Old-growth forests and managed forests with old-growth characteristics can provide relief from climate change for some bird species, research suggests.

The Cincinnati Art Museum turned to a scientist at the University of Cincinnati for help solving a mystery 1,300 years in the making. Together they examined whether decorative features on a Tang dynasty dancing horse were original to the sculpture or added at some later date.
We're all capable of slowing down the effects of a warming Earth, and it could be as simple as how we stock our pantries.
Physicists have demonstrated a new magnetized state in a monolayer of tungsten ditelluride. This material of one-atom thickness has an insulating interior but a conducting edge, which has important implications for controlling electron flow in nanodevices.
A study reveals that the incidence of early onset cancers (those diagnosed before age 50), including cancers of the breast, colon, esophagus, kidney, liver, and pancreas among others, has dramatically increased around the world, with this drastic rise beginning around 1990. In an effort to understand why many more younger individuals are being diagnosed with cancer, scientists conducted extensive...
Abrahamic texts treat slithering as a special indignity visited on the wicked serpent, but evolution may draw a more continuous line through the motion of swimming microbes, wriggling worms, skittering spiders and walking horses. A new study found that all of these kinds of motion are well represented by a single mathematical model.
Researchers have made a technological breakthrough and constructed a perovskite solar cell with the dual benefits of being both highly efficient and highly stable.
The COVID-19 pandemic affected American households in countless ways, but according to researchers, some of the most tangible shifts are taking place in the food system.
Noninvasive ventilation is possible in infants at limits of viability. But unlike in slightly older preterm infants, noninvasive ventilation did not show an advantage in infants of 22 weeks-0 days to 23 weeks-6 days gestational age, according to a new study.
Engineering researchers have created new high-power electronic devices that are more energy efficient than previous technologies. The devices are made possible by a unique technique for 'doping' gallium nitride (GaN) in a controlled way.
A new study has found that older people with insomnia are at greater risk of developing memory decline and long-term cognitive impairment such as dementia.
A team of scientists has uncovered intriguing new insights into the diet of people living in Neolithic Britain and found evidence that cereals, including wheat, were cooked in pots.
Some species of tardigrades, or water bears as the tiny aquatic creatures are also known, can survive in different environments often hostile or even fatal to most forms of life. For the first time, researchers describe a new mechanism that explains how some tardigrades can endure extreme dehydration without dying. They explored proteins that form a gel during cellular dehydration. This gel...
A research team has developed a high-resolution holographic endoscope system thinner than an injection needle for microscopic imaging inside a curved passage.
The survival of an ant colony depends on its members being able to distinguish their own nestmates from ants of a foreign -- and possibly hostile -- colony. This so-called nestmate recognition is based on scents emitted by a very thin layer of wax that coat the body of every ant. At the same time, this wax layer protects the ant body against water loss. Scientists have now found that these two...
Jupiter-sized planets can be stolen or captured by massive stars in the densely populated stellar nurseries where most stars are born, a new study has found.
Healthy young people with just a mild COVID infection can sometimes suffer temporary post-infection consequences such as tiredness, loss of smell and taste or reduced fertility. These symptoms usually improve with time. But a new conducted with Swiss Armed Forces personnel shows that young people post Covid are likely to have increased cholesterol, a high BMI, and a reduced level of physical...
Due to the uncertainty of the timing of vaccine approval at the beginning of the COVID-19 pandemic, policymakers struggled to find the best mitigation measures. In a new study, researchers analyzed how the expectation of a vaccine influences optimal lockdown measures.
After a 60-minute walk in nature, activity in brain regions involved in stress processing decreases.
A team of physicists and chemists presents an organic thin-film sensor that describes a completely new way of identifying the wavelength of light and achieves a spectral resolution below one nanometer. As integrated components, the thin-film sensors could eliminate the need for external spectrometers in the future. A patent application has already been filed for the novel technology.
Physicists have succeeded in coupling different types of electron-hole pairs (excitons) in the van der Waals material molybdenum disulfide. This successful coupling allows them to utilize and control the different properties of the two types of electron-hole pairs -- and could pave the way for the production of a novel source of individual particles of light (photons).
Electron orbitals show where and how electrons move around atomic nuclei and molecules. In modern chemistry and physics, they have proven to be a useful model for quantum mechanical description and prediction of chemical reactions. Only if the orbitals match in space and energy can they be combined -- this is what happens when two substances react with each other chemically. In addition, there is...
Honeybees rely heavily on flower patterns -- not just colors -- when searching for food, new research shows.
A woman's mercury level during pregnancy is unlikely to have an adverse effect on the development of the child provided that the mother eats fish, according to a new study.
The Gunflint Formation, which straddles Lake Superior's northwestern shore, contains a treasure trove of geological clues about the evolution of life. After a recent geological reassessment of this area, a research team has unearthed new types of microfossils dating 1.9 billion years. The landmark discovery will help scientists pinpoint the timing and factors that ushered in the evolution of...
