(Credit: Dennis Jarvis/Flickr) (Inside Science) — In the 6th century B.C., the Babylonian king Nebuchadnezzar II, fearful that the Egyptians would cut off the Babylonian trade routes to the eastern Mediterranean region known as the Levant, invaded and laid siege to Jerusalem to block them. His army destroyed the temple the Hebrew king Solomon built there, and forced
Participants in a recent trial experienced old memories, vividly. Halfpoint/Shutterstock.com Alzheimer’s disease is one of the most dreaded diagnoses, and the fear is particularly acute among older people. This complex brain disorder, which usually affects older individuals, can cause many cognitive disabilities, most notably memory impairment. About 5.7 million Americans are living with Alzheimer
MRI scans of patients show patients with Alzheimer’s disease. (Credit: Atthapon Raksthaput/Shutterstock) Scientists are still unraveling why Alzheimer’s disease affects men and women disproportionately. Out of the five million Americans who have it, about 64 percent are women. Once in their 60s, women are twice as likely to develop Alzheimer’s than breast cancer, and more than twice as likely to d
Biomedical engineers at Duke University have used a previously unexplored CRISPR technology to accurately regulate and edit target genes in human cells. With this new approach, the researchers hope to dramatically expand the CRISPR-based tools available to biomedical engineers, opening up a new and diverse frontier of genome engineering technologies.
Cats have a reputation for being aloof and independent. But a study of the way domestic cats respond to their caregivers suggests that their socio-cognitive abilities and the depth of their human attachments have been underestimated. The findings reported in the journal Current Biology on Sept. 23 show that, much like children and dogs, pet cats form secure and insecure bonds with their human care
In a paper published in Nature Ecology and Evolution, a group of researchers argue that our evolutionary past must be understood as the outcome of dynamic changes in connectivity, or gene flow, between early humans scattered across Africa. Viewing past human populations as a succession of discrete branches on an evolutionary tree may be misleading, they said, because it reduces the human story to
In the first population-based study to examine the association between onion and garlic consumption and breast cancer in Puerto Rico, UB and University of Puerto Rico researchers found that women who ate sofrito more than once per day had a 67% decreased breast cancer risk.
Children of parents who smoke had a significantly increased chance of developing atrial fibrillation later in life, according to a study published today in the Journal of the American College of Cardiology. The findings highlight a new association between secondhand smoke exposure and heart rhythm disorder risk.
Researchers at Chalmers University of Technology, Sweden, have disproved the prevailing theory of how DNA binds itself. It is not, as is generally believed, hydrogen bonds which bind together the two sides of the DNA structure. Instead, water is the key. The discovery opens doors for new understanding in research in medicine and life sciences. The findings are published in PNAS.
A few years ago, the LIGO/Virgo collaboration detected gravitational waves arising from a binary black hole merger using the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO). This eventually led to the observation of black holes with masses that are roughly 30 times the mass of the sun. Since then, researchers worldwide have been investigating these black holes, spec
Leader after leader told the United Nations on Monday that they will do more to prevent a warming world from reaching even more dangerous levels. But as they made their pledges at the Climate Action Summit, they and others conceded it was not enough.
Giant, predatory croc-like animals that lived during the Triassic period in southern Africa preyed on early dinosaurs and mammal relatives 210 million years ago. These predators, known as “rauisuchians” preyed on early herbivore dinosaurs and their mammal relatives living at the time, according to Wits Masters student Rick Tolchard.
Feeling ashamed of your weight doesn’t make you healthier. (Unsplash/) Roughly 70 percent of American adults are considered overweight or obese by BMI standards , yet a 2016 Gallup poll found only 37 percent actually realize it. Stats like these have inspired many pundits and armchair physicians (and more than a few actual physicians) to suggest we should, as a society, make fat people more aware
In India, discrimination among social classes, or castes, forces those with lesser means to take dangerous, reviled jobs such as sewer cleaning. (Chandan Khanna/AFP/Getty Images/) The Indian government defines a “manual scavenger” as a person who physically carries human excreta. Often without safety gear—no helmets, masks, or gloves—these workers plumb the manholes of Mumbai, waist-deep in grey
This is the first study to look at cat attachment by looking at bonding styles, the same way researchers study dogs and human babies. (Pixabay/) Cats can seem mysterious and aloof. They stare at nothing for hours on end and have very specific petting requirements . These and similarly strange behaviors have baffled and amused long-suffering human companions since they sailed with the Vikings (and
Once you know how to pose, you won’t even need colors. (Harry Guinness/) In an era when most people carry a camera in their pockets, and a large amount of the pictures taken of us will eventually be posted on the internet forever, posing properly for a photo is an important skill everyone should have. You don’t have to look like a runway model, you just have to make sure you portray yourself in a
There’s currently no peer-reviewed research published in any major scientific journals backing up the hormone diet’s claims. (Shutterstock/Gts/) When it comes to losing weight and getting healthy, there never seems to be a shortage of diet and fitness crazes claiming to hold the secret to easy, sustainable weight loss. Some of the most recent popular diet crazes include the ketogenic diet (low ca
Maybe don’t hire this person, though—that planner shows they’re still working on stuff from four years ago. (Avel Chuklanov via Unsplash/) There never seems to be enough hours in the day, and if that’s a feeling you experience often, you’ve got two options: Somehow warp space and time to extend each day beyond 24 hours, or delegate out some of your most time-consuming and energy-draining tasks. W
The ancient Incan sanctuary of Machu Picchu is considered one of humanity’s greatest architectural achievements. Built in a remote Andean setting atop a narrow ridge high above a precipitous river canyon, the site is renowned for its perfect integration with the spectacular landscape. But the sanctuary’s location has long puzzled scientists: Why did the Incas build their masterpiece in such an ina
Cats have a reputation for being aloof and independent. But a study of the way domestic cats respond to their caregivers suggests that their socio-cognitive abilities and the depth of their human attachments have been underestimated. The findings show that, much like children and dogs, pet cats form secure and insecure bonds with their human caretakers.
Scientists have figured out how to capture heat and turn it into electricity. The discovery could create more efficient energy generation from heat in things like car exhaust, interplanetary space probes and industrial processes.
Mosasaurs were true sea monsters of late Cretaceous seas. These marine lizards — related to modern snakes and monitor lizards — grew as long as fifty feet, flashed two rows of sharp teeth, and shredded their victims with enormous, powerful jaws.
What does it take for a human to trust a robot? That is what researchers are uncovering in a new study into how humans and robots work together. Research into human-agent teaming, or HAT, has examined how the
