Hurricane Katrina was not dangerous until it hit land in Louisiana. But it intensified and since activists had successfully lobbied the Clinton administration to prevent the Army Corps of Engineers from making repairs, devastation occurred.

Injuries and lives lost may have been reduced if there was a better way to predict when a commonplace tropical depression or tropical storm will intensify. 

A new paper says there’s more than one mechanism that causes rapid intensification. 

The benefits of fluoridated water are well-established but when nature rather than science is in charge it can be harmful. The dose makes the poison and over 200 million people worldwide are estimated to be exposed to high fluoride levels in their drinking water.

A new study finds that long-term consumption of water with fluoride levels far above, 1000 percent more, established drinking water standards may be linked to cognitive impairments in children.

Our five senses are gathering information at all times. One way our brain sorts the abundance of information is by combining information from two or more senses, such as between smells and the smoothness of textures, or pitch, color, and musical dimensions.

It may be why we began to associate higher temperatures with warmer colors, lower sound pitches with less elevated positions, or colors with the flavor of particular foods. A new paper argues that such unconscious 'crossmodal' associations with our sense of smell can even affect our perception of colors.

A new paper has given a name for long-term symptoms that test negative for COVID-19 - "long colds."

Coronavirus is very similar to the common cold, so similar that coronavirus was not known to be distinct until the 1960s. Most who were infected with SARS-CoV-2 and got COVID-19 experienced symptoms like a cold, but those with co-morbidities or who had severe reactions got more like a super flu, some with devastating effect. Even after recovery, some still report lingering effects, given rise to the term 'long COVID.'

Spending on mental health for teens and younger rose by 26 percent from March 2020 to August 2022 - but it may be even higher because the analysis only saw families with employer-provided insurance from one group, Castlight Health, which managers employer-sponsored health insurance plans for about 200 companies. 

Since the introduction of ‘dual treatment’ drugs, survival rates for men with metastatic prostate cancer have increased by an average of six months, according to National Prostate Cancer Register data of all Swedish men diagnosed between 2008 and 2020.

Dual treatment means that patients receive both standard hormone therapy (GnRH therapy) and chemotherapy or androgen receptor blockers. Research has previously shown that men receiving this treatment live approximately one year longer than those receiving GnRH treatment alone.

The results showed that in 2020 40 percent received dual treatment. The average survival rate among these men increased from 2.7 between 2008 and 2012 to 3.2 years in 2017–2020; equivalent to an increase of about six months.
