Ancient Italian fossils reveal risk of parasitic infections due to climate change

Jul 20 2017

In 2014, a team of researchers found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes. Now, an international team has found that rising seas could be detrimental to human health on a much shorter time scale.

Gene variant increases risk for depression, study finds

Jul 20 2017

A gene variant, thought to be carried by nearly 25 percent of the population, increases the odds of developing depression, finds a new study. People with apolipoprotein-E4, called ApoE4 for short, have a 20 percent greater chance of developing clinically significant depressive symptoms later in life compared to those who don't have the gene variant, report the investigators.

Opioids and obesity, not 'despair deaths,' raising mortality rates for white Americans

Jul 20 2017

Drug-related deaths among middle-aged white men increased more than 25-fold between 1980 and 2014, with the bulk of that spike occurring since the mid-1990s when addictive prescription opioids became broadly available, according to new research.

How CRISPR proteins find their target

Jul 20 2017

In addition to the Cas9 protein that bacteria use to bind and snip DNA, bacteria have other Cas proteins that know where to insert that viral DNA into the CRISPR region to remember which viruses have attacked and mount a defense. A research team has discovered how these proteins -- Cas1 and Cas2 -- locate and insert the viral DNA, and it relies on the flexibility of these enzymes and the shape of the DNA.

Biological hydraulic system discovered in tuna fins

Jul 20 2017

The unique system of hydraulic control of fins discovered in tuna indicates a new role for the lymphatic system in vertebrates. This natural mechanism may inspire designs for new 'smart' control surfaces with changeable shape and stiffness for both air and underwater unmanned vehicles.
