How touch dampens the brain’s response to painful stimuli
Rubbing an aching body part can bring some relief. Neuroscientists at MIT's McGovern Institute are looking to find out why. When we press our temples to soothe an aching head or rub an elbow after an unexpected blow, it often brings some relief. It is believed that pain-responsive cells in the brain quiet down when these neurons also receive touch inputs, say scientists at MIT's McGovern Institute for Brain Research, who for the first time have watched this phenomenon play out in the brains of mice.

Opioid-involved car crashes decrease following efforts to curb use
The number of non-fatal car accidents that involve prescription opioids has dropped significantly in recent years, suggesting efforts to curb use are working. People taking prescription opioids are more than twice as likely to be involved in a car accident than those who aren-t, research has shown. In fact, between the early 1990s and early 2010s, as opioid use rose sharply in the United States, the number of fatalities among drivers using prescription opioids increased seven-fold.

Clouds less sensitive to climate than assumed
Trade wind cumulus clouds are found on about 20 percent of the globe and cool the planet. Until now, it was expected that these clouds would become fewer due to global warming and thus exacerbate climate change. A team led by Dr. Raphaela Vogel of the University of Hamburg has now been able to disprove this.

New AI method for public health analysis shows trends in substance use among high schoolers
University of Waterloo researchers take a novel approach to public health analysis High school students who have a large weekly allowance, friends who smoke and low levels of physical activity are more likely to use multiple substances over time. Conversely, being older, being Black and eating breakfast daily were factors associated with a smaller chance of transitioning to multiple use.

Gold from Troia, Poliochni and Ur had the same origin
The gold in objects from Troia, Poliochni - a settlement on the island of Lemnos, located about 60 kilometers off the coast of Troia - and Mesopotamian Ur has the same geographical origin and was traded over long distances. This is the conclusion reached by an international team of researchers who used an innovative mobile laser method to analyze samples of famous Early Bronze Age jewelry from Troia and Poliochni for the first time.

Alternative medicine loses the support of the main Spanish newspapers
Alternative medicine loses the support of the main Spanish newspapers
Researchers Lorena Cano Orón (University of Valencia) and Emilia H. Lopera Pareja (Energy, Environmental and Technological Research Centre) highlight that the media have changed from a mainly favourable attitude towards alternative medicine, a series of practices deviant from integrated medicine in the western health system, to another more sceptical.

U-M team recycles previously unrecyclable plastic
PVC, or polyvinyl chloride, is one of the most produced plastics in the United States and the third highest by volume in the world. Study: Using waste poly(vinyl chloride) to synthesize chloroarenes by plasticizer-mediated electro(de)chlorination PVC makes up a vast amount of plastics we use on a daily basis.

Researchers decrypt transport dynamics of porous media What laws govern how chemicals pass through filters? How do droplets of oil move through layers of stone? How do blood cells travel through a living organism? A team of researchers led by the Technical University of Munich (TUM) and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) has discovered how pore space geometry impacts transport of substances through fluids.

Organic cation transporters: study provides insights for the first time
Monoamines are neurotransmitters in the central and peripheral nervous systems and they also transmit signals between cells and the brain. This transmission is followed by their reuptake into the cells by means of transporters. While the specific monoamine transporters have already been well studied, not enough is known about the organic cation transporters, which are high-capacity monoamine transporters.

Open Science: data sharing struggling
Open Science: data sharing struggling
Despite mandatory data sharing policies adopted by some scientific journals, the potential for reuse of these data remains limited. This is the finding of a meta-research on open science undertaken by Dominique Roche, postdoctoral fellow in biology at the University of Neuchâtel. Open science is a worldwide movement to make scientific research and its data transparent and accessible to all.

Reliable planning tool for the emissions path to achieving the Paris temperature goal
Reliable planning tool for the emissions path to achieving the Paris temperature goal
Researchers at the University of Bern have developed a new method for the successive calculation of the emission reductions which are necessary for achieving temperature targets, such as the 2°C goal. The calculation method is based solely on observation rather than models and scenarios. According to the study, international climate policy has to become even more ambitious.

Important discovery could help extinguish disease threat to koalas
University of Queensland virologists are a step closer to understanding a mysterious AIDS-like virus that is impacting koala populations differently across state lines. Dr Michaela Blyton Associate Professor Keith Chappell from the Australian Institute for Bioengineering and Nanotechnology (AIBN) a School of Chemistry and Molecular Biosciences , have uncovered another piece of the puzzle in their quest to halt the koala retrovirus known as KoRV - a condition strongly associated with diseases that cause infertility and blindness.

Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe. The signal, named AT 2022cmc, was discovered earlier this year by the Zwicky Transient Facility in California. Findings published today in Nature Astronomy, suggest that it is likely from a jet of matter, streaking out from a supermassive black hole at close to the speed of light.

Silent synapses are abundant in the adult brain
Silent synapses are abundant in the adult brain
These immature connections may explain how the adult brain is able to form new memories and absorb new information. MIT neuroscientists have discovered that the adult brain contains millions of "silent synapses" - immature connections between neurons that remain inactive until they're recruited to help form new memories.

COPD patients have a higher risk of brain problems, possibly due to inflammation
Patients with chronic obstructive pulmonary disease (COPD) have a higher chance of suffering from brain-related problems such as anxiety, depression and memory problems. PhD candidate Charlotte Pelgrim discovered that inflammation in the brain and a less protective barrier of the blood vessels in the brain may play a role.
