Arctic wild goose chase threatens chicks as temperatures rise

Rising temperatures in the Arctic are encouraging Barnacle geese to speed up their migration journeys north every spring, says a new study.

But their efforts to go faster are leaving them too drained to lay their eggs early when they arrive, according to BBC.

This is bad news for the species as their chicks are hatched too late to take advantage of the best food, so fewer are surviving.

The scientists involved say the birds will have to adapt and migrate earlier.

We may have less control over our thoughts than previously assumed

Think you're totally in control of your thoughts? Maybe not as much as you think, according to a new San Francisco State University study that examines how thoughts that lead to actions enter our consciousness.

While we can "decide" to think about certain things, other information -- including activities we have learned like counting -- can enter our subconscious and cause us to think about something else, whether we want to or not. Psychologists call these dispositions "sets," explains Professor of Psychology Ezequiel Morsella, one of four authors on a new study that examines how sets influence what we end up thinking about, according to Science Daily.

Newborn planet pictured for first time

Astronomers have captured this image of a planet that's still forming in the disk of gas and dust around its star.

Researchers have long been on the hunt for a baby planet, and this is the first confirmed discovery of its kind, according to BBC.

Young dwarf star PDS 70 is less than 10 million years old, and its planetary companion is thought to be between five and six million years old.

Why scientists are counting seal pups in the Thames Estuary

Sixty years ago the Thames Estuary was regarded as "biologically dead" and largely devoid of wildlife.

But, in recent years seals have returned to the Thames as well as to the coastal and low-lying lands bordering the estuary, according to BBC.

Last year, scientists recorded more than 3,500 harbour and grey seals.

Now, they are starting the first count of seal pups to see how important the area is a breeding ground.

Pulse wave analysis provides reliable information on heart health in young people

Arterial stiffness is one of the early signs of cardiovascular disease, and arterial stiffening has been observed in children. A recent study suggests that an easy-to-use, non-invasive method can produce reproducible estimates of arterial stiffness in adolescents aged 16-19 years, according to Science Daily.

The study investigated the short-term reproducibility of aortic pulse wave velocity as a measure of arterial stiffness and of augmentation index as a measure of peripheral arterial tone among 55 adolescents aged 16-19. The study also investigated the effects of cardiorespiratory fitness and body fat percentage on the reproducibility. Arterial stiffness and peripheral arterial tone were measured with a non-invasive, oscillometric pulse wave analyzer, cardiorespiratory fitness using a maximal cardiopulmonary exercise test on a cycle ergometer, and body fat percentage through bioelectrical impedance analysis.
