Squids' birthday influences mating

The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become 'consorts' which fight for mating opportunities. Those which hatch later become 'sneakers,' which use more clandestine mating tactics. Researchers found that the mating tactic determined by the birth date was fixed for the squid's whole life. Understanding how mating tactics are influenced by birth date, and the environmental conditions at that time, can help researchers consider how squid might be affected by climate change and the implications for marine resource management.

A decade of aphantasia research: what we've learned about people who can't visualize

People who can't visualize an image in their mind's eye are less likely to remember the details of important past personal events or to recognize faces, according to a review of nearly ten years of research. People who cannot bring to mind visual imagery are also less likely to experience imagery of other kinds, like imagining music, according to new research by the academic who first discovered the phenomenon.

New imaging method illuminates oxygen's journey in the brain

A new bioluminescence imaging technique has created highly detailed, and visually striking, images of the movement of oxygen in the brains of mice. The method, which can be easily replicated by other labs, will enable researchers to more precisely study forms of hypoxia in the brain, such as the denial of oxygen to the brain that occurs during a stroke or heart attack. The new research tool is already providing insight into why a sedentary lifestyle may increase risk for diseases like Alzheimer's.

Alcohol raises heart disease risk, particularly among women

Young to middle-aged women who reported drinking eight or more alcoholic beverages per week--more than one per day, on average--were significantly more likely to develop coronary heart disease compared with those who drank less, finds a study presented at the American College of Cardiology's Annual Scientific Session. The risk was highest among both men and women who reported heavy episodic drinking, or 'binge' drinking, and the link between alcohol and heart disease appears to be especially strong among women, according to the findings.

Evolution of the most powerful ocean current on Earth

The Antarctic Circumpolar Current plays an important part in global overturning circulation, the exchange of heat and CO2 between the ocean and atmosphere, and the stability of Antarctica's ice sheets. An international research team has now used sediments taken from the South Pacific to reconstruct the flow speed in the last 5.3 million years. Their data show that during glacial periods, the current slowed; during interglacials, it accelerated. Consequently, if the current global warming intensifies in the future, it could mean that the Southern Ocean stores less CO2 and that more heat reaches Antarctica.

A new excavation at one site in Germany turned up 45,000-year-old bone fragments that, when analyzed for mitochondrial DNA, proved to be from Homo sapiens. This is the earliest evidence that modern humans overlapped with Neanderthals in northwest Europe, thousands of years before Neanderthals went extinct.

Gravity helps show strong force strength in the proton

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force, a powerful mediator of particle interactions in the subatomic realm. The research has revealed, for the first time, a snapshot of the distribution of the shear strength of the strong force inside the proton -- or how strong an effort must be to overcome the strong force to move an object it holds in its grasp. At its peak, the nuclear physicists found that a force of over four metric tons would be required to overcome the binding power of the strong force.

New pieces in the puzzle of first life on Earth

Microorganisms were the first forms of life on our planet. The clues are written in 3.5 billion-year-old rocks by geochemical and morphological traces, such as chemical compounds or structures that these organisms left behind. However, it is still not clear when and where life originated on Earth and when a diversity of species developed in these early microbial communities. Evidence is scarce and often disputed. Now, researchers have uncovered key findings about the earliest forms of life. In rock samples from South Africa, they found evidence dating to around 3.42 billion years ago of an unprecedentedly diverse carbon cycle involving various microorganisms. This research shows that complex microbial communities already existed in the ecosystems during the Palaeoarchaean period.

Planetary Commons: Fostering global cooperation to safeguard critical Earth system functions

Tipping elements of the Earth system should be considered global commons, researchers argue. Global commons cannot -- as they currently do -- only include the parts of the planet outside of national borders, like the high seas or Antarctica. They must also include all the environmental systems that regulate the functioning and state of the planet, namely all systems on Earth we all depend on, irrespective on where in the world we live. This calls for a new level of transnational cooperation, leading experts in legal, social and Earth system sciences say. To limit risks for human societies and secure critical Earth system functions they propose a new framework of planetary commons to guide governance of the planet.

A recent amateur discovery pushes back the origin of kelp to 32 million years ago, long before these creatures appeared. A new analysis suggests the first kelp grazers were extinct, hippo-like animals called desmostylians.
