New Report Outlines Research Agenda to Better Understand the Relationship Among Microbiomes, Indoor Environments, and Human Health

Even with a growing body of research on microorganisms and humans in indoor environments, many of their interconnections remain unknown, says a new report by the National Academies of Sciences, Engineering, and Medicine. The report proposes a research agenda to gain a more comprehensive understanding of the formation, dynamics, and functions of indoor microbiomes that can guide improvements to current and future buildings as well as enhance human health and well-being.

New Tool Aims to Make Surgery Safer by Helping Doctors See Nerves

During operations, it can be difficult for surgeons to avoid severing crucial nerves because they look so much like other tissue. A new noninvasive approach that uses polarized light to make nerves stand out from other tissue could help surgeons avoid accidentally injuring nerves or assist them in identifying nerves in need of repair.

Antifreeze to improve aeroplanes, ice cream and organ transplants

The design of airplane wings and storing organs for transplant could both become safer and more effective, thanks to a synthetic antifreeze which prevents the growth of ice crystals, developed by researchers at the University of Warwick.

Turning pollen into a low-cost fertilizer

As the world population continues to balloon, agricultural experts puzzle over how farms will produce enough food to keep up with demand. One tactic involves boosting crop yields. Toward that end, scientists have developed a method to make a low-cost, biocompatible fertilizer with carbon dots derived from rapeseed pollen. The study, appearing in ACS Omega, found that applying the carbon dots to hydroponically cultivated lettuce promoted its growth by 50 percent.

New process allows live look inside insects

Until now, live insects have been too wriggly to make good subjects for scientists wanting to understand more about insect innards. But an interdisciplinary team of biologists and imaging specialists from Western has worked out a novel micro-imaging solution that’s leading to unprecedented new ways of viewing insect development.

Rare Opportunity to Study the Critically Endangered North Pacific right whale in the Bering Sea

Even after so many years of doing field work, sometimes you are still left amazed. Because every now and then the stars all align, and everything works out exactly as you hoped it would. Today was one of those times, because we found that needle in the haystack.

Frogs That Adapt to Pesticides Are More Vulnerable to Parasites

Amphibians can evolve increased tolerance to pesticides, but the adaptation can make them more susceptible to parasites, according to a team that includes researchers at Rensselaer Polytechnic Institute. The research, led by Binghamton University, showed that wood frogs that evolved increased tolerance to pesticides showed greater susceptibility to a dangerous virus, although they also demonstrated reduced susceptibility to a parasitic worm.

“We have only recently begun to understand that amphibians can rapidly evolve tolerance to chemicals like pesticides, which on the surface is good news,” said Rick Relyea, a professor of biological sciences and director of the Darrin Fresh Water Institute at Rensselaer. “But now comes the bad news: with that tolerance there is a tradeoff, which is that they become more susceptible to parasites that, in the case of ranavirus, can wipe out entire amphibian populations.”

Balloons and drones and clouds; oh, my!

Last week, researchers at Sandia National Laboratories flew a tethered balloon and an unmanned aerial system, colloquially known as a drone, together for the first time to get Arctic atmospheric temperatures with better location control than ever before. In addition to providing more precise data for weather and climate models, being able to effectively operate UASs in the Arctic is important for national security.

“Operating UASs in the remote, harsh environments of the Arctic will provide opportunities to harden the technologies in ways that are directly transferable to the needs of national security in terms of robustness and reliability,” said Jon Salton, a Sandia robotics manager. “Ultimately, integrating the specialized operational and sensing needs required for Arctic research will transfer to a variety of national security needs.”
