Indian authorities may have exaggerated claims of rising tiger numbers
India’s government claims that the population of tigers in India has reached 2,967 animals – more than a doubling of the 1,411 animals reported in 2006. But there is a problem: The conclusion is not backed by reliable evidence, according to a new scientific paper.
Slow loris study reveals: The human rhythm of sleep can be much older than expected
The Javan slow loris is a small, furry, big-eyed and apparently cute primate, but the bite is poisonous! A new study shows that the lorises sleep in the same way as humans do, and this indicates that the so-called monophasic sleep pattern is a much older evolutionary trait than previously assumed.
New map of the seabed reveal more deposits than expected
There are 30 % more sediments on the seabed than previously expected, reveal an update of the map GlobSed. This equates to up to two kilometers of extra land mass over today’s land area.
European mega-venture for safe medications during pregnancy
“It takes an estimated 27 years to determine if a novel medication can be used by pregnant women without risking adverse effects on the fetus or child. This just can’t continue any longer”, says Professor Hedvig Nordeng at the University of Oslo’s Department of Pharmacy.
A novel antibiotic idea: Preventing bacterial stickiness
Antibiotics most commonly work by killing bacteria, for example by destroying their cell wall or by interfering with protein synthesis. Now researchers at UiO are launching a completely new idea: They want to prevent bacteria from sticking to a substrate, before an infection can even occur.
Deep-sea fish see color in pitch-black darkness
Humans, along with many other mammals, must make do with four different light-sensitive proteins in the rods and cones of our retinas. However, fish species living in the deep sea can have up to 40 different proteins aiding their vision. This means that they most likely see some sort of color where humans would only see pitch-black darkness.
Exhaust gas is to blame: Ground-level ozone is damaging crops
Exhaust gas emissions have doubled the amount of ground-level ozone. Vegetation is being destroyed. Food production is decreasing. Researchers now fear that the damage is greatest in the Arctic regions.
Melting glaciers are causing sea levels to rise at ever greater rates
New data and analysis show that land-based glaciers outside of the main ice sheets in Antarctica and Greenland have lost more than 9,000 billion tons of ice since 1961, raising sea levels by 27 millimeters.
Salt's love of water can play a key role in safe CO₂ storage
Salt precipitation, which creates trouble when injecting CO2 into porous stone, has the potential to clog leakage pathways in the caprocks.
Widespread and maybe risky use of herbal medicines among pregnant women in Ethiopia
A study of Ethiopian women’s use of traditional medicinal plants during pregnancy has come up with several surprises. The most worrisome is that most women don’t tell their doctors about the practice.
