral to comprehensive risk assessments. In Vitro Mammalian Cell Micronucleus Test (OECD TG 487): This test identifies the genotoxic potential of chemicals by assessing the formation of micronuclei in cultured cells, providing further evidence of chromosomal damage. In addition to these core assays, Creative Bioarray offers a suite of supplementary genotoxicity assays, including the in vitro comet assay and advanced genotoxicity screening methods. This expansion of services allows researchers to conduct thorough evaluations of substances, assisting in meeting regulatory requirements and enhancing product safety. 'Our goal at Creative Bioarray is to support the scientific community with cutting-edge testing solutions that facilitate safer products for consumers,' said Hannah Cole, the marketing director at Creative Bioarray. 'With our new in vitro test panels, we are committed to providing comprehensive, reliable, and efficient methods for genotoxicity assessment.' The launch of these test panels signifies Creative Bioarray's ongoing dedication to advancing scientific research and improving assessment methods for genotoxicity. Researchers and companies can now rely on Creative Bioarray's expertise to enhance their product development processes while adhering to the highest safety standards. About Creative Bioarray Creative Bioarray is a leading provider of biological research and testing solutions, specializing in in vitro assays, genomics, and proteomics. With a focus on innovation and quality, Creative Bioarray is dedicated to empowering researchers and enhancing product safety globally. Hannah Cole 16313868241 Legal Disclaimer:
