Synthetic protocells can be made to move toward and away from chemical signals, an important step for the development of new drug-delivery systems that could target specific locations in the body.

(Institut Pasteur) Researchers have demonstrated that an imbalance in the gut microbiota, also known as 'dysbiosis', promotes the onset of colorectal cancer. The teams demonstrated that transplanting fecal flora from pat...

(Credit: Tomsickova Tatyana/Shutterstock) A new study takes a look at the rates of extramarital childbirth in Europe over the past 500 years. This includes children born as the result of adultery -- and, spoiler, it's mu...

For older adults, Fitbits and other activity trackers may be popular gifts, but they may not be used for very long. While counterintuitive, engaging in competition with family and friends decreases the odds of long-term ...

Intermittent exposure to high levels of alcohol in adolescent animals leads to increased levels of microRNA-137 in the brains of adults. Blocking microRNA-137 helps to reverse or the lasting effects of youth drinking, su...

A servo motor, used for position feedback of angular rotation, applies pulse width modulation (PWM) signals for precise control over motion. Industrial design engineers can change the rotation angle and direction of the ...

The best commercial lithium-ion batteries today deliver energy densities of around 250 Wh/kg. But battery chemistry oriented around lithium-sulfur could deliver double that figure. This potential improvement has brought ...

New research finds that if Africa chooses a future powered by fossil fuels, nearly 50,000 people could die prematurely each year from fossil fuel emissions by 2030, mostly in South Africa, Nigeria and Malawi.

Children born to women on HIV therapy containing the drug efavirenz were 2 to 2.5 times more likely to have microcephaly, or small head size, compared to children born to women on regimens of other antiretroviral drugs, ...

New research shows that a particular subclass of low-density lipoproteins (LDL) is a much better predictor of potential heart attacks than the mere presence of LDL.

Communities in the United States that experienced the most economic distress in the wake of the Great Recession saw a significant increase in death rates from heart disease and strokes among middle-aged people. While the...

PRO DESIGN announced the launch of its innovative high-capacity proFPGA quad Stratix 10 GX 10M system. It is the next generation of its successful, modular, scalable and most compact high-performance FPGA Prototyping sol...

Researchers have demonstrated that an imbalance in the gut microbiota, also known as 'dysbiosis', promotes the onset of colorectal cancer. The teams demonstrated that transplanting fecal flora from patients with colon ca...

Heilind Electronics is now stocking the manufacturer's VarioBoot RJ45 overmolded cable assemblies. The patch cords introduce the flexibility of controlling the angle and orientation of the RJ45 connectors, creating an id...

With typical temperature-reading accuracy of 0.25°C and low operating and standby current, the STMicroelectronics STTS22H enhances temperature and heat-flow monitoring in asset trackers, shipping-container loggers, HVAC...

Twice-yearly injections of an experimental cholesterol-lowering drug, inclisiran, were effective at reducing low-density lipoprotein (LDL) cholesterol, often called bad cholesterol, in patients already taking the maximum...

Researchers found that a single, low-dose ketamine infusion was relatively free of side effects for patients with treatment-resistant depression. Widespread off-label use of intravenous subanesthetic-dose ketamine has ra...

Silicon carbide (SiC) is en route to mainstream for applications like photovoltaic and uninterruptable power supplies. Infineon Technologies now targets the next group of applications for this wide bandgap technology: Th...

We live in a world of solid-state active devices that have made most vacuum tubes obsolete, but a few types remain as they are still indispensable. Part 1 of this article explained the basics of the photomultiplier tube....

New research shows that ramping up one of the body's waste disposal system, called autophagy, helps heal the blood vessels of diabetics.

Progeria is a very rare disease that affects about one in 18 million children and results in premature aging and death in adolescence from complications of cardiovascular disease. In a study on mice and human cells, rese...

Maybe we can't live with them, but we can't live without them, at least not yet: the photomultiplier tube and the traveling wave tube are two vacuum electron-tube devices that are still viable and needed in our solid-sta...
