Huge ancient ice wall across the Bering Strait may have triggered Ice Age

Michael Irving December 20, 2018

Most climate change events can be linked to specific causes, but the cause of the last major shift, which occurred about a million years ago, has remained a mystery. By taking samples from the ocean floor of the Bering Sea, a new study may have uncovered the mechanism behind this outlier event.

A new study suggests the last ice age was caused by an ice wall across the ...

Microplastics discovered in the guts of sea turtles all over the world

Nick Lavars December 12, 2018

There remains a lot we don't know about the whereabouts of the all the plastic waste that washes into the ocean each year, but scientists are continuing to discover bits and pieces in increasingly concerning places, a list that now includes turtles.

Warm Neptune exoplanet atmosphere inflates to resemble a balloon

Anthony Wood December 7, 2018

An international team of astronomers has discovered that helium atoms are causing the atmosphere of a "warm-Neptune" exoplanet to expand like a party balloon before escaping into the cold expanse of space.

Novel compounds turn old cells young again in promising new anti-aging research

Rich Haridy August 7, 2018

A new study from researchers at the University of Exeter has shown how three specifically designed compounds can target the mitochondria in older human cells, effectively rejuvenating those cells and making them act young again to reverse key signs of aging.

Are fish losing their sense of smell due to more-acidic oceans?

Ben Coxworth July 24, 2018

A couple of years ago we heard about a study conducted at Britain's University of Exeter, which indicated that increasingly acidic oceans were harming fishes' sense of smell. New research now reinforces that finding, and it could mean that trouble is in store for the marine ecosystem.

Although European sea bass were used in the study, the scientists state that the findings are ...

LEDs cut seabird death toll from fishing by 85 percent

Ben Coxworth July 11, 2018

According to the University of Exeter, an estimated 400,000 diving seabirds die annually by getting caught in gill nets intended to catch fish. A new study indicates that the majority of those deaths could be avoided, however, if the nets were to be equipped with inexpensive green LEDs.

Needle-free: 10-year study confirms rare diabetes can be treated with tablets

Nick Lavars June 5, 2018

For a long time, insulin injections have simply been a fact of life for people – including babies – suffering from neonatal diabetes. But a new 10-year study has now shown tablets to be just as effective, with recipients hailing the new approach as a "miracle treatment."

Needles could now be a thing of the past for sufferers of neonatal diabetes

Astronomers spot the first cloud-free exoplanet

Nick Lavars May 8, 2018

An important arm of exoplanet research involves the study of the atmospheres that surround these distant worlds. The molecules they hold can reveal valuable insights into what kind conditions can be found there – along with ones that cannot.

Helium discovered in exoplanet atmosphere for the first time

Anthony Wood May 2, 2018

An international team of astronomers has made the first-ever detection of helium in the atmosphere of an extrasolar world. The new technique used to make the discovery could pave the way for scientists hoping to reveal the atmospheres of distant Earth-sized exoplanets.

Stable and scalable photo-electrode “strongest candidate yet” for renewable hydrogen generation

Darren Quick April 29, 2018

Using the power of the sun to split water and produce hydrogen fuel is one of the most promising clean energy technologies being pursued. Now researchers at the University of Exeter have created a semiconductor material that should help make it viable.
