Report Claims 100 Million Will Die from Climate Change by 2030

storm-gathering

A new report commissioned by 20 different governments states that more than 100 million people will die by 2030 if nothing is done to tackle climate change. Global economic growth will also be cut by 3.2% of gross domestic product (GDP).

Vampyroteuthis infernalis, the vampire squid, which technically isn’t a squid at all, is a cephalopod that lives 3,000 feet deep in warm waters. In the deep pelagic zone, there is little oxygen and V. infernalis reaches a size of just 30 cm in adulthood.

Freelancers Workers Are Generally Happier Than Permanent Employees

People usually cite the lack of job security and benefits as the main reasons why they wouldn’t want to be self-employed. However, a new study indicates that many people are becoming contractual workers and these independent workers are finding a happier job satisfaction than their permanently-employed colleagues.

A new study indicates that male DNA, left over from pregnancy with a male fetus, can persist in a woman’s brain throughout the rest of her life. Although the exact biological impact of the DNA is yet unclear, the study found that women with more male DNA in their brains were less likely to suffer from Alzheimer’s disease, suggesting that male DNA could help protect mothers from this disease.

African Spiny Mice Regenerate Lost Tissue

acomys-kempi

African spiny mice, specifically the species Acomys kempi and Acomys percivali, have skin that is brittle and can be easily torn. This evolutionary adaptation allows them to escape predators by jettisoning whole patches of skin when caught or bitten.

LaCie Portable Thunderbolt SSD: Fasted Rugged HD Available?

Sure, Thunderbolt is fast, but there aren’t many devices that you can buy that work with it, leaving Apple fanboys crying in their closets. LaCie has released a new Thunderbolt-compatible portable drive, that uses a speedy solid-state drive for that extra special cherry on top. It also supports USB 3.0 for PC users.

Two 305-million-year-old insect nymphs were scanned in high resolution in order to construct three-dimensional portraits. The two insects were scanned using fossils from the Carboniferous Period, which lasted from 359.2 Ma (million years ago) to the beginning of the Permian Period, at 299 Ma

Inhibition of MicroRNAs in Mice Can Attenuate Cardiovascular Stress

Cardiac stress that’s caused by a heart attack or high blood pressure will frequently lead to pathological heart growth and eventually lead to heart failure. Researchers have discovered that two micro-scale RNA molecules, microRNA miR-212 and miR-132 play a role in this detrimental development in mice. When these molecules were inhibited, the mice were protected against pathological heart growth and failure. Researchers hope to adapt these findings and develop therapeutic approaches that would work in humans.
