Lunar dynamo's lifetime extended by at least 1 billion yearsNew evidence from ancient lunar rocks suggests that an active dynamo once churned within the molten metallic core of the moon, generating a magnetic field that lasted at least 1 billion years longer than previously thought. Dynamos are natural generators of magnetic fields around terrestrial bodies, and are powered by the churning of conducting fluids within many stars and planets. In a paper published today in Science Advances, researchers from MIT and Rutgers University report that a lunar rock collected by NASA's Apollo 15 mission exhibits signs that it formed 1 to 2.5 billion years ago in the presence of a relatively weak magnetic field of about 5 microtesla. That's around 10 times weaker than Earth's current magnetic field but still 1,000 times larger than fields in interplanetary space today. | |
Four Earth-sized planets detected orbiting the nearest sun-like starA new study by an international team of astronomers reveals that four Earth-sized planets orbit the nearest sun-like star, tau Ceti, which is about 12 light years away and visible to the naked eye. These planets have masses as low as 1.7 Earth mass, making them among the smallest planets ever detected around nearby sun-like stars. Two of them are super-Earths located in the habitable zone of the star, meaning they could support liquid surface water. | |
Chaco Canyon petroglyph may represent ancient total eclipseAs the hullabaloo surrounding the Aug. 21 total eclipse of the sun swells by the day, a University of Colorado Boulder faculty member says a petroglyph in New Mexico's Chaco Canyon may represent a total eclipse that occurred there a thousand years ago. | |
The mystery of the pulsating blue starsIn the middle of the large Chilean Atacama desert, a team of Polish astronomers are patiently monitoring millions of celestial bodies night after night with the help of a modern robotic telescope.

A personalized approach to Alzheimer's disease preventionAlzheimer's disease (AD) is a type of dementia that causes problems with memory, thinking, and behavior. It affects more than 5 million Americans. The Alzheimer's Association estimates that some 16 million people will develop the disease by the year 2050 if an effective treatment is not discovered. Symptoms of AD usually develop slowly and worsen over time. They often become severe enough to interfere with daily tasks, and can eventually cause death. | |

Fruit fly mutation foretells 40 million years of evolutionSmall, seemingly insignificant mutations in fruit flies may actually hold clues as to how a species will evolve tens of millions of years in the future. | |
Eradicating exotic pests with 'infertility genes' may be possibleUniversity of Adelaide researchers have shown that it may be possible to eradicate populations of invasive pest animals through the inheritance of a negative gene - a technique known as gene drive. | |
Penguin forensics: Tracking the winter whereabouts of penguins by analyzing tail feathersKnowing where and how Antarctic penguins, and other seabirds and marine predators, migrate is critical for conservation efforts. Although electronic tracking devices have helped scientists track marine animals' migration patterns, the devices can be expensive, invasive for the animal and challenging to retrieve. Scientists have discovered a new and potentially better way to track where penguins go over the winter using forensics. | |
Ants dominate waste management in tropical rainforestsA study by the University of Liverpool, in collaboration with the Natural History Museum, has found that ants are responsible for moving more than half of food resources from the rainforest floor, playing a key role in maintaining a healthy ecosystem. | |
Increased floodlighting reducing bat populations in Sweden's churches(Phys.org)—A trio of researchers, two from Sweden and one from Spain has found that installing floodlighting around rural churches drives away roosting bats. In their paper published in Royal Society Open Science, Jens Rydell, with Lund University, Johan Eklöf, with Graptolit Ord och Natur and Sonia Sánchez-Navarro with Estación Biológica de Doñana-CSIC describe their comparison of church bat populations over the course of several decades. | |
Fossil evidence suggests humans played a role in monkey's demise in JamaicaRadiocarbon dating of a fossilized leg bone from a Jamaican monkey called Xenothrix mcgregori suggests it may be the one of the most recent primate species anywhere in the world to become extinct, and it may solve a long-standing mystery about the cause of its demise. The short answer: human settlement of its island home. | |
The color of people's clothing affects lizard escape behaviorThe color of T-shirts people wear affects escape behavior in western fence lizards, according to a study published August 9, 2017 in the open-access journal PLOS ONE by Breanna Putman from University of California, Los Angeles and the Natural History Museum of Los Angeles County, U.S.A., and colleagues. | |
Family break-ups lead to domestic violence in fruit fly relationshipsMale fruit flies with strong family ties are less likely to become abusive during mating than others, according to new Oxford research. | |
Defining standards for genomes from uncultivated microorganismsDuring the Industrial Revolution, factories began relying on machines rather than people for mass production. Amidst the societal changes, standardization crept in, from ensuring nuts and bolts were made identically to maintain production quality, to a standard railroad gauge used on both sides of the Atlantic. The importance of standards is dramatically illustrated when they don't exist or are not commonly accepted, e.g., Macs, vs. PCs, or even pounds vs. kilograms. | |
Too near, or too far? What fruit flies teach us about personal spaceMost of us have had the experience of backing away when someone has stepped inside the bounds of our personal space. But, until now, little has been understood about the mechanisms that allow us to determine when someone is "too near" or "too far". | |
Prairie-chicken nests appear unaffected by wind energy facilityWind energy development in the Great Plains is increasing, spurring concern about its potential effects on grassland birds, the most rapidly declining avian group in North America. However, a new study from The Condor: Ornithological Applications suggests that for one grassland bird species of concern—the Greater Prairie-Chicken—wind energy infrastructure has little to no effect on nesting. Instead, roads and livestock grazing remain the most significant threats to its successful reproduction. | |
'Gene drives' could wipe out whole populations of pests in one fell swoopWhat if there was a humane, targeted way to wipe out alien pest species such as mice, rats and rabbits, by turning their own genes on themselves so they can no longer reproduce and their population collapses? | |
Invasive gobies may change Oneida Lake's complexion—againOneida Lake, a kissing cousin to New York's Finger Lakes, may soon get an environmental makeover due to another in a series of invasive species bringing havoc to the body's ecosystem and disturbing its recreational waters. | |
Parasites, snails may factor in Adirondack moose declineThe apparent declining moose population in New York 's Adirondack Mountains may be caused partly by tiny parasite-transmitting snails eaten by moose as they forage vegetation, according to new research presented by two Cornell undergraduate students at the annual Ecological Society of America meeting, in Portland, Oregon, Aug. 8. | |
Novel poxvirus threatens juvenile squirrelsA previously unknown poxvirus causes severe disease in European red squirrels from Germany. Molecular genetic investigations revealed a new virus species in the family of Poxviridae. Results of the study are published in the scientific journal Emerging Infectious Diseases. | |
How to save zoos? Focus on education, conservationOne of my earlier memories from my childhood is visiting the Frankfurt zoo in Germany. I watched several elephants in an indoor enclosure, and while they were huge and fascinating, it also saddened me to see such magnificent animals in captivity. I also remember having straw thrown in my face by one of those elephants, although my parents dispute this. | |
Genetics takes fight to gardeners' green foeA scientist from The University of Manchester has hit upon an innovative way to control greenflies which infest our gardens and farms. | |
Why abseiling spiders don't spin out of control—new researchSeeing an abseiling spider descend gracefully using its dragline silk instead of spinning unpredictably and uncontrollably, led us to try and understand the science behind it. | |
Spying on malaria parasites at -196 CelsiusMalaria research: By combining two advanced microscope techniques an international team of scientists led by postdoc Sergey Kapishnikov from the Niels Bohr Institute has managed to obtain new information about the ravaging mode of operation applied by malaria parasites when attacking their victims. This information can be utilized when designing new medication to more effectively fight malaria - a disease claiming over 400.000 lives each year, a majority of whom are infants. | |
Researchers detail one of the biggest proteins ever foundA bacterium living in the icy-cold waters of Antarctica manages to survive by gripping on to the ice surface. The protein used by the bacterium to do this—a kind of extendable anchor—has been detailed by a group of researchers from Eindhoven University of Technology (TU/e), Queen's University (Canada) and the Hebrew University of Jerusalem (Israel). Quite special, because at 600 nanometers, it is one of the biggest proteins for which the structure has ever been identified. Useful too, because knowledge about how bacteria attach themselves is helpful if you want to prevent this, for example, in pathogenic bacteria that grip on to human cells in a similar way. | |
Understanding salamander breeding patterns may lead to better forest management, conservation strategiesWith changing environments, pond-breeding salamanders face increasingly hazardous treks as the space between breeding ponds and their non-breeding habitat widens or is degraded. A study from the University of Missouri suggests that a salamander's success may depend more on when it breeds than on the landscape obstacles it might face. Scientists believe that knowing the patterns in which salamanders move back and forth could lead to better forest management and conservation strategies. | |
Researchers examine contaminants in hunted wildlifeConcerning environmental contaminants, game species are not subject to the same safety testing as commercially marketed livestock. A recent study sampled feral pigs, gray squirrels, and waterfowl from relatively uncontaminated habitats and areas of contamination. | |
Rogue elephant tramples 15 to death in India, faces cullingAn elephant that has killed 15 people in eastern India over a months-long rampage could be shot within days if it is not brought under control, an official said Wednesday. | |
How to kill fruit flies, according to a scientistAs a researcher who works on fruit flies, I often get asked how to get them out of someone's kitchen. This happens to fly researchers often enough that we sit around fly conferences (these actually exist) and complain about getting asked this question. | |
Loggerhead sea turtle released after rehabA loggerhead sea turtle that was rescued in Virginia and named Humphrey has been released back into the ocean after undergoing rehabilitation in New Jersey. | |
Feds probed anglers linked to shark-dragging but closed case last yearFederal wildlife agents who last year investigated a group of Gulf coast anglers linked to a brutal shark-dragging video were foiled by uncooperative witnesses and an inability to confirm when the illegal acts occurred. | |
Researchers are undertaking two projects that will inform the oil platform decommissioning process in CaliforniaWhen the Colorado-based oil company Venoco, Inc.—founded in Carpinteria, California, more than two decades ago—declared bankruptcy last spring and ceded its offshore lease, the state of California "inherited" 50-year-old Platform Holly off the coast of Santa Barbara. |
