Graying Hair Is Reversible?

History is littered with anecdotal evidence of the relationship between stress and graying hair, from Marie Antionette’s overnight transformation following her capture, to US presidents taking on more salt than pepper during their tenure. A new study has produced first-of-a-kind scientific evidence of this connection, identifying proteins in human hairs that seem to drive this process, while also demonstrating how […]

Graphene Camera Images The Electric  Field Of The Heart

Scientists at the University of California, Berkeley, (UC Berkeley) have demonstrated yet another use for the ever-versatile wonder material graphene, using it as the basis for an advanced sensor that can image electrical signals from living cells and tissue in real time. The team’s “graphene camera” was used to record electrical activity of a beating heart in action, and could […]

Promising Vaccine For Malaria?

The pursuit of a vaccine for malaria has always been an important one, with more than 400,000 people dying from the disease every year. But with the parasite behind it becoming resistant to drugs and the mosquitoes that spread it becoming more resistant to pesticides, there is a need for new, advanced weapons in the fight. A new technology could […]

Studies Shows Caloric Restrictions Beats Fasting

A trial led by researchers from the University of Bath is questioning the value of popular fasting diets, finding a simple calorie-controlled diet is more effective at reducing weight. The trial also found fasting can lead to greater losses of muscle mass. Intermittent fasting is a popular dietary phenomenon that can take a wide variety of forms, from time-restricted feeding […]

Getting Serious Covid Side Effects After Vaccination Is Very Rare

A promising new report from the US Centers for Disease Control and Prevention (CDC) has found less than 1,000 cases of COVID-19 needing hospitalization out of more than 100 million fully vaccinated people. The CDC admits it is probably undercounting positive COVID-19 cases, however, the report offers a powerful reminder of the real-world effectiveness of vaccines. The CDC report chronicles […]

Assistive Tech For Seniors 

As a senior’s sense of balance deteriorates, their chances of experiencing a serious fall increase accordingly. Help may be on the way, however, in the form of a system that buzzes the user’s fingertip in order to keep them upright. One of the consequences of an impaired sense of balance is a tendency to sway when standing and walking. It […]

Sniffing Out Cancer From Blood Samples?

Researchers at the University of Pennsylvania have developed an electronic nose (or e-nose) that may be able to sniff out signs of cancer from blood plasma samples. In tests, the device was able to detect a range of cancer types with over 90 percent accuracy. Volatile organic compounds (VOCs) are chemicals that are responsible for odors, with different sources releasing […]

Tiny Harvester For Plant Cells

Imagine if in order to get apple juice, the whole tree had to be ground up, and then the juice had to be separated from everything else. Well, that’s kind of how things currently are with therapeutic plant extracts … but perhaps not for much longer, thanks to a tiny new harvester. Currently being developed at the Technical University of […]

Reverse 3D Printing Bone Scaffold 

For some time now, we’ve been hearing about scaffolding-like implants that encourage bone tissue or cartilage to grow back into areas where it’s missing. Now, scientists have developed a method for more quickly and easily 3D-printing such implants. First of all, just how does so-called “microscaffolding” work? Well, if a patient is missing a section of bone (due to accident […]

Enzyme-Based Treatment 

With their often high-sugar diets and lax brushing habits, many children are particularly susceptible to cavities. An experimental new treatment could help, however, using enzymes to weaken the plaque that forms on the teeth. As many readers will already know, cavities are caused by a bacterial biofilm – commonly known as plaque – that grows on the tooth surface. According […]
