Human dental pulp stem cells: Applications in future regenerative medicine

Posted by in categories: biotech/medical, life extension, neuroscience

Stem cells are pluripotent cells, having a property of differentiating into various types of cells of human body. Several studies have developed mesenchymal stem cells (MSCs) from various human tissues, peripheral blood and body fluids. These cells are then characterized by cellular and molecular markers to understand their specific phenotypes. Dental pulp stem cells (DPSCs) are having a MSCs phenotype and they are differentiated into neuron, cardiomyocytes, chondrocytes, osteoblasts, liver cells and β cells of islet of pancreas. Thus, DPSCs have shown great potentiality to use in regenerative medicine for treatment of various human diseases including dental related problems. These cells can also be developed into induced pluripotent stem cells by incorporation of pluripotency markers and use for regenerative therapies of various diseases. The DPSCs are derived from various dental tissues such as human exfoliated deciduous teeth, apical papilla, periodontal ligament and dental follicle tissue. This review will overview the information about isolation, cellular and molecular characterization and differentiation of DPSCs into various types of human cells and thus these cells have important applications in regenerative therapies for various diseases. This review will be most useful for postgraduate dental students as well as scientists working in the field of oral pathology and oral medicine.

Tesla Roadster Battery Range To Eclipse 1000 Kilometer Mark: Elon Musk

Posted by in categories: Elon Musk, space travel, sustainability

The previous Tesla Roadster Battery range of 1000 km was a conservative estimate. It is the range which users will get if they drive like a maniac. Who can blame them, when the car does 0–100 km/h in under 2 seconds.

Furthermore, Tesla fans also remember that a founders edition with cold gas thrusters is also coming in very limited numbers for hardcore electric car enthusiasts.

It is 2019 and the numbers provided by electric cars have already begun to eclipse the likes of Lamborghini Aventador and Bugatti Veyron. Lamborghini Aventador currently gives 10 MPG (Miles per gallon) or 4.25 km/l in the city, while the Bugatti Veyron delivers an embarrassingly low 7 MPG or 2.97 km/l.

Toyota unveils latest heavy-duty electric fuel-cell truck to haul cargo around LA

Posted by in categories: energy, transportation

The latest version of Toyota’s zero-emissions fuel-cell powered tractor truck was unveiled today in Los Angeles. Developed as part of a joint project with the Kenworth Truck Company, the Port of Los Angeles, and the California Air Resources Board (CARB), the Fuel Cell Electric heavy-duty Truck (FCET) that runs on hydrogen and produces only water as waste is intended to meet or exceed the performance of a conventional diesel truck.

Heavy metals like arsenic and lead found in 45 packaged fruit juices, report finds

Posted by in categories: biotech/medical, health

A new report out Wednesday says some popular fruit juices may contain heavy metal contaminants like lead, arsenic, and cadmium. Consumer Reports tested 45 packaged fruit juices and found measurable levels of heavy metal in every product. Long-term exposure to these metals could cause serious health risks, including kidney disease and certain types of cancer. Anna Werner reports.

Scientists seek genetic answer to predatory nature of invasive lionfish

Posted by in category: genetics

The lionfish is an invasive species that is currently wreaking havoc in the warm waters of the Bahamas, the Caribbean, and the US southwestern Atlantic and Gulf of Mexico coasts. But where did they come from and what makes this normally docile hunter suddenly turn vicious in its new home? To answer these questions, North Carolina State University initiated a study of lionfish genetics to learn more about their origins and how to control them.

Dark Matter Scientists Observe the Rarest Event in History

Posted by in category: cosmology

Researchers at the XENON dark matter observatory have spotted something incredibly rare. Unfortunately, it’s not dark matter, but it is the next best thing. The detectors at the observatory have spotted the decay of xenon-124, the rarest event ever recorded in human history.

The XENON experiment is designed to detect dark matter, which is not an easy task. The reason that dark matter is so mysterious is that it pretty much never does anything, which makes it hard to spot. Dark matter doesn’t give off light, or have any sort of magnetic field, and it almost never interacts with normal matter in any way.

Autonomous robotic device helps heal live pigs’ hearts

Posted by in categories: biotech/medical, robotics/AI

For some time now, we’ve seen robotic surgical devices that can be remotely guided within the human body. And while they do make surgery more precise and less invasive, they still have to be continuously operated by a surgeon. Recently, however, a robotic catheter successfully navigated beating pig hearts on its own.
