Commuters are inhaling unacceptably high levels of carcinogens

Twenty minutes or longer in the car also raises risk of birth defects

Commuters are inhaling unacceptably high levels of carcinogens
2021-02-15
(Press-News.org) A new study finds that California's commuters are likely inhaling chemicals at levels that increase the risk for cancer and birth defects.

As with most chemicals, the poison is in the amount. Under a certain threshold of exposure, even known carcinogens are not likely to cause cancer. Once you cross that threshold, the risk for disease increases.

Governmental agencies tend to regulate that threshold in workplaces. However, private spaces such as the interior of our cars and living rooms are less studied and less regulated.

Benzene and formaldehyde -- both used in automobile manufacturing -- are known to cause cancer at or above certain levels of exposure and are Prop. 65-listed chemicals.

New UC Riverside research shows that the average commuter in California is exceeding the threshold for exposure, breathing in unsustainably high levels of both chemicals.

Both benzene and formaldehyde are carcinogens, and benzene carries the additional risk of reproductive and developmental toxicity.

"These chemicals are very volatile, moving easily from plastics and textiles to the air that you breathe," said David Volz, UCR professor of environmental toxicology.

The study, published in the journal END

Strange creatures accidentally discovered beneath Antarctica's ice shelves

Strange creatures accidentally discovered beneath Antarcticas ice shelves
2021-02-15
Far underneath the ice shelves of the Antarctic, there's more life than expected, finds a recent study in the journal Frontiers in Marine Science. During an exploratory survey, researchers drilled through 900 meters of ice in the Filchner-Ronne Ice Shelf, situated on the south eastern Weddell Sea. At a distance of 260km away from the open ocean, under complete darkness and with temperatures of -2.2°C, very few animals have ever been observed in these conditions. But this study is the first to discover the existence of stationary animals - similar to sponges and potentially several previously unknown species - attached to a boulder on the sea floor. "This discovery is one of those ...

Parents Say COVID-19 has disrupted children's dental care

Parents Say COVID-19 has disrupted childrens dental care
2021-02-15
ANN ARBOR, Mich. - A third of parents say the COVID-19 pandemic has made it difficult to get dental care for their children, a new national poll suggests. But some families may face greater challenges than others. Inability to get a dentist appointment during the pandemic was three times as common for children with Medicaid versus those with private dental coverage, according to the C.S. Mott Children's Hospital National Poll on Children's Health at Michigan Medicine. "Regular preventive dental care helps keep children's teeth healthy and allows providers to address any tooth decay ...

Peeking at the pathfinding strategies of the hippocampus in the brain

Peeking at the pathfinding strategies of the hippocampus in the brain
2021-02-15
We find routes to destination and remember special places because there is an area somewhere in the brain that functions like a GPS and navigation system. When taking a new path for the first time, we pay attention to the landmarks along the way. Owing to such navigation system, it becomes easier to find destinations along the path after having already used the path. Over the years, scientists have learned, based on a variety of animal experiments, that cells in the brain region called hippocampus are responsible for spatial perception and are activated in discrete positions ...

Membrane building blocks play decisive role in controlling cell growth

Membrane building blocks play decisive role in controlling cell growth
2021-02-15
Lipids are the building blocks of a cell's envelope - the cell membrane. In addition to their structural function, some lipids also play a regulatory role and decisively influence cell growth. This has been investigated in a new study by scientists at Martin Luther University Halle-Wittenberg (MLU). The impact of the lipids depends on how they are distributed over the plasma membrane. The study was published in "The Plant Cell". If plant cells want to move, they need to grow. One notable example of this is the pollen tube. When pollen lands on a flower, the pollen tube grows directionally into the female reproductive organs. This allows the male gametes to be delivered, so fertilisation can occur. The pollen tube is special ...

Capuchin monkey genome reveals clues to its long life and large brain

2021-02-15
An international team of scientists has sequenced the genome of a capuchin monkey for the first time, uncovering new genetic clues about the evolution of their long lifespan and large brains. Published in PNAS, the work was led by the University of Calgary in Canada and involved researchers at the University of Liverpool. "Capuchins have the largest relative brain size of any monkey and can live past the age of 50, despite their small size, but their genetic underpinnings had remained unexplored until now," explains Professor Joao Pedro De Magalhaes, who researches ageing at the University of Liverpool. The researchers developed and annotated a reference assembly for white-faced ...

Aspirin preferred to prevent blood clots in kids after heart surgery

Aspirin preferred to prevent blood clots in kids after heart surgery
2021-02-14
Aspirin should be favoured over warfarin to prevent blood clotting in children who undergo a surgery that replumbs their hearts, according to a new study. The research, led by the Murdoch Children's Research Institute (MCRI) and published in The Journal of Thoracic and Cardiovascular Surgery, will have implications for clinicians when prescribing blood thinning medications after Fontan surgery, a complex congenital heart disease operation redirecting blood flow from the lower body to the lungs. The Fontan procedure is offered to children born with severe heart defects, allowing the child to live with just one pumping heart chamber ...

Cabozantinib most effective treatment for metastatic papillary kidney cancer

Cabozantinib most effective treatment for metastatic papillary kidney cancer
2021-02-13
In a SWOG Cancer Research Network trial that put three targeted drugs to the test, the small molecule inhibitor cabozantinib was found most effective in treating patients with metastatic papillary kidney cancer - findings expected to change medical practice. These findings will be presented at ASCO's virtual 2021 Genitourinary Cancers Symposium on Feb. 13, 2021 at 1 p.m. ET. The findings will be simultaneously published in The Lancet. There are currently no effective treatments for metastatic papillary kidney cancer, or metastatic pRCC, a rare subtype of kidney cancer. One study of 38 patients found that the average survival ...

Immunotherapy -- targeted drug combination improves survival in advanced kidney cancer

2021-02-13
Lenvatinib plus pembrolizumab yields better overall survival than single-agent sunitinib when given as first-line therapy in untreated patients with metastatic kidney cancer The combination also improved progression-free survival and overall response rate BOSTON - Patients with advanced kidney cancer, who received a targeted drug combined with a checkpoint-blocker immunotherapy agent had longer survival than patients treated with the standard targeted drug, said an investigator from Dana-Farber Cancer Institute, reporting results from a phase 3 clinical trial. The survival benefit demonstrates that an immune checkpoint inhibitor together with a targeted kinase inhibitor drug "is important ...

Gene-based blood test for melanoma spread evaluates treatment progress

2021-02-13
A test that monitors blood levels of DNA fragments released by dying tumor cells may serve as an accurate early indicator of treatment success in people in late stages of one of the most aggressive forms of skin cancer, a new study finds. Led by NYU Grossman School of Medicine and Perlmutter Cancer Center researchers, the investigation looked at adults with undetectable levels of freely circulating tumor DNA (ctDNA) four weeks into drug treatment for metastatic melanoma tumors that cannot be removed surgically (unresectable). The study showed that these patients, all of whom had common genetic changes (BRAFV600 mutations) linked to cancer, were living ...

The Lancet: COVID-19 vaccination potential will not be achieved without increased production, affordable pricing, global availability, and successful rollout

2021-02-13
Peer-reviewed / Review, Survey and Opinion piece To ensure an effective global immunisation strategy against COVID-19, vaccines need to be produced at scale, priced affordably, and allocated globally so that they are available where needed, and successfully rolled out. Review of evidence includes a comparison of 26 leading vaccines on their potential contribution to achieving global vaccine immunity, and a new survey of COVID-19 vaccine confidence in 32 countries. Having new COVID-19 vaccines will mean little if people around the world are unable to get vaccinated in a timely manner. ...
