Glug Glug Physics Of Bubble Dynamics Reveals How To Empty Bottles Faster

Bottle emptying is a phenomenon most of us have observed while pouring a beverage. Researchers from the Indian Institute of Technology Roorkee discovered how to make bottles empty faster, which has wide-ranging implications for many areas beyond the beverage industry. Bubbles have been studied extensively for centuries, including early efforts by Leonardo da Vinci who famously noted the sinusoidal rise of bubbles within a pool. The growth dynamics of bubbles at the mouth of a bottle depend on the thermophysical properties of the fluid, the bottle geometry, and its angle of inclination....

Green And Economical Underground Storage Of Carbon Captured Directly From Air

The global threat of ongoing climate change has one principal cause: carbon that was buried underground in the form of fossil fuels is being removed and released into the atmosphere in the form of carbon dioxide (CO2). One promising approach to addressing this problem is carbon capture and storage: using technology to take CO2 out of the atmosphere to return it underground. In a new study published in Greenhouse Gases Science and Technology, researchers from Kyushu University and the National Institute of Advanced Industrial Science and Technology, Japan, investigated geological storage of low-purity CO2 mixed with nitrogen (N2) and oxygen (O2), produced by direct air capture (DAC) using membrane-based technology....

Growth Promoting Anti Aging Chemical Compound At The Root Of Plant Growth And Animal Embryos

What do frog eggs have in common with anti-aging creams? Their success depends on a group of chemical compounds called retinoids, which are capable of generating and re-generating tissues. A new study in plants shows that retinoids’ tissue-generating capacities are also responsible for the appropriate development of roots. If you’ve ever planted a radish seed, you know that the first thing it does is develop a long vertical root. Give it a bit more time, and it will get smaller roots that run perpendicular to the plant’s stem....

Harvard Doctors Reveal Startling Truth Do Football Players Age Faster

A new study published in the British Journal of Sports Medicine reveals that former professional football players, particularly linemen, have a higher likelihood of developing age-related diseases at a younger age in comparison to non-players with similar demographic characteristics. These diseases include hypertension, diabetes, among others. The research also showed that the health span of these athletes was reduced by almost a decade when compared to the general population. Notably, the effects persisted even after the researchers accounted for body mass index and race, two powerful risk factors for the diseases studied....

Heart Disease Good Cholesterol May Not Be Good For Everyone

Lower levels of HDL cholesterol were associated with increased risks for heart attacks in white but not black adults, and higher levels were not protective for either group. A study found that high-density lipoprotein (HDL) cholesterol, often called the “good cholesterol,” may not be as effective as scientists once believed in uniformly predicting cardiovascular disease risk among adults of different racial and ethnic backgrounds. The study was supported by the National Institutes of Health (NIH)....

How Airports Will Influence The Spread Of A Contagious Disease

Public health crises of the past decade — such as the 2003 SARS outbreak, which spread to 37 countries and caused about 1,000 deaths, and the 2009 H1N1 flu pandemic that killed about 300,000 people worldwide — have heightened awareness that new viruses or bacteria could spread quickly across the globe, aided by air travel. While epidemiologists and scientists who study complex network systems — such as contagion patterns and information spread in social networks — are working to create mathematical models that describe the worldwide spread of disease, to date these models have focused on the final stages of epidemics, examining the locations that ultimately develop the highest infection rates....

How Deep Sea Ultra Black Fish Disappear Science Behind Skin That Absorbs More Than 99 5 Of Light

Deep in the ocean, where sunlight barely reaches, Smithsonian scientists and a team of collaborators have discovered one of the blackest materials known: the skin of certain fish. These ultra-black fish absorb light so efficiently that even in bright light they appear to be silhouettes with no discernible features. In the darkness of the ocean, even surrounded by bioluminescent light, they literally disappear. In the July 16 issue of the journal Current Biology, a team of scientists led by Smithsonian’s National Museum of Natural History research zoologist Karen Osborn and Duke University biologist Sönke Johnsen report on how a unique arrangement of pigment-packed granules enables some fish to absorb nearly all of the light that hits their skin, so that as little as 0....

Hubble Captures Sizzling Hot Giant Star On The Edge Of Destruction Shining With The Brilliance Of 1 Million Suns

Its opulence means that the mammoth star is living life in the fast lane. Pouring out so much energy takes a toll on the stellar behemoth. It is prone to convulsive fits, expanding in size like a hot air balloon and shedding its outer layers of material into space. One or more giant eruptions 10,000 years ago created the beautiful, expanding shell of dust and gas seen here. Stars like this one are rare: less than 50 reside in our local group of neighboring galaxies....
