Published How does biodiversity change globally? Detecting accurate trends may be currently unfeasible
(via sciencedaily.com) 
Existing data are too biased to provide a reliable picture of the global average of local species richness trends.
Published Can clay capture carbon dioxide?
(via sciencedaily.com) 
Scientists have been using powerful computer models combined with laboratory experiments to study how a kind of clay can soak up carbon dioxide and store it.
Published Packaged DNA: New method to promote bone growth
(via sciencedaily.com) 
DNA can help to stimulate bone healing in a localized and targeted manner, for example after a complicated fracture or after severe tissue loss following surgery. Scientists have developed a new process in which they coat implant materials with a gene-activated biomaterial that induces stem cells to produce bone tissue.
Published Endangered Bahamas bird may be lost from island following hurricane
(via sciencedaily.com) 
The endangered Bahama Warbler may be surviving on just one island following Hurricane Dorian's devastation in 2019, according to researchers. A new study shows the bird's distribution and ecology on Grand Bahama before the hurricane struck. But the team says that the warbler may now only survive on neighboring Abaco island, after hurricane Dorian destroyed the bird's forest habitat on Grand Bahama. The research comes from the same team that found what is thought to have been the last living Bahama Nuthatch, previously thought to have been extinct.
Published Marine reserves unlikely to restore marine ecosystems
(via sciencedaily.com) 
Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact -- mainly fishing --, but, are they enough to recover the functioning of these systems? A study now highlights the limitations of marine reserves in restoring food webs to their pristine state prior to the impact of intensive fishing.
Published 'Game-changing' findings for sustainable hydrogen production
(via sciencedaily.com) 
Hydrogen fuel could be a more viable alternative to traditional fossil fuels, according to University of Surrey researchers who have found that a type of metal-free catalysts could contribute to the development of cost-effective and sustainable hydrogen production technologies.
Published Global wetlands losses overestimated despite high losses in many regions
(via sciencedaily.com) 
New analysis shows the U.S. has accounted for more wetland conversion and degradation than any other country. Its findings help better explain the causes and impacts of such losses and inform protection and restoration of wetlands.
Published A fossil fruit from California shows ancestors of coffee and potatoes survived cataclysm that killed the dinosaurs
(via sciencedaily.com)
Original source 
The discovery of an 80-million-year-old fossil plant pushes back the known origins of lamiids to the Cretaceous, extending the record of nearly 40,000 species of flowering plants including modern-day staple crops like coffee, tomatoes, potatoes and mint.
Published Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time
(via sciencedaily.com) 
New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.
Published Pacific Northwest heat dome tree damage more about temperature than drought, scientists say
(via sciencedaily.com)
Original source 
Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, researchers say.
Published Small isolated wetlands are pollution-catching powerhouses
(via sciencedaily.com)
Original source 
Small isolated wetlands that are full for only part of the year are often the first to be removed for development or agriculture, but a new study shows that they can be twice as effective in protecting downstream lake or river ecosystems than if they were connected to them.
Published Protected areas fail to safeguard more than 75% of global insect species
(via sciencedaily.com) 
Insects play crucial roles in almost every ecosystem -- they pollinate more than 80% of plants and are a major source of food for thousands of vertebrate species -- but insect populations are collapsing around the globe, and they continue to be overlooked by conservation efforts. Protected areas can safeguard threatened species but only if these threatened species actually live within the areas we protect. A new study found that 76% of insect species are not adequately covered by protected areas.
Published Passive radiative cooling can now be controlled electrically
(via sciencedaily.com) 
Energy-efficient ways of cooling buildings and vehicles will be required in a changing climate. Researchers have now shown that electrical tuning of passive radiative cooling can be used to control temperatures of a material at ambient temperatures and air pressure.
Published Smart stitches could reduce infection and simplify post op monitoring
(via sciencedaily.com) 
A new antimicrobial suture material that glows in medical imaging could provide a promising alternative for mesh implants and internal stitches.
Published Transforming the way cancer vaccines are designed and made
(via sciencedaily.com) 
A new way to significantly increase the potency of almost any vaccine has been developed. The scientists used chemistry and nanotechnology to change the structural location of adjuvants and antigens on and within a nanoscale vaccine, greatly increasing vaccine performance in seven different types of cancer. The architecture is critical to vaccine effectiveness, the study shows.
Published This groundbreaking biomaterial heals tissues from the inside out
(via sciencedaily.com) 
A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.
Published Mixing between species reduces vulnerability to climate change
(via sciencedaily.com) 
New research provides rare evidence that natural hybridization can reduce the risk of extinction of species threatened by climate change. Researchers have identified genes that enable Rainbowfish to adapt to climate variations across the Australia using environmental models to work out how much evolution will likely be required for populations to keep pace with future climate change.
Published UK's Overseas Territories at ongoing risk from wide range of invasive species
(via sciencedaily.com) 
A new study has for the first time predicted which invasive species could pose a future threat to the UK's ecologically unique Overseas Territories.
Published A fairy-like robot flies by the power of wind and light
(via sciencedaily.com) 
The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?
Published Researchers demo new type of carbon nanotube yarn that harvests mechanical energy
(via sciencedaily.com) 
Nanotechnology researchers have made novel carbon nanotube yarns that convert mechanical movement into electricity more effectively than other material-based energy harvesters.
