Chemical breakthrough shields mitochondrial DNA before damage triggers chronic disease

INTERESTING ENGINEERING - From Alzheimer’s to heart failure, many chronic diseases have been linked to damage in mitochondrial DNA (mtDNA). Now, scientists at the University of California, Riverside, may have found a way to halt the damage before it begins. The team has developed a chemical probe that targets damage in mitochondrial DNA (mtDNA), a...

Scientists find a surprising case of 'reverse evolution' in wild tomatoes

EARTH.COM - Wild tomatoes rooted on the raw lava of Fernandina and Isabela Islands have done something biologists once filed under “nearly impossible,” reviving a molecular defense that disappeared from their relatives millions of years ago during species evolution. The phenomenon has been traced to a tiny tweak in the plants’ chemistry, and it now...

Physicists learn to control electricity at the quantum scale

EARTH.COM - Today’s flagship processor packs more than 100 billion transistors, yet squeezing them any closer is turning design into a wrestling match with quantum physics. As the footprints of silicon switches approach the dimensions of a few dozen atoms, stray electrons tunnel across barriers that once looked rock‑solid, wasting power and scrambling signals. Physicists...

Scientists discover Galápagos tomatoes evolving backwards, bringing back ancient traits lost millions of years

DAILY GALAXY - In an unexpected discovery, researchers have found that wild tomatoes in the Galápagos Islands seem to be evolving in reverse. This fascinating phenomenon, previously thought to be rare, suggests that evolution isn’t always a straightforward process. The finding, which challenges conventional wisdom, could lead to exciting breakthroughs in genetic research. Tomatoes Turning...

Some tomatoes are evolving backwards in real time, scientists find

POPULAR MECHANICS - The famous ape-to-man illustration, known as The March of Progress, depicts evolution as a one-way street toward evolutionary perfection—but nature isn’t always so simple. Many organisms have displayed what appears to be “reverse evolution,” or regression, where ancient attributes of past ancestors seem to reappear down the evolutionary line. Cave fish, for...

Something strange is happening to tomatoes growing on the Galápagos Islands

SMITHSONIAN MAGAZINE - Some tomatoes growing on the Galápagos Islands appear to be going back in time by producing the same toxins their ancestors did millions of years ago. Scientists describe this development—a controversial process known as “reverse evolution”—in a June 18 paper published in the journal Nature Communications. Tomatoes are nightshades, a group of...

These wild tomatoes are reversing millions of years of evolution

ZME SCIENCE - On the Galápagos Islands, wild tomatoes are producing molecules not seen since the Ice Age, reversing a genetic trajectory millions of years in the making. In a study published in Nature Communications, researchers from the University of California, Riverside and the Weizmann Institute of Science have documented a rare and striking example...

Retro tomatoes: a species of the plant is evolving backward

THE WEEK - Some tomatoes have evolved to possess the characteristics of their ancestors. While it is rare, there have been instances of species displaying traits from further back in evolution. But for the first time, scientists have now been able to prove it through genetic evidence. And there's potential for similar evolutionary changes in...

New system attracts and eliminates termites with a natural scent and no toxins

EARTH.COM - Sagging beams and hollow‑sounding walls can signal a menace that quietly drains bank accounts around the world – termites. Building owners and insurers spend close to $5 billion a year fixing damage and fighting infestations. Now, a team of researchers led by Dong‑Hwan Choe at the University of California, Riverside (UCR) say they...

Scientists shed light on the mysterious 'cold blob' in the North Atlantic amid a search for its cause

SMITHSONIAN MAGAZINE - Just south of Greenland, in the northern Atlantic Ocean, a strange area of water has been confounding scientists for years. While the rest of the ocean warms, that patch has been mysteriously cooling. Researchers have offered different theories behind this “cold blob,” such as changes in ocean circulation patterns or aerosol pollution...

The Atlantic's major circulation current is showing worrying signs, but is collapse near?

IFLSCIENCE - Something’s stirring in the Atlantic Meridional Overturning Circulation (AMOC) – and a strange “hole” of cold water in the North Atlantic may provide new clues about what’s up. But is the system on the brink of full-blown collapse, or will it keep churning on despite mounting pressure? The AMOC is “the conveyor belt...

A plague of pests is coming for California. Here’s how to stop it.

THE NEW YORK TIMES - Back in the late 1880s, California citrus farmers found themselves dealing with a crisis caused by a fat bug covered in a shieldlike, granular white wax. Known as the cottony cushion scale, this insect, which had hitchhiked aboard ships from Australia, usually spends its entire life with its mouth affixed...

Physicists solve a 50-year mystery about a critically important molecule

GIZMODO - After relying on an educated guess for decades, scientists have finally confirmed the dipole moment of aluminum monochloride (AlCl), an elusive but important molecule known to sneak around the interiors of ancient galaxies. An electric dipole moment is a measure of polarity—a crucial determinant for many physical properties of any system, such as...

A Mysterious Blob of Cold Water Defies Ocean Heat – Now We Know Why

SCIENCE ALERT - Over the last decade, Earth's oceans have been warming at unprecedented rates, yet one mysterious blob of water, just south of Greenland, has defied this trend. It has stubbornly remained colder than its surrounding waters for over a century now. "People have been asking why this cold spot exists," says University of...

Meet the tomatoes that are evolving backwards – with a toxic twist

NEW ATLAS - The evolutionary ladder is meant to be climbed one rung at a time with an organism shedding some traits and gaining others on the way up. However, in a very surprising twist, some tomatoes on the Galapagos islands are inching back down the ladder. When they found the backwards-reaching plants, researchers from...

Reverse evolution? These wild tomatoes are turning back time

EARTH.COM - Evolution is taking an unexpected turn on the volcanic islands of the western Galápagos. Wild tomato plants are producing a toxic blend of chemicals that hasn’t existed in their species for millions of years. Somehow, these plants have started making molecules more like eggplants than the modern tomato. This bizarre twist in evolution...

These plants might actually be de-evolving

BGR - We know that the world and its various inhabitants, from plants to animals, are still evolving. In fact, some even believe that humans are actively evolving in different parts of the world right now. But a group of plants found in the Galápagos archipelago might be doing the opposite and de-evolving. Researchers argue...

Evolution experts say wild tomatoes in Galápagos are going 'back in time'

BBC WILDLIFE MAGAZINE - Evolution is commonly thought of as a process that creates new and more complicated traits. But this is not always the case. On the youngest islands of the Galápagos archipelago, wild tomato plants have adapted to their environment by producing toxins identical to those used by their ancestors millions of years...

Mystery behind cold blob in the Atlantic Ocean finally solved

LIVE SCIENCE - Researchers have finally answered a longstanding question about a giant patch of cold water in the Atlantic Ocean, blaming a change in ocean currents for the unexpected cooling. The anomaly, located just south of Greenland, is — perhaps counterintuitively — called the North Atlantic Warming Hole, and it has been stumping scientists...

Evolution Running Backwards? Thats What This Unlikely Organism Appears To Be Doing

IFLSCIENCE - We typically think of evolution as progressing in one direction, with a species getting “better” and “better” as it goes. But evolution is far more complex than that, as has recently been illustrated by an unusual organism: Galápagos tomatoes. These wild-growing fruits are shedding millions of years of evolution in order to reproduce...
