Cannabinoid vaping products, genomic biomarkers to determine tumorigenic potential, and analyses of various testing assays are just a few of the article topics in the July 2022 issue of Toxicological Sciences.
An international team of scientists has developed an accurate record of preindustrial sea level utilizing precisely dated phreatic overgrowths on speleothems that provide a detailed history of Late Holocene sea-level change in Mallorca, Spain, an island in the western Mediterranean Sea. The results provide an unprecedented picture of sea level over the past 4,000 years, putting the preindustrial and modern global mean sea level (GMSL) histories in context.
A new universal flu vaccine constructed with key parts of the influenza virus offers broad cross protection against different strains and subtypes of influenza A viruses in young and aged populations, according to a new study by researchers in the Institute for Biomedical Sciences at Georgia State University.

Noninvasive (stage Ta) bladder cancers with "high-grade" characteristics should be considered at high risk of recurrence, concludes a study in The Journal of Urology®, an Official Journal of the American Urological Association (AUA). The journal is published in the Lippincott portfolio by Wolters Kluwer.
As they get started in their careers, orthopaedic surgeons with subspecialty training in sports medicine spend much of their time performing other types of orthopaedic procedures, reports a study in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.
The experts agree — the pandemic is not over. Infections are ticking up again, fueled by the new variants our immune systems are ill prepared for.
Despite significant and stunning advances in vaccine technology, the COVID-19 global pandemic is not over.
What do peanut aflatoxins, aquaponics, integrated pest management for crops and sealed timber bids have in common? They are all subjects of practical application in Land-Grant Press by Clemson Extension publications. Written by Cooperative Extension agents and University scientists, Land-Grant Press publications are research-based, peer-reviewed scholarly work.
S&P Global Ratings assigned its ‘A’ issuer credit rating with a stable outlook to Ochsner Clinic Foundation d/b/a Ochsner Health (Ochsner). S&P Global Ratings issued a report on Wednesday, June 29 that reflected confidence in Ochsner’s finances, growth and leadership.

They may only be in 4th or 5th grade, but 1 in 10 pre-teen children already say they’re curious about using alcohol or tobacco products, and 1 in 50 say they’re curious about using marijuana, a new study shows. As many as 3% of the nearly 12,000 9- and 10-year-olds surveyed say they already have a friend who uses one of these substances. And those who said they did were also much more likely to be curious about trying alcohol or tobacco and other nicotine-containing products themselves.
