The cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells, and in most of the cases develop into malignant masses of tissues called tumors, and it is the leading causes of mortality and a major public health challenge worldwide. In normal body, genes in the cell nucleus, containing long strings of DNA (deoxyribonucleic acid) regulate the controlled division and function of cells and any damage to DNA causes the mutation of genes, which in turn triggers the uncontrolled division of abnormal cells, leading to the damage of vital organs. Cancer cells can detach from the original mass of tumor and migrate to new locations through blood and lymphatic system and also cancer cells produce enzymes that are capable of breaking the normal cells. For cancer diagnostics, the conventional histopathological and radiological examinations are still used for evaluating the clinical and pathologic staging, needed for cancer treatments. Depends on the stage of cancer development, different treatment options like chemotherapy, radiation therapy, stem cell transplant, immunotherapy, hormone therapy, targeted drug therapy and surgery are advised. The major disadvantages of the available advanced treatment options include non localized invasion to other body parts, intolerable cytotoxicity, unsystematic distribution of antitumor agents, immune to chemical agents, low bioavailability and limited option to evaluate the tumor cell response to therapies^4,5. In spite of the drawbacks of these advanced treatment options, cancer is curable if it is diagnosed at an early stage.

Phototherapy has been used for the treatment of jaundice, cancer, dermatological conditions, and ophthalmological disorders by simply using the light of certain selected wavelength. Photodynamic therapy, on the other hand is a method of photosensitizing the action of drugs to kill cancer cells, but the major drawback of this treatment is that most of the drugs used for photodynamic therapy remain activated for a long time, leading to overdose to damage non cancer cells. In the photo-catalytic process, no drug is used, instead the nontoxic semiconductor photo-catalyst like WO₃ generates electron hole pairs, when it is exposed to the light of appropriate wavelength and these photo-generated charge carriers mediate oxidation and reduction reactions in the cancer cell to eliminate them.

New research, led by scientists at the University of Cambridge, suggests spontaneous DNA mutations that occur when a baby’s brain is growing in the womb may help explain why so many people develop dementia without having any prior family history with the disease.

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week’s contribution is from Beth Bartel and Tim Dittman, from the non-profit UNAVCO consortium in Boulder, Colorado.

About 18 miles west of the Yellowstone National Park boundary in Idaho, UNAVCO field engineer Tom Lyman surveys the damage at GPS station P361 on Sawtell Peak. This is an important site, not only because it is located close to active faults in the Yellowstone region, but also because it serves as a data relay for four additional nearby GPS stations. None of the GPS equipment is transmitting data.

UNAVCO, a member of the Yellowstone Volcano Observatory consortium, is responsible for maintaining the deformation network in and around Yellowstone. In Yellowstone National Park alone this network includes 14 GPS stations and six borehole geophysics stations. All the data are free and open access.

The oldest clue of animal life, dating back at least 100 million years before the Cambrian period, when most major types of animals appear, has been found by University of California, Riverside (UCR) researchers.

The researchers have been tracking molecular signs of animal life, called biomarkers, as far back as 660–635 million years ago during the Neoproterozoic Era. They found a steroid compound produced only by sponges, which are among the earliest forms of animal life, in ancient rocks and oils from Oman, Siberia, and India.

The biomarker identified, a steroid compound named 26-methylstigmastane (26-mes), has a unique structure that is currently only known to be synthesized by certain species of modern sponges called demosponges.

A new treatment strategy could increase the success rate of stem cell transplants, according to University of Queensland researchers.

The approach removes the need for donor matching and the use of immunosuppressant drugs to prevent rejection, and could make stem cell treatment accessible to more patients.

UQ Diamantina Institute researcher Dr Jatin Patel said researchers found immunosuppressant drugs had a negative impact on the transplanted stem cells.

Whether they’ll ever be able to unearth it from a vast complex of at least seven dome-shaped burial mounds remains to be seen.

Should there be any ethical or legal boundaries to technologies that enhance humans? I pondered this last week as I read an online article about the recent trials of upper-body “exoskeletons” by production line staff at Volkswagen and at Chrysler-Fiat. These lightweight wearable frames greatly reduce the physical strain of repetitive overhead assembly work, and will be an important industrial enhancement as workforces age.

We tend to think of medical advancement in terms of better cures for diseases and recovery from injury. Enhancement however goes beyond therapy, and extends us in ways that some may argue are unnatural. Some human enhancements are of course also pre-emptive therapeutic interventions. Vaccination is both an enhancement of our immune system, and a therapeutic intervention. However, in cases where there is little preventative justification, what degree of enhancement is acceptable?

We drink coffee expecting our work performance to improve. We accept non-elective operations, breast implants, orthodontic improvements and other interventions which improve our perception of ourselves. We generally accept such enhancements with little question. However devices and drugs that improve athletic performance can lead us to question their legitimacy.
