A message printed out by a water-jet printer on a manganese-complex-coated paper is invisible to the naked eye, but the message reveals itself under 254 nm UV light. The paper can be ready for another round of printing after erasing the message by heating it w
If we rationally model everything like a depreciating corporate asset, we dangerously discount basic logic and moral clarity. The famed Standford "marshmallow test" assesses our ability to delay gratification, but if we were to cast the same experiment in moral terms, would we make the same decisions? Our current global markets marshmallow test isn't going so well. None Do you believe human natur
By this point, scientists have a pretty good handle on what kinds of big animals exist. Researchers still turn up new species of rats and insects, but most animals bigger than your hand are old news. But by looking at 90-year-old crocodile skulls in museum collections and double-checking with live specimens at a zoological park in Florida, researchers have just discovered a new species of ten-foot
Earth's oceans are a powerful tool when it comes to mitigating climate change. a new report argues. (Credit: NASA) A future where climate change is taken seriously everywhere — where batteries trump fuel tanks and forests stay intact — is easy to picture. But for too long, ideas of a sustainable planet have focused on what we can do on land, and not planned for what the ocean could help accomplish
As the White House prepared to release a summary of President Donald Trump's July call with Ukrainian President Volodymyr Zelensky, administration sources told reporters there wouldn't be much there. They were wrong. The summary, released Wednesday morning , is a wild look into the president's mindset and approach to his job. It shows a commander-in-chief consumed by conspiracy theories, strong-a
Zambia, a country in southeast Africa, has approximately 1,200 lions, one of the largest lion populations on the continent. More than 40% of the U-shaped country is protected land, with over 120,000 square miles of national parks, sanctuaries and game management areas for lions to roam.
In the quest for a more youthful appearance, many people slather ointments on their skin or undergo injections of dermal fillers. But topical treatments often aren't very effective because they don't penetrate deep within the skin, whereas the results from injections typically last for only a few months and can be painful. Now, researchers reporting in ACS Nano have developed a needle-free 'exosom
Emissions of greenhouse gases have a warming effect on the climate, whereas small airborne particles in the atmosphere, aerosols, act as a cooling mechanism. That is the received wisdom in any case. However, new research from Lund University in Sweden can now show that the tiniest aerosols are increasing at the expense of the normal sized and slightly larger aerosols — and it is only the latter t

Scientists at TU Dresden and Ulm University have succeeded in synthesizing sheet-like 2D polymers by a bottom-up process for the first time. A novel synthetic reaction route was developed for this purpose. The 2D polymers consist of only a few single atomic layers and, due to their very special properties, are a promising material for use in electronic components and systems of a new generation.
Infections that are treatable in healthy people can often be fatal in immunocompromised individuals (people with a weak immune system), and hence, they require specialized treatment. Eushearilide is already known to be active against a wide range of pathogenic fungi and yeasts, but its antibacterial properties have not been explored. Now, scientists from the Tokyo University of Science have derive

More than 90% of patients with mental health or substance use disorders had
For most plants, carbon dioxide acts like a steroid: The more they can take in, the bigger they get. But in a new study published Sept. 25, 2019, scientists with the Smithsonian discovered something strange happening in marshes. Under higher levels of carbon dioxide, instead of producing bigger stems, marsh plants produced more stems that were noticeably smaller.

People are less motivated to take action if an outcome is uncertain, and this could be true for climate-related issues. The uncertainty in climate response to the increase in greenhouse gas concentration, which is often believed to be substantially large, makes it difficult to believe the benefit of reducing emissions or the effectiveness of making society more resilient to climate-related hazards

A couple of years ago, I started invoicing my husband for housework. It made sense to us: While our goal was to divide the work equally, I ended up doing much more because he worked in an office and I worked at home as a freelancer, using my breaks to cook, vacuum, and do laundry. We split all our bills down the middle, except for rent, which we each paid in proportion to our income. But if we fe

I've said many times in the past that the Earth is the best planet in the universe. No matter where we go, we'll never find a planet that's a better home to Earth life than Earth. Of course, that's because we, and all other Earth life evolved in this environment. Evolution adapted us to this planet, and it's unlikely we could ever find another planet this good for us.
Queensland Museum researchers have been part of a rescue mission to preserve a centuries-old Aboriginal tree carving, helping document it for future generations using technology known as photogrammetry.
One of the reasons that people in or near this business can write such gaudy press releases is that it has so many moving parts. That lets everyone claim that the part that they're addressing is Crucial. Think of a car: the wheels are indeed key to mobility, but so is the engine. As is the oil, the power source (be it gas tank or battery), and any number of other parts. Or you can use the human b

Log-periodic quantum magneto-oscillations are observed in the magneto- and Hall resistance of the topological material HfTe5 crystals. The results reveal the log-periodicity in both transport coefficients as a general quantum effect arising from the supercritical atomic collapse and the concomitant quasi-bound states featuring discrete scale invariance. This provides new insights towards further u
Sponges form an extensive animal phylum with over 7,500 species worldwide, which occur in a wide range of habitats in the ocean. A special feature of this animal phylum is their ability to filter seawater, through which these organisms obtain their food. In doing so, certain sponge species can move up to 24,000 litres through their body per day. The surrounding seawater contains a wide range of vi

A research team in Ehime University prepared a new type of synthetic polymer, which can be degraded into a combination of well-defined low molecular weight compounds under very mild acidic conditions. The new polymer, poly(β-keto enol ether), has great potential to be utilized as an environmentally friendly material in the near future.
The climate crisis threatens to dramatically alter people's relationships with the land on which they rely. Meanwhile, many climate solutions are themselves land-intensive: solar and wind energy, carbon dioxide sequestration, and finding places for people displaced by climate change to live and grow food. The result is an ever-increasing competition for land, as well as governance and justice chal
From raindrops rolling off the waxy surface of a waterlily leaf to the efficiency of desalination membranes, interactions between water molecules and water-repellent "hydrophobic" surfaces are all around us. The interplay becomes even more intriguing when a thin water layer becomes sandwiched between two hydrophobic surfaces, KAUST researchers have shown.
Many vector-borne diseases are transmitted by mosquitoes. Mosquitoes are cold-blooded insects, which means that environmental conditions, in particular temperatures, regulate their metabolism, development and activity. For instance, mosquitoes develop faster when it is warmer (provided temperatures aren't too extreme). Given current and projected warming, most of the micro-environments that mosqui

In the vast garden of the universe, the heaviest black holes grew from seeds. Nourished by the gas and dust they consumed, or by merging with other dense objects, these seeds grew in size and heft to form the centers of galaxies, such as our own Milky Way. But unlike in the realm of plants, the seeds of giant black holes must have been black holes, too. And no one has ever found these seeds—yet.

Artificial intelligence (AI) appears to detect diseases from medical imaging with similar levels of accuracy as health-care professionals, according to the first systematic review and meta-analysis, synthesizing the available evidence from the scientific literature.
Hydrogen occurs in nature as H2 molecules; however when deuterium isotopes—so called "heavy hydrogen"—are introduced, the result can be deuterium hydride (HD) or deuterium gas (D2). These compounds are useful starting materials in fine chemical production; however, the natural abundance of these gases is low and the techniques used for producing D2 are expensive and energy intensive. Researchers f
By comparing observations to large ensembles of climate model simulations, scientists can now better isolate when human-caused climate change was first identifiable in observations.
Every year, a "dead zone" the size of Massachusetts sprawls across the Gulf of Mexico. The Mississippi River, which travels through the nation's farm belt, sweeps excess fertilizer and dumps the chemicals into the Gulf, where they feed rampant algae, deplete oxygen, and kill marine life.
Atrophied brain lesion volume is the only marker from MRI scans that can accurately predict which patients with multiple sclerosis will progress to the most severe form of the disease, a new study shows. Secondary progressive MS, known as SPMS, typically appears 10 to 20 years after the initial onset and causes more physical and cognitive impairments. Of the 1,314 patients in the 5-year study, mo

A solar cell is being turned into a light source by running electric current through it. Such 'luminescence' testing is performed routinely in ESA's Solar Generator Laboratory, employed to detect cell defects—such as the cracks highlighted here.
A group of physicists in Utrecht, San Sebastián and Pennsylvania have created a new artificial molecule that is insulating inside but has electronic states localized in its corners. These states have zero energy, and for this reason, are resilient to defects in the molecule and might be used as qubits in quantum computers. The results are published in Nature Materials on 23 September.
It is not possible to achieve the sustainable development goals (SDG) if science does not contribute with cross-disciplinary knowledge and understanding of how systems are interconnected.

Ever since the earliest years of this century, Ukraine has been the contested frontier in a grand ideological struggle between the forces of democracy and kleptocracy. It was in Ukraine that Russia tested the misinformation tactics that it used in the American presidential election of 2016. And when Russia meddled in the U.S. campaign, one of its ultimate objectives was stunting American pressure
At the dawn of the United States, before the Constitution, and more than 240 years before a U.S. intelligence source filed a whistle-blower complaint against President Donald Trump, Americans clearly understood the damage that high-ranking government officials can do if they use their public authority for private gain. Esek Hopkins, a Rhode Island slave runner who became the commander in chief of
What is an impeachable offense? When the Constitution's Framers needed to set the scope for unacceptable misconduct in office, they relied on a one-word shorthand: Hastings . As the Federal Convention of 1787 debated language subjecting the president to impeachment "for treason and bribery," George Mason objected that the narrowness of those terms would excuse some of the worst criminals: "Treaso
