| Mangrove and reef restoration yield positive returns on investment for flood protection, study shows Posted: 17 Jun 2022 09:23 AM PDT Restoration of mangroves and coral reefs can be a cost-effective solution for coastal flood reduction in more than 20 countries across the Caribbean. Researchers used methods from the risk and insurance industry to provide rigorous valuations of these natural defenses and show that they can deliver a positive return on investment, with the benefits from reduced flood damage exceeding the costs of restoration. The results point toward new opportunities to support restoration efforts with funds from sources that support hazard mitigation, climate adaptation, and disaster recovery, including FEMA. |
| Biogas and biomethane supply chains leak twice as much methane as first thought Posted: 17 Jun 2022 08:14 AM PDT A new analysis has found that biogas and biomethane, while more climate friendly, leak more than twice as much methane as previously thought. |
| More than one way to skin a tumor Posted: 17 Jun 2022 07:18 AM PDT The mechanism by which active inflammation occurs in parallel with immunosuppression in the tumor microenvironment has been identified. Results showed reduced gene expression of regulatory T cell involved in immunosuppression. Cancer treatment employing EP2/EP4 inhibitors might benefit some cancer patients. |
| Next gen television and computer screens: Creating optically active polymers Posted: 17 Jun 2022 07:18 AM PDT A University of Tsukuba researcher describes a new method for obtaining conjugated polymers in a helical configuration. By using twisted liquid crystals as a template, the resulting polymers were found to be able to convert linearly polarized light into circularly polarized light. This work may be used for next-generation television and computer screens. |
| Are new corals in Sydney dangerous invaders or harmless refugees? Posted: 17 Jun 2022 07:18 AM PDT A new study has found that invading subtropical corals will survive and thrive in coastal Sydney, which could spell trouble for existing Sydney coral species. |
| Electrically conductive paints and other polymer alloys now produced easily Posted: 17 Jun 2022 07:18 AM PDT Researchers have synthesized electrically conductive polyaniline polymer in common organic solvents. A small quantity of added iodine facilitates the radical chain reaction that is critical to polymer synthesis. This protocol will facilitate processing of polyaniline in printed circuit boards, electrically conductive paints, and other advanced technologies, in a cheap and versatile manner. |
| New polymer mesophase structure discovered? Posted: 17 Jun 2022 07:18 AM PDT Researchers describe a new polymer structure called a bilayer-folded mesophase that has been discovered through a random copolymer sequence. |
| A new hope for a therapy against retinitis pigmentosa Posted: 17 Jun 2022 07:18 AM PDT Retinitis pigmentosa, a degenerative genetic disease of the eye, is characterized by progressive vision loss, usually leading to blindness. In some patients, structural defects in the photoreceptor cells have been observed, but the molecular mechanisms involved are not understood. A team has identified the essential role played by a molecular zipper formed by four proteins. The absence of this zipper leads to cell death in retinal cells. This discovery could lead to the development of therapeutic approaches for retinitis pigmentosa. |
| Training virtually can reduce psychosocial stress and anxiety Posted: 17 Jun 2022 07:18 AM PDT Everyone knows that exercise brings physical and psychological benefits. A new study suggests that virtual reality exercise induces similar effects, meaning those with limited mobility may be able to improve their mental well-being. |
| Forest to pasture: Keeping trees could reduce climate consequences Posted: 17 Jun 2022 07:18 AM PDT Researchers studied a practice known as silvopasture which intentionally preserves trees in pastures where livestock graze. They found that compared to a completely cleared, tree-less, open pasture, the integrated silvopasture released lower levels of carbon dioxide and nitrous oxide and soil carbon storage remained the same, offering a possible alternative for farmers with less climate consequences. |
| Engineers create single-step, all-in-one 3D printing method to make robotic materials Posted: 16 Jun 2022 11:27 AM PDT Engineers have developed a new design strategy and 3D printing technique to build robots in one single step. The breakthrough enabled the entire mechanical and electronic systems needed to operate a robot to be manufactured all at once by a new type of 3D printing process for engineered active materials with multiple functions (also known as metamaterials). Once 3D printed, a 'meta-bot' will be capable of propulsion, movement, sensing and decision-making. |
| Scientists unravel the mystery of genes that are key to brain development Posted: 16 Jun 2022 11:27 AM PDT New research shows the mechanism by which genes coding for a subset of long non-coding RNA (lncRNA) interact with neighboring genes to regulate the development and function of essential nerve cells. |
| Gold ribbon not necessary: Healthy brain and body function are the rewards in this game Posted: 16 Jun 2022 07:19 AM PDT Researchers have found that even the oldest adults can benefit from a game-like intervention that targets cognitive and physical function by combining body movement with tasks that stimulate frontal, temporal, and occipital brain activity to prevent age-associated declines. |
