Paleontologists debunk fossil thought to be missing link between lizards and first snakes
Filling in the links of the evolutionary chain with a fossil record of a ‘snake with four legs’ connecting lizards and early snakes would be a dream come true for paleontologists. But a specimen formerly thought to fit the bill is not the missing piece…
Extreme heat events jeopardize cardiovascular health, experts warn
A consequence of global warming is a greater frequency and intensity of extreme heat events. This extreme heat is associated with a greater risk of adverse cardiovascular incidents, especially for adults with pre-existing cardiovascular diseases.
New findings on the link between CRISPR gene-editing and mutated cancer cells
A protein that protects cells from DNA damage, p53, is activated during gene editing using the CRISPR technique. Consequently, cells with mutated p53 have a survival advantage, which can cause cancer. Researchers have found new links between CRISPR, p5…
‘Surgery selfies’ could spot serious infections early
Smartphone pictures of post-surgical wounds taken by patients and then assessed by clinicians can help with the early identification of infections, a study has found.
Study links stress to Crohn’s disease flare-ups
Researchers using mouse models found that stress hormones suppressed the innate immune system that normally protects the gut from invasive Enterobacteriaceae, a group of bacteria including E. coli which has been linked to Crohn’s disease.
Earthquakes and extreme rainfall lead to a significant increase in the rates of landslides in Nepal
Researchers outline how they were able to establish a clear pattern between the strength of the monsoon season in Nepal and the amount of landsliding over a 30-year period between 1988 and 2018.
Warmer soil stores less carbon
Global warming will cause the world’s soil to release carbon, new research shows.
Plumbing the depths: Defect distribution in ion-implanted SiC diodes
Introducing a vertical arrangement of n and p layers into the drift layer of semiconductors to enable bipolar operation is a way around the ‘unipolar limit’ problem in semiconductors. But defect generation during the fabrication of such devices is a ma…
120-year-old reaction turned on its head with environment-friendly, paste-based method
A new method for creating one of chemistry’s most widely used class of compounds could revolutionize industrial processes, making them cheaper, simpler and more environmentally friendly.
Scientist advances prospect of regeneration in humans
In a study that builds on earlier research that identified macrophages as essential to regeneration in the axolotl, a highly regenerative salamander, a scientist has identified the source of these critical white blood cells as the liver. By giving scie…
Different kinds of marine phytoplankton respond differently to warming ocean temperatures
A team of researchers has concluded that different types of phytoplankton will react differently to increasing ocean temperatures resulting from the changing climate. An examination of how four key groups of phytoplankton will respond to ocean temperat…
