Changes in Subsistence Hunting Threaten Local Food Security

May 18, 2019 11:40 AM EDT

Scientists with the Universidad San Francisco de Quito and WCS Ecuador Program publishing in the journal Biotropica say that subsistence hunting in Neotropical rain forests - the mainstay of local people as a source of protein and a direct connection to these ecosystems - is in jeopardy from a variety of factors.

Intensive Silviculture Accelerates Atlantic Rainforest Biodiversity Regeneration

May 18, 2019 11:35 AM EDT

An experiment conducted in Brazil in an area of Atlantic Rainforest suggests that intensive silviculture, including the use of herbicide and substantial amounts of fertilizer, is a more effective approach to promoting the regeneration of tropical forest and biomass gain than the traditional method based on manual weeding and less fertilizer.

'Smart' Insulin Could Prevent Hypoglycemia During Diabetes Treatment

May 17, 2019 10:24 AM EDT

UCLA bioengineers and their colleagues have developed a new type of insulin that could help prevent hypoglycemia in people who use the drug to manage diabetes.

Galaxy Blazes with New stars Born From Close Encounter

May 17, 2019 10:19 AM EDT

The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.

Iceland Volcano Eruption in 1783-84 Did Not Spawn Extreme Heat Wave

May 15, 2019 12:00 PM EDT

An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a Rutgers-led study.

The Moon is Quaking as It Shrinks

May 13, 2019 04:56 PM EDT

A 2010 analysis of imagery from NASA's Lunar Reconnaissance Orbiter (LRO) found that the moon shriveled like a raisin as its interior cooled, leaving behind thousands of cliffs called thrust faults on the moon's surface.

Are We Facing A Shortage Of Medical Lab Workers?

May 10, 2019 08:37 PM EDT

Medical laboratory personnel make up a small but essential portion of the number of workers within the health sector. Diagnostics can help to determine whether a patient is well enough to resume working or whether a patient is having an adverse reaction to medicine. Despite this fact, the field isn't a glamorous one, and few new workers are entering to take up the slack from those that are retiring or moving to other professions.
