The gold vapor laser has been widely used in the treatment of cancer using photodynamic therapy.


Using Blue Light to See Through Fire in Optical Imaging Dr Matthew Hoehler AZoOptics talks to Dr Matthew Hoehler about his recent research, using blue light to see through fires and make previously impossible qualitative observations about material damage during a fire.

Scientists really never back down. A new dental replacement procedure is in the works, and it could be a whole lot better than getting regular dentures or standard implants.

Losing a tooth is a source of major pain, and it also comes with a lot of issues and long-term discomforts. Dentures are one way to replace a lost or bad tooth, but they come with a lot of burdens on their own.

It takes a while to get used to having teeth you were not born with, and some people’s gums and jaw bones are just not suitable to receive implants.

Age is a leading risk factor for a number of conditions such as heart disease, cancer, and Alzheimer’s disease among others, such conditions make a real need for development of anti-aging therapies urgent. Salk Institute researchers may have developed a new gene therapy to help decelerate the aging process, as published in the journal Nature Medicine.

CRISPR-Cas9 genome editing therapy has been shown by the Salk Institute team to suppress the accelerated aging observed in mice with Hutchinson-Gilford Progeria syndrome; and provided insight into the molecular pathways involved in accelerated aging, and how to reduce toxic proteins via gene therapy.

Having an early onset and fast progression progeria is a severe form of degenerative disorder caused by LMNA gene mutations; signs of accelerated aging include DNA damage, cardiac dysfunction, and dramatically shortened lifespan. LMNA genes produce lamin A and lamin C inside a cell, progeria shifts production of lamin A to progerin which is a toxic shortened form of lamin A that accumulates with age and becomes exacerbated with the condition.

Doctors in London have used sound waves to successfully operate deep inside the brain.

They treated a man from Cornwall who suffered from uncontrollable tremors in his right hand.

UMBC’s Hua Lu, professor of biological sciences, and colleagues have found new genetic links between a plant’s circadian rhythm (essentially, an internal clock) and its ability to fend off diseases and pests. The findings were 10 years in the making and published in Nature Communications this week. The results could eventually lead to plants that are more resistant to disease-causing pathogens and better treatment for human diseases.

“It’s quite cool,” Lu says, “because, in both and animals, people are beginning to study the crosstalk between the clock and the immunity system.”
