Higher than normal body mass index (BMI) is known to lead to cardiovascular ill-health in mid-to-late life, but there has been limited investigation of its effect in young, apparently healthy, adults. Researchers have now shown that having a higher BMI can cause worse cardiovascular health in those aged as young as 17.
Scientists using a high-resolution global climate model and historical observations of species distributions on the Northeast US Shelf have found that commercially important species will continue to shift their distribution as ocean waters warm two to three times faster than the global average through the end of this century. Projected increases in surface to bottom waters of 6.6 to 9 degrees F (3.7 to 5.0 degrees C) from current conditions are expected.
MIT engineers have uncovered the secret to the exceptional toughness of conch shells, and say the same principles can be used for body armor and helmets.
A new study by WCS (Wildlife Conservation Society) has revealed how mining for valuable minerals in eastern Democratic Republic of Congo (DRC) is a major driving factor in the illegal hunting of great apes and other wildlife for food.
Melanoma is a particularly difficult cancer to treat once it has metastasized, spreading throughout the body. University of Illinois researchers are using chemistry to find the deadly, elusive malignant cells within a melanoma tumor that hold the potential to spread. Once found, the stemlike metastatic cells can be cultured and screened for their response to a variety of anti-cancer drugs, providing the patient with an individualized treatment plan based on their own cells.
A team of scientists led by the University of Bristol has provided new insights into the origins of the Archaea, the group of simple cellular organisms that are the ancestors of all complex life.
Almost 150 years after Charles Darwin first proposed a little-known prediction from his theory of sexual selection, researchers have found that male moths with larger antennae are better at detecting female signals.
New research from the University of Cincinnati reveals that residents of the mid-Ohio River Valley had higher than normal levels of perfluorooctanoic acid (PFOA) based on serum samples collected over a 22-year span. The exposure source was likely from drinking water contaminated by industrial discharges upriver. This is the first study of PFOA serum concentrations in US residents in the 1990s.
A study of dog DNA has revealed a genetic mutation linked to flat face shapes such as those seen in pugs and bulldogs.
Newly discovered notes show for the first time the Venetian doctor who invented the thermometer and helped lay the foundations for modern medical treatment also played a key role in shaping our understanding of chemistry.
