Winter conditions are changing more rapidly than any other season and researchers have found clear signs of a decline in frost days, snow covered days and other indicators of winter that could have lasting impacts on ecosystems, water supplies, the economy, tourism and human health.
Exposure to air pollution increases violent crime rates
- ScienceDaily
- 19/10/3 17:40
Breathing dirty air can make you sick. But according to new research, it can also make you more aggressive. That's the conclusion from a set of studies recently authored by Colorado State University researchers. The team found strong links between short-term exposure to air pollution and aggressive behavior, in the form of aggravated assaults and other violent crimes across the continental United...

The new generation of successful female bloggers and influencers on social media are changing the identity of the stereotypical 'ideal' housewife.
Bumble bee workers sleep less while caring for young
- ScienceDaily

All animals, including insects, need their sleep. Or do they? That's the question researchers are exploring in sleep studies of a surprising group of subjects: brood-tending bumble bee workers. Their studies show that worker bees tending pupae sleep much less than other bees do, even when caring for offspring that aren't their own.
Heart failure and the obesity paradox

Pesticides likely caused 'Havana syndrome' that affected Cuba-based diplomats
- ScienceDaily
- 19/10/3 17:17
The study details the nature of the injury, specifies the brain regions involved, including the blood-brain barrier and suggests a possible cause in the form of 'cholinesterase inhibitors,' with 'organophosphorus insecticides' being a likely source. Cholinesterase (ChE) is one of the key enzymes required for the proper functioning of the nervous systems of humans, invertebrates and insects.
New method to purify cell types to high purity
- ScienceDaily
- 19/10/3 17:17
Current biology research relies on the ability to purify cell types using antibodies or transgenic constructs. However, antibody availability is often limited, and genetic manipulation is labor intensive or sometimes impossible. To date, no universal method exists to enrich for cell types without a priori knowledge of cell type markers. Here, we propose GateID, a computational method that combines...
Parkinson's disease is also present in the blood

The behavior of immune cells in the blood is so different in patients with Parkinson's disease that it advocate for a new type of supplementary medicine, which can regulate the immune system and thus inhibit the deterioration of the brain.
Combustion behavior of aromatics may provide keys to enhancing heavy oil extraction
The problem of petroleum depletion becomes more and pertinent every day. As deficits arise, non-traditional and heavy oils, including bitumen and shales, emerge as the focus of extensive research. Globally, they account for about 60 to 70 percent of explored reserves. For Russia, it's also over 60 percent.

Fossilised partial skeleton of new flying reptile species found in Queensland
Pterosaur had four-metre wingspan, lived about 90m years ago and was capable of crossing continentsIn the heart of Queensland, palaeontologists have found the fossilised partial skeleton of a new pterosaur species capable of flying across continents.The pterosaur, with a four-metre wingspan, may have lived about 90m years ago.

UK particle accelerator to reveal secrets of 2,000-year-old papyrus
A leading science facility in the English countryside is helping in a bid to decipher Roman-era scrolls carbonised in the deadly eruption of Mount Vesuvius nearly 2,000 years ago. Researchers led by antiquities decoder Professor Brent Seales have turned to Diamond, Britain's national synchrotron in Didcot, Oxfordshire, to examine the papyri, which are described as "fragile like butterfly wings"....
New Australian pterosaur may have survived the longest
The discovery of a previously unknown species of pterosaur, which may have persisted as late as the Turonian period (90-93 million years ago), is reported in Scientific Reports this week. The fossil, which includes parts of the skull and five vertebrae, is the most complete pterosaur specimen ever found in Australia. The findings suggest it may be a late-surviving member of the Anhanguera genus of...
Engineered viruses could fight drug resistance
In the battle against antibiotic resistance, many scientists have been trying to deploy naturally occurring viruses called bacteriophages that can infect and kill bacteria.
Scientists discover a new mechanism for the transfer of maternal genetic material
Researchers at the Centro Nacional de Investigadores Cardiovasculares (CNIC) have established the dynamics of the transfer of mitochondrial DNA from mothers to their offspring. The study is published today in Cell Metabolism.
New method to purify cell types to high purity
Researchers from the group of Alexander van Oudenaarden at the Hubrecht Institute (KNAW) have developed GateID, a new method that can purify a cell type of interest from a tissue without the use of antibodies or a genetic reporter. GateID allows researchers to isolate a variety of cell types, such as stem cells, in order to study them in more detail. The researchers have published their results in...
Cause of rare but deadly neurological disease identified
A deadly neurological disease that primarily affects infant boys is caused by increased sensitivity to iron in the brain, according to a new study by researchers at the Stanford University School of Medicine, the University of California-San Francisco and the University of Cambridge.
Getting an 'eel' for the water: The physics of undulatory human swimming

Genomes of parasitic mites harming the world's bees sequenced
- ScienceDaily
- 19/10/3 16:35
Researchers sequenced the genomes of the two Varroa mite species that parasitize the honey bee. They found that each species of mite used its own distinct strategy to survive in its bee host, potentially overwhelming the bees' defenses. In addition to pointing to how scientists might vanquish these deadly intruders, the findings also shed light on how parasites and hosts evolve in response to one...
