Beta blockers are drugs primarily for treating high blood pressure and arrhythmias. They work blocking a hormone known as epinephrine, better known as adrenaline - the same hormone that floods our bodies during times of anxiety and stress.

That’s why beta blockers are becoming popular off-label for anxiety.

Anxiety is not what it used to be. You are not worried about being eaten by a tiger or sacked by Mongol hordes, you are maybe unhappy in your marriage or don't feel appreciated at work. Pills to the rescue, if you are in a wealthy country like America.

So some doctors are recommending them for patients to take in specific instances, rather than general use like antidepressants or benzodiazepines.

Biogenic volatile organic compounds produced by the cannabis plants during growth and reproduction, the same chemicals responsible for the pungent smell of a cannabis plant, also contribute to air pollution on a much larger scale, according to new research.

Cuticular structure in a Late Maastrichtian crab, Costacopluma mexicana, from deposits near the town of from near Paredón, Ramos Arizpe in what is now southern Coahuila (formerly Coahuila de Zaragoza), north-eastern Mexico. We see this same species in the Upper Cretaceous Moyenne of Northeast Morocco and from the Pacific slope, Paleocene of California, USA. This beauty is in the collection of José F. Ventura‎.

Diabetes mellitus and cardiovascular diseases are challenging medical and social problems. Patients with diabetes mellitus are at a higher risk of developing vascular dysfunction and hypertension. Cumulative evidence suggests that oxidative stress may play a key role in the development of diseases.

This fall we will get a new "Teminator" movie, marking 35 years that a dystopian nightmare about robots taking over and killing us all has been front and center in pop culture awareness. 

The dystopian nightmare may happen to fish first. Swimming terminators could be ready to fight against one of the world's most problematic invasive species, the mosquitofish.

When it comes to getting treatment for cancer treatment, your marital status could be making a significant difference in the level of medical care you get, finds a new analysis.

The stakes are high, given that 45 percent (<111 million) U.S. adults are unmarried and given the demographic trend among young people that number is likely to rise.

After Friedrich Wohler accidentally synthesized urea in 1828, chemical synthesis - and organic synthesis for that - has been a driving force in pharmaceutical innovation.

We live longer and better than ever and we can thank the continuous advancement of synthetic chemistry, which allows scientists to design and build new molecules.

A recent analysis of 204,796 news articles about 204 mass shootings(1) over a 40-year period found that President Trump is not inventing things when he mentions a link between shootings and video games. He got it from mainstream media.

The festive lassie you see here is an Anglerfish. They always look to be celebrating a birthday of some kind, albeit solo. This party is happening deep in our oceans right now. The wee candle you see on her forehead is a photophore, a tiny bit of luminous dorsal spine. In anglerfish' world, it's highly alluring. The photophore is an adaptation used to attract prey and mates alike.

Nationalist politics continue to gain support across the European continent, from the UK to Italy, France, Hungary and Poland. Meanwhile, the concept of “Europe” has become a rallying cry for those who want to resist what they see as a constraining, inadequate or conservative vision for the future.
