While many research teams worldwide are trying to develop highly performing quantum computers, some are working on tools to control the flow of heat inside of them. Just like conventional computers, in fact, quantum computers can heat up significantly as they are operating, which can ultimately damage both the devices and their surroundings.
A huge lake in Bolivia has almost entirely disappeared. Lake Poopó used to be the country's second largest, after Lake Titicaca, and just a few decades ago in its wet season peak it would stretch almost 70km end to end and cover an area of 3,000 sq km – the size of a small country like Luxembourg. Today, the lake is largely a flat expanse of salty mud.

When an LNO catalyst with a nickel-rich surface carries out a water-splitting reaction, its surface atoms rearrange from a cubic to a hexagonal pattern and its efficiency doubles. Deliberately engineering the surface to take advantage of this phenomenon offers a way to design better catalysts.
A shapeshifting immune system protein called XCL1 evolved from a single-shape ancestor hundreds of millions of years ago. Now, researchers at the Medical College of Wisconsin (MCW) discovered the molecular basis for how this happened. In the process they uncovered principles that scientists can use to design purpose-built nanoscale transformers for use as biosensors, components of molecular machin
A Duke-led team of scientists has developed a bio-compatible surgical patch that releases non-opioid painkillers directly to the site of a wound for days and then dissolves away. The polymer patch provides a controlled release of a drug that blocks the enzyme COX-2 (cyclooxygenase-2,) which drives pain and inflammation. The study appears Jan. 10, 2021 in the Journal of Controlled Release .

Must-have for all parents. (Kelly Sikkema via Unsplash /) For the first 3 to 4 months of life the best way to sleep is to be wrapped up tight. Not only is this comfortable for your little one, but it suppresses their startle reflexes which encourages them to sleep longer and keeps them warm without the use of loose blankets, which can be dangerous. They also make great gifts for those of you with
For years, researchers have worked to repurpose excess atmospheric carbon dioxide into new chemicals, fuels and other products traditionally made from hydrocarbons harvested from fossil fuels. The recent push to mitigate the climactic effects of greenhouse gases in the atmosphere has chemists on their toes to find the most efficient means possible. A new study introduces an electrochemical reactio
The 'Third Pole' centered on the Tibetan Plateau is home to headwaters of over 10 major Asian rivers. These glacier-based water systems, also known as the Asian Water Towers, will have to struggle to quench the thirst of downstream communities despite more river runoff brought on by a warmer climate, according to a recent study published in Nature Climate Change.

COVID-19 patients who also suffer from high blood pressure are more likely to fall severely ill with the disease, which also leaves them at greater risk of death. Scientists have now found that the immune cells of patients with hypertension are already pre-activated, and that this pre-activation is greatly enhanced under COVID-19.
A new study has found that up to 20% of aggressive brain cancers are fueled by overactive mitochondria and new drugs in development may be able to starve the cancers.
The genetic material of plants, animals and humans is well protected in the nucleus of each cell and stores all the information that forms an organism. For example, information about the size or color of flowers, hair or fur is predefined here. In addition, cells contain small organelles that contain their own genetic material. These include chloroplasts in plants, which play a key role in photosy
Researchers were able to demonstrate how a specific bacterium inside the seeds of rice plants effectively and in an eco-friendly way inhibits destructive plant pathogens.
Mothers are not more likely to support gun control efforts, a new study shows. In fact, the researchers report that parenthood doesn't have a substantial effect on the gun control views of men or women. "To be clear, most women—including most moms—support more restrictive gun laws. But it's not because they're parents." "Everybody 'knows' that moms are more politically liberal on gun control issu
