New technology manipulates cells for disease research

A new method for altering the path and direction of cells has been developed by Northwestern University. The aim is to develop stem cell therapies for spinal cord injuries, stroke, and Parkinson’s disease.

Essential Science: Methylene Blue as an anti-aging treatment

Aging is inevitable for living organisms and part of the course of life. With modern medicine life expectancy can be extended and there are various ‘tricks’ to give the appearance of not aging. But is true slowing down of aging possible?

Essential Science: Battling infections with bioelectricity

Is the answer to fighting pathogens connected with bioelectricity? Promising new research suggest this is possible by using drugs to changing electrical charge of cells. Studies have been performed in frogs.

Optical tweezers designed to control cell behavior

A pair of optical tweezers has been developed, designed to control the behavior of cells for scientific study. Using the technology, cells can be microscopically altered in relation to position, orientation, and shape.

Viewing brain images by new adaptive-optics technology

Scientists from Purdue University have developed a new adaptive-optics technology designed for brain research. The method, described as “multi-pupil adaptive optics”, helps with research into brain function.

Smartphone batteries inspired by intestines

An odd mix – human biology and batteries designed to power smartphones – but it seems to work. A new type of lithium-sulfur battery has been designed along the lines of the structure of the cells in the gut.

New model to improve security of cloud computing

Adding a cell structure to cloud-based computing provides a system that is resilient to external compromise and one that severely limits the ability of an attacker to further exploit the organization beyond the cell.

Scientists think it's possible to reverse the aging process

The fountain of youth may be a myth but a gene called Nanog might lead to the same effect. A new research breakthrough could bring with it treatments for conditions like atherosclerosis, osteoporosis and Alzheimer’s.

Are pomegranates the next super-food?

Pomegranates could be the next super-food, at least because of its anti-aging properties. New research has shown how a chemical in the fruit, when processed by gut bacteria, helps protect muscle cells.

Researchers try to detect Alzheimer’s disease early

Scientists have developed a method for the earlier detection of Alzheimer’s disease. The method may be able to detect the neurodegenerative condition up to two decades earlier than current assessments.

Cancer battling nanoparticle method devised

A means of combating aggressive breast cancer with a drug based on nanotechnology has been developed. In animal trials, metastatic cancer was successfully treated, paving the way for human trials.

Stress wakes up the sleeping herpes virus

Helsinki - Once someone has contracted herpes the virus can emerge again at any time. The re-emergence is linked with periods of stress. Scientists have been looking into how this happens.

Do our bodies really have more microbes than human cells?

Pick up a text book on microbiology or human physiology. Chances are you’ll stumble across a reference to the number of microorganisms in the human body exceeding the number of cells ten-fold. But is this correct?

Shift work associated with more driving accidents

Birmingham - There are several ill-health effects associated with shift work. The latest in the growing body of medical science about the dangers of prolonged night work concerns driving safety.

Trial launched to investigate aspirin and cancer

A major study has begun to examine whether taking aspirin each day can stop some of the most common types of cancers from recurring.

Is it possible for engineered cells to heal Parkinson’s damage?

Parkinson’s disease is a type of neurodegenerative disease. As a possible treatment, researchers have engineered smarter immune cells to deliver a healing protein to the brain.

Scientists switch off cancer cells and return them to normal

A team of scientists at the US Mayo Clinic in Florida have succeeded in "switching off" cancer cells and making returning them to normal again.

Holding cells in limbo may combat cancer

A new study has found that delaying cellular activity can help keep cancer in control and may also slowdown the process of aging. This has been found through some molecular biological investigations.

Biological lock-and-key for GMO safety

Researchers have developed a way to allay one concern with GMOs entering the environment. This is based on a molecular lock-and-key, to inactivate unwanted microbes.

Using yeasts to study human obesity

Researchers think that the study of yeasts can be particularly useful for gaining insights into human obesity. To explore this further, a biologist collaborated with a mathematician.

New Loki microbes bridge gap between known life forms

A newly discovered life form appears to bridge to gap between animal cells and bacterial cells. Called Lokiarchaeota, the microbe is proving perplexing to microbiologists.

Woolly mammoth rebirth much nearer; cells now alive in laboratory

A major advance has been made in efforts to bring the woolly mammoth back to life. For the first time in over 3,000 years, mammoth DNA is alive in a laboratory and the aim of cloning the ancient animal is now much closer to becoming a reality.

How we think we eat affects how we age, says new study

A new study suggests that focusing on aspects of the central nervous system related to ‘sensing’ the energy generated by nutrients could help to slowdown the aging process.

Diaper compound makes cells appear 'really big'

In order to improve the power of optical microscopy, researchers have managed to enlarge key biological features inside cells.

New technology for making living tissue

A new method for constructing large tissues from living components of three-dimensional micro-tissues has been developed. Researchers hope that the process can one day building entire organs.

Human cells found to have sensory capability

Copenhagen - A new study has found that cells possess finger-like projections that are used to sense the external environment. These projections can detect the chemical environment and they can "feel" the through ultrasensitive sensors.

Solving the cellular conundrum, seeing how cells grow

Cell division has been part and parcel of our understanding of science for over a century. However, what exactly causes cells to divide? This is still a conundrum for scientists.

Ferrets provide flu clues

It has been discovered that ferrets share a mutation that was once considered unique to humans. The mutation explains why ferrets have the same susceptibility as people to the influenza A virus.

Seeing into cells with super-res microscopy

Philadelphia - New super-resolution microscopy allows scientists to see the make-up of cells in more detail than ever before. This allows the observation of many biological structures not resolvable in conventional fluorescence microscopy.

Turning flesh into stone for cancer research

Washington - A new technique that can transmute living cells into permanent materials is one step towards researchers developing more potent anti-cancer medications.
