A new study by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, University of Miami (UM) College of Arts and Sciences, and Valencia College analyzed the fossilized remains of clams to reconstruct the cooking techniques of the early inhabitants of Puerto Rico. The results showed that Puerto Ricans over 2,500 years ago were partial to roasting rather th
Thousands of Jewish physicians were stripped of their rights and murdered by the Nazis. Käthe Beutler fled with her family to the US and started all over again. An article about the life and work of the researcher, pediatrician, and mother is now appearing in the Medizinhistorisches Journal – plus the BIH’s Käthe Beutler Building is currently being built on the Berlin-Buch campus.
Hunger and undernutrition are widespread problems in Africa. At the same time, overweight, obesity, and related chronic diseases are also on the rise. Recent research suggested that the growth of supermarkets contributes to obesity in Africa. However, previous studies looked at data from adults. New research shows that supermarkets are not linked to obesity in children, instead contributing to a r
An international team led by Alexander Suh at Uppsala University has sequenced a chromosome in zebra finches called the germline-restricted chromosome (GRC). This chromosome is only found in germline cells, the cells that hold genetic information which is passed on to the next generation. The researchers found that the GRC is tens of millions of years old and plays a key role in songbird biology,
A new imaging technique developed by Biwei Yin and interdisciplinary researchers at the Massachusetts General Hospital and Harvard Medical School in the U.S., provides resolution at the subcellular-level to image the heart’s vascular system. As a result, heart researchers can study and diagnose human coronary artery disease with greater precision. Conventionally, cardiologists employ intravascular
Since the saltiness of ocean surface waters is a key variable in the climate system, understanding how this changes is important to understanding climate change. Thanks to ESA’s Climate Change Initiative, scientists now have better insight into sea-surface salinity with the most complete global dataset ever produced from space.
Heat from the landmass beneath the Antarctic ice sheet is a major contributor to the way that glaciers melt and flow—and their impact on potential sea level rise. Hotter conditions allow meltwater to lubricate the base of the glacier, accelerating its movement and the rate of ice loss.
In quantum physics, scrambling is the dispersal of quantum information across a complex quantum system, such as chaotic quantum many-body systems. This process can make quantum information difficult or impossible to access, particularly when using simple and conventional physics methods.
Antiretroviral drugs allow people with HIV to live completely normal lives. They also prevent them from transmitting the virus to others once they reach an undetectable viral load. It’s been almost 40 years since the start of the AIDS epidemic, when hundreds of people began contracting deadly infections that doctors had no idea how to combat. It took until 1983 for researchers to identify the vir
You can just tell they’re typing in caps lock about the $10 blender they bought on Black Friday. (Pixabay/) Now that Black Friday has devolved from a single day of bargain-driven mayhem into a month long slog of fake deals and annoying marketing, Cyber Monday has its chance to shine. Last year, shoppers spent an estimated $7.9 billion on Cyber Monday , which was a nearly 20 percent increase from
A protest in Belgium. (DepositPhotos/) It’s still possible to keep the worst effects of climate change at bay, according to a new United Nations (UN) report on the “emissions gap,” but only if we make dramatic and immediate cuts to our use of greenhouse gases around the world. Here’s what you need to know: What is the emissions gap? The UN has produces its emissions gap report annually ahead of t
In the film Dark Waters, corporate lawyer Robert Billott takes on an unusual client: West Virginia farmer Wilbur Tennant. Tennant’s cows began dropping dead after chemical company DuPont built a landfill upstream on the creek that the livestock drank from. Billott begins investigating the waste at the site, uncovering DuPont’s own internal research on a chemical called PFOA (perfluorooctanoic aci
The Great Red Spot isn’t as great as it once was. (NASA/JPL/) The solar system’s largest storm has raged on planet Jupiter for at least 200 years, in what many of us know as The Great Red Spot. That tempest, which once could have swallowed roughly three Earths, has looked a little thin these days, moving some to declare its total demise could occur within a couple decades. But some recent slimmin
Mesmerism was about more than just hypnosis. (Wikimedia Commons/) What’s the weirdest thing you learned this week? Well, whatever it is, we promise you’ll have an even weirder answer if you listen to PopSci’s hit podcast . The Weirdest Thing I Learned This Week hits Apple , Anchor , and everywhere else you listen to podcasts every Wednesday morning. It’s your new favorite source for the strangest
A new home urine test for prostate cancer could revolutionize diagnosis — according to new research. As well as diagnosing aggressive prostate cancer, the test predicts whether patients will require treatment up to five years earlier than standard clinical methods. It also means that men don’t have to come into the clinic to provide a urine sample — or have to undergo an uncomfortable rectal exa
The investigational therapeutics mAb114 and REGN-EB3 offer patients a greater chance of surviving Ebola virus disease (EVD) compared to the investigational treatment ZMapp. The new report also shows that early diagnosis and treatment are associated with an increased likelihood of survival from EVD.
Ancestors of modern bacteria cultured from an iron-rich lake in Democratic Republic of Congo could have been key to keeping Earth’s dimly lit early climate warm, and in forming the world’s largest iron ore deposits billions of years ago.
