Tasmanian devil research provides new insights for treating human cancers in future

A rare, transmissible tumor has brought the iconic Tasmanian devil to the brink of extinction, but new research by scientists at Washington State University and the Fred Hutchinson Cancer Research Center in Seattle indicates hope for the animals' survival and possibly new treatment for human cancers.

Study reveals changes in transmissibility of SARS-CoV-2 due to D614G spike mutation

A recent research endeavor from the UK, currently available on the medRxiv preprint server, indicates that spike 614G variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) increases in frequency relative to 614D variant in a selective advantage manner – but without higher coronavirus disease (COVID-19) mortality rates.

Existing drug used to treat alcoholism is potentially effective against COVID-19

A team of chemists from HSE University and the Zelinsky Institute of Organic Chemistry used molecular modelling to find out that two medications that have been known for a long time can be used to fight SARS-CoV-2.

Study provides new insights into how ovarian cancer grows and evolves

In a paper published in the journal Cancer Research, professor Levi Waldron, post-doctoral fellow Ludwig Geistlinger, and colleagues at the Institute for Implementation Science in Population Health at the CUNY Graduate School of Public Health and Health Policy) provide new insights into how ovarian cancer grows and evolves within a person.

Study could help explain how new species of flies evolve over time

The size of a fly's eyes and nose reflect both its behaviour during mating and its habitat preferences, according to a new study published today in eLife.

De novo protein decoys that block SARS-CoV-2

Now, a new study published on the preprint server bioRxiv in August 2020 shows that computational design technology can be efficiently harnessed towards this end, producing new molecules to inhibit viral entry and replication.

Study shows how amyloid fibrils in Alzheimer's dissociate with infrared laser irradiation

The agglomeration of proteins into structures called amyloid plaques is a common feature of many neurodegenerative diseases, including Alzheimer's.

Regulatory mechanisms involved in brain development are same for insects and mammals

With these new findings scientists can potentially better understand the subtle changes that can occur in genes and brain circuits that can lead to mental health disorders such as anxiety and autism spectrum disorders.

Researchers identify unique fungi species during COVID-19 pandemic

A major comprehensive study on Herpomycetales and Laboulbeniales, two orders of unique ectoparasitic fungi associated with insects and other arthropods (class Laboulbeniomycetes) in Belgium and the Netherlands was published in the open-access, peer-reviewed scholarly journal MycoKeys.

High-speed atomic force microscopy reveals diverse amyloid structures and dynamics

In the human body, proteins sometimes occur in fibrillar aggregates called amyloids. Although certain amyloids are known to have a biological function, amyloid formation is often associated with pathologies, including Alzheimer's and Parkinson's diseases.

Photonics-based device could help COVID-19 patients with adequate treatments

Few could have foreseen the considerable impact that SARS-CoV-2 has had so far and is still having worldwide. Numbers continue to escalate and the complexity of the COVID-19 symptoms have hindered all efforts to optimize its treatment.

Air travel helped spread novel coronavirus in Brazil

Domestic and international air travel helped spread the novel coronavirus in Brazil, a study has found, as tourism bodies push for global travel to resume amid infection resurgences in some countries.

Human cerebellum has almost 80% of the cerebral cortex’s surface area

When we say someone has a quick mind, it may be in part thanks to our expanded cerebellum that distinguishes human brains from those of macaque monkeys, for example.

Animal assisted therapy can improve outcomes in children with autism spectrum disorders

Doctoral candidate of the Education Programme of Castellón's Jaume I University (UJI), Juan Vives Vilarroig, has highlighted in his thesis the importance of working on basic aspects such as balance and postural control to improve sensory integration in children with autism spectrum disorders, using horses as the main elements of this intervention.

Study offers new possibilities for developing anti-aging drugs

KAIST researchers have been able to dial up and down creatures' lifespans by altering the activity of proteins found in roundworm cells that tell them to convert sugar into energy when their cellular energy is running low.

Multiple, intertwined cell death systems to prevent the spread of 'intracellular' bacteria

Melbourne researchers have revealed the multiple, intertwined cell death systems that prevent the spread of the 'intracellular' bacterium Salmonella, an important cause of typhoid fever which kills more than 100,000 people annually.

Relatives of SARS-CoV-2 may pose a health threat for years to come

Coronaviruses are zoonotic viruses that jump from animals to humans and cause infection. There are many types of common human coronaviruses, which usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. Most people get infected with one or more of coronavirus types 229E, NL63, OC43, and HKU1 at some point in their lives.

Remnants of bird ovaries can be preserved in the fossil record, confirms study

A research team led by Dr. Alida Bailleul from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences has put one controversy to rest: whether or not remnants of bird ovaries can be preserved in the fossil record.

UMass Amherst biologists identify environmental sensing mechanism in cells

Evolutionary and developmental biologist Craig Albertson and colleagues at the University of Massachusetts Amherst report that they have identified a molecular mechanism that allows an organism to change the way it looks depending on the environment it is exposed to, a process known as phenotypic plasticity.

Evolutionary origins of SARS-CoV-2 identified

By reconstructing the evolutionary history of SARS-CoV-2, the virus that is responsible for the COVID-19 pandemic, an international research team of Chinese, European and U.S. scientists has discovered that the lineage that gave rise to the virus has been circulating in bats for decades and likely includes other viruses with the ability to infect humans.
