A recent paper suggests cooking with spices and herbs could close the 1,000 mg gap between the amount of sodium Americans actually consume on a daily basis and the amount recommended by the government Dietary Guidelines for Americans committee.  

In the study, researchers taught adults to flavor their food with spices and herbs instead of salt. At the end of the trial, the intervention group, who had tools including spices and herbs as well as cooking demonstrations, were able to reduce sodium intake by an average of 956.8 mg/day – which is about one-third of the average sodium adults consume each day.

On average, American adults consume 3,300 mg of sodium a day, which is 1,000 mg more than the 2,300 mg/d recommended by the Dietary Guidelines for Americans.

Men with higher exposure to diethylhexyl phthalate (DEHP), one of the phthalates, which is an umbrella term for a group of substances based on phthalic acid, have lower sperm motility and may therefore experience more difficulties conceiving children, according to a new paper.

Many phthalates are found in soft plastics in our daily surroundings: wallpaper, sandals, nail polish, perfume, floors, carpets and more. Some suspect  phthalates may be endocrine disruptors and since phthalate molecules leak out of plastics, we are exposed to it daily and absorb the chemicals through food, drink, skin contact and inhalation. Phthalate levels can be measured by a simple urine sample.  

Researchhas linked the abnormal behavior of two genes (BDNF and DTNBP1) to the underlying cause of schizophrenia. These findings have provided a new target for schizophrenia treatment.

Schizophrenia is a devastating mental disorder that affects nearly 1% of the total human population. The dominant cause of the disorder lies in impaired brain development that eventually leads to imbalanced signals within the brain. This imbalance within the brain is thought to cause hallucinations and paranoia in people with schizophrenia.

In this age of the 24-hour news cycle, instant access to all information everywhere, PubMed, LinkedIn, Facebook, Twitter and hundreds of other ways to glean and share knowledge beyond the traditional stack of printed journals delivered to their door, physicians continue to struggle to arm themselves with the most effective therapies.

Fast access to information may result in practice change; however, subsequent data may disprove effectiveness and require even more practice change. The cycle may continue over several years and several studies, with the potential for missed information growing with each practice-change decision.

Researchers have identified for the first time the triple mechanism that stops chromosome separation in response to situations that compromise the integrity of the genetic information. The loss of this response capacity is characteristic of cancerous cells.

Cell proliferation requires the chromosomes to be copied (replicated) and distributed (segregated) to the two future daughter cells. Cells continually undergo spontaneous alterations (injuries) to the DNA that makes up the chromosomes, because of their aqueous (reactive) environment, for example. In response to DNA injuries, cells put a stop to the cell division cycle, in order to allow time for the injuries to be repaired and prevent the transmission of damaged, incompletely replicated chromosomes.

A new study has found that the Africanized honey bee, an aggressive hybrid of the European honey bee, is continuing to expand its range northward since its introduction into Southern California in 1994. 

The paper in PLOS ONE showed that more than 60 percent of the foraging honey bees in San Diego County are Africanized and that Africanized bees can now be found as far north as California's delta region. 

"Our study shows that the large majority of bees one encounters in San Diego County are Africanized and that most of the bees you encounter are from feral colonies, not managed hives," said Joshua Kohn, a professor of biology at U.C. San Diego, who headed the study.
