Imagine you sit down and pick up your favourite book. You look at the image on the front cover, run your fingers across the smooth book sleeve, and smell that familiar book smell as you flick through the pages. To you, the book is made up of a range of sensory appearances.

But you also expect the book has its own independent existence behind those appearances. So when you put the book down on the coffee table and walk into the kitchen, or leave your house to go to work, you expect the book still looks, feels, and smells just as it did when you were holding it.

Expecting objects to have their own independent existence – independent of us, and any other objects – is actually a deep-seated assumption we make about the world. This assumption has its origin in the scientific revolution of the 17th century, and is part of what we call the mechanistic worldview. According to this view, the world is like a giant clockwork machine whose parts are governed by set laws of motion.

A team led by astronomers at UC Santa Barbara have confirmed the existence of an elusive new type of supernova.

A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion — an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. They are thought to arise from the explosions of massive super-asymptotic giant branch (SAGB) stars, for which there has also been scant evidence. The discovery, published in Nature Astronomy, also sheds new light on the thousand-year mystery of the supernova from A.D. 1054 that was visible all over the world in the daytime, before eventually becoming the Crab Nebula.

Historically, supernovae have fallen into two main types: thermonuclear and iron-core collapse. A thermonuclear supernova is the explosion of a white dwarf star after it gains matter in a binary star system. These white dwarfs are the dense cores of ash that remain after a low-mass star (one up to about 8 times the mass of the sun) reaches the end of its life. An iron core-collapse supernova occurs when a massive star — one more than about 10 times the mass of the sun — runs out of nuclear fuel and its iron core collapses, creating a black hole or neutron star. Between these two main types of supernovae are electron-capture supernovae. These stars stop fusion when their cores are made of oxygen, neon and magnesium; they aren’t massive enough to create iron.

Changes in epigenetic age acceleration (EAA) were significant over time, with the biggest increase — 4.9 years — seen immediately after the completion of radiotherapy (PChanges in epigenetic age acceleration (EAA) were significant over time, with the biggest increase — 4.9 years — seen immediately after the completion of radiotherapy (P0.001), reported Canhua Xiao, RN, PhD, of Emory University School of Nursing in Atlanta, and colleagues.

The study also demonstrated that EAA was associated with greater inflammation and fatigue, even up to a year after treatment, they noted in Cancer.

While chronological age is a strong risk factor for chronic health problems, Xiao and colleagues said that it often differs from epigenetic age and may be a limited predictor of age-associated disorders. On the other hand, they noted that epigenetic clocks, based on blood DNA methylation measures, have become reliable aging biomarkers.

Plans call for the 289-meter-tall (954-foot-tall) Baihetan Dam to have 16 generating units with a capacity of 1 million kilowatts each. That will make it second in size after the Three Gorges Dam, opened in 2003 on the Yangtze, with 22.5 million kilowatts of generating capacity.

BEIJING (AP) — The first two generating units of the world’s second-biggest hydroelectric dam were officially turned on Monday in southwestern China, the government announced.

The Baihetan Dam on the Jinsha River, a tributary of the Yangtze, is part of Chinese efforts to curb surging fossil fuel demand by building more hydropower capacity at a time when dams have fallen out of favor in other countries due to environmental complaints.

If concerned, speak to your physician.

In patients with mild cognitive impairment, taking lipophilic statins more than doubles their risk of developing dementia compared to those who do not take statins. According to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting, positron emission tomography (PET) scans of lipophilic statin users revealed a highly significant decline in metabolism in the area of the brain that is first impacted by Alzheimer’s disease.

Statins are medications used to lower cholesterol and reduce the risk of heart attack or stroke. They are the most commonly used drugs in the developed world, and nearly 50 percent of Americans over age 75 use a statin. Different types of statins are available based on a patient’s health needs, including hydrophilic statins that focus on the liver and lipophilic statins that are distributed to tissues throughout the body.

When Tesla unveiled its new Plaid Model S earlier this month, it took the world by storm, fueling dreams of speed, racing, and fun. In the sense of a grand finale to Tesla’s event, another event was talked about in the weeks following. That event was the annual race to the summit of Pikes Peak. Also known as “The Race to the Clouds,” the entire track winds through 156 turns over 12.42 miles as it reaches the summit of Pikes Peak.

Researchers at McMaster University have developed a promising new cancer immunotherapy that uses cancer-killing cells genetically engineered outside the body to find and destroy malignant tumors.

The modified “natural killer” cells can differentiate between cancer cells and healthy cells that are often intermingled in and around tumors, destroying only the targeted cells.

The natural killer cells’ ability to distinguish the target cells, even from healthy cells that bear similar markers, brings new promise to this branch of immunotherapy, say members of the research team behind a paper published in the current issue of the journal iScience, newly posted on the PubMed database.
