Earth's forests are indispensable for both humans and wildlife: they absorb CO2, provide food for large parts of the world's population and are home to all sorts of animals.
However, forest conservation measures are lagging in many countries, says Laura Vang Rasmussen, an assistant professor at the University of Copenhagen's Department of Geosciences and Nature Management.
The supersharp radio "vision" of the National Science Foundation's Very Long Baseline Array (VLBA) has revealed previously unseen details in a jet of material ejected at three-quarters the speed of light from the core of a galaxy some 12.8 billion light-years from Earth. The galaxy, dubbed PSO J0309+27, is a blazar, with its jet pointed toward Earth, and is the brightest radio-emitting blazar yet seen at such a distance. It also is the second-brightest X-ray emitting blazar at such a distance.
Many animal species use social information - from conspecifics or other species - to inform their behavioral choices, for example where to look for food or build a nest. In a recent study, ornithologists have shown for the first time that the ability to use such information can depend on an individual's cognitive skills. In the collared flycatcher, females that mastered a learning task faster were more likely to copy the nest site choices of great and blue tits in the same area.

Current Management Strategies in Patients with Heart Failure and Atrial Fibrillation: A Review of the Literature (http://ow.ly/zw3m30rnFaC) by Alex M. Parker, Juan R. Vilaro, Mustafa M. Ahmed and Juan M. Aranda
HOUSTON - (Dec. 22, 2020) - Bigger is not always better, but here's something that starts small and gets better as it gets bigger.
Just light it up and see.
A team led by Rice University chemists Christy Landes and Stephan Link, both associated with the Smalley-Curl Institute, have made hybrid particles that combine the unbeatable light-harvesting properties of plasmonic nanoparticles with the flexibility of catalytic polymer coatings. Their work could help power long-pursued plasmonic applications in electronics, imaging, sensing and medicine.

In what has the potential to significantly change how Corona patients are being treated and the severity of the disease, research spearheaded at Jerusalem's Hebrew University gathered early clinical evidence demonstrating the efficacy of an existing drug in treating COVID-19.
Washington DC, December 22, 2020 - A study in the Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP), published by Elsevier, reports that in a group of first-year university students COVID-19 mitigation protocols, including remote learning and stay-at-home orders had a modest, but persistent, impact on mood and wellnes
The Earth's soils contain more than three times the amount of carbon than is found in the atmosphere, but the processes that bind carbon in the soil are still not well understood.
Improving such understanding may help researchers develop strategies for sequestering more carbon in soil, thereby keeping it out of the atmosphere where it combines with oxygen and acts as a greenhouse gas.
A new study describes a breakthrough method for imaging the physical and chemical interactions that sequester carbon in soil at near atomic scales, with some surprising results.
Australian researchers have revealed - for the first time - that people who have been infected with the COVID-19 virus have immune memory to protect against reinfection for at least eight months.
The research is the strongest evidence for the likelihood that vaccines against the virus, SARS-CoV-2, will work for long periods. Previously, many studies have shown that the first wave of antibodies to coronavirus wane after the first few months, raising concerns that people may lose immunity quickly. This new work allays these concerns.
An analysis of the songs of most of the world's passerine birds reveals that the frequency at which birds sing mostly depends on body size, but is also influenced by sexual selection. The new study from researchers of the Max Planck Institute for Ornithology and colleagues suggests that habitat characteristics do not affect song frequency, thereby refuting a long-standing theory.
A study by University of Calgary researchers with the Hotchkiss Brain Institute examining sex and gender differences on sleep, empathy and mood during months of isolation due to COVID-19 has found that women are suffering more than men with poorer sleep and more anxiety, depression and trauma, while also feeling more empathetic than men.
ROCHESTER, Minn. -- Patients with COVID-19 who received care at Mayo Clinic, whether in the hospital or at home, had outcomes that compared favorably to those reported nationally and internationally. These results demonstrate the value of an integrated, team-based approach to patient care and monitoring, according to a retrospective study of all patients with COVID-19 treated at Mayo Clinic March 1-July 31.
A newly developed compound starves cancer cells by attacking their "power plants" - the so-called mitochondria. The new compound prevents the genetic information within mitochondria from being read. Researchers from the Max Planck Institute for Biology of Ageing in Cologne, the Karolinska Institute in Stockholm and the University of Gothenburg report in their study that this compound could be used as a potential anti-tumour drug in the future; not only in mice but also in human patients.
Bumble bees found in low-quality landscapes -- characterized by a relative lack of spring flowers and quality nesting habitat -- had higher levels of disease pathogens, as did bumble bees in areas with higher numbers of managed honey bee hives, according to research led by Penn State scientists.
