Catching a new (sea) star
Researchers have discovered a new species of sea star (also known as starfish). The discovery came about thanks to collaborative work among researchers, fishers, and aquarium and museum staff. The starfish, which has been named Paragonaster hoeimaruae, belongs to the family Pseudarchasteridae. It is a distinctive red and beige color, with five arms and spans just over 10 centimeters.

Nature's design marvel: How shark skin's denticles adapt to wide speed
New findings on how sharks achieve drag reduction could inspire the design of riblets for more efficient aircraft and boats. In their investigation of great white shark denticles, researchers found that ridge height and spacing play crucial roles in drag reduction at different swimming speeds. Higher middle ridges aid sharks in efficient cruising at slower speeds, while the lower side ridges become more critical for drag reduction during high-speed hunting bursts. The analysis also suggests that the speeds of an extinct giant shark, megalodon, may not much differ from those of the white shark.

Scientists and climate change: Extreme concern and high level of engagement
Scientists from across academic disciplines are extremely concerned about climate change. Many of them have already changed their own lifestyles or engaged in advocacy and protest, with even more being willing to do so in future. This is evident from a large-scale survey of scientists from all over the world.

New study highlights scale and impact of long COVID
Researchers analyzed dozens of previous studies into long COVID to examine the number and range of people affected, the underlying mechanisms of disease, the many symptoms that patients develop, and current and future treatments.

Link between global warming and rising sea levels
A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.

Allergy cells' hidden secret
Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation. Now, researchers have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils. This surprising discovery sheds new light on how our immune system works, particularly during allergic reactions.

Trying to limit calories? Skip the dip, researchers advise
Snacks provide, on average, about one-fourth of most people's daily calories. With nearly one in three adults in the United States overweight and more than two in five with obesity, researchers are investigating how Americans can snack smarter.

Retreat of tropical glaciers foreshadows changing climate's effect on the global ice
As they are in many places around the globe, glaciers perched high in the Andes Mountains are shrinking. Now, researchers have uncovered evidence that the high-altitude tropical ice fields are likely smaller than they've been at any time since the last ice age ended 11,700 years ago.

Climate anomalies may play a major role in driving cholera pandemics
New research suggests that an El Nino event may have aided the establishment and spread of a novel cholera strain during an early 20th-century pandemic, supporting the idea that climate anomalies could create opportunities for the emergence of new cholera strains.

Easy tool helps estimate fall risks
Researchers have developed a formula and easy-to-use assessment tool for estimating fall risks using a database of older adults. Preventing falls among older adults is expected to extend life expectancy and reduce medical and nursing care costs.
