| Posted: 01 Nov 2021 04:08 PM PDT A new study that modeled changes in the world's 45 different 'life zones' from climate change revealed that climate impacts may soon triple over these areas if the earth continues 'business-as-usual' emissions. |
| Posted: 01 Nov 2021 04:08 PM PDT Researchers have shown that antibody levels against SARS-CoV-2 (the COVID-19 virus) stay more durable -- that is, remain higher over an extended period of time -- in people who were infected by the virus and then received protection from two doses of messenger RNA (mRNA) vaccine compared with those who only got immunized. |
| Researchers move closer to controlling two-dimensional graphene Posted: 01 Nov 2021 02:12 PM PDT New results relied on a cleaner technique to manipulate the flow of electricity, giving graphene greater conductivity than metals such as copper and gold, and raising its potential for use in telecommunications systems and quantum computers. |
| Study casts doubt on theory that women aren't as competitive as men Posted: 01 Nov 2021 12:48 PM PDT The theory has been touted as a possible explanation for America's longstanding gender wage gap. But new research suggests women exhibit their competitiveness differently. |
| The silent build-up to a super-eruption Posted: 01 Nov 2021 12:48 PM PDT It is estimated that about 5-10 volcanoes worldwide are capable of producing a super-eruption that could catastrophically affect global climate. One of these volcanoes hides below the waters of Lake Toba in Sumatra and has caused two super-eruptions in the last one million years. But when will the next one be? Will there be any warning signs? To answer these questions, an international team of geologists developed an analysis of the levels of uranium and lead in zircons -- a mineral typically found in explosive volcanic eruptions -- to determine how long it took the volcano to prepare for its super-eruptions. |
| Researchers discover predictable behavior in promising material for computer memory Posted: 01 Nov 2021 11:18 AM PDT A team of researchers has discovered unexpectedly familiar behavior in the antiferroelectric material known as zirconium dioxide, or zirconia. |

| Study shows how 1.5°C temperature rise can cause significant changes in coastal species Posted: 01 Nov 2021 11:17 AM PDT As COP26 leaders gather in the UK, new research shows a temperature increase of around 1.5°C -- just under the maximum target agreed at the COP23 Paris meeting in 2017 -- can have a marked impact on algae and animal species living on our coastlines. |
| Posted: 01 Nov 2021 11:17 AM PDT Monoclonal antibodies protected aged, diabetic rhesus macaque monkeys from disease due to SARS-CoV-2 and reduced signs of inflammation, including in cerebrospinal fluid, according to a new study. |
| Posted: 01 Nov 2021 11:17 AM PDT The mid-ocean 'twilight zone' holds the key to several tantalizing questions about the marine food web and carbon-sequestering capacity of the ocean. But studying this vast and remote area is extremely difficult. Many inhabitants of the twilight zone are easily destroyed during sampling -- or are quick to avoid any disturbance -- so it's difficult to sample them with traditional nets. Advances in acoustics have enabled more accurate estimates of biomass, but questions about the diversity and distribution of species within that biomass remain unanswered. |
| Sperm switch swimming patterns to locate egg Posted: 01 Nov 2021 11:17 AM PDT A new study reveals how sperm change their swimming patterns to navigate to the egg, shifting from a symmetrical motion that moves the sperm in a straight path to an asymmetrical one that promotes more circular swimming. |
| How bread wheat got its gluten: Tracing the impact of a long-lost relative on modern bread wheat Posted: 01 Nov 2021 11:17 AM PDT Genetic detective work has uncovered an obscure ancestor of modern bread wheat, in a finding similar to uncovering a famous long-lost relative through DNA analysis in humans. |
| Uncovering the secrets behind Earth’s first major mass extinction Posted: 01 Nov 2021 11:15 AM PDT New research reveals more information about the first and oldest of the 'big five' extinctions. Around 85% of marine species, most of which lived in shallow oceans near continents, disappeared during that time. |
| New type of nerve cell discovered in the retina Posted: 01 Nov 2021 07:54 AM PDT Scientists have discovered a new type of nerve cell, or neuron, in the retina. In the central nervous system a complex circuitry of neurons communicate with each other to relay sensory and motor information; so-called interneurons serve as intermediaries in the chain of communication. |
| Snakes more likely to inbreed and lose ability to adapt due to urbanization Posted: 01 Nov 2021 07:54 AM PDT New research has found that isolated Perth tiger snake populations, such as those surrounded by urban development or seawater, are more likely to resort to inbreeding than those in less 'cut off' communities. |
| A reef in two gears: New patterns of coral recovery discovered Posted: 01 Nov 2021 07:54 AM PDT Combining an innovative approach developed for medical sciences mathematicians and marine ecologists have identified new coral recovery patterns in the Great Barrier Reef, providing critical information for the management of the reef. |
| The 5:2 diet: A good choice for gestational diabetes Posted: 01 Nov 2021 07:54 AM PDT Weight loss after gestational diabetes can prevent the onset of type 2 diabetes. Yet finding the most effective way to lose weight and keep it off can be a challenge, especially for mothers with a new baby. Now, new research suggests that the popular 5:2 or intermittent fasting diet is just as effective as a conventional energy-restricting diet, enabling women greater choice and flexibility when it comes to weight loss. |
| Posted: 01 Nov 2021 07:54 AM PDT New research addresses the misconception that children are less susceptible to infection with the new coronavirus. According to a recent report, children and adults have similar risks of becoming infected with SARS-CoV-2, but a much larger proportion of infected children do not show symptoms of COVID-19. When one household member is infected, there is a 52 percent chance they will transmit it to at least one other person with whom they live. |
| Posted: 01 Nov 2021 07:54 AM PDT Color centers are lattice defects in crystals that can capture one or more additional electrons. The spin of these electrons is very sensitive to external electric and magnetic fields -- and to sound. Researchers are now reporting the selective manipulation of electron spins in both their ground and excited states with sound. Their approach opens the path to new methods for processing quantum information inaccessible so far. |
| Noninvasive imaging strategy detects dangerous blood clots in the body Posted: 01 Nov 2021 07:54 AM PDT Investigators have developed and tested a targeted contrast agent that can detect blood clots in the hearts of patients with atrial fibrillation, or an irregular heartbeat. The strategy could be used to find clots in other parts of the body as well, such as in vessels that, when blocked, can lead to stroke. |
| Study IDs strategies to help recovering alcoholics Posted: 01 Nov 2021 07:53 AM PDT A new study identified six strategies recovering alcoholics use to negotiate social situations and remain sober. |
| Spintronics: Exotic ferromagnetic order in two-dimensions Posted: 01 Nov 2021 07:53 AM PDT An international team has detected an unusual ferromagnetic property in a two-dimensional system, known as 'easy-plane anisotropy.'
