On Sept. 14, 2020, a new planet was added to the list of potentially habitable worlds in the Solar System: Venus.
(Inside Science) -- For the first time, an intact world may have been discovered around a white dwarf, suggesting that even after typical stars die, they may still host planets, a new study finds.
White dwarfs are the cooling Earth-size cores of dead stars left behind after average-size stars have exhausted their fuel and shed their outer layers. Our sun will eventually fade into a white dwarf after first bloating to become a red giant. The same fate awaits more than 90% of the stars in our galaxy.
Even then, diets would have to change, because progress has meant having diversity and choice, and if locally-grown were really necessary, the population would starve along the Eastern Seaboard and the Southwest of the U.S. And meat would only be for the rich.
Surrogate Sires: CRISPR Pigs And Cattle Could Produce Sperm Carrying Only The Genetic Traits Of Donor Animals
Now, with desire to optimize food production and reduce environmental impact without harming choices for poor people, scientists have created pigs, goats and cattle that can serve as viable “surrogate sires” - male animals that produce sperm carrying only the genetic traits of donor animals.
COVID-19 Has Been A Gold Rush For Journals - But Media Coverage Of The 'Infodemic' May Confuse The Public
If any of the above are true, you have been reading too much corporate media and witnessed coverage that they can claim is resulting from peer-reviewed journals.
Muscles shrink and their strength dwindles as we age. When that is excessive, the condition is called sarcopenia, and it affects every third person over the age of 80, reducing mobility, autonomy and quality of life.
There may be hope in the form of a well-known drug, Rapamycin, that can delay the progression of age-related muscle weakness.
There is a lot more isolation than in past pandemics but also a lot more community around SARS-CoV-2, the 2019 form of the coronavirus that has locked up most developed countries. Unlike the past, where nature was just trying to kill us, and the randomness of it all caused panic, people know where it originated and how. We know how to mitigate it. We are equipped to try and help those with co-morbidities. A lot of people have died, no one downplays that, but a lot fewer than in any pandemic ever.
There’s a thin line between working hard enough and working too hard. Pushing your body to reach new levels of fitness requires commitment, effort and a willingness to put yourself through intense, challenging workouts on a regular basis.
But more isn’t always better. Without the right balance of rest and recovery you could end up spiralling into a long-term fatigue condition called overtraining syndrome. The condition results in long-term reduced physical performance, and may be accompanied by other physiological and psychological symptoms (such as low mood or poor sleep) – though this isn’t always the case. It can take weeks, months and even years to recover from this condition.
Climate Change: Engineering Models Hope For Best Outcomes - And Any Chess Player Knows That's Terrible Strategy
The model used a best-case scenario, which any entry-level chess player knows is a bad idea - they forgot to falsify their own hypothesis in their zeal to do something. A new paper notes that many ambitious climate action plans rely on climate engineering technologies where the risks are unknown. They are more like TED talks than real plans.
It is proof-of-concept for how future models can overcome limitations of prior brain-computer interface efforts, which existing had to be reset and recalibrated each day, almost like asking someone to learn to ride a bike over and over again each day.
Independent Frontier Mentality Still Exists In Modern Mountain Regions - And With It Less Neuroticism
A new paper finds that people who live in mountain regions of the U.S. maintain more of that sensibility even in the modern era. Historian Frederick Jackson Turner, a Harvard academic, presented his thesis on the US frontier in 1893, describing the "coarseness and strength combined with acuteness and acquisitiveness" it had forged in the American character.
Charcoal is not exclusive to American blended whiskey, this type of filtration is a common step in the production of distilled beverages, including vodka and rum, but while "charcoal mellowing" in Tennesse Whiskey varies from manufacturer to manufacturer, they all involve passing the fresh whiskey distillate through a bed of charcoal, usually derived from burnt sugar maple, prior to barrel-aging the product.
The reopening of cafes has been one of the highlights of relaxed COVID-19 restrictions for many Australians. During lockdowns, long queues for takeaway coffee were testimony to caffeine’s relevance to our lives.
Almost deprived of vegetation, the Lut desert harbors a diverse animal life, but no permanent aquatic biotops, such as ponds. Instead, after rain falls, non-permanent astatic water bodies are filled including the Rud-e-Shur river from north-western Lut. And that is when these new creatures can be more readily found.
For the study, 312 honeybees and bumblebees in Perth Western Australia, Ireland and England, were used to test the effect of the venom on the clinical subtypes of breast cancer, including triple-negative breast cancer, which has limited treatment options.
