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.

We get many sensational news stories, saying a giant asteroid will hit Earth, or will nearly miss us. Several so far this year. Many of us worry about these things. So what is the truth behind them?

Actually astronomers have this well in hand for the largest asteroids. They have found 90% of the largest asteroids likely to hit Earth. This is mainly due to Pan-STARRS, which takes a 1.4 gigapixel image of a three degrees span of the night sky several times a minute. It continues to find a new large asteroid about once a month, and will find most of the remaining 10% by the 2020s.

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.

The latest report card on Great Barrier Reef water quality shows signs of improvement, but the health of the marine environment close to the shore remains poor, driven by pollution runoff from the land.

Among the good news is that pollution levels in reef waters have declined in the past five years, and most pollutants seem to track towards the pollution reduction targets set for 2018.

It’s been 60 years since the first TV ad was broadcast in the UK. In that time, we’ve moved from the innocent grainy black-and-white “Tingle of Health” of Gibbs SR toothpaste, to the sophisticated hyper-reality of 4K TV and beyond, in lock-step with developing communications technologies.

The next 60 years will certainly see an even faster pace of change. So what can we look forward to (or not) in the realm of advertising?

Volkswagen has set aside €6.5 billion to cover the costs of the growing scandal over cheating on emissions tests in the US. Putting a number on the cost further down line will be far harder, however, as it is a crisis which calls into question the ethical credentials of the company and the industry, as well as posing tough questions about the regulators and authorities who were duped.

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.
