Chemicals found in vegetables prevent colon cancer in mice

Chemicals produced by vegetables such as kale, cabbage and broccoli could help to maintain a healthy gut and prevent colon cancer, a new study shows.

Zombie gene protects against cancer -- in elephants

LIF6, a dead gene that came back to life, prevents cancer by killing cells with DNA damage.

Snake fungal disease alters skin microbiome in eastern Massasaugas

In the first study of its kind, researchers characterized the skin microbiome of a population of free-ranging snakes to begin to understand how the animals' environmental microbial community may

Early opaque universe linked to galaxy scarcity

A team of astronomers has made a surprising discovery: 12.5 billion years ago, the most opaque place in the universe contained relatively little matter.

Origins and spread of Eurasian fruits traced to the ancient Silk Road

Studies of ancient plant remains from a medieval archaeological site in the Pamir Mountains of Uzbekistan have shown that fruits, such as apples, peaches, apricots, and melons, were cultivated in the

Magnetic gene in fish may someday help those with epilepsy, Parkinson's

An aquarium fish that senses the Earth's magnetic field as it swims could help unlock how the human brain works and how diseases such as Parkinson's and other neurological disorders function.

Unraveling the nature of 'whistlers' from space in the lab

Scientists have presented research on a curious cosmic phenomenon known as 'whistlers' -- very low frequency packets of radio waves that race along magnetic field lines. The study provides new

Medicaid expansion states see rise in coverage for low income adults with substance use disorders

The percentage of low-income Americans with substance use disorders who were uninsured declined more sharply in states that chose to expand Medicaid under the Affordable Care Act versus states that

New approach to treating chronic itch

Two receptors in the spinal cord and the right experimental drug: Researchers have discovered a new approach that suppresses itch. In a series of experiments in mice and dogs they successfully

How MERS Coronavirus evolves to infect different species

New research shows how MERS-CoV can adapt to infect cells of a new species, which suggests that other coronaviruses might be able to do the same.

Effects of climate warming seen in tallgrass prairie ecosystem

Ecologists have completed a new study on the effects of climate warming on soil microbes in a long-term climate change experiment at a tallgrass prairie ecosystem. The new study shows that climate

Models give synthetic biologists a head start

Researchers have developed mathematical models to predict the performance of multi-input synthetic biological circuits that can be used to engineer bacteria and other organisms to regulate cellular

Potential guidance for gastric cancer treatment

Researchers have discovered that gastric cancer tissue samples bearing mutation of a specific gene, MUC16, too are associated with higher tumor mutation loads. Also known as tumor mutation burdens,

Security gaps identified in Internet protocol 'IPsec'

Researchers have demonstrated that the Internet protocol 'IPsec' is vulnerable to attacks. The Internet Key Exchange protocol 'IKEv1', which is part of the protocol family, has vulnerabilities that

Natural refrigerant replacements could reduce energy costs and conserve the environment

The 1987 Montreal Protocol and the 1997 Kyoto Protocol called for countries around the world to phase out substances that deplete the ozone layer, but many HVAC systems still use synthetic

Inching closer to a soft spot in isoniazid-resistant tuberculosis

Researchers comparing clonal strains of the mycobacteria that cause TB, before and after they developed resistance to a first-line drug, found that a single genetic change may not always have

Light-engineered bacterial shapes could hold key to future labs-on-a-chip

Scientists have used light patterns to control the swimming speed of bacteria and direct them to form different shapes.

Cancer-fighting drugs also help plants fight disease

Cancer-fighting drugs used on humans can help plants fight disease as well. That discovery, by plant pathologists, could help scientists develop new pathways for plants to battle infection.

Diving robots find Antarctic winter seas exhale surprising amounts of carbon dioxide

A new study uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open

Deaths from resident-to-resident incidents in dementia offers insights to inform policy

Analyzing the incidents between residents in dementia in long-term care homes may hold the key to reducing future fatalities among this vulnerable population, according to a new research.
