Mutant corn gene boosts sugar in seeds, leaves, may lead to breeding better crop Posted: 03 May 2021 02:28 PM PDT An abnormal build up of carbohydrates -- sugars and starches -- in the kernels and leaves of a mutant line of corn can be traced to one misregulated gene, and that discovery offers clues about how the plant deals with stress. |
Revealing the secret cocoa pollinators Posted: 03 May 2021 02:28 PM PDT The importance of pollinators to ensure successful harvests and thus global food security is widely acknowledged. However, the specific pollinators for even major crops - such as cocoa - haven't yet been identified. Now an international research team has found that in fact ants and flies - but not ceratopogonid midges - appear to have a crucial role to play. |
Intranasal influenza vaccine enhances immune response and offers broad protection Posted: 03 May 2021 12:13 PM PDT An influenza vaccine that is made of nanoparticles and administered through the nose enhances the body's immune response to influenza virus infection and offers broad protection against different viral strains, according to new research. |
Mating with relatives? Not a big deal in nature Posted: 03 May 2021 11:47 AM PDT The idea that animals should avoid mating with relatives has been the starting point for hundreds of scientific studies performed among many species. But new research shows that there is little support for this assumption. The study provides a synthesis of 139 experimental studies in 88 species and 40 years of research, settling the debate about if and when animals should avoid inbreeding. |
Cell atlas of stony corals is boost for coral reef conservation efforts Posted: 03 May 2021 11:47 AM PDT Single-cell RNA sequencing reveals 40 different cell types in Stylophora pistillata, a reef-building stony coral native to the Indo-Pacific oceans. The calcium carbonate skeleton of stony coral colonies are the main habitat for a huge diversity of marine species. The study has detected the presence of specialized immune cells in corals or any cnidaria. The findings will aid present and future conservation efforts to protect coral reef ecosystems threatened by rising temperatures and ocean acidification. |
Human organ chips enable COVID-19 drug repurposing Posted: 03 May 2021 11:47 AM PDT Emulating the human lung airway in vitro identified the SARS-CoV2-inhibiting effects of the antimalarial drug amodiaquine, which is now in COVID-19 clinical trials. |
Unraveling a mystery of dinoflagellate genomic architecture Posted: 03 May 2021 11:47 AM PDT New work unravels a longstanding mystery about the relationship between form and function in the genetic material of a diverse group of algae called dinoflagellates. The findings have implications for understanding genomic organizational principles of all organisms. |
GM grass cleanses soil of toxic pollutants left by military explosives, new study shows Posted: 03 May 2021 11:45 AM PDT A grass commonly used to fight soil erosion has been genetically modified to successfully remove toxic chemicals left in the ground from munitions that are dangerous to human health, new research shows. |
New research shows long-term recovery possible for areas impacted by seagrass die-off Posted: 03 May 2021 10:56 AM PDT A new study finds nearly 10,000 acres of lush seagrass vanished from Florida Bay over 20 years, leading to massive ecological changes in the region near the Florida Keys. |
Equipping crop plants for climate change Posted: 03 May 2021 10:56 AM PDT Biologists have significantly enhanced the tolerance of blue-green algae to high light levels -- with the aid of artificial evolution in the laboratory. |
Flatfish got weird fast due to evolutionary cascade Posted: 03 May 2021 10:56 AM PDT Flatfishes rapidly evolved into the most asymmetric vertebrates by changing multiple traits at once, according to a new study. |
Bornean rajah scops owl rediscovered after 125 years Posted: 03 May 2021 10:56 AM PDT The Bornean subspecies of Rajah scops owl (Otus brookii brookii), documented in the wild for the first time since 1892, may be its own unique species and deserving of a conservation designation. Researchers reported the rediscovery and photographed this elusive subspecies in the mountainous forests of Mount Kinabalu in Sabah, Malaysia. |
Newly identified giant saber-toothed cat roamed North America 5-9 million years ago Posted: 03 May 2021 08:39 AM PDT A giant saber-toothed cat lived in North America between 5 million and 9 million years ago, weighing up to 900 pounds and hunting prey that likely weighed 1,000 to 2,000 pounds, scientists reported today in a new study. |
Will your future clothes be made of algae? Posted: 03 May 2021 07:48 AM PDT For the first time, researchers have used 3D printers and a novel bioprinting technique to print algae into living, photosynthetic materials that are tough and resilient. |
An animal able to regenerate all of its organs even when it is dissected into three parts Posted: 03 May 2021 07:48 AM PDT This animal, a member of the chordates, can regenerate all of its organs so that each piece knows exactly how to regain functioning of all its missing body systems within a short period of time. |
Less precipitation means less plant diversity Posted: 03 May 2021 07:48 AM PDT Water is a scarce resource in many of the Earth's ecosystems. This scarcity is likely to increase in the course of climate change. This, in turn, might lead to a considerable decline in plant diversity. Using experimental data from all over the world, a team of scientists have demonstrated for the first time that plant biodiversity in drylands is particularly sensitive to changes in precipitation. |
Dogs' aggressive behavior towards humans is often caused by fear Posted: 03 May 2021 07:48 AM PDT A study encompassing some 9,000 dogs demonstrated that fearfulness, age, breed, the company of other members of the same species and the owner's previous experience of dogs were associated with aggressive behavior towards humans. The findings can potentially provide tools for understanding and preventing aggressive behavior. |
Tailor-made therapy of multi-resistant tuberculosis Posted: 03 May 2021 07:00 AM PDT The successful treatment of multidrug-resistant tuberculosis requires clarification in advance as to which antibiotics the pathogens are resistant to. Classic testing is very time-consuming and delays the start of therapy. Researchers have now prepared a catalogue of all mutations in the genome of tuberculosis bacteria and on the basis of a genome sequencing can quickly and cheaply predict which medicines are most effective for tuberculosis treatment. |
How plants find their symbiotic partners Posted: 03 May 2021 07:00 AM PDT Researchers explain an evolutionary step in the symbiosis between plants and nitrogen-fixing bacteria. |
Limited fishing zones support reef conservation Posted: 03 May 2021 06:35 AM PDT Green (no-take) and yellow (limited take) fishing zones within the Great Barrier Reef Marine Park equally support a great diversity of fish species.

Natural immunity to malaria provides clues to potential therapies Posted: 03 May 2021 06:35 AM PDT Researchers have identified how natural human antibodies can block malaria parasites from entering red blood cells, potentially indicating how new protective therapies could be developed against this globally significant disease. The research provides greater insight into how antibodies block the entry of Plasmodium vivax malaria parasites into young red blood cells called reticulocytes. It builds on an earlier discovery that the P. vivax latches onto the transferrin receptor 1 (TfR1) to enter cells. |
Reduction in wetland areas will affect Afrotropical migratory waterbirds Posted: 03 May 2021 06:35 AM PDT Migratory waterbirds are particularly exposed to the effects of climate change at their breeding areas in the High Arctic and in Africa, according to a new study. The research team came to this conclusion after modelling climatic and hydrological conditions under current and future climate scenarios (in 2050) and comparing the impact on the distribution of 197 of the 255 waterbird species listed under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA). |
