There are more than 400 known species of sharks inhabiting our planet’s marine ecosystems but detailed knowledge about most sharks is considerably lacking. Biologists often encounter barriers to studying sharks in captivity and in the wild due to factors such as their large size, relatively low demand in commercial markets, fast speeds, and wide habitat ranges.
The assessment of sperm morphology, determined by the cells’ shape and size, is an important part of male fertility testing. Previous research has suggested that only sperm with good sperm morphology are able to make their way to the egg in the woman’s body and fertilise it. Our knowledge of factors that influence sperm size and shape is very limited
Recent advances in technology have led to great developments in many fields – especially the field of medicine. In particular, better image detection has vastly improved electron microscopes, allowing for closer study of macromolecular complexes. The ability to visualize macromolecules in more detail, however, has raised even more questions to explore in the field of microscopy.
Reproductive medicine is a rapidly progressing field which generates a wealth of original and innovative research. As the European Society of Human Reproduction and Embryology (ESHRE) gets ready to welcome a new open access journal to its prestigious family, we meet the Editor-in-Chief, Professor Siladitya Bhattacharya, to find out how he sees the field developing in the future
Where will Uber stop? After the news that the Saudi’s have decided to invest $3.5bn in the company, came details of a further $2bn Uber wants to raise from financial markets using tecniques never deployed before by a start-up.
Recently, INTERPOL announced it had coordinated the shutdown of close to 5,000 websites illegally selling medicines online. Dubbed “Operation Pangea IX”, this ninth annual international week of action against illicit online pharmacies boasted the participation of over 103 countries from a multi-stakeholder coalition, led to 393 arrests, and resulted in the seizure of $53 million dollars worth of potentially dangerous medicines.
Rape threats against female bloggers. A major presidential candidate calling women “pigs” and even worse. Women being deprived of basic health care from Planned Parenthood because of anti-abortion politics.
The subject of combinatorial analysis or combinatorics (pronounced com-bin-a-TOR-ics) is concerned with such questions. We may loosely describe it as the branch of mathematics concerned with selecting, arranging, constructing, classifying, and counting or listing things.
How does a widow see her future? What can a widow see in the present? My late husband Gene D. Cohen is considered a founding father of Geriatric Psychiatry and the grandpappy of the field of Creativity and Aging. With his son and our daughter, I went to Chicago to receive his Hall of Fame Award, only four months after his passing.

Lesbian, Gay, Bisexual and Transgender (LGBT) Pride Month is celebrated annually in June to commemorate the 1969 Stonewall riots. The Stonewall Inn in New York City’s Greenwich Village was one of the city’s few gay bars or nightclubs at that time.
Over spring break, I spent a day in Tombstone, Arizona. This is the town where, if you don’t know the story, Wyatt Earp and his brothers, accompanied by their friend Doc Holliday, had a shootout with a group of cattle rustlers at the OK Corral. Though the Earp brothers wore the badges, when the tale is told the hero is usually Doc Holliday—noted gambler, crack shot, prodigious drinker
US government’s premiere test program finds cancer risk from cell phone radiation: a game-changing global wake-up call
Have you heard that cell phones cause cancer, then they don’t, then they do? Confused enough yet? Let me break it down for you. Contrary to some claims, the new US government study by the National Toxicology Program (NTP) is hardly a shot in the dark or a one-off event. With this largest best-conducted animal study, we now have three different studies within the past six years
Preimplantation genetic screening: after 25 years and a complete make-over, the truth is still out there
More than 25 years ago, it was found that human embryos of about three days old cultured in the lab, showed chromosomal abnormalities in more than half of them. Many of these abnormalities were not coming from the sperm or the egg, but occurred after the embryo has cleaved two times, obtaining four cells, or three times, reaching the eight-cell stage.
When looking at the use of drugs in modern medicine, specifically anaesthesia and intensive care – it is important to realise that this is nothing new at all. The first attempts at general anaesthesia were most likely herbal remedies and opiates, evidence of which has been found as early as the third millennium BCE. Antiseptics, from the Greek words anti (against) and sepsis (decay) were also used in ancient times
Two hundred years ago this month, Mary Shelley had the terrifying ‘waking dream’ that she subsequently molded into the greatest Gothic novel of all time; Frankenstein. As all who have read the book or seen one of the many film adaptations will know, the ‘monster’ cobbled together out of human odds and ends by rogue scientist, Victor Frankenstein, is galvanised into existence by the power of electricity.
At a theoretical level, the concept of artificial intelligence has fueled and sharpened the philosophical debates on the nature of the mind, intelligence, and the uniqueness of human beings. Insights from the field have proved invaluable to biologists, psychologists, and linguists in helping to understand the processes of memory, learning, and language.
