| Protecting rare species can benefit human life Posted: 16 May 2019 12:53 PM PDT Preserving rare species for the sake of global biodiversity has long been the primary focus for conservationists. To better protect rare animals, insects and plants, and to prepare for an uncertain future influenced by climate change, a team of researchers is aiming to merge this conventional wisdom with a new way of thinking: arguing researchers needs to better understand how rare species benefit people outside of their existence value. |
| Designing biological movement on the nanometer scale Posted: 16 May 2019 11:29 AM PDT Synthetic proteins have now been created that can move in response to their environment in predictable and tunable ways. These proteins can use their movement to disrupt lipid membranes in cells. They show promise as tools for drug delivery, and might eventually rival the efficiency of virus vehicles, but without some of their drawbacks. |
| How host-cell enzymes combat the coronavirus Posted: 16 May 2019 11:29 AM PDT Host-cell enzymes called PARP12 and PARP14 are important for inhibiting mutant forms of a coronavirus, according to a new study. |
| Natural compound found in broccoli reawakens the function of potent tumor suppressor Posted: 16 May 2019 11:29 AM PDT Long associated with decreased risk of cancer, broccoli and other cruciferous vegetables -- the family of plants that also includes cauliflower, cabbage, collard greens, Brussels sprouts and kale -- contain a molecule that inactivates a gene known to play a role in a variety of common human cancers. A new study demonstrates that targeting the gene, known as WWP1, with the ingredient found in broccoli suppressed tumor growth in cancer-prone lab animals. |
| Scientists find new type of cell that helps tadpoles' tails regenerate Posted: 16 May 2019 11:29 AM PDT Researchers have uncovered a specialized population of skin cells that coordinate tail regeneration in frogs. These 'Regeneration-Organizing Cells' help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues. |
| Could better tests help reverse the rise of drug-resistant infections? Posted: 16 May 2019 11:28 AM PDT Faster, more accurate tests for drug-resistant infections are hailed as a promising tool in the fight against antibiotic resistance, so much so that the US and Britain are offering millions in prize money for their development. A modeling study shows that better tests could, in theory, change the game and put drug-resistant bacteria at a reproductive disadvantage relative to more easily-treated strains -- but with a caveat. |
| Mutation makes bulldogs and Norwich terriers more susceptible to breathing problems Posted: 16 May 2019 11:28 AM PDT The discovery of a new mutation associated with breathing difficulties in popular dog breeds suggests that shortened skulls causing flat faces is not the only factor that contributes to the condition, but that swelling around the airways from edema may also play a role. |
| True identity of imposter 'pigs' on 17th century map overturns early colonial history of Barbados Posted: 16 May 2019 10:17 AM PDT Which came first, the pigs or the pioneers? In Barbados, that has been a historical mystery ever since the first English colonists arrived in 1627 to encounter what they thought was a herd of wild European pigs. Research is shedding new light on the mystery and the altering of New World environments. |
| Posted: 16 May 2019 10:17 AM PDT A native mosquito in Missouri has fewer parasites when it shares its waters with an interloper, according to new research. |
| Measuring plant improvements to help farmers boost production Posted: 16 May 2019 10:17 AM PDT Today, scientists have shown a new technology can more quickly scan an entire field of plants to capture improvements in their natural capacity to harvest energy from the sun. |
| Ritter Island gives new insights into the dynamics of volcanic landslides Posted: 16 May 2019 08:46 AM PDT The flanks of many island volcanoes slide very slowly towards the sea. Whether these landslides are forewarnings of a catastrophic collapse or, on the contrary, even reduce its risk, is not yet understood. Geophysicists now show that sporadic, slow landslides on the small volcanic island of Ritter Island in New Guinea preceded a catastrophic collapse. |
| Algal blooms in Lake Erie's central basin could produce neurotoxins Posted: 16 May 2019 08:46 AM PDT Harmful algal blooms pose a unique toxic threat in Lake Erie's central basin, new research has found. Not only do blooms routinely occur in this area, which previously was not thought to be an area of concern, they can also produce types of cyanobacterial toxins that aren't typically detected through routine water-safety monitoring, according to a new study. |
| Shedding light on the key determinants of global land use projections Posted: 16 May 2019 08:46 AM PDT Land use is at the core of various sustainable development goals. An international research group has endeavored to disentangle the key determinants of global land use projections. |
| Bio-inspired material targets oceans' uranium stores for sustainable nuclear energy Posted: 16 May 2019 08:46 AM PDT Scientists have demonstrated a new bio-inspired material for an eco-friendly and cost-effective approach to recovering uranium from seawater. The low-cost polymer adsorbent could help push past bottlenecks in the cost and efficiency of extracting uranium resources from oceans for sustainable energy production. |
| Fecal microbiota transplant found safe and effective in children with C. difficile Posted: 16 May 2019 08:46 AM PDT Fecal microbiota transplant (FMT), or the transfer of stool from a healthy donor to a patient, has been found effective in reversing severe, recurring diarrheal infections from Clostridiodes difficile in adults by restoring a normal microbiome. Now, the largest study to date of FMT in children finds the procedure to be safe and effective in eradicating an infection that is on the rise among children, even those without known risk factors. |
| Bedbugs evolved more than 100 million years ago Posted: 16 May 2019 08:46 AM PDT Bedbugs -- some of the most unwanted human bed-mates -- have been parasitic companions with other species aside from humans for more than 100 million years, walking the earth at the same time as dinosaurs. |
| Nearly a quarter of West Antarctic ice is now unstable Posted: 16 May 2019 08:46 AM PDT In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that a quarter of its glacier ice is now affected, according to a new study. |
| How plants are working hard for the planet Posted: 16 May 2019 08:45 AM PDT As the planet warms, plants are working to slow the effect of human-caused climate change -- and new research has assessed how plants are responding to increasing carbon dioxide (CO2). |
| Antibody responses vs. Ebola keep evolving in survivors, months after recovery Posted: 16 May 2019 08:45 AM PDT Antiviral antibodies produced by survivors of Ebola infection continue to evolve and improve after recovery, according to a study of immune responses in four people who received care at Emory University Hospital in 2014. High levels of neutralizing antibodies- thought to be key to protecting someone against deadly infection -- didn't appear in patients' blood until months after they left the hospital. |
| Heavily processed foods cause overeating and weight gain, study finds Posted: 16 May 2019 08:45 AM PDT People eating ultra-processed foods ate more calories and gained more weight than when they ate a minimally processed diet, according to results from a new study. The difference occurred even though meals provided to the volunteers in both the ultra-processed and minimally processed diets had the same number of calories and macronutrients. |
| Nutrition: Substantial benefit from replacing steak with fish Posted: 16 May 2019 08:45 AM PDT Consumers will gain a health benefit from substituting part of the red and processed meat in their diet with fish, according to new calculations. Men over 50 and women of childbearing age in particular would benefit from such a change in diet. |
| Human antibody reveals hidden vulnerability in influenza virus Posted: 16 May 2019 08:45 AM PDT The ever-changing 'head' of an influenza virus protein has an unexpected Achilles heel, report scientists. The team discovered the structure of a naturally occurring human antibody that recognizes and disrupts a portion of the hemagglutinin (HA) protein that the virus uses to enter and infect cells. The investigators determined that the antibody, FluA-20, binds tightly to an area on the head of the HA protein that is only briefly accessible to antibody attack. |
| Key step in cell protein production Posted: 16 May 2019 08:45 AM PDT Scientists have discovered how genes create proteins in research which could aid the development of treatments for human diseases. |
| Global invasion routes of the red swamp crayfish, described based on genetics Posted: 16 May 2019 08:45 AM PDT Researchers have identified the main introduction routes of the red swamp crayfish, Procambarus clarkii, during its global-scale invasion. This North American species is the most widely spread freshwater crayfish worldwide and is one of the worst invasive species due to its impact on the structure and functioning of freshwater ecosystems. |
| People recycle more when they know what recyclable waste becomes Posted: 16 May 2019 07:37 AM PDT A new study shows that consumers recycle more when they think about how their waste can be transformed into new products. Change the conversation from 'Where does this go?' to 'What does this create?' to increase recycling rates. |
| Improving carbon-capturing with metal-organic frameworks Posted: 16 May 2019 07:37 AM PDT Chemical engineers have designed an easy method to achieve commercially attractive carbon-capturing with metal-organic frameworks. |
| Organic animal farms benefit birds nesting in agricultural environments Posted: 16 May 2019 07:14 AM PDT Environmental subsidies for agriculture awarded by the European Union aim to improve biodiversity in agricultural environments. A recently completed Finnish study indicates that the proximity of organic animal farms increases bird numbers, and this has enabled environmental subsidies to positively impact bird populations. |
| Posted: 16 May 2019 07:14 AM PDT Evolution and dietary habits interact and determine the composition of bacteria in the digestive tract. Many microorganisms in the intestine seem to have developed in sync with their host animals over millions of years. |
| Research links civic engagement to resilience Posted: 16 May 2019 07:14 AM PDT Flowers, home-cooked meals and time were among the items donated in the aftermath of the Christchurch terror attacks. A new study has found these simple acts of kindness not only benefited victims, but strengthened the well-being and resilience of those giving them. |
| Warming climate threatens microbes in alpine streams Posted: 16 May 2019 06:08 AM PDT Changes to alpine streams fed by glaciers and snowfields due to a warming climate threaten to dramatically alter the types of bacteria and other microbes in those streams, according to new research. But streams that are fed by underground ice insulated by rock -- called 'icy seeps' -- offer some hope that the impact of climate change will be less severe in some areas. |
| Australian islands home to 414 million pieces of plastic pollution Posted: 16 May 2019 06:08 AM PDT A survey of plastic pollution on Australia's Cocos (Keeling) Islands has revealed the territory's beaches are littered with an estimated 414 million pieces of plastic debris. The study estimated beaches on the Indian Ocean islands are littered with 238 tons of plastic, including 977,000 shoes and 373,000 toothbrushes. |
| Antibiotic treatment alleviates Alzheimer's disease symptoms in male mice Posted: 16 May 2019 06:08 AM PDT Researchers have demonstrated that the type of bacteria living in the gut can influence the development of Alzheimer's disease symptoms in mice. The study shows that, by altering the gut microbiome, long-term antibiotic treatment reduces inflammation and slows the growth of amyloid plaques in the brains of male mice, though the same treatment has no effect on female animals. |
| Revision to common view on how retinal cells in mammals process light Posted: 16 May 2019 06:08 AM PDT Scientists say that new experiments with mouse eye tissues strongly suggest that a longstanding 'textbook concept' about the way a mammal's retina processes light needs a rewrite. |
| Breakthrough technique for studying gene expression takes root in plants Posted: 16 May 2019 05:24 AM PDT An open-source RNA analysis platform has been successfully used on plant cells for the first time -- a breakthrough that could herald a new era of fundamental research and bolster efforts to engineer more efficient food and biofuel crops. The technology, called Drop-seq is a method for measuring the RNA present in individual cells, allowing scientists to see what genes are being expressed and how this relates to the specific functions of different cell types. |
