Antibiotic Use in Infancy May Increase Risk of Childhood Asthma
Children who receive antibiotics within the first six months of life are at a significantly increased risk of developing asthma and allergies by 6 years of age, even without a genetic predisposition, new research by the Yale School of Public Health suggests. The findings are reported online in the American Journal of Epidemiology. (more…)
Scientists Now Know Why Some Cancers Become Malignant and Others Don’t
Cancer cells reproduce by dividing in two, but a molecule known as PML limits how many times this can happen, according to researchers lead by Dr. Gerardo Ferbeyre of the University of Montreal’s Department of Biochemistry. The team proved that malignant cancers have problems with this molecule, meaning that in its absence they can continue to grow and eventually spread to other organs. Importantly, the presence of PML molecules can easily be detected, and could serve to diagnose whether a tumor is malignant or not. (more…)
Prehistoric Bird Used Club like Wings as Weapon
Long before the knights of medieval Europe wielded flails or martial artists brandished nunchucks, it appears that a flightless prehistoric bird used its own wings as a similar type of weapon in combat. (more…)
What Triggers Mass Extinctions? Study Shows How Invasive Species Stop New Life
*Collapse of Earth’s marine life 378 to 375 million years ago holds key*
An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published in the journal PLoS ONE.
The study of the collapse of Earth’s marine life 378 to 375 million years ago suggests that the planet’s current ecosystems, which are struggling with biodiversity loss, could meet a similar fate. (more…)
Fossilised Tooth Changes Human History?
A research article presented by an Israeli team has unearthed new evidence on the history of the human being – namely that Homo sapiens may be far, far older than we imagined. A research team from the University of Tel Aviv has discovered fossilised teeth 400,000 years old. (more…)
Genome of Extinct Siberian Cave-dweller Linked to Modern-day Humans
Sequencing of ancient DNA reveals new hominin population that is neither Neanderthal nor modern human
Researchers have discovered evidence of a distinct group of “archaic” humans existing outside of Africa more than 30,000 years ago at a time when Neanderthals are thought to have dominated Europe and Asia. But genetic testing shows that members of this new group were not Neanderthals, and they interbred with the ancestors of some modern humans who are alive today. (more…)
Mars Movie: I’m Dreaming of a Blue Sunset
A new Mars movie clip gives us a rover’s-eye view of a bluish Martian sunset, while another clip shows the silhouette of the moon Phobos passing in front of the sun.
America’s Mars Exploration Rover Opportunity, carefully guided by researchers with an artistic sense, has recorded images used in the simulated movies.
These holiday treats from the rover’s panoramic camera, or Pancam, offer travel fans a view akin to standing on Mars and watching the sky. (more…)
