These results demonstrate that parasites can manipulate the host's specific light perception system to their advantage, causing the host to behave in an abnormal manner. |
| Success in reversing dementia in mice sets the stage for human clinical trials Posted: 29 Jun 2021 09:07 AM PDT Researchers have identified a new treatment candidate that appears to not only halt neurodegenerative symptoms in mouse models of dementia and Alzheimer's disease, but also reverse the effects of the disorders. |

| Posted: 29 Jun 2021 09:07 AM PDT Earthworms are special because they keep our soil healthy. From the outside they appear inconspicuous. But what earthworms look like from the inside, from their organs to the microbes and parasites that colonize them, has been difficult to grasp. Scientists have developed a method to visualize anatomical structures including products of an earthworm's metabolism. |

| COVID-19's socio-economic fallout threatens global coffee industry, study finds Posted: 29 Jun 2021 07:12 AM PDT COVID-19's socio-economic effects will likely cause another severe production crisis in the coffee industry, according to a new study. |
| How humans brought change to a tropical paradise Posted: 29 Jun 2021 07:12 AM PDT After centuries of human impact on the world's ecosystems, a new study details an example of how a common native bee species has flourished since the very first land clearances by humans on Fiji. |
| Mongoose in the city: How landscape can impact disease transmission in Botswana Posted: 29 Jun 2021 07:12 AM PDT Under a concrete drainage culvert at the edge of a town in Botswana, a troop of banded mongoose is getting ready to leave its den. Moving from shade into light, the cat-sized animals scan the area for signs of danger and for opportunities to find something to eat in an increasingly crowded neighborhood. |
| Air pollution from wildfires impacts ability to observe birds Posted: 29 Jun 2021 07:12 AM PDT Researchers provide a first look at the probability of observing common birds as air pollution worsens during wildfire seasons. They found that smoke affected the ability to detect more than a third of the bird species studied in Washington state over a four-year period. Sometimes smoke made it harder to observe birds, while other species were actually easier to detect when smoke was present. |
| Better way to study reputedly secretive toad Posted: 29 Jun 2021 07:12 AM PDT New research has upended the conventional wisdom that for a century has incorrectly guided the study of a toad listed as endangered in part of its range. |

| New insight into photosynthesis could help grow more resilient plants Posted: 28 Jun 2021 03:07 PM PDT A research team has created a computer model to understand how plants make adjustments to store energy made through photosynthesis. Understanding these adjustments could help develop new plants that can withstand rising temperatures from climate change. |

| Maternal diets rich in Omega-3 fatty acids may protect offspring from breast cancer, study suggests Posted: 28 Jun 2021 02:06 PM PDT Researchers noted a significant difference in mice from mothers that were fed a diet rich in canola oil, compared with mothers fed a diet rich in corn oil. A maternal Omega 3-rich diet affected genome-wide epigenetic landscape changes in offspring and potentially modulated gene expression patterns. |
| Weird warbler reveals genetics of its mismatched colors Posted: 28 Jun 2021 02:05 PM PDT An incredibly rare hybrid warbler with mismatched color patterns has allowed researchers to disentangle the genetic drivers of two traits that usually come as a package deal -- the black face mask and the black throat patch in blue-winged and golden-winged warblers. |

| Shock find brings 'extinct' mouse 'back from the dead' Posted: 28 Jun 2021 12:29 PM PDT An Australian mammal thought to have been wiped out over 150 years ago can now be crossed off our list of extinct animals, following a new study. |
| DNA data and modelling reveal potential spread of invasive species Posted: 28 Jun 2021 11:48 AM PDT Scientists have found that a marine invasive species - a sea squirt that lives on rocky shores - could spread along 3,500 kilometers of South American coastline if climate change or human activities alter sea conditions. |
| Unusual prey: Spiders eating snakes Posted: 28 Jun 2021 10:38 AM PDT There are spiders that eat snakes. Observations of snake-eating spiders have been reported around the world. Researchers consolidated and analyzed over 300 reports of this unusual predation strategy. |
| Deep machine learning completes information about the bioactivity of one million molecules Posted: 28 Jun 2021 10:21 AM PDT A newly developed tool predicts the biological activity of chemical compounds, key information to evaluate their therapeutic potential. Using artificial neural networks, scientists have inferred experimental data for a million compounds and have developed a package of programs to make estimates for any type of molecule. |

| New tools for pandemic prevention research: DNA sequencing from water and leeches Posted: 28 Jun 2021 09:49 AM PDT In new research, water from African and Mongolian waterholes as well as bloodmeals from Southeast Asian leeches were assessed for the ability to retrieve mammalian viruses without the need to find and catch the mammals. The scientists analyzed the samples using high-throughput sequencing to identify known viruses as well as viruses new to science. |
| An atlas of the bumblebee brain Posted: 28 Jun 2021 09:30 AM PDT A three-dimensional atlas of the bumblebee brain is now available. It will allow to even better research how nerve cells are interconnected and how they process information. |
| New face mask prototype can detect COVID-19 infection Posted: 28 Jun 2021 08:41 AM PDT Engineers have designed a prototype face mask that can diagnose the person wearing the mask with Covid-19 within about 90 minutes. The technology can also be used to design wearable sensors for a variety of other pathogens or toxic chemicals. |
| Paleonursery offers rare, detailed glimpse at life 518 million years ago Posted: 28 Jun 2021 08:41 AM PDT All life on Earth 500 million years ago lived in the oceans, but scientists know little about how these animals and algae developed. A newly discovered fossil deposit near Kunming, China, may hold the keys to understanding how these organisms laid the foundations for life on land and at sea today, according to an international team of researchers. |
| Don't worry, birds won't become dependent on you feeding them, study suggests Posted: 28 Jun 2021 08:41 AM PDT Researchers have some good news for the well-meaning masses who place bird feeders in their yards: The small songbirds who visit the feeders seem unlikely to develop an unhealthy reliance on them. |
| Males help keep populations genetically healthy Posted: 27 Jun 2021 01:36 PM PDT A few males are enough to fertilize all the females. The number of males therefore has little bearing on a population's growth. However, they are important for purging bad mutations from the population. This is shown by a new study providing in-depth knowledge of the possible long-term genetic consequences of sexual selection. |
| Test distinguishes SARS-CoV-2 from other coronaviruses with 100-percent accuracy Posted: 25 Jun 2021 12:56 PM PDT Researchers have demonstrated a tablet-sized device that can reliably detect multiple COVID-19 antibodies and biomarkers simultaneously. Initial results show the test can distinguish between antibodies produced in response to SARS-CoV-2 and four other coronaviruses with 100-percent accuracy. The researchers are now working to see if the easy-to-use, energy-independent, point-of-care device can be used to predict the severity of a COVID-19 infection or a person's immunity against variants of the virus. |
