Climate change increased odds of recent deadly heat in India, Pakistan, scientists say
South Asia’s deadly heatwave in March and April was made 30 times more likely because of climate change, scientists reported Monday. As April temperatures hit nearly 50 degrees Celsius (122 degrees Fahrenheit) in parts of northern India and Pakistan, at least 90 people died from heat-related causes, officials have said. The heatwave, which had delivered record temperatures in India in March, also badly damaged the country’s winter wheat crop.
Scientists make way for gene-edited tomatoes as vegan source of vitamin D
If British scientists have their way, two medium-sized tomatoes a day could keep the doctor away. A research team led by scientists at the John Innes Center in Norwich has edited the genetic makeup of tomatoes to become a robust source of vitamin D, which regulates nutrients like calcium that are imperative to keeping bones, teeth, and muscles healthy.
Ancient massive ‘Dragon of Death’ flying reptile dug up in Argentina
Argentine scientists discovered a new species of a huge flying reptile dubbed “The Dragon of Death” that lived 86 million years ago alongside dinosaurs, in a find shedding fresh insight on a predator whose body was as long as a yellow school bus. The new specimen of ancient flying reptile, or pterosaur, measured around 30 feet (9 meters) long and researchers say it predated birds as among the first creatures on Earth to use wings to hunt its prey from prehistoric skies.
Climate action on CO2 emissions alone won’t prevent extreme warming – study
To control climate change, the world must go beyond cutting carbon dioxide emissions and curb lesser-known pollutants such as nitrous oxide playing a key role in warming the planet, new research suggests. Decades of global climate discussions have focused on CO2 emissions, which are most abundant in the atmosphere. The common goal of reaching “net-zero” emissions refers most often to CO2 emissions alone.
Omicron breakthrough infections may spare young hearts; no need to delay mammogram after vaccination
The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. Omicron breakthrough infections may spare young hearts
