Wyoming research shows early North Americans made needles from fur-bearers

A Wyoming archaeological site where people killed or scavenged a Columbian mammoth nearly 13,000 years ago has produced yet another discovery that sheds light on the life of these early inhabitants of North America. Wyoming State Archaeologist Spencer Pelton and colleagues at the University of Wyoming and other institutions have found that these Paleolithic humans made needles from the bones of fur-bearers -- including foxes; hares or rabbits; and cats such as bobcats, mountain lions, lynx and possibly even the now-extinct ...

Ultraprocessed food intake and psoriasis

About The Study: The results of this study showed an association between high ultraprocessed food intake and active psoriasis status. After adjustments for age, body mass index (BMI), alcohol intake, and comorbidities, the results remained significant, suggesting that ultraprocessed food intake has a proinflammatory action separate from high BMI.

A matter of life and death
Science

A matter of life and death

Cellular death is a fundamental concept in the biological sciences. Given its significance though, its definition depends on the context in which it takes place, and lacks a general mathematical definition. Researchers from the University of Tokyo propose a new mathematical definition of death based on whether a potentially dead cell can return to a predefined “representative state of living,” which are the states of being that we can confidently call “alive.” The researchers’ work could be useful for biological researchers and future medical research. While it’s ...

What a gut fungus reveals about symbiosis and allergy

A fungus discovered in the mouse stomach may hold a key to fungal evolution within the gastrointestinal tract, according to new research led by Weill Cornell Medicine investigators. The finding suggests that preclinical studies until now have overlooked a major influencer of mouse physiology. Scientists recently have come to appreciate the importance, for human health and disease, of microbes—often called “commensals”—that naturally dwell in the gut. Bacterial commensals, for example, are known to have ...

Autism and neural dynamic range: insights into slower, more detailed processing

A new study has linked distinct neural and behavioral characteristics in autism spectrum disorder to a simple computational principle. Centered on the “dynamic range” of neurons, which reflects how gradually or sharply they respond to input, the study suggests that individuals with autism spectrum disorder have an increased dynamic range in their neuronal response, resulting in a more detailed but slower response to changes. This research defies previous descriptions of ASD as a “broken cog in the machine” and provides a deeper, richer account of the computational basis of ASD. [Hebrew University of Jerusalem]– Researchers Dr. Yuval Hart and Oded ...

Simple secret to living a longer life

If everyone in the United States population was as active as the top 25 per cent, individuals over the age of 40 could add five years to their life, according to a new study led by Griffith University researchers. Physical activity has long been known to be good for health, however estimates have varied regarding how much benefit could be gained from a defined amount of activity, both for individuals and for populations. This latest study used accelerometry to gain an accurate view of the population’s physical activity levels instead of relying on survey responses as per other studies, and found the benefits were around twice as strong ...

Drinking plenty of water may actually be good for you

Public health recommendations generally suggest drinking eight cups of water a day. And many people just assume it’s healthy to drink plenty of water. Now researchers at UC San Francisco have taken a systematic look at the available evidence. They concluded that drinking enough water can help with weight loss and prevent kidney stones, as well as migraines, urinary tract infections and low blood pressure. “For such a ubiquitous and simple intervention, the evidence hasn’t been clear and the benefits were not well-established, so we wanted to take a closer look,” said senior and corresponding author Benjamin Breyer, MD, MAS, the Taube ...

Depression can cause period pain, new study suggests

Women are twice as likely as men to suffer from depression and often experience more severe physical symptoms. This gender difference is particularly evident during reproductive years and dramatically impacts the lives of hundreds of millions of people worldwide. However, although links between mental health and reproductive health have been found, the associations have remained underexplored. In a new study published in Briefings in Bioinformatics, researchers from China and the UK have found that depression can increase the chances of a person experiencing menstrual pain (dysmenorrhea).

To catch financial rats, a better mousetrap

Enron. Lehman Brothers. More recently, General Electric and Supermicro. During the past quarter century, a variety of high-profile companies have been caught cooking their books. But they’re often not caught before they’ve cost investors billions of dollars. That’s why analysts have long tried to sniff out businesses that may be using questionable or flat-out illegal accounting tricks to hide poor performance. New research from Urooj Khan, accounting professor and the Deloitte & Touche Centennial Faculty Fellow at Texas McCombs, proposes a new and more effective way to gauge companies’ “earnings quality.” In analyses of corporate ...

Great apes visually track subject-object relationships like humans do

Great apes track events with their eyes in the same way that humans do, according to a study published November 26th in the open-access journal PLOS Biology by Vanessa Wilson from the University of Neuchatel, Switzerland, and colleagues. When watching a cat chase a mouse, humans will alternate looking at cat and mouse, using the information to connect the two into what’s called an agent-patient relationship—with the cat as the agent and the mouse as the patient. This cognitive mechanism is thought to be ...

New era in amphibian biology

Amphibians hold a significant place in evolution, representing the transition from aquatic to terrestrial lifestyles. They are crucial for understanding the brain and spinal cord of tetrapods—animals with four limbs, including humans. A group of scientists led by a team at the Institute of Science and Technology Austria (ISTA) now shows how harmless viruses can be used to illuminate the development of the frog nervous system. The results have now been published in Developmental Cell. Virus. When you hear the word, you probably shudder. But not all viruses are bad or cause disease. Some are even used for therapeutic ...

Sports betting and financial market data show how people misinterpret new information in predictable ways

Let’s say it’s a home game for the Golden State Warriors and Steph Curry shows he’s still got it, sinking back-to-back three-pointers minutes into the first quarter. The fans at Chase Center take notice, and so do the betting markets, where the odds move in the Warriors’ favor. Yet it’s a long game. The away team comes back, and with just 10 seconds to go, the Warriors are down by two and have just missed a shot. A victory is unlikely, and the betting odds should have shifted to reflect that near-certainty. ...

Delay and pay: Tipping point costs quadruple after waiting

RICHLAND, Wash. —Tip the first tile in a line of dominoes and you’ll set off a chain reaction, one tile falling after another. Cross a tipping point in the climate system and, similarly, you might spark a cascading set of consequences like hastened warming, rising sea levels and increasingly extreme weather. It turns out there’s more to weigh than catastrophic environmental change as tipping points draw near, though. Another point to consider, a new study reveals, is the cost of undoing the damage. The cost of reversing the effects of climate change—restoring melted polar sea ice, for ...

A clue to what lies beneath the bland surfaces of Uranus and Neptune

Diamond rain? Super-ionic water? These are just two proposals that planetary scientists have come up with for what lies beneath the thick, bluish, hydrogen-and-helium atmospheres of Uranus and Neptune, our solar system's unique, but superficially bland, ice giants. A planetary scientist at the University of California, Berkeley, now proposes an alternative theory — that the interiors of both these planets are layered, and that the two layers, like oil and water, don't mix. That configuration neatly explains the planets' unusual magnetic fields and implies ...
