Although moderately mobile, marine cone snails have perfected several strategies to capture prey. Some fish-hunting species release venom into the surrounding water. Within the plume of toxic venom, the fish succumbs to fast-acting insulin that renders it immobile. As the fish flounders, the snail emerges from its shell to swallow the pacified victim whole.

According to the Centers for Disease Control and Prevention (CDC), gestational diabetes affects an estimated 2 - 10% of pregnancies in the United States. If left untreated, gestational diabetes (GDM) can lead to pregnancy complications, including preterm birth, caesarean delivery and more.

Love can make us do crazy things. It often prompts us to behave in counterintuitive ways, like, for example, placing the wellbeing of our loved ones above our own.

But why?

BOSTON - (February 11, 2019) - It's well-known that exercise improves health, but understanding how it makes you healthier on a molecular level is the question researchers at Joslin Diabetes Center are answering.

After performing experiments in both humans and mice, the researchers found that exercise training causes dramatic changes to fat. Additionally, they discovered that this "trained" fat releases factors into the bloodstream that can have positive effects on health. The study was published online February 11, 2019, in Nature Metabolism.

Many men with low-risk prostate cancer who most likely previously would have undergone immediate surgery or radiation are now adopting a more conservative "active surveillance" strategy, according to an analysis of a new federal database by scientists from Dana-Farber Cancer Institute.

Every county in the United States tracks HIV cases, sequencing the virus' genome to see if it is resistant to current medications and looking for trends. More recently, local health departments and the Centers for Disease Control and Prevention (CDC) have begun using those HIV genetic sequences to trace the virus' transmission history.

Light pollution affects the skies over most of the world's key wildlife areas, new research shows.

The study, by the University of Exeter and Birdlife International, focussed on "skyglow" - light scattered and reflected into the atmosphere that can extend to great distances.

Researchers found less than a third of the world's Key Biodiversity Areas (KBAs) have completely pristine night skies, and more than half lie entirely under artificially bright skies.

Night-time light has been shown to have wide-ranging effects on individual species and entire ecosystems.

Adding olefin enables efficient solvent-free cross-coupling reactions, leading to environmentally friendly syntheses of a wide range of organic materials.

Philadelphia, February 11, 2019 - As marijuana legalization sweeps North America, use of the substance has been on the rise, and the public's attitude is shifting. An increasing number of people believe that "weed" is the safest recreational drug, one that carries health benefits that outweigh its risks.

At least 230 new emoji, when different skin tones and genders are included, are due to be released this year. That’s a leap on 2018 when only 157 emoji were added to the Unicode Standard – the code used to support emoji on different platforms.

Most plants have developed mechanisms to prevent self-fertilization and its detrimental effects of inbreeding depression. Traits promoting selfing in plants have been approached mainly from the perspective of a loss of function, or even only considered as a by-product of non-adaptive evolutionary processes. However, the shift from cross-fertilization to selfing has been identified as one of the most frequent evolutionary transitions. Therefore, adaptive mechanisms actively promoting selfing should be usual in the plant kingdom, but, remarkably, they have not been frequently found.

Under climate change, plants and animals will shift their habitats to track the conditions they are adapted for. As they do, the lands surrounding rivers and streams offer natural migration routes that will take on a new importance as temperatures rise.

An open-access study led by the University of Washington pinpoints which riverside routes in Washington, Oregon, Idaho and western Montana will be the most important for animals trying to navigate a changing climate. The study was published this fall in PLOS ONE.

Acrylics are an incredibly diverse and useful family of chemicals used in all kinds of products, from diapers to nail polish. Now, a team of researchers from UConn and ExxonMobil describe a new process for making them. The new method would increase energy efficiency and reduce toxic byproducts, they report in the Feb. 8 issue of Nature Communications.
