Instead of carrying the babies until they hatched, as in most species of sea spiders, one parent (likely the father) spent two days attaching the eggs to the rocky bottom where they developed for several months before hatching as tiny larvae.
What would be its use? Won’t it violate the provisions of the Outer Space Treaty? What kind of damage can it cause? Do Russia and the U.S. have ASAT capabilities? Why do theories about it also include the nuclear question?
On February 17, 1869, legend has it that Russian chemist and inventor Dmitri Mendeleev conceived and created the table that we now know as the periodic table. While that might be an exaggeration, Mendeleev’s role in creating the table is indisputable. A.S.Ganesh takes a look at how the periodic table came to be…
There is wide variability in the way humans respond to immune challenges, such as bacterial or viral infections, as seen with the diverse range of clinical outcomes observed after infection with SARS-CoV-2
Why is this fuss about these various major varieties of coffee? The answer comes from a recent genetic study of coffee beans
Prevalence of high-risk pregnancies was highest in Meghalaya (67.8%), Manipur (66.7%), Mizoram (62.5%) and Telangana (60.3%), while lowest in Sikkim (33.3%), Odisha (37.3%) and Chhattisgarh (38.1%)
‘The spacecraft has been injected into a very good orbit,’ ISRO Chairman S. Somanath said
You may not realize it, but 'nudge' has been used by businesses, policy-makers and governments for years to prod the public into making different choices. Small changes in our environment can 'nudge' us into different behaviors without restricting the options available to us. For example, printing the low-calorie options in bold on a menu, or showing the calorie information, might change what we choose to eat. But does the public support this?
Anoxic marine basins may be among the most viable places to conduct large-scale carbon sequestration in the deep ocean, while minimizing negative impacts to marine life. As we explore ways to actively draw down the levels of carbon in the atmosphere, sending plant biomass to these barren, oxygen-free zones on the seafloor becomes an option worth considering.
A key step to achieving climate neutrality in the European Union is to rapidly shift from fossil fuels to electric technologies powered by renewable energies, a new study shows. At the same time, hydrogen produced from electricity will also be indispensable in hard-to-electrify sectors such as aviation, shipping and chemicals. By 2050, electrification and hydrogen are the key strategies to reach climate neutrality based on renewable power.
The efficiency of oxygen supply to tissues is a factor in the severity of important diseases such as Covid-19 and heart conditions. Scientists already know that the relationship between the length of a person's index and ring fingers, known as the 2D:4D ratio is correlated with performance in distance running, age at heart attack and severity of Covid-19.
A team of researchers are encouraging us to swap textbooks for games, as they drive the application of games in learning, engagement and research.
A new paradigm is taking shape in the space industry as the countries and entities accessing space continue to grow and diversify. This dynamic landscape creates both competition and potential for scientific collaboration, as well as the challenges and opportunities of progress.
A new study analyzed space and time trends for fine particulate matter (PM2.5) in the continental United States to track the progress of regulatory actions by federal, state and local authorities aimed at curbing air pollution. The team found that while the annual average concentration for PM2.5 had been significantly reduced, its chemical composition had changed during the study period of 2006 to 2020. Their analysis suggests targeted strategies to reduce specific pollutants for different regions of the U.S. may be more effective in further reducing total air pollution and PM2.5 -related adverse health effects. PM2.5, an airborne pollutant, is a mix of multiple chemical species and includes fine particles less than 2.5 microns in size. PM2.5 has been linked to many adverse human health effects including premature death. It also can reduce visibility by creating haze in the air.
A new measure that compares earthquake-related fatalities to a country's population size concludes that Ecuador, Lebanon, Haiti, Turkmenistan, Iran and Portugal have experienced the greatest impact from fatalities in the past five centuries.
Neuroscientists have developed a single-dose genetic medicine that has been proven to halt the progression of both ALS and FTD in mice -- and may even offer the potential to reverse some of the effects of the fatal diseases. It may also hold opportunities for treating more common forms of dementia, such as Alzheimer's disease.
Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is a concern. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. New research reveals a method to more accurately measure, predict and model a key part of the process to make nuclear waste more stable. This could lead to improved nuclear waste treatment facilities and also to new theories about how some heavier elements in the universe came to be.
A research team that had previously succeeded in synthesizing fumaric acid using bicarbonate and pyruvic acid, and carbon dioxide collected directly from the gas phase as one of the raw materials, has now created a new photosensitizer and developed a new artificial photosynthesis technology, effectively doubling the yield of fumaric acid production compared to the previous method. The results of this research are expected to reduce carbon dioxide emissions and provide an innovative way to produce biodegradable plastics while reusing waste resources.
