Highly secret bacteria

Scientists from Tufts University called the method of encoding text with strains of luminous bacteria "steganography using printed microbial matrices." Unlike cryptography, which hides the meaning of a message, steganography hides the very fact of its existence (the simplest example is a letter with "invisible ink").

Retirement shortens life

Retirement is a factor of shortening life, – Professor P. Vorobyov is sure. So the later you retire, the higher the life expectancy, and not vice versa. We, gerontologists, have been calling for 15 years to raise the retirement age for everyone to 65.

The GMO Saga

GMOs are precisely under such vigilant and close control of scientists, which cannot be compared with any other product of human activity.

ESCs against blindness: clinical studies in Europe

Advanced Cell Technology has announced the imminent launch of Europe's first medical experiment for the treatment of juvenile retinal dystrophy using human embryonic stem cells.

Adult stem cells can be rejuvenated!

The aging process of adult stem cells responsible for the regeneration of worn or damaged tissues can be reversed. Perhaps this discovery will lead to the development of treatments for a number of age-related diseases.

Treat a heart attack only with healthy stem cells!

Successful experiments on the treatment of infarction with stem cells in mice were not confirmed in humans: mice were injected with bone marrow cells of healthy individuals, and people, in order to avoid immune conflict, their own, for unknown reasons, "spoiling" shortly after a heart attack.

Do you want to live long? Do autophagy, not sex!

The mutual stimulation existing between autophagy and the LIPL-4 fat-splitting enzyme increases the life of C.elegans roundworms by 25%.

The End of aging: Why does life start at 90?

If you are lucky and you live to a very old age, your body will stop aging. Can we learn to stop the hands of this clock earlier?

A virus trained to search for and destroy cancer cells

A few weeks after a single injection of the JX-594 virus culture to patients with metastatic cancer, half of the participants in the experiment had the tumor stopped growing, and one even decreased in size.

Take care of the vessels of the brain!

Many symptoms of aging, such as shaking hands, balance disorders, difficulty walking, etc., can be caused by blockage of the smallest vessels of the brain, which cannot be detected using existing methods.

There's no point in such a slender figure...

Envy the owners of a "genetic overdose", naturally thin, like a model dying of anorexia, is not worth it: every fourth of them receives microcephaly in a set of super-slimness.

Poison the tumor with oxygen!

A tiny oxygen generator injected into the tumor using a biopsy needle will increase the effectiveness of radio and chemotherapy for malignant tumors.

The blood of old people ages young brains, and young – rejuvenates senile

Do not rush to hide children from bloodsuckers: if the research is completed successfully, synthetic chemokines can be used for rejuvenation.

Senile bone fragility is not only osteoporosis

The reason for the increase in bone fragility as we age lies not only in the decrease in bone mass, leading to osteoporosis. Aging leads to deterioration of the mechanical properties of the cortical substance (outer layer) of the bone at different structural levels.

Legalize euthanasia?

Supporters of the unconditional legalization of euthanasia are about 49% of the French, another 45% consider such a measure possible if certain conditions are met. Moreover, representatives of older age groups support this measure more than young people.

Cathepsin S is a biomarker of death from senile diseases

High levels of cathepsin S in the blood of elderly people indicate an increased risk of death from cancer or cardiovascular diseases.

Immune System Rejuvenation: Inhibit inhibitors!

Suppression of one of the signaling mechanisms activated by an encounter with an infectious agent makes it possible to temporarily rejuvenate inactivated T-lymphocytes of the aging immune system.

Who should I be: a slender old man or a youngish fat man?

Researchers from Yale claim that free radicals make us overeat – one of the causes of aging. A disappointing alternative: be young and fat or aging fast, but with a great figure…

Poverty is not a vice, but it shortens telomeres

Over the past ten years, people from the low-income group have shortened telomeric sections of chromosomes on average by an order of magnitude more than their wealthier compatriots.
