Antidepressants may create antibiotic resistance Antidepressants may cause bacteria to become resistant to antibiotics, according to a study exposing the bacterium E. coli to five common antidepressants. Researchers need to further explore the effect, which was found in Petri dishes, to study whether these antidepressants can cultivate superbugs in the human body or natural environment […]
Several genes play a role in whales’ enormous size Biologists have identified evolutionary changes in DNA that allowed whales to grow larger over time. The researchers found that despite having bigger bodies with more chances for cancer to develop in cells, whales have genes that not only contribute to body size but reduce the impacts […]
Scientists find aging mechanism — and how to reverse it Biologists have developed a new model for understanding aging based on the degradation in how DNA is organized and regulated, identifying the epigenome as the predominant factor in the aging process. The findings may help scientists develop treatments to reverse aging and delay the onset […]
Over two-thirds of world’s glaciers will melt by 2100 More than two-thirds of the world’s glaciers will disappear by 2100 if the climate continues to warm at current trends. The global temperature is on track to rise 2.7 degrees Celsius over pre-industrial levels by the end of the century, but scientists note that if future […]
Bering Land Bridge formed surprisingly late during last ice age A new study shows that the Bering Land Bridge, the strip of land that once connected Asia to Alaska, emerged far later during the last ice age than previously thought. Full Story: Princeton University Exotic clasts in Chang’e-5 samples indicate unexplored terrane on moon The […]
NASA ends Mars InSight lander mission after 4 years NASA has officially concluded its InSight lander mission on Mars after the spacecraft’s solar panels accumulated too much dust and has stopped transmitting information on the planet’s geologic makeup and activity. After an “enormously successful mission,” InSight is “going to sit on Mars and enjoy the […]
Astronomers identify 2 planets as possible water worlds Using data from the Kepler, Hubble and Spitzer space telescopes, astronomers have identified two exoplanets orbiting a red-dwarf star 218 light-years away suspected of being made mostly of water. “It is the first time we observe planets that can be confidently identified as water worlds, a type […]
Radioactive meteorites could have brought life to Earth The gamma rays produced by carbonaceous chondrites, radioactive meteorites that contain water and organic compounds, could have been sufficient to spark the chemical reactions that created amino acids, the building blocks of life on Earth, researchers have concluded. The study is based on observations from bombarding chemicals […]
Flash thought to result from black hole swallowing a star Two separate teams of scientists, who have published papers in Nature and Nature Astronomy, have concluded that a flash of light that appeared in February was the astrophysical jet that erupted from a massive black hole as it swallowed a star. “From the data we […]
Best-explored planet outside our solar system WASP-39b, a boiling Saturn-like planet 700 light-years away from the sun has become the best-explored planet outside our solar system, as the James Webb Space Telescope’s observations have yielded a trove of information about the exoplanet’s atmosphere. Laura Kreidberg, director of the Max Planck Institute for Astronomy, said the […]
