Biometrics is defined as the measurement of life signs. One of the main aims of current security research is to acquire biometric data of sufficient detail and reliability for verification or identification of individuals.

A newly developed electric-field sensing technology with unprecedented sensitivity and noise immunity can passively acquire physiological signals in an electrically noisy environment.

In this paper, we characterize and discriminate between normal and cancer cells from three different tissue types, liver, lung, and breast, using capacitance–voltage-based extracted set of parameters. Cells from each type of cancer cell line were suspended in a liquid media either individually or as mixtures with their normal counterparts. Empirically, normal cells were observed to exhibit higher dielectric constants when compared to cancer cells from the same tissue. Moreover, adding cancer cells to normal cells was observed to increase the capacitance of normal cells, and the extent of this increase varied with the type of tissue tested with the lung cells causing the greatest change. This shows that the cancer cells of different cell origin possess their own signature electrical parameters, especially when compared with their normal counterparts, and that cancer cell seems to affect normal cells in a different manner, depending upon the tissue type. It was also noticed that the cells (both cancer and normal) exhibited a higher dielectric value as per the following order (from least to most): breast, lung, and liver. The changes in electrical parameters from normal to cancer state were explained not only by the modification of its physiological and biochemical properties but also by the morphological changes. This approach paves the way for exploring unique electrical signatures of normal and their corresponding cancer cells to enable their detection and discrimination.

Though it may not have the sting of death and taxes, presbyopia is another of life’s guarantees. This vision defect plagues most of us starting about age 45, as the lenses in our eyes lose the elasticity needed to focus on nearby objects. For some people reading glasses suffice to overcome the difficulty, but for many people the only fix, short of surgery, is to wear progressive lenses.

“More than a billion people have presbyopia and we’ve created a pair of autofocal lenses that might one day correct their vision far more effectively than traditional glasses,” said Stanford electrical engineer Gordon Wetzstein. For now, the prototype looks like virtual reality goggles but the team hopes to streamline later versions.

Wetzstein’s prototype glasses—dubbed autofocals—are intended to solve the main problem with today’s progressive lenses: These traditional glasses require the wearer to align their head to focus properly. Imagine driving a car and looking in a side mirror to change lanes. With progressive lenses, there’s little or no peripheral focus. The driver must switch from looking at the road ahead through the top of the glasses, then turn almost 90 degrees to see the nearby mirror through the lower part of the lens.

Researchers at Germany’s Max Planck Institute for Intelligent Systems have developed a new type of self-assembling mobile micromachine that can be programmed to assemble into different formations — ranging from a tiny car to a miniature rocket. Here’s what’s next for the project.

Sirtuins can be activated by a lack of amino acids or of sugar, or through an increase in NAD. — David Sinclair If you have not heard of #davidsinclair then it is time you have. he is at the forefront of anti aging research and one of my heroes.

Can a single molecule extend lifespan?

Devices tucked inside your ears will make technology more personal than ever before.

Researchers may be closer to improving the lives of people with coronary artery disease and children born with pediatric congenital cardiovascular defects through the development of a new vascular graft created by Johns Hopkins engineers that takes less than one week to make and has regenerative properties.

Coronary artery disease, or CAD, is the leading cause of death worldwide and people with the disease often require surgery to repair damaged cardiovascular tissue. Bypass surgery, another common intervention, requires removing the damaged tissue and replacing it with blood vessels from another part of the body, such as the saphenous vein, which runs the length of the leg and is the longest vein in the body. This method puts substantial stress on the body and has other risk factors: it requires patients to have multiple surgical sites, and those in need of the surgery because of plaque build-up may also have plaque accumulation in the grafted vein, causing further complications.

Congenital cardiovascular defects, or CCD, occurs in 1% of live births worldwide, and children born with the condition often undergo repeated surgical reconstruction as they grow. But repeated surgeries reduce the amount of usable vascular tissue for reconstruction and synthetic grafts do not grow as the child grows.

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.
