A gold miner in Canada discovered a near complete mummified baby woolly mammoth Tuesday, according to the Yukon government and Trʼondëk Hwëchʼin, a local traditional territory. The female baby was named Nun cho ga, which means “big baby animal” in the Hän language.

The miner found the baby, which retained its skin and hair, while excavating through the permafrost at Eureka Creek in the Klondike gold fields within Trʼondëk Hwëchʼin Traditional Territory, the government’s press release said. She’s estimated to have frozen during the Ice Age, over 30,000 years ago. While alive, she likely roamed the Yukon with wild horses, cave lions and giant steppe bison.

It added that the discovery was “significant” and rare, even for an area like Yukon, which has “a world-renowned fossil record of ice age animals.”

Typhoid fever might be rare in developed countries, but this ancient threat, thought to have been around for millennia, is still very much a danger in our modern world.

According to new research, the bacterium that causes typhoid fever is evolving extensive drug resistance, and it’s rapidly replacing strains that aren’t resistant.

Currently, antibiotics are the only way to effectively treat typhoid, which is caused by the bacterium Salmonella enterica serovar Typhi (S Typhi). Yet over the past three decades, the bacterium’s resistance to oral antibiotics has been growing and spreading.

Early diagnosis of neurodevelopmental conditions, such as Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD), is critical for treatment and symptom management processes.

Now, a team of researchers from the University of South Australia has found that recordings from the retina may be used to distinguish unique signals for both ADHD and ASD, offering a possible biomarker for each disorder. According to a press release published by the institution, The team used the “electroretinogram” (ERG), a diagnostic test that measures the electrical activity of the retina in response to light, and found out that children with ASD showed less ERG energy while children with ADHD displayed more ERG energy.

As they grow, solid tumors surround themselves with a thick, hard-to-penetrate wall of molecular defenses. Getting drugs past that barricade is notoriously difficult. Now, scientists at UT Southwestern have developed nanoparticles that can break down the physical barriers around tumors to reach cancer cells. Once inside, the nanoparticles release their payload: a gene editing system that alters DNA inside the tumor, blocking its growth and activating the immune system.

The new , described in Nature Nanotechnology, effectively stopped the growth and spread of ovarian and liver tumors in mice. The system offers a new path forward for the use of the gene editing tool known as CRISPR-Cas9 in , said study leader Daniel Siegwart, Ph.D., Associate Professor of Biochemistry at UT Southwestern.

“Although CRISPR offers a new approach for treating , the technology has been severely hindered by the low efficiency of delivering payloads into tumors,” said Dr. Siegwart, a member of the Harold C. Simmons Comprehensive Cancer Center.

It started with JPL agreeing to land something on Mars – cheaply – and do it in a radically different way. This is how the era NASA called “Faster, Better, Cheaper” began. The documentary film “The Pathfinders” tells the story of a small group of engineers at NASA’s Jet Propulsion Laboratory who did not heed warnings that the audacious challenge of landing on Mars with airbags would likely not be a career-enhancing move.

From relying on a parachute that could not be tested in a way to match the Martian atmosphere to receiving the late addition of an unwanted rover that wouldn’t have looked out of place in a toy store, the Mars Pathfinder mission was a doubter’s dream, taken on by a mostly young group of engineers and scientists guided by a grizzled manager known for his maverick ways.

“The Pathfinders” retraces the journey of this daring mission to Mars that captured the imagination of people around the world with its dramatic landing and its tiny rover – the first wheels ever to roll on Mars.

Documentary length: 60 minutes.

While electric vehicles promise a green future, the batteries that power them don’t boast the same level of sustainability.

While driving electric vehicles is a step towards a greener future, the car batteries that power them are not as sustainable. Though the battery is at the heart of any EV, most are made from lithium-ion and have a limited lifespan that starts to degrade from the first time you charge them. So what happens when they reach capacity?

The cycle of charging and discharging causes them lose energy and power. The more charge cycles a battery goes through, the faster it will degrade. Once batteries reach 70 or 80% of their capacity, which happens around either 5 to 8 years or after 100,000 miles of driving, they have to be replaced, according to Science Direct.

Due to electric vehicles’ rising popularity, it goes without saying that their battery waste will become a major issue. Experts estimate that 12 million tons of batteries will be thrown away by 2030, The Guardian reported. The conundrum that manufacturers and consumers have is that although they can be recycled, there are not enough facilities to handle them. To date, there are only four lithium-ion recycling centers in the United States (via WCNC). However, this number must grow exponentially in the next few years as Industry experts predict there will be 85 million electric vehicles on the road by 2030 (via Science Direct).
