By combining deep learning algorithms and statistical methods, investigators from the Institute of Evolutionary Biology (IBE), the Centro Nacional de Análisis Genómico (CNAG-CRG) of the Centre for Genomic Regulation (CRG) and the Institute of Genomics at the University of Tartu have identified, in the genome of Asiatic individuals, the footprint of a new hominid who cross bred with its ancestors tens of thousands of years ago.
SAN FRANCISCO, CA--January 16, 2019--You can think of DNA as a string of letters--As, Cs, Ts, and Gs--that together spell out the information needed for the construction and function of cells. Each cell in your body shares the same DNA. So, for cells to take on their differing roles, they must be able to turn on and off specific genes with precise control. The genes active in a brain cell, for instance, are different than those active in a skin cell.
A study published in the February 2019 "Pediatrics" journal suggests the majority of gay fathers and their children continue to experience stigma with potentially harmful physical and psychological effects, despite legal, media and social advances. Study participants specifically cited structural stigma, such as state laws and beliefs of religious communities, as affecting their experiences in multiple social contexts.
Cancer first develops as a single cell going rogue, with mutations that trigger aggressive growth at all costs to the health of the organism. But if cancer cells were accumulating harmful mutations faster than they could be purged, wouldn't the population eventually die out?
How do cancer cells avoid complete genetic meltdown?
To get at the heart of the matter, a team of scientists from Beijing and Taipei wanted to get a new hint at cancer vulnerability from a mutational perspective by probing the most famous cultured cancer cells, HeLa cells.
BINGHAMTON, N.Y. - What do songs by artists like Jay-Z and Public Enemy have in common? They feature representations of 'cop voice,' a racialized way of speaking that police use to weaponize their voices around people of color, according to faculty at Binghamton University, State University of New York.
Fluvial landscapes and the availability of water are of paramount importance for human safety and socioeconomic growth. Hydrologists know that identifying the boundaries of floodplains is often the first crucial step for any urban development or environmental protection plan.
Floodplain zoning is usually performed using complex hydrodynamic models, but modeling results can vary widely across methods and until now there has been no available unifying framework for global floodplain mapping.
New research, led by the University of Bristol, has shed new light on the eating habits of Neolithic people living in southeastern Europe using food residues from pottery extracts dating back more than 8,000 years.
With the dawn of the Neolithic age, farming became established across Europe and people turned their back on aquatic resources, a food source more typical of the earlier Mesolithic period, instead preferring to eat meat and dairy products from domesticated animals.
MADISON -- Hundreds of meters deep in the dark of the ocean, a shark glides toward what seems like a meal. It's kind of ugly, eel-like and not particularly meaty, but still probably food. So the shark strikes.
This is where the interaction of biology and physics gets mysterious -- just as the shark finds its dinner interrupted by a cloud of protective slime that appeared out of nowhere around an otherwise placid hagfish.
If you're angry about the political feud that drove the federal government to partially shut down, or about a golden parachute for a CEO who ran a business into the ground, you aren't alone -- but you probably won't do much about it, according to new research by Carnegie Mellon University's Tepper School of Business.
Hartford, Conn. - Restaurant, food, and beverage companies (food companies) target Hispanic and Black children and teens with ads almost exclusively for fast food, candy, sugary drinks, and unhealthy snacks, according to a new report from the Rudd Center for Food Policy & Obesity at the University of Connecticut, the Council on Black Health at Drexel University, and Salud America! at UT Health San Antonio.
Sophia Antipolis, 15 January 2019: Patients with type 2 diabetes should be prescribed physical activity to control blood sugar and improve heart health. That is one of the recommendations in a position paper(1) of the European Association of Preventive Cardiology (EAPC), a branch of the European Society of Cardiology (ESC). The paper is published today in the European Journal of Preventive Cardiology, a journal of the ESC.
Researchers from the University of Southern California have discovered that a drug currently being developed to treat stroke patients could also prevent Alzheimer’s disease. The study, which will be published January 15 in the Journal of Experimental Medicine, shows that the genetically engineered protein 3K3A-APC protects the brains of mice with Alzheimer’s-like symptoms, reducing the buildup of toxic peptides and preventing memory loss.
Scientists have made a step forward in understanding the evolution of human feet.
Unlike species such as chimpanzees, which have opposable digits on their feet, humans have evolved arched feet to enhance upright walking.
These arches were thought to be supported by plantar intrinsic muscles (PIMs) - but a study by the University of Queensland and the University of Exeter shows PIMs have a "minimal impact" on this.
Philadelphia, January 15, 2019 -- The American College of Physicians (ACP) today released the seventh edition of its Ethics Manual, published as a supplement to the current issue of Annals of Internal Medicine, ACP's flagship journal, and available online at http://www.annals.org.
NEW YORK, NY (January 14, 2019)--A new study of around 8,000 middle-aged and older adults found that swapping a half-hour of sitting around with physical activity of any intensity or duration cut the risk of early death by as much as 35 percent. The findings highlight the importance of movement -- regardless of its intensity or amount of time spent moving -- for better health.
The study was published online in the American Journal of Epidemiology.
