The research team is also assessing the effects of conservation efforts on preserving and recovering these important ecosystems. |
| Warming climate will increase number of harmful algae blooms Posted: 28 Oct 2021 11:36 AM PDT A new study shows how changes in light conditions have a significant influence on the growth and impact of harmful algae blooms. The bottom line: a warming climate looks good for the growth of toxic algae and may disrupt other organisms that are part of the food web -- whether they graze on this algae or are consumed by it. |
| Feedback, goal-setting improve attention Posted: 28 Oct 2021 11:36 AM PDT For individuals to sustain their attention on a task over a long period of time, goal-setting is effective but receiving feedback produces a much stronger effect, according to a new study. |
| New species of human ancestor named: Homo bodoensis Posted: 28 Oct 2021 11:36 AM PDT Palaeoanthropologists have announced the naming of a new species of human ancestor, Homo bodoensis. This species lived in Africa during the Middle Pleistocene, around half a million years ago, and was the direct ancestor of modern humans. |
| After California’s 3rd-largest wildfire, deer returned home while trees were ‘still smoldering’ Posted: 28 Oct 2021 11:36 AM PDT While many animals have adapted to live with wildfires of the past -- which were smaller, more frequent and kept ecosystems in balance across the West -- it's unclear to scientists how animals are coping with today's unprecedented megafires. A team of researchers tracked a population of black-tailed deer before, during and after the 2018 Mendocino Complex Fire and found that most of the deer returned home within hours of the fire, while trees were still smoldering. |

| Best water treading technique to prevent drowning Posted: 28 Oct 2021 09:04 AM PDT Unless you're a water-polo player, the 'egg-beater' technique may mean little to you. But new research has found it may be the most effective skill you can learn to prevent drowning. |
| Stacking the deck: Layers of crystalline nanosheets enable tunable electronic properties Posted: 28 Oct 2021 09:04 AM PDT Researchers have obtained and characterized two-dimensional (2D) boron monosulfide (BS) nanosheets. The bandgap energy of a single BS nanosheet was greater than that of the bulk material from which it came. As additional 2D layers were stacked, the bandgap energy eventually decreased to that of the bulk material. This result reflected the tunable electronic properties of BS nanosheets, which are suitable for electronic devices and photocatalytic applications. |

| Heatwaves like ‘the Blob' could decrease role of ocean as carbon sink Posted: 28 Oct 2021 09:03 AM PDT Researchers have found the two-year heatwave known as 'the Blob' may have temporarily dampened the Pacific's 'biological pump,' which shuttles carbon from the surface ocean to the deep sea where it can be stored for millennia. |
| Trapping molecules to find new physics Posted: 28 Oct 2021 09:03 AM PDT The Standard Model of particle physics has been extremely successful in describing how the universe works. However, there are some things that it cannot explain. Physicists have, therefore, been looking for new physics in particle accelerators such as the Large Hadron Collider at CERN. Now, a different approach is also being used: in contrast to smashing up matter at high energies, physicists wanted to study molecules that are brought to rest. |

| Industry must prepare now for a new world of green electricity Posted: 27 Oct 2021 06:18 PM PDT Industry must speed up investment in new technologies that allow manufacture of materials using renewable electricity if net zero emissions targets are to be met, research warns. The study cautions that national strategies for replacing fossil fuels with renewables need an integrated approach to energy use and material production -- or risk industry being unable to use electricity produced from renewable sources. |
| Burning and tingling in your feet? You may have small fiber neuropathy Posted: 27 Oct 2021 02:26 PM PDT The number of people experiencing numbness, tingling and pain in their feet with no known cause has been increasing over the last two decades, according at a new study.

| The upside-down orbits of a multi-planetary system Posted: 27 Oct 2021 09:21 AM PDT When planets form, they usually continue their orbital evolution in the equatorial plane of their star. However, an international team, led by astronomers from the University of Geneva (UNIGE), Switzerland, has discovered that the exoplanets of a star in the constellation Pisces orbit in planes perpendicular to each other, with the innermost planet the only one still orbiting in the equatorial plane. Why so? This radically different configuration from our solar system could be due to the influence of a distant companion of the star that is still unknown. This study, to be read in the journal Astronomy & Astrophysics, was made possible by the extreme precision achieved by ESPRESSO and CHEOPS, two instruments whose development was led by Switzerland. |
| A novel solution to a combinatorial optimization problem in bicycle sharing systems Posted: 27 Oct 2021 09:21 AM PDT Bicycle sharing systems have become an attractive option to alleviate traffic in congested cities. However, rebalancing the number of bikes at each port as time passes is essential, and finding the optimal routing paths for the vehicles in charge of rebalancing constitutes a combinatorial optimization problem. Now, scientists propose an innovative algorithm that can find near-optimal solutions more quickly even for a large number of ports, paving the way for more efficient bicycle sharing systems. |
