Potential regional declines in species richness of tomato pollinators under climate
About 70% of the world's main crops depend on insect pollination. Climate change is already affecting the abundance and distribution of insects, which could cause geographical mismatches between crops and their pollinators. Crops that rely primarily on wild pollinators (e.g., crops that cannot be effectively pollinated by commercial colonies of honey bees) could be particularly in jeopardy. (2021-02-22)

SwRI scientists image a bright meteoroid explosion in Jupiter's atmosphere
From aboard the Juno spacecraft, a Southwest Research Institute-led instrument observing auroras serendipitously spotted a bright flash above Jupiter's clouds last spring. The Ultraviolet Spectrograph (UVS) team studied the data and determined that they had captured a bolide, an extremely bright meteoroid explosion in the gas giant's upper atmosphere. (2021-02-22)

More than half of Earth's rivers strongly impacted by human activity
Few of Earth's freshwater areas remain untouched by humans. More than half of the planet's freshwater river basins have been heavily impacted by human activities, according to a new study, which presents a novel, multi-faceted approach for evaluating biodiversity change at a global scale. (2021-02-18)

Bacteria and algae get rides in clouds
Human health and ecosystems could be affected by microbes including cyanobacteria and algae that hitch rides in clouds and enter soil, lakes, oceans and other environments when it rains, according to a Rutgers co-authored study. (2021-02-16)

Regional variation in the impacts of the COVID-19 pandemic on data collection
The COVID-19 pandemic has changed human behavior, and that has major consequences for data-gathering citizen-science projects such as eBird, run by the Cornell Lab of Ornithology. New research finds that when human behaviors change, so do the data. (2021-02-15)

Once bitten, twice shy: the neurology of why one bad curry could put us off for life
A negative experience with food usually leaves us unable to stomach the thought of eating that particular dish again. Using sugar-loving snails as models, researchers at the University of Sussex believe these bad experiences could be causing a switch in our brains, which impacts our future eating habits. (2021-02-11)

Long-term environmental damage from transportation projects in Kenya, scientists warn
The construction of a major railway through Kenya will have long-term environmental impacts on the area, suggesting more work needs to be done to limit the damage on future infrastructure projects, a major study reveals. (2021-02-09)

Human-generated noise pollution dominates the ocean's soundscape
The soundscapes of the Anthropocene ocean are fundamentally different from those of pre-industrial times, becoming more and more a raucous cacophony as the noise from human activity has grown louder and more prevalent. (2021-02-04)

More than just CO2: It's time to tackle short-lived climate-forcing pollutants
Climate change mitigation is about more than just CO2. So-called 'short-lived climate-forcing pollutants' such as soot, methane, and tropospheric ozone all have harmful effects. Climate policy should be guided by a clearer understanding of their differentiated impacts. (2021-01-27)

In Brazil, many smaller dams disrupt fish more than large hydropower projects
A new paper published Jan. 11 in Nature Sustainability quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution. (2021-01-27)

Prenatal BPA exposure may contribute to the male bias of autism spectrum disorder
Autism has a higher prevalence in males than females. Bisphenol A (BPA) is a common chemical found in plastics, our food, and even the human placenta. Higher prenatal exposure to BPA is thought to increase the risk of autism. Researchers have, for the first time, identified autism candidate genes that may be responsible for the sex-specific effects of BPA. (2021-01-19)

Eggs reveal what may happen to brain on impact
Our brains consist of soft matter bathed in watery cerebrospinal fluid inside a hard skull, and in Physics of Fluids, researchers describe studying another system with the same features, an egg, to search for answers about concussions. Considering that in most concussive brain injuries, the skull does not break, they wanted to find out if it was possible to break or deform the egg yolk without breaking the eggshell. (2021-01-19)

New hard disk write head analytical technology can increase hard disk capacities
Using synchrotron radiation at SPring-8 - a large-scale synchrotron radiation facility - Tohoku University, Toshiba Corporation, and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully imaged the magnetization dynamics of a hard disk drive (HDD) write head for the first time, with a precision of one ten-billionth of a second. The method makes possible precise analysis of write head operations, accelerating the development of the next-generation write heads and further increasing HDD capacity. (2021-01-07)

Surveys identify relationship between waves, coastal cliff erosion
Researchers have always known that waves were an important part of the cliff erosion process, but they haven't been able to separate the influence of waves and rain before. After decades of debate over the differing roles that both play, new findings provide an opportunity to improve forecasts. (2020-12-28)

Shark fishing bans partially effective
Bans on shark fishing are only partially effective in protecting sharks, new research suggests. (2020-12-17)

How water helps the substrate into the enzyme
Researchers from Bochum and Berkeley have investigated why cages can increase the catalytic activity of enclosed molecules. Using terahertz spectroscopy and complex computer simulations, they showed that water encapsulated in a tiny cage has special properties - that are structurally and dynamically distinct from any known phase of water. The water forms a droplet inside the cage that facilitates the encapsulation of a host molecule, i.e. to access the catalytic centre. (2020-12-15)

Silica the best environmental alternative to plastic microbeads, finds study
Following bans on plastic microbeads in wash-off cosmetics, a new study weighs up the environmental costs of alternatives. (2020-12-14)

Recovery of an endangered Caribbean coral from parrotfish predation
Orbicella annularis is an important Caribbean coral and an endangered species, yet it is also frequently predated by parrotfishes. In a recent study published in Coral Reefs, researchers from California Polytechnic State University tracked the recovery of this coral species from parrotfish predation. They found that O. annularis coral tissue loss appears to be driven primarily by a few exceptionally large parrotfish predation scars. Fortunately, 87% of scars were small and likely to fully heal.

Mass extinctions of land-dwelling animals occur in 27-million-year cycle
Mass extinctions of land-dwelling animals--including amphibians, reptiles, mammals, and birds--follow a cycle of about 27 million years, coinciding with previously reported mass extinctions of ocean life, according to a new analysis published in the journal Historical Biology. (2020-12-11)

Impacts of COVID-19 emissions reductions remain murky in the oceans

Way to support effective brain performance after head injury backgrounded by lack of sleep
Scientists from the School of Biomedicine of Far Eastern Federal University (FEFU) with colleagues from Italy, Spain, Romania, and Sweden suggest a way to protect the brain and minimize neurodegenerative processes after concussion head injuries in the presence of extensive previous sleep deprivation. This methodology is especially important given the retirement-age increase that has recently become an international trend. A related article appears in the Progress in Brain Research journal.
