Biological ‘clock’ discovered in sea turtle shells


In addition to their natural beauty, the shells of two deceased specimens of Hawksbill sea turtles hold clues to the growth rates and sexual maturity of the endangered species.
Radiocarbon dating of atomic bomb fallout found in sea turtle shells can be used to reliably estimate the ages, growth rates and reproductive maturity of sea turtle populations in the wild, a new study led by Duke University and NOAA researchers finds.

Hacking the programs of cancer stem cells


A new inhibitor suppresses tumor growth and cancer stem cells. The image on the left shows beta catenin (red) in cell nuclei indicating that these are cancer stem cells.
All tumor cells are the offspring of a single, aberrant cell, but they are not all alike. Only a few retain the capacity of the original cell to create an entire tumor. Such cancer stem cells can migrate to other tissues and become fatal metastases. To fully cure a patient’s cancer, it is crucial to find and eliminate all of these cells because any that escape can regenerate the tumor and trigger its spread through the body.

Researchers set out path for global warming reversal

Bioenergy with carbon capture and storage (BECCS) can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially overshoot this target.

All about LiFi technology

 Li-Fi technology
Li-fi or light fidelity is a wireless technology which was discovered by physicist and professor Herald Haas. It uses visible light instead of radio waves to transmit date rate at speed of Tb (Tera bytes). It is a green technology and has a future access scope.
