Chemistry Research ‘Rocks’ New Data about Ancient Life

University of California San Diego

Sulfur isotopes can serve as tracers of atmospheric oxygen, and new data collected from the present-day atmosphere in China by an international team of researchers, led by the University of California San Diego, indicate remarkable similarity to the isotopic footprint found in ancient rocks. This opens up new interpretations of the Archean Period’s sulfur isotope sedimentary signature—a proxy for the origins and evolution of atmospheric oxygen and early life on Earth.

Blocking Digestive Hormone May Prevent Diet-Induced Pancreatic Cancer

American Physiological Society (APS)

A high-fat diet may promote the growth of pancreatic cancer independent of obesity because of the interaction between dietary fat and cholecystokinin (CCK), a digestive hormone. In addition, blocking CCK may help prevent the spread of pancreatic tumors to other areas of the body (metastases).

In a First, Scientists Precisely Measure How Synthetic Diamonds Grow

SLAC National Accelerator Laboratory

Scientists have now observed for the first time how diamonds grow from seed at an atomic level, and discovered just how big the seeds need to be to kick the crystal growing process into overdrive.

New Study That Could Improve Diagnosis, Treatment for Transgender Patients Presented at the 70th AACC Annual Scientific Meeting

American Association for Clinical Chemistry (AACC)

Novel findings unveiled at the 70th AACC Annual Scientific Meeting & Clinical Lab Expo show that gender-affirming hormone therapy markedly impacts the results of common laboratory tests for transgender patients. This study underscores the need for transgender-specific reference intervals to ensure this underserved population receives accurate diagnoses and effective treatments.

Soil Phosphorus Availability and Lime: More Than Just pH?

American Society of Agronomy (ASA), Crop Science Society of America (CSSA), Soil Science Society of America (SSSA)

Plants can’t do without phosphorus. But there is often a ‘withdrawal limit’ on how much phosphorus they can get from the soil. A new study looks at how liming, soil management history, and enzymes relate to plants' access to phosphorus.

Breaking Research Reveals That Not All Home Ovulation Tests Are Equally Reliable

American Association for Clinical Chemistry (AACC)

Research announced today at the 70th AACC Annual Scientific Meeting & Clinical Lab Expo reveals that two out of three of the digital home ovulation tests sold by U.S. retailers do not accurately predict when a woman is ovulating. This information is critical for women trying to get pregnant and could improve their chances by helping them to better select at-home tests to guide intercourse timing.
