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.

A substantial proportion of young Britons are not ready for their first sexual activity- whatever their age-and lose their virginity "under circumstances that are incompatible with positive sexual health," reveals research published online in BMJ Sexual & Reproductive Health.

Rather than focusing on the age at which a young person starts having sex, a much more nuanced approach is needed to this key milestone, say the researchers, in recognition of the fact that "young age alone doesn't threaten sexual health any more than older age safeguards it."

Back pain is among the most frequently reported health problems in the world. New research published in Arthritis Care & Research, an official journal of the American College of Rheumatology and the Association of Rheumatology Health Professionals, examines patterns in back pain over time and identifies the patient characteristics and the extent of healthcare and medication use (including opioids) associated with different patterns.

Scientists have created a tool which can more accurately identify ancient Eurasian populations

The tool allows people to discover how similar they are to the Roman Britons, Vikings or ancient Israelites

Scientists at the University of Sheffield studying ancient DNA have created a tool allowing them to more accurately identify ancient Eurasian populations, which can be used to test an individual's similarity to ancient people who once roamed the earth.

REDWOOD CITY, CA -January 14, 2019 - Scientists at Numenta propose a major new theory about how the human brain works. While neuroscientists have amassed an enormous amount of detailed factual knowledge about the brain, there remains no unifying theory as to what intelligence is and how the brain produces it. In their paper, "A Framework for Intelligence and Cortical Function Based on Grid Cells in the Neocortex," Numenta researchers describe a broad framework for understanding what the neocortex does and how it works.

Hershey, Pa -- People with cancer are more than four times more likely to commit suicide than people without cancer, according to Penn State College of Medicine researchers.

In a study using data on more than eight million cancer patients in the United States, the researchers also found that among people with cancer, white males; patients who were diagnosed at a younger age; and patients with lung, head and neck, testicular cancer, and lymphomas were more likely to commit suicide.

In a four-year study, a group of science faculty finds that student buy-in to a new curriculum, and therefore satisfaction, increases with each successive undergraduate cohort -- and learning gains did not suffer. The researchers say the results of their longitudinal study should help encourage college faculty and administration to create, adapt, and support innovative courses for their students.
