A strange pregnancy puzzled doctors in Australia. An initial ultrasound showed two embryos sharing a placenta, which normally indicates monozygotic, or identical, twins. But weeks after, another ultrasound revealed the two fetuses had different sexes, a seeming contradiction to the earlier discovery.
On March 8, the first flight of the SpaceX Crew Dragon landed 200 miles off the coast of Florida at 8:45 a.m. Demo-1, as the flight was called, was launched on March 2 and spent a short, five-day visit at the International Space Station (ISS) before returning back to Earth.
In a statement issued on Feb. 28, the Food and Drug Administration (FDA) cautioned against using robotically-assisted surgical devices in surgeries like mastectomies and other cancer-related illnesses that specifically affect women’s health.
The flood of false information about vaccines spreading through social media has contributed to decreases in vaccination rates and increases in the number of cases of preventable communicable disease, according to Simon Stevens, chief executive officer of the National Health Service (NHS) in England.
Somewhere around puberty, everyone spent a good chunk of their life listening to some adult teach about the wonders of the human body. The physical differences are obvious: males tend to have more facial hair, females are generally shorter and have more delicate facial features. The subtle differences are harder to catch, but still noticeable. Males tend to be louder and more aggressive while females are more emotional. Psychologically, there is a dichotomy between behaviors that men versus women exhibit, and researchers may have found a reason why.
Researchers at the University of Bath have found that skin cells from individuals with the rare genetic disorder Friedrich’s Ataxia are four to 10 times more likely to be damaged by ultraviolet A (UVA) radiation than those without the disorder. A newly synthesized molecule may provide protection when used as a sunscreen additive.
In a now decades-old interview with Gloria Steinem, Sally Ride discussed the barrage of sexist comments she fielded from members of the press, as the first American woman to travel to space. Ride recalled how the news media focused not on her abilities, skills or qualifications, but derailed interviews to remark on her makeup, physique and reproductive organs. Living in 2019, it’s tempting to dismiss such interactions as cringeworthy reminders of a seemingly distant past. Sadly, however, media coverage of women in STEM remains problematic.
When planet Earth was formed almost 4.6 billion years ago following an expansion event known as the Big Bang, it was not exactly conducive to supporting the survival of life. Earth emerged from a hot mix of gases and solids as a celestial body without an atmosphere, which eventually developed as the earth cooled. This early atmosphere was comprised of hydrogen sulfide, methane and 10 to 200 times as much carbon dioxide as there is in today’s atmosphere.
The Hayabusa2 spacecraft finally landed on the near-Earth asteroid Ryugu on Feb. 21, 2019. This was no easy feat. The Hayabusa2’s main body measures about 1 x 1.25 x 1.6 meters (m) in size and weighs 609 kilograms (kg). Launched in December 2014, Hayabusa2 managed to land as planned about four years later on an asteroid no bigger than one kilometer (km) in diameter, orbiting over hundreds of millions of kilometers away from earth.
Neurocognitive disorders have become more and more prevalent in society. Cognitive disorders can be defined as any disorder that significantly impairs the cognitive function of an individual in motor coordination, learning and memory, and impaired judgement. These disorders make it impossible to function normally in everyday life.
An international team of researchers from institutions in the United States, Russia and Portugal recently achieved the feat of decoding the great white shark’s entire genome. After doing so, the team proceeded to compare the great white’s genome to that of other species such as whale sharks and humans.
The Trump administration submitted a rule to bar groups which offer abortions or provide abortion referrals from partaking in Title X funding. It was first introduced in May 2018 and was submitted on Feb. 7 to the Office of Information and Regulatory Affairs for final review.
In 2017, the U.S. Department of Health and Human Services (HHS) declared a public health emergency regarding the opioid epidemic in the U.S. While recent data shows that death rates have been dropping in recent years, data has also shown that opioid abuse related deaths still seem to be much more common in some states than others.
A new study has found a drastic decline in great white shark sightings around Seal Island in False Bay, south of Cape Town, South Africa.
A soda tax may be an effective way to curb rates of diabetes, heart disease and obesity. According to a study in the American Journal of Public Health conducted by the University of California, Berkeley (UC Berkeley), the consumption of sugary drinks dropped 52 percent among low-income Berkeley residents.
The discussion about end-of-life care often centers around the value of invasive surgeries and that of palliative care, which is designed to treat symptoms rather than the cause of illness. One treatment that is rarely referred to as voluntary is kidney dialysis, which is defined by the National Kidney Foundation as treatment that includes the removal of waste, salt and extra water to prevent them from building up in the body; the maintenance of a safe level of potassium, sodium and bicarbonate in the blood; and control of blood pressure.
During our days in elementary school science, most of us learned the basics of geology. We learned about the layers of the earth (crust, mantle, outer and inner core) and plate tectonics, among other topics. However, this was a great oversimplification of all that goes on under our feet.
Finding a cure for cancer is one of the most highly researched topics in science because of its major impact all over the world. According to the National Cancer Institute, in 2018, there was an estimated 1.7 million new cases of cancer diagnosed in the United States and approximately 17 million new cases worldwide.
Clinical trials are essential for testing new medications because they let researchers know whether new medications, from vitamins to vaccines, are safe and effective. However, a new study published in Trials shows that researchers aren’t properly reporting the outcomes of their clinical trials. This may make a new treatment appear to be safer or more effective than the product actually is.
A recent study revealed that self-awareness might not be a cognitive function unique to primates and mammals with complex cognitive systems. This possibility was opened by the surprising performance of a species of fish commonly known as the cleaner wrasse when faced with the mirror test.
